refrigerating loss

An ejector should be adopted in some low cooling-capacity refrigerating systems instead of a throttle valve to recover some high-pressure potential power and reduce the irreversible energy loss of throttle process for improving the energy efficiency ratio ( EER) of the CO_2 system.

为减小CO2跨临界循环系统节流部分的膨胀功损失，提高系统性能，可在小型制冷系统中采用喷射器代替节流阀，部分回收工质从高压到低压过程的膨胀功。

Improves calculation method of insulation course thickness within maximal refrigerating loss specified in coherent norm. The allowable maximum heat loss prescribed in the national standard is taken as a basic reference by many other related standards.

改进了最大允许冷损失下保冷层厚度的计算方法。国家标准《设备及管道保温技术通则》中规定的允许最大散热损失值被多个相关标准引用。
