The investigation of the (p,rho,T) and (P_s,rho_s,T_s) properties of {(1-x)CH_3OH+xLiBr} for the application in absorption refrigeration machines and heat pumps

摘要

The (p,rho,T) and (P_s,rho_s,T_s) properties of {(1-x)CH_3OH+xLiBr} over a wide range of state parameters are reported for the first time.The experiments were carried out in a constant volume piezometer over a temperature range from 298.15 K to 398.15 K,at 0.08421,0.13617,0.19692,0.23133 and 0.26891 mole fractions and from atmospheric pressure up to 60 Mpa.The experimental uncertainties are DELTAT=+-3 mK for temperature,DELT_p=+-5·10~(-2) MPa for high pressure and DELTA_p=+-5·10~(-4) MPa for atmospheric pressure,DELTA_p=+-3·10~(-2)kg·m~(-3) for density.An equation of state was derived for correlation for the experimental data of the solutions.
