| Hot summer and cold winter region has a vast territory and a large population.The climate in this area is hot and humid in summer and rainy and cold in winter.The indoor thermal environment is very bad for there is no central heating in winter.The adaptive thermal sensation and regulation behavior of local residents have obvious characteristics of their own.However,due to its complicated regulation behavior and many influencing factors,the influence mechanism among adaptive regulation behavior,thermal comfort and energy consumption needs to be studied urgently.This paper chooses Hangzhou as a typical city in this area,and takes the residential buildings in the main urban area as the main research object,adopts the method of large-scale questionnaire survey and typical household measurement to analyze the characteristics of various adaptive adjustment behaviors of Hangzhou households and the characteristics of indoor thermal environment in the whole year under the action of adjustment behavior,and reveals the regulation effect of behavior on indoor thermal environment.Based on large-scale questionnaire and measured data,the adaptive coefficient ? recommended by GB/T 50785-2012 is revised.It is proved that the revised ? can more accurately evaluate the adaptive thermal sensation of local residents than the original value.Based on the modified APMV,the effect of summer ventilation on thermal sensation was quantitatively analyzed.According to the indoor temperature simulation curve of typical households under the influence of typical meteorological year climate,the service life of air conditioning in winter and summer is obtained.Through the simulation of typical buildings,the appropriate control strategies of air conditioning and window opening are recommended.The conclusions can provide theoretical support for energy-saving oriented indoor thermal environment improvement research in this area. |
