摘要
讨论了三面环墙一面透光日光温室的散热问题。计算了采用不同保温材料日光温室夜间的逐时散热量,并进行了经济性和适用性分析。按经济性及适用性考虑,在干旱少雨地区,以密实草苫作为保温材料优于交联聚乙烯和保温棉被。
To the question of sunlight greenhouse, which is surrounded by three walls and a incident surface, calculated the sunlight greenhouse＇s heat emission when the incident surface is covered by different materials during the night. And analyzed its economy and adaptation.Taking economy and adaptation into account, using close grained grass carpet as heat insulating material is superior to using cross linked polyethylene and insulation pads at the rainless area.
