Ammonia enters the expansion valve of a refrigeration system at a pressure of
(10)/(b)ar and a temperature of
20\deg Cand exits at 3.0 bar. The refrigerant undergoes a throttling process. Determine the temperature, in
\deg C, and the quality of the refrigerant at the exit of the expansion valve. Step 1 Determine the temperature of the refrigerant at the exit, in
\deg C.
