- 为研究日光温室土质梯形截面墙体热量环境，测定了温室墙体内表面上、中、下3点太阳辐射照度、热通量及3点距墙内表面0.05 m和0.30 m 处2个层次测点的温度。结果表明：墙体表面上、中、下3点太阳辐射和墙内温度由上向下均逐步升高，3点日均太阳辐射总量分别为2.21、2.30、3.08 MJ?m-2；0.05 m处上、中、下3点平均温度分别为2.37、13.83、14.13 ℃，0.30 m处分别为11.13、12.62、13.34 ℃；3点吸热量也是由上向下依次升高，试验期间3点分别累计吸热85.60、85.80、92.89 MJ?m-2；墙体上部平均放热量最小，下部次之，中部最大，上、中、下3点放热量分别为76.47、96.88、93.70 MJ?m-2；墙体吸热和太阳辐射直接相关，也和墙体放热显著相关，墙体放热又与墙内温度相关，因此太阳辐射直接影响到墙体热量环境。试验证实日光温室土质梯形截面墙体不同高度太阳辐射与热环境存在差异。
- Abstract:
- Solar greenhouse with trapezoidal soil wall is widely used due to its good heat retaining property and cost efficiency.In this study,solar irradiance,heat flux and the temperature at 0.05 m and 0.30 m from the inner surface of the wall at the upper,middle and lower points were determined to study thermal condition of the trapezoidal soil wall in solar greenhouse.The results showed that solar radiation and temperature at inner wall.Both solar irradiance and temperature of inner solar greenhouse at the upper,middle and lower points increased from the upper to the lower point.The total solar irradiance at the three points were 2.21,2.30,3.08 MJ?m-2 individually.The average temperature at 0.05 m at the three points were 2.37,13.83,14.13 ℃individually,while average temperature at 0.30 m were 11.13,12.62,13.34 ℃.Heat absorption increased from the upper point to the lower one,and the total heat absorption were 85.60,85.80,92.89 MJ?m-2 at the three points during the testing time.The average heat emission reached the lowest at upper point,and the average heat emission at lower point was higher than at the upper point,and it got the highest at the middle part.Heat emission at the three points were 76.47,96.88,93.70 MJ?m-2 individually.Heat absorption and solar irradiance were correlated with each other.Heat absorption affected heat emission,while heat emission affected by inner wall temperature.Therefore,solar irradiance directly affected the thermal condition of a solar green house.
