- 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. |
