查询词典 efficiency engineer

The model is used to calculate theoretical EERs of units with different design options. Afterwards a study is performed to determine the payback periods and life cycle costs corresponding to theoretically calculated EERs, which finds out technical feasibility is prior to other factors when establishing EESs for CACUs. Finally, new energy efficiency standards and energy efficiency grades for CACUs are presented based on the aforementioned researches.
