How to distinguish the air outlet and return vent of air conditioner

1. The difference between air-conditioning outlet and return vent
1. Different positions

The positions of air-conditioning outlet and return vent are different. Generally speaking, the outlet is located above the room to discharge cold air, while the return vent is generally located below the room to inhale indoor air.

2. Different functions

The functions of air-conditioning outlet and return vent are also different. The outlet sends out cold air for cooling or heating, and sends the adjusted temperature into the room. The return vent inhales the air in the room, filters and processes it before sending it out.

3. Different composition

The composition of air-conditioning outlet and return vent is also different. The outlet is mainly composed of air outlet, guide plate and air duct, while the return vent is mainly composed of filter, air duct and return vent.

2. The functions of air outlet and return vent
1. The function of air-conditioning outlet

The air-conditioning outlet sends cold air or hot air from the air-conditioning host into the room to make the indoor temperature reach the set temperature. The air outlet can be divided into many types such as upper air supply, lower air supply, and side air supply. Indoor air circulation is carried out through different air supply methods, which not only improves the indoor air quality but also plays a role in dehumidification.

2. The role of the air conditioner return air outlet

The air conditioner return air outlet sucks the indoor air into the air conditioning system, filters it, sends it back to the host for processing, and finally sends it back to the room. The return air outlet will conduct air quality detection. If the air quality is not good, the indoor air will be purified.

3. How to judge the air outlet and return air outlet of the air conditioner

1. Look at the position

The positions of the air outlet and the return air outlet are different. The air outlet is usually set above the room, while the return air outlet is set below the room.

2. Look at the shape

The shapes of the air outlet and the return air outlet are also different. The air outlet may be larger and rectangular or square in shape; while the return air outlet is usually smaller and rectangular in shape.

3. Look at the function

The functions of the air outlet and the return air outlet are also different. The air outlet sends out cold or hot air and circulates it in different ways to achieve dehumidification, heating, cooling, etc., while the return air outlet mainly filters and processes the air and sends the air back to the air conditioner host for processing.

In short, the air outlet and return air outlet of the air conditioner are very important components of the air conditioning system. Understanding their differences and functions will help to better use and maintain the air conditioning system.
