MS Product Features and BenefitsMS Product Features and Benefits

Fast, Convenient Filter ReplacementEach unit includes a 1-inch throw-away filter in a factory-mounted filter bracket designed to accommo-date a return air duct connection. Filters are removed horizontally. Four-sided filter racks are available as an option for both vertical and horizontal units. See Four-Sided Filter Rack on page 11.

Units are designed to accommodate high- efficiency filters like 2 Merv 8 and Merv 13.

Easy Filter Replacement

Quiet, Efficient Refrigeration SystemAll units feature a sealed refrigerant circuit including a hermetic compressor with overload protection, balance-port expansion valve, finned tube air-to-refrigerant heat exchanger, tube-in-tube water-to-refrigerant heat exchanger, refrigerant reversing valve and service ports.

Floating Base Plate

Compressors

Compressors are high efficiency and designed for heat pump duty. They are internally spring isolated (if reciprocating type) for maximum sound attenuation. A 10 gauge steel mass plate under the compressor minimizes vibration transmission to the cabinet for quiet operation. High-density rubber isolators between the base plate and the unit base pan isolate both noise and vibration.

The water-to-refrigerant heat exchanger is a coaxial coil with a convoluted copper inner tube and a steel outer tube. The convoluted tube has increased heat transfer surface area per unit length for greater performance. 90-10 cupro-nickel inner tubes are an option. It is rated for 600 psig on the refrigerant side and 400 psig on the water side. Optimum heat transfer is achieved with a counter-flow arrangement of water and refrigerant during condensing.

Coaxial Water-To-Refrigerant Heat Exchanger

The airside coil is a copper tube, aluminum finned type selected for high efficiency and is rated for 650 psig working pressure.

Air Coil

The reversing valve is pilot-operated, of the sliding piston type, with replaceable, encapsulated magnetic coils, ener-gized only during the cooling cycle.

Reversing Valve

Safety controls include high- and low-refrigerant pressure switches (loss of charge protection). A lockout relay built into the standard microprocessor board prevents the com-pressor from operating if any safety switch trips.


MS Product Features and BenefitsQuiet, Easy-Access Air Handling SectionThe air handling section includes the blower wheel and housing, motor, discharge outlet and drain pan that is located under the air coil. Components are separated from the compressor section to limit noise transmission. The forward-curve, centrifugal blower wheel is dynami-cally balanced for minimum vibration. The drain pan is insulated from the unit casing to prevent sweating.

A three-speed PSC fan motor is standard on all unit sizes. It is permanently lubricated and includes thermal overload protection.

Permanently Lubricated PSC Motor

The blower features a removable inlet ring to facilitate removal and servicing of the fan motor. For horizontal units, the blower assembly can be easily reconfigured in the field for side or straight discharge.

Easy Motor Removal

MS Product OptionsMS Product Options

HydroBank MS water source heat pumps offer numerous factory-installed options that can help mini-mize field labor and enhance system performance.

Extended Range, Geothermal UnitsAn extended-range or low-temperature option is avail-able on all heat pump units to allow heating operation down to 25F and cooling operation down to 40F entering fluid temperature. The option includes a freeze-stat water sensor, an insulated coaxial heat exchanger and insulated refrigerant piping.

Extended Range, Insulated Unit

Cupro-Nickel Heat ExchangerCupro-nickel tubes on the inner tube of the water-to-refrigerant heat exchanger provide additional corrosion protection in applications using well or city water.

Electronically Commutated Motors (ECM)Electronically Commutated Motors (ECM) offer a high level of efficiency at a variety of speeds, boosting the units EER. They are ideal in applications where high-efficiency filtration is required. The motor maintains the design airflow as filters load and the system static pressure increases. These constant-torque motors feature five pre-programmed torque settings that can be changed in the field to match design requirements. A soft-start, soft-stop feature reduces noise at unit startup and shutdown.

