研制背景温室覆盖层的传热量通常占温室总热量损失的75%以上,因此,采用保温性良好的保温覆盖材料来提高温室覆盖层的保温性能,无论对于加温温室、还是不加温的温室或大棚,都是实现其温度环境节能调控的重要途径。目前,中国市场上由不同厂家生产的温室覆盖材料种类繁多,新的产品还在不断开发,对其保温性能的测定、评价等工
Background of research The heat transfer of greenhouse cover usually accounts for more than 75% of the total greenhouse heat loss, therefore, the use of insulation with good insulation material to improve the insulation properties of greenhouse cover, both for greenhouses, or non-warmed greenhouses Or greenhouse, are important ways to achieve its temperature and environment energy regulation. At present, there are various kinds of greenhouse coverings produced by different manufacturers in the Chinese market. The new products are still being developed continuously. The determination and evaluation of thermal insulation properties
