ChassisThe concept of individualized room conditioning began many years ago with the Type K conditioner. Over the years this design has become the benchmark for quality and reliability. Continual research and product improvement has allowed McQuay to re-main the leader in the sectionalized unit market. Recent design changes have further enhanced the efficiency and durability of the Type K chassis. Many important features have been developed. Those features relevant to this design change are listed below.

CompressorThe power plant for the Type K is a high efficiency rotary com-pressor. It has a proven track record of efficiency and reliability to insure low cost, and continuous service for many years. In addition to its high efficiency, this compressor is protected against thermal overload and is precision balanced for quiet operation.

HeatTransferSurfaceAn advanced coil design is employed in all Type K units. The copper tubes have an internal rifled surface to increase the heat transfer capabilities of the refrigerant. Aluminum fins are mechani-cally bonded to the copper tubes to insure positive heat transfer. The fins are lanced to increase the air turbulence making the coil extremely efficient.

Figure 5. Condensate Disposal

Heavy-DutyConstructionThe Type K cooling chassis is constructed of heavy-gauge steel for unsurpassed durability. It is insulated with a waterproof material to prevent sweating. The dense insulation, combined with heavy-gauge steel, results in a unit with very low sound levels. The design of the plug-in device connections allows for quick and easy power disconnection without the use of tools. A con-venient amp connector is used to transfer power to the cooling chassis from the control box. The amp connector eliminates hard-wired connections that hinder chassis removal for sched-uled maintenance. All unit sizes utilize the same amp connector to facilitate interchangeability of spare chassis.

High Efficiency Condensing SectionThe outdoor condenser section uses a reliable PSC motor to drive an efficient centrifugal fan. Besides being quiet, the centrifugal fan is used to dispose of unwanted condensate generated during the cooling cycle. Condensate draining from the evaporator coil is atomized and entrained by the condenser blower airstream, re-evaporated on the hot condenser coil where it escapes to the outside as vapor. No slinger rings are used and the condensate never comes in contact with the outdoor blower wheel(s). Re-evaporation also lowers condenser temperature and pressure to increase overall cooing efficiency.

The concept of individualized room conditioning began many years ago with the Type K conditioner. Over the years this design has become the benchmark for quality and reliability. Continual research and product improvement has allowed McQuay to re-main the leader in the sectionalized unit market. Recent design changes have further enhanced the efficiency and durability of the Type K chassis. Many important features have been developed. Those features relevant to this design change are listed below.

• “Fan”Option(Sizes007-014) A “fan only” function is provided to enable fan operation for

improved circulation and increased air filtration. The dual speed fan is controlled by a unit mounted fan speed rocker switch for user convenience.

• RemoteControl(Sizes007-014Only) The Type K unit can be connected to a wall thermostat for

remote control operation. A variety of thermostats are compat-ible with this unit including many programmable varieties.

• MultipleUnitControl(Sizes007-014Only) Large conference rooms and hallways can be conditioned by

many units using a single thermostat. One unit is designated as a control unit and up to seven units can be connected to the control unit for synchronized operation. Any unit can be designated as the control unit with only minor field wir-ing modifications to make the other units into the controlled units.

• Constant/CycleFanSwitch(Sizes007-014Only) A constant/cycle fan switch is provided in the Type K unit

(sizes 007–014) allowing the fan to run continuously or cycle with the thermostat. This switch is located on the control box and is concealed behind the front panel to prevent unauthor-ized tampering. When the switch is placed in the “cycle” mode, the indoor fan will energize when there is a call for heating, cooling, or fan. Placed in the “constant” mode, the fan will run continuously. Constant fan offers better air circulation and improved fan filtration compared with the cycle option. The large units, sizes 019–022, are only available with constant fan.

HeatSectionThere are three types of heat sections available for the Type K units: hot water, steam, and electric resistance. Like the cooling chassis, these sections are built to last. There are many unique features of the Type K heating section that have contributed to its popularity. The heat section is independent of the cooling chassis. Unique features of the Type K heat section are listed below.

• QuietOperation Large forward curved fans are used on the indoor side to

provide efficient comfort conditioning with low sound levels. The blow-through design and heavy-gauge sheet metal pro-vide a high degree of attenuation not found in draw-through designs.

• High Efficiency Motors High efficiency, low sound producing PSC motors are utilized

by Type K units. All motors employ extended lube lines for periodic lubrication during scheduled maintenance.

• FactoryInstalledValve(Sizes007-014Only) Hot water and steam heat sections are furnished with a factory

installed valve. Normally open, 2-way line voltage valves are supplied for hot water coils and normally closed �-way line voltage valves are supplied on steam valves. On sizes 019 and 022, valves are furnished but not installed.


