の利点がある。[Effects of the invention] The fluorinated hydrocarbon composition of the present invention is nonflammable and satisfies the excellent properties of conventional fluorocarbons while reducing the amount of fluorocarbons used, and has an azeotropic point. Therefore, it has the advantage that there is no change in composition during recycling, it can be used in the same way as conventional single fluorocarbons, and it does not require major changes to conventional technology.
