[0002] Subway ventilation and air conditioning systems usually adopt fixed or simple feedback control modes, which makes it difficult to respond to complex dynamic environments and changes in personnel distribution in real time.

At the same time, traditional systems lack comprehensive consideration of the external environment and internal real-time air quality, and fail to effectively achieve intelligent energy-saving control. In recent years, some environmental control technologies based on real-time sensor data have gradually emerged, but most of them take a single system (wind or water) as the control target, do not fully integrate the linkage optimization of the wind system and the water system, and have a coarse granularity in regional control, which makes it difficult to meet the needs of subway operations for a balance between energy saving and comfort.

The control of the two-way valve introduces an insensitive link to avoid frequent operation of the two-way valve.

[0064] In this embodiment, the air conditioning water control strategy includes: sequential control and linkage regulation of the air conditioning water system. When the air conditioning water system is started and stopped, it needs to be controlled in sequence, for example: the order of opening the water system equipment is to open the electric butterfly valve of the cooling water and chilled water circuits → after receiving the butterfly valve opening signal, start the cooling tower at the lowest frequency → start the freezing pump → after receiving the freezing pump operation signal, give the chiller start signal → according to the comprehensive energy efficiency optimal linkage regulation of the cooling water pump, cooling tower and chiller itself; the order of closing the water system equipment is to output the chiller shutdown signal → the chiller executes the shutdown, and automatically stops the operation of the cooling water pump and cooling tower → close the electric butterfly valve of the cooling water circuit → after receiving the chiller shutdown signal for 60s, turn off the chilled water pump → close the electric butterfly valve of the chilled water circuit.

[0065] In this embodiment, the air conditioning water control strategy also includes: the energy-saving control system controls the chiller unit by adjusting the number of operating chillers according to the load conditions, which is mainly divided into load host operation quantity control and unload host operation quantity control.

[0066] In this embodiment, the air conditioning water control strategy also includes: chilled water system control, where the chilled water is a primary variable frequency pump system. When multiple pumps are running, each pump must run at the same frequency. In order to avoid the waste of water pump energy caused by large flow and small temperature difference operation, the chilled water pump is frequency-controlled according to the chilled water supply and return water temperature difference (the design temperature difference is 5°C). When the actual temperature difference is greater than the design temperature difference, the frequency is increased; when the actual temperature difference is less than the design temperature difference, the frequency is reduced.

[0067] In this embodiment, the air conditioning wind control strategy includes: real-time frequency control of the small fresh air air conditioning mode. The small fresh air air conditioning mode is an operating condition used under high temperature and high humidity conditions outdoors in summer. Its main feature is to reduce the entry of outdoor fresh air and avoid excessive fresh air load.

[0068] In this embodiment, the air conditioning wind control strategy also includes: real-time frequency control of the fresh air air conditioning mode. The fresh air air conditioning mode is an operating condition used when the outdoor temperature is low during the air-conditioning season. Its main feature is to make full use of the outdoor low-temperature fresh air and reduce the air conditioning load. The air delivered by the fresh air condition is all fresh air, so the fresh air volume can be guaranteed and there is no need to worry about insufficient fresh air.

[0069] In this embodiment, the air conditioning wind control strategy also includes: real-time control of the frequency of the ventilation mode, The ventilation mode is an operating condition used when the outdoor temperature is low during the non-air-conditioning season. Its main feature is to fully utilize the low-temperature outdoor fresh air to cool the station. The air delivered by the ventilation mode is all fresh air, so the fresh air volume can be guaranteed.

[0070] The beneficial effects of the above technical solution are as follows: determining the control strategy based on the target temperature and target humidity of the stepped area, and conducting Feng Shui linkage energy-saving control of the subway based on the control strategy, which can optimize the equipment coordination efficiency and improve the accuracy and energy-saving effect of subway regulation.
