Abstract (en)
[origin: EP4184080A1] An outdoor unit (101) for a refrigeration apparatus having a refrigeration mode and a defrosting mode includes a first refrigeration cycle device (103) configured to circulate a first refrigerant between the first refrigeration cycle device (103) and an indoor unit (102), a second refrigeration cycle device (104) configured to circulate a second refrigerant, and a cascade heat exchanger (11) configured to exchange heat between the first refrigerant and the second refrigerant. The first refrigeration cycle device (103) has a first compressor (1), a second heat exchanger (2), and a four-way valve (7) configured to switch a flow path direction of the first refrigerant between the refrigeration mode and the defrosting mode. The second refrigeration cycle device (104) has a second compressor (9), a third expansion valve (5), and a third heat exchanger (6). The second heat exchanger (2) has an arrangement configuration to absorb exhaust heat of the third heat exchanger (6).
