What is a Coil?

Coils in HVAC Systems

In Heating, Ventilation, and Air Conditioning (HVAC) systems, coils are critical components that play a vital role in transferring heat energy from one location to another within the building. By absorbing heat from the indoor air and releasing it outdoors or into the surrounding environment, coils help to distribute warmth throughout the space. Coils typically consist of two main components: a base coil (also known as the radiator) where water flows through and absorbs heat, and an expansion/contraction coil (or expansion valve) where refrigerant expands and contracts, allowing for efficient heat transfer. The performance of coils can be significantly impacted by factors such as temperature, humidity, and air flow rate, making them a critical component in HVAC systems that require precise control over temperature and humidity levels to operate efficiently.
