PROBLEM TO BE SOLVED: To provide liquid compositions for use in compression refrigeration, air-conditioning and heat pump systems.SOLUTION: Liquid compositions are use in compression refrigeration, air-conditioning and heat pump systems. In the liquid compositions, a fluoroalkene contains from 3 to 4 carbon atoms and at least 1 but no more than 2 double bonds is combined with an effective amount to provide lubrication of an essentially miscible organic lubricant comprised of carbon, hydrogen and oxygen, and has a ratio of oxygen to carbon effective to provide a degree of miscibility with the fluoroalkene so that when up to 5 wt.% of lubricant is added to the fluoroalkene, the refrigerant has one liquid phase at at least one temperature between -40 and +70°C. Methods for producing refrigeration and heating with the fluoroalkenes, alone or in combination with the disclosed lubricants, are also disclosed. |
