Solar greenhouse construction is an energy-saving solar greenhouse, which is a unique greenhouse type in Shuofang area of my country. It is a greenhouse that is not heated indoors. Even in the severe cold season, it can rely on sunlight to maintain a certain indoor temperature. Therefore, it is also called a greenhouse to meet the needs of vegetable crop growth.
1. Advantages of solar greenhouse construction in terms of lighting
Solar greenhouse construction: On the one hand, solar radiation is an important source of energy to maintain the temperature of the solar greenhouse or to maintain uniform heat; on the other hand, solar radiation is the light source for photosynthesis of crops.
2. Thermal insulation advantages of solar greenhouse construction
The thermal insulation of solar greenhouse construction consists of two parts: thermal insulation enclosure structure and movable thermal insulation quilt. The thermal insulation material on the front slope should be made of flexible material that can be easily folded up after sunrise and put down at sunset.
The research and development of new front roof insulation materials mainly focuses on the requirements of easy mechanized operation, low cost, light weight, aging resistance, waterproof and other indicators.
The construction structure of the solar greenhouse is mainly composed of three parts: the surrounding wall, the rear roof and the front roof, referred to as the “three elements” of the solar greenhouse. The front roof is the entire lighting surface of the greenhouse, and the front roof is only covered with plastic film during daylighting hours. Daylighting, when the outdoor light weakens, cover the plastic film with a movable insulation quilt in time to enhance the insulation of the greenhouse.
