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.

4. Application of CFC’s

5. Properties of CFC’s
CFC

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
