Every time the door opens it adds to the fresh air intake and should be part of this formula. This values are indicative of the capacity of the dehumidifiers. Because different manufacturers use a different condition to measure this value, there is always confusion in selection. The reason is that the Dehumidifiers have different capacity at different temperature and humidity. 30 deg C is the standard reference for most brands.
Some industrial system come with a performance curve chart.
From this exercise, we can see that the graph is very crucial in a proper way of selection. For Desiccant dehumidifier selection, various manufacturers have different methods of selection as desiccant dehumidifiers have a more complicated performance curve.
