PURPOSE:To attain the heating immediately after an engine is started by providing an accumulator between a water cooling type engine and an indoor heat exchanger and changing over to a cooling water circulation between the accumulator and the heat exchanger and to a cooling water circulation between the engine, the accumulator and the heat exchanger. CONSTITUTION:An engine 11, solenoid valves 20, 21, a pump 12 and a radiator 13 constitute a cooling water channel A. The pup 12, an indoor heat exchanger 14, an accumulator 15, solenoid valves 18, 19 from a cooling water channel B. The indoor heat exchanger 14, the accumulator 15, a pump 16 and an solenoid valve 17 constitute a cooling water channel C. A control means which is not shown heats the cooling water channel C according to a heating command mode at the time of the start of the engine. In a heating and engine heating command mode, the engine is also heated by changing over to the cooling water channel B. Thus, the heating immediately after the start of the engine can be attained. |
