Hello all,

I've been wondering about the performance data given by :
Bitzer transcritical compressor

In the performance data, above the critical pressure 70bars, it uses T(gc for gas coolers) instead of T(condensing). How is one supposed to relate the gas cooler and compressor performances using the graphical* method?

* Conventional ways use Tc (X axis) and Qo(Y axis). With the introduction of T(gc), should the corresponding values of Qo be plotted on the same graph? or should the graph enter a new "transcritical performance region?"

Or can anyone here point me to a good gas cooler manufacturer which provide performance data?
