CRC (Continuous Retro-Commissioning).It is the technology of Beijing Jiujian Technology Co., Ltd. with independent intellectual property rights, and has the qualification of independent research and development, production equipment and systems. In the face of the "dual carbon index" and "continuous service is needed to ensure the optimization of energy saving", in view of the various problems existing in the control of traditional systems, the RC technology is continuously optimized, resulting in CRC technology.
This technology is manifested in a set of systematic theories and methods, which improve the working performance and comprehensive performance of air conditioning, heating, lighting, ventilation, hot and cold water piping systems, as well as centralized cooling, heating and power stations in buildings by optimizing energy equipment and control systems.
The CRC metro energy-saving system is designed with the concept of "distributed control", and the energy-saving workstation is the main station of the energy-saving system, which communicates with the water system group control cabinet, the CRC energy-saving control cabinet of the fan, the chiller control box and the environmental parameter collection box to achieve comprehensive system management. Each control cabinet independently manages the controlled equipment, displays the information of each equipment respectively, and the main parameters such as fans, pumps, chillers, and valves are managed by the energy-saving system.
At present, this technology has been stably applied to the energy-saving projects of BJMTR Line 4 and Zhengzhou Metro Line 1, and has been running well so far.
