Due to the Coronavirus pandemic, our normal life has been interrupted. This means places that we frequent like hotels, malls, office buildings, dorms, etc. may have only sections of the building operating or closed completely. It may not come into mind for the normal person, but the impact that these closures have on HVAC systems cannot be understated. If the microclimates in these spaces are no longer controlled, then the water used will be stagnant.
Water stagnation can affect all types of HVAC and can cause differing amounts of damage to pieces of capital equipment. Stagnant water will also encourage the growth of biofilms – this can cause microbially induced corrosion, fouling, and a safe space for Legionella and other pathogens to proliferate.
