摘　　要：为了了解我国西北地区新农村住宅冬季室内舒适度状况,研究如何利用当地丰富的太阳能资源来解决农村采暖问题,文章通过试验研究了甘肃省民勤县张麻新村冬季利用太阳能地板进行采暖时新农村住宅的室内舒适度情况,针对采暖期间试验建筑的室内热环境参数和空气品质情况进行了现场测试,并且通过Fanger热舒适指标对新农村住宅的室内舒适度进行了评价。研究结果表明:在室外环境温度高于-7.7℃,全天平均温度高于-2.6℃的晴朗天气条件下,仅在下午16:00以后,利用太阳能地板连续向室内供暖8 h就能保证该新农村住宅各个采暖房间全天的平均温度达到12℃以上,这基本能够满足冬季农村的采暖需求;利用太阳能地板进行采暖能够保证室内具有良好的风环境、湿环境和空气品质。此外,通过计算室内热舒适指标PMVPPD,说明利用太阳能地板进行采暖能够保证室内的舒适度。For the sake of comprehending the indoor comfort conditions of the new rural residential in northwest China, and for the best use of the ample solar in the area to solve the heating problem in winter, an experimental research was carried out to study the indoor thermal comfort in rooms with solar floor heating in winter in a new rural residential in Zhangma village, Minqin county, Gansu province. A field study was conducted during the heating period to record the indoor thermal parameters and indoor air quality, also, evaluated the indoor comfort of the rural residential by Fanger thermal comfort index simultaneously. The results show that in the case of a sunny day, and the ambient temperature is above -7.7 ℃, meanwhile, the average temperature throughout the day is above -2.6 ℃, it can ensured that the indoor temperatures are above 12 ℃ ,after 16：00 in the afternoon, just need to supply heating for 8 hours by solar floor heating, basically can meet the demand of heating in winter. There are good wind environment and humid environment in solar floor heating rooms, as well as the good indoor air quality. By calculating the indoor PMV-PPD index, it explained that there are good indoor comfort in solar floor heating rooms.
