Abstract

A vehicle air conditioner for a passenger compartment includes a power source, a radiator provided outside the passenger compartment, a heat medium passage through which heat medium is circulated between the power source and the radiator, a first peltier module having a first peltier device and a first heat exchanger, and a second peltier module having a second peltier device and a second heat exchanger. The first and second peltier devices each has a first surface and a second surface, one of the first surface and the second surface serves to release heat, the other of the first surface and the second surface serves to absorb heat. The first heat exchanger is thermally coupled to the first surface. The second heat exchanger is thermally coupled to the first surface. The heat medium passage is thermally coupled to the second surfaces of the first and second peltier devices.
