|
摘要
研究了夏季室温26和28℃温控床垫在20、23、26及29℃4个调节水平时,人与床垫接触界面温度、被褥微环境温度和主观热反应方面的差异性,以及获得温控床垫适宜的温控范围。结果表明,温控床垫部分调节水平之间存在显著差异,两种室温时,温控29℃分别与23和20℃存在显著差异。室温26℃温控23和26℃时,被覆躯体处于舒适水平,室温28℃温控20℃时,被覆盖躯体处于中性水平。室温26和28℃,接触界面舒适的温度分别为31.9～32.5℃和32.3～32.8℃;被褥微环境舒适的温度分别为31.45～32.00℃和31.8～32.35℃;床垫适宜的温控范围分别为21.6～24.6℃和18.3～20.5℃。
In this paper, a study was conducted on the differences in the mean human-mattress interface' temperature(MIT), mean bedding microclimate temperature(MBT) and subjective thermal reaction under the indoor air temperature of 26℃ and 28℃ in summer, when the temperature-controlled mattress was regulated at four levels: 20,23, 26, and 29℃, to aim at obtaining the suitable ranges of temperature control for the mattress. The results indicated that significant differences were observed between some adjustment levels. At 26 and 28℃, significant differences were found in 29℃ as compared to 23 and 20℃, respectively. At 26℃, the covered body was comfort in 23 and26℃; At 28 ℃, the covered body remained neutral in 20℃. At 26 and 28℃, the comfortable MIT were 31.9-32.5℃and 32.3-32.8℃, respectively; the comfortable MBT was 31.45-32.00℃ and 31.8-32.35℃, respectively; the priate temperature control ranges were 21.6-24.6℃ and 18.3-20.5℃, respectively.
