Study on optimization effect of south roof curve of Chinese solar greenhouse
<p><span>To maximize the use of solar energy and increase the utilization area of Chinese solar greenhouse (CSG) land, a solar greenhouse radiation model was established based on previous studies, combining with the law of solar movement, meteorological data, and optical properties of materials. The model is verified by selecting the measured data of typical sunny days. The results show that the optimization of the south roof curve of the greenhouse can not only increase the land-use area in the greenhouse but also increase the solar energy captured by the solar greenhouse. And the CSG in the greenhouse, the land-use area in the greenhouse increased to 42 m<sup>2</sup>, the lighting rate of the south roof, and the lighting rate of the ground increased 15.2% and 0.78% respectively. The amount of interception in the back wall of the greenhouse was reduced by 0.67%, and that in the greenhouse was increased by 2.22%. The optimal structure CSG in Shenyang (span 9 m) is the optimal shoulder height position, obtain the best shoulder height position of the greenhouse, the level of front and bottom Angle is 0.7 m, and the height is 2 m. Combined with the actual greenhouse construction demand, the optimal curve function Y1 and Y2 of the south roof of the greenhouse are calculated. This paper verifies the structural safety of the front roof of the greenhouse after the renovation, and shows that increasing the shoulder height can also increase the structural stability of the greenhouse and strengthen the structural safety of the greenhouse.</span></p>

Effect of external thermal insulation layer on the Chinese solar greenhouse microclimate
<p><span><span>In order to optimize the heat preservation capacity of Chinese solar greenhouse (CSG) and further reduce energy consumption, we clarified the mechanism of the external thermal insulation layer that affecting the microclimate environment of CSG. The most excellent thickness of the external insulation layer of the solar greenhouse envelope structure in high latitude and cold region has been indicated. A three-dimensional mathematical model was developed based on computational fluid dynamics (CFD) and verified using experimental measurement. The temperature variations, heat variations and economic benefit were analyzed. The results indicated that covering the outer surface of the enclosures with a thermal insulation layer could effectively increase the greenhouse temperature by 1.2~4.0°C. SW had the lowest unit cost (USD 282.52/°C), but it limited the increase in greenhouse air temperature. Covering the outer surface of the north wall with insulation layer has better profitability and higher cost performance than that of the side wall and the north roof. During the construction of the greenhouse in high latitude and cold region, CC as the optimal solution could raise the greenhouse air temperature maximally. The optimal thickness of the external insulation layer of each maintenance structure is obtained as follows: north wall 80 mm, side wall 80 mm, north roof 100 mm.</span></span></p>
