Description

technical field [0001] The invention relates to the field of building energy saving and fault diagnosis algorithms, in particular to a public building air conditioner energy efficiency diagnosis system based on power consumption data. Background technique [0002] In the face of the energy crisis, building energy conservation is increasingly valued by various countries, and the energy consumption of building air-conditioning systems accounts for a large proportion of building operation energy consumption. In addition, the air-conditioning system equipment is diverse and complex, and the design, construction and commissioning stages are slightly careless. Therefore, improving the energy efficiency level of building air-conditioning systems is an important measure to reduce building energy waste. [0003] The monitoring and diagnosis of the operating status of the building air-conditioning system can detect abnormal energy consumption in time, and help building managers take t...

AI Technical Summary

Problems solved by technology

Since the cooling and heating load of a building changes with the outdoor meteorological parameters, and the amount of cooling and heat output is related to the rated energy efficiency of the air-conditioning subsystem, therefore, without the cooling and heating data, it is impossible to obtain The energy efficiency status of the air conditioning system cannot be diagnosed
