The artificial climate chamber and the large greenhouse are all in a confined space, artificially regulating the internal environmental conditions. What is the difference between the artificial climate chamber and the large greenhouse? What are the main differences?
1, different purposes
Artificial climate chambers are mainly used for environmental testing, ecological research, agricultural research (such as crop breeding, tissue culture, cultivation experiments, plant protection, animal breeding), etc., while the main use of large greenhouses is production, that is, by directly optimizing the environment to promote Crops are of high quality and high yield, so their uses are different.
2, the degree of closure is different
Because the artificial climate chamber has higher requirements for environmental regulation, the artificial climate chamber has better sealing performance and relatively less external influence, while the sealing material used in large greenhouses is relatively less demanding, so the seal is sealed. The degree is significantly weaker than the artificial climate chamber.
3, the size of the area is different, the control accuracy is different
The area of ​​artificial climate chamber is small, the temperature increase and temperature drop are sensitive to the influence of the environment, and the heat is relatively uniform everywhere. The system is a multi-input and multi-output system. The input variables include indoor temperature, indoor humidity, carbon dioxide concentration, illumination, etc. The output variables are temperature, humidity, carbon dioxide concentration, etc., and the variables of the system are not independent of each other, and the control loops of each subsystem are coupled to each other. Control of any of the system's variables will affect other state changes. The size of a large greenhouse is generally determined by the scale of production. Due to the large area, the uniformity of the environment is worse than that of the artificial climate chamber, and the control accuracy is not as high as the climate chamber.
Due to different uses, the development of artificial climate chambers is developing in a highly sophisticated direction. Because large greenhouses mainly serve production, they are mainly aimed at automation, refined management, saving time, labor and effort, so they control The system and scale are completely different. In short, they are completely different facilities and equipment. I hope you don't confuse them.
