What is the function of the air return vent of the air conditioner
The air conditioner return vent is used for return air. When the indoor load is certain, the amount of cold air that needs to be delivered to the room is certain. Compared with the fresh air, the indoor air temperature is generally lower in summer, so some air is returned to the air conditioner box through the return duct, and mixed with a small amount of fresh air to make cold air and send it into the room. Compared with using all fresh air for cooling air, it can effectively save energy. Generally, fresh air units are used in conjunction with fan coils. Fan coils cool the indoor air and send it into the room, which is similar to the function of the return duct of the central air conditioner. Due to hygiene requirements, fresh air units are required to send fresh air into the room.
