摘　　要：为研究严寒地区火炕采暖不均匀环境的热舒适温度及其影响因素,对火炕农宅冬季的室内热环境进行了现场测试,建立了热舒适评价模型,并对热环境评价方法进行了分析.同时,利用CFD仿真模拟的方法对室内热舒适性的影响因素进行了分析.测试结果表明,火炕农宅冬季的室内热舒适温度为17.7℃,90%可接受的操作温度的范围为14.7~20.8℃.模拟结果表明,在保证基本供暖室温的前提下,较低的火炕表面温度、较高的辅助热源温度以及保温性能较好的围护结构,有助于减小室内温度不均匀性,增加居民热舒适感.火炕营造的微气候环境可以满足农宅居民的热舒适要求.In order to study the thermal comfort temperature of the Kang heating asymmetrical environment and its influencing factors,the indoor thermal environment of the rural houses with heated Kang was studied through a field test in winter.The thermal comfort evaluation model was established and the evaluation method was analyzed.Meanwhile,the influencing factors for indoor thermal comfort was analyzed by CFD simulation.The test results show that the indoor thermal comfort temperature is 17.7 ℃ and 90% of the acceptable operating temperature range is 14.7〜20.8 ℃.The simulation results show that,under the premise of ensuring the basic heating temperature,the lower surface temperature of the Kang,the higher temperature of the auxiliary heat source and the better thermal insulation of the envelope are conducive to reduce the indoor temperature nonuniformity and improve the thermal comfort of the residents.Kang makes the microclimate environment meet human thermal comfort requirements.
