If you need an enclosed and controlled environment for clean zones, a clean room may be your good choice. A clean room is a local air purification equipment, which can provide an environment at a higher cleanliness class. It is good at dust control, sound control and safety. It can be built and install quickly. If you are interested in the process of creating a clean room, the following details may provide some help.

First, we should know which size of the clean room we are in need. We need to evaluate how many people and how much material flow in the clean room. The space should include the personnel access doors and pathways.

Second, we should choose a clean room classification according to our need. According to the institute of Environmental Science and Technology Standard 14644-1, there are different cleanliness classifications and the allowable number of particles at different particle sizes. Choose a right classification can help us maintain the clean room, and cost less energy.

Third, it is necessary to maintain a positive air space pressure which can avoid the contaminants to enter into a clean room. As we know, the higher space pressure differential means a higher energy cost, and it requires more force if we want to open or close the door.

Forth, as each clean classification has its own air change rate, so it is necessary to take this factor into account. We should determine what kind of the air change rate to be used.

At last but not the last, we should perform the cleanroom heating or cooling calculations includes filtration, humidifier manifold heat,process load, recirculation fan heat and so on.
