摘要

设计了一款空气冷却式降温服，并确定其冷却功率及进出口空气的状态参数和流量，同时计算了空气冷却式降温服用半导体制冷装置所需的制冷功率。对半导体制冷装置进行实验和数值模拟，通过实验数据验证了数值模拟计算模型的准确性，并提出优化方案。采用验证过的数值模拟计算模型对半导体制冷装置进行优化设计与计算，优化后半导体制冷装置在干球温度为34.4 ℃、湿球温度为27.9 ℃的环境中可提供流量和温度分别为6.283?10-3 m3/s和 29 ℃的冷风，符合空气冷却式降温服的设计要求。

Abstract

Air-cooled garments are designed and the cooling capacity

state parameters

and flow rates of the air inlet and outlet are determined. The refrigeration capacity required by the cooling device matching that of the garment is calculated. Experimental and numerical simulations of a thermoelectric refrigeration device are conducted. The accuracy of the simulation results is verified by comparing the experimental data with the simulation results. An optimization scheme for refrigeration devices is proposed. The thermoelectric refrigeration device is optimized by validated numerical simulation calculation models

which can provide 6.283×10-3 m3/s of cold air at 29 ℃ for a garment under the dry bulb temperature of 34.4 ℃ and wet bulb temperature of 27.9 ℃

and the device can meet the design requirements of the air-cooled garment.
