SUMMARY
The discussion centers on the relationship between evaporator temperature and refrigeration effect in vapor compression systems, specifically using R134a refrigerant. It is established that the refrigeration effect is defined as the quantity of heat absorbed by the refrigerant from the refrigerated space, which measures the efficiency of the refrigeration process rather than the temperature achieved. The TS diagram illustrates that an increase in evaporator temperature can lead to a higher refrigeration effect, challenging common intuitions about cooling efficiency.
