Question: Repeat Prob. 1119E using appropriate software if ammonia is used in place of refrigerant-134a. Data From Q#19: A refrigerator uses refrigerant-134a as its working fluid

Repeat Prob. 11–19E using appropriate software if ammonia is used in place of refrigerant-134a.

Data From Q#19:

A refrigerator uses refrigerant-134a as its working fluid and operates on the ideal vapor-compression refrigeration cycle. The refrigerant evaporates at 5°F and condenses at 180 psia. This unit serves a 45,000 Btu/h cooling load. Determine the mass flow rate of the refrigerant and the power that this unit will require.
