摘要:
为缓解高温环境下劳动人员面临的热害问题，设计1种利用半导体制冷片作为制冷源的便携式冷循环降温服，并在高温环境下测试其降温性能。结果表明：在总电源功率100 W、环境温度30 ℃的情况下，运行12 min后，制冷水温度降低至15.7 ℃。降温服稳定运行状态下制冷功率为340.4 W。系统运行环境温度对制冷系统的制冷性能有显著影响；相同功率的情况下，双面制冷系统的COP是单面制冷的1.30倍，且其制冷性能受环境温度影响更小；利用水循环散热能显著地改善制冷系统的散热性能，提高制冷系统的制冷性能。
Abstract:
In order to alleviate the problem of heat hazard confronted by the workers in high temperature environment,a portable cooling garment with cold circulation by using the semiconductor refrigeration plate as refrigeration source was designed,and its cooling performance was tested in high temperature environment.The results showed that after operating for 12 minutes under the conditions of 100 W total power and 30 ℃ ambient temperature,the temperature of refrigeration water was reduced to 15.7 ℃.The refrigeration power of the cooling garment under the stable operating conditions was 340.4 W.The ambient temperature of system operating had significant influence on the refrigeration performance of the refrigeration system.Under the same power,the COP of the double-side refrigeration system was 1.3 times as that of the single-side refrigeration system,and its refrigeration performance was less affected by the ambient temperature.The water circulation heat dissipation could significantly improve the heat dissipation performance and refrigeration performance of the refrigeration system.
