what is freon and what is it's disadvantage
Answers
Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications.
Disadvantages of Refrigerant R12
1) Low refrigerating effect per pound: The refrigerating effect of R12 per pound of its weight is low compared to the other refrigerants. However, this is not the major disadvantage as it can be used constructively in some cases. In the smaller systems, the greater weight of the R12 helps controlling the refrigeration system in a better way. In the larger systems this disadvantage is offset by the higher vapor density of the refrigerant thus the compressor displacement required per ton of refrigeration with the R12 refrigerant is not much higher than compared with the other refrigerants. The high heat transfer rates in the condenser and the evaporator due to absence of the oil also helps reduce the effects of this disadvantage.
2) R12 is CFC: R12 is the most widely used refrigerant, unfortunately it is the CFC and it has unusually high potential to cause the depletion of the ozone layer. R12 is being replaced by other refrigerants and some of the suggested replacements for R12 are: R-134a, R-401a, R-401b.
