Carnot efficiency depends upon temperature limit not working substance...

Carnot cycle is hypothetical cycle which is used to compare the thermal efficiency with actual cycles or engines..and comeing to your question..why does Carnot cycle efficiency depends on temperature limits…??

It is based on second Carnot principle..which says..

“The efficiency of all reversible heat engines operating between the same two reservoirs are the same”

It means that all reversible engines have the same thermal efficiency when operating between the same two reservoirs,that is the efficiency of a reversible engine is independent of the working fluid employed and it's properties,and the way is cycle executed.….and so the thermal efficiency of reversible heat engine is a function of the reservoir temperature only… hence..The efficiency of Carnot cycle is given by formula 1-T2/T1….and not as 1-Q2/Q1…

Increasing T1 and decreasing T2..efficiency increases..and for 100 % efficiency T2 should be zero ,which is not possible in actual case...

And to understand the concept more..refer a book..

Lubricants are essential for the performance and longevity of a refrigeration system. The choice of lubricant depends on the system, the refrigerant, and the type of application.There are several categories of oils:Mineral oils: They are particularly suited for use with CFC (R11, R12), HCFC (R22, R142b, R123) refrigerants, and ammonia.Alkyl Benzene Oils (AB): AB oils are especially recommended for refrigerants like R-22 and HCFC blends.Poly Alpha Olefins (PAO): It can be described as ‘mineral synthetic oils.’ PAO oils can be used in refrigeration systems working in extreme conditions with R-22 or ammonia. It has a low pour point and excellent thermal stability.Poly Alkylene Glycols (PAG): These were the first oils developed for use with HFC refrigerants and are perfectly miscible with these products.Polyol Ester Oils (POE): POE constitutes the second generation of lubricants developed for use with HFC’s (R134a, R152
