What is freon used for

The entire process depends on a special liquid that is pumped through your HVAC unit and carries the higher or lower temperatures where you need them. It is a mixture of different chemical gases that easily become liquid when put under high pressure. Your air conditioning compressor does this job, continually bringing about a phase change in the coolant.

The cooled, compressed liquid is pushed through the evaporator coils of the unit where it absorbs heat as it evaporates back into a liquid.

However, Freon is used as a refrigerant in upright and chest freezers. Some dehumidifiers, food transport vehicles, and industrial food storage freezers use Freon as well. This agreement is known as the Montreal Protocol and was one of the biggest topics of climate change at that time. By January 1, , the US has agreed to have cut down to What does this mean for those who still require R? This does not mean that R will not be available, it will just be much harder to find and will most likely be more expensive.

In an HVAC system, this is done by pushing the refrigerant through a closed loop of copper or aluminum coils. There are other components involved in the system, and they include a condenser, evaporator, compressor, and a special valve TX valve that affects the state and temperature of the refrigerant.

At higher temperatures, the refrigerant releases heat to the surrounding environment, and at its lowest temperatures, it removes heat from the surrounding environment. While refrigerants are most notable for being used in air-conditioning systems for building, they also have other applications aside from that. Refrigerant is also used in facilities that require controlled environments, like medical facilities or laboratories.

Considering the wide array of applications, one can surmise that HVAC technicians are a crucial aspect to maintaining the proper working conditions of facilities and equipment where refrigerant is used. One way a technician does this is by testing the pressure of the system to determine if there are any leaks or other issues.

In most cases, low refrigerant levels can cause pressure drops. Due to certain chemical properties and issues with safety, some have been discontinued, while others are used in different systems based on these properties.

A small amount of oil is combined with the Freon gas to lubricate the compressor. When the Freon gas is compressed, its pressure rises, making it very hot. Next, the hot Freon gas moves through a series of coils, which has the effect of lowering its heat and converting it to liquid. The Freon liquid then flows through an expansion valve, which causes it to cool down until it evaporates. The result is low-pressure Freon gas. The cold gas is then channeled through another set of coils. This allows the gas to absorb heat and lower the air inside the room or building.

Your air conditioner filters the air in the room and cleans out dust, pollen, smoke and other kinds of dirt, pollutants and allergens.
