太阳能吸收制冷循环动态特性仿真方法研究
Research on dynamic simulation methods for solar-powered absorption refrigeration cycles
摘要
Abstract
The solar-powered absorption refrigeration cycle is plagued by inherent deficiencies,such as poor performance and potential operational failures,especially under varying conditions.Although solar-powered absorption refrigeration stands as a nearly electricity-free refrigeration technology,its operational performance is significantly hindered by the intermittent nature of solar energy and fluctuating user demands.From the perspective of internally matching parameters with external conditions,a state-space model for a solar-powered single-effect LiBr-H2 O absorption refrigeration cycle is established based on modern control theory.This dynamic model of the solar-powered absorption refrigeration cycle has been validated through steady-state simulations and experimental results,and its dynamic response characteristics have been evaluated under various disturbances.The findings suggest that the state-space dynamic model not only captures the dynamic characteristics of the solar-powered absorption refrigeration cycle but also elucidates the dynamic relationships among input variables,state variables,and output variables.关键词
