Comparison and Selection of Different Types of Air - Supply Ceilings
2025.02.05
Hello everyone! We are Guangzhou Cleanroom Construction Co., Ltd. As a professional manufacturer of purification equipment, we are well aware of the importance of air - supply ceilings in the environment of purification workshops. Today, we will discuss the comparison and selection of different types of air - supply ceilings with you, helping you create an ideal purified space.
I. High - Efficiency Air - Supply Outlet Type Air - Supply Ceiling
1. Structure and Principle
The high - efficiency air - supply outlet type air - supply ceiling mainly consists of a static pressure box, a high - efficiency filter, and a diffuser plate. Air first enters the static pressure box and is evenly distributed inside. Then, it passes through the high - efficiency filter for high - precision filtration and is finally evenly sent into the room through the diffuser plate. This structure ensures that the air sent into the room has an extremely high cleanliness level.
2. Performance Characteristics
· High Cleanliness: The equipped high - efficiency filter can effectively filter tiny particles in the air. The filtration efficiency for particles with a particle size of ≥0.3μm can reach over 99.97%, which is very suitable for places with extremely high cleanliness requirements, such as purification workshops in the pharmaceutical and electronic chip manufacturing industries.
· Uniform Airflow Distribution: The design of the diffuser plate enables the air to be evenly diffused to every corner of the room, reducing the dead corners of indoor air flow and ensuring the consistency of indoor air cleanliness.
3. Application Scenarios
It is suitable for production and research environments with extremely strict requirements for air quality, such as operating rooms and sterile laboratories. These places need to strictly control the number of dust particles and microorganisms in the air to ensure the success rate of surgeries or the accuracy of experimental results.
II. Perforated Plate Type Air - Supply Ceiling
1. Structure and Principle
The perforated plate type air - supply ceiling has small holes opened on a metal plate according to certain rules, and air is evenly sent into the room through these small holes. Its principle is based on the static pressure principle of air. By reasonably designing the aperture, hole spacing, and hole arrangement of the perforated plate, the uniform delivery of air is achieved.
2. Performance Characteristics
· Aesthetically Pleasing: The perforated plates come in various shapes and can be customized according to the interior decoration style, not only meeting the purification requirements but also enhancing the overall aesthetics of the room.
· Relatively Low Price: Compared with some air - supply ceilings with complex structures, the manufacturing process of the perforated plate type air - supply ceiling is relatively simple, with a lower cost, which can reduce the overall cost of the purification project to a certain extent.
· Limited Wind Speed Adjustment Range: Due to its structural characteristics, it is less flexible in adjusting the wind speed than some other types of air - supply ceilings, and its ability to precisely control the indoor air flow is slightly weaker.
3. Application Scenarios
It is suitable for places with certain cleanliness requirements but are cost - sensitive, such as food processing workshops and ordinary electronic assembly workshops. These places need to ensure a certain air quality while also considering cost factors, and the perforated plate type air - supply ceiling is a more suitable choice.
III. Swirl Diffuser Type Air - Supply Ceiling
1. Structure and Principle
The air outlet of the swirl diffuser type air - supply ceiling is spiral - shaped. When the air is sent out from the air outlet, a swirling air flow is generated. This swirling air flow can quickly mix with the indoor air, making the indoor temperature and humidity distribution more uniform. At the same time, it can also effectively discharge the dirty air in the room.
2. Performance Characteristics
· Good Mixing Effect: The unique swirling air flow design can make the fresh air sent in fully mix with the indoor air in a short time, quickly improving the indoor air quality.
· Flexible Installation Height: Compared with other types of air - supply ceilings, the swirl diffuser type air - supply ceiling has relatively low requirements for the installation height and can also perform well in some places with limited space.
· Relatively High Noise: Since the air is sent out in a swirling manner, a certain amount of noise will be generated during operation. Sound insulation measures need to be considered when using it in environments with strict noise requirements.
3. Application Scenarios
It is suitable for some places with high requirements for air mixing effects and temperature uniformity, such as large - scale industrial plants and stadiums. In these places, rapid air mixing and uniform temperature distribution are crucial for the comfort of personnel and the stability of the production process.
When choosing an air - supply ceiling, multiple factors such as the cleanliness requirements of the place, budget, space characteristics, and noise control need to be comprehensively considered.
