Description

Technical Field

[0001] The invention relates to the technical field of greenhouse temperature control and regulation, and in particular to a temperature control and regulation system for an agricultural greenhouse utilizing solar energy. Background Art

[0002] With the development of agricultural modernization, agricultural greenhouses are being used more and more widely. In agricultural greenhouses, temperature control is a very important link, which directly affects the growth and yield of crops. At present, the temperature control of most agricultural greenhouses mainly relies on traditional energy sources, such as coal, oil, etc. These energy sources are not only expensive, but also pollute the environment. In addition, there are some problems in the light regulation of existing agricultural greenhouses, such as uneven light, local light is too strong or too weak, which will affect the photosynthesis and growth and development of crops. Therefore, how to use solar energy to achieve temperature control of agricultural greenhouses, reduce dependence on traditional energy, reduce energy costs, and at the same time improve the utilization efficiency of light to provide a suitable growth environment for crops is an urgent problem to be solved in the current development of agricultural greenhouses.

[0003] Traditional greenhouse designs may not fully consider the uniform distribution of light. Due to factors such as the structure of the greenhouse and the characteristics of the covering material, the sunlight may be too concentrated in some areas of the greenhouse, while it is relatively weak in other areas. This results in large differences in the light intensity received by crops in different locations. Some crops may grow slowly due to insufficient light, while others may be damaged due to excessive light. In addition, the position of the sun changes over time, and some existing greenhouses may not be able to effectively track and adjust the incident angle of light. This results in insufficient or excessive light in different areas of the greenhouse at different times of the day, affecting the photosynthesis efficiency of crops.

[0004] Uneven lighting will have a direct impact on the photosynthesis of crops. Photosynthesis is the process of crops converting light energy into chemical energy and is the basis of their growth and development. If the lighting is uneven, the photosynthesis efficiency of crops will be reduced, resulting in the inability to fully synthesize organic matter, affecting growth rate and yield.

[0005] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing ones on the market, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect.
