Absorption air-conditioning system is a green air-conditioning system. With binary solution as the working fluid, the system performance is better with lower cost. To further improve the efficiency, an electrosorption method is proposed to regenerate the absorbent solution. Its principle is similar to capacitive deionization. The system with LiBr-CaCl2 has been confirmed in the improvement of performance, while the cost-effectiveness wasn’t ideal to satisfy the need of some cases. To solve this problem, the system with MgCl2-CaCl2 is proposed to analyze the enhancement in the cost-effectiveness. The theoretical and experimental results verify the advantage in the cost-effectiveness compared to the system with LiBr-CaCl2. Although the performance of the system with MgCl2-CaCl2 is lower than the other mixed solution, the actual COP could reach 1.9, which is still better than the system with single absorbents. Meanwhile, the energy recovery characteristic could further enhance the advantage in the improvement of performance for the system with LiBr-CaCl2 and make up the weakness of the system with MgCl2-CaCl2 solution. The exploration of higher energy recovery efficiency will further improve the competitiveness of the system.
