Abstract (en)
[origin: EP4012293A1] A refrigeration cycle apparatus (100) includes a compressor (1), a first heat exchanger (2), a second heat exchanger (4), an expansion valve (3), a flow rate adjuster (130), and a controller (10). The flow rate adjuster (130) adjusts an amount of refrigerant flowing per unit time through at least one of the first heat exchanger (2) and the expansion valve (3). An operation mode of the refrigeration cycle apparatus (100) includes an activation mode and a normal mode. The activation mode is executed when the compressor (1) is activated. The normal mode is executed after the activation mode. In the normal mode, the refrigerant circulates in a first circulation direction in which the refrigerant flows sequentially through the compressor (1), the first heat exchanger (2), the expansion valve (3), and the second heat exchanger (4). The controller (10) controls the compressor (1) and the flow rate adjuster (130) to reduce the amount of refrigerant flowing per unit time through at least one of the first heat exchanger (2) and the expansion valve (3) in the activation mode to be less than the amount of refrigerant in the normal mode.
