Cooling system control and servicing based on time-based variation of an operational variable

摘要

Automated control of a cooling system cooling at least one electronic component is provided. The control includes monitoring over a period of time variation of an operational variable of the cooling system or of the at least one electronic component, and based, at least in part, on variation of the operational variable over the period of time, automatically determining whether to adjust control of the cooling system to limit variation of the operational variable. In one implementation, depending on the variation of the operational variable, and whether control of the cooling system has been previously adjusted, the method may further include automatically determining a probability of fail or an expected residual life of the cooling system, and responsive to the predicted probability of fail exceeding a first acceptable threshold or the expected residual life being below a second acceptable threshold, automatically scheduling for a cooling system repair or replacement.

1. A method of operating a cooling system cooling at least one component, the method comprising;
monitoring over a period of time variation of an operational variable of the cooling system or of the at least one component cooled by the cooling system; based, at least in part, on the variation of the operational variable over the period of time, determining whether to adjust control of the cooling system to limit the variation of the operational variable; and determining, from the variation of the operational variable over the period of time, an oscillation metric representative of the variation of the operational variable over the period of time, and wherein the determining whether to adjust control of the cooling system comprises determining whether the oscillation metric exceeds a set threshold, and based on the oscillation metric exceeding the set threshold, the method further comprises adjusting at least one control parameter of the cooling system to, at least in part, reduce the oscillation metric.
