摘　　要：为了更好地分析以一维无限深方势阱中的粒子为工质的量子循环性能,建立了一个量子狄塞尔热泵循环模型,该模型以一维无限深方势阱中无相互作用的费米子为工质。导出了以压缩比为控制变量的循环性能系数的表达式,发现热泵的性能系数同时取决于压缩比和截止比。研究了性能系数与截止比之间的函数关系、泵热率与截止比之间的函数关系、无量纲泵热率与热泵循环的性能系数之间的函数关系,分析了循环性能与各性能参数之间的关系。结果表明:性能系数与无量纲泵热率都是截止比的单调函数,无量纲泵热率是性能系数的单调递增函数。To better analyze the performance of quantum cycles with particles confined to a one-dimensional infinite potential well,a quantum diesel heat pump model was established,in which working substance was composed of non-interacting fermions confined to a one-dimensional infinite potential well.The expression of cyclic coefficient of performance(COP)with compression ratio as control variable was derived,and it is found that the coefficient of performance of the quantum diesel heat pump depends on both compression and cut-off ratio.The functional relationships between COP and cut-off ratio,pump-heating load and cut-off ratio,dimensionless pump-heating load and coefficient of performance were explored.The relationship between cycle performance and performance parameter was analyzed.The results show that the COP and dimensionless heating load are both monotonie functions of cut-off ratio,and the dimensionless heating load is monotonically increasing function of COP.
