The influence of the heat leakage the position of resonant center energy level and the width of energy level on the performance characteristics of the heat pump is discussed .

探讨了热漏、共振中心能级位置和 能级 宽度等参数对热泵工作性能的影响。

When the width of the resonance energy is large the maximum coefficient of performance increases as the width of energy level decreases .

共振能级宽度比较大时，热泵系数的最大值随着共振 能级 宽度的变小而增大。
