Internal heat exchanger on Evaporator

AI Thread Summary
The discussion focuses on how an internal heat exchanger can increase the evaporating temperature in a single-stage vapor compression refrigeration system, thereby improving the coefficient of performance (COP). Participants seek detailed information on the design and operational principles of heat exchangers, including relevant mathematical calculations. There is a request for published materials or resources that explain these concepts in depth. The conversation emphasizes the importance of understanding the relationship between heat exchangers and refrigeration efficiency. Overall, insights into this topic are highly sought after for practical application in refrigeration 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

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
