Abstract
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.关键词
