How does the evaporator work in an air conditioner?
The evaporator removes heat from the area that is to be cooled. The desired temperature of cooling of the area will determine if refrigeration or air conditioning is desired. For example, food preservation generally requires low refrigeration temperatures, ranging from 40°F (4°C) to below 0°F (-18°C).
What kind of temperature does an evaporator need?
For example, food preservation generally requires low refrigeration temperatures, ranging from 40°F (4°C) to below 0°F (-18°C). A higher temperature is required for human comfort. A larger area is cooled, which requires that large volumes of air be passed through the evaporator coil for heat exchange.
What happens when an evaporator coil is not working?
Failure to do so can damage the compressor. The evaporator coil’s job is to absorb the heat from the air within your house. During normal operation, condensation collects on the coils and evaporates. However, if something isn’t working correctly during the cooling process the condensation could freeze.
What happens when refrigerant is changed in an evaporator?
Changing the state of the refrigerant in the evaporator coils is as important as the air flow over the coils. Liquid refrigerant supplied to the coils by the expansion valve expands to a vapor as it absorbs heat from the air.
Why does my evaporator need to be replaced?
The main reason that an evaporator coil would fail and need to be replaced is due to erosion. Over time, the refrigerant flowing through the evaporator’s coils wears down the inner lining, making the coils weaker. Certain evaporator coil cleaners can also corrode and weaken the outer lining of the coils.
How can I tell if my AC evaporator is damaged?
Like most AC issues, the first indicator of a damaged AC evaporator is poor performance. Since the AC evaporator is the major part that removes heat from the air, failure is rather simple to determine. However, there are 4 other warning signs of a damaged AC evaporator: 1. The cool air is weak or no cold air is blowing at all.
How long does an AC evaporator coil last?
Air conditioners last anywhere from 10 to 12 years. That said, if your AC is nearing 8 years old, replacing just the evaporator coil would be like putting a brand new engine into a dying car—it’s just not worth the money.
