摘要： PURPOSE: To secure heat capacity required for defrosting as well as to eliminate disconfort from exposure to cooled air blown out by a method wherein during defrosting procedure, an air blower remains operated until temperature of air blown out reduces to a temperature not more than a predetermined value, then the blower is turned OFF.
CONSTITUTION: A set of contacts 4 of a contactor and an exciting coil 5 are switched to a set of contacts 21 of auxiliary relay and its exciting coil 22, then the set of contacts 4 of the contactor is connected between the lower temperature position of a tow-stage temperature controller 13 and an exciting coil 15. On the other hand, the exciting coil 5 is to be opened upon the temperature of additional air blow-out being reduced to a predetermined temperature or lower. A thermostat 23, a set of contacts of an auxiliary relay 7 and a set of contacts 16 of an auxiliary relay are 7 and a set of contacts 16 of an auxiliary rely are connected in parallel to an exciting coil 22. During defrositing in heating status, temperature of air blown out connot be reduced to the set temperature of the thermostat 23 for a while by the effect of heat capacity of an indoor heat exchanger even after the heat exchanger is switched from a condenser to an evaporator, so that discomfort from exposure to air blown out can be eliminated.
