Abstract
PURPOSE: To suppress the generation of a cold draft of an air conditioner that uses refrigeration cycles, by minimizing the decrease of temperature in the space used during the defrosting operation of a heat source side heat exchanger.
CONSTITUTION: When frost forms on a heat exchanger in a heat source side unit 2, a deicer 204 is actuated to start defrosting operation and at the same time to initiate a timer 109 through a relay 108 in a use side unit 1. The timer 109, while retaining its function, energizes a relay 100, turns on an auxiliary heater 103, and switches over a fan motor 102 to a low velocity tap side to minimize its velocity. The relay 110 can also be energized by a thermostat 111 which detects the blow-off temperature decrease or the use side heat exchanger temperature decrease. Thus, for the defrosting for a relatively short period the timer 109 can suppress a cold draft, while for the defrosting for a relatively long period the thermostat 111 can be switched on to suppress a cold draft.
