Abstract (en)
[origin: EP4089346A1] In a refrigeration cycle apparatus (100), refrigerant circulates in order of a compressor (1), a first heat exchanger (2), a decompressor (3), and a second heat exchanger (4). The refrigeration cycle apparatus (100) has a refrigerant container (5), a first switch unit (6), a second switch unit (7), and a controller (10). When a first condition meaning that an amount of refrigerant in liquid state stored in the refrigerant container (5) is excessive is satisfied, the controller (10) controls the first switch unit (6) to guide the refrigerant from the compressor (1) to the first heat exchanger (2) through the refrigerant container (5) and controls the second switch unit (7) to guide the refrigerant from the second heat exchanger (4) to the compressor not through the refrigerant container (5). When the first condition is not satisfied, the controller (10) controls the first switch unit (6) to guide the refrigerant from the compressor (1) to the first heat exchanger (2) not through the refrigerant container (5) and controls the second switch unit (7) to guide the refrigerant from the refrigerant container (5) to the compressor (1).
