Hot and humid environments are ubiquitous in some special workplaces, such as deep mines, aviations, and military territories. High–temperature radiation is a serious threat to the health of high temperature operation personnel. Exposed to high temperatures for a long time will inevitably lead to dehydrations, heatstroke, or even death. Based on the particularity of the hot work environment, as well as the principle of thermoelectric refrigeration, the related properties of semiconductor cooling garments was studied, which provided some basis for further design. To determine the optimal working conditions of cooling garment with the help of a water–cooled radiator, voltage from 0 to 12 V was adopted to find the optimal voltage. Meanwhile, the refrigeration performance was tested for different mass flows and heat–dissipating methods. The studies showed that for two water different radiators, the aluminum water–cooled radiator was viewed as the optimal choice for the refrigeration garment. For the semiconductor refrigeration garment, there was an optimal working voltage of 2 V. Among these four different mass flows, the flow of 0.0056 kg/s was the optimal choice under the experimental conditions. Among these four different combinations of cooling methods, the effect of a combination of water cooler and radiating film was the best, whereas the combination of water cooler and fan was the worst, however, water cooling was second to none under the experimental conditions.
