Energy saving amount calculation and control method of outdoor air energy recovery system in public buildings

Combining with the relevant provisions of the Design standard for energy efficiency of public buildings (GB 50189—2015), gives the analysis and calculation method of the annual energy saving amount of outdoor air energy recovery systems. Taking a hotel building and an office building in Beijing as examples, discusses the energy saving effects of outdoor air energy recovery systems under four control modes, and gives the annual energy saving amount per unit outdoor air volume in different application forms, which provide references for related engineers to determine whether it is worth to use the energy recovery system, and which form and which control mode of energy recovery systems should be used in outdoor air systems.