Constant-Torque ECM Motor

DDC ControllerA field-supplied DDC controller can be factory mounted and wired by Mammoth. This allows the engineer to specify a specific control manufacturer and achieve simple interface of the network system. See EPiC DDC Controls on page 13.

FreezestatA freezestat is available to sense the leaving water temperature. If the leaving water falls below 32F, the freezestat will open the safety lockout circuit and shut down the compressor. This option is beneficial on well water and city water applications where water tempera-tures can drop during the heating season.

Waterside Economizer CoilA waterside economizer coil option allows pre-cooling of the entering air to take advantage of cool loop water and to reduce compressor operation during cool weather. The kit includes a two-row water coil, 3-way diverting valve and an entering water thermostat to divert the water through the coil if the temperature is below set point.

Waterside Economizer Coil Option - Horizontal Units

Waterside Economizer Coil Option - Vertical Units


MS Product OptionsHot Gas Bypass ControlHot gas bypass prevents frosting of the evaporator coil during low-load conditions by keeping the compressor more fully-loaded. Hot, high-pressure refrigerant gas is diverted to the low-pressure suction side to help stabi-lize the system balance point. This option includes a hot gas bypass valve.

Hot Gas Bypass Option

Hot Gas ReheatHot gas reheat is the ideal solution to prevent over-cooling of the occupied space when the unit is in dehu-midification mode. Hot gas is used to reheat saturated air coming off the cooling coil without using an external heat source. Hot gas reheat coils are available on all unit sizes.

Hot Gas Reheat Option

Sound PackageA sound package option includes thick, 1 lb. den-sity fiberglass insulation on the entire unit, as well as the addition of a heavy dampening material over the entire bottom panel for reduced radiated sound levels.

Motorized Shutoff ValveTwo-way motorized control valves are ideal in systems that employ VFDs on the condenser water pumps. When the space temperature set point is satisfied, the unit shuts down and the valve closes. Pump power is thus greatly reduced at reduced flows, resulting in sig-nificant energy savings. A motorized valve is available to shut off the water flow through the unit when the com-pressor is off. The valve is a normally open, power-close type and will open in the event of power loss.

Motorized Valve Option

Four-Sided Filter RackA four-sided, 2-inch filter rack is available as a factory-installed option to accept high-efficiency filters such as Merv 8 or Merv 13. This option includes gaskets between the rack and the cabinet, and along the edge of the filter access door. The gaskets maintain the leakage rate below 4 CFM per square foot of filter area at 0.5 ESP. The filter door pivots open for easy filter removal and replacement.

Four-Sided Filter Rack Option

Dirty Filter SwitchA dirty filter switch informs the maintenance personnel to change filters. The switch senses the pressure drop across the filter.


ControlsControls

HP-5 Microprocessor Board The standard HP-5 microprocessor board provides the control interface between the room thermostat and the units compressors, reversing valves, fan, safety features and troubleshooting fault indicators. A remov-able terminal block makes controls hookup easy. For more information and a wiring diagram, see the HP-5 Operation and Maintenance Manual.

HP-5 Microprocessor Board

HP-5 Features and Benefits

Random start delays the startup of the unit 5 to 35 seconds after coming off from an unoccupied or shutdown cycle to prevent all of the units from start-ing at the same time.

Condensate overflow protection stops compres-sor operation if the drain pan sensor detects mois-ture at the top of the pan to prevent overflow due to clogged or slow-draining condensate piping

Compressor anti-short cycle protection prevents the compressor from being energized for 5 minutes after shutoff to limit compressor cycling and to ex-tend compressor life.

Shutdown allows the units to be shutoff with no compressor or fan operation in the event of an emer-gency. Shutdown is activated from a two-wire signal.

LED diagnostic display communicates the status of the unit to indicate normal operating mode, low voltage condition, high voltage condition, shutdown mode, high pressure/ low pressure switch fault, and condensate sensor.

High and low voltage protection shuts off the unit in the event the supply voltage is too high or too low to protect the internal components from damage.

