Research on Thermal Comfort for Teachers’ Residential Buildings in Cold Region

Abstract

Abstract This paper mainly discusses the field test of the thermal and humid environment in closed bedrooms in a university teachers’ residential building in Shenyang Province during heating period in winter. The research in this study focuses on three aspects: indoor temperature and humidity changes at nights, the effects of indoor humidity at different humidification locations, and indoor thermal comfort. Results showed that the average indoor temperature at night is 22.2 °C and the relative humidity is 47.56 % also that the three methods of room humidification came up with a conclusion that clarified the role of the effects of humidification, based on contrast and analysis. The third method evaluated thermal comfort of the room using PMV and PPD, which gave the conclusion that the study room was the most comfortable one. Furthermore, this paper analyzes how to improve the indoor thermal comfort. KeywordsTemperatureHumidityPMV–PPDThermal comfort
