Overview
Many emerging HVAC markets have a majority of their populations located in coastal areas. This leads to an increased number of air conditioning applications located in potentially corrosive environments. Environmental factors such as salt mist in sea side locations, add to the corrosive environments. It’s not hard to see that HVAC equipment especially cooling and condenser coils are under threat of accelerated degradation. Corroded HVAC coils not only diminish the heat transfer but also increases the operational costs and the maintenance bills. Prevention is much cheaper than replacing coils or the entire system.
Other than the HVAC equipment, the indoor space equipment is also susceptible to corrosive effects. Over time, even extremely low levels of Airborne Molecular Contamination (AMC) in the parts per billion can cause permanent damage to the sensitive electronic equipment, switchgear equipment, machinery and even the structural elements. Failure to protect your assets may have costly ramifications.
This course is applicable to architects, air-conditioning engineers, controls engineers, contractors, environmentalists and loss prevention professionals. It is assumed that all the readers know the basic functioning of the air-conditioning system.
To receive PDH credit, the reader must pass a multiple-choice quiz consisting of fifteen (15) questions.
