Technical data LA 6TUR+ Cooling compressor 2 W9 W A27 54,5 kw / 2,8 72,7 kw / 3,4 A 48,5 kw / 2,3 65,8 kw / 2,8 Note: 1) This data indicates the size and capacity of the system according to EN 111. For an analysis of the economic and energy efficiency of the system, the bivalence point and regulation should be taken into consideration. These specifications can only be achieved with clean heat exchangers. Information on maintenance, commissioning and operation can be found in the respective sections of the installation and operating instructions. The specified values have the following meaning, e.g. A7 / W: Heat source temperature 7 C and heating water flow temperature C. 2) The specified sound pressure level corresponds to the operating noise of the heat pump in heating operation with a flow temperature of C. The specified sound pressure level represents the free sound area level. The measured value can deviate by up to 16 db(a), depending on the installation location. 3) Please note that additional space is required for pipe connections, operation and maintenance. 4) The heat circulating pump and the heat pump manager must always be ready for operation. 7) Depending on the heat pump type and refrigerant used, the maximum flow temperatures in heating operation may be reduced when the outside temperature falls. Further information can be found in the operating limit diagram for the heat pump. If the supporting feet are used, the level can increase by up to 3 db (A). 8) Domestic hot water preparation via additional heat exchanger operating in parallel: The waste heat output and/or the attainable cylinder temperature is dependent on the respective operating point (temperature level/performance level). The waste heat output falls as the cylinder temperature rises. 9) The specified coefficients of performance are also achieved in parallel domestic hot water preparation via additional heat exchangers. 1) The values specified apply when using the hydraulic 4-way reversing valve, available as an option (observe instructions for accessories). The heat outputs are reduced by approximately 1%, and the COPs by approximately 12%, when the 4-way reversing valve is not used. 11) Considerably higher COPs are achieved with cooling operation and waste heat recovery using additional heat exchangers. 12) This results in a cooling water temperature difference of 5K +/-1K for the A/W, B2/W or W2/W in 2 compressor operating mode. This is necessary for ensuring waste heat recovery in cooling operation. 2/7 Print date: 1.5.2 Telephone: +49 (9221) 79 21 Fax: +49 (9221) 79 924 339
