Abstract: The simulation of the air-conditioning system and the optimized control of minimizing the energy consumption under the constraint of temperature are mainly studied. The simulation software HVACSIM+ for air-conditioning systems is introduced. The air handling unit and the rooms of the first floor of one building are taken as the simulation target; a simulation system is set up based on the platform of HVACSIM+. The function describing the relation between the consumption of cooling coil and the chilled water velocity is found and taken as the objective function, and with improved cyclic variable method the controller’s parameters are optimized under MATLAB environment. The HVACSIM+ simulator is run again to calculate the energy consumption supplied by the cooling source. Results show that the system runs steadily while the controller works with the optimal parameters and the energy consumption of the cooling coil is greatly reduced compared with working in non-optimized condition.
