Description

Technical Field

[0001] The utility model relates to the technical field of artificial climate chambers, in particular to an air supply airflow circulation structure for an artificial climate chamber. Background Art

[0002] An artificial climate chamber is an artificially simulated cultivation chamber that controls and adjusts various environmental factors (such as temperature, humidity, light, CO2 concentration, etc.) according to the growth needs of different plants to ensure stable plant cultivation operations.

[0003] The existing patent document with technical authorization announcement number CN215892716U provides an artificial bioclimatic chamber with precise and uniform temperature control and cyclonic airflow. The utility model derives a temperature control model for the crop artificial climate chamber, providing a theoretical basis for precise temperature control of the crop artificial climate chamber; proposes three signals that temperature control must be based on: solar radiation, heat transfer flow of the enclosure structure and indoor temperature, and provides corresponding temperature difference values; introduces an embodiment; the theoretical and technical innovations of the utility model are of great significance and practical value.

[0004] However, the existing air supply circulation structure for the artificial climate chamber is not convenient for filtering the air input into the artificial climate chamber when in use, and is not convenient for filtering the air circulating inside the artificial climate chamber. When the external air is input into the artificial climate chamber, when the external air quality is poor, it is easy to pollute the internal environment of the artificial climate chamber. During the circulation of the air flow inside the artificial climate chamber, the growth of plants causes the air inside the artificial climate chamber to contain certain impurities. If the impurities are not filtered, the circulating flow of the air flow will easily cause the accumulation of impurities and lead to the blockage of the pipes, which directly affects the stable operation of the air supply operation of the artificial climate chamber.
