Increase of the Efficiency of the System of Cooling of Data Processing Center Servers

Abstract

The article describes the method of construction of energy-efficient air-conditioning systems in the premises of modern data processing centers (DPC) which takes into account the location geometry of the processing equipment. The technique is obtained on the basis of scientific and practical research the results of which are the following:1)The authors proposed a criterion allowing a quantitative estimation of the clutter of IT premises with the equipment in the form of the coefficient of complexity Kc which adapts the standard method of calculating the fluid dynamics of air flow to the given conditions.2)The authors experimentally studied the connection between the location of the air conditioner and the efficiency of cooling equipment. It has been found that there is a control point in which a stream of cold air for maximum cooling efficiency needs to be entered. Dependence for finding the coordinates of this point is given.3)The authors reveal the experimental dependence for the definition of coordinates of a cooling unit according to the control point and the degree of difficulty to ensure the best cooling effect for this power of conditioners.4)The authors implemented this technique at the reconstruction of data processing center on service of a payment system to give a high resource saving effect.
