Air Conditioning Guide: What Is Refrigerant?

The modern air conditioner requires numerous components to make it work: blowers, motors, a compressor, coils. But all of these together would create nothing more than an oversized fan if not for the presence of refrigerant running through the lines of the air conditioner. Refrigerant is the life-blood of an AC necessary for the process of heat exchange that cools down the inside of a building.

Like all the parts of an air conditioner, refrigerant is something that must remain in the hands of professionals. If you encounter a loss of refrigerant in your AC, call for experts to handle the problem.

The details of refrigerant

Refrigerant is a chemical blend that can easily shift from liquid to gaseous state and back again. Refrigerant begins in an air conditioner’s compressor, where the action of the compressor changes it into a high-pressure, high temperature gas. The refrigerant then travels to the outdoor coil, where it releases heat to the outside through condensation. It then moves to the inside cabinet, passing through an expansion valve that lowers its pressure and further reduces it temperature so that it shifts back into liquid form. The cooled refrigerant then moves through the indoor coil, where it absorbs heat through evaporation, cooling down the air. The refrigerant finally returns to the compressor to begin the cycle over.

Today, the refrigerant found in most home air conditioning systems is a blend called R-410A, a non-ozone depleting chemical mixture designed to replace an earlier blend, R-22. There have been many different types of refrigerants over the years. The earliest were toxic, combustible, or acidic, and it wasn’t until the invention of the first safe refrigerant, which was given the trademarked name “Freon,” that air conditioners started to enter use in homes. Continual advances in the production of refrigerant have resulted in increased air conditioner efficiency.

Refrigerant loss

During the heat exchange cycle of condensation-evaporation, refrigerant does not dissipate. It remains at the same level—called its “charge”—throughout the air conditioner’s life, unless a leak occurs. Leaking refrigerant will threaten an AC’s ability to cool and could lead to damage to the compressor due to overheating.

Should you notice a drop in cooling, ice appearing along the indoor coil, or strange hissing sounds from your AC, the system may be losing refrigerant. You will need professionals to locate the leak, seal it, and then recharge the system with the proper blend of refrigerant.
