PURPOSE:To reduce variation in the blow-off temperature thereby enhancing comfortableness by delaying a predetermined time after stopping the heating of a heat medium to stop a heat medium circulating machine and suppressing an indoor blower to less than a set air quantity or stopping the same, in the titled air conditioner with a heat medium heater being attached. CONSTITUTION:During a normal operation, a thermostat 5 is closed on the ''Low'' side, and a heat medium heated by a heat medium heater 1 returns to a circulator 2. The heat medium is, then, discharged, passing through an indoor heat exchanger (not shown), and is radiated. When the room temperature rises and the thermostat 5 is closed to the ''High'' side, the heater medium heat 1 stops instantaneously, and a delay timer 6 operates. After the lapse of a predetermined time, the contact between a point C and a point D is opened, and a heat medium circulatory 2 and an indoor blower 4 stop their operations. When the temperature lowers and the thermostat 5 is switched, the heater 1 is operated again. Such operations are repeatedly carried out. By this construction, the variation width of the blow-off temperature can be made small and comfortableness can be improved. |
