R134a-DMF吸收式热泵系统动态建模仿真与特性分析
Establishment and simulation study of dynamic mathematical model for R134a-DMF absorption heat pump
摘要
Abstract
The development of a new R134a-DMF working pair absorption heat pump system can better utilize low-temperature heat sources and is safer and more environmentally friendly compared to other working pair systems.However,the dynamic heat transfer mechanism of absorption heat pump systems remain insufficiently understood,and existing dynamic modeling approaches,which are largely based on steady-state assumptions,making it difficult to accurately capture system performance under transient disturbances.In this study,a distributed dynamic modelwas developed in MATLAB to investigate the effects of heat-source temperature,chilled-water temperature,and cooling-air temperature on the performance of R134a-DMF absorption heat pump system.The dynamic heat-transfer characteristics of key components and the transient response behavior of the overall system were systematically analyzed.The results show that a 12.5%increase in heat-source temperature significantly increases the heat transfer of the condenser and evaporator,raising the coefficient of performance(COP)by 44%;while a 33%increase in cooling air temperature and a 14.3%decrease in chilled water temperature reduce the evaporator heat-transfer capacity,leading to COP to decrease by 22%and 10%respectively;and the response time of the generator under the above operating conditions is within 4～23 min.关键词
