一种利用半导体热电效应的空调床的性能研究及其评价

Research and Evaluation for a Bed Air-conditioner by Semiconductor Thermoelectric Effect

为了降低夜间空调能耗,基于帕尔帖效应设计了一种床体局部空调,简称空调床。空调床由床头制冷装置和床尾供暖装置构成,在满足床内舒适温度需求的同时,可以实现"头凉脚暖"的局部温度场。测试结果表明:冬季空调床维持床内温度为22℃时,功率为0.1kW^0.2kW,脚部空气温度比头部约高6℃;夏季当室温低于30℃,床内维持28℃时,功率为0.06kW至0.12kW,脚部空气温度比头部约高1.5℃。此外,通过系统模拟分析可知,一定条件下,空调床的使用可在冬季夜间节约空调耗电约52%,夏季节约42%。

In order to reduce energy consumption of air-conditioner during night, one zoning air-conditioner fixed on the bed, namely bed AC, is developed based on peltier effect. The bed AC is equipped with a heating unit on the foot part and a cooling unit on the head part. It not only meets the thermal comfort of a bed, but also can create a comfortable environment about ＂warm foot and cool bead＂. In winter, bed AC can maintain bed air temperature at 22℃, and its power is about 0.1 kW-0.2kW, and foot air temperature is approximately 6℃ higher than that of head. In summer, if room temperature is lower than 30℃bed AC can keep bed air temperature at 28℃, and its power varies from 0.06kW to 0.12kW, and head air temperature is nearly 1.5 ℃ lower than that of foot. By system simulation, the energy-saving performance is also studied. It can be found that energy saving rate of bed AC in winter and summer sleeping time is 52% and 42% respectively, compared with traditional split air-conditioner.
