Q

If the running suction pressure for an operating refrigeration compressor of a TXV controlled refrigeration system is below normal, the cause may be which of the following?

🔍 Key Concepts

• Relationship between suction pressure and evaporator/refrigerant flow • What a TXV (thermostatic expansion valve) actually controls in the system • How restrictions or blockages on the low side affect suction pressure

💭 Think About

• Ask yourself: does this condition (low suction pressure) suggest too much refrigerant reaching the evaporator, or not enough? • Which option would tend to starve the evaporator of refrigerant rather than flood it? • Which of the listed conditions would act like a partial blockage on the suction side of the compressor?

✅ Before You Answer

• Eliminate any options that would clearly cause higher suction pressure, not lower • Focus on what would reduce the mass flow of refrigerant vapor returning to the compressor • Check which option describes something located on the suction line/low-pressure side that could become restricted or fouled
