Method for determining reference values of energy consumed by different items of large-sized public buildings

Abstract

The invention discloses a method for determining reference values of energy consumed by different items of large-sized public buildings, which includes firstly, obtaining different functional areas of a public building by calculating, and determining energy consumption indexes of the different functional areas of the public building, wherein the reference energy consumption value includes total building energy consumption, building lighting, building air-conditioning energy consumption and building air-conditioning different item energy consumption, and the building air-conditioning different item energy consumption comprises a cold source, a refrigerating unit, a refrigerating pump, a heating pump, a cooling pump, a cooling tower, an air-conditioner terminal and the like; secondly, calculating a deviation value k between energy consumption practical value and reference value, judging whether the deviation value k is larger than or equal to the constant C, wherein k=(practical value-reference value)/reference value*100%, if the deviation value k is larger than or equal to the constant C, building energy saving potential is great, and building energy saving potential analysis is required. The method is applicable to determining reference values of energy consumed by different items of different types of public buildings including hotels, offices, shopping malls and multifunctional buildings.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to a method for determining reference values ​​of sub-item energy consumption of large public buildings. Background technique [0002] There are many types of public buildings, and the functional uses of different types of public buildings, such as shopping malls, offices, hotels, etc., have large differences in energy consumption. Especially in big cities, there are a large number of comprehensive public buildings, which often have functional areas such as shopping malls, offices, and hotels at the same time. It is difficult to compare energy consumption horizontally. At present, the determination method of energy reference value for different types of public buildings and comprehensive public buildings with multi-functional areas is still blank in China, and it is impossible to judge whether comprehensive public buildings have energy-saving potent...

Problems solved by technology

Especially in big cities, there are a large number of comprehensive public buildings, which often have functional areas such as shopping malls, offices, and hotels at the same time. Difficulty in horizontal comparison of energy consumption levels

At present, the determination method of energy reference value for different types of public buildings and comprehensive public buildings with multi-functional areas is still blank in China, and it is impossible to judge whether comprehensive public buildings have energy-saving potential. Therefore, it is necessary to study The determination method of energy consumption reference value based on different functional areas of buildings is obtained, so that according to the energy consumption characteristics of different functional areas, the energy consumption of various types of large public buildings can be diagnosed and analyzed, the energy-saving potential of buildings can be tapped, and effective methods can be found. Energy-saving transformation technology, truly achieve the purpose of energy saving
