A method and system for cooling air within an enclosure. The enclosure includes a cooling system and a remaining portion of the enclosure that is external to the cooling system. An outside air temperature of air entering the cooling system from outside the enclosure is monitored. A blowing air temperature of air in the cooling system at the outlet of the cooling system is monitored. A first inlet of the enclosure is controlled to be fully open or fully closed, in dependence on the monitored outside air temperature. A second inlet of the enclosure is controlled by adjusting an amount of opening of the second inlet, in dependence on the monitored blowing air temperature. A valve in a secondary water circuit of the cooling mechanism is controlled by adjusting an amount of opening of the valve, in dependence on the monitored outside air temperature.

Variable air cooling system for data centers

A method and system for variable air cooling for data centers. The system may include: an enclosure to be cooled suitable for housing hardware components; a cooling system including: a first air input for controllably allowing input of outside air from outside the enclosure; a second air input for controllably allowing input of recycled air from the enclosure; a selectively activatable cooling mechanism; an air output for allowing output of air into the enclosure; a first temperature monitor for monitoring an outside air temperature of air outside the enclosure; a second temperature monitor for monitoring a blowing air temperature of air at the air output; and a control mechanism for controlling an operation of the first air input, the second air input, and the cooling mechanism dependent on a monitored outside air temperature at the first temperature monitor and a monitored blowing air temperature at the second temperature monitor.

A cooling management system including component racks, a cooling system, pressure measurement devices, and a computing system within a structure. Each component rack includes an exothermic apparatus. The structure includes warm air aisle spaces and cold air aisle spaces located between the component racks. The cooling system feeds cold air into each cold air aisle space. The cold air flows through the component racks resulting in displacement of warm air from each exothermic apparatus. The warm air flows into the warm air aisle spaces and is directed back to the cooling system. The pressure measurement devices measure differential pressure values between the cold air aisle spaces and the warm air aisle spaces. The computing system monitors the differential pressure values, perform calculations associated with the differential pressure values, and control a fan speed of at least one fan within the cooling system based on the calculations.

Air pressure measurement based cooling

System and method for controlling energy consumption in a data center. An embodiment includes: segregating hot air from cold air by preventing hot air exhausted from hot aisles from flowing into cold aisles; measuring temperature and relative humidity values of the segregated hot and cold air; detecting temperature and relative humidity values of outside air; mixing the segregated hot air with a volume of the outside air, the volume of the outside air depending on a result of the measuring and the detecting; measuring temperature and relative humidity values of the mixed air; comparing the temperature and relative humidity values of the mixed air and the temperature and relative humidity values of the segregated cold air to IT specifications; cooling the mixed air based on a result of the comparison; and providing the cooled mixed air in the cold aisles.

System, method, and computer program product for controlling energy consumption in data centers

A system is provided for positioning a plurality of cards in an electronic module intended to be plugged into a backplane. The system includes a spacing element comprising a succession of spacers of increasing section (diameter). Spacers are arranged end to end and are preferably cylindrical. The difference of section between successive spacers forms a kind of stair step or shoulder. These successive steps position the electronic cards parallel to one another, with a predetermined spacing which corresponds to the spacing of the backplane connectors. Fastening means, such as a nut, are associated with the steps for maintaining the cards. The cards are bored so that the spacing element can be inserted and the nuts applied. The size of the hole in each card is such that the surface around the hole can be pressed against the corresponding shoulder by means of the nut installed on the opposite side.
