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%, and 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 6.7 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 Effi ciency and Certifi cation 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 6.7 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 effi ciency 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 fi gures 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 refl ects 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 effi ciency 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 effi cient refrigerant distribution both in the liquid and steam phases. The fans with elevated unit effi ciency are suitably adjusted to optimise air fl ow 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 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 (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 signifi cant 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. 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 effi ciency 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 fi ne 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 fi tted with manual-reset motor thermal protection, delivery gas temperature control, an oil level fl oat, an oil level sight-glass and an electric resistance for heating the oil when the compressor is stopped. Water-refrigerant heat exchanger AISI 316 steel braze-welded plate exchanger. The heat exchangers are insulated with a closed-cell condensation proof lining in neoprene. A thermostatically controlled electric heater prevents ice from forming inside the evaporator when the unit is not working. When the unit is working, it is protected by a differential pressure switch mounted on the water side. The unit can work with antifreeze mixtures at exchanger outlet temperatures as low as -8 C. Water side filter Y type fi lter designed and built to retain impurities in the hydraulic circuit. It features a stainless steel mesh cartridge with 0.9mm holes which can be replaced easily without removing the valve from the piping. Refrigerant-air heat exchanger Aluminium fi ns and copper tubes type heat exchanger. The aluminium fi ns are correctly spaced to guarantee the best heat exchange effi ciency. 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 profi led die-cast aluminium blades. Housed in aerodynamic hoods complete with safety grille. 6-pole electric motor with built-in thermal protection. 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 fi ve and six-lobe rotors. The fi ve-lobe rotor is directly splined onto the 2-pole motor (2,950 rpm) without the use of overgears. Compression occurs fi ve 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 fi tted with electric starting devices which limit the 1 HFC R134a

25 6. HYDRONIC GROUP This units can be supplied with water pumping group complete, if required, with refrigerated water tank. Concerning the pumping group, it s possible to order: 1 pump, 2 poles, low head pressure 1 pump, 2 poles, high head pressure 1 pump, 4 poles, low head pressure 2 pumps, 2 poles, low head pressure 2 pumps, 2 poles, high head pressure 2 pumps, 4 poles, low head pressure The system capacity can be increased by installing an accumulator between the refrigeration unit and a user. Thanks to the increased thermal inertia, this ensures a number of advantages: - Longer life of the refrigeration machines due to longer working time of the compressor between two starts. - Reduced water temperature swings, which results in greater stability of final adjustment. The pumping group and, when required, the water tank are directly installed inside the main unit, on the base frame HIDRONIC UNIT OPTIONS 2-pole low head pump All versions of the hydronic unit can be supplied with a low head 2-pole pump. This pump is recommended for all version B units. 4-pole low head pump All versions of the hydronic unit can be supplied with a low head 4-pole pump. This pump is recommended for all version LN or SL units where low noise levels for the entire chiller are required. 2-pole high head pump All versions of the hydronic unit can be supplied with a high head pump. In these cases, the pump is always fitted with a two-pole motor. Second pump A second stand-by 2- or 4-pole pump for high or low pressures is available on request. The pumps are automatically exchanged on the basis of a rotation programme and the stand-by pump cuts in automatically if the primary pump fails. The two-pump hydronic unit is also fitted with check valves to ensure it works correctly. Special pumps Contact our sales office if you require pumps with different configurations. Storage tanks The internal storage tank, made from hi-tech welded steel sheet and painted to prevent corrosion, can be combined with all the above pumps. Each tank is tested to 7.5 bar to ensure an operating pressure of 5 bar. The condensation-proof lagging is made from a 20 mm layer of foamed cross-linked polyethylene bonded to an external embossed metallic scratchproof film. 21 HFC R134a
