Patent ID: 8640479

Claim:
A cooling system for a room containing electronic data processing equipment that is arranged in racks, said system comprising: a raised floor construction dividing said room into a plenum space underneath said raised floor and a usable space above said raised floor; an air conditioning device for feeding cooled air to said plenum space; a cooling module arranged as a floor element of said raised floor, said cooling module comprising: a fan for providing a flow of cooled air from said plenum space to said usable space; at least two deflector units arranged side by side adjacent a first side of a rack and downstream of said fan for deviating the flow of cooled air provided by said fan such that the flow direction of said flow is controllable towards both an upper zone and a lower zone of a rack, each deflector unit being independently adjustable so as to enable division of said flow into at least two corresponding and simultaneous partial flows of independently adjustable flow direction, wherein each deflector unit includes a set of collectively adjustable parallel blades pivotably arranged within a support frame and having a curved cross-section, said blades configured for deviating the flow of cooled air provided by said fan by inclination of said blades and for preferring a flow direction towards said upper zone or said lower zone of said rack; a control device connected to the deflector units of said cooling module for automatically controlling the flow direction of said partial flows by adjustment of said deflector units, wherein said control device is arranged for independently adjusting each of said deflector units so as to control the flow direction of each of said partial flows.
