In the field of purification, the air treatment methods in air conditioning systems are of vital importance. They are directly related to the air quality and environmental stability of workshops, laboratories and other places, and further affect the production processes and product quality. Today, as a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd., will introduce several common air treatment methods in purification air conditioning systems in detail for you.

Mixed air treatment is a relatively basic and commonly used method. It mixes outdoor fresh air and indoor return air in a certain proportion and then conducts unified treatment. This method makes full use of the cooling and heating capacities of the return air and reduces the energy consumption of the system. For example, in some places where the requirements for temperature and humidity are not particularly strict but there are certain requirements for air cleanliness, such as general electronic assembly workshops, by reasonably adjusting the proportion of fresh air and return air, both air quality can be ensured and energy cost can be saved. The fresh air brings in fresh oxygen and dilutes indoor pollutants, while the return air recovers part of the energy. After mixing, the air undergoes treatment steps such as filtration, heating or cooling to reach a suitable state before being sent into the room.

In an all-air constant air volume system, the air handling unit continuously delivers the treated air to the room at a fixed air volume. Its advantage lies in its ability to provide a stable air distribution and temperature and humidity environment. It is suitable for places with high requirements for environmental control and large spaces, such as the clean production areas of pharmaceutical factories. The air handling unit will conduct strict filtration on the air to remove impurities such as dust and microorganisms, and then accurately adjust the temperature and humidity to ensure that the air quality in the entire area is uniform and meets high standards. However, this method is relatively energy-consuming, and it is necessary to reasonably select models and conduct operation management according to actual needs to achieve a balance between energy conservation and environmental control.

Different from the constant air volume system, the all-air variable air volume air treatment can dynamically adjust the supply air volume according to the actual load requirements in the room. When there are fewer people moving around or the heat generation of equipment changes, the supply air volume can be reduced, thus reducing energy consumption. For example, in the purification areas of modern office buildings, the number of people and the usage of equipment vary in different time periods, and the variable air volume system can adapt well to such changes. Through sensors installed indoors to sense parameters such as temperature, humidity and carbon dioxide concentration, feedback is given to the control system, which then adjusts the rotation speed and air volume of the fan while ensuring the air purification effect, achieving significant energy-saving effects while meeting environmental requirements.

The air-water system combines the advantages of air treatment and water systems. It usually uses cold water or hot water provided by a chiller to treat the air. Through terminal equipment such as fan coil units, local temperature adjustment of indoor air is carried out, while fresh air is treated by an independent fresh air handling unit and then sent into the room. This method is widely used in some places where there are both comfort requirements and purification needs, such as the surrounding areas of operating rooms in hospitals. The fresh air handling unit ensures air quality, and the fan coil units meet the personalized temperature requirements of local areas. Moreover, the water system has a large heat capacity, which can make temperature adjustment more stable and accurate, and also has certain energy-saving advantages.

In this system, fresh air is treated by a dedicated outdoor air unit and then directly sent into the room, and the fan coil units are responsible for the circulation and temperature adjustment of indoor air. The outdoor air unit undertakes all the tasks of fresh air treatment, including filtration, humidification, dehumidification, heating and cooling, etc., ensuring that the fresh air sent into the room is of high quality. The fan coil units flexibly adjust the indoor temperature according to the needs of indoor personnel. The two cooperate with each other and are suitable for places with high requirements for both indoor air quality and comfort, such as the purified guest rooms of high-end hotels. The advantage of this system is that the temperature of each room can be independently controlled, with high flexibility, and the outdoor air unit ensures the overall air purification effect.

Different air treatment methods have their own characteristics and applicable scenarios. In the actual design and application of purification air conditioning systems, it is necessary to comprehensively consider various factors such as the functional requirements of the place, the size of the area, the density of personnel, the heat generation of equipment and the energy cost, and choose the most suitable air treatment method.
