The refringent enters in the evaporator as in the ideal vapour compression cycle.
-
A.
high-pressure liquid
-
B.
low-pressure liquid
-
C.
low-pressure liquid-vapor mixture
-
D.
low-pressure vapor
Correct Answer:
C. low-pressure liquid-vapor mixture
Explanation:
In an ideal vapor compression refrigeration cycle, the refrigerant undergoes an expansion process before reaching the evaporator. As it passes through the expansion valve or capillary tube, its pressure and temperature drop significantly, causing a portion of the liquid to flash into gas. Consequently, the substance enters the evaporator as a low-pressure liquid-vapor mixture, where it then absorbs heat from the surroundings to complete the evaporation process.
