哈尔滨工业大学工学硕士学位论文 哈尔滨工业大学工学硕士学位论文 II II Abstract With the development of technology and the improvement of living quality, the requirements of indoor thermal comfort have become more and more strict. The favorable indoor environment not only makes people pleased, but also helps to improve wok efficiency. Therefore, it is essential to study the basic law of thermal comfort and creat a healthy and comfortable indoor environment. First, the research method of field study was introduced in the thesis. Considering the error and cost, the mathematical model of reckoning the mimimum sample capacity has been established, with the object function of indoor temperature, relative humidity and air velocity, respectively. Moreover, in consideration of gender, age, community greening, education background, floor area and building age, the analysis of different classifications has been done. The research method has been determined. The subjective questionnaire includes thermal, humidity, air velocity sensations and satisfaction vote, et al. The objective questionnaire includes mainly the characterization of buildings and the measurement of indoor/outdoor air temperature, humidity, air velocity, et al. The research method of thermal comfort field study and data processing methods have been introduced Second, a field study of thermal comfort for Harbin residential buildings with natural ventilation in summer has been done. When we measured the indoor environment variables, the residents’ thermal, humidity and air velocity sensations and satisfaction vote, et al were investigated. The neutrality, preference temperature and acceptability were calculated. The adaptive model of Harbin occupants in summer was presented, which can give support to the workout of the thermal comfort standard. Third, a field study of thermal comfort for Harbin residential buildings before and during heating period was carried out. A comparative analysis of thermal comfort surveys in the two periods is given, e
