The Difference Between Cleanroom Air Conditioning And General Air Conditioning

Cleanroom air conditioning is one kind of air-conditioning project, which not only has certain requirements for indoor air temperature, humidity and wind speed, but also has higher requirements for the number of dust particles in the air and the concentration of bacteria. Therefore, it not only has special requirements for the design and construction of the ventilation project, but also has special requirements for the design and construction of the building layout, material selection, construction process, building practices, plumbing, heating, electricity, ventilation and the process itself, as well as the corresponding technical measures and its cost is also increased accordingly.

1. Main parameter control

General air conditioning focuses on temperature, humidity, fresh air supply, while the Clean Room air conditioning focuses on controlling the dust content of indoor air, wind speed, the number of air changes.

2. Air filtration means

General air conditioners have only coarse primary filtration, the higher requirements are coarse secondary filtration treatment. And cleanroom air conditioning requires three-level filtration that is coarse, medium, high-efficiency three-level filtration or coarse, medium, sub-high efficiency three-level filtration. Biological clean room in addition to the air supply system has a three-tier filtration in the exhaust system in order to eliminate the animal's special odor and avoid pollution of the environment according to different circumstances need to be set up two high-efficiency filtration or filtration adsorption filtration.

3. Indoor pressure requirements

General air conditioning on the indoor pressure without special requirements, and clean air conditioning in order to avoid the penetration of outside contaminated air or different production workshops of different substances affect each other, the positive pressure value of different clean areas have different requirements.

4. Material, process, environment and other requirements

Clean air-conditioning system materials and equipment selection, processing technology, processing and installation environment, storage environment of equipment components in order to avoid contamination by the outside world, there are special requirements. This is the general air-conditioning system does not have.

5. Requirements for airtightness

General air-conditioning system on the system's airtightness, air permeability requirements, but the requirements of clean air-conditioning system than the general air-conditioning system is much higher than the means of detection, the standards of each process have strict measures and testing requirements.

6. Other requirements

Cleanroom air conditioning on the evaluation of the quality of the building in addition to the general appearance of the building and other requirements, but focusing on dust, dust, leakage prevention and to avoid the penetration of contaminated air from outside. In the construction process arrangement and overlap requirements are very strict, in order to avoid cracks caused by leakage.
