Which outcome occurs when pressurized liquid refrigerant undergoes rapid expansion through an orifice in a refrigeration system?

💡 Explanation

When pressurized liquid refrigerant expands, it undergoes the Joule-Thomson effect because the expansion occurs at constant enthalpy, causing a temperature decrease in the fluid. Therefore a temperature drop results, rather than pressure increase, superheating, or decomposition, each requiring different thermodynamic processes.
