What is Air Change ? Air Change Rate
 
Air change is the amount of air required to completely replace the air in a defined space within the factory. The approach to Open Space Cooling is two prong. First is to reduce the temperature of the supply air and second create an air change within.
The rate of air change depends on the type of production process. The table to the left shows the recommended designed air change for various types of work processes.
Air change rate is a unit of measurement that compares the amount of air moving through a defined space to the volume of the space. It is usually expressed as:
Air Change Rate is calculated to determine how well a space is ventilated compared to the recommendations set for the type of industrial workspace.
