Why do water, steam, and refrigerant coils fail?
Coil failure is a common issue in many industrial and commercial settings, and it can have significant consequences for the efficiency and effectiveness of HVAC systems. Understanding the most common causes of coil failure can help facilities managers and HVAC technicians prevent and mitigate these issues.
One of the most common causes of coil failure is plugging, which occurs when dirt and other debris build up on the coil, reducing its ability to transfer heat effectively and increasing the air pressure drop across the coil. This can be prevented by regular and thorough cleaning of the coil.
Vibration can also cause coil failure, especially if the coil is installed near a moving piece of equipment that is not properly isolated. Over time, the vibration can cause leaks in the coil, as the tubesheet holes eventually cut through the tubes. This can be prevented by properly isolating the coil from sources of vibration and regularly inspecting it for signs of damage.
Corrosive environments, both in the air and inside the tubes, can also cause coil failure. This can be combated by using materials that are more resistant to corrosion, such as stainless steel or cupro-nickel, as well as protective coatings.
Finally, freezing temperatures can also cause coil failure, especially if the coil is not properly drained. When ice builds up in the tubes, it can increase the pressure until the tubes rupture, typically at the u-bends. This can be prevented by ensuring that the coil is properly drained and equipped with a functioning damper or freeze-stat.
