摘要:
An on-off valve (70) is provided in an oil feed path (43). When liquid refrigerant enters the oil feed pipe (43) from the oil separator (22), the temperature of the liquid refrigerant whose pressure has been reduced in the on-off valve (70) dramatically decreases. When the amount of such a decrease in temperature detected by a temperature sensor (73) exceeds a specified amount, it is determined that the liquid refrigerant enters the oil feed pipe (43), and the on-off valve (70) is closed.
摘要:
An air conditioner includes an indoor heat exchanger (radiator) and a controller. The radiator causes heat radiation to be performed with respect to air from a supercritical refrigerant during heating operation. The controller controls a room temperature by causing a high-pressure side pressure and a refrigerant outlet temperature of the radiator to reach respective target values. Preferably, the controller detects a refrigerant outlet temperature of the radiator with an outlet temperature sensor and detects a room temperature with a room temperature sensor. The controller increases or decreases a target value of the high-pressure side pressure when the controller has judged that there is an excess or a deficiency of capacity in view of the room temperature inside a room that is to be heated even when the refrigerant outlet temperature of the radiator has reached a target value during heating.

摘要:
In a compression/expansion unit (30) serving as a fluid machine, both of a compression mechanism (50) and an expansion mechanism (60) are contained in a single casing (31). A shaft (40) coupling the compression mechanism (50) to the expansion mechanism (60) has an oil feeding channel (90) formed therein. Refrigerating machine oil accumulated at the bottom of the casing (31) is sucked up into the oil feeding channel (90) and fed to the compression mechanism (50) and the expansion mechanism (60). The refrigerating machine oil fed to the expansion mechanism (60) is discharged from the expansion mechanism (60) together with the refrigerant after expansion, flows through the refrigerant circuit and then flows back to the compression mechanism (50) in the compression/expansion unit (30).
