夏季自然通风住宅老年人适应性热舒适评价研究
Field study on elderly people’s adaptive thermal comfort evaluation in naturally ventilated residential buildings in summer
摘要：
为探究自然通风住宅中老年人适应性热舒适的特殊性，在重庆市对6家养老机构和14个居民小区进行了现场研究。结果显示，在夏季热环境中，老年人的热感觉投票值偏低，不满意率也较低，可接受上限温度值偏高。采用预计适应性平均热感觉指数APMV模型预测老年人的热舒适投票值，得到老年人的自适应系数λ=0.55。建议老年公寓采用Ⅰ级指标（0<APMV<0.5）进行热舒适评价，得到对应的老年人可接受温度范围为22.70～27.78 ℃。
Abstract：
To research the elderly people’s special characters of adaptive thermal comfort in naturally ventilated residential buildings, performs a field study in six elderly care centers and fourteen residential quarters in Chongqing. The results show that in the thermal environment in summer, both the thermal sensation vote and the dissatisfied ratio of the elderly people are relatively lower, while the upper limit of acceptable air temperature range is higher. Adopts the adaptive predicted mean vote (APMV) model to predict the thermal comfort vote and obtains that the suitable value of adaptive coefficient λ for the elderly people is 0.55 in summer. Recommends that the index level I (0<APMV<0.5) should be adopted to evaluate the thermal comfort in apartments for the elderly, and obtains that the acceptable temperature range for the elderly is 22.70 to 27.78 ℃.
