Abstract:
Cooling equipment adapted for cooling and recirculating water discharged from a to-be-cooled machine, said cooling equipment comprising:at least one cooling tower with an extended surface to be wetted by the water so that a portion of the water evaporates; at least one air flow generator device for forcing air extracted from outside of the cooling equipment to flow through said at least one cooling tower so as to cool the water and thereby minimize evaporation of the water; at least one water controller for discharging another portion of the water from the cooling equipment and for introducing new water into the cooling equipment when the temperature of the water at a water entry port or at a water exit port of the cooling equipment reaches a predetermined value; and, at least one closed cycle frigorific circuit including: at least one condenser, and an evaporator disposed downstream of said at least one cooling tower with respect to the flow of the water for exchanging heat with the cooled water in said at least one cooling tower, and for thereby recirculating the cooled water back to the to-be-cooled machine, wherein said at least one condenser is disposed upstream or downstream of said at least one cooling tower with respect to the air flow, and wherein at least one of said at least one condenser is activated.
