| Abstract: |
| The law of ventilation resistance balance along all circuits in a ventilation system are used to established the two adjustment models under the condition that air volumes of all branches meet reasonable requirements of engineering: one is the optimization model of assigning fans to make adjustment based on that the energy consumption of all fans arrives at minimum; the other is the optimization model of selecting optimum branches to install fans to make adjustment based on that the energy consumption of all fans arrives at minimum and the number of fans arrives at minimum also. In order to solve these models quickly, considering the requirement that circuit ventilation resistance balance in all circuits must be satisfied and the requirement that allocating air volumes by demand on some branches must be met also in the ventilation system, through linearization of constraints and special processing on allocating air volumes by demand, these optimization models are simplified. Based on the characteristics of the two optimization models, the two special solving methods based on the population dynamics-based optimization algorithm are put forward to solve the two optimization models. Results of application show that the optimization models can calculate in advance the influence after fans are installed, and can select the optimal positions, numbers and work parameters of fans. |
