Which components are on the high-pressure side of an orifice-tube A/C system?

Which components are on the high-pressure side of an orifice-tube A/C system?

• A. 1/2 compressor; evaporator; 1/2 orifice tube
• B. 1/2 compressor; evaporator; condenser
• C. 1/2 compressor; condenser; 1/2 orifice tube
• D. evaporator; accumulator; 1/2 orifice tube

Answer: (C)

In an orifice-tube A/C system, the high-pressure side includes everything from the compressor discharge through the condenser up to the metering device. After compression, the refrigerant is at high pressure as it goes into the condenser and remains high pressure until it passes through the upstream portion of the metering device. The evaporator and accumulator operate on the low-pressure side after the throttling by the orifice tube. So the components that belong on the high-pressure side are the discharge portion of the compressor, the condenser, and the upstream portion of the orifice tube. That’s why the correct choice lists the discharge side of the compressor, the condenser, and the upstream portion of the orifice tube.
