When you have a lab or a manufacturing facility that needs to stay sterile, called a cleanroom, one of the banes of your existence will be figuring out a cleanroom HVAC system. To be effective, cleanrooms can't have pollutants, chemical vapors, or airborne fungi or bacteria. Because ventilation systems can become homes for mold and bacteria, you'll also need a specific filtration system to keep your cleanroom in the target temperature range required. We can help you plan how to engineer your cleanroom.
Get a Computational Fluid Dynamics (CFD) Analysis
For a complex look at how air is circulating through a given room, get a CFD analysis. This software modeling tool can tell you how to design a new control environment or even diagnose problems with an existing cleanroom HVAC setup. The analysis will identify air pressure and flow through the space you're looking at, which will give you a complex view of the factors that play a role in the environment.
Minimize Volume to Maximize Cleanliness
The bigger your cleanroom, the more difficult it will be to keep contaminants out, and the more expensive the energy required to keep the room at the correct pressure and temperature will be.
If you have the good fortune of being able to design a cleanroom HVAC system, take a careful look at how you can orient and size the space to control your costs. Cleanrooms' extensive requirements for cleanliness make them consume 10 to 100 times more energy than a typical office room, so your overhead will be more controlled with a careful assessment.
Invest in the Right Equipment
Although you will spend more initially, highly efficient machines will pay for themselves quickly. Make sure to also obtain high efficiency filters. You can also purchase variable frequency drives to cut down on your energy use. These adjust HVAC equipment speed to match conditions at a given time. Estimates point to these drives saving around a third of the typical energy consumption of constant speed drives.
