A refrigerator in a meat warehouse must keep a low temperature of -20°C and the outside temperature is 25°C. Ammonia is used as the refrigerant which must remove 10 kW from the cold space. Compute for the flow rate of the ammonia needed assuming a standard vapor compression refrigeration cycle with a condenser at 25°C. Find the enthalpy of the stream exiting the evaporator, condenser, and throttling (expansion) valve.
