The document discusses the properties and applications of CFCs and HCFCs as refrigerants. CFCs, known as Freons, have high ozone depletion potential (ODP) and global warming potential (GWP), while HCFCs have lower ODP and GWP values but still impact the environment. Examples and specific characteristics, such as boiling points and critical temperatures, are provided for both types of refrigerants.

CFC’s and HCFC’s :Properties and
Application

2. Refrigerant
 “ Refrigerant acts as a transportation
medium to move heat absorbed in the
evaporator to the condenser where it is
rejected ”.

3. Synthetic Refrigerants
1. CFC’s:-
 Combination of
CARBON+CHLORINE+FLUORINE therefore
commonly know as FREONS.
 High ODP=1 and High GWP.
 CHLORINE has an excellent anti-wear
characteristic.
 Few examples are: R-11, R-12, R-13 and etc.

6. Synthetic Refrigerants
2. HCFC’s:-
 Combination of HYDROGEN+CHLORINE+FLUORINE+
CARBON.
 Low CHLORINE content than CFCs.
 It has ODP=0.05 & LESS but not zero.
 Low GWP value than CFCs.
 NON-FLAMMABLE & environment acceptable.
 Few examples are:
R-123, ODP=0.02, BP= -28’C, Critical Temperature=183.68’C
R-22, ODP=0.05, BP= -40.81’C, Critical Temperature=96.15’C
