Abstract: PURPOSE:To make the temperature in the room substantially uniform by a method wherein a first indoor heat exchanger or a second indoor heat exchanger is made to serve as a condenser or an evaporator selectively and air blasts on the sides of the condenser and the evaporator are directed toward the lower part and the upper part, respectively, of the room. CONSTITUTION:An electromagnetic valve 23 is opened, a burner 12 is operated and an electromagnetic valve 10 is also opened. A coolant is heated to vaporize by a coolant heater 6 and the vaporized coolant is sucked into, and discharged from, a compressor 7 to reach the second indoor heat exchanger 20 and the first indoor heat exchanger 18 and the room is heated by operating blowers 19 and 21.
