Have you ever wondered why coolant is used in an AC unit? Understanding the issue requires a closer look at how HVAC systems work. When you turn on your air conditioner, the process of cooling your air begins.
The coolant, also known as refrigerant, plays a crucial role in this process. It acts as a medium that facilitates heat exchange, allowing the AC unit to produce cool air. Here’s how it works: as warm air passes over the evaporator coil, the coolant absorbs the heat and transforms from a liquid to a gas.
The compressor then compresses the gas, raising its pressure and temperature. Next, the hot gas travels to the condenser coil, where it releases the absorbed heat into the surrounding environment. Finally, the refrigerant condenses back into a liquid and returns to the evaporator coil to repeat the process.
Freon is a popular type of refrigerant used in AC units. However, it is essential to keep an eye out for refrigerant leaks, as they not only affect the efficiency of your AC unit but also have a harmful environmental impact. So next time you enjoy the cool air from your AC, remember that coolant plays a vital role in the process.
