Discharge side........
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.

when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
When the ship is at the port, the water is shallow therefore we use high seawater suction. If the low seawater suction was used instead, impurities such as sand would be sucked into the system..
The suction line will be the larger line going into the compressor.
To compensate high suction volume during startup of he pump. the reducer area below the pipeline at the suction stores excess volume of fluid.
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
suction head is calculated wiht the formula head = 2.31 x psi so if your suction is 30psi then your head is around 60ft. of head. If your suction head is to high then there is not enough water to pump the needed psi for the task
Low side.
Common causes of high suction pressure in a refrigeration system can include a dirty or blocked evaporator coil, low airflow due to a dirty filter or a malfunctioning blower motor, overcharge of refrigerant, or a faulty expansion valve. It could also be due to issues with the compressor such as overheating or mechanical failure.
The number one reason why pumps cavitate is due to low pressure at the suction inlet, causing the fluid to vaporize and form bubbles. This can be caused by a variety of factors such as high liquid temperature, air leaks in the suction line, or a blocked or restricted suction line.
