Embodiment 1
[0099] Such as figure 1 As shown, an ISCS-based ventilation and air-conditioning energy-saving control system for subway stations includes: urban rail transit integrated monitoring system (ISCS system), PLC controller, air-conditioning wind system and cold water system, database and energy-saving system workstations. The ISCS system passes PLC The controller collects data from the air-conditioning system and the cooling water system or issues control commands to the air-conditioning system and the cooling water system;
[0100] A cross-section data is periodically stored in the database: ambient temperature and humidity values, equipment operating status, frequency calculated by energy-saving strategy, opening degree, outlet water temperature setting value, enthalpy value, cooling load, mode, equipment energy consumption, etc.
[0101] The energy-saving system workstation uses the WEB framework to display energy-saving data, and stores the energy consumption of air-conditionin...
Embodiment 2
[0103] An ISCS-based energy-saving control method for ventilation and air-conditioning in subway stations, mainly for the energy-saving control of wind-water joint adjustment of air-conditioning air systems and cold water systems in subway stations during the air-conditioning season, including the following steps:
[0104] Step 1. Calculate the outdoor fresh air enthalpy value and the air enthalpy difference between the indoor station hall and the platform based on the outdoor fresh air temperature and humidity, indoor station hall and platform air temperature and humidity environment data collected in real time. According to the outdoor fresh air enthalpy value, indoor station hall and platform The air enthalpy difference is obtained from the control mode of the ventilation and air conditioning system in the public area of the station, and the control is issued to the air conditioning system through the PLC controller;
[0105] Use the configurator configuration tool of the ...
