Characteristics of Residential Thermal Comfort and Energy Consumption in Winter in Hangzhou Based on Personal Comfort Systems
In order to reveal the thermal comfort characteristics and heating energy consumption demand of residents in winter under the effect of personal comfort systems(PCS),this paper takes Hangzhou as the object.By means of questionnaire survey and on-site measurement,the thermal comfort characteristics under various typical thermal environment regulation methods,such as opening windows,shading,using air conditioning and PCS,and indoor hourly temperature and energy consumption are simulated.The results show that the neutral temperatures of"no equipment + sitting","air conditioning + sittin","PCS+ sitting","no equipment + housework","air conditioning + housework"and"PCS+ housework"in winter are 17.3,18.8,16.4,15.7,15.7,13.9℃respectively.A comfortable temperature range respectively is 14.3 to 20.3℃,17.1 to 20.5℃,14.4 to 18.4℃,13.7 to 17.8℃,13.3 to 18.1℃,11.0 to 16.9℃.The indoor thermal comfort level in winter is greatly affected by behavioral patterns.The proportion of comfortable time in the living room is 43.74%～80.21%,and the proportion of comfortable time in the bedroom is more than 70%.When air conditioning and PCS are used for heating,the energy intensity of a typical building is 1.28kWh·m-2 in early and late winter and 13.06kWh·m-2 in severe winter.
