Patent ID: 7270174

Claim:
A method of facilitating operation of a cooling system for a computing environment, the method comprising: automatically checking at least one coolant loop of the cooling system for a leak, the automatic checking including isolating the at least one coolant loop from coolant flow through the cooling system and checking for drop in coolant pressure within the at least one coolant loop; upon detection of a drop in coolant pressure in the at least one coolant loop, retaining isolation of the at least one coolant loop from coolant flow through the cooling system, the automatic checking further comprising for each coolant loop of the at least one coolant loop of the cooling system: Closing a first valve of the coolant loop while keeping a second valve of the coolant loop open; Reading a first pressure value of the coolant in the coolant loop while the first valve is closed and the second valve is open; Closing the second valve of the coolant loop; Waiting a defined interval after closing the second valve of the coolant loop; Reading a second pressure value of the coolant in the coolant loop while both the first pressure valve and the second pressure valve are closed; and, Determining whether the difference of the first pressure value less the second pressure value is greater than a defined decay value, and if so, retaining isolation of the coolant loop from coolant flow through the cooling system.
