13 Feb How Freon Works
Freon is the trade name for the class of chemicals called Chlorofluorocarbons (CFCs). It is used in air conditioning systems as a refrigerant. At room temperature freon is a gas and is a liquid when it is compressed or cooled. Freon gas is fairly odorless, non-flammable and colorless. Some freons have an odor that is similar to ether.
Freons that are commercially available include the following:
R22 Chlorodiofluoromethane (used for air conditioners)
R134A – Tetrafluoroethane (used for cars)
R410A – This is a replacement or alternate for
R22 given the worldwide phaseout of R22 after it was shown that it depletes the Ozone Layer.
The major components of any air conditioning systems are an expansion valve, two coil sets with refrigerant in them (usually Freon), and a compressor, that are connected together. Freon takes on gas and liquid forms, and it works in this cycle:
First of all, Freon gas enters into the compressor. The Freon is then heated by the compression process which changes the Freon into a high-pressure gas.
Hot Freon gas then gets released inside of the first coil. This high pressure results in the gas moving along the coil, which is on the exterior of the building. As the Freon gas travels along, it starts to cool down as the system’s fan causes the heat to be absorbed by the outside air. This cooled Freon gas is then converted into a cool liquid form of Freon.
This cool liquid form of Freon then enters into the expansion valve. It is converted into cool Freon gas again and then gets released inside of the second coil. This second coil is located on the inside part of the building.
A fan that is next to the second coil blows the air from inside of the building. The second coil has the cooled Freon gas inside of it. The heat in the air is absorbed by the Freon gas, which causes the air to cool. Then the Freon gas starts heating it up again. The air that has just been cooled gets released into the inside part of the building. This process continues to repeat itself with Freon gas once again entering the compressor.
It is recommended that the coolant level inside of your air conditioning system be checked at least once per year. A system that is just 10% low on coolant does not operate as efficiently as it could and may cost you more than 20% extra on your monthly utility bills. If your air conditioning system continues to run with low coolant levels it can damage your compressor.
Freon Health Effects
Freon does not appear to have serious long-term health effects. It isn’t a mutagen or carcinogen and doesn’t damage the liver. There are limited irritation effects. It is mainly a simple asphyxiant that at very high concentrations can cause suffocation and dizziness. Individuals with heart problems are the people who are most at risk given that it has been shown that in high concentrations it can cause heart palpitations and irregular heartbeats.To know more about us visit the website at http://www.bluonenergy.com/freon-replacement/.
