144 144 Refrigeration - FAQ FAQ

145 FAQ - Refrigeration Rule of thumb: What is the EER value and how is it calculated? The EER (energy efficiency ratio) defines the performance number of a refrigeration unit, i.e. the ratio of the cooling produced to the consumption of electric energy. EER = Q 0 /P KL 145 How is the ratio of cooling capacity to the clamp achievement (EER) of the acr rental machines? Dependent on air or water-cooled chillers, the efficiency varies considerably. Our large cooling systems with centrifugal-compressors for example reach EER values of > 5. For the standard product assortment, the following values can be assumed. - EER in deep cooling machines 1 to 2 - EER in air cooled chillers 2.5 to EER in water cooled chillers 3.5 to 6 Is there a guideline for the variation of the cooling capacity per C temperature change of the cold water temperatures? As a rule of thumb, per K temperature reduction the cooling capacity decreases by about 4%. Is there a guideline for the flow rate in dependence of the cooling capacity? As a guideline, for the flow rate per kw cooling capacity, dependent on t (temperature difference between cold water inlet and discharge) the following values can be assumed. t 4K 215 l/h per kw cooling capacity t 5K 172 l/h per kw cooling capacity t 6K 143 l/h per kw cooling capacity t 7K 123 l/h per kw cooling capacity t 8K 108 l/h per kw cooling capacity t 9K 96 l/h per kw cooling capacity t 10K 86 l/h per kw cooling capacity > In practice the cold water temperature difference is between 5 and 8K Which tube sizes and couplings are used for which cooling capacities? On the basis of acr experience, the following tubes and couplings can be used in the various different cooling capacity ranges, up to the maximum length of 100 meters. Cooling capacity Tube size Coupling < 20 kw DN 40 Storz C kw DN 50 Storz C kw DN 80 Storz B kw DN 100 Storz A > 800 kw DN 125 Storz 125 FAQ

146 FAQ - Refrigeration How is the cooling capacity affected by the soiling factor (Fouling Factor)? 146 Soiling factor [m² C / kw] Correction factor of the cooling capacity Correction factor of the power consumption Correction factor of the performance number (EER) For which operational areas are the air cooled chillers suited? The chillers are suitable for the unrestricted operation at 35 C outside temperature and operate in the capacity restricted mode in ambient temperatures up to 50 C. For use in lower ambient temperatures, the cold water chillers equipped with variable speed ventilators and vaporizer heating are suitable. In this way operation is possible at lower temperatures. At extremely low ambient temperatures and particular locations as well as when light cooling loads prevail, additional measures must be taken. Application area of air cooled chillers The sound values of the acr rental machines are specified at a distance of 5m. How much does the sound value decrease when the distance is doubled to 10m? Generally the sound pressure level is specified according to ISO 3744 in a hemispherical field at 1m distance. As a rule of thumb, the sound pressure is reduced by about 4 db(a) when the distance is doubled. For example a sound pressure level specification of 66dB(A) at 5m distance equates to a sound pressure level of about 62dB(A) at 10 meters, and at 20m about 58dB(A) and so on. FAQ

The refrigerant has a direct heat transition to the air and therefore the liquefaction of the refrigerant is directly passed through to the environment.

