Abstract:
The greenhouses with single layer film red brick，double layer film quilt and double layer film composite wall were used as the experimental greenhouses,comparative analysis of internal environment determination was used,the effects of different types of solar greenhouses on their internal environment were studied,in order to provide reference for using of solar greenhouse.The results showed that the insulation performance of single film greenhouse was inferior to that of double film greenhouse,but the thermal storage capacity of single film red brick greenhouse was stronger than that of double film quilt greenhouse,composite wall insulation performance was stronger than quilt wall and red brick wall.In winter，the minimum temperature of the No.4 double film greenhouse was 12.85 ℃ higher than that of the No.27 single film greenhouse (CK),the cooling rate was 0.47 ℃?h-1 higher than that of the single film greenhouse,the relative humidity of No.4 and No.2 double film composite walls was less than No.27 single film red brick greenhouse (CK),the relative humidity of No.9 double film quilt greenhouse was higher than that of No.27 single film red brick greenhouse (CK),light transmittance of the double film greenhouse was higher than that of single film greenhouse.To sum up,the front roof was covered with double film and the rear wall was made of a composite material can improve the greenhouse insulation performance.
