How many gallons of sea water flow are queried for every 12,000 BTU's (1 Ton) of air conditioning?

In marine air conditioning, the amount of seawater flow required for effective cooling is a crucial factor. For systems designed to deliver 12,000 BTUs of cooling, it is generally established that a flow rate of approximately 250 gallons per hour is necessary. This figure is based on the ability of seawater to absorb heat efficiently.

The cooling process involves transferring heat away from the air conditioning system to the seawater. To remove 12,000 BTUs of heat effectively, a certain volume of seawater must flow through the heat exchanger, ensuring that it can absorb enough heat without significantly raising its temperature. The recommendation of 250 gallons per hour corresponds to the optimal balance between heat transfer efficiency and the thermal capacity of the seawater.

By maintaining this flow rate, the system can operate effectively and prevent overheating, which is vital for the longevity and performance of both the air conditioning system and the marine environment. Thus, the choice of 250 gallons per hour as the necessary flow rate aligns with accepted engineering standards in marine HVAC applications.
