  • Pumped refrigerant cooling system with 1+1 to N+1 and built-in redundancy
    Patent number: 10288324
    Abstract: A pumped refrigerant cooling system having cooling units with associated pumping units for providing working fluid to the cooling unit to enable cooling of a space. The pumped refrigerant cooling system also includes a redundant pumping unit which is activated when a primary pumping unit associated with a cooling unit becomes inactive. The primary pumping unit is deactivated in favor of the redundant pumping unit. Once the primary pumping unit is placed in a condition suitable for reactivation, the redundant pumping unit is deactivated, and the primary pumping unit is reactivated.
    Type: Grant
