FIELD: instrument engineering. SUBSTANCE: pressure-increasing device has gasified vessel with thin-walled cup positioned in it, tank with cooling agent, and heat exchanger installed in heat-insulating casing along with pipelines and fittings. Heat exchanger is positioned inside thin-walled cup. It communicates with tank containing cooling agent during period of working medium condensation (freezing) through lowering and lifting tubes. Within gasification period heat exchanger communicates with heating gas line. Lower edge of heat-exchanger surface of external heat exchanger is deepened with respect to bottom of thin-walled cup for distance h = (0.6-0.8)l, where l is heat-exchanging surface height. The device makes it possible to reduce time of operation cycle. EFFECT: reduced cooling agent and heating gas consumption. 1 dwg
