摘要
在以往研究基础上,采用实验分析的方法,对所研制复合相变墙体材料的蓄放热特性进行了研究;并将此种材料应用于温室大棚北墙内表面,搭建了普通温室大棚和相变温室大棚的缩尺寸实验台,进行了对比实验。实验结果表明,与普通温室大棚比较,选择相变温度适宜的复合相变墙体材料应用于温室大棚北墙内表面,棚内空气温度及墙体内表面温度可明显提高,其耗电节能率η达到了8%。
The composite phase change material （PCM） developed by our research group was analyzed by the method of experimental tests based on our previous studies. Applying the composite PCM to the inner surface of the north wall in the greenhouse, building the ordinary greenhouse and the PCM greenhouse of small size, the comparative experiment was conducted on. The result indicated that choosing appropriate PCM to the inner surface of the north wall in the greenhouse can increase the indoor air temperature and the inner surface temperature of walls dramatically as well as reduce the power consumption significantly, and make the power saving rate r7 reach 8 % as a result.
