Which consequence results when a refrigeration system's expansion valve malfunctions in regulating liquid refrigerant flow?

💡 Explanation

Excessive refrigerant entering the evaporator leads to liquid flood-back; the mechanism is unrestricted phase transition. This increases condenser pressure greatly because unvaporized refrigerant bypasses the intended cooling process, therefore raising head pressure rather than improving operational efficiency.
