FIELD: technological processes.
SUBSTANCE: installation for obtaining melt water, the source of which is water ice obtained by utilization of the cold of liquefied natural gas, contains two pairs of successive heat exchangers with heat transfer surfaces, which are formed by a series of corrugated panels with channels for liquefied natural gas, water supply valves to heat exchangers, valves for supplying liquefied natural gas to the channels of heat transfer panels for freezing water and valves for supplying heating gas to the channels of the heat transfer panels to control the switching of the respective pair of heat exchangers from the ice-freezing mode to the melting mode.
EFFECT: use of this unit allows the use of part of the water to be cooled on the outer surface of the panels and then obtained from the heated ice melt water by cooling the panels by utilizing the cold of the liquefied gas.
