Freon is a colorless gas that is also known as R-22. Dupont trademarked the name Freon. CFCs have been used in refrigeration and aerosol cans for many years, but in 1974, a researcher at the University of California hypothesized that CFCs were destroying the ozone layer.

The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, sulfur dioxide, methyl chloride, or propane, that could result in fatal accidents when they leaked. In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12).

The main types of refrigerant gas are CFC, HCFC, HFC, PFC, and blends made from ammonia and carbon dioxide. Refrigerant gas must...

Many modern refrigerants are man-made halogenated gases, especially fluorinated gases and chlorinated gases, that are frequently referred to as Freon (a registered trademark of Chemours). The R number of a chemical refrigerant is assigned systematically according to molecular structure.

The refrigerant gas is a chemical gas which has extremely low evaporation points and is condensed under pressure for chilling the surrounding air. These gases undergo repetitive evaporation and condensation process and as a result, all its heat is pulled out and the temperature inside the unit is chilled out.

Traditionally, fluorocarbons, especially chlorofluorocarbons (CFC’s), were used as refrigerants, but they are being phased out because of their ozone depleting effects. Other common refrigerants used in various applications are ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.

Refrigerants are classified by ASHRAE, and their familiar ‘R’ numbers are assigned according to certain rules. For example, the classification of halogen refrigerants derived from saturated hydrocarbons and consisting of only one substance is illustrated in Fig. 3.3.

Refrigerant contains chemicals called fluorinated hydrocarbons (often referred to by a common brand name, “Freon”). Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut...

Refrigerant is a chemical used in the cooling system of refrigerators. A mechanical refrigeration system depends on storing a certain quantity of refrigerant gas or gases. The device creates controlled chemical reactions by forcing the gas to change state or combining it with other chemicals, drawing heat from the refrigerated compartment.

A refrigerant is a fluid that is used in air conditioners and refrigerators, to take heat from the contents of a refrigerator or the room (in the case of ACs) and throw the heat out in the atmosphere. A refrigerant undergoes phase changes from a liquid to gas (on absorbing heat) and back to liquid (when a compressor compresses it).

The refrigerant is a heat-carrying medium which during their cycle (i.e comparison, condensation, evaporation) in the refrigeration system absorbs heat from allow temperature system and discards the eat so absorbed to higher temperature system. The natural ice and mixture of ice and salt were the first refrigerants.
