Embodiment 1

[0045] The invention provides a multi-dimensional evaluation method of energy efficiency, comprising the following steps:

[0046] Step (1) Obtain relevant historical data of the system, and calculate energy consumption indicators and thermal comfort indicators based on the relevant historical data, and obtain a sample library of energy efficiency evaluation feature quantities;

[0047] The energy consumption index is the cold and heat load index per unit area of ​​the terminal building; the thermal comfort index is the estimated average thermal sensation index. Preferably, the thermal comfort index is divided into 7 grades, which are heat (- 3), Warm (-2), Warm (-1), Moderate (0), Cool (1), Cool (2) and Cold (3);

[0048] The index formula of the thermal comfort index in the prior art is:

[0049] PMV=[0.303exp(-0.036M)+0.0275]L

[0050] L={M-W-3.05*10 -3 [5733-6.99(M-W)-p a ]-0.42[(M-W)-58.15]-1.7*10 -5 M(5867-p a )-0.0014M (34-t a )-3.96*10 -8 f cl [(t cl +273) 4...

Abstract

The invention discloses an energy efficiency multi-dimensional evaluation method, device and system. The method comprises the steps that firstly, a sample library of energy efficiency evaluation characteristic quantities based on energy consumption indexes and thermal comfort indexes is established, a typical characteristic set is obtained through clustering analysis, and on the basis, a fuzzy pattern recognition method is adopted to intelligently match an energy efficiency characteristic vector to be evaluated with the typical characteristic set. Through the method provided by the invention,the thermal comfort of the terminal building passengers can be evaluated in real time, meanwhile, the influence of factors such as climate and airport scale on the terminal building energy consumptionis comprehensively reflected, the multi-dimensional comprehensive objective evaluation on the terminal building energy efficiency is realized, and the terminal building system energy consumption is reduced while the comfort of the passengers is ensured.

Description

technical field [0001] The invention belongs to the technical field of energy efficiency monitoring and evaluation, and in particular relates to an energy efficiency multi-dimensional evaluation method, device and system, which are suitable for airport terminal buildings. Background technique [0002] With the rapid development of the civil aviation industry, the scale of the terminal building is getting bigger and bigger, the structure is more and more complex, and its energy consumption is also increasing day by day, accounting for more than 50% of the total energy consumption of the airport. Attracted attention, some airports have established terminal energy efficiency monitoring systems to monitor energy consumption indicators in real time. [0003] As a large public place, the building energy consumption of the terminal building is mainly due to the creation of a suitable indoor heat and humidity environment to improve the comfort of passengers. Therefore, it is impossi...
