The thermal conditions required for comfort in the indoor environment have stimulated much research. Results of this research have both elucidated the physiological mechanisms which determine what conditions are comfortable as well as defining the combinations of physical variables which constitute these. This paper discusses these two aspects of thermal comfort in relation to the home environment  相似文献

Following suggestions of high levels of carbon monoxide (CO) being reached in kitchens the source of this toxic gas was investigated to check this statement. Four gas cookers were tested to determine the concentration of carbon monoxide produced when they were in use. Levels reached were found to be below the Greater London Council guidelines1 for exposure over 1 h; however, if this level was maintained over 3 h it would have exceeded the suggested maximum by 2.7 times exposure level. The paper also summarizes the medical implication of exposure to carbon monoxide.  相似文献
