Abstract

See full text

A method monitors an air-conditioner having a semi-conductor gas sensor, the method including: determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a first threshold when the fan is in operation; starting operation of the fan as a provisional operation if the detection value is equal to or greater than a second threshold when the fan is not in operation; stopping the provisional operation of the fan; determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a third threshold after stopping the provisional operation of the fan; and taking a predetermined action for outputting alarm information and/or limiting supply of refrigerant to the heat exchanger when a refrigerant leakage is determined to have occurred.
