  • Patent number: 11982478
    Abstract: An air conditioner includes a refrigerant circuit, sensors that measure an amount representing a state of refrigerant in the refrigerant circuit, and a controller. The controller executes normal operation according to air conditioning load and a first detection operation of detecting refrigerant leakage. The controller adjusts a degree of subcooling at an outlet of the condenser to a first value during normal operation. The controller detects a value related to discharge temperature of the compressor or a value related to degree of superheating at an outlet of the evaporator, based on a sensor measurement result. The controller adjusts degree of subcooling to a second value larger than the first value when executing the first detection operation, and determines that refrigerant is leaking when the value related to discharge temperature of the compressor or the value related to degree of superheating is equal to or larger than a threshold value.

    Abstract: An indoor unit is used in an air conditioner capable of executing a cooling operation by circulating a refrigerant. The indoor unit includes an indoor heat exchanger, a drain pan, a drain pump, and an indoor controller. The indoor heat exchanger (50) exchanges heat between the refrigerant and indoor air. The drain pan receives water generated in the indoor heat exchanger. The drain pump sucks up the water from the drain pan. At a time of executing the cooling operation, the indoor controller operates the drain pump when an evaporation temperature of the refrigerant in the indoor heat exchanger is equal to or lower than a dew point temperature of the indoor air. At the time of executing the cooling operation, the indoor controller controls the drain pump so as to have a period in which operation of the drain pump is not performed when the evaporation temperature of the refrigerant is higher than the dew point temperature.
