The Importance of Maintaning Heat Transfer Coils

Condensed chiller

Regular coil inspection and cleaning are crucial to keeping your air conditioning performance at its highest capacity and improving your building’s energy efficiency. An HVAC is a complex system that features heat exchanger coil which helps to replace heated air with cool air. Heat transfer coils, as the name implies, distributes heat within the HVAC refrigerant.

Common Coil Problems
There are different kinds of exchanger coils in today’s HVAC units, but they pretty much perform the same function. Examples include condenser coils, hot water coils, booster coils, cold water coils, evaporator and steam coils. One of the most common problems with heat transfer coils, particularly the condenser coil which is subjected to unfiltered external air is dirt.

The air contains leaves, dust, pollen, seeds and other contaminants which makes the compressor to work twice as much, consuming a lot of energy and increasing utility costs. It also reduces the HVAC efficiency in regulating temperature thus affecting your comfort. When dirt gets stuck to the fins of the cooling coil, it will over time form a stubborn coating that corrodes the coil and impede efficient heat transfer. Other issues that can affect HVAC heat transfer coils include condensation, improper insulation, and freezing temperatures.

How to Protect Your Coils
Generally, HVAC units will run as expected, but to ensure your system operates efficiently some maintenance procedures must be considered. Perhaps the first thing to do when exchanger coil is etched with dirt is to remove the contaminants to avoid further corrosion. However, if the coil has been eaten up completely due to long exposure to the contaminants, consider replacing the cooling coil, which is quite costly than coil maintenance.

Condensation is a common problem with evaporators coils, which causes it to rust. To reduce the effects of oxidation as air is chilled through your heat transfer coils, speciality coating is recommended. A layer of coat will minimize corrosion, boost efficiency and increase the operating life of your condensed chillers.

Lastly, to protect your heat exchange coils against inclement weather conditions you may want to consider extensive insulation. This will protect your coils against hot summer days and freezing winter nights. Regular coil inspection and effective maintenance will reduce your overall energy utility bill and ensures efficient heat transfer to keep you comfortable.
