医院冬季空调工况热湿舒适需求分析

Questionnaires on the thermal and humid sensation of patients and health people have been done to study on the comfort requirement in Chongqing hospital environment in winter. The subjects in wards votes for their thermal sensation, humidity perception and the total comfort feelings. Air temperature and relative humidity were measured simultaneously in indoor environments. The indoor parameters were divided in Bin method. The linear regression applied to analyze the relations of temperature and mean thermal sensation vote, relative humidity and mean humidity perception. The patients' neutral temperature is 20.4℃, the proper relative humidity is 57%. The health's neutral temperature is 20.4℃ and have higher requirement for humidity. Analysis shows that the patients are more sensitive for the changes of temperature and humidity than healthy people. The thermal and humid comfort ranges are 20-23℃ in temperature and 40%~60% in relative humidity. and it provides guide for design and control of air conditioning system.
