China Wholesale Black-White Film Greenhouse Factories - Solar warm greenhouse – Lantian

The solar thermal greenhouse is the most energy-efficient type of greenhouse, so it is also known as the warm shed. It consists of gables and back walls on both sides, that is, three thermal insulation walls and a light-receiving slope. As shown
The light-receiving slope of the solar greenhouse faces within plus or minus 15 degrees in the south direction, and its slope maintains the best angle between 25 and 35 degrees with the sun, so that the sun’s light and heat can be fully and effectively utilized.
The light-transmitting covering material of the light-receiving slope of the solar warm greenhouse can be divided into thin film, double or multi-layer solar panels and glass.
The outside of the light-receiving slope of the solar greenhouse is covered with a thermal insulation blanket that can automatically roll up and down. The thermal insulation blanket is made of sprayed cotton with good thermal insulation, light weight, non-water absorption, softness and good flame retardancy.
The thermal insulation materials for the gable and back walls on both sides of the solar thermal greenhouse can be made of color steel sandwich panels, thermal insulation quilts, double-layer membranes, and brick-concrete materials.
Since the three walls of the solar thermal greenhouse are made of thermal insulation materials with good thermal insulation properties, the light-receiving slope is well received by the sun and is covered with heat preservation. Therefore, the solar greenhouse can both increase temperature and heat insulation. Therefore, in colder areas, the greenhouse does not need to supply heat in winter. It can also grow normally.
The solar greenhouse with color steel sandwich panels as insulation materials on three sides is suitable for areas in the winter from minus 15°C to minus 20°C. In the case of no heating, the indoor temperature is about 10°C above minus to ensure the normal growth of crops. The solar greenhouse with thermal insulation quilt or double-layer film as three-sided thermal insulation material is suitable for areas where the temperature in winter is as low as 0℃ to minus 5℃. The indoor temperature is about 10℃ above minus without heating, which can ensure the normal growth of crops; The solar greenhouse made of three-sided thermal insulation with mixed masonry is suitable for winter when there is no heating in the area of ​​minus 20°C to minus 25°C, and the indoor temperature is about 10°C above minus to ensure the normal growth of crops.
Therefore, this kind of thermal insulation greenhouse is currently very popular in relatively cold regions all over the world.
