Problems solved by technology

The current problem is: on the one hand, blowing by the fan will cause CO 2 The concentration is uneven, and the simulation environment is not real, which leads to inaccurate research results; on the other hand, the height of the climate chamber is generally 3 meters, and as the plants grow, there may be problems exceeding the height of the climate chamber, which will cause trouble for subsequent research

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] see figure 1 and figure 2 , the present invention is suitable for CO 2 , O 3 An open-top climate chamber with uniform concentration release, including: enclosure structure, gas regulation system and control system.

[0044] The enclosure structure includes an underground part and an aboveground part; the underground part of the enclosure structure is a ring beam 1 constructed of reinforced concrete to ensure the convenience and strength of installation. The skeleton 2 of the above-ground structure is fixed by the pre-embedded anchor bolts on the ring beam 1, so as to ensure that the original ecological system is not damaged as much as possible and reduce the impact on plant growth. Skeleton 2 is fixed by aluminum alloy profiles and connected into a regular eleven-sided column frame with a diameter of 4 meters and a height ...

Abstract

The invention discloses an open-top climate chamber and a gas uniformity simulation verification method thereof. The open-top climate chamber comprises an enclosure structure, a gas regulation and control system and a control system, the enclosure structure comprises an underground part and an overground part; the overground part forms an open top type air chamber; the gas regulation and control system comprises a gas steel cylinder and a gas distribution pipeline. The gas distribution pipeline comprises a main pipeline and a branch pipeline; a pipeline fan is arranged on the main pipeline; the main pipeline is respectively communicated with the gas steel cylinder and the branch pipeline; the control system comprises a controller and a gas concentration sensor; the output end of the gas concentration sensor is connected with the input end of the controller, and the output end of the controller is connected with the signal input end of the pipeline fan. Through reasonable layout of themain pipeline and the branch pipelines, uniform release of gas concentration in the climate chamber can be realized; a simulation result proves that the gas concentration uniformity is good, so that areal external environment is simulated, and a technical support can be provided for a plant growth test.

Description

technical field [0001] The invention belongs to the technical field of open-top climate chambers, in particular to an open-top climate chamber and a gas uniformity simulation verification method thereof. Background technique [0002] Studies have shown that the concentration of carbon dioxide in the earth's atmosphere reached 405ppm in 2017, and it is predicted that it will reach 650 to 970ppm by 2100. In order to study the impact of changes in the gas content in the air on the growth of plants, the researchers used various methods to simulate the changes in the gas content in the atmosphere. To measure plant growth and soil changes to evaluate the impact of gases, especially carbon dioxide, on plant growth, and to systematically study plant growth, ecological buildings, and efficient use of solar energy, which have important theoretical significance for the survival and development of plants It also has great engineering application value. [0003] Currently, the simulate...
