The Selection of Air Conditioning Control Systems for Cleanrooms

In the purification equipment industry, Guangzhou Cleanroom Construction Co., Ltd. has, through years of intensive efforts, deeply realized that the air conditioning control system in cleanrooms is at the core. This system not only directly affects the comfort of the production environment but is also closely linked to product quality, production efficiency, and the operating costs of enterprises. Today, we will provide a detailed analysis of the key points for selecting air conditioning control systems for cleanrooms, along with some real - world cases of well - known enterprises.

Cleanrooms are special spaces with strict requirements for environmental cleanliness, temperature and humidity, air distribution, and other parameters. During the production or experimental process, any slight fluctuations in environmental parameters can have serious consequences. For example, in precision electronic component manufacturing workshops, even extremely small dust particles may cause product short - circuits or other quality problems. In biopharmaceutical workshops, unstable temperature and humidity may affect the active ingredients of drugs, thereby affecting the quality and efficacy of drugs. Therefore, the air conditioning control system in cleanrooms must have high - efficiency air - filtering capabilities to ensure that tiny particles in the air can be filtered out; precise temperature and humidity control capabilities to keep the temperature and humidity within extremely strict ranges; and stable and reliable operating performance to ensure the continuity of the production process.

The working principle of the constant air volume system is to maintain a constant air supply volume to keep the indoor environment stable. Its advantages lie in its relatively simple structure, relatively low initial investment cost, and relatively easy maintenance. In some small - scale cleanrooms where the production process has a slightly higher tolerance for environmental parameter fluctuations, the constant air volume system can function well. For instance, a small - scale food processing enterprise, [Enterprise Name A], opted for a CAV system in their cleanroom. Since their production process mainly involves packaging and simple processing, with relatively stable environmental requirements, the CAV system met their basic needs at a lower cost. However, when the indoor load changes, the constant air volume system has difficulty flexibly adjusting the air supply volume, which not only easily leads to energy waste but also falls short in precisely controlling temperature and humidity.

The intelligence of the variable air volume system lies in its ability to automatically adjust the air supply volume according to the real - time changes in indoor load, thus achieving precise control of indoor temperature and humidity. This feature enables it to well meet the dynamic environmental requirements of different production processes and can significantly reduce energy consumption. It is especially suitable for large - scale cleanrooms with complex production processes. A well - known automotive parts manufacturing company, [Enterprise Name B], adopted a VAV system in their large - scale cleanroom. Their production lines involve multiple processes with varying heat loads. The VAV system can adjust the air volume in different areas in real - time, ensuring stable temperature and humidity while saving a significant amount of energy. However, the variable air volume system has a relatively high upfront investment cost, and the system debugging and maintenance require professional technicians, which to some extent limits its wide application.

The centralized purification air conditioning system centrally processes the air and then transports it to each clean area through air ducts. This system is convenient for centralized management and monitoring and can effectively ensure the consistency of air quality throughout the cleanroom. By configuring high - efficiency air - filtering devices, the centralized purification air conditioning system can meet high - level cleanliness requirements and is therefore often used in industries with extremely high cleanliness requirements, such as electronic chip manufacturing and biopharmaceuticals. [Enterprise Name C], a leading semiconductor manufacturer, uses a centralized purification air conditioning system in their cleanrooms. This system can guarantee the ultra - high - level cleanliness required for chip manufacturing, with a large - scale air - handling unit that can handle a large amount of air and ensure the air quality in all production areas is consistent. However, its installation and operation costs are high, and once the system fails, the affected area will be relatively wide, which may seriously affect the entire production process.

The split - type purification air conditioning units have the characteristic of flexible installation and can independently control the environmental parameters of each area. For cleanrooms with a relatively scattered layout and small scale, or areas with special process requirements that need to control the environment separately, split - type purification air conditioning units are an ideal choice. A research and development laboratory of a pharmaceutical company, [Enterprise Name D], which has multiple independent experimental areas with different environmental needs, installed split - type purification air conditioning units. Each unit can be adjusted according to the specific requirements of each area, providing a more targeted environmental control solution. However, due to the relative independence of each unit, the coordination and management are more difficult, and the overall energy utilization efficiency is lower than that of the centralized system.
