Thermoelectric effect, which induces heat flow through thermoelectric (TE) materials by electric current, is widely used in niche cooling application and was not able to penetrate the HVAC&R industry due to performance limitation at high temperature lift conditions. Thermoelectric cooling is an environmentally benign technology; it eliminates the need for refrigerant flow in the system. Furthermore, the system involves solid state operation with no moving parts except for fans; hence quiet operation. These desirable characteristics spurred the need for continuous research to widen TE application in the HVAC&R. This seminar presents recent developments in thermoelectric cooling technology and potential HVAC&R system efficiency improvements. The topics covered include a hybrid vapor compression cycle - TE system for cold climate operation, a high performance thin film thermoelectric device, and optimal design methodology of TE for cost effective cooling, heating and power.
