| Abstract: |
| Since the operation efficiency of HVAC system is low and the operation performance of subsystems are commonly affected by each other, a multi-objective optimization method to improve the operation performance of entire HVAC system is proposed based on exergy analysis. The HVAC system of an airport terminal is chosen as the study object. Exergy analysis is applied to set up the productive structure of the HVAC system. According to the productive structure of the HVAC system, the HVAC system can be divided into three subsystems: cooling tower subsystem, chiller subsystem, and AHU subsystem. Based on the exergy models of three subsystems, MOPSO method is employed to search for the lowest exergy losses of three subsystems by optimizing the control sets of the HVAC system. A typical day test results show that the optimization method can obviously reduce the exergy losses of all three subsystems and the entire system compared with the original control. So the operation efficiency of the HVAC system can be improved by the multi-objective optimization method. |
