CO_2跨临界循环中气体冷却器的熵产分析

Entropy generation analysis of gas cooler in CO_2 trans-critical cycle

指出CO2跨临界制冷循环中的放热设备是气体冷却器,CO2在整个放热中并无相变,其状态主要是超临界流体,针对超临界流体的特殊性质,用熵产分析研究气体冷却器的换热问题;在此基础上,提出了气体冷却器优化设计的原则与方法。

The paper points out the heat release equipment in the CO2 trans-critical cycle is the gas cooler, and the CO2 has no phase change in the process of heat releasing, its main state is the supercritical fluid, aiming at the special characteristics of the supercritical fluid, studies the heat changing problems the gas cooler based the entropy generation analysis, on this basis, provides the principle and method of gas cooler optimization design.
