Inadequate irrigation in water-cooled HVAC systems can have several consequences, including reduced system efficiency, increased energy consumption, and premature equipment failure. Inadequate irrigation can lead to scaling, corrosion, and fouling of system components, which can cause equipment failure and require costly repairs. Additionally, inadequate irrigation can promote biological growth, such as algae and legionella, which can pose health risks to building occupants. Furthermore, inadequate irrigation can result in increased water consumption, which can lead to higher operating costs and environmental impacts.
