Indirect measuring system for electricity consumption of end device of air conditioning system of public building

Abstract

The invention relates to an indirect measuring system for electricity consumption of an end device of an air conditioning system of a public building. The system comprises a public building information acquiring module for acquiring building type and distribution branch information, an electricity energy sub-item measuring module for acquiring the electricity consumption data of each sub-item, a end device energy consumption decomposing module for receiving the building type, distribution branch information and sub-item electricity consumption data as well as decomposing the air conditioning system end device mixed in the electricity consumption sub-item of a lighting socket and / or a power electricity consumption sub-item so as to obtain the electricity consumption dismounting result of the air conditioning system end device, and an energy consumption discomposing result evaluation module for receiving the energy consumption decomposing result of the air conditioning system end device and evaluating the advantages and disadvantages of the energy consumption decomposing result of the air conditioning system end system according to the preset evaluation indicators. Compared with the prior art, the system has the advantages that the energy consumption of each device can be clear; the automation degree is high; the practicability is high; the use is convenient.

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.
