Controls for Commercial Kitchens [Air-flow]
In the latter scenario, the hoods should be equipped with automatic balancing dampers and should be capable of measuring the flow rate in the hood. Each kitchen should also include a Variable Air Volume (VAV) box that can measure and vary the replacement air flow rate. The exhaust fan and replacement air unit must also be able to operate at variable speed based upon the number of kitchens in operation. At the core of these mechanical components is the controller – the brain of the system.
When cooking is sensed, rather than simply turning on the exhaust to full power, the controller will exhaust at the minimum rate required based on the heat given off by the appliance. This is accomplished by adjusting the speed of the exhaust fan and the hood damper simultaneously.
At the same time, the controller will provide the proper amount of replacement air using the same technique to keep the kitchen balanced. As additional kitchens turn on and others turn off, the controller must be capable of measuring and adjusting in real time. While this sounds straightforward, it’s important to carefully vet your controls supplier to ensure their system has the necessary capabilities.
