Abstract

PURPOSE: To make the capacity of a refrigerating cycle variable by providing a heat pump cycle, a gas injection circuit and a gas bypass circuit.
CONSTITUTION: A compressor 1, a four-way valve 2, an indoor heat exchanger 3 and an outdoor heat exchanger 4 connected in a loop form a refrigerating cycle of a heat pump type, and between the heat exchangers 3 and 4, a gas and liquid separator 5 is installed. On the gas side of the gas and liquid separator, a gas injection circuit A which returns unrequired gas to the injection port 1a of the compressor 1 is installed and a two-way valve 6 and a check valve 7 are provided on the way. From the pipe connecting the four-way valve 2 and the indoor heat exchanger 3, a circuit C is branched, and a check valve 8 which can be opened only to the branch point is interposed and its other end is connected to the delivery side of the check valve 7. By so constructing, the capacity of the refrigerating cycle can be made variable.
