Effects of heat preservation measure on indoor temperature for Chinese solar greenhouse with an attached tunnel
摘要
Abstract
To investigate the effects of the heat preservation measures adopted on the indoor air temperature of Chinese solar greenhouse(CSG)in this study,three testing cases,attaching a tunnel to CSG,covering the attached tunnel with an insulation blanket and strengthening insulation on the CSG wall with its south roof covered with a thermal blanket,were conducted for one testing CSG and one reference CSG.This study focuses on the comparison of morning and night temperatures.The results showed that:Under low outside air temperature,the average air temperature difference between the CSG with an attached tunnel and the reference CSG in the morning and night is generally within 0.5 ℃;When the external temperature is high,it is usually 1.0~4.0 ℃.The results also indicate that the indoor air temperature increment is not obvious for a CSG with a layer of blanket covering the attached tunnel than that in the reference CSG,with the maximum temperature difference of 1.0 ℃presented in the morning and night in January.Compared with a reference CSG with the same attached tunnel,a CSG with strengthening insulation on the wall and thermal blanket has an average maximum difference of 4.2 ℃ in the morning and at night in January with the low external temperature;The average maximum difference is 6.5 ℃in February with high external temperature.The findings in this study provide references for the design,construction,selection of insulation measures and CSG ventilation management.关键词
