🔍 Key Concepts

• Thermostatic Expansion Valve (TXV) operation and what it controls in the system • Effect of overcharging/too much refrigerant on condenser and system pressures in an air‑cooled system • Difference between symptoms caused by excess refrigerant charge vs control setting (like low box temperature setting)

💭 Think About

• Think about what happens in the condenser of an air‑cooled system when there is more refrigerant than it can comfortably condense and store as liquid. How does that affect pressures? • Which of the options would most directly be a result of system pressures being pushed higher, rather than a thermostat calling for more cooling? • TXV meters refrigerant to maintain superheat at the evaporator outlet. With an excessive charge, which component (compressor, condenser, evaporator, or box temperature) is MOST likely to show the first clear symptom?

✅ Before You Answer

• Compare which choices are clearly related to pressure (head/discharge pressure) versus temperature control. • Ask yourself whether a properly working thermostat and TXV would still allow the box temperature to go unusually low just because the system is overcharged. • Consider normal troubleshooting practice: when a tech finds an overcharged air‑cooled system, which gauge reading (suction vs discharge) is characteristically high?
