🔍 Key Concepts

• Thermostatic expansion valve (TXV) behavior when there is a restriction in the liquid line • Relationship between evaporator feeding, evaporator pressure, and compressor suction pressure • Effect of condenser condition and system charge on suction vs. discharge pressures

💭 Think About

• If the compressor suction pressure is lower than normal, what does that say about how much refrigerant vapor is returning from the evaporator? • Which condition(s) would tend to starve the evaporator instead of flooding it? • Which option(s) would mainly raise head pressure (discharge) rather than cause a low suction?

✅ Before You Answer

• Compare which options would cause overfeeding (too much refrigerant to evaporator) vs starving (not enough refrigerant) • Think about whether a restriction in the liquid line makes it easier or harder for refrigerant to reach the TXV and evaporator • Ask: which condition would most directly result in less refrigerant vapor reaching the compressor, leading to low suction pressure?
