A steam humidifier for an AHU on a job Im reviewing shows its served by medium temperature hot water, so its not electric. The design drawing shows a control valve on the MTHW line as it enters the humidifier.
What exactly control the units operation? Is it just the space humidity sensor that controls the operation of the control valve. Is it that simple, or is there more to it.??
