In a TXV system, which list correctly identifies high-pressure side components?

• A. 1/2 compressor; evaporator; receiver dryer; 1/2 TXV
• B. 1/2 compressor; condenser; evaporator; 1/2 TXV
• C. Condensor; receiver dryer; 1/2 TXV
• D. 1/2 compressor; condenser; receiver dryer; 1/2 TXV

Answer: (D)

The high-pressure side includes everything from the compressor discharge up to the metering device that feeds the evaporator. After compression, refrigerant goes to the condenser where it remains at high pressure while releasing heat. It then moves to the receiver/drier, which stores refrigerant and removes moisture, still on the high-pressure side. The thermostatic expansion valve sits right before the evaporator and throttles the high-pressure liquid down to low pressure, feeding the evaporator. Because these components handle high-pressure refrigerant and lie between the compressor and the evaporator, they belong on the high-pressure side. The evaporator itself operates on the low-pressure side, so it isn’t included.
