Product Description

Multi-Span Plastic Film Greenhouse

1.fundamental principles
Characteristic of the sunlight greenhouse is use to accumulate the back wall heat during the day, night to release temperature, but the way of traditional passive heat storage and heat energy accumulation and release process is slow, releasing heat accumulation is limited, uncontrolled heat release process, winter night often cause low temperature and frost damage phenomenon, affecting crop yield and quality. Over the years, solar greenhouse users, in order to improve the indoor temperature, often solve the problem of low temperature by increasing the wall thickness, even reaching 6-8m, which not only wastes land resources, but also has no significant effect.
To solve this problem, the research team of facility Plant Environmental Engineering of Institute of Environment and Sustainable Development in Agriculture, Chinese Academy of Agricultural Sciences proposed the idea of active heat storage and release in solar greenhouse for the first time, and achieved a breakthrough in greenhouse energy storage technology. Use of circulating fluid continuously during the day will arrive at the solar radiation absorption and accumulation of the wall surface, night heat through a fluid circulation again, change passive to active, the accumulation of heat release of doubling efficiency increases, significantly improved the night temperature in winter, the sunlight greenhouse, but also can effectively reduce the north wall thickness achieve greenhouse structure light is simplified.
The latest sixth generation active heat storage and release system is composed of aluminum alloy fin set heat release plate, circulation pipeline, heat storage pool, etc. The heat transfer plate is made of aluminum alloy, with matte black plastic spray surface, 1 m wide and 1.8 m high. The whole system adopts closed cycle method, and the heat transfer water flow is uniform. The average heat collection power of active heat storage and release system is 105-183 W/m2, and the heat collection per unit area is 2.6-4.6 MJ/m2 respectively (0.35-1.2 MJ/m2 for general brick greenhouse). Compared with electric heating, the average energy saving rate is more than 63%, and the night temperature of greenhouse can be increased by 3 to 5ºC.

2.socioeconomic performance
Based on the theory and method of active heat storage and release, the comprehensive supporting technology of energy-saving production of solar greenhouse provides important technical support for the safe production of solar greenhouse crops in winter, and greatly improves the technical level and production performance of solar greenhouse in China.
- active heat storage technology to improve the sunlight greenhouse greenhouse solar heat utilization efficiency as the goal, through the adoption of active heat storage method, winter sunlight greenhouse can accumulate more calories per 147 billion kilojoules, equivalent to 5.1 tons of standard coal, in accordance with the current national heating greenhouse area estimation, install active regenerative heating system can save coal of 3.4 million tons;
-- The use of active heat storage and release system can increase the minimum temperature of solar greenhouse by 3-5ºC, and then increase the output of vegetable facilities by more than 10%, and reduce and eliminate the incidence of chilling injury and freezing injury;
-- The application of active heat storage and release technology has expanded the application range of solar greenhouse. Conventional solar greenhouse can achieve no heating production within 42O north latitude, and the application of this technology can expand the range of at least 2-3O latitude;
-- The use of active heat storage and release technology can further simplify the greenhouse structure, improve the land utilization rate by 30%, reduce the amount of soil used for greenhouse construction by 840 million cubic meters, and save 1.19 million mu of land resources;
-- The active heat storage and release technology improves the control level of the temperature environment in the solar greenhouse, and can release heat according to the temperature situation in the greenhouse, which significantly improves the low temperature condition of the solar greenhouse in the early morning;
-- The price of the developed active heat storage and release system is only 1/10 of that of the domestic solar collector, which significantly reduces the investment cost.
