SECONDARY COOLING MEDIUM FOR SECONDARY CIRCULATION COOLING SYSTEM, AND SECONDARY CIRCULATION COOLING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a secondary cooling medium for a secondary circulation cooling system, which is incombustible and has a small environmental load, a small pressure loss, and a high heat transfer coefficient, and to provide the secondary circulation cooling system in which the secondary cooling medium for the secondary circulation cooling system is used.;SOLUTION: The secondary cooling medium for the secondary circulation cooling system contains 1,1-dichloro-2,3,3,3-tetrafluoropropene. The secondary circulation cooling system 1 has: primary cooling means 10 for cooling a primary cooling medium 42; secondary circulation cooling means 12 for circulating a secondary cooling medium 44 to cool an object 46 to be cooled; and a heat exchanger 14 for performing heat exchange between the primary cooling medium 42 and the secondary cooling medium 44 to cool the secondary cooling medium 44. The secondary cooling medium 44 is the secondary cooling medium for the secondary circulation cooling system.;COPYRIGHT: (C)2014,JPO&INPIT
