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.
The greenhouse optimizing strategy combined lighting, heat storage and safety. The average solar radiation and temperature increased by 5.4 MJ m −2 and 3.1 °C. The cost of optimizing Chinese solar greenhouse can be repaid in 1.6 years. The proposed framework can be applied to solar greenhouses at any latitude.
A Chinese passive solar greenhouse is a structure with three walls made of brick or clay and only the southern side consisting of transparent material (usually plastic foil). The southern wall allows sunlight to enter, and during the day, the greenhouse captures heat from the sun in the thermal mass of the walls, which is released at night.
Total light interception and daily effective accumulated temperature of Chinese solar greenhouse with different lighting roof shapes. According to the above obtained results, the five CSGs with the optimum performance have been determined (S09, S109, S110, S120, S121).

Given the aging of greenhouse facility, there is a need for investigating the transformation of existing greenhouses to maximize solar energy utilization.
The performance of a Chinese greenhouse depends on its design, the latitude, and the local climate. A recent study observed three types of greenhouses in Shenyang, which is at 41.8°N and is one of the most northern areas where the Chinese-style greenhouse is built (between latitudes 32°N and 43°N).

Introduction. In most countries, the greenhouse agricultural sector represents the largest consumer of total energy [] inese solar greenhouse (CSG) is an important agricultural facility for the cultivation of vegetables and fruits in cold regions throughout the year [].Moreover, it plays an important role in winter cultivation of agricultural products in northern China.
Chinese solar greenhouse (CSG) is mainly developed to create a suitable indoor environment to meet the temperature, humidity, lighting and other needs of crop''s growth by uses the energy of the sun [1, 2]. The operation principle of a solar greenhouse is mainly based on the utilization of solar energy.
Therefore, a solar greenhouse with an innovatively applied internal insulation system was proposed in this study. To analyze the light performance of the solar greenhouse, a solar...
Therefore, the design of a solar greenhouse must address the lighting of the greenhouse to maximize sunlight penetration into its interior [6]. Winter in China is characterized by a low solar altitude angle of only 21.4° on the winter solstice. Therefore, the design requirement for solar greenhouses is to maximize solar energy utilization in
Chinese-style greenhouses are catching the eye with their unique, energy-efficient designs. LOW TECH MAGAZINE reports that these greenhouses use only solar energy. Even in cold weather, they can keep the …
In China, as an unique type of solar energy collectors, Chinese solar greenhouses (CSGs) are widely promoted in China owing to their energy savings, improved efficiency, reduced energy consumption, and low costs.
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. Then, a 3D dynamic simulation model was developed to optimize greenhouse structure and determine the lighting roof shape that offers better light and temperature ...
Our team keeps bringing forth new ideas, successively developed more than 10 types of greenhouses, such as Venlo type glass greenhouse, Venlo type PC (polycarbonate) sheet greenhouse, multi-span arch-type film greenhouse, single-span arch-type film greenhouse, hydroponics greenhouse, tomato greenhouse, mushroom greenhouse, aluminum alloy …

Chinese-style greenhouses are catching the eye with their unique, energy-efficient designs. LOW TECH MAGAZINE reports that these greenhouses use only solar energy. Even in cold weather, they can keep the inside up to 25°C (45°F) warmer than the outside. No energy-guzzling heaters are needed. What''s a Chinese-style passive Solar Greenhouse?
Numerical simulation is an effective tool for the thermal management of propulsion systems. Moreover, it contributes to the design and performance assessment of solar greenhouses for mushroom ventilation. Because the planning and design of the clustered solar greenhouse are still undiscovered, this study has developed a 3-D mathematical model …
