Abstract
A method for controlling a cooling system based on a heat dissipation of an electronic module and an ambient air temperature includes determining a combination of individual controls on components of the cooling system that achieve a specific amount of cooling based on a cooling power relationship for the plurality of components, the heat dissipation of the electronic module and the ambient air temperature, and applying the individual controls to the plurality of components.
Claims26
A method for controlling a cooling system comprising:
- determining a relationship between a delta temperature and a power usage for each of a plurality of cooling components of said cooling system;
- determining a low power setting from a combination of said relationships for said plurality of cooling components to maintain a temperature of interest at or below a target temperature;
- generating a control signal controlling a combination of said plurality of cooling components according to said low power setting;
- and
- determining an error signal, wherein said control signal is determined based on the basis of a scaled correction signal and said error signal, and wherein said scaled correction signal is a feedforward signal determined based on an outdoor air temperature and a heat load on the cooling system, and said error signal is a feedback signal.
A computer program product for controlling a cooling system, the computer program product comprising:
- a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to determine a relationship between a delta temperature and a power usage for each of a plurality of cooling components of said cooling system;
- computer readable program code configured to determine a low power setting from a combination of said relationships for said plurality of cooling components to maintain a temperature of interest at or below a target temperature;
- computer readable program code configured to generate a control signal controlling a combination of said plurality of cooling components according to said low power setting;
- and
- computer readable program code configured to determine an error signal, wherein said control signal is determined based on the basis of a scaled correction signal and said error signal, and wherein said scaled correction signal is a feedforward signal determined based on an outdoor air temperature and a heat load on the cooling system and said error signal is a feedback signal.
