我国寒冷地区村镇温室建筑适用供暖热负荷分析

我国北方地区冬季种植温室供暖是影响蔬果、花卉作物种植实现经济性和高效性的关键。寒冷地区乡村温室建筑的供暖系统设计、运行普遍缺乏量化指导,供暖负荷的设计仍缺乏合理性和行业适宜性、地域适用性。本文以寒冷地区青州地区为例,系统分析典型作物培育温室环境设计需求,通过对温室建筑的围护结构热工性能的分析,提出寒冷地区温室建筑供暖热负荷、热需求参数建议,为确定寒冷地区温室建筑供暖合理设计和运行参数提供参考。

Heating Load for Village Greenhouse Buildings in Cold Regions of North China

The heating system for the greenhouse buildings is the key to achieve economic and efficient planting of vegetables,fruits and flowers in North China in winter.However,the design and operation of the heating system for village greenhouse buildings in cold regions were lack of quantitative guidance.The heating load should quantify the importance influences on the reasonability,industrial suitability and reginal applicability for the village greenhouse buildings.The key design parameters for typical plant breeding greenhouse environment were studied in the paper.Furthermore,the suggestion of greenhouse building heating load and heating requirement parameters were derived with the analysis on building envelope thermal performance.It provides reference for reasonable heating system design and operation of greenhouse buildings in cold regions of north China.
