heal.abstract	The paper simulates the operation of a refrigeration system resulting by the combination of a LiBr/ZnBr2/CH3OH absorption unit (mole ratio Libr/ZnBr2 = 2:1) with a salt-gradient solar pond. The absorption unit receives heat from the solar pond at the available high temperature level and produces cooling rejecting the total amount of received heat to the ambient at an intermediate temperature level. The operation of the absorption unit is simulated by using analytic functions describing the thermodynamic properties of the LiBr/ZnBr2/CH3OH mixture, so that the exact thermodynamic cycle is calculated and plotted on the enthalpy-temperature plane. The simulation of the solar pond is based on a finite-difference solution of the transient one-dimensional heat conduction equation along the year. Application of the model developed is made by using available climatological data of the Athens area. Further, correlations are developed, which link climatological conditions with important characteristics of the solar pond and the absorption unit, under the condition of optimum operation during a specified period of time. These correlations may be employed for making a first estimation in the design of solar pond driven absorption refrigeration plants.	en
