<p>PURPOSE:To improve the heating efficiency by arranging an engine heat utilizing heater in a car room, opening the exhaust side of a turbo-heater constituted of an exhaust turbine and a temperature increasing blower into the car room, and turning the turbo-heater on or off based on the engine temperature. CONSTITUTION:The temperature of an engine 1 is detected by a temperature sensor 26 and inputted to a control valve control means 60. On the other hand, an engine heat utilizing heater 23 circulates the heat cooling water from the engine 1 and heats a car room 14. A control valve control means 60 opens control valves A and B when its input detection engine temperature is the preset temperature or below and drives an exhaust turbine 7 and operates a blower 8, the hot air from the engine 1 is flown into the car room 14 via a hot air passage 18. At the preset temperature or above on the contrary, the control valves A and B are closed to stop a turbo-heater 4. Heating can be efficiently performed according to this constitution.</p> |
