Introduction
HP HVAC (Adiabatic Humidification System)
Congratulations on the purchase of your NORTEC HP HVAC humidification system. This system
was designed to be efficient and reliable, and is manufactured from high quality materials to
provide long trouble free operation. In order for the system to operate as intended it must be
installed properly.
This guide details the design, installation, commissioning, operation, and troubleshooting of the
HP HVAC system. Please take the time to familiarize yourself with this guide before beginning to
ensure that the system is installed the way it was designed. This ensures a long and trouble
free life of the humidifier.
About HP (Adiabatic Humidification System)
The HP (High Pressure) HVAC system is designed to be installed inside an AHU or duct system to
humidify air to a desired relative humidity. Proper humidity levels have been shown to be
important for health and comfort of occupants. Maintaining proper humidity is also important
for many industrial and manufacturing processes.
The HP system uses a series of nozzles to spray a very fine mist of water droplets into an air
stream. During this process the air absorbs moisture increasing its relative humidity levels. As
the water droplets evaporate, they absorb some energy in the form of heat from the air. This
loss of heat causes the air temperature to drop, resulting in a phenomenon known as adiabatic
cooling.
The HP HVAC adiabatic system has 2 effects:
 The relative humidity of the air increases (humidification)
 The temperature of the air falls (adiabatic cooling)
Humidification of the air is the main goal of the HP HVAC system. The cooling of the air is
secondary and is frequently beneficial since it is „free‟ cooling. In cases where air-cooling is un-
desired, preheating of the air is required.
In general a HP system has the following advantages over other humidification technologies:
 Low frequency of maintenance, since there are few moving or expendable parts.
 Replacing components is quick and requires minimal system disassembly.
 A „free‟ air-cooling benefit from water extracting latent heat from the air.
