The recommended sea-water flow, per ton of cooling is GPH:

The recommended sea-water flow rate, which is often expressed in gallons per hour (GPH), is critical for effective cooling in marine air conditioning systems. For each ton of cooling capacity, it is generally advised that a system circulates approximately 250 GPH of seawater. This flow rate ensures that there is adequate heat exchange taking place, which is essential for maintaining optimal performance and efficiency of the air conditioning system.

When seawater circulates at this rate, it helps to effectively remove the heat absorbed by the refrigerant, allowing the system to operate efficiently while preventing overheating. Insufficient flow rates can lead to inadequate cooling performance and increased wear on the components of the system.

Thus, understanding that a flow rate of 250 GPH per ton is the standard provides important guidance for anyone working with marine air conditioning equipment. This information is vital for system design, maintenance, and troubleshooting in the field.
