What are artificial climate chambers used for? What is the difference between it and an environmenta

The closed isolation equipment that can manually control factors such as temperature, humidity, wind speed, cleanliness, air pressure and gas composition is called an artificial climate chamber, also known as an environmental chamber (environmental cabin). The artificial climate chamber is not limited by external natural conditions such as geographical location and seasonal conditions, which can shorten the research cycle and serve as an important equipment for scientific research, teaching and production.

It is composed of three parts: the control platform, the air handling unit and the controlled environment experimental cabin. The control platform is equipped with a regulator and a secondary instrument for controlling various parameters of the artificial climate chamber, the regulator displays the set value of various environmental parameters required by the artificial climate chamber, and continuously detects the deviation between the actual value of the artificial climate chamber and the positive fixed value according to the secondary instrument, and automatically sends out the regulation signal to transmit to various actuators (such as heat source, cold source, fan, water pump, gas composition control system, etc.) for action; The air handler is equipped with various regulating equipment such as air filters, heating and cooling coils, humidifiers and dehumidifiers, which act according to the instructions of the regulator in the control room; The environmental experiment chamber is usually equipped with an electric light source and an inductive element to monitor factors such as temperature, humidity, cleanliness, gas composition, etc., and is connected with a secondary instrument to transmit the actual value of each sensing to the regulator transferred to the control platform for difference identification. This route is repeated so that the actual value in the climate chamber is the same as the positive fixed value on the regulator.

The artificial climate chamber is used to study the influence of environmental conditions on biological life activities, including the cultivation, domestication, breeding and other work of organisms, and can also measure the performance of other thermal and humid environment control equipment. The small ones are called "artificial climate chambers", "environmental chambers", etc.

History. In June 1949, Professor Winter, a famous American botanist and horticulturist, presided over the construction of the world's first plant artificial climate chamber in Pasadena, California. The emergence of artificial climate chambers has brought a revolutionary change to the field of biology, greatly accelerated the process of biological research, and attracted great attention from all countries in the world. Subsequently, nearly 20 countries have successively established artificial climate chambers (boxes) of different scales and types.

Among them, the fastest growing is Japan, with more than 70 artificial climate chambers of various types; Artificial climate chambers have been spread to agricultural technology stations in various prefectures and prefectures in Japan.

The research on the monitoring and control of artificial climate chambers in China started relatively late, but the development speed is relatively fast. In 1969, the Shanghai Institute of Plant Physiology, Chinese Academy of Sciences built a large-scale plant artificial climate room, with a total of 25 natural light rooms and artificial light rooms. In addition, China has also produced several types of artificial climate chambers, which are the earliest artificial climate chambers in China, which can be used for research on plants and microorganisms under specific environmental conditions.

However, compared with the technical level of foreign countries, the research of artificial climate chambers in China is still in its infancy.