Safety lockout prevents compressor operation if any of the following safety switches trip: high pres-sure/low pressure switch, condensate overflow pro-tection or optional freezestat. The unit can be reset from the wall thermostat or the main unit disconnect.

Auto reset-allows the unit to automatically reset itself three times within a 100 minute period; two-minute startup delay at initial startup; and at loss of power.

Fan interlock makes sure the fan is on when the compressor is on.

Lockout alarm sends a signal to the thermostat to illuminate an LED and close a set of dry contacts if any of the safety switches trip or if the unit is in shutdown mode due to a remote signal or to high/low voltage. Auxiliary dry contacts (set of normally-open and normally-closed) are activated when the compressor is on to operate a motorized valve.

When coupled with the proper thermostat the HP-5 board is also compatible with the following features:

o Night setback allows heating operation at a lower set point to maintain a minimum space temperature, which is activated by a two-wire signal. The fan will cycle with the compressor.

o Night setup allows cooling operation at a higher set point to maintain a maximum space temperature, which is activated by a two-wire signal. The fan will cycle with the compressor.

o Override allows night setback or setup modes to be deactivated for 2 hours while the unit resumes operation at its daytime set points. Override operation is activated by a push button on the wall thermostat.


ControlsEPiC DDC ControlsAs an option, Mammoth offers factory-programmed and unit-mounted EPiC DDC controllers for precise unit operation. They are factory programmed per the application, and have a 16-bit processor with 1MB Flash RAM and 4MB of battery-backed RAM.

The control programs, hand-held human-machine interface (HMI) files and editable set-points are stored on Flash RAM at the time of download or upon manual archive initiation.

In the event of a battery-backed memory loss, the program, HMI and archived set-points are refreshed from the archived data in Flash RAM. An on-board, battery-backed, real-time clock is included to allow for stand-alone operation scheduling.

The controllers include LED indicators for power, run, processor error for each control output, Building Man-agement System (BMS) communication transmit, and BMS communication receive.

EPiC controllers are capable of BMS network com-munication using either BACnet MSTP, Modbus RTU, or JCI N2 without an external gateway device from 9.6k to 76.8k Baud. They conform to BACnet Advanced Appli-cation Controller (B-ACC) Standard Device Profile as defined in ANSI/ASHRAE Standard 135-2012 (BACnet) Annex L, Protocol Revision 9.

EPiC controllers are also capable of BMS network com-munication using LonWorks (LonTalk) protocol with an optional LonCard to only include the required neuron chip. There are no requirements for LonCard programming.

A sensor/HMI network port allows 5 remote-mounted wall sensors and an HMI to be connected at the same time.

Application and Design Considerations Application and Design Considerations

What is a water source heat pump? A water source heat pump (WSHP) is a self-contained, packaged cooling-and-heating unit with a reversible refrigeration cycle. The refrigeration circuit is comprised of a compressor, a refrigerant-to-air heat exchanger (air coil), a refrigerant-to-water heat exchanger, an expansion device (thermal expansion valve), and a reversing valve. See the figure below.

Additionally, each water-source heat pump includes a blower to move air through the air-to-refrigerant heat exchanger, an air filter, unit-level controls, and possibly a few optional accessories depending on the application.

Water source heat pump systems can provide more energy efficient operation than most other HVAC systems on the market today. Water loop (cooling tower/boiler) water source heat pump systems also offer low installation costs. Ground loop (geothermal) systems, though more expensive to install, due to the cost of the ground loop,

provide exceptional efficiencies that usually recover the additional installation costs through lower energy costs.

How A Water Source Heat Pump WorksThe refrigerant reversing valve is the key difference between a heat pump and a standard air conditioning system. It allows a single refrigerant-to-air heat exchanger to provide both cooled air and heated air to the conditioned space.

In an air source heat pump system, a second refrig-erant-to-air heat exchanger is employed to remove heat from the refrigerant when the unit is in the cooling mode and to add heat to the system when the unit is in the heating mode. In a water source heat pump system, a refrigerant-to-water heat exchanger is employed for this purpose and the heat is transfered to a water loop.

