The job of refrigerants 

The refrigerant gas is the most essential piece of a cooling framework. Most ACs chip away at the standards of pressure and development of the refrigerant. The gas turns out to be exceptionally hot when it is packed. At that point, it is showered on to the dividers of the warmth exchanger. R-12 is the essential refrigerant utilized in cooling. As of late, however, it is being eliminated for the R-34a.
