Air Conditioning Coils Explained

It might be very hard to differentiate between the different types of coils used in conditioning systems. This might be because most of the coils carry out the same function which is to remove heat and make the surrounding air cooler. The coils might have some similarity in functioning but they are all made for specific purposes.

Condenser coils: The purpose of this coil is to condense refrigerants before they are evaporated in an evaporator coil. It is made up of tubes which are filled with the refrigerant in order to allow the coils to carry out the condensation process. The refrigerant is hot when place in the condenser. Therefore, this coil also performs an added action which is cooling the refrigerant before it changes from liquid to gas.

Evaporator coils: This coil’s function is to remove heat as warm air passes through the pipe-like structures that make up the coil. One warm air enters into the coil; the coil removes it and sends the air out into the room very cool. This is what makes the room cool when using an air conditioner. However, there are three different types of evaporator coils.

These three coils ensure maximum functioning of the system by working together. They include:

  • Vertical evaporator coil: This is mainly involved in cooling air that enters the system in either upward or downward direction. It does this by condensing the air in order to retrieve some moisture from the air and expel it with a bid to make the surrounding air less humid. This creates cooler air in the homes since moisture not removed could hold on to some heat.
  • Cased evaporator coils: This functions in similar way with the vertical evaporator coil. The major difference is that it possesses an outer covering and it uses a coolant to separate the warm air from the cool air enabling only cool air to flow into the room via ducts.
  • Uncased evaporator coil: These are unique because they can be altered to fit in any device to enable cooling in homes. They are mostly preferred due to this flexibility in shape.

In general, it is important to know that all coils have different functions that are made possible by they way they are structured. The only thing that makes them similar is the fact that they all ensure your conditioning system cools your
