Comprehensive energy-saving control system for ventilation air conditioner of subway station

Abstract

The invention discloses a comprehensive energy-saving control system for a ventilation air conditioner of a subway station. The comprehensive energy-saving control system comprises a field monitoring execution layer, an acquisition control layer and a monitoring management layer. The comprehensive energy-saving control system is suitable for the technical field of energy-saving control of the ventilation air conditioner of the subway station, variable air volume control and a variable frequency speed regulation technology are combined for control, energy can be reasonably utilized, the operation condition of the subway station can be improved, a wind system and a water system are monitored in a unified mode under the normal working condition, the system efficiency is optimized under the condition that the whole system meets the tail end load requirement, and wind and water coordination linkage control of the whole system is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy-saving control of ventilation and air conditioning of subway stations, in particular to a comprehensive energy-saving control system of ventilation and air conditioning of subway stations. Background technique [0002] The subway is an underground transportation tool with a large capacity and high energy consumption. The power consumption of the ventilation and air-conditioning system of the subway station accounts for about 60% of the electricity consumption of the subway station. The subway lines opened before 2016 were only considered in the preliminary design and planning. Control technology does not deploy a dedicated energy-saving control system, so energy-saving regulation of the entire ventilation and air-conditioning system cannot be achieved, and energy waste is quite serious. [0003] However, the selection of general ventilation and air-conditioning equipment is determined according to ...

AI Technical Summary

Problems solved by technology

In the absence of a dedicated energy-saving control system, station ventilation and air-conditioning equipment basically operates at a constant speed, no matter how the station’s air-conditioning load changes, so energy waste is quite serious

[0004] Moreover, in the existing ventilation and air-conditioning systems of subway stations, the air system and the water system are monitored separately, and the real-time changes in the system load cannot be regulated and controlled through the organic connection between the wind and water systems.
