Abstract (en)
[origin: EP4339527A1] When there exists in an outdoor unit a second refrigerant path which enables circulation of refrigerant in the outdoor unit even if circulation of the refrigerant through a first refrigerant path is blocked by closure of a first valve provided in the first refrigerant path which circulates the refrigerant between an indoor unit and the outdoor unit of an air conditioner (1), a signal transmission unit (121) transmits to the outdoor unit, a command signal commanding the outdoor unit to close a second valve which is provided in the second refrigerant path and closure of which blocks the circulation of the refrigerant through the second refrigerant path. A determination unit (123) determines whether the first valve is closed or not after the command signal is transmitted from the signal transmission unit (121) to the outdoor unit.
