| 摘 要： | 从热力学观点讨论了工作温度对于制冷循环系统性能的影响。分析了与循环时间有关的温度效率和熵产数。对于一个相对较短的循环时间,吸收/解吸收热量转换器的温度效率在200秒后可以达到92%。熵产数Ns由在一个循环系统内生成的不可逆性参数和热量转换器流体有效性参数之间的比率决定。结果显示,在使用一个30℃冷源的情况下高级吸收式循环系统的熵产数Ns在热水温度是45℃至55℃之间时是相对较小的,而对于传统循环,在使用相同冷源温度的情况下,热水温度在65℃到75℃之间时,Ns是相对较小的。

| Abstract: | This paper discussed the working temperature influence on refrigeration cycle system performance from thermodynamics.The temperature efficiency and the entropy generation related with cycle time were analyzed.Regarding relatively short cycle time,Absorption/desorption endothermic quantity switch's temperature efficiency could reach 92% in 200 seconds later.The entropy generation Ns is defined by ratio between irreversibility parameter and thermal switch fluid valid parameter in a refrigeration cycle system.... |
