加热温室中供热管道位置的确定
The optimal location of heating tubes in greenhouse
【摘要】 从辐射传热和对流传热两方面,对加热温室中供热管道不同位置的热效进行了定量和定性分析,得出了供热管道的合理位置应该在靠近作物并位于作物高约1/4~1/3处
【Abstract】 The paper analyses the effect of the location of heating tubes in greenhouse from both radiation and convection.An optimal range for the tube location is near the crop and about 1/4~1/3 of the crop from the ground.