A detailed explanation of how this system works in both the cooling mode and the heating mode is provided on the next page.

In the cooling mode, hot, high-pressure refrigerant gas is pumped from the compressor (upper right in the figure below) to the reversing valve (center) which diverts it to the refrigerant-to-water heat exchanger (lower right). Heat is transferred from the refrigerant gas to the loop fluid and the refrigerant condenses into a warm liquid. The warm liquid refrigerant then flows through the thermal expansion valve which reduces its pressure and temperature. The cold liquid refrig-erant then flows to the refrigerant-to-air heat exchanger (upper left) where it changes state from a liquid to a gas. Heat is absorbed from the air during this state change, and the cooled air is blown into the conditioned space (lower left). The refrig-erant gas then flows back to the reversing valve, which diverts it to the compressor to repeat the cycle.

Application and Design Considerations Water Source Heat Pump SystemsIn a typical WSHP system, each office, classroom or other defined space within the building is equipped with its own water source heat pump. Each heat pump inde-pendently satisfies the heating or cooling requirements for that space, regardless of the requirements of any other space.

Unlike conventional HVAC systems, this offers individual control and enhanced comfort in each conditioned space. Additional, dedicated outdoor air systems (DOAS) may be used to bring in outside air to meet fresh air requirements.

All of the water source heat pumps in the building are connected to a common water distribution loop. In addition to the heat pumps, this water loop will typically include a cooling tower, a boiler, a primary pump, a standby pump and a loop water temperature controller. In a ground loop (geothermal) system, the cooling tower and/or the boiler may not be needed, depending on the size of the ground loop and the local climate.

Water Loop (Boiler/Tower) SystemsWater loop systems, also called standard, conventional or boiler/tower systems, use a two pipe water circulating system to add, remove, or transfer rejected heat to other units throughout the building. A boiler/tower system uses a natural gas or electric boiler located in a mechanical equipment room to provide heat. A cooling tower is used to dissipate waste heat. This system typically has the lowest installed cost of the loop options.

Boiler/Tower System

Summer Cooling Mode

In the summer cooling mode, the water source heat pumps cool the space and reject heat to the water loop. If the loop temperature rises above the tower set point, the heat added to the water loop is rejected to the atmo-sphere through the cooling tower. See the Boiler/Tower System - Summer Cooling Mode figure below.

Winter Heating Mode

In the winter heating mode, the heat pumps heat the space using heat from the water loop and from the heat pump compressors heat of compression. The heat removed from the water loop is replenished by the boiler or by the ground loop. See the Boiler/Tower System - Winter Heating Mode figure on the next page.

Balanced Mode - A Major Advantage of Water Source Heat Pump Systems

Most modern buildings have a net cooling requirement year round in the interior core, irrespective of the out-side temperature. This is due to internal heat gains from people, office equipment and lighting. When this is the case, heat pumps in the interior core reject heat to the common water loop year round. In the winter, this heat is absorbed by those units on the building perimeter that are in heating mode. See the Boiler/Tower System - Balanced Mode figure below.

In effect, the system is moving energy around the building from where it is in excess to areas where it is needed. In many instances, the result is a balanced system where the heat generated in the interior space is sufficient to heat the perimeter space with neither the cooling tower nor the boiler operating. This is especially true during the spring or fall when the demand for heating or cooling is lower. This makes a water source heat pump system one of the most energy efficient systems on the market.

Application and Design Considerations Ground Loop (Geothermal) SystemsGround loop systems take advantage of the earths rela-tively constant temperature and use the ground, surface water or well water to absorb and eject heat from the water source heat pump fluid loop. During the summer, the heat pumps absorb heat from the building and store it in the ground. See the Geothermal System - Summer

Cooling Mode figure below. During the winter, they absorb heat from the ground and transfer it into the building. See the Geothermal System - Winter Heating Mode figure below.

