Water cooling unit for conditioning systems

Abstract

A water cooling unit for conditioning systems, comprising, within a box-like container, an air precooling panel, provided with a matrix of through holes, associated with means for cooling a stream of external air that passes through the matrix of holes, at least one pair of laterally adjacent heat exchange batteries, for each pair of laterally adjacent batteries a first battery being for freecooling of the water entering an evaporator and the second battery being a condensation battery for a condenser of the evaporator, means for the exit outside the box-like container of the heated air that exits from the at least one pair of laterally adjacent heat exchange batteries, first means for hydraulic connection between the water return of an air-conditioning system and the water inlet of the at least one freecooling battery, and second means for hydraulic connection between the at least one freecooling battery and the evaporator.

What is claimed is: 
     
         1 . A water cooling unit for conditioning systems, comprising, within a box-like container,
 an air precooling panel, provided with a matrix of through holes, associated with means for cooling a stream of external air that passes through said matrix of holes,   at least one pair of laterally adjacent heat exchange batteries, for each pair of laterally adjacent batteries a first battery being for freecooling of the water entering an evaporator and the second battery being a condensation battery for a condenser of the evaporator,   means for the exit outside the box-like container of the heated air that exits from said at least one pair of laterally adjacent heat exchange batteries,   first means for hydraulic connection between the water return of an air-conditioning system and the water inlet of said at least one freecooling battery, and   second means for hydraulic connection between said at least one freecooling battery and said evaporator.   
     
     
         2 . The cooling unit according to  claim 1 , wherein said air precooling panel comprises a honeycomb panel the cells of which are open in the air passage direction. 
     
     
         3 . The cooling unit according to  claim 2 , wherein said means for cooling the stream of external air that passes through said precooling panel are constituted by
 an upper water dispenser, suitable to wet said honeycomb panel downward from above,   a lower collecting vessel,   a recirculation pump for the rise of the air precooling water from said lower vessel to said upper dispenser.   
     
     
         4 . The cooling unit according to  claim 1 , further comprising, within a box-like container:
 two opposite air precooling panels, arranged so as to affect the lateral faces of the box-like container substantially along its entire length, each precooling panel being provided with a matrix of through holes and being associated with means for cooling an external air stream that flows through said matrix of holes,   a series of pairs of laterally adjacent heat exchange batteries,   of each pair of laterally adjacent batteries, a first battery is for freecooling of the water in input to an evaporator and a second battery is a condensation battery for the evaporator,   means for the exit outside the box-like container of the heated air that exits from each pair of laterally adjacent heat exchange batteries,   first means for hydraulic connection between the water return from an air-conditioning system and the water inlet of the first freecooling batteries, and   second means for hydraulic connection between the first freecooling batteries and said evaporator.   
     
     
         5 . The cooling unit according to  claim 4 , wherein said heat exchange battery pairs are arranged two by two so as to face each other in the direction of the length of the box-like container, and are arranged, again two by two, so as to define a V-shaped configuration. 
     
     
         6 . The cooling unit according to  claim 4 , wherein the individual pairs of batteries are extended transversely to the box-like container so as to occupy it almost entirely or entirely along its width. 
     
     
         7 . The cooling unit according to  claim 4 , wherein the freecooling batteries of a group of freecooling batteries are connected in parallel, with a single loading duct and a single output duct, between which said freecooling batteries are connected in parallel.
