4 Overview Energy Indicies IPLV and ESSER In Europe increasing attention is paid to the energy consumption of air conditioning equipment. It is not only the efficiency of air-conditioning equipment under nominal conditions that has been used as a basis in the U.S. for many years. An assessment index is also used, which considers operation of the unit under partial load conditions as well as nominal conditions. In part load operating mode ambient temperature is remains below the nominal value and the refrigerant compressors operate at part load speed. The assessment index used in the USA is known as IPLV (Integrated Part Load Value) and is defined in a guideline issued by the ARI (American Refrigeration Institute). ARI Norm: IPLV ARI = (1 EER 100% + 42 EER 75% + 45 EER 50% + 12 EER 25% ) / 100 EER100%, EER75%, EER50%, EER25% stand for the chiller efficiency under a number of different part load conditions (100 % - 75 % - 50 % - 25 %), calculated given the ambient temperature conditions listed below. The temperature of the chilled water at the evaporator outlet is assumed to be a constant 6,7 C under part load conditions, with ΔT of 5 K at full load. The multipliers 1 %, 42 %, 45 % und 12 % are the respective percentage weightings of the efficiency levels for the different part load conditions as specified by the ARI Standard. These were determined by ARI, based on investigations of various building shapes in 29 American cities. Water at the evaporator outlet: 6,7 C ΔT at full load: 5 C Load: 100 % 75 % 50 % 25 % Outdoor air temperature: 35 C 26.7 C 18,3 C 12.8 C Taking into consideration normal European conditions it is difficult to imagine that a chiller would operate at outdoor air temperatures below 20 C. Besides, legal codes and regulations (including drafts) tend to enforce obligations on producers with an aim to reduce energy consumption and promote the application of systems that can directly or indirectly make use of outdoor air if ambient conditions allow this. In Europe the EECCAC (Energy Efficiency and Certification of Central Air Conditioner) study was carried out to adapt the US-related IPLV (Integrated Part Load Value) to European climate conditions. The ESEER (European Seasonal Energy Efficiency Ratio) was developed within the framework of this guideline. EECCAC suggestion: ESEER = (3 EER 100% + 33 EER 75% + 41 EER 50% + 23 EER 25% ) / 100 Water at the evaporator outlet: 6,7 C ΔT at full load: 5 C Load: 100 % 75 % 50 % 25 % Outdoor air temperature: 35 C 30 C 25 C 20 C ESEER IPLV weighting/part load speed [%] Weighting Part load weighting/part load speed [%] Weighting Part load Outdoor air temperature C / ESSER Outdoor air temperature C / IPLV 4 PR GB Subject to modifications Status 12/2009

Unit Type IPLV ESEER Tab. 1: Basic unit (energy indices) Unit Type IPLV ESEER Tab. 2: SL unit (energy indices) The actual energy can be calculated more precisely in a dynamic form by considering the load progression curve in relation to changes of outdoor temperatures, the installation location and the relevant number of operating hours. With this data every system operator or system designer can bring their own considerations into play depending on the type of a building, location, the type of heat load and other factors. The energy index can also be determined by using the method that best corresponds to the system requirements, compares energy aspects of similar or equal systems and uses the same reference unit.

