What is the purpose of the fins on an evaporator?

Evaporator fins are located on the evaporator and as it extracts heat from the air the metal fins help with the thermal energy exchange process that occurs with the surrounding air.

Why is it important to keep evaporator and condenser coils clean?

Keeping the evaporator and condenser coils clean will help protect your AC from an unexpected breakdown. The best way to keep the coils in your HVAC system clean is to schedule regular preventative maintenance.

What purpose does the fins of the condenser coil serve?

The condenser fins are thin metal slats that run along the outline of your exterior AC unit. The purpose of the condenser fins is to move warm air away from the air conditioner while it’s running.

What is the purpose of the evaporator coil in an air conditioning system?

The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.

What do condenser fins do?

The purpose of the fins is to increase the surface area of the condenser, making it easier to pass the refrigerant’s heat to the surrounding air. As the warm, gaseous refrigerant flows through the condenser, heat makes its way from the inside to the outside of the coil.

Can you replace condenser fins?

Repairing or Replacing Damaged Condenser Fins Even though these fins are delicate, they are easy to fix, and it won’t cost a lot. All you need is a condenser fin “comb”. These fins can also be repaired when you have a service performed on your air conditioner.

Why is it important to clean the coils fins?

Why Is It Important to Clean AC Coils? Due to the tight spacing between the coil fins, surface moisture from the cooling process, and the amount of air that flows across them, dirt, dust, debris and other pollutants can build up on the coil surfaces.

Why is coil cleaning important?

Heat gets trapped inside and can’t be effectively released when it is covered with dirt and debris. This will lead to inefficient cooling and increased energy consumption. It is important to have your air conditioner cleaned regularly. Cleaning your AC condenser coil should be a part of it.

How do condenser fins work?

What are coil fins?

The fins on a coil accomplish two major functions: they straighten the air out as it comes in contact with the entering-air side of the coil, and they perform some of the heat transfer. Both are ultra-important to creating the designed heat transfer with balanced air- and water-side resistance.

How long does evaporator coil last?

10 to 15 years
If proper maintenance is regularly performed, then the evaporator coils should last 10 to 15 years, which is the ideal lifetime for an evaporator coil and comparable to the lifespan of an AC unit.

What is the difference between evaporator and condenser coils?

Evaporator and condenser coils handle different sides of the cooling cycle. Let’s walk through the evaporator coil first. An air conditioner’s evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. That is, it’s where the cold air comes from.

What is the function of expansion valve in air conditioner?

As the air conditioner runs, the compressor pulls cold, low-pressure liquid refrigerant through the tubing in the evaporator coil. Before entering the evaporator coil, the refrigerant passes through the expansion valve. This valve relieves pressure from the liquid refrigerant, which rapidly cools it.

Where is the condenser coil located on a refrigerator?

You’ll find your condenser coil within a large, square box with a big fan on top located next to your house. Since the condenser coil’s job is to release the heat from inside your house, it makes sense that the heat would be released into the outside air. As the refrigerant gas travels from the compressor to the condenser coil.

How does dust affect the efficiency of an evaporator?

Even a fine layer of dust on the evaporator coil reduces its efficiency. The dust acts as an insulator, keeping the heat in and the air away from the cold coils. That means the coil can’t absorb as much heat as it can when clean.
