3 1. ENERGY INDICES 1.1 Energy indices ESEER and IPLV Increasingly closer attention is being paid towards the power consumption of air-conditioning equipment, both in Europe and elsewhere. For many years in the United States, reference has not just been made to effi ciency at rated conditions. A valuation index is also used which considers marginal operation of the unit at rated conditions as well as increased 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 defi ned in the regulations issued by ARI (American Refrigeration Institute). ARI Standard (1) IPLV ARI = (1*EER 100% + 42*EER 75% + 45*EER 50% + 12*EER 25% ) /100 where EER100%, EER75%, EER50%, EER25% are the effi ciencies of the chiller in the various load conditions (100% - 75% - 50% and 25% respectively), calculated in the operating conditions shown below. The temperature of the water leaving the evaporator is considered constant at.7 C in all load conditions, with a delta of 5 C in the full load condition. The multipliers 1, 42, 45 e 12 are the cooling performance coeffi cients in various load conditions statistically calculated by ARI an the basis of surveys conducted, for various types of buildings and operating conditions, in 29 American cities.

Airconditioning 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). 125 (%) 100 ESEER IPLV Load- Weight Coeffi cient Load Weight Coeffi cient Load Weight Coeffi cient External air temperature ( C) External air temperature ( C) Load Air Temp.

4 In Europe there is a proposal for EECCAC (Energy Efficiency and Certification of Central Air Conditioner) Proposal EECCAC (2) ESEER = (3*EER 100% + 33*EER 75% + 41*EER 50% + 23*EER 25% ) /100 where Evaporator temp. leaving 7 C constant DeltaT full load 5 C Load 100% 75% 50% 25% Cond. inlet water temp. 35 C 30 C 25 C 20 C Using the energy indices 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.

5 2. UNIT DESCRIPTION 2.1 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. Simultaneous adjustment of the unit, based on the control of the temperature of the water leaving the evaporator, assures an extremely restricted variation with respect to the setpoint. 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. 2.2 Standard unit composition Supporting frame Frame with base in polyester-painted thick hot-galvanised sheet steel. Shaped aluminium walls. Panelling The external panelling, made from aluminium alloy for total corrosion resistance, offers maximum ease of access to the internal components. 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 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 anti-condensation lining. The copper pipes are internally grooved so as to improve the heat exchange. The pipes are mechanically expanded onto the tube 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 die-cast aluminium blades. Housed in aerodynamic hoods complete with safety grille. -pole electric motor with built-in thermal protection. 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 1 _1542_242_200909_GB HFC R134a
