CO2-[emim][Tf2N]吸收-喷射CCHP性能研究
Study on the performance of CO2-[emim] [Tf2N] absorption-injection CCHP
摘要
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.关键词
