In refrigeration systems is it possible to change the refrigerant? If you alter the type of refrigerant whattype of changes is required for your refrigerator design? Compare two different refrigerants and discussyour proposal about the design change.
A space to be air-conditioned has a sensible heat load of 34.9 hp and a latent heat load of 6.97 hp. The space is to maintained at 24°C DB and 17°C WB. Outside air is at 32°C DB and 24°C WB temperatures. With a re-heater to satisfy the space conditions, the conditioned air will enter the space at 18°C.

A two-evaporatoor compression refrigeration system like that in the Figure below uses refrigerant-134a as the working fluid. The system operates evaporator 1 at 30 psia, evaporator 2 at 10 psia, and the condeser at 180 psia. The cooling load for evaporator 1 is 9000 Btu/h and that for evaporator 2 is 24,000 Btu/h.
