Clean Rooms Comfort Rate
Clean room operators usually work in better conditions than those required by the standards for normal work environments, since temperature, relative humidity, overpressure and air quality, for intrinsic needs of controlled contamination environments, are maintained constant and with stricter parameters than those of optimal microclimate conditions.
However, the need to hyper-ventilate the environments to keep the quantity of air-transported particulate under control or to dissipate the thermal energy generated by the high-tech production processes, could generate discomfort for the operators due to excess ventilation.
The Comfort-Rate therefore introduces a tool for assessing the comfort of environments subjected to forced hyper-ventilation: Clean Rooms.
There are 6 Comfort-Rate reference classes: the classes are assigned according to the quality of the ventilation and air distributions systems of the Clean Rooms.
The functional parameters taken into consideration for determining the Comfort-Rate are:
- the temperature of the air which enters the Clean Room;
- the desired environmental temperature;
- the coverage factor.
