AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2019078440
Kind Code:
A
Abstract:
To provide an air conditioner that can be operated at high efficiency.SOLUTION: An air conditioner includes: a compressor 101 driven by an engine 100; a bypass pipe line 404 for bypassing a refrigerant flowing out from an outdoor heat exchanger 104 to a suction side of the compressor 101; flow rate control means 107 for restricting a flow rate of the refrigerant in the bypass pipe line 404; an oil separator 102; an oil return pipe line 405 for returning separated oil to the suction side of the compressor 101; a first temperature sensor 301 for measuring a temperature of the refrigerant on the discharge side; and decompression means 108 and a second temperature sensor 302 that are provided in the oil return pipe line 405 in this order from the connection side to the oil separator 102. When a difference between values of the first temperature sensor 301 and the second temperature sensor 302 increases, the flow rate of the refrigerant in the bypass pipe line 404 is reduced.SELECTED DRAWING: Figure 1
