Abstract
An air-conditioning apparatus includes; a first heat source device configured to transfer heat to process air using as a heat source a vapor-compression refrigeration cycle; a second heat source device configured to transfer heat to the process air using an other heat source different from the vapor-compression refrigeration cycle; and a controller configured to control the first heat source device and the second heat source device. The controller deactivates the first heat source device and activates the second heat source device when, during a period in which the first heat source device is being operated to heat the process air, a temperature of the heated process air is kept at a target temperature and a parameter indicating an energy consumption of the first heat source device exceeds a first threshold value.
