How does an evaporator coil work?
Your evaporator coil removes heat from the air. What most people don’t realize is that AC’s don’t actually create cool air. They simply remove heat from the indoor air, which is where your evaporator coil comes in. The evaporator coils are filled with very cold refrigerant (a heat transfer fluid). And as warm air from inside your home passes ...
What happens when warm air passes over a refrigerant coil?
And as warm air from inside your home passes over those cold coils, the refrigerant absorbs all of the heat and moisture from that air. The result? Cold, dehumidified air that gets blown directly into your home. Warm “return air” from the home passes over the evaporator and becomes cool “supply air”.
Why does my AC compressor freeze?
Because of the super low temperature of the refrigerant, your evaporator coils need a healthy flow of warm air to prevent them from freezing over . But if they don’t get enough airflow , they will freeze over, limiting your AC’s ability to cool the air. The worst part is that if the problem isn’t fixed, it can eventually destroy your AC’s compressor, which can be a pricey repair.

How does the air in a refrigerant work?
The ambient air gives up its heat to the refrigerant as it passes ever the evaporator. The refrigerant then vapourises as it absorbs the heat lost by the air whilst the air itself is simultaneously cooled.
How does refrigerant vapourize?
So as it moves along the evaporator, the refrigerant vapourises by absorbing heat from the air. So more and more vapour is produced and less liquid is present. At point H, the last droplets of liquid vapourise. This point then is right at the end of the evaporation step, and there is fully 100% vapour present at 5 °C.
What is the pressure of a refrigerant at H?
At H, the refrigerant exists as 100% vapour at a pressure of 4.8 bar. The air in the room is a lot warmer than the vapour and is still passing over the evaporator, so the temperature of the vapour continues to increase until we reach point I.
Why is the refrigerant in a counter current flow?
You’ll notice that the refrigerant and the air are in counter-current flow in the evaporator in order to optimise the exchange of heat.
What is the temperature difference between the evaporator and the air inlet?
This difference is known as ΔT total for the evaporator. It is generally somewhere between 16 and 20°C In our example, ΔTtotal is 23 – 5 = 18°C.
Where is the point G on a compressor?
Point G is situated right in the middle of the evaporator, where the R22 is at its evaporation step. A thermometer at G would read 5°C, that is the same temperature indicated by the LP gauge located at the suction side of the compressor.
What is the coil on a split system air conditioner?

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. Over time, this buildup reduces the system’s ability to transfer heat into and out of the home, thus reducing your system’s ability to provide summer cooling. In more extreme cases, dirty coils can also hinder or block the airflow that is so important to the entire process. This can result in having a less comfortable home and rising utility bills due to the lost energy efficiency. Even worse, dirty coils make the system work harder than intended and can result in shorter system life and potentially expensive repair bills. In short, the cleaner the air conditioning coil, the more efficient the system will operate.
