AIR-CONDITIONER, AIR-CONDITIONING SYSTEM, AND METHOD FOR MONITORING AIR-CONDITIONER

Provided is a method for monitoring an air-conditioner having a semi-conductor gas sensor, comprising: 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 (S1200, S1300, S2400); starting...

More Information
Summary:Provided is a method for monitoring an air-conditioner having a semi-conductor gas sensor, comprising: 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 (S1200, S1300, S2400); 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 (S1200, S1400, S1800); stopping the provisional operation of the fan (S1800); 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 (S2100, S2400); 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 (S2400).
