小型木结构建筑太阳能相变蓄热装置性能实验研究

Experimental study on performance of solar energy phase change heat storage device for small wooden structure buildings

以太阳能较为丰富地区的小型木结构建筑为研究对象,结合其处于极端气候下的最不利工况,设计了一种可充分利用可再生能源、占地面积小、储热密度大、蓄放热性能良好的多功能相变蓄热换热装置,并搭建了实验台对影响相变蓄热装置性能的因素进行探究。结果表明,该装置可综合建筑供暖与生活热水的负荷性能特征需求,兼顾在极端气候条件和非极端气候条件下的功能发挥,能有效协调小型木结构太阳能建筑能源供需矛盾。

Taking the small wooden structure buildings in the areas rich in solar energy as the research object,combined with the most unfavorable working conditions in an extreme climate,this paper designs a multi-functional phase change heat storage device that can make full use of renewable energy,occupies a small area,and has high heat storage density and good heat storage and release performance.A test bench is set up to study the factors affecting the performance of this device.The results show that the device can meet the load characteristics of building heating and domestic hot water requirements,meet the functions of extreme climate conditions and conventional climate conditions,and effectively coordinate the energy supply and demand contradiction of small wooden structure solar energy buildings.
