冀东地区典型高效节能日光温室结构对比及改进建议

Comparison and Suggestions for Typical Efficient Energy Saving Solar Greenhouse Structure in Jidong Area

在简要介绍5种温室构型参数的基础上,对冀东地区5种典型结构高效节能日光温室的后屋面、后墙结构、跨度、脊高和低温期温度进行详细对比,讨论5种温室结构的合理性,并提出增加后墙和后屋面的保温性、增加前屋面的保温性、挖设防寒沟、减少出入口热度的散失、安装临时加温设备等改进建议。

On the basis of introducing the parameters of five kinds of greenhouse structures briefly,the rationality of these structures were discussed in this paper by making a detailed comparison of five kinds of typical structures of energy efficient solar greenhouse in roof after,back wall structure,span,ridge height,low temperature in east Hebei area.Some suggestions for improvements were proposed such as improving the thermal insulation properties of the back wall,the rear and front of the roof,setting cold ditch digging,reducing temperature dissipation entrance,installing temporary heating equipment and so on.
