Study On Modeling And Dynamic Simulation Of Lithium Bromide Absorption Heat Pump

Based on thorough grasping the working mechanism,the system composition,the work mass's physics parameters and heat transfer coefficient calculation of lithium bromide absorption heat pump,according to laws of mass conservation,energy conservation,momentum conservation,simulation algorithms of each part were developed with module modeling method.The influence of heater metal heat capacity release on heat transfer process was considered in this paper.In this foundation, according to the linking relationships among the parameter of each component in Lithium Bromide absorption heat pump,the entire process of real-time simulation model of the system was developed on LN simulation platform.Static characteristic to the design operating condition and dynamic characteristics to the disturbance operating conditions were simulated.The simulation results are analyzed and they show that the dynamic simulation models have excellent static characteristics and dynamic characteristics.
