A food storage chamber requires a refrigeration system

Reference no: EM13691620

Problem- A food storage chamber requires a refrigeration system of 15-ton capacity operating at an evaporator temperature of -8Â°C and a condenser temperature of 30Â°C. Refrigerant ammonia (R-717) is used and the system operates at saturated conditions. Determine:

(a) C.O.P.

(b) Refrigerant flow rate

Repeat problem, with the refrigerant subcooled by 5°C before entering the expansion valve, and the vapor superheated by 6°C.

Please define why you think that's the right answer
