Abstract

A direct contact ice generation device (100) for use in refrigeration, including load-shifted refrigeration. A traditional refrigerant in its liquid state is injected into a container (3) of coolant, where the coolant (2) is pure water or an aqueous solution. As it absorbs heat from the coolant, the refrigerant rises through the coolant and is converted to its gaseous state, in which state it is then pumped away from the coolant container (3), compressed (4) and condensed (6) back to a liquid state, and then reintroduced to the coolant container (3). The coolant is thereby cooled and converted to an ice/water slurry, which slurry is then stored (10) for future cooling use or is circulated immediately, either as a liquid/solid slurry or as a liquid (with the ice filtered out), to the areas to be refrigerated. To ensure adequate separation of the refrigerant from the coolant following the extraction of heat from the coolant, the refrigerant must have a low miscibility in water, low reactivity with respect to water, and have a vapor pressure that at 32°F is in the range of pressures traditionally found in refrigeration systems.
