Task 2 Select a reasonable pressure for the evaporator and condenser in the following scenarios: A) A refrigerator that operates on the ideal vapor-compression cycle with refrigerant-134a is to maintain the refrigerated space at -10°C while rejecting heat to the environment at 25°C. Select reasonable pressures for the evaporator and the condenser and explain your choice.
