Air pressure measurement based cooling

A method comprising:

• providing a system comprising a plurality of component racks located within a structure, a cooling system within said structure, a plurality of pressure measurement devices within said structure, an alarm system, and a computing system connected to said plurality of pressure measurement devices, wherein each component rack of said plurality of component racks comprises at least one exothermic apparatus, wherein said structure comprises a plurality of warm air aisle spaces and a plurality of cold air aisle spaces located between said plurality of component racks;
• feeding, by said cooling system, cold air into each cold air aisle space of said plurality of cold air isle spaces, wherein said cold air flows through said component racks resulting in displacement of warm air from each said at least one exothermic apparatus, and wherein said warm air flows into said plurality of warm air aisle spaces and is directed back to said cooling system;
• measuring, by said plurality of pressure measurement devices, differential pressure values between said plurality of cold air aisle spaces and said plurality of warm air aisle spaces;
• monitoring, by said computing system, said differential pressure values;
• performing, by said computing system, calculations associated with said differential pressure values;
• controlling, by said computing system, a fan speed of at least one fan within said cooling system based on said calculations;
• and
• notifying, by said computing system executing said alarm system, a user if any of said pressure values exceeds a predetermined threshold.

A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for controlling a system comprising a plurality of component racks located within a structure, a cooling system within said structure, an alarm system, and a plurality of pressure measurement devices within said structure, wherein each component rack of said plurality of component racks comprises at least one exothermic apparatus, and wherein said structure comprises a plurality of warm air aisle spaces and a plurality of cold air aisle spaces located between said plurality of component racks, said method comprising:

• feeding, by said cooling system, cold air into each cold air aisle space of said plurality of cold air isle spaces, wherein said cold air flows through said component racks resulting in displacement of warm air from each said at least one exothermic apparatus, and wherein said warm air flows into said plurality of warm air aisle spaces and is directed back to said cooling system;
• measuring, by said plurality of pressure measurement devices, differential pressure values between said plurality of cold air aisle spaces and said plurality of warm air aisle spaces, wherein said computing system is connected to said plurality of pressure measurement devices;
• monitoring, by said computing system, said differential pressure values;
• performing, by said computing system, calculations associated with said differential pressure values;
• controlling, by said computing system, a fan speed of at least one fan within said cooling system based on said calculations;
• and
• notifying, by said computing system executing said alarm system, a user if any of said pressure values exceeds a predetermined threshold.
