<P>PROBLEM TO BE SOLVED: To provide a device for continuously increasing a pressure of low-pressure gas to a high pressure without using a heat-insulating compressor, in order to achieve a refrigerating cycle which operates with energy other than electric power in case of power supply shortage. <P>SOLUTION: A gas is heated by a heater 5 having a pressure container with a low-pressure gas inlet disposed at its lower portion and a high-pressure gas outlet disposed at its high portion, and a heating heat source. The gas reduced in weight, is raised to bring a negative pressure in the pressure container to continuously suck the low pressure gas into the heater. As a result, the pressure of the low-pressure gas can be continuously increased. Heating efficiency can be improved by heat exchange between a low-temperature refrigerant vapor and a high-temperature liquid refrigerant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
