The invention provides a working medium. The working medium comprises a refrigerant and a refrigerating machine oil combination. The refrigerant is the R32 refrigerant of 100% weight. The refrigerating machine oil combination comprises polyol ester and poly-alpha-olefin which are mixed according to a certain ratio. The invention further provides a refrigeration device applying the working medium. According to the working medium and the refrigeration device applying the same, the working medium comprises the R32 refrigerant and the refrigerating machine oil combination which is formed by mixing the polyol ester and the poly-alpha-olefin, thus the R32 refrigerant and the refrigerating machine oil combination have good intermiscibility, so that the separation temperature of the refrigerant and the refrigerating machine oil combination is lower than -30 DEG C, the problem that a compressor moving component lacks oil due to the fact that a refrigerant and refrigerating machine oil are liable to layering is solved,
