Abstract
A working medium including HFO-1123, HFO-1234yf, and carbon dioxide, wherein X and Y satisfy the following Inequalities (A1) and (A2): (A1) −2.20X+25.60≤Y≤−5.58X+61.74, (A2) 2.5≤X≤6.0, in which the content of the carbon dioxide with respect to the total content of these components is defined as X % by mass, and the content of HFO-1123 with respect thereto is defined as Y % by mass, and in which the total content of HFO-1123, HFO-1234yf and carbon dioxide is 99.0% by mass or more with respect to the total amount of the working medium; and a composition for a heat cycle system, a heat cycle system and a heat cycle method using the working medium, are provided.
