摘要
设施农业是我国现代化进程中的一个重要内容 ,现代化温室作为设施农业的标志 ,正在受到大力发展和重点研究。为了对温室热水供热系统散热管道的热工性能进行研究和测试。论文主要进行了以下工作 :对温室热水供热系统散热管道的热工性能进行理论分析和计算 ;在密闭小室内 ,对温室散热管道热工性能进行实际测试。通过理论计算与实际测试 ,得出了散热管道传热系数的实验公式 ,并分析了可信性与影响因素。
People now emphasize on the research and development of agricultural greenhouse due to its key position in protected agriculture.The objective of this article is to research and test the thermodynamic function of the heating pipe of water heating system in greenhouses. The content of the article is: to do some theoretical analysis and calculation of the thermodynamic function of the heating pipe of water heating system; to perform some practical tests of the thermodynamic function of the heating pipe from the sealed chamber Lab. Through theoretical analysis and practical test, the formula of the coefficient of heat transfer of the heating pipe was obtained, and the reliability and the influential factors of the formula were analyzed.
