7 Energy efficiency (according to definition EN 14511:2013) SL unit with acoustic attenuation EER value (not according to definition EN 14511:2013): The EER value (Energy Efficiency Ratio) of a chiller indicates the relationship between cooling capacity and consumed electrical power with consideration of the following measurement conditions for air-cooled units: Medium water Water inlet temperature 12 C Water outlet temperature 7 C Ambient air temperature 35 C Unit operates under full load The higher the EER value, the more energy-efficient the unit operation at 100% full load. With units that operate at full load most of the year or the whole year around, special attention should be paid to the highest possible EER value. This is often the case in production facilities or computer and data processing centers. All units are indicated including the common performance values (cooling capacity, heating capacity, electrical power consumption, EER, COP and ESEER) as well as the performance values according to EN 14511:2013.

8 Energy efficiency (according to definition EN 14511:2013) SL unit with acoustic attenuation Based on the directive EN 14511:2013, the performance values mentioned above are no longer determined as described onpage 7, but take into consideration the water-side pressure drop of the heat exchangers the external static pressing (for units with radial fans) the electrical power consumption of the pump, if the unit is supplied with an integrated pump. Consequently the usual performance values vary slightly. The basis for the determination of the performance values according to EN 14511:2013: Cooling capacity: Pc EN14511 = Pc - PΔp Heating capacity: Ph EN14511 = Ph + PΔp Electrical power consumption: Pe EN14511 = Pe + PΔp Energy efficiency cooling EER: EER EN14511 = Pc EN Pe EN14511 Energy efficiency heating COP: COP EN14511 = Ph EN Pe EN14511 Pc (EN1411) : Cooling capacity EER (EN1411): Energy efficiency Cooling: Ph (EN1411) : Heating capacity COP (EN1411): Energy efficiency heating Pe (EN1411) : Electrical power consumption PΔp Electrical power consumption of the pump in order to overcome the water side pressure drop of the heat exchanger 8 PR GB Subject to modifications R1-05/2016

9 Unit description DencoHappel GLRC - CD2 unit series DencoHappel units are chillers for indoor installation to be connected to an external condenser. The units are charged with refrigerator oil and nitrogen by the manufacturer. The chillers of series and can also be optionally supplied with a pump module for the chilled water side. The pipework of the refrigeration circuit between the unit and external condenser must be mounted, leak tested, evacuated and charged with a refrigerant on site. Besides, chilled water and electrical connections must be established and a function test must be performed. The DencoHappel unit series are designed only to be used with the environmentallyfriendly refrigerant R410A. Directives and regulations Components Units meet the following directives and standards: Directive on Machinery 2006/42/EC Low Voltage Directive 89/336/EEC & 2006/95/EC Electromagnetic Compatibility 2004/108/EC Pressure Equipment Directive 97/23/EC according to module H1 Certified Corporate Quality Management System ISO 9001 Chiller with high EER This new unit generation is characterized by high energy efficiency ratio (EER) and use of R410A refrigerant. 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 condensers have larger exchange surface areas, as do the new evaporators, which enable even better and more efficient distribution of the refrigerant in a liquid and gaseous state. The fans are controlled so as to optimise the air volume flow in each condenser section and therefore ensure that noise levels are kept to a minimum in every operational mode. The state-of-the-art system 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 when in part-load mode. A carefully dimensioned system implemented in these units produces considerable energy savings and vastly reduces operating costs. The GLAC 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. PR GB Subject to modifications R1-05/2016 9

10 Unit description Components Compressor Fig. 3: Scroll compressor Fully hermetic, low-vibration and suction-refrigerant cooled Copeland scroll compressor complete with oil heating for safe compressor start-up, electronic overheating protection with manual reset and a two-pole electric motor. These Copeland scroll compressors are also highly economical to run and have a sound power level that is some 6 db(a) lower than piston compressors. The sizes comprise 2 compressors in one refrigeration circuit. Units of model sizes are fitted with four compressors, with two compressors integrated in each of two refrigeration circuits. Evaporator Fig. 4: Plate heat exchangers 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. The unit can also be operated with glycol as standard with outlet temperatures down to -8 C. Condensers The condenser must be provided by others and connected with the unit pipework on site. Besides, the pipework of the refrigeration circuit between the unit and external condenser must be mounted, leak tested, evacuated and charged with a refrigerant.

