| Abstract (English): |
Chinese solar greenhouses (CSGs) are the important agricultural building facility with highly efficient and sustainable utilization of solar energy. In order to improve the thermal insulation performance and reduce the heat loss, different insulation cover measures were applied to Chinese solar greenhouses. In this study, a solar greenhouse with an internal insulation blanket (SG1), a greenhouse with an internal blanket and an internal plastic film (SG2) and a greenhouse with an external blanket, an internal blanket and an internal plastic film (SG3) were chosen as experimental objects to analyze their indoor temperature environment. The results indicated that the differences of solar radiation interior among three greenhouses were similar, which was not the main reason that caused the differences of the temperature environment in the three greenhouses. During the tests, the nighttime average temperature was increased by 2.1-3°C by adding the cover materials, and the duration of nighttime temperature greater than 8°C was increased by 33.5%-38.2%. In addition, the cost is increased by adding the insulation cover materials, but it will be beneficial for greenhouse production to reduce additional energy consumption. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
日光温室是中国重要的农业设施, 它能高效可持续的利用太阳能。为了改善温室保温性能从而减少热损失, 研 究了不同覆盖方式对日光温室温度环境的影响。该研究对单被内保温日光温室（SG1）, 单被双膜内保温日光 温室（SG2）以及双被双膜内保温日光温室（SG3）进行了温度环境测试。研究结果表明：三座温室内太阳辐射 的差异较小, 而它们的温度环境的差异并非由所获得太阳辐射差异所造成。在测试期间, 通过增加保温覆盖物, 可使夜间平均温度增加2.1～3°C, 而且相较于SG1, 夜间温度大于8°C 的持续时长也能够提升33.5%～38.2%。 此外, 尽管增加保温覆盖使得成本上升, 但是对于长期温室生产并减少额外供热是有利的.
