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.
