Structure Optimization Of Solar Greenhouse In Jinzhong Area Based On Environment

By the use of the sunlight greenhouse thermal environment simulation prediction software, this paper mainly simulated the internal environment of36type solar greenhouse which have the same azimuth, building materials, indoor plants flourish, ground temperature and humidity levels.The main conclusions in this paper are as follows:(1) By keeping the span and front and back roof angle invariable, the lowest temperature within greenhouse had a linear increase with the increase of the ridge position ratio;(2) By keeping the span and front and back roof angle invariable, the lowest temperature within greenhouse had a linear increase with the increase of depth-span ratio;(3) By keeping the ridge position ratio and front and back roof angle invariable, the lowest temperature within greenhouse increased with the increase of the span;(4) By keeping the span and front and back roof angle invariable, the Land utilization decreased with the increase of the ridge position ratio;(5) By keeping the ridge position ratio and front and back roof angle invariable, the Land utilization increased with the increase of the span;(6) When solar greenhouse azimuth Angle is0°, the lowest temperature is the highest in greenhouse, with the increase of azimuth absolute value, the lowest temperature will be reduced in the greenhouse.(7) Greenhouse with a span of7m, back wall hight of4.06m, ridge hight of4.32m had optimal comprehensive evaluation.
