An analytical study was conducted to determine the feasibility of employing thermoelectric (TE) cooling technology in automobile airconditioners. The study addressed to key issues - power requirements and availability of thermoelectric materials. In this paper, a mathematical model was developed to predict the performance of TE airconditioners and to analyze power consumption. Results show that the power required to deliver a cooling capacity of 4 kW (13,80 Btu/h) in a 38(degree)C (100(degree)F) environment will be 9.5 kW electric. Current TE modules suitable for air conditioning are made of bismuth telluride. The element tellurium is expected to be in short supply if TE cooling is widely implemented for auto air conditioning; some options available in this regard were studied and presented in this paper.
