Subway high-efficiency machine room energy-saving control system and control method

Abstract

The invention relates to a subway high-efficiency machine room energy-saving control system and a control method. The system comprises a controller, and an air-conditioning water system water chilling unit communication module, an air-conditioning water system temperature acquisition module, an air-conditioning water system pressure acquisition module, an air-conditioning water system flow acquisition module, an outdoor weather acquisition module, an electric butterfly valve control module, an electric regulating valve control module, an air-conditioning water pump and a cooling tower variable frequency driving module and an intelligent electric meter acquisition module which are connected with the controller. Aiming at the control over each single device in a subway, an active optimization strategy is designed for controlling each single device by adopting overall analysis and taking improvement of the overall operation energy efficiency of the air conditioning system as a starting point, so that the problem that the control effects among the devices shift is fully avoided, and the energy-saving effect of each device is fully exerted; and the overall operation energy efficiency of the subway air-conditioning system is effectively improved under the condition that the subway air-conditioning environment indexes are reached.

Description

technical field [0001] The invention relates to an energy-saving control system and a control method for a subway high-efficiency computer room, belonging to the technical field of subway ventilation and air conditioning. Background technique [0002] According to relevant statistics, the operating energy consumption of ventilation and air-conditioning systems in urban rail transit underground stations reaches about 40% to 50% of the total energy consumption of the station, or even a higher proportion. With the continuous improvement of technology level and product manufacturing level, more and more energy-saving technologies (products with high energy efficiency level, energy-saving design control technology, etc.) It was found that the problem of high energy consumption still existed. [0003] The traditional solution incorporates all subway station ventilation and air conditioning system equipment, sensors, etc. into the BAS system monitoring, and the BAS system supplier...

AI Technical Summary

Problems solved by technology

The traditional control scheme does not focus on solving the above problems, but adopts simple independent control for each equipment and combines them into a system, which is limited to the optimization of the control of single equipment, independent control of air system and water system, cold water pump , cooling water pump, and cooling tower fan control strategy only focus on the energy saving of the equipment itself, ignoring the negative impact on the energy efficiency of the chiller, and lack of optimal control of the overall energy efficiency of the system
