Abstract:
An ice water cooling system that adds chemical titration in cold water, the system comprising:an open chemical tank at atmospheric pressure located adjacent the bottom of a multi-story building structure; a pipeline circular system positioned within said building structure and including an upper part and a lower part, said upper part at an elevation higher than a water level in said tank; a first pipeline connected to said upper part and adapted to deliver water from said pipeline circular system to said tank and a second pipeline adapted to deliver water from said tank to said pipeline circular system; a pump positioned in said second pipeline for pumping water from the tank to the pipeline circular system; an isolating device adapted to isolate the pressure of the circular pipeline system comprising (i) a float-level ball connected to said first pipeline and positioned within said tank, said ball adapted to maintain a predetermined level of fluid in the tank by controlling a flow volume from the pipeline circular system to the tank, and (ii) a check valve positioned within said second pipeline, downstream of and adjacent said pump and configured to prevent water flow from said pipeline circular system back to said pump; and a cooling system coupled to the pipeline circular system.
