530 Efficient heating down to -25°C High heating capacity at low ambient temperatures J Stable heating capacity available down to -15°C WB! High partial load efficiency J New vapour injection scroll compressor optimised for low load - UNIQUE back-pressure control: Pressure port increases pressure below the scroll in low load operation, preventing refrigerant leak and increasing efficiency - UNIQUE Injection structure with check valve: Prevents volume backflow during low load operation typically occuring with standard vapour injection compressors J Variable Refrigerant Temperature adjusts refrigerant temperature to match the load High reliability down to -25°C WB J Hot gas bypass prevents ice buildup at the bottom of the heat exchanger RXYLQ-T Pressure port Lower pressure High pressure pressure Ambient temperature [°CWB] VRV3-C VRV4-C Heating capacity [kW] 0 -15 -25 -20 5 -10 10 -5 20 25 30 35 40 45 50 Cold climate series
