复合相变蓄热墙体材料应用于日光温室的效果研究

Experimental Results of the PCM Wallboard Material Applied in the Solar Greenhouse

日光温室墙体作为集蓄热保温隔热于一体的墙体围护结构,对温室热环境的影响至关重要。现将课题组曾研制的复合相变蓄热墙体材料涂抹于日光温室后墙内表面,利用相变材料能够在较小的温度区间下蓄存和释放大量相变潜热的特点,研究日光温室相变蓄热墙体的蓄热能力。结果表明:涂抹相变蓄热材料后,在不用加大砖墙厚度的情况下可获得较大的蓄热能力。

As the main thermal storage and insulation structure,the north wall had important impact on the indoor thermal environment.Using the characteristics of storing and releasing large amounts of latent heat in a small temperature range,the composite phase change material applied in the inner wall surface of greenhouse can get a larger thermal storage capacity than the brick wall.The results showed that the after daub the phase change material,under not increase thickness of brick wall by red brick,availability of large thermal storage capacity.
