[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 conditioning and centrally processes air to meet 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. 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 the entire air cycle, which ensures the indoor cooling and heating effects while also ensuring the cooling and comfort of the indoor air.
