转轮热回收计算方法及节能分析

以全年时段图的形式直观计算全国各典型地区转轮全年热回收的冷热量.通过计算,分析了不同地区转轮的节能效果以及经济效益,建立了转轮热回收计算模型.计算结果表明:转轮冬季回收能量多于夏季,热回收全热能量在我国分布为从南至北逐渐增多;在长江流域地区,冬夏季潜热回收能量相当;全热回收中,冬季高于夏季,约为夏季的2倍.基于全生命周期法,我国大部分地区转轮热回收的投资回收期均为6年以内.

Calculation Method and Energy Saving Analysis on Wheel Recycle

The total energy recovery has been calculated in the form of annual time chart. The rotary energy saving effects as well as the economical benefits in different areas have been analyzed through calculation. Calculation model of the rotary heat recovery has been created. The calculation results indicate that the energy recovery is greater in winter, the whole heat recovery in wheel systems are gradually increasing from the south region to north region in china. The latent energy recovery in the Yangtse River drainage area is equivalent in both winter and summer. While in terms of whole heat recovery the latent energy recovery in winter is approximately twice as large as that in summer. Based on whole-life cycle, the investment recovery periods of the rotary heat recovery are all less than 6 years in most areas in China.
