closed-loop cooling

a system that acts as a heat sink for heat-rejecting building and medical equipment by recirculating water. Because the water is sealed within the system, some closed-loop cooling systems use nonpotable water (such as recycled process water harvested from an air handler's cooling coil condensate).
