ABSTRACT:
The present invention provides a system for controlling the climate of a hybrid vehicle. The system includes a thermoelectric module, a heat exchanger, a pump, and a valve. The thermoelectric module includes thermoelectric elements powered by electric energy. The thermoelectric elements emit or absorb heat energy based on the polarity of the electrical energy provided. A tube containing coolant runs proximate the thermoelectric elements. To aid in the transfer of heat energy, a blower is provided to generate an air flow across the thermoelectric elements and the tube. The coolant is provided from the thermoelectric module to a heat exchanger that heats or cools the air flow provided to the cabin of the vehicle. The pump and valve are in fluid communication with the heat exchanger and thermoelectric module. The pump pressurizes the coolant flow through the tube and coolant lines. In a cooling mode, the valve is configured to selectively bypass the engine coolant system of the vehicle.
