If a refrigeration system is overcharged with refrigerant, what would be the result?

🔍 Key Concepts

• Effect of overcharging a refrigeration system with refrigerant on pressures and temperatures • Relationship between condenser pressure (head pressure) and refrigerant quantity • What conditions usually cause low suction pressure or short cycling on low-pressure cutout

💭 Think About

• Think about what happens inside the condenser when there is too much refrigerant. Does the condenser have more or less room to reject heat to the seawater/air? • Consider which condition is more likely with excess refrigerant: starved evaporator or flooded condenser? How does each affect suction and discharge pressures? • Ask yourself: which of these options would make the system run harder rather than more efficiently when it is overcharged?

✅ Before You Answer

• Compare which choice involves higher discharge (head) pressure and decide if excess refrigerant would increase or decrease that • Recall that low suction pressure and short cycling on low-pressure cutout are usually linked to a starved evaporator, not an overfilled system • Eliminate any option that suggests improved efficiency when the system is operating outside its designed refrigerant charge