During the fall and spring, some water source heat pumps are typically absorbing heat from the water loop while others are rejecting it.

Application and Design Considerations Ground Loop System TypesIn a geothermal system, lengths of high-density poly-ethylene pipe are typically buried in the earth either in vertical bore holes or in horizontal trenches. Fluid from the distribution loop inside the building circulates through these pipes and either rejects heat to the earth or absorbs heat from it. Systems may also be config-ured to reject or absorb heat from ground water or a pond, lake or stream.

Horizontal Closed-Loop Systems

Horizontal closed-loop geothermal systems use a series of parallel loops installed in trenches approximately 5 feet below the ground. The piping may be installed using a four-pipe or a six-pipe design. This system is well suited for applications where physical space is available or where vertical bore drilling is prohibitive. Between 1,500 and 2,500 square feet of space per ton of cooling is required.

Horizontal Closed-Loop System

Vertical Closed-Loop Systems

Vertical closed-loop geothermal systems are ideal for projects with minimum available space. Vertical bore holes are drilled 150 to 500 feet deep depending on building design considerations. Plastic polyethylene U-bend loops are inserted into the holes and are con-nected in a parallel, reverse-return arrangement to allow fluid to circulate evenly throughout the bore field. Depending on the design, loop temperatures range from 37F to 95F.

Vertical Closed-Loop System

Surface Water Closed-Loop Systems

Surface water, closed loop geothermal systems use a polyethylene loop or plate-type heat exchangers installed directly in a lake or pond near the building. This is an extremely efficient and cost effective system. Care must be taken to ensure the body of water will meet building loads. Debris problems from flooding or the need for public access may limit the use of this application.

Surface Water Closed-Loop System


Application and Design Considerations Open-Loop Well Water Systems

Open-loop systems use ground water to remove or add heat to the water loop. They are typically used in regions where ground water is plentiful. Water is typi-cally extracted and discharged back to the aquifer. The major benefit is the constant well water temperature which provides very efficient operation at a relatively low installed cost. An isolation heat exchanger can be added to reduce maintenance costs and conserve water.

This system usually has supply wells and return wells. Some states have requirements regarding the depth of return wells. Check local regulations. Water should be tested and strainers are typically required as poor water quality can increase heat exchanger scaling and suspended solids can lead to heat exchanger erosion.

Open-Loop Well Water System

Hybrid Geothermal SystemsIn a traditionally designed ground-source heat pump system, no cooling tower is necessary. In addition, if the heat pumps can satisfy all building heating require-ments, no boiler is necessary, saving initial cost and floor space. That being said, there are applications where the addition of a cooling tower or boiler to the system makes economic sense, since it can significantly reduce the size requirements for the ground loop field.

Hybrid System for Southern Climates

In southern climates with long, hot summers and mild winters, the size of the ground loop field required to eject heat to the ground can be reduced considerably by adding a cooling tower to the system. The cooling tower provides supplemental cooling to the system on hot summer days. See the Hybrid System with Cooling Tower figure below.

Application and Design Considerations Hybrid System for Northern Climates

In northern climates with short summers and long, cold winters, the size of the ground loop field required to absorb heat from the ground can be reduced con-siderably by adding a boiler to the system. The boiler

provides supplemental heating to the system on cold winter days. The ground loop must be bypassed during boiler operation. See the Hybrid System with Boiler figure below.

Horizontal Unit InstallationHorizontal Unit Installation

Mounting Horizontal units are typically suspended from the ceiling using four threaded rods (supplied by others). The rods should be attached to building structural members. See the Suggested Horizontal Unit Mounting figure below for a typical mounting configuration. The rods are fas-tened to each corner of the unit through factory-provided mounting brackets and rubber isolators. See the instal-lation and operation manual provided with the unit for detailed instructions.