6 Unit Description GEA GLAC BD2 Unit Series These GEA units are air cooled chillers with axial fans designed for outdoor installation. In the factory they are filled with refrigerator oil and refrigerant and a test run is performed, so that when the units are installed on site only chilled water and electrical connections have to be established. Client witness test must also be carried out. The GEA unit series are designed only to be used with the environmentally-friendly refrigerant R410A. Components Chiller with high EER This new unit generation has a high energy efficiency ratio (EER) and uses the refrigerant R410A. An optimum result was achieved by carefully designing all internal components so as to fully exploit the performance characteristics of the specific refrigerant. Particular attention was paid to the surfaces of the heat exchangers, as well as the fans and compressors. The newly designed evaporators have larger exchange surface areas and enable even better and more efficient distribution of refrigerant in a liquid and gaseous state. The advantage of the GLRC unit series with an external condenser is the indoor installation of the chiller without the necessity to use glycol as antifreeze agent. Besides, the chiller can be installed by utilizing needed space to a maximum in locations where unit operation does not lead to inconvenience caused by noise. For especially noise-sensitive locations the unit condenser can be designed to meet the relevant requirements. Moreover, units without a condenser usually have a higher energy efficiency as compared to water-cooled units, because operation of such units does not involve an auxiliary heat exchanger and a cool water pump. State-of-the-art system of the newest generation The intelligent control of the chilled water outlet temperature reduces fluctuations in relation to the specified setpoint and vastly reduces the time the system needs until it is ready for operation. The precision and rapid reaction of the intelligent control system facilitate optimum control in the event of load fluctuations which means that stable operating conditions can be achieved very quickly, even during part load operation. A carefully dimensioned system implemented in these units produces considerable energy savings and vastly reduces operating costs. The GLRC unit series are water cooling systems that are particularly suitable for small and medium-sized air conditioning systems or for systems designed for low water system content. The main difference when compared to conventional units is the intelligent controller system. Basic construction The frame and panels are made of galvanized, plastic-coated sheet steel (RAL 9002). The self-supporting construction offers excellent access to the individual components during maintenance and repair work. Compressor Fully hermetic, low-vibration and suction-refrigerant cooled scroll compressor complete with oil heating for safe compressor start-up, electronic overheating protection with manual reset and a two-pole electric motor. These scroll compressors are also highly economical to run and have a sound power level that is some 6 db(a) lower than piston compressors. 6 PR GB Subject to modifications Status 12/2009

7 Unit Description GEA GLAC BD2 Unit Series Fig. 1: Plate heat exchanger Evaporator The evaporators used in this unit series are plate heat exchangers made of AISI 316. The advantages of plate heat exchangers are their very compact construction combined with high performance. The channel plates consist of stamped stainless steel plates that are closely connected using a special soldering technique. This means that a high-turbulence flow occurs on both primary and secondary sides which results in an extremely efficient exchange of heat between the refrigerant and the heat transfer medium. This construction also means that the required amount of refrigerant can be reduced to a minimum. The evaporator is non-permeable and is provided with comprehensive abrasion-resistant insulation. When in operation the evaporator is protected against insufficient flow by a standard provided flow switch. As standard, if glycol is used, the unit can operate at outlet temperatures of up to -8 C. Evaporator heating Evaporator heating is controlled via the microprocessor depending on the water outlet temperature to prevent the evaporator from freezing in standby mode. Water filter Before the direct inlet of the evaporator a water filter that protects the heat exchanger from dirt and scale must be installed. The water filter of Y-type has a mesh width of 0,9 mm. The filter body can be trouble-free removed and cleaned for maintenance purposes without dismantling the valve body. Fig. 2: Water filter Condenser Finned tube heat exchanger have copper fins and corrugated aluminium fins. The best possible heat exchanger efficiency is achieved through even spacing of the fins. Two condenser sections of both circuits are separated by galvanized sheet steel, which ensures their complete autonomy. Fans Direct driven axial fans (protection type IP54) provided with deep drawn rotor made of sheet steel and 6-pole motor with overheating protection and maintenance-free ball bearings. Assembled in a streamlined form and fitted with a protective grille. In order to ensure efficiency factor at part load, the fan groups per each refrigeration circuit are separated on the air side. Refrigeration circuit Each refrigeration circuit contains the following components: Filter drier Sight glass with humidity indicator Thermostatic expansion valve with external pressure equalisation Shut off valve in liquid line (starting from unit size 0904) Electronic pressure sensor on discharge side Safety valve on pressure and suction side High and low pressure manometer High and low pressure switch Service valves on suction and pressure side, liquid and injection line.
