Technical Field

[0001] The utility model relates to the technical field of central air conditioners, in particular to a dust-proof and moisture-resistant central air conditioner maintenance device. Background Art

[0002] A central air conditioning system consists of one or more cooling and heating source systems and multiple air conditioning systems. Unlike traditional refrigerant air conditioners (such as stand-alone units and VRV units), this system centrally processes air to achieve comfort. It uses the principle of liquid vaporization refrigeration 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 indoor heating and cooling loads.

[0003] According to the description of a dustproof and moisture-proof central air-conditioning maintenance device disclosed in the patent website (authorization announcement number: CN217274550U), "The utility model discloses a dustproof and moisture-proof central air-conditioning maintenance device, including a moisture-proof protective cover, both sides of one end of the moisture-proof protective cover are fixedly installed with mounting rails, a movable cover plate is movably installed between the two mounting rails, a limiting component is provided at one end of the movable cover plate, both sides of the moisture-proof protective cover are provided with breathable dustproof ports, both sides of the lower end of the inner wall of the moisture-proof protective cover are provided with connecting rails, and the interior of the connecting rail is movably installed with a movable clamping plate through a movable component, and the movable component includes a groove, a slide rod, a support spring, a sliding sleeve and a movable connecting rod. The utility model relates to the technical field of central air-conditioning. The dustproof and moisture-proof central air-conditioning maintenance device solves the problem that the air-conditioning outdoor unit is easily affected by factors such as rain after long-term use, and the air-conditioning outdoor unit cannot be quickly installed and protected."

[0004] In view of the above description, the applicant believes that the following problems exist:
