Cleanrooms and related controlled environments are widely used in many industrial fields, such as life sciences (including pharmaceuticals, medical devices, hospitals), micro Electronics, aerospace, nuclear industry. The operating area of clean rooms ranges from tens to tens of thousands of square meters, and they have different designs depending on their functions.

Cleanrooms have experienced rapid development and progress over the past few decades, and their increasing energy demands also reflect their rapid development.

The document contains the accumulated experience and practices in cleanroom design, operation and maintenance, aiming to reduce cleanroom energy consumption and the global impact it brings.

The reader is also referred to ISO 14644-4 for the detailed description of the design work.

Although cleanrooms vary widely in function and size, their energy consumption can generally be more than 10 times higher than that of a similar-sized office.

To achieve the required cleanliness level, filtering and conditioning large amounts of air consumes considerable energy, of which fans can account for 35% to 50%. This is the energy consumption required for high-efficiency filters and other air circulation links working under high pressure difference in clean room systems.

The energy consumed by moving air can account for 80% of the total energy consumption of general manufacturing facilities.

In order to maintain the temperature and humidity required for process requirements and personnel comfort in the clean room and to achieve the required pressure in the clean room space, there are other energy Therefore, there is huge potential for energy saving, both in the careful design of new cleanrooms and in the renovation of existing facilities.

The clean room technical measures applicable to all clean room from clean room to clean air device are introduced and introduced, including GB/T 25915.7 this document is based on actual experience, practice, testing, and theoretical calculations.

Make a clear and scientific explanation of the energy-saving effect.

It should be noted that the energy-saving methods and technologies used in this document are universal and suitable for different environments and situations. They are not for specific processes, and does not include related production processes, such as water treatment, furnaces, autoclaves, stress cycle operation, etc. Supply and demand parties and installation the actual conditions under which the cleanroom operates, as agreed upon by the engineers, determine the specific application of these energy-saving methods.

At every stage of the cleanroom life cycle, there are opportunities to optimize system performance and save energy.

It is most effective to build a clean room, but similar energy saving effects can be achieved in an operating clean room.

It can be used individually or in groups.

During the design phase, when there is less information about the building and its process after completion, conservative design can result in over-sizing of individual systems and overly stringent technical requirements.

It is valuable to question these technical requirements and design points at this stage in order to achieve energy efficiency.

When setting up the system to work and testing its performance, there is still an opportunity to adjust the system to the actual conditions of the empty state in order to optimize the system performance.

energy and minimize energy use.

During the working life of the cleanroom facility, the monitoring data can and should be analyzed to further optimize the system and minimize Energy use.
