Abstract (en)
[origin: GB2551714A] A control system for controlling air volume so as to maintain a desired concentration of airborne contamination in a cleanroom. Where the cleanroom is supplied by a HVAC system 12 which supplies treated air to the cleanroom. The control system feature sensing means 48 for sensing a concentration of non-viable particles or viable particles in real time or near real time. Processing means are also provided for comparing the sensed concentration of non-viable particles or viable particles against the desired concentration of airborne contamination and outputting at least one control signal to the HVAC system 12 based on the comparison. Optionally, the processing means receives energy price data or usage data. Optionally, there is provide one or more secondary sensing means for sensing an environmental condition or process condition or HVAC system condition in real time or near real time.
