<P>PROBLEM TO BE SOLVED: To provide a cooling system or the like having a new helical pipe type velocity-heat converter using a clean multi-component refrigerant or the like that causes no environmental pollution. <P>SOLUTION: The cooling system employs a multi-component heat medium produced by combining and mixing two or more kinds of heat mediums having different properties. A plurality of helical pipes 31, 32, and 33 dedicated for velocity-heat conversion for each of heat medium components having different properties are provided in multiple stages. Optimum liquefaction/cooling conditions are established for each of the heat medium components having different properties inside each of the helical pipes 31, 32 and 33. The heat medium components are almost completely liquefied and decompressed/cooled. <P>COPYRIGHT: (C)2013,JPO&INPIT |
