Abstract
The invention relates to a flow ice making method and device based on lithium bromide absorption type refrigeration cycle. A lithium bromide concentrated solution continuously absorbs steam in an absorber for causing a low-pressure environment of an evaporated refrigerating chamber; water is continuously evaporated for absorbing self heat in the low-pressure environment of an evaporated refrigerating chamber to be partially frozen into flow ice. After the lithium bromide solution absorbs steam derived from the evaporated refrigerating chamber in the absorber and is diluted, the lithium bromide solution is conveyed to a generator by a solution pump for being heated and regenerated; the concentration of the solution is improved, and the solution has the moisture absorbing ability again; and then, the solution is cooled and conveyed to the absorber to form solution absorbing-regenerating recirculation. The steam derived from the generator is condensed into subcooled water in a condenser; and after being throttled, the subcooled water is conveyed to the evaporated refrigerating chamber for making ice. An ice making system is automatically supplemented by a water tank according to the water level of the evaporated refrigerating chamber.
