Air conditioner air supply and air return system for plant factory

Abstract

The invention discloses an air conditioner air supply and air return system for a plant factory, which comprises an air processing machine set, a horizontal air supply main pipe, a plurality of vertical air supply branch pipes, multiple rows and multiple layers of plant culture frames and a plurality of air return grids, wherein the horizontal air supply main pipe is arranged above a factory building ceiling and is communicated with the air processing machine set, the vertical air supply branch pipes are communicated onto each horizontal air supply main pipe, the plant culture frames are arranged under the factory building ceiling, one vertical air supply branch pipe is arranged between every two rows of culture frames, one independent air condition unit is formed between every upper layer and lower layer of each row of culture frame, each vertical air supply branch pipe supplies air from the side part of each independent air condition unit and outputs the air from two side parts of each independent air condition unit at the front side and the back side, and the air return grids are arranged on the factory building ceiling. The air supply and air return system has the advantages that a high and large space is actually divided into a plurality of independent air condition units, the temperature / humidity uniformity of the the airflow tissue in the region can be easily realized by each unit through a simple technical method, and further, the temperature / humidity uniformity of the airflow tissue in the whole high and large space is ensured.

Description

Technical field: [0001] The invention relates to an air supply and return air system for an air conditioner in a plant factory, in particular to an air circulation system for an air conditioner in a plant factory with multi-layer cultivation racks. Background technique: [0002] "Plant factory" refers to a year-round plant cultivation system through artificial environment control and computerized production management. Plants are planted in a closed space like a factory building, and the temperature, humidity, carbon dioxide, oxygen, fertilizer, nutrients, and light required for their growth are all controlled, and they are no longer affected by the external climate environment. Homogenization and high yield characteristics. [0003] According to the population report released by the United Nations, the global population will reach 9.3 billion by 2050. If we rely on the traditional farming method of relying on the sky, all the available arable land in the world is currently...

AI Technical Summary

Problems solved by technology

[0007] 1. The horizontal air supply main pipe 2 sends air downward through the diffuser 4, resulting in uneven temperature / humidity in the vertical direction

As mentioned earlier, the "plant factory" adopts multi-layer three-dimensional planting, up to 10 layers, the temperature / humidity is uneven, and the environment for the growth of each layer of plants is different, which seriously affects the homogeneous production of the "plant factory"

[0008] 2. There are many airflow dead angles in the horizontal direction, and when plants are in this area, it may cause fatal damage
