Energy indices

Energy indices ESEER and IPLV

Increasingly closer attention is being paid towards the power consumption of air-conditioning

equipment. Indices have been introduced that also consider usage in part load conditions when the

external air temperature is lower than the rated value and when the separation stages of the cooling

compressors are used. The valuation index adopted in the United States is called IPLV (Integrated

Part Load Value) and is defined in the regulations issued by ARI (American Refrigeration Institute).

IPLV ARI

= (1*EER100%

+ 42*EER75%

+ 45*EER50%

+ 12*EER25%

) /100 ARI Standard

where:

EER100%

, EER75%

, EER50%

and EER25%

are the efficiencies of the chiller in the various load conditions (100% - 75% - 50% and

25% respectively), calculated in the external air temperature conditions shown below. The temperature of the water leavingthe evaporator is considered constant at 6.7°C in all load conditions, with a delta of 5°C in the full load condition.

The multipliers 1, 42, 45 and 12 are the cooling performance coefficients in various load conditions statistically calculated by

ARI an the basis of surveys conducted, for various types of buildings and operating conditions, in 29 Amerian cities.

In normal European applications it is difficult to think of a chiller working at an external air temperature lower than 20°C. Air-

conditioning is never used to this extent; design and legislative constraints tend to reduce power consumption and encourage

the adoption of systems based on the direct or indirect use of external air wherever possible (FreeCooling).

Concerning the ESEER index in Europe, reference is made to a proposed EECCAC (Energy Efficiency and Certification of

Central Air Conditioner).

ESEER = (3*EER100%

+ 33*EER75%

+ 41*EER50%

+ 23*EER25%

Using the energy indices

After estimating the total cooling capacity required by the system in the

summer mode (in kWh), we can calculate seasonal electricity

consumption (in kWh) using the following formula:

Power absorbed = Power requested / Index of efficiency

This method allows us to make comparisons between similar or

equivalent systems using the same reference unit.

High efficiency series

This new series of units combines elevated efficiency rates (EER) with the use of R134a refrigerant.

The excellent level of performance was achieved thanks to the accurate sizing of all internal components in order to fully

exploit the characteristics of the ecological refrigerant used. Special attention was paid to all the heat exchange surfaces,

fans and compressors.

The newly designed condenser coils with special construction features have larger surfaces, as do the new asymmetrical

evaporators with improved and more efficient refrigerant distribution both in the liquid and steam phases.

The fans with elevated unit efficiency are suitably adjusted to optimise air flow to the condensing section and guarantee

maximum silent-running in all operating conditions.

The new screw compressors are specially designed for R134a refrigerant.

The continual adjustment feature constantly modulates the capacity of each compressor between 100% and 50% of its

potential. This adjustment mode also allows the exact power required by the system to be instantaneously delivered and

precisely adapted to load variations. This in turn reduces the number of start-ups and consequently improves reliability. The

accompanying unit adjustment feature, based on evaporator outlet water temperature control, guarantees extremely small

variations compared with the set point.

The advantages of the continual adjustment of individual compressors are enhanced with the use of electronic thermostat

valves (optional for the entire range). Their precision and rapidity of response optimise load variations and allow stable

conditions to be achieved in a very short time, even when operating in the part load mode. The accurate sizing of the system

combined with this series of units offers considerable energy saving and consequently significant reductions in running

costs.

Air-cooled water chillers

Air-cooled water chiller with axial fans for outdoor installation. The unit is supplied with anti-freeze oil and refrigerant and

has been factory tested. On-site installation therefore just involves making connections to the mains power and water

supplies.

Unit charged with R134a refrigerant.

STANDARD UNIT COMPOSITION

Supporting frame

Base and frame in thick hot-galvanised shaped sheet steel. All parts polyesters-painted.

Screw compressors

Semi-hermetic screw-compressors with 2 five and six-lobe rotors. The fivelobe rotor is directly splined onto the 2-pole motor

(2,950 rpm) without the use of overgears. Compression occurs five times every motor turn and the gas therefore discharges

continuously without the typical throbbing common to reciprocating compressors. Leading-edge numerical control machines

were used to make the rotors and machine the bearing seats. Compressor cooling power is continuously modulated from

100 to 50%. In addition to the standard no-load starting feature, the motors are fitted with electric starting devices which limit

the power absorbed during the compressor starting phase. A check valve on the coolant delivery line prevents the rotor from

reversing after stopping. Special maintenance-free bearings allow very long work cycles. Lubrication is forced, without the

use of an oil pump. The high efficiency built-in oil separator ensures the constant presence of oil in the compressor. The

rotors are dynamically balanced to ensure that the vibrations common to reciprocating compressors do not occur. The lack

of vibrations and the absence of delicate intake and delivery valves, in addition to very fine manufacturing tolerances,

sophisticated quality controls during the production process and a limited number of moving parts, guarantee quiet and

highly reliable operation. Each compressor is fitted with manual-reset motor thermal protection, delivery gas temperature

control, an oil level float, an oil level sight-glass and an electric resistance for heating the oil when the compressor is

stopped.

