Abstract

Abstract:

【Objective】This project aims to clarify the basis for selecting the heat-retaining quilt material and choosing the heat-retaining quilt of every layer material suitable for the cost performance and safety of the greenhouse.The finding from research has provided a reasonable basis and reference for the design, selection, operation and maintenance of heat-retaining materials for the greenhouse.【Methods】The heat-retaining characteristics of the heat-retaining quilt were indicated by heat transfer coefficient, which was measured by using a static hot box test method. Under the status of one-dimensional stable heat transfer, the air temperature differences on both sides of the cover material specimen and the heat flow rate through the part were measured, and then the heat transfer coefficient and heat transfer resistance of the cover material and other parameters related to heat-retaining performance were calculated by the heat flow rate.【Results】The more heat-retaining material in front of the greenhouse, the more heat transfer resistance, the smaller the heat transfer coefficient, and the better heat-retaining performance. Generally speaking, the heat transfer resistance was between 0.8 to 2.7 (m²·℃)/W. When selecting heat-retaining quilts, the main considerations were heat transfer resistance. The preferred outer material was waterproof material, the intermediate layer material was insulation cotton insulation quilt. Preferred outer material was non-woven fabric, intermediate layer material was pearl cotton, sandwich cotton insulation quilt. When the outer layer of insulation material was non-woven, the intermediate layer material in the quilt was to choose insulation cotton and wool mesh.【Conclusion】The outer layer material is waterproof material, the intermediate material is thermal insulation cotton insulation is suitable for Xinjiang solar greenhouse because of the good cost performance and safety.

摘要：

【目的】分析保温被材料选用依据,确定适合日光温室性价比和安全性的保温被各层材料,为日光温室保温材料的设计、选用和使用维护提供合理依据和参考。【方法】保温被的保温特性以传热系数来表征, 保温被的传热系数用静态热箱测试法测量。在一维稳定传热的状态下,测定覆盖材料试件两侧的空气温度差和通过试件的热流量,再根据热流量求得覆盖材料的传热阻等与保温性能有关的参数。【结果】日光温室前屋面保温被材料层数越多,传热阻越大,传热系数变小,保温性能越好。一般保温被传热阻在0.8~2.7 (m²·℃)/W。选择保温被时,主要考虑传热阻。首选外层材料是防水材料、中间材料为保温棉的保温被。优选外层材料无纺布,中间材料珍珠棉、夹心棉的保温被。保温被外层材料均是无纺布时,保温被中间材料选保温棉和毛网卷。【结论】外层材料是防水材料,中间材料是保温棉的保温被适合新疆日光温室,性价比和安全性都好。
