Description

technical field

[0001] The present invention relates to a new type of diffuser for central air-conditioning system and its component parts, that is, decorative pattern or central core, core group, outer frame, etc., and its manufacturing method. Background technique

[0002] In the central air conditioning system, the air is adjusted to the desired temperature at the source and distributed to various locations through the air duct network, and a diffuser is required at each outlet of the air duct.

[0003] Usually these ducts are of square or rectangular cross-section, most likely because they are readily self-supporting and fully adjustable in the roof corners of buildings or vehicles, and the diffusers used at the outlet of the distribution ducts are also square or rectangular in shape .

[0004] A diffuser mounted at the end of an air distribution duct protrudes / exposes from the ceiling of a room or other area where air conditioning is required, so the diffuser can be pa...
