4: Consider a vapor refrigeration cycle.
a: Draw the T-s diagram of the reversed Carnot Cycle and describe what kind of problem each process of the cycle has explicitly. (We use the mixture of liquid and vapor as its working fluid.)
b: Draw a T-s diagram in the ideal refrigeration cycle and label each process explicitly. Write down the COP in terms of enthalpy.
c: There are the multipurpose refrigeration system and the multistage refrigeration system to improve the ideal refrigeration system. Describe their cycles in terms of the property diagrams explicitly and discuss the reasons why they are necessary.
d: Discuss the current status of existing refrigerants and describe how to resolve their problems explicitly.
