Abstract
The experimental results of a water purification system of single effect evaporation integrated into a heat transformer of 700 W are presented, using lithium bromide water as solution. It is demonstrated that it is possible to increase efficiency of energy use with heat recycling of a water purification system. The typical coefficients of performance values were increased from 24.7% to 30.3%, obtaining a maximum of 684 mL/h of distilled water. The behavior of the coefficient of performance in function of the absorber temperatures before and after the purification process is showed. Experimental and simulated data with the water purification system integrated into a heat transformer are analyzed.
