Internal heat exchanger on Evaporator

  1. Aug 13, 2013 #1
    You can read just bold, or all for further info. :D
    The COP for a single stage vapour compression refrigerator increases with an increase in evaporating temperature. I would like to to know how it is achieved in reality with the use of an internal heat exch. on the evaporator.

    Can anyone please send some further information on how to increase the evaporating temperature of a single stage vapour compression refrigeration system by the use of an internal heat exchanger?

    In particular I would like to know the mathematical calculations used when designing to operating principles of the heat exch. in relation to the operating properties of the refrigerator.

    Any knowledge on this would be extremely appreciated. Or any published material that I can read.
    Thank you very much
