Abstract: A refrigerating cycle apparatus includes an evaporator, a compressor, a condenser, a feeding channel, a main circuit that circulates a refrigerant including fluid whose saturated vapor pressure at ordinary temperature is a negative pressure as a main component, a heat absorption circuit including a heat absorption heat exchanger, a heat release circuit including a heat release heat exchanger, an internal heat exchanger that allows indirect heat exchange between the fluid flowing through the heat absorption circuit and the fluid flowing through the heat release circuit, at least one of a heat absorption bypass channel and a heat release bypass channel, and at least one of a flow rate adjustment mechanism for heat absorption that adjusts a flow rate of the fluid flowing through the heat absorption bypass channel and a flow rate adjustment mechanism for heat release that adjusts a flow rate of the fluid flowing through the heat release bypass channel.

Abstract: A refrigeration cycle apparatus includes an evaporator, a first compressor, an intercooler, a second compressor, a condenser, and a refrigerant liquid supply passage. The intercooler stores refrigerant liquid and also cools refrigerant vapor compressed by the first compressor and expels it. The second compressor sucks in the refrigerant vapor expelled from the intercooler and compresses it. The intercooler includes a container, an intercooling passage, and a pump. The container contains a vapor space and stores refrigerant liquid. The intercooling passage is a passage in which a part of the refrigerant liquid stored in the container flows and that supplies the part of the refrigerant liquid to the vapor space. The pump pumps a part of the refrigerant liquid stored in the container to the vapor space.
