Abstract
A defrosting control method wherein an indoor unit determines whether a drop in the temperature gradient of an indoor side heat exchanger has been caused by a heavy load protecting operation or frosting of the outdoor heat exchanger during a reverse cycle heating operation of a two-unit-type air conditioner. The defrosting control is not triggered when the heavy load protecting operation is being carried out, and the defrosting control is started when predetermined conditions are satisfied, including the temperature of the indoor heat exchanger being below a raised predetermined temperature during a heavy load protecting operating.
