Abstract: A water cooling apparatus utilizes a conventional ice maker to produce ice which is deposited into a large insulated storage tank. The insulated storage tank includes a suspended grate to hold the deposited ice and spray nozzles positioned above the grate bathe the ice with water. Upon spraying, the ice suspended in the tank partially melts, combines with, and cools the sprayed water. A reservoir in the bottom of the tank collects the cooled water, and a sump pump in the bottom of the reservoir pumps water out of the storage tank to a distribution pump. The cooled water is further distributed under pressure to the fogging nozzles positioned in the enclosure's ventilation system. Sensors monitor the level of ice on the grate, the level of cooled water in the reservoir, and the temperature of the animal enclosure.
