Cleanroom chiller, the chiller, has a dual function in air treatment. The temperature and relative humidity of the room air must be monitored. We make agreements in advance about the limits within which this should happen. These agreements are based on outdoor conditions. If the climate changes because the summers become warmer and the winters colder, we will also have to adjust these values.
What determines cleanroom relative humidity? Usually the question is answered by the product being machined, assembled or produced. For example, effervescent tablets are very sensitive to moisture or the paper strip in the Carona test. In the pharmaceutical or food industry, the moisture percentage affects the sterility of the room. Depending on the cleanroom application, the relative humidity is determined.
Cleanroom chiller supplies cold water of a temperature that guarantees adequate dehumidification. Usually this temperature is too low for a pleasant working environment. The temperature of the dehumidified air must be heated.
Cleanroom chiller uses energy to cool, but heating is needed to then make the room temperature comfortable again. Thus, double energy is used: cooling and heating.
Cleanroom chiller, the capacity of the chiller is selected on what is needed to dehumidify the freshly drawn outside air and what is needed to compensate for the internal heat load. A high recirculation rate of cleanroom air keeps energy costs low and if possible; place all equipment that generates heat outside the cleanroom.
