摘要
本实验考虑到建筑本身的节能,采用了保温、隔热性能良好的高性能围护结构搭建了主动式太阳房,以太阳能热水为热源,实验房的2个房间分别采用相变蓄热地板供暖系统与干式地埋管地板供暖系统,实测了2种地板供暖系统的蓄放热性能以及其对房间热性能的影响。运用相变蓄热地板供暖的房间,提高了室内最低温度的同时,温度波动减小了3.5℃,铺设的相变材料利用率较高。可根据需要进行自动调节的主动式太阳房供暖系统与相变蓄能地板的结合应用达到了节能降耗和提高房间舒适度的效果。
Taking into account the building itself energy saving,high-performance building envelop which insulation properties is comparatively better is used to build an active solar house.Using solar hot water as a heat source,phase change energy storage floor heating system and dry-pipe floor heating system are arranged respectively in experimental room.We test the characteristics of storing and releasing thermal energy of two floor heating system and its influence on thermal comfort of the room.Indoor temperature fluctuation which use phase change energy storage floor heating system is reduced by 3.5 ℃ as well as the increase of indoor minimum temperature.Utilization of arranged PCM is relatively high.Combination of active solar house heating system which can be automatically adjusted as required and phase change energy storage floor achieve the effect of energy saving and improving room comfort.
