Abstract

PURPOSE:To contrive to shorten the rising-up time of a heating operation and enhance comfortableness, by changing over a heater capacity at the time of rising-up of a heating operation and at the time of a steady operation, in an air conditioner used combinedly for cooling and heating by jointly using an electric heater at the time of heating. CONSTITUTION:At the time of starting a heating operation, an output from a controlling part 13 is fed to a relay switch 7 for controlling a compressor 8 to operate the compressor 8, an output and is fed to a relay switch 11 for controlling the heater capacity to connect a high-capacity tap 11a. In addition, an output is fed to a relay switch 5 for controlling the electric heater 12 fitted with a capacity changing-over tap to operate the heater 12 with a high capacity, and an output is fed to a relay switch 9 to operate a room-side blower 10. Thereafter, when the heating operation is progressed and room temperature reaches a predetermined value, the relay switch 11 is connected to a low-capacity tap 11b an output from a temperature detector 4, and the heater is operated with a low capacity.
