【摘要】：以Kalina地?zé)岚l(fā)電循環(huán)(KCS11)為研究對(duì)象,針對(duì)冷熱源溫度、工質(zhì)濃度比及循環(huán)壓力等參數(shù)的變化對(duì)KCS11循環(huán)效率的影響進(jìn)行研究�；贓ngineering Equation Solver(EES)工程軟件平臺(tái),編寫(xiě)KCS11運(yùn)行參數(shù)的計(jì)算模型。模擬結(jié)果與文獻(xiàn)中的數(shù)據(jù)進(jìn)行對(duì)比,擬合程度較好。進(jìn)一步研究表明,系統(tǒng)運(yùn)行中氨水濃度應(yīng)略高于最高效率點(diǎn)所對(duì)應(yīng)的濃度值,且系統(tǒng)壓力應(yīng)等于或略大于最高效率所對(duì)應(yīng)的壓力值。通過(guò)對(duì)冷熱源溫度、濃度、壓力等參數(shù)分析,熱源溫度升高或冷源溫度降低10℃,系統(tǒng)循環(huán)效率可提高2.0%~3.5%。在特定冷熱源溫度下,當(dāng)氨水濃度增加0.10,循環(huán)最大效率所對(duì)應(yīng)的壓力增大0.8 MPa,系統(tǒng)泵耗隨之增加,故系統(tǒng)效率存在極值點(diǎn)。因此在系統(tǒng)運(yùn)行中應(yīng)考慮氨水濃度與系統(tǒng)壓力的匹配,保證系統(tǒng)能夠高效運(yùn)行。
