Abstract :Equations for ideal vapour compression heat pump coefficient of performance insert ignore into journalissuearticles values(COPR); which contain two fit-parameters are reported in this work. These equations contain either temperature term alone or temperature and pressure terms as the only thermodynamic variableinsert ignore into journalissuearticles values(s);. The best equation gave error ≥5% over wide range of temperature-lift and for different working fluid types that include fluorocarbons, hydrocarbons and inorganic fluids. In these respects the equation performs better than the one-parameter models reported earlier.
