Solar heat storage greenhouse structure

What is a steel frame solar greenhouse?

With the development of the theory of active heat storage and release, a whole steel frame solar greenhouse has been proposed in recent years 16. This greenhouse structure is composed of a south roof, a north roof and columns. In this type of greenhouse, walls are replaced by columns.

Do solar greenhouses have a thermal performance?

In recent years, many researchers have done relevant studies on the thermal environment inside the solar greenhouse. They have considered different influencing factors to explore the thermal performance of solar greenhouse [6 – 11]. The most important reason for the drop in indoor air temperature is internal heat loss.

What is a solar greenhouse?

Solar greenhouses account for 30.5% of China's horticultural facilities 12. When the greenhouse is designed in accordance with the code, the wind load is applied on the greenhouse structure as a static load. However, the greenhouse bears different amplitudes of dynamic wind loads.

How to design a solar greenhouse?

It is necessary to consider the dynamic characteristics of wind loads in the design of solar greenhouses. A wind-induced vibration coefficient is obtained, which can be used to convert the dynamic load into the equivalent static load and improve its design efficiency.

What are Chinese solar greenhouses used for?

Chinese solar greenhouses exhibit good thermal insulation and heat storage performance. These structures are widely used in agricultural production in northern China. Compared with traditional building structures, greenhouse structures are light and sensitive to wind and snow loads 1.

What is solar greenhouse external insulation?

Solar greenhouse external insulation is divided into two parts: soft insulation and hard insulation. Soft insulation is to cover the outer surface of the south roof of the solar greenhouse with thermal insulation layer at night, by covering the outer surface of the film with thermal insulation quilt.
