The optimization of permeable thermoelement for thermoelectric air conditioner unit based is presented. In the thermoelectric air conditioner unit the air flow is cooled due to a combined action of thermoelectric effects and the Joule-Thomson effect. Methods for calculation of temperature distribution, determination of power conversion energy characteristics and thermoelement design in maximum COP mode are discussed. Results of computer studies for the case of thermoelement legs based on Bi2Te3 material have shown the possibility of COP increase by a factor of 1.6-1.7 as compared to conventional thermoelectric systems.
