heal.abstract	The thermodynamic properties of the NH3/H2 gas mixture, namely the enthalpy, the specific volume of the mixture and the NH3 'partial pressure' can be presented in an enthalpy/mass fraction diagram as a function of the state conditions (temperature, mass fraction, total pressure) to facilitate the calculation of the evaporation of NH3 taking place in small absorption refrigeration units. A method and a computer program have been developed giving the desired quantities, starting from the corresponding data of the real components H2 and NH3 and using the method of the second virial coefficients. The relevant results are valid for a total pressure of 25 bar and temperatures between -40°C to +50°C. © 1987.	en
