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%

) /100ARI 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 leaving the 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.

Proposal EECCAC ESEER = (3*EER100%

+ 33*EER75%

+ 41*EER50%

+ 23*EER25%

) /100

In Europe there is a proposal for EECCAC (Energy Efficiency and Certification of Central Air Conditioner)

Using the energy indices

Temperature changes on the condenser water inlet are a characteristic of use of cooling towers, an installation solution

widely used in big air conditioning systems. In any case the components must be designed against the maximum outdoor

temperature.

After establishing which index to use and estimating the total power 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

The real power calculation can be obtained more correctly in a “dynamic” form, that is, considering the load performance

curve at different external temperatures, the location and the reference number of operating hours.

These figures will allow plant consultants and designers to make their evaluations depending on the type of building, the

place of installation and the type of heat load. etc.. They can also determine the energy index using the method that best

reflects plant requirements and can 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,

compressors and new asymmetrical evaporators with improved and more efficient refrigerant distribution both in the liquid

and steam phases.

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 with Quick Mind adjustment logic, guarantees extremely small variations

compared with the set point (+/- 0.5 °C, probe precision limit) as well as considerably reducing the time required for the

system to become fully operative.

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

valves.

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.

Water-to-water chillers

Water-to-water chillers. 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 COMPOSITIONSupporting frame

Frame comprising supporting elements in polyester-painted thick hot-galvanised sheet steel. The self-supporting frame

containing the main components is designed to ensure maximum ease of access during servicing and maintenance operations.

The various components have been arranged to reduce the overall dimensions of the unit to a minimum.

Screw compressors

Semi-hermetic screw-compressors with 2 five and six-lobe rotors. The five-lobe 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 modulatedfrom 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.

Direct expansion shell and tube exchanger with asymmetric refrigerant circuits for keeping the refrigerant at the correct

speed inside the tubes during the change from the liquid to the gaseous phase. The steel shell is insulated with a closed-cell

condensation proof lining in foamed elastomer. The copper pipes are internally grooved to improve heat exchange and are

mechanically expanded onto the tube plate ends.

Refrigerant-water heat exchanger

Finned coil exchanger with steel shell and finned coil made from copper tubes with external fins, mechanically expanded

onto the tube plate ends. The heads can be removed to inspect the tubes. Water connections are fitted standard for water

from towers; connectors for water from wells can be supplied on request.

Basic model

Unit without heat recovery.

Model with partial heat recovery (D)

Water 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.

Model with total heat recovery (R)

Water cooled chiller with total heat recovery. This version features an oversized water/freon heat exchanger with a dual

water circuit comprising a dual shell and tube exchanger for heat condensation and total recovery, all enclosed in a single

steel shell with removable heads and externally lagged in closed-cell neoprene. This exchanger is large enough to recover

condensation heat and produce hot water (secondary or recovery circuit). Hot water can be produced in the recovery circuit

for domestic hot water and the like. The heating capacity of this circuit is approximately equal to the cooling power plus the

power input of the compressor.

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.

(1) Condenser water temp. 30/35 °C

(2) Evaporator water (in/out) 12/7 °C

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

(4) Values related only to total heat-recovery version.

(5) Valid for temperature of fluid the evaporator >= -3°C. In case of lower temperatures, please contact our Sales Department.

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

SIZE

WATER FLOW AND PRESSURE DROP

Water flow in the heat exchangers is given by:

Q=Px 0,86/Dt

Q: water flow (m3/h)

Dt: difference between inlet and outlet water temp. (°

C)P: heat exchanger capacity (kW)

Pressure drop is given by:

Dp=K x Q2 /1000

Q: water flow (m3/h)

Dp: pressure drop (kPa)K: unit size ratio

Q min: minimum water flow admitted to the heat exchanger.

Q max: maximum water flow admitted to the heat exchanger.

W.c min.: minimum water content admitted in the plant.

(1) Rec. = Heat Recovery. For units with total heat recovery.

(2) Cond. = Condenser. For water to water type units. In units with heatrecovery ,

this data is valid for both the condensing and the heatrecovery exchangers.
