Wirr Minus w irreversible, this is the work which is done to the environment by the system, -Wrev minus w irreversible is always smaller than minus w reversible.
一点提示，不可逆过程中系统,对外界做的功，总是小于,之前我们。
The energy available for doing work and irreversible loss are quantified by the availability balance, and compared with First Law energy balance. A parameter study is carried out.
通过各过程的能量可用性平衡分析，定量地计算了能量作功能力和不可逆损失，并且与热力学第一定律的能量平衡进行了比较；
Result shows that additional compressor work is needed due to the irreversible entropy productions in the rotary valve thereby decrease the COP of GM type PTC.
结果发现，由于气体在旋转阀中的不可逆损失，使得压缩机功耗增大，降低了GM型脉冲管制冷机的COP。
