The present invention provides a heat transfer composition having excellent heat transfer characteristics, chemical stability, low toxicity or non-toxicity, non-flammability, and lubricant compatibility. A heat transfer composition comprising at least one fluoroalkene represented by the chemical formula (1) having a global warming potential (GWP) of about 150 or less. XCF Z R 3-Z (1) (Wherein X is an unsaturated substituted or unsubstituted alkyl group having 2 or 3 carbon atoms, R is independently Cl, F, Br, I, or H, and z is 1 to 3) Is) These materials are generally useful as refrigerants for heating and cooling, blowing agents, aerosol propellants, solvent compositions, and fire extinguishing and extinguishing agents.
