Air conditioner chilled water supply temperature strategy identification method based on subitem metering data

Abstract

The invention provides an air conditioner chilled water supply temperature strategy identification method based on subitem metering data, and relates to the field of building air conditioner system operation strategy identification. According to the method, a parameter replacement method is adopted, the relation between chilled water supply temperature and relation parameters thereof is studied only through subitem metering energy consumption data and outdoor environment data, and the chilled water supply temperature is obtained through water chilling unit energy consumption, cooling tower energy consumption, chilled water pump energy consumption, cooling water pump energy consumption, outdoor dry-bulb temperature, indoor dry-bulb temperature and visitor flow rate parameters. According tothe method, a chilled water supply temperature strategy ELM classification model is constructed, a chilled water supply temperature strategy of an air conditioning system is reversely identified fromreal-time chilled water supply temperature relation parameter data through the model, the chilled water supply temperature parameter operation strategy of the air conditioning system is remotely monitored in real time, building air conditioning system operation strategy identification is perfected, and reliable basis is provided for building operation management work in cooperation with development of building energy-saving diagnosis work, so that energy conservation and consumption reduction are achieved.

Description

[0001] The invention relates to the field of operating strategy identification of building air-conditioning systems, in particular to a method for identifying the temperature strategy of air-conditioning chilled water supply based on sub-item metering data Background technique [0002] According to statistics, at present, the existing public buildings in my country can reach 4.5 billion square meters, of which large public buildings using central air conditioning are about 500-600 million square meters, and their power consumption per unit building area is 7-10 times that of residential buildings. my country's public buildings have been regarded as the focus of building energy conservation because of their great energy-saving potential and complex building functions. In the whole life cycle of buildings, 80% of the energy consumption is the energy consumption of buildings during use. However, existing public buildings in my country generally emphasize design and neglect operati...
