Water Quality
Water used with the HP HVAC system must be very pure. Dissolved solids, and impurities
contained in the water will precipitate out when the water evaporates, causing dust and
minerals to be deposited into ducts, and/or the humidified space. Dusting can have adverse
effects on filters, fans, heating and cooling coils, human health, and may promote corrosion and
bacteria growth in ducts.
For this reason only Reverse Osmosis (RO) or De-Ionized (DI) water can be used with a HP HVAC
humidification system. DI water is very aggressive, in applications where DI water is used all
components (including wet section of ducting and drains) must be constructed from stainless
steel.
To ensure that the HP HVAC nozzles do not become blocked or damaged over time, the
following conditions should also be met:
Conductivity: 20 micromhos or less
Ph: 6.2 – 7.5.
Multiple Zones
Oftentimes a single pump package will be used to serve different ducts or zones. In this case
each duct will have its own set of manifolds, valve controller and valve block making it fully
independent of the other zones. The pump should be sized to handle the full flow capacity of all
zones combined to ensure reliable operation.
Care must be taken when laying out the piping between the pump and the valve blocks at each
zone to prevent vibration transmission or water hammering effects. The piping should be
securely supported using appropriate cushion clamps (by others) and long straight runs should
be avoided.