Do not locate units above noise-sensitive areas such as offices, meeting rooms, and classrooms. If possible, avoid locations above areas where there is considerable traffic as service time may be limited during occupied hours. Placing units above hallways is a typical location in schools to avoid potential noise problems, with supply and return air ducted to adjacent classrooms. Such locations may limit service time during school hours.

Suggested Horizontal Unit Mounting

Suggested Service ClearancesUnits should be positioned to provide clearance to per-form routine maintenance or service, including easy filter replacement. The figure to the right above shows sug-gested clearances. Any additional clearances would be beneficial, but are not always necessary. For information on filter sizes, see Table 8: Physical Data: Horizontal Units on page 46.

The requirements on any specific unit may increase or decrease depending on factors such as electrical instal-lation codes. If return air is not ducted, it is important to provide enough clearance for adequate airflow.

PipingUnits are usually connected to the water loop supply and return piping using a reverse return arrangement. A flow control device is included to maintain proper water flow for each zone. A flexible, high-pressure hose should be used to connect the system piping to the unit to simplify installation and provide sound attenuation. One end of the hose should have a swivel fitting for removal of the unit for servicing.

The system piping design should include supply and return shutoff valves to facilitate the removal of one unit for servicing or replacement while the system continues to operate. The return valve may be used for water flow balancing. It will typically have a memory stop to allow it to adjust to the proper position for the required flow upon reopening. Fixed flow valves can be used to replace the memory-type valve.

Providing pressure and temperature ports allows mea-surement of these values during operation.

Vented PVC Condensate Trap by Others


Horizontal Unit InstallationCondensate Drain Piping A flush-mounted, female thread, condensate connec-tion is provided on the cabinet. See Horizontal Units Dimensional Data on page 47 for location and sizing. Condensate piping can be PVC, steel or copper. PVC typically eliminates the need to insulate the pipe to prevent sweating.

A condensate trap that has a depth of at least 3 inches or 2.5 times the the expected negative static pressure of the unit must be provided. The condensate pipe run must slope down from the unit at least 1/8 inch per foot. The trap may be constructed of PVC, copper or steel. Piping should be vented. See Vented PVC Condensate Trap by Others on page 22 for an example. Refer to local codes for the correct condensate piping to drains.

Ductwork and Sound Attenuation Horizontal, ceiling-mounted heat pumps virtually always have discharge ductwork attached to the unit. A collar is provided on the discharge to facilitate attachment to the ductwork. Ductwork should conform to industry standards as listed in the ASHRAE Systems Guide.

Good design practice requires a flexible connector between the collar and transition to the main duct system. This connector attenuates sound from the unit, especially fan sound, and simplifies unit removal.

Ductwork should be lined with an acoustic, thermal insulation that is a minimum of inch thick. For sensi-tive installations, use 1-inch insulation a minimum of five to 10 feet prior to each diffuser. For applications that are

especially acoustically sensitive, consider an acoustic kit that includes additional unit lining and dampening mate-rial beneath the entire unit.

Ducted returns may be used on horizontal units for acoustically sensitive applications. Return ducting should extend at least 12 inches from the coil before transitioning to provide even air distribution across the coil. A flexible connector should be used to connect the unit to the return ducting to attenuate unit sound levels and allow ease of unit removal. The filter section is sup-plied with a bracket to accommodate return ductwork.

Changes in duct direction such as tees, elbows, and internal devices such as dampers that create airflow tur-bulence can increase acoustic problems. Minimize these items where possible. Placing a straight run of duct about the width between fittings will decrease turbulence and associated noise. Diffusers located in the bottom of a trunk duct pose acoustical problems. Volume control dampers should be placed well upstream of any air outlets.

Applications that have a single duct discharge, such as hotels, should limit the velocity to a maximum of 600 fpm. These applications have a short run of discharge duct that must be fully lined with an elbow without turning vanes. Return air grilles should be located low on the sidewall and routed up to the ceiling plenum. An attenuator placed at the return opening will provide added acoustical protection.

