The setting of the fresh air and return air sections is crucial in the design of air conditioning purification systems. Usually, the return air purification device is installed on the ceiling or on both sides of the wall. This device is equipped with a function to adjust the air volume, which can be adjusted as needed.

The air volume of fresh air and return air needs to be adjusted proportionally, and the mixed air is both energy-saving and hygienic. By adjusting the air volume reasonably, the air conditioning purification system not only maintains fresh indoor air, but also achieves greater energy utilization. This design not only meets the requirements of indoor air quality, but also takes into account the aspects of environmental protection and energy conservation.

Relatively speaking, a high-quality air conditioning purification system needs to consider both efficiency and environmental protection. Through scientific design and reasonable air volume adjustment, it provides users with a comfortable and healthy indoor environment. This meticulous design reflects the progress of modern air conditioning purification technology and further reflects people's pursuit of quality of life. So, when choosing an air conditioning system, choosing a system with efficient purification function is very important for improving the quality of life.

When it comes to fresh air systems, in air conditioning systems, the supply air volume of fresh air should account for at least 10% or more of the total air volume. Especially during seasonal changes, increasing the proportion of fresh air and utilizing natural hot or cold air can effectively reduce the operating costs of air conditioning systems and achieve energy-saving effects.

Simply put, when designing an air conditioning system, the importance of introducing fresh air should be fully considered. Properly increasing the proportion of fresh air can not only optimize indoor air quality, but also utilize the temperature changes in the natural environment to reduce energy consumption. This strategy is not only environmentally friendly, but also very effective in reducing operating costs.

In summary, an efficient air conditioning system is not only about simply adjusting indoor temperature, but also needs to balance air quality and energy-saving effects. So, when choosing, it is important to pay attention to the overall performance of the system, ensuring that the fresh air system can achieve a balance between energy conservation and maintaining a comfortable environment. This design idea reflects the progressiveness of modern air conditioning technology and the importance attached to improving the quality of life.

When it comes to the return air and fresh air in the air conditioning system, there are actually two types: primary return air and secondary return air.

A return air is actually a mixture of indoor return air and fresh air sent in from outside, which is then cooled and sent back indoors. And the secondary return air is the return air mixed with outdoor fresh air, but before being sent back indoors, it undergoes cold and heat treatment, and the temperature can be adjusted according to needs.

Let's talk about filters again. Filters can be divided into initial efficiency, medium efficiency, high efficiency, and super high efficiency according to their filtering effects. According to the structure of filters, there are methods such as metal filtration, grid filtration, electrostatic filtration, and fiber cotton filtration. Each filtering method has its own unique advantages and can be selected according to different air quality and environmental requirements.

In short, whether it is primary or secondary return air, or various filters, they are important components of the air conditioning system, which can ensure indoor air quality and provide a comfortable environment. Choosing and using these functions appropriately can maximize the efficiency of the air conditioning system and better meet our daily needs.
