ABSTRACT:
The invention deals with a process for the energy-saving automatic control of the concentration of evaporating coolant mixtures, especially of water-containing ammonia solutions in evaporators of refrigerating machines and heat pumps based on the absorption principle, together with different embodiments for carrying out the process. The process makes possible the combined utilization of the vaporization potential of the solution outflow and the cooling potential of the cold vapor withdrawn for subcooling the condensate feed, while selecting the minimum temperature difference between the subcooled not-yet-depressurized condensate feed and the boiling coolant mixture in the evaporator as the control variable for process automatization. This temperature difference is independent of the saturation pressure of the boiling coolant mixture and can be maintained constant for every evaporator load point to obtain an energy-saving solution outflow. Finally, the concentration of the boiling coolant mixture is maintained with this procedure, and the evaporator operates for every evaporation temperature with the highest possible saturation pressure, almost like a single-substance evaporator.
