SYSTEM OF AUTOMATION OF MAIN FAN INSTALLATION Russian patent published in 2016 - IPC E21F1/00 

FIELD: heating.

SUBSTANCE: invention relates to the mining industry, in particular to the systems of automation of fan installations, and can be used to ensure safe, energy- and resource-saving ventilation of underground mining enterprises. The system of automation of the main fan installation (MFI) comprises a microcontroller unit (MCU) connected to the sensors monitoring air parameters involved in the process of ventilation, a setting device of MCU electric drive, and also air flow sensors mounted in the shaft insets of the air supply mine shafts. The air supply shaft located farther away from the ventilation shaft is equipped with a surface air conditioning device (ACD). The air supply shaft closer to the ventilation shaft is equipped with an underground ACD. Both ACDs are connected to the device of setting their cooling capacity. The evaporator of the underground ACD is located in the shaft inset of the air supply shaft closer to the ventilation shaft, and the condenser - in one of the main ventilation openings passing to the ventilation shaft. The MCU is made with the ability to supply control commands to the device of setting cooling capacity of the surface and underground ACD depending on the parameters of the external air.

EFFECT: enhanced functional capabilities by high-performance operation of the system in a warm season, taking into account the parameters of external air.
