<P>PROBLEM TO BE SOLVED: To provide a vehicle air conditioner that efficiently generates power using a Peltier element for air conditioning, such as cooling and warming the inside of the vehicle. <P>SOLUTION: A second power generation mode is performed when the temperature difference between the outside air around a radiator 6 and the inside of the vehicle 7 is small, and the power cannot be effectively generated using the Peltier element 2 based on the temperature difference. In the mode, the power is generated using the Peltier element 2 based on the temperature difference between the outside air around the radiator 6 and cooling water passing an outdoor heat exchanger 15. The outdoor heat exchanger 15 is provided in a place where the temperature difference between the outside air around the radiator 6 of a first circulation circuit 3 and the cooling water passing the outdoor heat exchanger 15 of a second circulation circuit 12 is large. Thereby, the power is efficiently generated using the Peltier element 2 based on the temperature difference. <P>COPYRIGHT: (C)2013,JPO&INPIT |
