摘　　要：该文从连栋温室供热系统的节能要求出发,采用理论分析和实验数据数学归纳的方法,重点研究涂镀辐射涂层前后常用的热水供热系统光管散热管道热工性能的变化,结果表明涂镀辐射涂层后光管散热管道的热工性能较涂镀辐射涂层前有明显的提高,为选择连栋温室散热管道提供依据。From the viewpoint of the energy efficiency, this paper focuses on the difference of the thermo-engineering capability between the two pipes-common pipes and pipes coated with radiant dope and the influence on the thermal environment in gutter-connected greenhouse by enhancing radiant heat-transfer capability of heating pipe. This result provides a basis for the design of economic gutter-connected greenhouse.
