An air circulation system suitable for use in a closed plant factory

Abstract

The application relates to the technical field of air circulation and plant cultivation, and particularly relates to an air circulation system suitable for a closed plant factory, which comprises a planting room, a main air supply pipeline, a bottom air supply pipeline and an air return pipeline. The main air supply pipeline is arranged on the inner wall of the planting room, the bottom air supply pipeline is arranged on the ground in the planting room and close to the inner side wall of the planting room, the bottom air supply pipeline is communicated with the main air supply pipeline, the bottom air supply pipeline comprises a first bottom air supply pipeline and a second bottom air supply pipeline which are symmetrically arranged with respect to the central axis of the ground in the planting room, the first bottom air supply pipeline and the second bottom air supply pipeline are used for generating relatively flowing air so that the relatively flowing air rises. The air return pipeline is arranged at the central position of the top of the planting room, and the air return pipeline is used for extracting the air rising from the ground in the planting room. The application has the effect that the vertically rising air generated by the bottom convection can make the growth of plants at different positions more uniform.