46 Design, mounting and installation examples Instructions for planning and design Condensers Large temperature difference... Small temperature difference... Fan regulation and control single circuit or dual circuit Subcooler circuit Set the condensing temperature for the chiller. Consider the operating limits of the unit. Refer to page 38 for the corresponding operating limits. The larger difference between condensing temperature and ambient temperature in the layout stage, the smaller condenser can be selected. Disadvantages of a smallerdimensioned condenser are increased noise levels as a result of high air velocity and/ or increased energy consumption because of higher condensing temperature together with reduced cooling capacity. The smaller difference between condensing temperature and ambient temperature in the layout stage, the larger condenser should be dimensioned. Through a large-dimensioned condenser the condensing temperature can be maintained low, which enhances capacity and energy efficiency. The disadvantage is about larger refrigerant charge volume for the designed condenser and increased installation space requirements. Depending on the region, practical values for temperature difference between condensing temperature and ambient temperature in the layout stage amount to 10 to 15 K, i.e. condensing temperature exceeds the layout parameters of ambient temperature by 10 to 15 C. Under all circumstances the condenser must be selected at least with the corresponding fan regulation or optimally with a fan speed control in order to ensure constant condensing pressure throughout the year. Significant fluctuations in condensing pressure should be avoided. In any case, the minimum condensing pressure after compressor start must be ensured. Maximum allowed condensing temperature must not be exceeded. For the chiller a single-circuit condenser must be selected. Chillers of series require a dual-circuit condenser. Using a single-circuit condenser for units with two refrigeration circuits is not allowed because of different oil distribution. Select a condenser with an integrated subcooler circuit. Minimum subcooling must amount to at least 3 K, because only under these conditions the expansion valve receives a bubble-free liquid in case of 10 m rising liquid line. If the subcooling is smaller or the height difference is greater, the expansion valve can be damaged and the unit must operate with a reduced output anyway. Refer to the documentation provided by the manufacturer for further details on layout and installation of air cooled condensers. Refrigerant lines Only copper refrigerant lines meeting DIN EN standards may be used. The relevant requirements especially apply to: Quality of internal surfaces Sealed pipe ends Pipe labelling Testing Pressure resistance 46 PR GB Subject to modifications R1-05/2016

47 Design, mounting and installation examples Instructions for planning and design Line lengths and dimensions Short line lengths Oil transportation must be ensured Keep pressure drop as low as possible Oil traps Refrigerant receiver Keep the pipe length as short as possible. The greater the distance between chiller and field-provided condenser, the greater are the pressure drops in connected pipes, resulting in worse energy efficiency of the unit. Refer to the following "Placement and installation examples" on page 47 for the maximum distance and height difference between chiller and field-provided condenser. When dimensioning the pipes, make sure that oil transportation is ensured under all operating conditions. Oil transportation must be ensured using the corresponding pipe dimensioning and pipe routing. It is also important that the pressure drop in the pipework is minimized to avoid unnecessary decreases in capacity. The greater the selected pipe diameter, the lower is the speed in the pipe, and the more difficult is the oil return. The smaller the selected pipe diameter, the higher the speed and the greater the pressure drop in the pipe. The units loses capacity and energy efficiency. 1 % slope Always provide a 1 % slope (1 cm/m) for the discharge line in the direction of flow. Install oil top and bottom trap, as described in page 47 and following pages. Dimensioning of refrigerant lines on page 49 is valid for water inlet and outlet temperature of 12/7 C and condensing temperature of 47 C. For other temperatures individual pipework calculation must be performed. With long and winding pipe runs and often low load reduction combined with short compressor running times it is reasonable to install an oil separator in the field-provided discharge line. Consider the manufacturer's instructions regarding the layout of an oil separator and the relevant manual for the installation. Installing a refrigerant receiver is not mandatory. With long pipe runs and year-round operation of the unit it is, however, recommended to install a refrigerant receiver. In case of a year-round operation, ensure that a minimum condensing temperature is maintained. If necessary, winter start regulation must be installed to maintain a minimum condensing temperature. If a receiver is not installed, the refrigerant must be selected and charged with due care. When charging the unit with refrigerant at low ambient temperature, ensure that the system is not overfilled and the unit can be trouble-free operated at high ambient temperature as well. Consider the manufacturer's instructions on layout of a refrigerant receiver and installation manual for mounting a receiver.

68 Pump module Unit design and description of GLPE with pump module DencoHappel chiller with GLPE with a pump module and unit series can be supplied with an optional pump module. This significantly reduces the on-site installation costs. Main components of a pump module: One or two water pumps Fill and drain valve Air-vent valve Safety valve (6 bar) All above-mentioned components are already fitted and wired in the unit. On site only the water pipework has to be connected to the hydraulic network; furthermore, the electrical supply line must be connected to the master switch of the unit. The actuation and power supply of the water pump with the corresponding water inlet and outlet times is performed by the unit control.

69 Pump module Unit design and description of GLPE with pump module Other optional accessories Second pump The pump module can be equipped with a second pump for redundant change-over operation. The chiller control system regulates the pump activations in order to compensate operating hours or if a pump failure occurs. Pump modules with two pumps are equipped with a non-return valve for each pump. Note! Dimensions and weight of the unit change, depending on the selected unit type. Please refer to order-related documentation for exact sizes. Note! Under all circumstances remember to install an additional flow switch at chilled water outlet of the unit and connect it to terminals A-B in the switch box of the unit. The additional flow switch can be optionally ordered and is a requirement for safe and trouble-free operation of the unit and thus constitutes an integral requirement to uphold the validity of the warranty.
