    摘要： Heating equipment, including a first heat exchanger, a compressor, a second heat exchanger, and a first expansion valve that decompresses a refrigerant flowing from the second heat exchanger to the first heat exchanger, are connected so as to circulate the refrigerant. A third heat exchanger provides heat of the refrigerant flowing from the second heat exchanger to the first heat exchanger to the refrigerant flowing from the first heat exchanger toward the compressor. An injection circuit merges part of the refrigerant flowing from the second heat exchanger to the first heat exchanger with the refrigerant that is sucked by the compressor. An injection expansion valve is installed in the injection circuit and decompresses the refrigerant flowing in the injection circuit. A fourth heat exchanger is installed in the injection circuit to supply heat of the refrigerant flowing from the second heat exchanger toward the first heat exchanger to the refrigerant flowing in the injection circuit.

    摘要： A highly reliable refrigeration cycle having a residual refrigerant, which is designed that the refrigerating machine oil does not stagnate in the refrigeration cycle after flowing out from the compressor even if the refrigerating machine oil is weakly soluble in a refrigerant. Thus, the compressor may be prevented from the exhaustion of oil. In addition to that, even if the accumulator is removed from the cycle, a large amount of wet vapor suction into the compressor may also be avoided. A control section is provided for controlling saturated oil solubility in a liquid refrigerant in the refrigeration cycle. The control section includes a receiver and first and second flow regulators which are placed before and after, respectively, the receiver. A residual liquid refrigerant obtaining in the circulation of a refrigerant is reserved in the receiver at a high temperature so that the weakly soluble refrigerating machine oil is prevented from separating.
