Abstract:
1. A refrigerated water pumping system for pumping water from a water source through a water transport line of said system operatively connected to the water source to at least one misting nozzle disposed within an enclosure, said system comprising: a compressor for compressing a refrigerant received from a refrigerant line connected thereto; a condenser operatively connected to said compressor by said refrigerant line for condensing said refrigerant after said compressing; a pump disposed on the water transport line for pumping said water at high water pressure therethrough, thereby converting the water into a high-pressure water; a post-pumping heat exchanger operatively connected to the water transport line between said pump and the misting nozzle and to said refrigerant line between said condenser and said compressor for receiving said refrigerant from said condenser, said refrigerant absorbing heat from said high-pressure water in said post-pumping heat exchanger for refrigerating said high-pressure water into a high-pressure refrigerated water; and a pre-pumping heat exchanger operatively connected to the water transport line between the water source and the pump and to said refrigerant line between said condenser and said post-pumping heat exchanger, wherein said refrigerant is compressed in said compressor into a high-pressure refrigerant vapor and said condenser condenses said refrigerant from said high-pressure refrigerant vapor into a high pressure refrigerant liquid, said pre-pumping heat exchanger receives said water from said water source and said high pressure refrigerant liquid from said condenser for refrigerating said water into partially refrigerated water by absorption of heat therein by said high-pressure refrigerant liquid, thereby at least partially evaporating said high-pressure refrigerant liquid into intermediate-pressure refrigerant vapor for circulation in said refrigerant line to said post-pumping heat exchanger from, said partially refrigerated water being pumped by said pump into high-pressure refrigerated water to said post-pumping heat exchanger for refrigeration therein into said high-pressure refrigerated water by absorption of heat by said intermediate-pressure refrigerant vapor.
