摘要
通过对新建被动式太阳房及相同结构的对比房室内温度及室外温度、太阳辐照度等参数的监测,研究了寒冷季节室内温度随室外气象条件以及太阳辐照度的变化情况。通过分析发现,在室内无热源及辅助热源条件下,太阳房室内平均空气温度比对比房室内平均空气温度高7.2℃,最高温差达18.3℃,最低温差0.3℃。通过对太阳房供暖节能率ESF分析计算得出太阳房供暖保证率较高,证明了在此建立被动式太阳房建筑的可行性和经济性。
This experimental project was built in high elevation, high severely cold Qinghai-Tibet Plain area. Through monitoring the data of newly built passive solar house and the contrast house with same stucture, such as room temperature, outdoor temperature, the solar radiation in cold season, etc., the change of room temperature along with ambient meteorological condition and the solar radiation was investigated in this paper. The results show that the average air temperature in solar house was higher than in the contrast house by 7.2℃ when there were not the assistant heat sources in the room, and the maximum temperature difference reaches 18.3 ℃, the lowest temperature difference was only 0.3 ℃. Through ESF analysis computation for heating energy conservation rate, it was found that the solar fraction of passive solar house heating is high. It shows the feasibility and economics of establishing passive solar house in this area.
