COMPOSITION CONTAINING COMBUSTIBLE REFRIGERANT

The present invention addresses the problem of providing a composition containing a combustible refrigerant, the composition having decreased combustibility, wherein the refrigeration capacity is sufficiently maintained compared to when only the combustible refrigerant is used. Provided is a composition containing (a) a combustible refrigerant; and (b) at least one organic compound selected from the group consisting of halogenated hydrocarbons respectively represented by the following general formulae: CFnW(4-n) (the W's are identical or different and represent Cl, Br, or I, and n represents 1or 2; and the case in which n is 2 and the W's are all Cl and the case in which n is 2 and the W's are all Br are excluded); CF3CX3 (the X's are identical or different and represent F, Cl, Br, or I;and the case in which the X's are all F is excluded); CF3CF2CY3 (the Y's are identical or different and represent F, Cl, Br, or I; and the case in which the Y's are all F is excluded); and CF3CF2CF2CZ3 (the Z's are identical o
