Evaporator Coils vs. Condenser Coils

What is a coil in an air conditioner?

off, let’s answer the question “What is an evaporator coil in an air conditioner?” In an air conditioning system, a coil refers to a component that plays a crucial role in the cooling process of your home. The coils in AC systems are typically made of copper or aluminum. These materials offer excellent heat transfer properties and durability, making them suitable for a coil’s function. Air conditioning systems typically have two types of coils: the evaporator coil and the condensing coil.

What is an evaporator coil?

Now let’s answer the question “What is an evaporator coil?” The evaporator coil is located inside the indoor unit of an air conditioning system. The coil contains a network of tubes that are often made of copper or aluminum and are responsible for absorbing the heat from indoor air. As the refrigerant passes through the evaporator coil, it undergoes a phase change from a liquid to a gas. This process absorbs heat from the surrounding air, thereby cooling it down. The cooled air is then circulated back into the room.

What is a condenser coil?

Now let’s explain “What is a condenser coil?” The condenser coil is in the outdoor unit of an air conditioning system. Its primary function is to release the heat that was absorbed by the evaporator coil. The condenser coil consists of a network of tubes, like the evaporator coil. When the refrigerant, now in a hot gaseous state, flows through the condenser coil, it releases the absorbed heat to the outside environment. This heat transfer process causes the refrigerant to condense back into a liquid form. The condensed refrigerant is then pumped back to the evaporator coil to repeat the cooling cycle.

How Do the Evaporator Coil and Condenser Coil Work Together?

Refrigerant enters the evaporator coil from through copper tubing that is connected to your outdoor unit. Once inside, it absorbs the heat from the air blowing over it. Moisture in the air is condensed into water on the coils, which then empties into the drain pan. Removing this moisture lowers the temperature of the air blown into your home, creating a more comfortable environment.

The now-warm refrigerant flows to the outdoor unit. The refrigerant then runs through the condenser coil, where the heat is expelled to the outdoor air. The refrigerant then travels back inside to the evaporator coil to repeat the process.
