🔍 Key Concepts

• Behavior of suction pressure and temperature when refrigerant flow increases or decreases • Effect of a thermostatic expansion valve (TXV) being too far open vs too far closed • How flow restrictions (like clogged strainers or partially closed valves) impact pressure and temperature on the suction side

💭 Think About

• If the compressor is seeing high suction pressure but low suction temperature, does that suggest more or less refrigerant reaching the evaporator? • What happens to evaporator pressure and outlet temperature when the expansion valve is starved vs when it is overfeeding? • Would a restriction in the liquid line or a partially shut king valve tend to make suction pressure higher or lower?

✅ Before You Answer

• Compare each option’s effect on refrigerant flow rate to the evaporator (increased vs decreased) • For each choice, decide whether the evaporator would run starved (warm, low pressure) or flooded/overfed (cold, higher pressure) • Eliminate any options that would clearly cause low suction pressure instead of the stated high suction pressure
