Tests the winter indoor thermal environment parameters of two reconstructed nursing homes for the elderly in Taiyuan, and investigates the thermal comfort of the elderly in three reconstructed nursing homes for the elderly by subjective questionnaire. Statistically analyses the data by means of correlation analysis and regression analysis. The results show that the acceptable thermal comfort temperature range of 90% of the elderly in winter is 21.5 to 23.4 ℃, the thermal neutral temperature is 22.4 ℃, and the thermal expectation temperature is 23.8 ℃. There are some problems in the nursing homes in winter, such as dry air, overcooling in the activity rooms, high temperature in some period of time in the living rooms, and so on. In view of the existing problems, puts forward the corresponding improvement measures for the indoor thermal environment.
