摘　　要：本文以焓差法作为判断依据,得出商业内区全空气系统在全年运行过程中可能存在的几种运行工况,并给出了系统全年运行能耗的计算方法。通过全年能耗和初投资计算,从系统设计使用周期内经济性最优的角度,得出全空气空调系统的送风量及送风温差的确定方法,为商业内区的空调系统的设计选型提供依据和参考。Based on the enthalpy difference method, this paper obtains several possible operating conditions of the all air system in the commercial inner district during the whole year’s operation, and gives the calculation method of the whole year’s operation energy consumption. By calculating the annual energy consumption and initial investment, and from the point of view of optimum economy in the design and use period of the system, the determination method of air supply volume and air supply temperature difference of the whole air conditioning system is obtained, which provides the basis and reference for the design and selection of air conditioning system in the commercial inner district.
