Abstract: A method for operating a cooling system for a data center comprises receiving temperature of a coolant from a temperature sensor circuit and determine whether the temperature is more than a threshold temperature. The method further comprises determining one or more racks that meet a cooling capacity associated with the cooling demand of the data center and determining one or more pumps that meet a required flow of the refrigerant according to the cooling demand of the data center if it is determined that the temperature is more than the threshold temperature. The method further comprises communicating a first electronic signal to each of the one or more racks to activate the one or more racks and communicating a second electronic signal to each of the one or more pumps to activate the one or more pumps.

Abstract: A method for operating a cooling system for a data center comprises receiving sensor data indicating an attribute associated with a component of the cooling system, where the attribute is the temperature, pressure, or voltage level. The method further includes comparing the received attribute with an expected level for the attribute and determining that the component has failed based on the comparison, where determining the failure comprises determining that the received attribute deviates from the expected level by more than a pre-defined threshold. In response to determining the component has failed, the method comprises communicating a first electronic signal to a multi-valve manifold connected to the first component to isolate it from other components, wherein the first electronic signal causes a valve that allows the refrigerant flowing into the first component to be closed.
