基于实际建筑环境的人体热适应研究(2)——集中供暖与分户独立供暖住宅对比
Human thermal adaptation in real building environment (2) —Comparison between centralized heating and individual heating in residential buildings
摘要:
对北京的5户集中供暖住户和5户使用壁挂炉的住宅进行了持续一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。结果显示,使用壁挂炉的住宅室内温度比较稳定,平均温度较低,中性温度为18.6 ℃;集中供暖住户中性温度为22.0 ℃;在相同的室内温度下,壁挂炉用户的热感觉投票值较高,对室内环境的接受度也较高。对独立调控对热适应的影响机理和夏热冬冷地区住宅供暖问题进行了讨论。
Abstract:
Conducts a field study in ten residences in Beijing for a whole winter. Among the residences, five are centralized heating (CH) users, and the other five use wall-mounted gas boiler, which is a typical kind of individual heating (IH). Measures indoor environmental parameters, and investigates thermal comfort situation of residents. The results show that the mean indoor temperature of IH residences is stable, and lower than that of CH residences. The neutral temperatures of IH users and CH users are 18.6 ℃ and 22.0 ℃ respectively. Compared with CH users, both thermal sensation and acceptability of indoor environment of IH users are higher at the same indoor temperature. Discusses the influence mechanism of individual control on thermal adaptation and heating of residences in hot summer and cold winter area.
