ACS systems manufactured by AO AMZ Ventprom automatically maintain necessary air environment conditions in a tunnel and premises and provide continuous monitoring and archiving of air environment parameters and equipment condition data.
TUNNEL VENTILATION AND EQUIPMENT
Purpose
Automation control systems manufactured by AO AMZ Ventprom automatically maintain necessary air environment conditions in a tunnel and premises and provide continuous monitoring and archiving of air environment parameters and equipment condition data.
In addition to the reliable operation of tunnel ventilation equipment, the control system performs a comprehensive algorithm of tunnel equipment operation, which includes: tunnel rooms` ventilation units, heating units, a set of emergency gates and valves, tunnel alarm, and light indicators

SUBWAY VENTILATION ARRANGEMENT
As a rule, in vehicular tunnel ventilation systems, jet ventilation units (VSA, VSB types) provide ventilation in normal mode.
In case of fire or an essential excess of harmful impurities` concentration in a tunnel, fan units' automatic control systems (AV type) are activated, starting the units at maximum capacity.
The ventilation system switches to emergency operation mode and removes harmful impurities from the tunnel.
In case of fire or an essential excess of harmful impurities` concentration in a tunnel, fan units' automatic control systems (AV type) are activated, starting the units at maximum capacity.
The ventilation system switches to emergency operation mode and removes harmful impurities from the tunnel.
Control systems operate in automatic mode and control ventilation systems and other equipment in the tunnel as the concentration of harmful substances increases or decreases. Gas pollution detectors, which transmit the readings of the current concentration of the pollutants to the ACS, are located on the upper parts of the tunnel walls.
The tunnel ventilation system comprises:
1 fan control cabinet, designed for the functioning of the logic of the whole system and parameters` control; when the frequency converter operates.
2 power cabinets, which receive control signals from the control panel and contain the power part of the system, designed for direct start-up and regulation of the tunnel and tunnel complex operation.
The number of power cabinets depends on the amount of devices in the system (fans, gates, tubular electric heaters).Ventilation scheme of subway constructions is based on the geometry and depth of the tunnel location, the characteristics of the traffic flow, and external wind pressure. Moreover, the control systems simulate scenarios of the most likely emergencies, assess the degree of risk to people, and develop an algorithm of the ventilation system in case of emergencies.

Control system functions
– control of the system readiness for start-up;
– control of opening of gates and valves of the system;
– operation of the control system in fully automatic mode;
– control of current parameters of the system operation (motor temperature, vibration level, pressure);
– soft start of fans and frequency regulation of their rotation speed;
– motor start without the frequency converter and logic controller participation in case of their failure;
– control of pressure and condition of filters on the fans` output;
– control of gas pollution in the tunnel and emergency situations in continuous mode
– programmable blockings of the control system operation;
– automatic regulation of the supply air temperature;
– programmable protections of the main drive motor;
– heating of the fan motors in standby mode;
– creating databases of events, fan operation parameters in the internal storage;
– possibility of control and monitoring of the system operation through the Ethernet network (Modbus TCP network);
– possibility of the system control from the remote and local control panel.

SYSTEM FEATURES
High reliability and functionality of the control system are achieved by:
– application of frequency converters for control oftunnel fans` rotation speed;
– continuous monitoring of the air environment in the tunnel and tunnel rooms (air temperature, gas and harmful impurities concentration);
– control of the system equipment parameters (fans vibration, bearings` temperature, motor current, air pressure/flow rate control);
– possibility of operation of the system in fully automatic mode (switching on, switching off, and algorithm of operation of the system equipment is performed by sensors that monitor the state of the air environment in the tunnel);
– in this case a supervisor can intervene in the control process at any time;
– archiving of the parameters of the air environment and state of the system equipment data (including the emergencies);
– implementation of the supervisory control of the system, monitoring, and data archiving via Modbus RTU or Modbus TCP protocols from the operator computer (APC)
