Abstract:
1. An air conditioning method, comprising: when a refrigerant circuit is in operation, a refrigerant circuit compressor is on, and a temperature of an evaporator of the refrigerant circuit is lower than a temperature of a heat exchanger of a heating circuit, transferring heat from the heat exchanger to air passing from the evaporator through the heat exchanger; when the refrigerant circuit is not in operation, the refrigerant circuit compressor is off, and the temperature of the evaporator is higher than the temperature of the heat exchanger, transferring heat from the air passing from the evaporator through the heat exchanger to the heat exchanger; and when the refrigerant circuit is not in operation and when a desired temperature of a passenger cabin is above a current temperature of the passenger cabin, transferring heat from the heat exchanger to air passing from the evaporator through the heat exchanger.
