The high pressure side pressure is sometimes called discharge pressure or which other term?

• A. Ambient pressure
• B. Suction pressure
• C. Head pressure
• D. Crankcase pressure

Answer: (C)

On the high-pressure side of a refrigerant system, the pressure reading is known as discharge pressure, and another common term for that same pressure is head pressure. The “head” refers to the discharge side of the compressor and condenser, where the refrigerant is at its highest pressure as it leaves the compressor. Ambient pressure is just atmospheric; suction pressure is the low-side pressure before the compressor; crankcase pressure relates to the compressor crankcase, not the refrigerant path. So the best match for the alternative term is head pressure.
