夏热冬暖地区蒸发式全热回收新风机组设计能效计算方法探讨OA
Energy-Saving Evaluation Method and Calculation Discussion of Evaporative Total Heat Recovery Fresh Air Units in Hot-Summer and Warm-Winter Regions
以自带冷源蒸发式全热回收新风机组为研究对象,提出其能效计算模型与能效比计算方法.以广州某超高层办公楼采用的该类型新风机组为例,计算四种典型风量新风机组能效比.结果表明:在夏季全热回收效率取60％,送风处理到室内空气等焓点工况下,新风机组能效比均在4.3左右.计算结果可为工程设计人员在前期设计阶段合理选择该类型机组提供参考.
Taking the evaporative total heat recovery fresh air unit as the research object,and its energy efficiency calculation model and calculation method for energy efficiency ratio are proposed.Taking a super high-rise office building in Guangzhou which uses this type of fresh air unit as an example,the energy efficiency ratio of typical air volumes are calculated.The results show that,when the total heat recovery efficiency is 60％in summer and the supply air is processed to the same enthalpy value as the indoor air,,the energy efficiency ratio of the fresh air handling unit is around 4.3.The calculation results can provide a reference for engineering designers to reasonably select this type of fresh air unit in the early design stage.
