Internal heat exchanger on Evaporator

Click For Summary
SUMMARY

The discussion focuses on the impact of internal heat exchangers on the evaporator in single-stage vapor compression refrigeration systems. It establishes that increasing the evaporating temperature enhances the Coefficient of Performance (COP) of the system. Participants seek detailed mathematical calculations and design principles related to internal heat exchangers, emphasizing their role in optimizing refrigeration efficiency. The conversation highlights the need for published materials and practical insights into the operational properties of these systems.

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
