The Main Difference Between The Condenser Coil And The Evaporator Coil In Your AC

If you didn’t already know, there’s more to it than just the difference in location between the condenser coil and the evaporator in your air conditioner. In the case where your air conditioner fails to meet the levels of comfort that you need, it is often determined that something has malfunctioned. Most of the time, it’s often thought of as the coolness generator malfunctioning.

However, it should be noted that a coolness generator doesn’t exist and this issue can be ruled out on the spot. Air conditioners simply move heat and don’t make coolness so the coolness that you feel is simply coming from a transfer of heat in one of the most effective ways possible. The main functional difference between the condenser coil and the evaporator is the forces and the principal being used to move it from one space to another.

The first air conditioner was patented in 1906 by Willis Carrier and it defined it as the air conditioner and not the air cooler. In essence, the concept behind this idea was not to cool the interior of the printing factory but rather to reduce the humidity. Reducing the humidity in the printing factory would simply mean that there was better printing quality.

The method that he applied simply condensed the humidity in the building and also removed the heat. Hence, a cooler building is what happened because of his idea and his device. In today’s society, the mechanical process applied to extractors is removing the heat to the outdoor location while leaving a cooler indoor setting.

The condenser coils and the evaporator are better known as system components that tend to perform heavy lifting during heat transfer. However, they function in the opposite way. Find out more about the type of aircon coils.

A Concise Trip Around The Loop

A closed-loop refrigerant system is one of the main systems found in your typical residential air conditioner split system. If you didn’t already know, the refrigerant can be considered as being the lifeblood of the system since it continuously circulates between the condenser and the evaporator. Refrigerant is a specially designed chemical that is a relatively high heat-absorbing property. Due to this characteristic, it can easily change state when subjected to pressure.

The Evaporator Coil

When heat is removed from within your home or business area, the refrigerant is added to it. This process is known as the main function of the evaporator coil. The evaporator coil is installed on the air handler on the inside and the evaporator is constantly being exposed to a flow of heated air.

The heated air is pulled from each room of the house where it is then returned to the air ducts. As the refrigerant is circulated through the copper tubing within the coil, it usually runs at 40 degrees in the form of cold vapour. When the refrigerant is in this state, the properties to absorb heat is definitely maximized.

As the energy from the warm area is transferred through the freshly chilled copper coiled tubing it is easily absorbed by the flow of refrigerant. After the coil extracts the heat energy, the blower then pushes cooled air into the air ducts which are then distributed throughout the entire space. During the heat extraction process, warm air makes contact with the surface of the evaporator coils in an effort to trigger condensation.

When this occurs, the humidity levels are lowered during airflow. Hence, the conditioning process of the air is the same as it was all those years ago when Willis Carrier implemented his idea. After the air leaves the coil, the refrigerant flows through the conduit and into the air conditioner’s outdoor contraption. This outdoor component can be easily found behind your house or building.

The cabinet that you see there tends to contain the condenser coil and the compressor. Any refrigerant that enters the compressor is usually pressurized and contains heat energy molecules along with those from the rise in temperature. However, this usually applies when the vapour temperature exceeds 100 degrees. In such a super-heated state, there is an efficient energy transfer of heat to the outdoors; this occurs even when the temperatures are soaring on extremely hot days.

The Condenser Coil

The condenser coil is very similar in its design to the evaporator coil. However, the main difference between the both is that they’re basically the opposite of each other. So when your evaporator coil takes heat from inside the condenser pushes it to the outside of your home.

The heat energy removed from within your home is then compressed into hot vapour and it is then quickly released as the refrigerant circulates. During this circulation period, the refrigerant condenses into its liquid form. When the refrigerant releases heat, the fan within your air conditioner unit simply blows the air through the condenser coil and further disperses the heat to the outside of your home or business.

As the high pressurized refrigerant leaves the condenser coil, it simply makes a u-turn and runs back to the evaporator coil. There is also the inclusion of an expansion valve that reduces and restricts the flow of refrigerant. This simply forces it through a very narrow orifice where it is then converted into a vaporized state. At this point, it is once again ready to once again absorb the heat from within your home.


The condenser and the evaporator of your air conditioner are like two peas in a pod. They work in harmony as they take the heat out and push cooled air into your home. There’s more to them than just their location.
