在分析国内外自然通风热舒适研究的基础上,结合重庆地区潮湿的气候特点,对现有自然通风热舒适评价模型进行了湿度修正。采用电子温湿度记录仪对重庆地区村镇典型住宅的室内外热湿参数进行了全年监测,并利用该模型对村镇住宅的室内热环境进行了评价。分析表明,村镇住宅室内和室外相对湿度高于70%的时间分别占全年总时间的95.4%和87.2%,室内温度高于28℃且相对湿度高于70%的时间达1 196h;全年舒适时间为3 838h,占全年总时间的43.8%;现有评价模型与修正模型的舒适时间相差405h,其中空调季相差342h,且温度越高,相对湿度对热舒适的影响越大,说明在温度较高时应考虑相对湿度对热舒适的影响,但修正模型的可靠性还需进一步验证。
Based on the analysis of natural ventilation and thermal comfort at home and abroad, combined with the humid climatic characteristics in Chongqing, the existing natural ventilation and thermal comfort evaluation model was modified. The indoor and outdoor heat and humidity parameters of the typical residential buildings in villages and towns in Chongqing were monitored by electronic temperature and humidity recorder. The indoor thermal environment of the residential houses in villages and towns was evaluated by the model. The analysis shows that the indoor and outdoor relative humidity of indoor and outdoor residential buildings occupy more than 70% of the total time accounted for 95.4% and 87.2%, indoor temperature above 28 ℃ and relative humidity above 70% of the time up to 196h; The comfortable time is 3 838h, accounting for 43.8% of the total time of the year. The comfortable time of the existing evaluation model is different from that of the revised model by 405h, the difference of air-conditioning season is 342h, and the higher the temperature, the greater the influence of relative humidity on thermal comfort When the temperature is high, the influence of relative humidity on thermal comfort should be considered, but the reliability of the modified model needs to be further verified.
