What type of loop in a cooling system is typically supplied by seawater?

In cooling systems, particularly those associated with marine environments and naval applications, seawater is typically used in the condenser loop. The condenser loop is a critical part of the cooling process as it involves transferring heat absorbed from the primary system to the seawater, which serves as a heat sink. When the refrigerant or coolant inside the system enters the condenser, it releases heat to the flowing seawater, allowing the system to maintain lower operating temperatures.

The primary loop, on the other hand, is responsible for circulating the refrigerant or coolant through the major components such as the evaporator and the compressor. It does not interact directly with the seawater. Secondary loops are utilized for distributing cooled or heated fluids to other systems or components, while the evaporative loop is involved in systems that utilize evaporation for cooling.

Thus, seawater is primarily tied to the condenser loop in marine cooling systems, where it effectively dissipates heat to maintain optimal performance of onboard equipment and systems.
