The Basics Of A Baldwin Park AC Unit

Baldwin Park AC Unit,

Most people don’t know anything when it comes to AC units. So today we are taking you back to the basics to learn all the terms used in the AC world. Hopefully, this doesn’t confuse you and you can gain a grasp of how your  Baldwin Park AC unit works.

To start, there are two most common types of AC units: room & central. Room units work best in a small space or just one room. Central units circulate cool air with supply and return ducts. Although, if you want a combination of both of these systems, then a ductless, mini-split system is the best option. These are similar to a central unit in that they have an outdoor compressor and indoor handling unit.

Next, we’ll explain the five parts of an AC Unit.

  1. Refrigerant
  2. Compressor
  3. Condenser
  4. Expansion Valve
  5. Evaporator Coil

The Refrigerant changes liquid into a gas vapor and collects heat. The flow of refrigerant is controlled so that extra heat is added above the saturation temperature. Next, the Compressor pumps and pressurizes refrigeration in order to turn it back into liquid.

The Condenser Coils work outdoors and cool hot vapor by blowing air over finned condensing coils. It uses a network of tubes filled with a refrigerant that removes heat from the heated gas refrigerant causing excess heat to escape into the outside air. The condenser works the opposite of the evaporator and changes the evaporated refrigerant back into a liquid through a process known as “heat transfer”.

In between the evaporator and condenser coils is the expansion valve, which works the hardest by forcing gas to expand and cool. It also regulates refrigerant flow into the evaporator. So the compressor supports the condenser, while the expansion valve helps the evaporator.

Once the air is cooled in the expansion valve it moves into the Evaporator Coil where it receives the liquid refrigerant. The Evaporator coil works indoors and consists of a network of tubes filled with a refrigerant that removes heat and moisture from the air as the refrigerant evaporates into a gas again. The evaporator receives the liquid refrigerant and converts it to gas through a drop in pressure. Here, hot air blows across coils and heats it, while coils carrying cold gas blows back into the home. From here, the cycle continues.
