Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: under the premise of ensuring indoor air quality, the central air-conditioning system can play the functions of energy saving and emission reduction; Indoor gas is continuously recycled. If indoor individuals carry infectious germs, these germs will follow the gas to circulate indoors, which will easily cause collective infection of indoor personnel and endanger health.

Embodiment Construction
[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
[0037] refer to figure 1 , which is a central air-conditioning air circulation system disclosed in the present invention, comprising an air supply main pipe 2, an air inlet main pipe 1, a return air main pipe 3 and a refrigeration unit. One end of 3 is connected, and the ends of the air supply main pipe 2 and the return air main pipe 3 away from the air inlet main pipe 1 are closed. The top of one end of the air inlet main pipe 1 close to the return air main pipe 3 is provided with an air inlet 11 which communicates with the outdoor. A fan coil unit 12 for air to pass through is installed in the ventilation path of the air inlet main pipe 1 , and the fan coil unit 12 is located between the air inlet 11 and the air supply main pipe 2 . The air supply main pipe 2 is connected with a plurality of branch pipes 21 along its length direction. One end of the branch ...

The invention relates to a central air-conditioning air circulation system, which includes an air inlet main pipe, an air return main pipe and an air supply main pipe. The air inlet main pipe communicates with the air supply main pipe and the air return main pipe. The air main pipe is connected with multiple return air pipes. The side of the branch pipe away from the air supply main pipe is equipped with a heat exchange device for cooling the gas. The air inlet main pipe is provided with an air inlet connected to the room. A fan coil unit for air cooling is installed between the air main pipes, a filter assembly is installed in the air inlet main pipe and between the fan coil unit and the air supply main pipe, and the side of the return air main pipe close to the air inlet main pipe is connected to the outside. The exhaust pipe, the fan coil unit and the heat exchange device are all connected with a refrigeration unit, and the inside of the air inlet main pipe and the exhaust pipe are all equipped with a flow limiting mechanism. The air-conditioning system of the present invention can provide fresh air to the room during the period of flu or virus outbreak, so as to ensure the life and health of personnel.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a central air-conditioning air circulation system. Background technique [0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. The principle of liquefied gas refrigeration is used to provide the required cooling capacity for the air-conditioning system, but the function of the central air-conditioning is limited to the regulation of indoor temperature. The fresh air system can circulate the indoor and outdoor air. [0003] Existing, such as China Utility Model Bulletin No. CN208750858U discloses a central air-conditioning system with a fresh air function, including a central air-conditioning system that provides cold and warm air, an arc-shaped air supply duct and a return air system. Insulation flexible pipe and mixing chamber, the return air pipe is connected to the mixing chamber pipe t...
