Research on Energy Efficiency Improvement Methods for Large-Scale Air Conditioning Systems Oriented to Multiple Scenarios

Energy consumption of central air conditioning is the main part of building energy consumption. Due to the immature control technology and business model of the central air conditioning system, unnecessary waste is caused in the operation process. Therefore, there is still much room to improve the energy consumption of the central air conditioning system. For this reason, the energy efficiency improvement method of large-scale air-conditioning system for multiple scenarios is studied in this paper, the simulation model of air-conditioning load characteristics in multiple scenarios is researched, and the adjustable capacity of air-conditioning load in different scenarios is summarized. In addition, the scheme of air conditioning load participating in power grid regulation is formulated. Combined with the characteristics of air conditioning load, the appropriate data is selected to predict the air conditioning system load, and the adjustable capacity of air conditioning load is obtained. Finally, according to the results of load forecasting and adjustable capacity of air conditioning load, the scheme of air conditioning load participating in power grid managing is formulated.