RoomCabinetsThe room cabinet is designed to complement any room decor. The heavy-gauge steel is coated with an attractive appliance grade powder paint which is then oven baked for durability. An adjustable kickplate is provided to accommodate various wall opening locations. The standard adjustment is +/-1". The room cabinet is designed to completely encompass the unit and conceal any piping or electrical connections from the room occupant. The front panel is removable for service access of filters, valves or electrical connections. Hidden latches are supplied to prevent unauthorized personnel from opening the front panel. On sizes 007-014 the discharge grille of the room cabinet is equipped with individual four-way adjustable steel grilles. This feature allows the owner to force the air in various directions to prevent stagnation. An extruded aluminum discharge grille is standard on the large units (019–0��) and optional for sizes 007–014. This grille is available to further enhance the unit's appearance. The Type K room cabinet is factory furnished in a variety of depths to accommodate every wall thickness. The entire cabinet is powder coated with an epoxy Antique Ivory finish and comes complete with a handsome Oxford Brown reveal around the perimeter for accent.

WallBoxesThe Type K wall box is made from heavy-gauge steel and coated with a tough epoxy powdered paint for corrosion protection. The wall box is designed to be placed into the wall during construc-tion to assure a snug fit. The standard wall box can accommodate a wall depth of 135⁄8'' without modifications. It can be easily adapted to deeper walls with minor factory modifications. Wall box/sleeve extensions are available for field installation through your McQuay sales representative. The dimensions of the wall box have not changed since the unit was originally designed in 1958. Therefore, if the existing wall box is in good condition, the old chassis or heat section can be easily replaced without additional wall modifications. Consequently, the unit can be replaced to provide high efficiency operation with minimal disruption or downtime.

Filtration The filter is a permanent, cleanable wire mesh filter that is designed to provide superior dust collecting abilities.

OutdoorLouversThe standard louver is a one-piece, extruded architectural alu-minum type with a natural finish. Louvers by others are acceptable as long as they meet fac-tory specifications. They must have a minimum free area of 70% or a pressure drop not exceeding 0.05 in. w.g. at 300 fpm face velocity, and a blade design that will not cause recirculation of condenser air. Free area is defined by ASHRAE as the minimum area of the openings in an air inlet or outlet through which air can pass. Application of special louvers or building facade treatment that may affect normal operation of the unit, or restrict free air discharge of condenser airflow, should be referred to the Application Engineering Department for evaluation. A louver design that restricts the passage of condenser air or causes condenser air to be recirculated will dramatically alter the perfor-mance of the unit. Unit capacity and efficiency may be decreased and fan motor and compressor life may be shortened. If the louver does not meet the above outlined requirements or is only marginally acceptable, a drawing should be sent to the Incremental Application Engineering Department for evaluation. If acceptance still cannot be determined by the drawing, then a sample of the proposed louver should be sent to McQuay for testing and certification. The sample sent for testing must match the wall opening for the unit selected.

SampleCalculation:

HeatingCapacitiesatNonstandardConditionsThe hydronic coil can be used with either hot water or steam. To determine the correction factor at nonstandard conditions us-ing hot water, use Figure 17. Follow the known flow rate to the corresponding EWT curve and read to the left to determine the heating correction factor. Apply this percentage to the standard ratings shown on page 5.

Figure 17. Hot Water Heating Correction Factor Curve

For conditions at temperatures other than 65oF, determine the correction factor using Figure 18. From a known entering air temperature, follow up to the line and then go left to determine the correct percentage. Apply this percentage to Figure 17 (when using hot water) before plotting the heating correction factor.

Figure 18. Heating Capacity Correction Factor Curve

For ratings at nonstandard conditions using steam, refer to Figure 19. Follow the known steam pressure to the curve cor-responding to the known entering air temperature. Read down to determine the correction factor. Multiply this number by the standard rating found on page 5 to determine the rating at non-standard conditions.

Figure 19. Steam Heating Correction Factors

To determine the water pressure drop (WPD) at nonstandard flow rates, enter known gpm on Figure 20. Follow to conditioner line and read left for appropriate WPD. To find the WPD of the valve, repeat procedure. Add the WPD of the valve and the WPD of the conditioner to get the total.

ling unit. The controlling unit's transformer handles 50 VA power draw. Each controlling unit has up to 5.6 VA power draw. Up to seven controlled units can be connected to the controlling unit without danger of overheating the main transformer, although it is unlikely this many controlled units will be connected to one controlling unit.

