An indirect metering system for power consumption of terminal equipment in public building air-conditioning systems

Abstract

The invention relates to an indirect metering system for power consumption of terminal equipment of air-conditioning systems in public buildings, comprising: a public building information collection module for collecting building type and power distribution branch circuit information; Consumption data; terminal equipment energy consumption splitting module, used to receive building type, power distribution branch information and sub-item power consumption data, and mix power consumption data in lighting socket power consumption sub-item and / or power consumption sub-item The energy consumption of the terminal equipment of the air conditioning system is split out to obtain the energy consumption splitting result of the terminal equipment of the air conditioning system; the evaluation module of the energy consumption splitting result is used to receive the splitting result of the energy consumption The index evaluates the pros and cons of the energy consumption split results of the air-conditioning system terminal equipment. Compared with the prior art, the present invention makes the energy consumption of each equipment of the air-conditioning system clear and definite, and has the advantages of high degree of automation, strong practicability, and convenient implementation.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an indirect metering system for power consumption of terminal equipment of an air-conditioning system of a public building. Background technique [0002] Building energy consumption has accounted for 30% of the world's total energy consumption. U.S. building energy consumption accounted for 39.9% of the country's total energy consumption in 2008 and 41.3% in 2010, while commercial buildings alone accounted for 18%, of which 36% was consumed by air conditioning systems. In China, building energy consumption accounted for 23.4% of the national energy consumption in 2011, and it rose to 28% in 2012, among which the energy consumption density of public buildings is the highest. Heating and air conditioning energy consumption in China accounts for almost 60% of total building energy consumption. In the face of the energy crisis, building energy conservation has been increasing...

Problems solved by technology

This method has a serious shortcoming and an obstacle that is difficult to overcome at present. The shortcoming is that a large number of energy consumption collection devices need to be installed, the cost is high, and the project is cumbersome; the obstacle is that the power distribution system of the existing building has different items due to the spatial location. Confusion of energy consumption, the most prominent of which is that the terminal equipment of the air-conditioning system of the air-conditioning system is mixed in the power consumption sub-item of the lighting socket or the power consumption sub-item of the power consumption. Simple and direct measurement cannot be realized unless each end is installed with a A set of energy collection equipment

Therefore, it has caused difficulties for the further development of sub-item metering, and it is impossible to obtain clearly classified power consumption data, which has brought inconvenience to the energy efficiency diagnosis of the entire building and sub-item energy consumption, and even the fault diagnosis of equipment.
