Title:
AIR CONDITIONER AND METHOD FOR CONTROLLING AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/171483
Kind Code:
A1
Abstract:
An air conditioner having a refrigerant detection sensor with which a leakage of refrigerant can be detected properly even when a leakage detection level (detection threshold value) of the refrigerant detection sensor fluctuates due to a deterioration over time in the leakage detection sensor or the surrounding environment where the leakage detection sensor is installed. The air conditioner 1, which circulates between an indoor unit 10 and an outdoor unit 20 a refrigerant R used for exchanging heat, is configured so as to have a refrigerant detection sensor 30 that detects a leakage of the refrigerant R, and a determination value correction unit 114 that, in accordance with a sensor detection value C from the refrigerant detection sensor 30, corrects an initial determination value Cjo (detection determination value) with which the refrigerant detection sensor 30 detects leakage of the refrigerant R.