147 FAQ - Refrigeration Machine basics: Wherein do air cooled and water cooled chillers differ? Air cooled chillers (fluid cooler) distinguish themselves through their compact design and are available in a capacity range of 5 2,000kW. The refrigerant has a direct heat transition to the air and therefore the liquefaction of the refrigerant is directly passed through to the environment. Water cooled chillers are more efficient, however through an external drycooler unit they are also substantially more expensive and costlier to install. In the rental segment, the cooling capacity range is between 5 and 4,500kW per unit. 147 What is the difference between Scroll- and screw compressors? Because the compressor is an especially important part of a refrigeration unit, this question will be answered especially in detail. According to requirements and capacity range, scroll-, screw or centrifugal compressors are implemented. Scroll compressors are implemented in a capacity range of 5 100kW cooling capacity and are fully hermetically sealed. Several compressors can be used together in a refrigeration circuit. In this way capacity ranges of up to 600kW and more can be reached by the so-called Multiscroll units. The compression of the refrigerant is achieved by the orbital path of a moving spiral in a fixed spiral at about 2900 RPM at 50Hz. Fully hermetically sealed scroll compreessor (Danfoss) The current power adjustment herewith takes place by activating and deactivating individual compressors. In following example, four compressors provide for 100% cooling capacity. In the case of 85% loading, three compressors are continuously in operation and the fourth is engaged or disengaged as needed. To protect the compressor, the frequency of engaging / disengaging should not exceed six times per hour. > cold water temperature variations through engaging and disengaging of the compressor Compression principles in Scroll compressors (Bitzer) Betriebszyklus Scrollverdichter Semi-hermetic screw compressors are available in a capacity range of 100 1,200kW cooling capacity. With up to three separate refrigeration circuits, cooling capacities of over 2.000kW per unit can be achieved. The compression of the refrigerant is achieved by a continuous and on vibrating rotation of the screw at about 2,900 RPM at 50Hz. In the following photo, a McQuay single rotor screw compressor is shown. The single rotor screw compressor consists of a main rotor directly connected to the motor and two diametrically opposite, interrelated and geared addition rotors. The simultaneous flow of intake and compression leads to an almost complete cancellation of radial and axial forces and therefore to very slight bearing loads. FAQ

152 152 Heating - FAQ FAQ

153 FAQ - Heating Grundlagen: What is the COP value and how high is the average value for the air-water heat pumps? The EER (energy efficiency ratio) defines the performance number of a heat pump, i.e. the ratio of the heating produced to the consumption of electric energy. The acr heat pumps have an average COP value between 3.5 and How is the heating requirement of a room, hall or tent determined? In dependence of the room height, the geographic alignment, the insulation, the window areas as well as the number of people and computers, the necessary heating capacity needs to be observed individually. As a criterion, following experience values can however be assumed Offices W/m 3 Hall W/m 3 Tents W/m 3 Which advantages does an air-air heat pump offer compared a conventional directly fuelled heating system? The air-air heat pumps utilize the heat pump principle and the heating costs amount to about 50% of conventional heating. Only electric current is used to drive the pump and therefore no fuel supply is necessary. The acr heat pumps can have the circulation be switched to allow for heating as well as cooling with a single device. Under which conditions can air-air heat pumps be implemented without hesitation? Air-air-heat pumps withdraw energy from the outside air using the functional principle of a heat pump to transfer the comfortable warmth to the inner rooms of an office, tent or warehouse. This technology can be utilized at temperatures down to + 5 C without efficiency losses. Under colder conditions, the conventional acr heating systems are better suited. How different are air-air to air-water heat pumps? Air-air-heat pumps and air-water-heat pumps both use air as a heat source. In the air-air-heat pumps, the warmth carrier medium is air and a capacity of 30 to 120kW and at temperatures of + 15 to + 30 C can be covered. In the air-water-heat pump, the warmth carrier medium is water and a capacity of 10 to 500kW per unit and at temperatures of + 30 to + 50 C can be covered. If temperatures over 50 C are required, conventional heating systems should be used. FAQ

The pressure loss in the tube depends on various factors. Dependent on the fittings, the medium and the bend of the tubes the pressure loss can vary up to 50%. The pressure loss is in a 2nd power relationship to the current volume, i.e. at double current volume the pressure loss is fourfold. At a specified actual current volume and the tube diameter used, a more exact value can be calculated. The pressure loss chart serves as a guideline for the medium water in a tube length of 10m at room temperature. At temperatures below 4 C, the addition of an antifreeze is required. It has to be taken into consideration that this leads to an increased pressure loss. For longer tube connections, the values can be added up proportionally. Hose bends can account for a pressure drop of up to 50%. For fittings, a 5% pressure loss per fitting can be assumed as a rule of thumb.
