Abstract (en)
[origin: EP3922928A1] A refrigeration apparatus (100) includes an outdoor unit (101) and an indoor unit (102). The outdoor unit (101) includes a first compressor (1), a second heat exchanger (2), a four-way valve (7), and a refrigerant amount adjustment mechanism (10). In a refrigeration mode, the four-way valve (7) connects the first compressor (1) so that a first refrigerant flows in a normal direction in which the first refrigerant flows toward a first expansion valve (3) via the first compressor (1) and the second heat exchanger (2). In a defrosting mode, the four-way valve (7) connects the first compressor (1) so that the first refrigerant flows in a reverse direction in which the first refrigerant flows from the first compressor (1) to the first heat exchanger (4) and returns from the first expansion valve (3) to the first compressor (1) via the second heat exchanger (2). The refrigerant amount adjustment mechanism (10) is configured to adjust a circulation amount of the first refrigerant in the defrosting mode.
