摘要： An air conditioner equipped with a heat medium circulation circuit in which a heat medium circulates and in which a heat medium device and heat medium piping that are formed of a metal material are connected by means of a connection member that includes a different metal material, and a pump that is provided in the heat medium circulation circuit and is for circulating the heat medium, said air conditioner being provided with a heat medium detection means for detecting a state of the circulating heat medium, and a control device for controlling the pump in accordance with whether the heat medium is flowing. The control device has: a count unit for counting an air-conditioning operation time, and counting a pump operation time on the basis of heat medium detection information from the heat medium detection means; a storage unit for storing a set air-conditioning time and a set pump time; a comparison unit for comparing the air-conditioning operation time and the set air-conditioning time, and the pump operation time and the set pump time; and a device control unit for controlling driving of the pump such that the pump operation time is greater than or equal to the set pump time, when the air-conditioning operation time is greater than or equal to the set air-conditioning time and the pump operation time has not reached the set pump time.
