Abstract
An air-conditioning apparatus includes: a heat medium circulation circuit including: a heat medium device, a heat medium pipe, a pump, a heat medium detection unit, and a controller that includes a count unit to count an air-conditioning operation time and count a pump operation time based on heat medium detection information of the heat medium detection unit, a storage unit storing a set air-conditioning time and a set pump time, a comparison unit to compare the air-conditioning operation time with the set air-conditioning time and compare the pump operation time with the set pump time, and a device control unit to control driving of the pump so that the pump operation time reaches or exceeds the set pump time when the air-conditioning operation time is longer than or equal to the set air-conditioning time and the pump operation time is shorter than the set pump time.
