In the past years the Chlorofloro Carbons were most commonly used refirigerant. The CFC destroys the ozone layer thus it is replaced by hydroflurocarbons such as R 134a.
The most commonly used refrigrant in the fridges is R 134a which is tetra flouroethane, which does not deplete the ozone layers.
In the automobile Air conditioning the refrigrant R143a is used which is Triflouroethane and for Room A/C's R 22 chlorodiflouromethane is used.
These gases does not require refilling , you have to refill it only when your compressor stops working. The referigrants became weak if the fridge A/C's are not in operation.
For long life of A/C's in the cars the pollen filter should be replaced periodically, and for room A/C's it should be cleaned regularly.

The type of gas being used in refrigeration is dependent on the company. Most of the companies from Europe and US are using R-600a, or isobutane. These are also some of the standard gases in use. And the standard also specifies the quantity to be used.

In case of India and other asian countries, the gas in use is - HFC-134a. This is one of the common gas that doesn't affect the ozone layer. So there are variations of the gases being used in Indian refrigeration companies.

The refrigerators used to have Freon as a refrigerant during the olden days. But, the compound was found to be depleting the Ozone layer. The use has been discontinued now.

Most of the countries - especially the developed countries have now shifted to HFC 134a. This is the commercial name given to the chemical compound 1-1-1-2 Tetraflouroethane.
