比环境温度低的物质所具有的吸收热量的能力,称为有一定冷量,这种低温的获得是花费了一定的代价——压缩气体消耗功,将气体压缩后再进行膨胀获得的。如果这部分冷量未能加以回收利用,则称为冷量损失。
管道附件、阀门、支撑等引起的附加冷量损失系数。
The additional cool losing produced by the appendix, such as values, brace etc.
介绍了区域供冷系统二次管网的冷量损失及冷量损失导致的温升的计算方法,并对某个二次泵变流量运行的区域供冷系统进行了计算。
Presents the calculation method of cooling loss and temperature rising caused by cooling loss of the variable water flow secondary piping network in district cooling system(DCS).
在能量转移系统中,应该采用容积膨胀减压方式减少减压环节的可用能损失;合理利用低温排气的冷量火用可以提高气动发动机能量转移系统的总能量效率。
The expander can reduce exergy loss in pressure reducing process, and the utilization of cryogenic exergy of air-powered engine exhaust is useful to improve the total energy efficiency.
