An air conditioning apparatus cools air sent to a passenger compartment (1) by using a cooling machine (2) which is a vapor compression heat pump. Heating of the air may be implemented by utilizing the heat of an internal combustion engine (7) or via a Peltier element (16). As the cooling machine (2), a cooling machine provided in a conventional air conditioning apparatus may be utilized, thus eliminating the need for significant modification of the structure of the air conditioning apparatus. The air sent to the passenger compartment (1) can be heated with the Peltier element (16) so that the passenger compartment (1) can be air-conditioned (heated), even when it is difficult to utilize the internal combustion engine (7) as a heat source for air-conditioning the passenger compartment (1), such as when the vehicle is travelling solely on the motor generator. Thus, the passenger compartment can be air-conditioned in vehicles in which it is difficult to utilize the internal combustion engine (7) as a heat source for air-conditioning the passenger compartment, without requiring significant structural changes. |
