If one increased superheat on the inlet of a compressor, what would most likely happen?

Increasing superheat at the inlet of a compressor primarily means that the refrigerant vapor entering the compressor is at a higher temperature than it would be at a lower superheat. Superheat reflects the temperature of the vapor above its saturation temperature for a given pressure. When superheat is increased, the vapor's energy content rises, leading to a higher discharge temperature.

As the refrigerant vapor is compressed, it undergoes a rise in both pressure and temperature. The increase in energy from the superheated vapor directly contributes to a higher discharge temperature as it exits the compressor. This can impact system efficiency and may also affect other components, such as the condenser and evaporator, by altering the overall cycle performance.

Thus, the correct outcome of increasing superheat is a rise in discharge temperature, as the additional heat energy from the superheated vapor is absorbed during the compression process.
