Abstract

Abstract To maximize energy use, this paper designs a lithium bromide absorption refrigeration system that is used to recycle and use low-temperature energy and industrial residual heat. Firstly, the mathematical model of the system is established using the lithium bromide aqueous solution status equation and the equation of the state of water and steam to obtain the state parameters in the thermodynamic calculation process of the system. Secondly, according to the principle of mass economy, energy saving, and heat transfer, the thermodynamic parameters of each process of the system are obtained to assist the design of the system. Finally, the influence of some key parameters on the system is simulated and analyzed to obtain the optimal parameters which can make the system recovery efficiency the highest. The simulation results show that the system conceived in this article can efficiently recycle waste gas and achieve the purpose of refrigeration. Therefore, it has a certain value of popularization.