LocationVertical units are intended for installation in a small mechanical room or closet. HydroBank MS unit design minimizes sound levels to allow installation adjacent to occupied spaces. The return may be ducted or non-ducted and is typically located ninety degrees to the closet door with access panels facing the door as shown in the figure below.

Suggested Vertical Unit Mounting

Suggested Service ClearancesLocate units for ease of filter and access panel removal. The closet door should extend past the end of the unit to allow for easy filter removal. A field-supplied line voltage disconnect is required for branch circuit protection.

The figure to the right above shows minimum sug-gested clearances. Any additional clearances would be beneficial, but not always necessary. Units need to be accessed from the front for filter removal and for access to the electrical panel, blower motor, air coil and com-pressor compartment. For information on filter sizes, see Table 11: Physical Data: Vertical Units on page 74. The requirements on any specific unit may increase or be reduced depending on several factors such as maintenance requirements and mechanical or electrical installation codes. If return air is not ducted, enough clearance will be required to provide for adequate airflow.

Vented PVC Drain Piping (Internally Trapped), Flexible Braided Hose Water Piping By Others


Vertical Unit Installation Condensate Drain Piping Condensate lines on vertical units are internally trapped. A 3/4 FPT, flush-mounted, condensate drain connection is provided on the outside of the cabinet. Condensate piping can be PVC, steel or copper. PVC typically elimi-nates the need to insulate the pipe to prevent sweating. Piping should be vented. Refer to local codes for the correct condensate piping to drains.

Ductwork and Sound Attenuation Vertical unit discharge ductwork should include a non-insulated transition from the unit connection to a flexible connector at the full duct size. It should also include a short run of duct and an elbow internally lined with insu-lation but without turning vanes. The main duct may tee into branch circuits with discharge diffusers. Ductwork should conform to industry standards as listed in the ASHRAE Systems Guide.

Vertical unit return air is typically brought in through a grille in the closet door. The door should be located ninety degrees from the unit return to eliminate any line of sight. For non-ducted applications, a clearance in front of the unit of at least 12 is suggested to provide even air distribution across the air coil.

Return air may also be brought in through a grille and ducted to the unit. This ductwork should be internally lined with acoustic insulation and include a flexible con-nector at the unit. Sound attenuation is particularly crit-ical at the unit return. Return ducting will likely increase the required width of the closet. The filter section on all units is supplied with a bracket to accommodate return ductwork.

Ductwork should be lined with an acoustic, thermal insulation that is a minimum of inch thick. For sensi-tive installations, use 1-inch insulation a minimum of five to 10 feet prior to each diffuser. For applications that are especially acoustically sensitive, consider an acoustic kit that includes additional unit lining and dampening mate-rial beneath the entire unit.

Unit Selection ProceduresUnit Selection Procedures

Mammoth HydroBank Select Software for Water Source Heat Pumps can be used to provide fast, accurate and complete selections of all water source heat pump products. It is recommended that you always use the HydroBank Select software to correctly match a unit to the actual zone loads and airflow requirements. This software is available from your local Mammoth repre-sentative.

If situations prevent you from immediately accessing HydroBank Select software, use the catalog selection procedure below and confirm results with the selection software at a later date.

Unit Selection Using Catalog DataDuring HVAC system design, a unit may need to be quickly selected or considered without the availability of the HydroBank Select Software. The following catalog selection procedures can quickly match a unit to the zone requirements.

Boiler / Cooling Tower Application

In this example we are using 80F dry bulb / 67F wet bulb entering air conditions for cooling and 70F entering air conditions for heating. Entering fluid tem-peratures for this Boiler / Tower application are 90F (32.2C) for cooling and 70F (21.1C) for heating. Existing zone load requirements are:

Total Cooling Load = 33,600 BTUH Sensible Cooling Load = 25,300 BTUHTotal Heating Load = 26,100 BTUH Design Air Flow = 1,200 CFMEntering Air Temp - Cooling = 80F DB/67F WBEntering Air Temp - Heating = 70F DBEntering Fluid Temp - Cooling= 90FEntering Fluid Temp - Heating= 70FWater Flow (Based on Cooling) = 10.8 GPMCabinet configuration Horizontal

First establish whether this application is commercial or multifamily. Commercial buildings are usually cooling dominant so the initial unit selection should match the cooling sensible load. If it is a multifamily application, you may need to match the heating requirement which, in some cases, could be the dominant load.

