Fan coil units are an essential part of HVAC systems, playing a pivotal role in temperature regulation. Let's delve into the workings of these units to understand their importance better.
Components and Operation
A fan coil unit comprises two primary components: a fan and a coil. The operation begins when the fan draws the room's air into the unit. This air then passes over the coils, where heating or cooling occurs based on the temperature of the refrigerant or water flowing through these coils.
Heating Process
In heating mode, hot water from a boiler flows through the coils. As the room's air passes over these heated coils, it absorbs heat and gets warmed up before being circulated back into the room. This process continues until the desired room temperature is achieved.
Cooling Process
When it comes to cooling, chilled water or refrigerant circulates through the coils. The warm room air passing over these cooled coils loses its heat, resulting in cooler air that is then distributed back into the room.
