Seawater Heat-Rejection Loop
Seawater Heat-Rejection Loop: Converting Coastal Heat-Sink Advantage into Sustainable Cooling Capacity Coastal data centers are often viewed as having a natural advantage in heat rejection, as the ocean represents an enormous and readily available heat sink. When data-hall heat can be rejected to seawater in a stable and well-controlled manner, chiller runtime can be reduced.
