Question

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 24 C and exits at 1 bar. If the refrigerant undergoes a throttling process, what is the quality of the refrigerant exiting the expansion valve.

Answer 1

`h_(1) = h_2} = 293.45 KJ/kg`.

The quality of the refrigerant exiting the expansion valve is

`x_(2)=0.193596`.

Step-by-step explanation:

Fluid given Ammonia.

Inlet 1:-

Temperature
`T_(1)` =
`24^(o) C`.

Pressure
`P_(1)` = 10 bar.

Exit 2:-

Pressure
`P_(2)` = 1 bar.

Solution:-
