摘　　要： 探讨了室外空气温度对采暖室内平均辐射温度和热舒适的影响,利用室内热舒适环境评价指标(PMV),分析计算了相同热舒适条件下,由于辐射热损失的不同导致的舒适性室内空气温度的差异.结果表明,达到和北京地区室内空气温度18.0℃时相同的热舒适度,广州地区的室内空气温度为17.2℃.因此,广州地区采暖室内计算温度可以比北京降低约0.8℃. The effects of outdoor air temperature on mean radiation temperature and thermal comfort of indoor heating were discussed.Using the indoor thermal comfort evaluation index PMV,in the same thermal comfort condition,the difference of the indoor air temperature caused by the difference of the radiation heat loss was analyzed.It is shown that to reach the same thermal comfort of Beijing whose indoor air temperature is 18.0 ℃,the indoor air temperature in Guangzhou is 17.2 ℃.Therefore,the calculation temperature of indoor heating in Guangzhou can be lower by about 0.8 ℃ than that in Beijing.
