Redo Problem 5.1 using Aspen Plus.

Problem 5.1

a. An automobile air conditioner uses the vapor compression refrigeration cycle with HFC-134a as the refrigerant. The operational temperature of the evaporator is 7^◦C and that of the condenser is 45^◦C. Determine the coefficient of performance of this air conditioning system and the amount of work needed for each kilojoule of cooling provided by the air conditioner. 

b. For service in high-temperature areas, the condenser temperature may go up to 65^◦C. How would the answers to part (a) change in this case?
