Fabricated land-saving energy-saving high-performance solar greenhouse and building process thereof

Abstract

Provided is a fabricated land-saving energy-saving high-performance solar greenhouse and a building process thereof. The building structure that an overall light steel framework and a heat absorption and storage heat preservation multilayer composite encircling body are combined is adopted in the solar greenhouse. The standardized and modularized component assembly process is adopted during building of the solar greenhouse, and all components are connected through fixing parts. According to the greenhouse, the land can be saved by 50%, the room temperature can be improved by 4 DEG C or above, heating is not needed at northern latitude 43 degrees, and high performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of modern agriculture, and relates to a solar greenhouse, in particular to an assembled land-saving, energy-saving, high-performance third-generation solar greenhouse and its construction process. Background technique [0002] One of the directions of modern agriculture is to develop efficient planting represented by greenhouse facilities. In developed countries in Europe and America, represented by the Netherlands, the development of large-scale multi-span modern greenhouses is the main focus. However, due to its large investment and high energy consumption for heating, its development in my country is limited. my country mainly develops China's original solar greenhouses. Due to the small investment in solar greenhouses, no heating or only auxiliary heating, and sunlight as the main heat source, it has adapted to the national conditions and achieved unprecedented development, accounting for more than 80% ...

AI Technical Summary

Problems solved by technology

Among these materials, polystyrene foam board has good thermal insulation performance, but poor heat storage performance, and the room temperature drops rapidly at night.

While other materials have good heat storage properties, but poor thermal insulation properties

Due to the poor comprehensive performance of the wall materials used for thermal insulation and heat storage, the wall can only increase the thickness to improve the thermal insulation effect

But even so, the second-generation solar greenhouse can only make the lowest room temperature reach 8°C without heating, which is still low. In areas north of 43° north latitude, heating is still required at night, and energy saving is not ideal.
