东北型日光温室太阳能辅助加温系统试验研究

Experiment Analysis of Solar Energy Assistant Heating System for Energy Saving Greenhouse of Northeast China Area

针对利用传统能源为温室地温加热耗能量大、将造成环境污染等现状,对太阳能辅助加热系统进行试验和理论探讨,通过利用太阳能集热器加热水并在地下散热水管中循环散热直接对温室内土壤进行加热,从而作为一种辅助加温措施以达到降低农业耗能量的目的。结果表明,当散热管埋深400 mm时地温最高,较其他散热管埋深及地下埋设有机酿热物更利于植物根系生长,且地温值变化稳定,效果更佳。

Aiming at the defect of large energy consumption and pollution environment led by using traditional energy to heat the soil of greenhouse, the experiment and theory of solar energy assistant heating system is discussed. Hot water of the solar energy assistant heating system and heat dissipation by underground recycle water pipe is used to heat the soil of greenhouse directly. It reduces the agriculture energy consumption by assist heating measure. The result shows that the soil temperature is maximal and more helpful for the growth of plant root than other depth and underground organic heat substance when the radiator pipe is buried in the depth of 400mm. At the same time, subsurface temperature change is stable and the effect is good.
