Question:
In a refrigerator, the DuPont's Freon (TM) gas which is used for
cooling is getting converted to liquid stage before expansion valve. How
does this happen and at what pressure and what temperature of DuPont's Freon (TM) gas
this happens?
Replies:
"DuPont's Freon (TM)" is the common name for a class of carbon compounds containing
fluorine and other halogens (Cl, Br) and sometimes hydrogen. There are
dozens of various substances. They are liquified by compressing the gas at
a sufficiently low temperature. The refrigeration properties makes use of
the opposite evaporation of liquified freons. Depending upon the
application and the desired temperature one or the other of this class of
compounds is used. You can find a list of properties of some of the types
of freons on the site:
