Evaporator Coils and How They Function in Air Conditioning Equipment

Evaporator Coils and How They Function in Air Conditioning Equipment Knowing the basic facts and terms about your air conditioning system is a must. But, nothing is more important than learning how the components work particularly the evaporator or the indoor unit. If your A/C unit is still a mystery to you, it is necessary that you learn these simple technical terms and processes in the evaporator coils. Evaporator Coil: What Is It? Also known as the evaporator core, the evaporator coil is an essential A/C component where the refrigerant absorbs warm air then converts it to cool air. Commonly, evaporator coils comprise of steel, aluminum, and copper in the making because these metals easily conduct heat. The coils come either in U shapes or panels. Home Cooling Procedure Through the Evaporator Coils If you think that your air conditioner produces heat just like the way your furnace does, you are mistaken! Your A/C unit uses refrigerant to complete the cooling process by absorbing heat from indoors and releasing it outside. Along with the condenser, ductwork and air handler, your A/C’s evaporator coils work to distribute conditioned air evenly throughout the house. The pipes absorb the heat while the air passes through it. The liquid refrigerant is converted into gas as it travels in the pipes. Once it reached the evaporator, the pressure lessens, and the heat content dissipates. As the process continues, the refrigerant vaporizes while absorbing all heat content in the air. Finally, the vaporized heat in the form of a low-pressure gas moves to the lowest part of the compressor. Then, the entire refrigeration process repeats. The Role of Evaporator Coils The air that passes through the evaporator coils is meant to be converted into cool air. When the place achieves the desired temperature, the refrigerant turns off automatically. The moment it signals warm air, the refrigeration process will start over again. When your air conditioning unit is working at its best condition, the evaporator coils stay at a dew point or in a slightly cool state. Its present state causes the vapor to undergo condensation out of the processed air. Lastly, the moisture is drained out of the system to allow the cool air to circulate throughout your home. Do you experience uneven cooling at home? Something might be wrong with your evaporator and the other components of your A/C unit.
