First of all, on the basis of energy analysis software EnergyPlus, the building structure of the office building, air conditioning, cooling and heating source system energy consumption models are established, respectively, through the exploration and the measured data of the model calibration, and achieve ASHRAE Guideline 14-2012 guide to the accuracy requirement of the energy consumption model calibration. Secondly, based on the calibrated energy consumption model, different adjustment strategies are simulated. With actual operating data analysis results show that through water chiller sets group control adjustment, water pump frequency conversion adjustment and fresh air system control adjustment, can respectively reduce water chillers, pumps and air unit energy consumption by 26%, 3% and 1%. Finally, this paper summarizes the significance and necessity of building air-conditioning system adjustment, and provides a basis for future project adjustment.
