摘要:
为解决当下有关低品位热驱动CO2吸收-喷射式冷热电联供(CCHP)系统研究较少的现状,基于能量守恒和质量守恒原理对工质对为CO2-[emim][Tf2N]的吸收-喷射式CCHP系统建立了相关热力学模型,使用模型计算了不同气体加热器热源入口温度、气体冷却器入口水温、余热回收器入口水温及喷射器背压下,系统的循环制冷量Qe膨胀机输出功Wexp、供热量Qhe制冷系数COP、热效率ηthm及(火用)效率ηexg的变化趋势.结果表明:随着气体加热器热源温度的升高,系统的Qe,ηthm,ηexg均升高;低气体冷却器入口水温及低余热回收器入口水温均有利于系统性能的提升;喷射器背压升高,系统的Qhe,Wexg,Qe均升高.
Abstract:
In order to solve the present situation that there are few researches about CO2-[emim] [Tf2N] absorptioninjection CCHP system driven by low-grade energy,based on the law of conservation of energy and conservation of mass,the thermodynamics model of CO2-[emim] [Tf2N] absorption-injectio cycle was established.Using the model,the changing tendency of the cycle cooling capacity of system Qe,the output power of the expansion machine Wexp,heat supply Qhe,cooling coefficient COP,thermal efficiency ηthm,exergy efficiency ηexg were calculated when the value of inlet temperature of the different gas heater,the inlet water temperature of the gas cooler,the inlet water temperature of the waste heat collector were different.The results showed that the Qe,ηthm and ηexg of the system increased with the increasing of the heat source temperature of the gas heater.The low inlet water temperature of the gas cooler and the low inlet water temperature of waste heat collector were all beneficial to the improvement of the system performance.Qhe,Wexp,Qe of system rose with the back pressure of injector increasing.
