The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In the description of the present application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate an orientation or a positional relationship based on the drawings, which are merely for convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or display that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or display.

A detailed description of a high-precision return air system for greenhouse return air according to embodiments of the present application will be provided below with reference to fig. 1-2. It is noted that the following examples are merely for explaining the present application and are not to be construed as limiting the present application.

Example 1:

as shown in fig. 1-2, a high-precision return air system for return air of a greenhouse 2 comprises: a greenhouse 2 room and a high-efficiency air supply unit 1; the greenhouse 2 room has at least four side walls; the efficient air supply unit 1 is arranged at the top of a room of the greenhouse 2, and preferably, the efficient air supply unit 1 is arranged at the center of the room of the greenhouse 2. The greenhouse 2 is supplied with air by adopting a top efficient air supply port, the air return devices 4 are arranged at the lower part of each side wall of the greenhouse 2 room, and each air return device 4 is connected with an exhaust system.

The air return device 4 comprises an air return plate 5, a filter screen 6 and an air return pipe 3, wherein the air return pipe 3 is embedded in the side wall of the greenhouse 2, the air return plate 5 is embedded in an opening of the side wall, the filter screen 6 is arranged on the air return plate 5, one end of the air return pipe 3 is connected with the air return plate 5, and the other end of the air return pipe is connected with an exhaust system.

The greenhouse 2 is arranged in such a way that the air sent out from the high-efficiency air supply unit 1 can be sent out from a plurality of air return devices 4 arranged at the lower part of the greenhouse 2, the air sent out from the center is dispersed to each air return device 4 at the lower part of the side wall, and a conical air supply curve from head to foot is formed in the greenhouse 2, so that the temperature difference between the upper part and the lower part in the greenhouse 2 is more uniform.

Meanwhile, the return air pipe 3 is embedded in the wall, and the temperature can be transmitted to the side wall through the return air pipe 3, so that the upper temperature and the lower temperature in the greenhouse 2 are further assisted to be agreed.
