在寒冷的北方农村地区,火炕作为主要的采暖设施,其局部温度和热舒适性就显得尤为重要,但是传统的火炕存在着燃烧效率低、燃料消耗大、热舒适性低以及燃烧污染大等问题,已不能满足人们对室内热环境的需求。本文针对以上传统火炕存在优势和不足之处进行了探讨,并提出了一种新型的太阳能相变蓄热火炕,将相变材料的蓄热性和毛细管网型太阳能采暖两种技术同时运用到火炕采暖中,可以有效改善改善室内热环境、提高能源利用率、满足农村居民对热舒适性的要求,为农村火炕节能改造提供了一种有效的途径。
In the cold northern rural areas, as the main heating system, the kong is particularly important for its local temperature and thermal comfort, but the traditional kang has the problems of low combustion efficiency, high fuel consumption, low thermal comfort and high combustion pollution , Can no longer meet the people’s indoor thermal environment needs. In this paper, the advantages and disadvantages of the above traditional kang are discussed, and a new type of solar phase change thermal storage kang is proposed. Both the heat storage of phase change material and the capillary net solar heating are applied to the kang Heating, can effectively improve and improve the indoor thermal environment, improve energy efficiency, to meet the requirements of rural residents on thermal comfort, energy-saving renovation of rural kang provided an effective way.
