Suction Pressure - SensorsONE

Suction Pressure. Suction pressure is a negative difference in pressure generated between two points which draws a gas or a liquid from a higher to a lower pressure state. For example if the inlet pressure of a vacuum pump is at 900 ar absolute and it is connected to a closed chaer at an atmospheric pressure of 1000 ar absolute, the

Discharge pressure - Wikipedia

Discharge pressure (also called high side pressure or head pressure) is the pressure generated on the output side of a gas compressor in a refrigeration or air conditioning system. The discharge pressure is affected by several factors: size and speed of the condenser fan, condition and cleanliness of the condenser coil, and the size of the discharge line.
