热湿气候区远海岛礁自然通风建筑热舒适实验研究

热湿气候区远海岛礁具有独特的气候特征:高温、高湿、强太阳辐射、日/年温差小、高盐雾、全年海风等。通过主观问卷和客观参数测量相结合的方法,研究了岛礁居民的热中性温度、热偏好温度、热舒适温度范围及岛礁建筑室内环境营造策略。招募了150名岛礁居民作为受试者,通过现场实验,得到570份有效问卷。数据分析表明,岛礁居民的热中性SET为25.4℃,热偏好SET为27℃,热舒适SET范围为20.2~30.5℃。在岛礁高温、高湿环境下,温度是影响受试者热舒适的主要因素,相对湿度并没有显著影响受试者热舒适投票。

Field study on thermal comfort of natural ventilation buildings in offshore islands in hot and humid climate zone

The offshore island in hot and humid climate zone has unique climate characteristics,such as high temperature,high humidity,intensive solar radiation,small day/year temperature difference,high salt fog and annual sea breeze,which is different from the inland climate in China.Studies the thermal neutral temperature,thermal preference temperature,thermal comfort temperature scope and the construction strategy of the indoor environment of island reef buildings by combining subjective questionnaire and objective parameter measurement.Recruits 150 island residents as subjects,and obtains 570 valid questionnaires through field experiments.The results show that the thermal neutral SET is 25.4℃,the thermal preference SET is 27℃,and the thermal comfort SET range is 20.2 to 30.5℃.The results show that temperature is the main factor affecting the thermal comfort of the subjects in the high temperature and high humidity environment of the island.On the contrary,the relative humidity does not significantly affect the thermal comfort vote of the subjects.
