Experimental research on the indoor thermal environment of the office buildings with solar energy heating in Xinjiang, China

In order to study the indoor thermal environment of solar heating of office buildings in Xinjiang, A rural office building in Shihezi was selected in this paper as the research object. Indoor temperature and relative humidity were monitored in field testing during the winter heating period. 4363 sets of effective data were collected in the experimental research. PMV-PDD was calculated to analyse its indoor thermal comfort by a program. The results show that the indoor thermal comfort of the room without a heat source was always not satisfied. Furthermore, the average indoor PMV of the room with coal-fired heating was -1.6 and that with solar heating was -0.5. At the same time, the room with solar energy heating can control the fluctuation margin of indoor temperature within a certain range, especially to the temperature fluctuations during the working time. Therefore, the technology of solar heating was certified as a suitable method to maintain indoor comfort in Xinjiang.
