How to improve the thermal environment of Chinese solar greenhouses?

This paper summarizes the renewable and sustainable strategies for improving the thermal environment of Chinese solar greenhouses (CSG) from structural forms, north wall materials and equipment for thermal storage. CSG structure forms include sunken, variable south roof and air channel heat exchange.

What is the thermal environment fluctuation model of Chinese solar greenhouse?

The method used dimensional analysis method to comprehensively analyze the related physical quantities of greenhouse thermal environment, explored the temperature fluctuation interaction among indoor air, energy storage wall and outdoor air, and constructed the thermal environment fluctuation model of Chinese solar greenhouse.

What is a Chinese solar greenhouse?

Chinese solar greenhouses (CSG) play an important role in the development of horticultural facilities in China. They are widely used to grow vegetables during winter without any auxiliary heating, especially when the monthly daily average air temperature in the coldest three months of the year was below −10 °C , .

Which type of thermal storage is better in Chinese solar greenhouses?

Combined two or more ways of heat storage forms, the thermal storage ability in CSG will be better. Chinese solar greenhouses (CSGs) play an important role in horticultural development, providing high-efficiency thermal storage performance compared to the other greenhouse styles.

What are the environmental characteristics of different Chinese solar greenhouse types?

The environment characteristics of different Chinese solar greenhouse types. When the depth of the CSG is 0 ∼ 1.0 m, the deeper of CSG, the more increase of air temperature, and the better of insulation.

Can a Chinese solar greenhouse maximize solar energy utilization?

Given the aging of greenhouse facility, there is a need for investigating the transformation of existing greenhouses to maximize solar energy utilization. In this study, Chinese solar greenhouse (CSG) in the Beijing area served as an optimized prototype. A mathematical model was established to determine the range of CSG vertex positions.
