Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/116437
Kind Code:
A1
Abstract:
An air conditioner comprises a refrigerant circuit in which a refrigerant circulates, a refrigerant detection sensor that detects refrigerant leaks, and a control unit that controls the refrigerant circuit. In a situation where replacement of the refrigerant detection sensor is required by a first time period (T1) elapsing, the control unit issues a notification to an air conditioning control terminal when a second time period (T2) shorter than the first time period (T1) elapses, and if an abnormality in the refrigerant detection sensor is detected after the first time period (T1) elapses and a prescribed time period (Tc) elapses, the control unit forcibly stops air conditioning operation.