Start by selecting a unit with approximately 36,000 BTUH of cooling. In this case the Mammoth horizontal MSH1036 (page 37) will supply the following capacities at 1200 CFM airflow and 10.8 GPM water flow:

Geothermal Ground Loop Application

The following example illustrates the same zone in a geothermal application. Entering fluid temperatures for geothermal systems can be as high as 110F and as low as 20F. Design entering fluid temperatures for heating and cooling are to be determined by the design engineer and are usually based on location and /or ground temperatures. Typical design entering fluid tem-peratures are 90F for cooling (summer) and 40F for heating (winter). As a rule of thumb, the design entering fluid temperature for cooling is 10F below the maximum outdoor air temperature, and the design entering fluid temperature for heating is 40F above the minimum outdoor air temperature. Water flow rates are typically 2.5 to 3.0 GPM per ton and the use of antifreeze is recommended in most northern applications.

Like the earlier Boiler / Tower example, we are using entering air temperatures of 80F dry bulb / 67F wet bulb entering air conditions for cooling and 70F entering air conditions for heating. It is determined that the highest entering water temperatures for the ground loop design will be 90F for cooling with expected entering water temperatures for heating at 35F.

Antifreeze will be used in the loop field so capacity correction factors will be used and will be based on the type of antifreeze and concentration. The design air flow will be 95% of catalog data and will also require use of correction factors for final capacity output.


Unit Selection ProceduresZone load requirements are:

Total Cooling Load = 33,600 BTUH Sensible Cooling Load = 25,300 BTUHTotal Heating Load = 24,300 BTUH Design Air Flow = 1,140 CFMEntering Air Temp - Cooling = 80F DB/67F WBEntering Air Temp - Heating = 70F DBEntering Fluid Temp, Cooling = 90FEntering Fluid Temp, Heating = 35FWater Flow (Based on Cooling) = 10.8 GPMCabinet configuration Horizontal

Start by selecting a unit with approximately 36,000 BTUH of cooling. In this case, the Mammoth horizontal MSH1036 (page 37) will supply the following capacities at 1200 CFM airflow and 10.8 GPM water flow. The heating capacity data (page 37) is 26,400 BTUH for 40F and 23,400 BTUH at 30F. The heating capacity at 35F is exactly between the two numbers and is 24,900 BTUH.

Next, determine reduced capacity based on the airflow and antifreeze correction factors available on 28 of this catalog. In this case the engineer is using 20% propylene glycol (with a sufficient inhibitor package) and airflow is 95% of catalog CFM.

Glycol correction factor for 20% propylene glycol is:

0.987 (Cooling and heating)

Airflow correction factor for 1,140 CFM (95% of catalog) is:

0.993 Total Cooling 0.974 Sensible Cooling 0.990 Heating

Corrected Heating Capacity =

24,900 0.99 0.987 = 24,330 BTUH

Corrected CFM = 1,140 CFM

Since the sensible cooling capacity is slightly less than the design load, judgment must be used to determine if the next larger capacity unit is necessary. Oversized equipment should be avoided to minimize the potential for humidity and comfort issues.Recommended selection = Mammoth MSH1036 Horizontal Cabinet

Geothermal loop software programs are available to help determine the size of the loop field based on:

Desired entering water temperatures for the system. These are usually the same temperatures that are used in this unit selection procedure.

Specific loop field design criteria based on acreage available, loop field spacing, vertical bore depth, piping selected, flow rates, circulated heat transfer fluid, and local formation geology for the loop which produces specific min./max. loop temperatures for the unit selection.
