Abstract
An air-conditioning apparatus prevents a compressor from not starting for a long time when an actual air conditioning load is low or when exhaust heat from heat-generating devices in an air-conditioned indoor space is not returned to an indoor unit, and reduces the number of times the compressor is started and stopped. The air-conditioning apparatus includes a refrigerant circuit sequentially annularly connecting the compressor, a heat source-side heat exchanger, an expansion valve, and a use-side heat exchanger, a blowing temperature sensor detecting a blowing temperature of air brown into the air-conditioned indoor space after passing through the use-side heat exchanger in the indoor unit including the use-side heat exchanger, and a compressor control unit performing thermo-on and thermo-off controls to start and stop the compressor, to approximate the blowing temperature detected by the blowing temperature sensor to a preset temperature. A time for which the next thermo-on control is prohibited is set based on an air-conditioning operation state immediately preceding the thermo-off control or during thermo-off time.
