Abstract
In a process for adsorption cooling/conditioning of rooms, working media are used which comprise saturated aqueous solutions of calcium salts with an added organic polyhydroxy compound. The working media are distinguished by high salt contents and low salt precipitation temperatures at very low water vapor partial pressures and are suitable for use in continuously operated adsorption/desorption cycles of adsorption cooling/conditioning systems having high coefficients of performance.
