Abstract (en)
[origin: WO2022239072A1] In the present invention, if an outdoor unit of an air conditioner (1) includes a second refrigerant path, which is capable of circulating a refrigerant within the outdoor unit even if the refrigerant circulation in a first refrigerant path for circulating the refrigerant between an indoor unit and the outdoor unit is blocked by the closing of a first valve disposed in the first refrigerant path, a signal transmission unit (121) transmits, to the outdoor unit, an instruction signal instructing the outdoor unit to close a second valve which, upon closing, blocks the refrigerant circulation in the second refrigerant path. A determination unit (123) determines whether the first valve is closed after the instruction signal has been transmitted from the signal transmission unit (121) to the outdoor unit.