Water-refrigerant heat exchanger

Direct expansion heat exchanger type with asymmetric refrigerant paths to maintain the correct refrigerant velocity inside

the tubes during both liquid and gaseous phases. The steel shell is insulated with a closed-cell anticondensation lining. The

copper pipes are internally grooved so as to improve the heat exchange. The pipes are mechanically expanded onto thetube plate ends. An antifreeze electric heater prevents the formation of ice inside the casing of the exchanger when the unit

is not operating but connected to the electrical supply. Differential pressure switch for controlling the water flow is fitted

standard.

Refrigerant-air heat exchanger

Aluminium fins and copper tubes type heat exchanger. The aluminium fins are correctly spaced to guarantee the best heat

exchange efficiency. The lower part of the exchanger functions as a sub-cooling circuit thus increasing the cooling capacity.

Fans

Axial electric fans, protected to IP 54, with external rotor and profiled diecast aluminium blades. Housed in aerodynamic

hoods complete with safety grille. 6-pole electric motor with built-in thermal protection. Pressure switch condensing control

by sequentially excluding certain fans.

Refrigerant circuit

Main components of the refrigerant circuit:

- compressor discharge check valve,

- compressor discharge shut-off valve,

- liquid line shut-off valve,

- liquid line solenoid valve,

- dryer filter with replaceable cartridge,

- refrigerant line sight glass with humidity indicator,

- externally equalised thermostatic valve,

- high pressure safety valve,

- low pressure safety valve,

- high and low pressure transducers

- high pressure switches,

- differential pressure switch for water

Electric power and control panel

Electric power and control panel, built to EN 60204-1/EC 204-1

standards, complete with:

- control circuit transformer,

- general door lock isolator,

- power circuit with bar distribution system,

- fuses and contactors for compressors and fans,

- terminals for cumulative alarm block (BCA),

- remote ON/OFF terminals,

- spring-type control circuit terminal board,

- electric panel for outdoor installation,

- electronic controller.

- phase sequence relay

Basic model

Unit without heat recovery.

Model with partial heat recovery (D)

Air cooled chiller with partial heat recovery. Compared with the basic configuration, this version features an additional

refrigerant/water heat exchanger on the gas delivery line. This heat exchanger, fitted in series before the traditional cooling

circuit condenser, is large enough to recover heat for the production of medium-to-high temperature water for domestic hot

water and the like. The heating capacity of the heat recovery circuit is approximately equal to the power input of the

compressor. Each exchanger is fitted standard with an antifreeze heater


7/36


5

Model with heat recovery (R)

Air cooled chiller with total heat recovery. Compared with the basic configuration, this version features an additional refrigerant/

water heat exchanger on the gas delivery line. This heat exchanger, fitted in parallel with the traditional cooling circuit

condenser, is large enough to recover heat for the production of domestic hot water and the like. The heating capacity of the

heat recovery circuit is approximately equal to the cooling power plus the power input of the compressors. Each exchanger

is fitted standard with an antifreeze heater

Cooling Capacity

In order to improve the cooling capacity and

efficiency of the unit, Climaveneta makes the

following adjustment to the unit on the basis of

standard machines:

Enlarge the evaporator of the unit, adopt

closely arranged small tubes, further enlarge

the heat exchanger, and adopt dual-face

rippled tube.

Enlarge the condenser of the unit, change

the direction of inflow, and improve the

cooling effect.

Provide liquid-spray cooling and improve the

gas discharging volume.

Add economizors to some systems.

Fouling factors Evaporator Heat recovery Desuperheater

Limits to exchanger water temperature are valid within the minimum maximum water flow range indicated in the Hydraulic Data section.

(*) According to unit size

(1) Condenser air (in) 35 °C

(2) Evaporator water (in/out) 12/7 °C

(3) With low ambient temperature control (STD/OPT)

(4) Condenser air-flow rate in low-noise operating mode

(5) Condenser air-flow rate in standard operating mode

(6) With temperatures down to -8°C use anti-freeze mixtures. In case of lower temperatures, please contact our Sales Department. Always

indicate the evaporator outlet temperature when ordering

ETHYLENE GLYCOL MIXTURE

Ethylene glycol and water mixtures, used as a heat-conveying fluid, cause a variation in unit performance. For correct data, use

the factors indicated in the following table.

cPf cooling capacity correction factor

cQ flow correction factor

cdp pressure drop correction factor

For data concerning other kind of anti-freeze solutions (e.g. propylene glycol) please contact our Sales Department.

FOULING FACTORS

Performances are based on clean condition of tubes (fouling factor =1). For different fouling values, performance should be

adjusted using the correction factors shown in the following table.

f1 - f2 - f3 capacity correction factors

fk1 - fk2 - fk3 compressor power input correction factors

fx1 - fx2 - fx3 total power input correction factors
