PROBLEM TO BE SOLVED: To provide a heat transfer composition having excellent heat transfer characteristics, and characteristics such as chemical stability, low toxicity or non-toxicity, incombustibility and compatibility with lubricants. SOLUTION: The heat transfer composition is expressed by chemical formula (1): XCF z R 3-z (wherein X represents a 2-3C unsaturated substituted or non-substituted alkyl group; R independently represents Cl, F, Br, I or H; and z represents 1-3). The composition contains at least one fluoroalkene and has ≤ about 150 global warming potential (GWP). These materials are generally useful as refrigerants for heating and cooling, foaming agents, aerosol propellants, solvent compositions, and fire extinguishing and suppressing agents.
