Abstract

The thermodynamic characteristics of a compact thermoelectric (TE) air conditioner were investigated from a perspective based on exergy. A new efficiency is developed that is useful in studying TE performance resulting in possible improvement. Exergy analysis is applied to a TE system and its components, and exergy flows and efficiencies are evaluated. It was found that the exergy decreased as the electric current supplied to the TE air conditioner increased. Maximum exergy efficiency was 0.088 with a corresponding cooling capacity of 28.6 W. The exergy efficiency of the compact TE air conditioner was found to be relatively very low when compared with the respective coefficient of performance. ฉ 2013 TMS.
