How increase in evaporator increases Refrigeration effect?

AI Thread Summary
An increase in evaporator temperature can lead to a higher refrigeration effect, which is defined as the quantity of heat absorbed by the refrigerant from the refrigerated space. This concept may seem counterintuitive, as refrigeration effect relates to efficiency rather than the actual temperature achieved. The area under the curve in the TS diagram of a vapor compression system illustrates this relationship. Understanding the TS diagram for refrigerants like R134a can clarify how higher evaporator temperatures can enhance efficiency. Ultimately, the refrigeration effect measures the system's efficiency in heat absorption, not the coldness of the output.

It appears very non intuitive to me seeing TS diagram of vapour compression system; Area under the curve increases. But how seriously how higher evaporator temperature will lead to higher refrigeration effect. Refrigeration effect means lower temperature.

Put 'refrigeration effect' in search and you get this ..."Net Refrigeration Effect is. "the quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling"."

Refrigeration effect is a measure of how efficient the refrigerator is (in it's use of fluid), not how cold it gets.

Just see the TS diagram of say taking R134a refrigerant. I am not getting it :( please help

The issue is that you are arguing against a definition. The definition is as @oz93666 said.

Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
