PURPOSE:To simplify a car that uses a ceramic engine by guiding the heating medium heated by exhaust gas to a heater core and providing a turbo compressor whose refrigeration cycle is driven by an exhaust turbine. CONSTITUTION:A branch section 4 is provided downstream from the exhaust manifold 3 of a ceramic engine 1 and the exhaust mainfold 3 is branched into the exhaust manifold main pipe 5 and a heat medium heater 6 that houses a heat medium coil 15. In addition, the second branch section 9 is provided downstream from the exhaust mainfold main pipe 5 and a bypass pipe 10 that makes a detour around an exhaust turbine 11 is connected to the branch section. A turbo compressor 22 is provided on the same axle of the exhaust turbine 11, and the coolant compressed here is guided to an evaporator 21 in an air conditioning housing 16 through a condenser 24 and an expansion valve 23 during cooling operation. Furthermore, during heating operation, an exhaust damper 8 is controlled and a part of exhaust gas is guided to a coolant heater 6. The heat medium in a heat medium coil 15 is heated and guided to a heater core 29. |
