The width length and height of the classified rooms and their layout must be used for hvac calculations.
Clean room hvac design calculations.
Cleanrooms and hvac systems design fundament.
Calculations should be computed by a cleanroom hvac specialist.
A lot of aspects are not taken into consideration for the calculation including but not limited to heat gain number of people the use of a fume hood etc.
This is achieved by supplying more air to the room than is extracted from it.
2 the hvac system the integrity of the cleanroom environment is created by the pressure differential compared with adjacent areas through heating ventilation and air conditioning system.
The air change rate method of calculation is commonly used in cleanrooms with lower cleanliness requirements usually iso 6 to 9 with the air change rate largely based on the level of particles generated by people and processes.
During this technical presentation ashrae fellow and distinguished lecturer wei sun discusses the following.
The bigger the room the more air you need.

Learning points include standards and classifications p.
Supplying airflow in sufficient volume and cleanliness to support the cleanliness rating of the room.
People often forget that the height of the room directly impacts the airflow.
