PURPOSE:To make it possible to perform a comfortable heating operation and which has a small heat loss by a method wherein a condenser and an evaporator in a cooling cycle are provided in the room and the upper part of the room is cooled while the lower part of the room is heated by utilizing warm air in the upper part of the room. CONSTITUTION:An electromagnetic valve 10 is opened to cause a burner 20 to operate and an electromagnetic valve 17 is also opened. A coolant is heated to vaporize by a coolant heater 13, the vaporized coolant is sucked into, and discharged from, a compressor 14 to reach a second heat exchanger 7 and a first heat exchanger 5 and by operating blowers 6 and 8, the room is heated. When the temperature in the upper part of the room reaches a predetermined value, the electromagnetic valve 10 is closed and the combustion of the burner 20 is stopped. As a choking resistor is inserted in the coolant, the second heat exchanger acts as a condenser and the first heat exchanger 5 acts as an evaporator. In this case, an air blast by a blower 6 is directed upward in the room 2 and that by a blower 8 is directed downward so that the temperature distribution in the room is substantially equalized. |
