Nonhazardous Chemical Treatments and Smart Monitoring and Control System for Heating and Cooling Systems

摘要

This project developed extensive operating data on corrosion and deposition in cooling towers and steam boilers that are part of heating, ventilating, and air conditioning (HVAC) systems at five military facilities. Environmentally friendly water treatment formulations were investigated. Smart monitoring and control technology provided continuous corrosion monitoring of all systems and also adjusted corrosion inhibitors based on actual corrosion results. This report addresses five important HVAC issues: scale protection, control of algae and bacteria, cycles of concentration, corrosion protection, and water usage and cost. The nonhazardous corrosion inhibitors and the smart control systems resulted in a longer, energy-efficient service life, lower life- cycle operating costs, and reduced risk of environmental contamination.
