  • Refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. The two main uses of refrigerants are refrigerators/freezers and air conditioners.
  • The ideal refrigerant has good thermodynamic properties, is noncorrosive, and safe. The desired thermodynamic properties are a boiling point somewhat below the target temperature, a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form, and a high critical temperature.
  • A good refrigerant, has to live up to a few requirements. Obviously, we want something that is nontoxi and unreactive. The refrigerant has to be stable for the lifetime of the refrigerator, ozone-safe, having a low boiling point but not too low, because when a refrigerator is running, the refrigerant is constantly being boiled from a liquid to a gas, and then being condensed back into a liquid again. If the boiling point is too low, it will be hard to condense back into a liquid.
  • CFCs boil at just the right temperature, and this along with the fact that they weren't poisonous made them very attractive at first as refrigerants. Fortunately, HFCs can be used to replace CFCs as refrigerants and won't damage ozone.
  • The absorption cycle is a process by which refrigeration effect is produced through the use of two fluids and some quantity of heat input, rather than electrical input as in the vapor compression cycle.
    Many factors are considered to choose a refrigerant.They are ozone depletion potential, global warming potential, combustibility, thermal factors.
  • In Cascade Refrigeration System, the refrigerants can be selected to have reasonable evaporator and condenser pressures in the two or more temperature ranges.
  • In Absorption Refrigeration System refrigerator the working fluid is pumped as a liquid the specific volume is less than that of a gas , the work input is much less, there are considerable savings in power input because a pump is used instead of a compressor, this is weighed off against the cost of extra hardware in an absorption system.
  • Refrigerant R290, or propane, is a possible replacement for other refrigerants, which have high impact on environment, in small hermetic systems, like factory made commercial refrigerators and freezers. It has zero ozone depletion potential ODP and a neglectible global warming potential GWP. Furthermore it is a substance which is a part of petrol gases from natural sources.
  • Refigeration mixtures are used for space thermal management.
    Hydrocarbons are flammable and, if due diligence is not observed, safety could easily be compromised. Only engineers who are competent to use these gases should be allowed access to them to ensure that the good name of the refrigeration and air conditioning industry is maintained.
  • Hydrocarbon refrigerants possess full chemical compatibility with nearly all lubricants commonly used within refrigeration systems.
  • Absorption and adsorption cooling systems, which quite often are fuel-fired, are a practical means of providing both commercial and industrial cooling without imposing a major drain on a developing electric infrastructure and therefore a major drain on the limited developmental capital available to most developing countries.
  • Solar refrigeration is technology that should be given priority when choosing sustainable development options in developing countries .
    Trigeneration has considerable benefits from an energy standpoint.
