Why are chilled water coils important to climate-controlled buildings

When it comes to large commercially and municipally used buildings, chilled water coils are of extreme significance. These are essential components of air handling units that help to extract heat from the indoor environments and control the room temperature. While energy efficiency and high indoor air quality are more important than ever, chilled water coils are at the forefront of one of the largest systems in HVAC.

Type of coil cools by having cold water (usually from a central chiller) flow through the coils (copper or aluminum tubing with a fluted fin design). The heat is removed and taken away by the chilled water between the coil and the airstream. This has the effect of lowering the interior temperature and dehumidifying, which creates a cooler and more comfortable, healthful indoor environment.

However, the primary advantage of chilled water coils in an HVAC design is the versatility they provide. These coils can be configured to satisfy different load requirements, weather conditions and zoning effects. As a consequence, they are widely used in systems that must provide high-quality air and that cannot afford to shut down, such as facilities with computer rooms, hospitals, large office buildings, and universities, where continuous performance is required.

But system efficiency depends on coils being maintained. Accretion of dust, debris and biofilm can inhibit the flow and the thermal transfer efficiency. This puts excess strain on the system and wastes energy. Regular inspection and professional cleaning will help maintain the efficient operation of the chilled water coil.

Purchasing top-quality chilled water coils that are custom-built to your system’s particular needs can also help to save you money in the long run on your operational costs. Be it new construction or system retrofit, coil efficiency is a key player in the entire performance of an HVAC system.

When all is said and done, chilled water coils are the silent heroes in reliable, energy-efficient cooling in tough commercial applications.
