Abstract (en)
[origin: EP4071425A1] An outdoor unit (2) includes a first channel (F1), a second channel (F2), an erected pipe (71), a flow rate regulation device (73), a refrigerant heating device (75), a dryness increasing device (150), a temperature sensor (122), and a notification device (101). The compressor (10) and the condenser (20) are disposed along a first channel (F1). The second channel (F2) is configured to branch from a branching point (BP1) and return to the compressor (10) the refrigerant having passed through the condenser (20). The erected pipe (71) is provided at the branching point (BP1). The dryness increasing device (150) increases the dryness of the refrigerant that has passed through the condenser (20) in a refrigerant shortage sensing mode to be larger than in a normal mode. The temperature sensor (122) senses the temperature (T1) of the refrigerant after it passes through the refrigerant heating device (75). In the refrigerant shortage sensing mode, in accordance with to an output of the temperature sensor (122), the notification device (101) provides notification of shortage of the refrigerant.
