Problems solved by technology
[0003] During the operation of the central air conditioner, since the cooling load of the building changes dynamically, and the cold source equipment of the central air conditioner in the prior art cannot be dynamically optimized and adjusted accordingly, the energy efficiency of the cold source system of the central air conditioner is generally low. And there is a certain waste of energy

The invention discloses a central air-conditioning system modeling and energy efficiency optimizing method and device. The central air-conditioning system modeling and energy efficiency optimizing method comprises the steps of selecting corresponding fitting models according to the type and amount of collected data, saving and preprocessing the collected data, carrying out model fitting on the preprocessed data and the fitting models, establishing a cold source system simulation platform to analyze the influencing factors of the operation efficiency of a central air-conditioning cold source system, and obtaining the running conditions of the central air-conditioning cold source system and the energy consumption conditions of a refrigeration water pump, a cooling water pump, a water chillerand a cooling tower based on the optimization control, wherein the influencing factors include the inlet and outlet water temperature, flow rate and inlet and outlet water pressure difference corresponding to the refrigeration water pump, the cooling water pump, the water chiller and the cooling tower, and the outdoor temperature and humidity. The energy-saving potential of the central air-conditioning system can be fully tapped, the overall operation efficiency of the central air-conditioning system is improved, and the operation energy consumption of the central air-conditioning system is reduced.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning energy saving, and in particular relates to a central air-conditioning modeling and energy efficiency optimization method and device. Background technique [0002] With the continuous improvement of people's requirements for quality of life and living environment, air-conditioning systems for improving people's comfort are more and more widely used in various buildings. However, while air conditioning systems improve people's living standards, they also cause a large amount of energy consumption. According to statistics, the energy consumption per unit area of large public buildings in my country can reach 70-150kW·h / m2 per year. For large and medium-sized public buildings with central air-conditioning systems, the energy consumption of central air-conditioning systems accounts for more than 40% of the total energy consumption of the building, while the air-conditioning energy consumpt...
