Embodiment 1

[0034] Such as figure 1 As shown, Embodiment 1 of the present invention provides a return air system of a central air conditioner, which includes an air conditioner return air outlet 7; also includes an indoor ceiling unit; The keel 2, the hanger 3 connected to the keel 2, the top of the hanger 3 is connected to the indoor roof; the indoor ceiling unit is provided with a through hole 5 that runs through the mineral wool board 1, and the through hole 5 The bottom end communicates with the air-conditioning return air outlet 7 through a connecting pipe 6, and the mineral wool board 1 is used to filter the gas entering the air-conditioning return air outlet 7; wherein, the above-mentioned connecting pipe 6 is preferably a connecting hose.

[0035] In the specific operation, the mineral wool board 1 is a plate with good air permeability. The above-mentioned indoor ceiling unit setting can make the gas entering the return air outlet 7 of the air conditioner pass through the mineral ...

Embodiment 2

[0047] Embodiment 2 of the present invention provides a central air-conditioning return air system. The main structure is similar to Embodiment 1, and also includes an indoor ceiling unit; for the specific settings of the main structure, please refer to the records in Embodiment 1. This time it is intended to illustrate difference between the two.

[0048] In this embodiment, the above-mentioned adsorption material coating includes a diatom ooze coating, and the thickness of the diatom ooze coating is preferably 3 mm.

[0049] In the specific operation, the above-mentioned diatom ooze coating can also realize the adsorption operation of harmful substances, and then can realize the air purification operation, and finally can improve the quality of the gas input to the return air outlet of the air conditioner.

[0050] In this embodiment, the diatom ooze coating is provided with block activated carbon inside.

[0051] In specific operations, the above-mentioned block activated ...

Embodiment 3

[0053] Embodiment 3 of the present invention provides a central air-conditioning return air system. The main structure is similar to Embodiment 1, and also includes indoor ceiling units; for the specific settings of the main structure, please refer to the records in Embodiment 1. This time it is intended to explain difference between the two.

[0054] In this embodiment, the above-mentioned adsorption material coating includes a bio-enzyme coating, and the thickness of the bio-enzyme coating is preferably 1 mm.

[0055] In the specific operation, the above-mentioned biological enzyme coating can also realize the adsorption operation of harmful substances, and then realize the purification operation of the air, and finally improve the quality of the gas input to the return air outlet of the air conditioner. The principle of the above-mentioned biological enzymes for removing formaldehyde is that microorganisms can produce biological enzymes through their own reproduction. Under...

Abstract

The invention discloses an air return system of a central air conditioner. The system includes an air-conditioner return air inlet and an indoor suspended ceiling unit. The indoor suspended ceiling unit comprises a mineral wool board, a keel connected with the mineral wool board and a hanging piece connected with the keel, and the top of the hanging piece is connected with an indoor roof; the indoor suspended ceiling unit is provided with a through hole running through the mineral wool board, the bottom of the through hole is communicated with the air-conditioner return air inlet through a connecting pipe, and the mineral wool board is used for filtering gas entering the air-conditioner return air inlet.

Description

technical field [0001] This application relates to but not limited to the technical field of building materials, especially a central air-conditioning return air system and central air-conditioning. Background technique [0002] In the prior art, central air conditioners have the advantages of economy, energy saving, environmental protection, and long service life, and are widely used. With the gradual deterioration of the environment, more and more users hope that the central air conditioner has excellent air filtration function. [0003] However, the current central air conditioner can only realize the air filtration operation through the internal filter element layer, the filtration capacity is greatly limited, and it cannot effectively meet the needs of users. Contents of the invention [0004] The technical problem solved by this application is to provide a central air-conditioning return air system and central air-conditioning, which can effectively overcome the def...