When using remote mounted thermostats, it is often necessary to control more than one Type K unit from a single thermostat. Figure 33 illustrates schematically how a controlling and con-trolled unit(s) are connected to a single thermostat. Note that the jumper between terminals C and A of the control unit is removed. This takes the controlling unit's transformer out of the circuit allowing it to duplicate the operation of the control-

Figure 31. Manual Changeover (MCO) Figure 32. Automatic Changeover (ACO)Thermostat (106069001) Thermostat (105570901)

Type K units can be controlled by a remote mounted, low volt-age wall thermostat. Several variations of low voltage wall thermostats are available. The most common types used are

manual changeover and automatic changeover. Figures 31 and 3� illustrate the typical wiring schematics for proper connection of the Type K series units to the wall thermostat.

Figure 34. Guest Room Control

GuestRoomControl(GRC)This additional control, widely used by hotel/motel opera-tions, is provided for use on Type K equipment. GRC allows the owner to substantially reduce energy consumption by de-energizing the equipment in unoccupied spaces. The Incremental units are wired to a central location, usually the front desk, where they are controlled by a toggle switch in a control panel (supplied by others). The units remain de-energized until the room becomes occupied, at which time the clerk can energize the equipment from the front desk (see Figure 34).

NightSetbackControl(NSB)Additional savings can be achieved through use of the night set-back control (NSB). NSB incorporates an additional unit mounted thermostat to maintain a minimum, predetermined room tempera-ture. The temperature is set at the factory to 55oF (13oC). This setpoint is adjustable by the owner to activate anywhere between 45oF and 55oF (7oC and 13oC). If the room temperature drops below the owner selected minimum temperature, the heat cycle

EnergySavingOptions

and indoor fan are energized until the night setback thermostat is satisfied. NSB overrides the unit control even if it is placed in the “stop” position or inadvertently left in the “cool” position.

OutdoorAirDampersType K units are furnished with an automatic outdoor air damper as standard. The automatic damper is wired in parallel to the indoor fan safety. If the unit is placed in the “cycle” mode, the fan and damper cycle as the thermostat cycles. If the unit is placed in the “constant” mode, the fan runs continuously and the damper is always open. The automatic damper feature can be overridden during NSB if the unit is so equipped. This prevents cold air from entering the occupied space when the unit is simply bringing the room back to the night setback temperature. Since NSB is used when the room is unoccupied, there is no reason to introduce outside air during this cycle.

Type K Model Engineering Guide Specifications

CoolingChassisCooling chassis shall be slide-in, plug-in with a self-contained,

hermetically sealed refrigerant circuit. All chassis sheet metal parts shall be constructed of heavy-gauge steel. The chassis shall be insulated with a waterproof material to prevent sweating and reduce sound levels.

The cooling chassis shall consist of the following compo-nents:

Vibration isolated, permanent split capacitor, rotary-type compressor with built in thermal overload; rifled copper tubed evaporator (indoor) and condenser (outdoor) coils with high ef-ficiency raised lance aluminum plate fins mechanically expanded to the tubes for maximum heat transfer and a capillary restrictor type refrigerant metering device supplemented with a constant pressure automatic expansion valve. Coils shall be factory tested at 300 psig.

Condenser airflow system shall consist of a separate, single speed PSC motor with an aluminum blade centrifugal fan. The motor shall be totally enclosed and permanently lubricated with external oilers for prolonged life. The fan shall be forward curved and statically and dynamically balanced to provide for quiet and smooth operation.

The cooling chassis shall also be furnished with a positive closing, automatic, motorized outdoor air damper that opens whenever the indoor fan is energized, except during night set-back operation. A toggle switch shall be provided for manual override of the damper.

During the cooling cycle, the compressor and both the out-door/condenser and indoor/evaporator fan motors shall be ener-gized. Condensation accumulated in the indoor/evaporator drain pan shall be drained into the outdoor section of the unit where it is to be completely removed by evaporation. Evaporation shall be accomplished by uniformly distributing the condensate over the condenser coil via airflow generated by the outdoor/condenser fan. Condensate shall not come in contact with fan or fan motor. Slinger rings and propeller fans are not an acceptable solution for condensate removal.

HeatingSectionThe heat section shall be separate from the cooling chassis

and shall incorporate an indoor/evaporator fan assembly. This assembly shall consist of two centrifugal fans that are forward curved and constructed out of aluminum with steel hubs and directly connected to a two-speed motor. Fans shall be stati-cally and dynamically balanced to provide for quiet and smooth operation. The indoor/evaporator fan motor shall be two speed,
