Energy-saving assessment system of central air-conditioning system

Abstract

The invention discloses an energy-saving assessment system of a central air-conditioning system. The energy-saving assessment system comprises a central air-conditioning system energy-saving analytical test platform, a power acquisition module, a temperature acquisition module, a flow acquisition module and a pressure acquisition module, wherein the power acquisition module, the temperature acquisition module, the flow acquisition module and the pressure acquisition module are respectively connected with the central air-conditioning system energy-saving analytical test platform, each module comprises a plurality of sensors corresponding to the module, and the sensors are arranged in areas where data need collecting. The system uses each gathering module to conduct dispersive data acquisition on the central air-conditioning system according to equipment distribution, uses a wired or wireless mode to upload the data to summarize, and accordingly achieves analytical test on energy-saving effects of central air-conditioning system. Each module of the system adopts the portable design and the easily-installed design, the energy-saving assessment system is simple in assembly, most central air-conditioning systems can be used, and the system is wide in generality. The system can conveniently conduct data acquisition on dispersive central air-conditioning system equipment located in buildings and solves problems of dispersive data acquisition and data summarization and uploading.

Description

technical field [0001] The invention belongs to the field of building energy management, and in particular relates to an energy-saving evaluation system of a building central air-conditioning system. Background technique [0002] The main energy consumption of buildings is concentrated in the load of the central air-conditioning system of the building. At present, my country is also vigorously promoting energy-saving buildings. A large number of energy-saving products and energy forms are applied in the central air-conditioning system of buildings. Due to the diversity and complexity of the schemes, it has become a technical problem to accurately assess the energy consumption and energy saving of a building or a region in a building in the central air-conditioning system. In the past, the intelligent statistics of the building's central air-conditioning system were mainly through the building automation system. (Building Automationg System) or central air-conditioning automati...

AI Technical Summary

Problems solved by technology

[0004]2) The building automation system is a huge system engineering, and the implementation cost and comprehensive application are relatively complicated. At the same time, the design of the building automation system is independent for a certain building Design, can not achieve common use with other buildings

[0005]3) Once the building automation system is implemented, it is difficult to move the application

[0008]2) In terms of implementation, it is also designed according to the central air conditioning system of a certain building. After the design is completed, a system is only used in the central air conditioning system of the targeted building Air-conditioning system, not universally applicable to central air-conditioning systems of other buildings

[0009]3) Portability is not considered in implementation and application, and it is difficult to move the system after completion
