[0002] At present, 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 the traditional refrigerant air conditioning, which centrally processes 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 cooling and heating loads of the indoor environment.

[0003] Among them, during the actual use of the central air-conditioning, a dust cover is installed on the surface of the air-conditioning box to prevent dust invasion.

[0004] However, most of the existing dust covers are fixed to the central air conditioners by bolts, and since most of the central air conditioners are installed at high places, when the dust cover needs to be removed, the operator is required to climb a long ladder to remove the dust cover, which greatly increases the risk of installation and removal. Therefore, it is necessary to design a new technical solution to solve the problem, so that the operator does not need to climb a long ladder to remove the dust cover. Utility Model Content

[0009] As an optional solution to the technical solution of the present application, mounting frames are fixedly installed at both ends of one side of the wind shield, and rotating shafts are rotatably installed on one side of the two groups of mounting frames. The two groups of mounting frames correspond to the two groups of abutments respectively, so as to facilitate supporting and limiting one side of the wind shield.

[0010] As an optional solution of the technical solution of the present application, limiting grooves are provided at the four corners of the inner side of the wind shield, and springs can be detachably installed in the four groups of limiting grooves to support the blocks on the filter screen.

[0011] As an optional solution of the technical solution of the present application, a filter is built into the limit groove, and blocks are fixedly installed at the four corners of the filter. The four groups of blocks correspond to the four groups of limit grooves respectively and can fit into the limit grooves.
