    摘要: 1. A liquid composition for use in compression refrigeration, air-conditioning and heat pump systems comprises:
    (A) a fluoroalkene containing from 2 to 5 carbon atoms and at least 1 but no more than 2 double bonds; and
    (B) an effective amount to provide lubrication of an essentially miscible organic lubricant comprised of carbon, hydrogen and oxygen and having a ratio of oxygen to carbon effective to provide a degree of miscibility with said fluoroalkene so that when up to five weight per cent of lubricant is added to said fluoroalkene the mixture has one liquid phase at at least one temperature between -40 and +70°C, wherein said organic lubricant is a polyalkylene glycol having a viscosity in the range from 20 to 200 centistokes at about 37°C.
