The Mathematical Model And Optimization Of The Lithium Bromide Absorption Chiller Operation Research

This article introduces the basic knowledge of the regional energy station system, emphatically introduces the advantages of the lithium bromide absorption chiller is distinguished from other chiller, Through The H2series steam double-effect lithium bromide absorption chiller mathematical modeling, describe the chillers characteristic parameters (cooling capacity, power consumption and the chiller running COP)and two external parameters (outlet temperature of cooling water, inlet temperature of chilled water) between the non-linear function relation. The application of mathematical models in practical engineering technical and economic analysis and optimal operation research. Which for energy consumption system management, the overall optimization of the engine running, the rational allocation of the chiller, room energy-saving operation to provide an effective analysis methods and means.By using the least squares fitting relative error and testing that this mathematical model has higher precision, agree with actual engineering application, can effectively used in construction equipment environment optimization simulation of water chiller.Combined with the actual operation of the project data for lithium bromide absorption chiller mathematical modeling, Including simulation calculation chillers’COP related parameters, the outside parameters under the premise of unchanged, chilled water outlet temperature rise per1, cooling capacity increased by4%-7%, lower input electric power, correspondingly larger COP value; Cooling water every1, cooling capacity decreased by5%-7%, the input power increases, and the COP value also gradually become smaller.Through the simulation chillers’COP with the change of the external parameters, draw a lithium bromide absorption chiller COP with chilled water outlet temperature rising and rising, changing with the cooling water inlet temperature rising and falling. Accordingly, can put forward by improving the lithium bromide chiller chilled water outlet temperature, reducing the inlet temperature of cooling water,the way such as Secondary pump variable flow are used to improve the chiller and the whole centralized energy station working performance.
