| 摘 要： | 为研究空气饱和程度对换热效果的影响,采用数值模拟方法,计算气体沿等温线、等焓线、等含湿量线向饱和线靠近的过程中全热交换量、"火积"耗散、"火积"耗散热阻、全热交换效率的变化情况。研究发现:气体沿着这三条线逐渐向饱和线靠近时其"火积"耗散热阻始终在减小,全热交换效率在增大。

| Abstract: | In order to investigate the influences of air saturability on the heat transfer effect, this paper uses the numerical simulation method to calculate the effect on total heat exchange, entransy dissipation, entransy dissipation thermal resistance and heat exchange efficiency when air changes delay isotherm, isenthalpic and isobume near the saturation line. It is found that when the gas changes along the three lines approach to the saturation line, the thermal dissipation of the entransy dissipation always decreases, and the total heat exchange efficiency increases. |
