A new method based on the thermodynamic approach is presented for the separation of energy costs in the combined production of heat and cold. Relations are given for calculating the coefficients of performance for cooling and heating in the combined mode.

Keywords: coefficient of performance, combined production of heat and cold, costsharing, thermodynamic method
