Experimental Study on the Overlap Effect of Thermoelectric Cooling Garment

Abstract

In recent years, high temperature is increasingly frequent, which has a serious effect on the health of workers. Thus, it is necessary to develop a cooling garment to improve work conditions. The cooling performance of thermoelectric cooling garment is experimentally investigated in the paper. The studies show that: under working conditions of only one element of thermoelectric cooler, the temperature is basically equal at the same radius as the center of P0, and as the distance increases, the temperature difference of each measuring point reduces rapidly first and then slows down; under working conditions of three elements of thermoelectric cooler, the temperature exhibits some differences, and as the distance increases, the measuring point temperature difference of P5-P8 and P9-P12 first decrease and then rise, which has a significant turning point at the distance of 3cm; the overlap effect scope of thermoelectric cooling garment is a circle, the radius of 4cm at the center of P0, and at the same distance of two adjacent elements of thermoelectric cooler, the overlap effect is more obvious when the cooling center is located in the same horizontal line. This study provides some guidance for the application of thermoelectric cooling garment.
