[0002] Central air conditioning refers to a large air conditioning system, which consists of a main unit and a terminal. The main unit is divided into a water-cooled unit and an air-cooled unit. The terminal equipment mainly consists of an air conditioning unit and a fan coil unit. There is also a type of central air conditioning that uses a refrigerant, Freon VRV air conditioning unit. The central air conditioning vent is the terminal equipment for air supply and return in the central air conditioning system, and is an air distribution device. The air supply vent sends the cooled or heated air to the room, while the return air vent sucks the dirty air back into the room. The two form a whole air cycle, which ensures the indoor cooling and heating effects while also ensuring the cooling and comfort of the indoor air.
