Based on the general ventilation equation of industrial ventilation, obtains the indoor air humidity ratio model by the analogical method. When the office building with temperature & humidity independent processed air conditioning system is not occupied, outdoor air moisture load by infiltration is the main source of indoor moisture load. Based on a case, compares the theoretical calculation results of the model and the simulation results of Fluent software, and verifies the practicability of the humidity ratio model. Determines the suitable outdoor air requirement per capita and the pre-dehumidification time of outdoor air under different outdoor air humidity ratios using the model, which is favorable to carry out optimal operation of outdoor air handling units for temperature & humidity independent processed air conditioning systems.
