PURPOSE:To improve comfortableness and prevent faults of heat medium circuit parts by continuing blowing of air at a predetermined air feed quantity until the blow-off temperature becomes less than a predetermined temperature after the indoor thermostat detected a predetermined high temperature, in the titled air conditioner with a heat medium heater being attached. CONSTITUTION:During a normal operation, an indoor thermostat 5 is closed to the ''low'' side, and the heat medium is heated by a heater 1 and returns to a compressor 2. The heat medium is, then, discharged and dissipated by the indoor heat exchanger (not shown). When the indoor temperature increases and the thermostat 5 is changed over to the ''High'' side, the heat medium heater 1 immediately stops and a delay timer 8 operates. With the lapse of the time set in the timer, the contacts C-D are opened to stop the operation of the compressor 2. During this time, a blow-off temperature sensor monitors the blow-off temperature, and the blow off temperature becomes less than a predetermined temperature, and the blowing of air by the blower 4 is continued until an electromagnetic switch Ry is opened. |
