Dust Free Clean room is a specially designed space that can effectively guarantee product reliability and personnel health, and is widely used in electronics, pharmaceutical, medical, aerospace, food and other fields. However, clean rooms need to carry out fine control of indoor environmental parameters during operation, and their energy consumption is much higher than that of ordinary buildings at the same scale. So how to save energy has become an important issue for everyone to care about.

First, we need to know clean room energy consumption composition.

The energy consumption of ISO clean room is mainly composed of energy consumption for heat and humidity treatment, energy consumption of purification treatment equipment, energy consumption of process equipment and other energy consumption.

1) Energy consumption of hot and wet air treatment

The control of temperature and humidity in the clean room is extremely strict, and its control is related to whether the product can be normally produced. Due to the high precision requirements, strict envelope structure, many process zones,the energy consumption is huge.

2) Energy consumption of air purification treatment

The purification of the air requires the use of various filters, including coarse, medium, high efficiency, and ultra-high efficiency filters, which are used to control suspended particles in the air; Chemical filters are also used to control gaseous molecular pollutants in the room. These filters will produce a lot of resistance and consume a lot of energy, so clean room fresh air, return air, exhaust air system is also an important part of clean room energy saving.

3) Energy consumption of process equipment

In order to achieve higher and more stable production accuracy, the energy consumption of equipment used in production is also rising.

4) Other energy consumption

Clean room lighting, water treatment, compressed air, mass gas and other energy consumption.

For the energy-saving problem of clean room, it is recommended to start from the following aspects:

1) According to the actual needs of the process, reasonably determine the cleanliness level, self-cleaning time, pressure difference, temperature and humidity, illumination, utilization rate, etc., to avoid excessive design.

2) Effectively identify the relevant pollution sources in the clean room, reasonably evaluate and analyze their emission intensity, optimize the air flow organization, and reasonably design the air supply volume.

3) For the key control area of high cleanliness level, local purification equipment should be used as far as possible to reduce the area of high cleanliness area. FFU products are designed for this scenario and have been widely used. 

    

4) Set adaptive control system to adjust air volume according to pollutant control needs.

5) Strengthen the training of operators to effectively reduce personnel pollution.

6) Develop a filter replacement and equipment maintenance plan to maximize the low resistance of the filter and the maximum efficiency of the air conditioning ventilation system equipment.

7) Good daily cleaning can effectively reduce indoor pollution load and thus save energy.
