Thermodynamic properties of aqueous ternary solutions relevant to chemical heat pumps: Final report. [LiNO/sub 3/-KNO/sub 3/-NaNO/sub 3/]

OSTI ID:6730888
Polynomial expressions are developed that correlate experimental vapor-liquid-equilibrium (VLE) and specific enthalpy concentration data for a newly developed ternary absorption fluid (LiNO/sub 3/-KNO/sub 3/-NaNO/sub 3/). The development of these expressions are an important step toward using existing ORNL computer software to evaluate heat pump performance. A canned least-square-fit program, POLFIT.BAS, was invoked to obtain the polynomial coefficients. Results show that the maximum deviation between correlated and actual values is less than 3% for vapor pressure and enthalpy. This is considered sufficiently accurate for heat pump cycle performance studies.
