Accepted Answer

Option B: thermostatic expansion valve. Flash gas formation normally occurs inside the thermostatic expansion valve as high-pressure liquid refrigerant undergoes an abrupt pressure drop across the orifice, causing a fraction of the liquid to flash into vapor and cool the remaining mixture.
