摘要
对焦作地区热计量住宅的地暖及散热器用户进行了持续2个供暖季的现场调查,测量了室内热环境参数,并调查了居民的热舒适状况。通过对比分析发现地暖和散热器用户的服装热阻、热感觉及热期望反应均具有统计学上的显著意义。与散热器末端相比,地暖用户拥有较低的热中性温度及可接受温度下限。采用地暖末端提高了人们对低温环境的接受度,同时降低了对高温环境的期望。在满足人体热舒适的同时,地暖末端还可节省供暖能耗。以PMV为评价指标的国际标准并不完全适用于我国分户热计量采暖建筑。本研究为采暖末端的选择以及室内热环境的参数设计提供了参考。
A thermal comfort field study of heat metering residential buildings with floor heating(FH)terminal and radiator(RH)heating terminal was conducted in Jiaozuo,Henan Province,for two consecutive heating seasons.The indoor environmental parameters were measured,and the thermal comfort of residents were also investigated.The analysis and comparison results show that the clothing insulation,thermal sensation,and thermal expectation reaction of FH and RH’s terminal users all have statistical significance.FH terminal users have a lower thermal neutral temperature and lower limit of acceptable temperature.The adoption of FH terminal has improved people’s acceptance of low-temperature environment and lowered people’s expectation for high-temperature environment.The FH terminal can meet people’s needs for thermal comfort while saving energy.The international standard based on PMV as the evaluation index can not be fully applicable to the field study of thermal comfort of heat metering buildings in China.
