A high subcooling value indicates what about the charge level in the condenser?

• A. High refrigerant in condenser
• B. Low refrigerant in condenser
• C. High refrigerant in evaporator
• D. Normal refrigerant in condenser

Answer: (A)

Subcooling shows how far the liquid refrigerant in the condenser is cooled below the condenser’s saturated liquid temperature. A high subcooling value means there’s more liquid refrigerant in the condenser than needed, so the liquid is cooled well below its saturation point as it leaves the condenser. That indicates the system is overcharged—the charge level in the condenser is high. This concept specifically relates to the condenser liquid, not the evaporator. Normal subcooling corresponds to a normal charge.
