摘　　要：湖南西部(湘西)属于夏热冬冷地区。此地区的农村居民在其住宅中使用传统供暖设备(火桶)抵御冬季寒冷气候。本研究目的在于了解湘西地区在住宅中使用火桶的农村居民的冬季热舒适情况。通过对空气温度、平均辐射温度、风速、相对湿度、一氧化碳浓度等室内环境参数进行了测量,以问卷方式调查了107名受试者的热舒适状况。调查结果表明使用火桶使人在极端环境中仍能保持舒适状态,被调查人员的中性温度可低至11.49℃,可接受温度区间的下限为7.82℃。同时,使用火桶能使人适应更高的风速,也缓解了湿冷环境中人的潮湿感觉。然而使用火桶时仍会产生一氧化碳,未来仍需研究进一步探讨火桶的安全性。Western Hunan Province（ West Hunan） is located in the hot-summer and cold-winter area. Rural residents in this area use a kind of traditional heating equipment（ warm-barrel） for heating in winter. This survey aims to study the comfort condition of residents in rural residential buildings in the west of Hunan Province,China.We measured the indoor environment parameters like air temperature,black global temperature,air speed,relative humidity,and CO concentration. Meanwhile,questionnaires were conducted with 107 subjects participating in.The obtained results showed that the warm-barrel well maintained occupants ＇ comfort when they were under extreme situations in winter. The neutral temperature of local residents investigated was 11. 49 ℃,and the lower limit of acceptable temperature was as low as 7. 82 ℃. Besides,using the warm-barrel helped the occupants to adapt to high wind speeds and high humidity level. However,use of warm-barrel will still produce carbon monoxide. The future remains to be further study the security of warm-barrel.
