Properties of Refrigerants

Updated on April 12, 2010

Desirable Properties of a Primary Refrigerant

  1. The liquid has to vaporise at the evaporator coil to cause cooling. The liquid at the evaporator coil should therefore vaporise easily, otherwise the compressor will have to create too much of vacuum to cause the liquid to vaporise. Thus, 'Boiling Point' of the refrigerant should be low.
  2. Pressure to which compressor has to compress the drawn gases, to convert them back into liquid at the condenser, should be low. Therefore the refrigerant vapors should be easily condensible.
  3. Every kilogram of liquid refrigerant vaporised at the evaporator coil should take away a large amount of heat, i.e. 'Specific Enthalpy of Vaporisation' (latent heat) of refrigerant should be high. Otherwise mass flow rate will be high.
  4. Once the evaporated gas is compressed, the temperature of seawater should be low enough (below critical temperature of the refrigerant) to be able to condense these gases to liquid form. Thus 'Critical Temperature' of the refrigerant should be high.
  5. Vapor produced after vaporisation of the liquid at the evaporator coil should occupy minimum volume, to keep pipeline diameter, compressor size, etc. small and compact. Thus refrigerant vapor should have low 'Specific Volume'.
  6. Non-Corrosive
  7. Stable
  8. Non-flammable and Non-explosive
  9. Compatible with crank case oil, oil seals, gaskets, metal involved, etc.
  10. Easy leak detection possible
  11. Non-Toxic
  12. Environmental friendly
  13. Cheap
  14. Easily available
  15. Easily stored.

      Very interesting hub. I have never really thought about the process that has to occur in order for the fridge to cool properly, but it's "cool" LOL to learn something new. Thanks for sharing.

      Very interesting - I didn't know this was how it worked! I think it's great that you have so many of these Hubs on these technical topics people are interested in.
