A refrigerated water pumping system provides high-pressure refrigerated water to misting nozzles situated in a livestock enclosure for housing livestock and adapted for converting the high-pressure refrigerated water into a fine mist or fog of water droplets at a target water temperature for evaporation in the enclosure to provide cooling of the enclosure to a target enclosure temperature. The system comprises a pump and a post-pumping heat exchanger, with the water being pumped by pump into high-pressure water. The high-pressure water is subsequently refrigerated into high-pressure refrigerated water having the target temperature by absorption of a target heat from the water by a refrigerant in the post-pumping heat exchanger, including any heat absorbed by water during pumping in pump.

The system of claim 1, wherein said system further comprises a system controller for controlling operation of said compressor and said pump. 3. The system of claim 1, 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 high pressure refrigerant liquid absorbing said heat in said post-pumping heat exchanger. 4. The system of claim 3, wherein said post-pumping heat exchanger is a tubular heat exchanger through which the water transport line and said refrigerant line pass in contacting engagement with each other, said contacting engagement enabling absorption of said heat from said high-pressure water through the water transport line and said refrigerant line by said high-pressure refrigerant liquid in said post-pumping heat exchanger. 5. The system of claim 1, further comprising a refrigerant accumulator connected to said compressor and said post-pumping heat exchanger by said refrigerant line, wherein said refrigerant is at least partially evaporated by said absorption of said heat into low-pressure refrigerant vapor for circulation from said post-pumping heat exchanger through said refrigerant line and said refrigerant accumulator to said compressor, said refrigerant accumulator receiving and accumulating an unevaporated portion of said refrigerant from said post-pumping heat exchanger as refrigerant liquid for impeding flow of said unevaporated portion to said compressor. 6.

The system of claim 1, wherein said pump is adapted for pumping the water as said high-pressure refrigerated water through a nozzle aperture of the misting nozzle, said nozzle aperture having a diameter of about 2 microns for converting said high-pressure refrigerated water into a mist of refrigerated water droplets. 9. The system of claim 1, wherein said condenser is a refrigerant-to-air condenser wherein cooled air circulating therein absorbs refrigerant heat from said refrigerant, condensing said refrigerant. 10. The system of claim 1, wherein said heat exchanger refrigerates said high-pressure water to a predetermined target water temperature varying between about 79 degrees Fahrenheit and about 89 degrees Fahrenheit. 11. The system of claim 2, further comprising a water temperature sensor operatively connected to said system controller and to the water transport line between said misting nozzle and said post-pumping heat exchanger for sensing water temperature of said high-pressure refrigerated water, said controller deactuating said compressor when said water temperature sensed by said water temperature sensor is below a predetermined target water temperature. 12. The system of claim 2, wherein said system controller is releasably operatively connectable to an enclosure temperature sensor disposed within said enclosure for sensing an enclosure temperature thereof, said system controller deactuating said compressor and said pump when said enclosure temperature sensor senses that said enclosure temperature is below a predetermined target enclosure temperature. 13.
