摘　　要：为实现温室内全天供热、变温管理和节能的目的,结合大型玻璃温室和无土栽培技术要求,确定了总体加温结构设计方案和工作原理,对主要装置集热器进行选型和结构设计;利用Solidworks三维建模对太阳能板的安装和排布进行说明和分析,并结合当地的气象资料对单位面积的集热效率进行经济性分析,考虑太阳能的不稳定因素,分别设计了主加热及辅助加热系统。结果表明,对太阳能集热的设计和科学的安置有效地提高了太阳能的利用率;与传统电加温进行经济性计算,在20年内单位面积可节约能源12 942.46 k W·h,为我国现代化温室加温系统的研究提供了参考。In order to provide heating all day, manage variable temperatures, and save energy in greenhouse, the heating system of greenhouse was designed based on solar energy and cultivation bed. The overall project, operating principles and critical components of energy collection were designed according to the large automatic greenhouses and the technical requirement of soilless cultivation. The setup and assignment of solar panels was described and analyzed by using solidworks modeling operations. The heating efficiency in per unit area was analyzed based on the local meteorological data. Considering the unstable factors of solar energy, the heating system contained main heating and auxiliary system. The reasonable assignment and design of solar collector enhanced the heating efficiency. saved 12 942.46 kW·h in per unit area. It will provide reference Comparing with traditional electric heating, the energy was for heating of modern greenhouse in China.
