Product Description Double arch double film solar greenhouse is short for double arch double film energy-saving solar greenhouse,more light, more volume, better climate control. 1. Double frame. The greenhouse skeleton is divided into two layers inside and outside, the outer skeleton is covered with a transparent shed film, the inner skeleton is covered with a waterproof insulation shed film and thermal insulation curtain, and the rolling machine and rolling film machine are installed between the double skeleton to facilitate thermal insulation and the lighting is good, which is conducive to winter heating. 2. Multiple layers of insulation. The greenhouse insulation layer is increased from 2 to 4 layers of the ordinary greenhouse, and the greenhouse curtain and the inner layer film cover the inner layer trellis at night, which plays the role of heat preservation and cold protection. 3. Ventilate front and rear. The greenhouse vents are arranged in front and back, the front vents are arranged in the front end of the outer skeleton, and the rear vents are arranged in the back slope of the outer skeleton, which is convenient for ventilation and cooling. 4. Mechanical and manual curtain rolling. The greenhouse straw curtain is rolled with a rolling machine, and the inner curtain film is rolled with a rolling machine. The rolling machine and the rolling machine adopt a wireless remote control system to control the rolling and releasing. At the same time, the rolling machine and the rolling film machine also have a manual rolling and releasing device. Our Advantages 1. The extreme minimum air temperature in the double-arch double-film energy-saving II greenhouse is 3-5 ºC higher than that of the ordinary second-generation energy-saving greenhouse, and the indoor temperature can reach 8ºC under normal circumstances. 2. When the snow falls in winter, the snow on the outer layer film of the double-arch double-film energy-saving II greenhouse melts at any time during the snow process, and automatically slips to the front or back wall of the greenhouse, eliminating the manual snow clearing link, and there is no snow collapse of the greenhouse phenomenon. 3. Without increasing the coverage area of the straw curtain and reducing the thermal insulation performance of the straw curtain, the incidence Angle of light entering the greenhouse is increased, and the light transmittance of the greenhouse is correspondingly improved, which solves the contradiction between light transmittance and thermal insulation that exists in the solar greenhouse for a long time. 4. The two tuyere before and after the greenhouse are all set on the slope of the greenhouse with a slope of more than 60 degrees, and the rain can go down the slope, and there is no water accumulation in the rear tuyere. 5. The greenhouse curtain is protected by the outer canopy film, no moisture throughout the year, no disassembly, the use period is extended from 3 years of ordinary greenhouse to more than 6 years, reducing the cost of the curtain by more than 50%, and saving 30-50 labor per year. 6. The pressure generated by rain, snow and wind on the greenhouse and the pressure generated by the curtain on the greenhouse are shared on the internal and external two layers of trellis, which greatly improves the snow resistance of the solar greenhouse. Equipments of greenhouse More systems can be customized 1) Internal sunshade: Install a sunshade net inside the greenhouse. Rack and pinion drive, smooth running, high control accuracy, long service life, easy maintenance. 2) External sunshade: Install a sunshade net on the top of the greenhouse to prevent indoor crops from being burned by strong light in summer, reducing the indoor temperature
