Abstract (en)

[origin: EP0916914A2] A refrigerating cycle with a by-pass duct 5 in which heat exchange for heating is arranged to be performed in an evaporator 4 without passing refrigerant through a condenser 2 is designed to perform an auxiliary heating mode suitable for the instantaneous conditions by controlling the amount of refrigerant circulating in response to the load and the like. Said by-pass duct 5 for supplying the refrigerant from the compressor 1 to the evaporator 4 without passing it through the condenser 2 is placed in juxtaposition. Between the outlet of the evaporator 4 and the inlet of the compressor 1 an accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided so that the amount of refrigerant circulating is controlled by accumulator 6 while the refrigerant circulates via by-pass duct 5 without passage through condenser 2. <IMAGE>
