[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioners (such as single units, VRV) that centrally process air to achieve comfort requirements. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the heating and cooling loads of the indoor environment. It is widely used in shopping malls and office buildings. During the installation of air conditioning pipes, a central air conditioning duct structure is required for connection;

[0003] Announcement No. CN211233293U discloses a central air conditioner air duct structure, including a connecting air duct, a ventilation duct is installed on the rear surface of the connecting air duct, and an adjustable air outlet is installed on the lower wall of the inner surface of the ventilation duct. The utility model provides an air duct structure for a central air conditioner with a connecting air duct, a ventilation duct and an adjustable air outlet;
