A refrigerator using R-12 as the working fluid

keeps the refrigerated space at 2158C in an environment at

308C. You are asked to redesign this refrigerator by replacing

R-12 with the ozone-friendly R-134a. What changes in the

pressure levels would you suggest in the new system? How

do you think the COP of the new system will compare to the

COP of the old system?

Solutions

Expert Solution

The refrigerated space temperature is given in correct as 2158°C

I am assuming it to be 215.8 K or -57.2°C and environment temperature to be 308K or 35°C.
