Abstract
PURPOSE: To prevent the abnormal rise in the temperature of the coolant and pressure increase thereof generated at the time of heating the coolant by controlling the quantity of air sucked by an indoor fan.
CONSTITUTION: A voltage of a heat sensitive element 12 provided on the inflowing air inlet side of a heat exchanger 3 with respect to a voltage of a heat sensitive element 11 provided in a coolant pipeline of an indoor side heat exchanger 3, is supplied to a comparator 15. The difference between these voltages is supplied as a reference voltage to a frequency converter 16 to vary the power source frequency to vary the rotational speed of a fan motor 8.
