HVAC Energy Conservation through Cooling Water Treatment

COURSE NO: M05-013
HVAC Energy Conservation through Cooling Water Treatment
Course Highlights

This online engineering PDH course provides an overview of the waterside problems specific to HVAC systems. It briefly discusses how the energy is dissipated from the open recirculation systems and how effective implementation and tight monitoring of the water treatment programs can conserve energy.


Cooling water is a vital utility for large air-conditioning systems. Use of good quality water or proper water treatment can cut your water, energy, and maintenance costs substantially. The savings are associated with the prevention or removal of scale built up on a heat exchange surfaces where even a thin film of 1/32" or 0.8mm can increase the energy consumption by nearly 10%. Perhaps most important of all, it can save you the cost of fixing or replacing equipment that's been damaged by inadequate water treatment; including the downtime and lost revenue usually associated with solving such problems.


The 5 PDH  online course is applicable to mechanical engineers, HVAC designers, contractors, facility managers, O&M personnel who are responsible for operation and design of efficient HVAC systems.
