哈尔滨地区冬季农宅热舒适现场调查

Field survey on indoor thermal comfort in rural houses around Harbin in winter

对哈尔滨近郊2个村10户农宅的冬季室内热环境与居民的热舒适进行了现场调查。结果显示,冬季农宅的平均室温为12.3℃,但热环境可接受率高达92%;农民的热中性作业温度为14.4℃,90%可接受的作业温度下限为8.8℃;农民通过行为调节、心理期望等适应偏冷的热环境,导致其热中性温度与可接受的温度较低。对于分散式农宅,建议采用传统的火炕分散供暖方式。建议采用作业温度作为严寒地区冬季农宅室内热舒适的评价指标。

Conducts a field study on thermal environment and thermal comfort in ten rural houses in two villages around Harbin.The results show that the average indoor air temperature is 12.3 ℃,but the thermal acceptability can reach to 92%.The thermal neutral operative temperature is 14.4 ℃,and the lower limit of acceptable operative temperature is 8.8 ℃.The peasants get accustomed to the thermal environment by behavioral adjustment and psychological acclimatization,etc.Their thermal neutral temperature and acceptable temperature are comparatively low.For decentralized rural houses,suggests the traditional heating mode by the Chinese Kang.Suggests using the operative temperature as the evaluation index of indoor thermal comfort for rural houses in severe cold zone in winter.
