In the refrigeration system, a shortage of refrigerant is indicated by which of the following?

Question 1 of 27070

In the refrigeration system, a shortage of refrigerant is indicated by which of the following?

🔍 Key Concepts

• Behavior of refrigerant flow when the system is undercharged • What a sight glass shows in a liquid refrigerant line • How suction and discharge (head) pressures typically change with too little refrigerant

💭 Think About

• Think about what happens to the liquid line if there is not enough refrigerant to keep it completely full • Consider whether suction and head pressures tend to be high or low when there is a shortage of refrigerant in the system • Ask yourself: which option directly indicates intermittent liquid flow rather than steady, solid liquid flow?

✅ Before You Answer

• Verify which device in the liquid line is specifically used for visual indication of refrigerant condition (sight glass) • Check whether high suction pressure and high head pressure are usually signs of overcharge or undercharge • Confirm what happens at the high pressure cut-out switch when the system is over-pressurized versus undercharged
