How to Control the Three Uncontrollable Factors of Constant Temperature and Humidity Ultra Clean Room
A super clean room refers to a cleanroom that is super clean and contains small particles, bacteria, and other substances within a certain spatial range that meet the corresponding standards. No matter how it changes, the cleanliness still meets the standards over time. And the constant temperature and humidity ultra clean room, first of all, belongs to the constant temperature and humidity room, which requires precise control of temperature and humidity. However, because its requirements meet the standards of ultra clean rooms, the construction difficulty of the constant temperature and humidity ultra clean room project is even greater.
1. Dust emission control
Since it is an ultra clean room, besides reaching the relevant cleanliness level when starting the project, it is also necessary to maintain the cleanliness level during daily maintenance because the cleanliness level is extremely high. Without special treatment methods, the cleanliness level will definitely decrease. Normally, we may not deliberately care about controlling the amount of dust emitted, such as our clothes, human hair, and skin, which may emit fine particles at any time and anywhere.
2. Control of bacterial growth rate
In addition to lifeless dust, there are also living bacteria, which require even higher levels of bacterial production. This is because a person can emit 4000-62000 bacteria per minute when sneezing, and up to 70-700 bacteria per minute when coughing.
3. Temperature and humidity control
The control of temperature and humidity is an important factor that must be controlled in our constant temperature and humidity engineering, but here the requirements are even higher when combined with the ultra clean room. Note that our constant temperature and humidity engineering usually refers to constant temperature and humidity air conditioners, as well as related harmonious structures and equipment instruments. As we mentioned earlier, the constant temperature and humidity ultra clean room requires control over the amount of dust and bacteria generated. Therefore, the normal constant temperature and humidity air conditioning and related systems used to be unsuitable because there is communication with the outside air flow, and the equipment itself will also produce dust and bacteria. We can tell from the air conditioner we use in our household that it needs to be cleaned every once in a while, as the inside is very dirty. Our constant temperature and humidity ultra clean room's constant temperature and humidity air conditioner cannot be operated in this way, and it is not allowed to have such a large amount of dust and bacteria. So our constant temperature and humidity air conditioning system needs to add self-cleaning function, not only to control its own dust and bacterial emissions, but also to have filtering and cleaning function before exchanging other gases with the outside air.
Overall, the constant temperature and humidity ultra clean room project is classified as a relatively high-end constant temperature and humidity project and a high difficulty clean project, with considerable technical barriers. We hope to be aware of this before undertaking this project and carefully consider all aspects!
