ABSTRACT:
The present method may be employed to reduce the temperature of water including chilling or freezing the water to produce ice and slush and simultaneously therewith keeping the water in motion, as from one container to another, without the use of a circulating pump. Liquid carbon dioxide is used as an expendable refrigerant by releasing same continuously beneath the water and then the activity of the conversion of the carbon dioxide changing from a liquid to a solid and gas is applied in a confined space to circulate the water as a liquid heat exchange medium.
The basic apparatus comprises a large container of water in which are one or more conduits or stacks at the bottom of which are holes admitting the water to be chilled. A CO.sub.2 nozzle receives liquid CO.sub.2 and a pressurized supply tank discharges the CO.sub.2 as a solid and gas through the nozzle which receives the CO.sub.2 as a liquid and the release into the confined area pushes the fluid through the conduits or stacks thereby circulating same in a tank to reduce the temperature and to keep the fluid in motion.
