It has been pointed out that chlorine has a long lifespan and diffuses into the stratosphere, where it is decomposed by sunlight and generated chlorine radicals that cause a chain reaction with ozone and destroy the ozone layer. Therefore, in place of these conventionally used fully halogenated hydrocarbons, active efforts are being made to find alternative substances that are less likely to deplete the ozone layer. As an alternative substance that does not destroy the ozone layer, R224d a is disclosed in Japanese Patent Application Laid-Open No. 58-37077.

The present invention reduces the amount of conventional fully halogenated hydrocarbons used, and creates a new material that has the excellent properties of stability, high efficiency, and nonflammability, and can be used as a substitute. The object of the present invention is to provide a working medium composition.
