What is refrigerant and its types?

Chlorofluorocarbons are refrigerants that contain chlorine. They have been banned since the beginning of the 90’s because of their negative environmental impacts. Examples of CFCs are R11, R12 and R115. The conversion of equipment and systems using CFCs has not yet been completed.

How many types of refrigerants are there?

However, there isn’t just one type of refrigerant, which makes it easy to get them confused. There are actually three different types, and using the wrong one can damage your air conditioner because they’re not interchangeable.

What is a class A1 refrigerant?

Refrigerants are classified as below: The vast majority of HFC and HFC/HFO blend refrigerants in current use are classified as A1, with low toxicity and zero flammability. Ammonia, which has been in use for many years, is classified as B2L; R-152a is an A2 refrigerant, and all hydrocarbons are classified as A3.

What safety classification is R22?

Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure.

What are the four types of refrigerant?

Here are the different types of refrigeration systems:
  • Evaporative Cooling. Evaporative cooling units are also referred to as swamp coolers. …
  • Mechanical-Compression Refrigeration Systems. Mechanical compression is used in commercial and industrial refrigeration, as well as air conditioning. …
  • Absorption. …
  • Thermoelectric.

What is the most common refrigerant?

hydrofluorocarbons (HFCs)
The most common type of refrigerants used today across the world are hydrofluorocarbons (HFCs). Previously, chlorofluorocarbons (CFCs) were more widely used, but were phased out following the introduction of the Montreal Protocol in 1987.

What is R-32 refrigerant?

R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

What is 12A refrigerant?

12A Refrigerant is designed as a replacement for ozone depleting R-12 and R-134A refrigerant. 12A Refrigerant is hydrocarbon based is non-toxic and non ozone depleting Contains 4 x 6oz cans.

What is 410A refrigerant?

R-410A is a chlorine-free refrigerant that meets the U.S. EPA’s newest, most stringent environmental guidelines. R-410A was developed as an alternative to R-22 (Freon), which will be phased out over the coming years in response to international environmental concerns.

Which refrigerant is used in AC?

What type of refrigerant is used in air conditioning systems? There are many different types of refrigerant used in a variety of refrigeration products, but for air conditioning systems, there are two main types; R-22 or more commonly known as Freon, and R410A, also known as Puron.

Is R22 a CFC or HCFC?

HCFC refrigerant
R-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth’s protective ozone layer, the United States is phasing out R-22, along with other chemicals.

What is R-32 refrigerant?

R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

What refrigerants are used now?

The most popular hydrofluorocarbon (HFC) refrigerants for new commercial air conditioning systems in the US today include R-410A, R-407C, and R-134a, but there are still plenty of R22 systems out there.

Which CFC is used in refrigerator?

It is called dichloro difluoro methane. It is chloro fluoro carbon (CFC) used in refrigerator.

What is difference between CFC and HFC?

Because they contain hydrogen, HCFCs break down more easily in the atmosphere than do CFCs. Therefore, HCFCs have less ozone depletion potential, in addition to less global-warming potential. HFCs do not contain chlorine and do not contribute to destruction of stratospheric ozone.

Why R134a is used as refrigerant?

Also, R-134a is a very safe refrigerant with an ASHRAE safety classification of A1. This means it is not flammable and has very low toxicity levels. Because HFC-134a has no chlorine in its molecule, it has a zero ozone-depletion potential (ODP) and doesn’t deplete the stratospheric ozone layer.

Why CFC is used in AC?

They have an exceptionally high heat capacity which makes them effective in the refrigeration process. CFCs were chosen in the 1920s and 30s to replace other chemical refrigerants toxic to humans like ammonia and methyl chloride.

Which gas is used in refrigerator?

-Tetrafluoroethane
Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, unlike Freon. R-134a is becoming much rarer in Europe. Newer refrigerants are being used instead.
