FISH REFRIGERATOR UTILIZING LIQUID REFRIGERANT

摘要

Some pipes (3) with many jet-holes (2) are installed at the bottom of a tank (1) (e.g. in a ship (6) transporting fish). Many fish are put into such tank together with ice and water, and are stored while refrigerated. The pipes are connected to sources (5) (e.g. some bombs) feeding the liq. refrigerant (e.g. liq. nitrogen or liq. carbonic acid) through an evaporator (4) formed by a pipe bent zig- zag and fixed on side walls of the tank. The water and fish in the tank are kept at lower temp. while agitated by jetted refrigerant, evaporated in the evaporator, from jet-holes (2) of pipes (30).
