The Practice of Efficient Operation and Maintenance Management of Refrigeration Room in Railway Passenger Stations
This article explores how to improve the operational EER of chiller plants in railway passenger stations from the perspective of operation and maintenance management through the practice of Beijing Chaoyang Station.It is suggested that comprehensive adjustment and control strategy optimization should be carried out for the newly built plants from completion acceptance to stable cooling,and the direction of adjustment and optimization is provided;It is also suggested to establish an effective energy efficiency monitoring and management system,including regular analysis and benchmarking of cooling capacity and energy efficiency indicators,and optimizing management systems in a timely manner based on energy efficiency indicators;A system for regular maintenance of sensors and energy efficiency monitoring instruments has been proposed,and a scientific equipment maintenance concept based on alarm closed-loop management and"preventive maintenance"based on operating data has been proposed to ensure and achieve the goal of high-efficiency operation in a chiller plant.This article can provide reference and guidance for the operation and maintenance management of chiller plants in railway passenger stations.
