太阳能变效吸收式制冷系统动态运行特性研究
Study on Dynamic Operating Characteristics of Solar Variable-Effect Absorption Refrigeration System
摘要
Abstract
A dynamic model is developed for LiBr/H₂O variable-effect absorption refrigeration systems(VARS)and constructs an XGBoost model for efficient optimization of dual free parameters,with coefficients of determination reaching 0.92 and 0.99,respectively.Model validation against steady-state and dynamic experimental data confirmed average errors below 5%.The model successfully characterizes VARS transient responses to heat source step disturbances and enables full-time solar operation simulations with linear Fresnel collectors.The results demonstrate an average coefficient of performance of 0.96 for VARS during peak cooling under typical Shanghai summer weather conditions,with the solar cooling system reaching 0.47.关键词
