RELATIONSHIP BETWEEN INDOOR AIR CONDITIONING THERMAL ENVIRONMENT AND HUMAN UNCOMFORTABLE SYMPTOMS IN SUMMER

摘要

Purpose: To investigate the relationship between human uncomfortable feeling symptoms and indoor air conditioning thermal environment. Method: The population epidemic investigation method was used for this study. Results: Among the 12 categories of human uncomfortable feeling symptoms due to the use of air conditioning in summer, incidence and happening odds were higher than the control population. Incidences of neurological and psychological uncomfortable feelings were rather obvious. There were other factors which have significant difference in uncomfortable feelings, including stuffy indoor air (12 types of uncomfortable feelings), working in front of video display terminal (VDT) and feeling low temperature in office, and age (10 types respectively), weary of job and education (9 types respectively), tensions of job and house space per person (8 types respectively).Working age had the least effect (2 types). Multi-factor logistic regression analysis showed that the usage of air conditioning both in home and office was the strongest factor related to uncomfortable feelings in summer season,followed by feeling low temperature in office and stuffy indoor air, college education or higher, tensions of job and weary of job. With age it was found that there was a factor that had negatively correlated with 3 types of uncomfortable feelings and positively related to another 3 types of uncomfortable feelings as well. Among all these factors, there were no obvious correlations of stuffy indoor air, tensions of job and weary of job with the usage of air conditioner. All of these three factors seem to be individual factors each other.
