The project for automation of engineering systems of the compressor station power unit provides for:
1. Automation of the supply ventilation system P1, based on the M620.79.1 controller manufactured by the Moscow Plant of Thermal Automatics.
2. Automation of the exhaust ventilation B1.
3. Installation of control posts at the fire hydrants in the power unit to turn on the fire pumps.
Ventilation control is provided by the M620.79.1 controller, for control of the supply ventilation Shi, a logical control circuit for the exhaust ventilation B1 is assembled.
The M620.79.1 controller automatically performs standard functions for regulating the temperature of the air supplied by the supply ventilation to the serviced rooms, and also provides:
- protection of the air heater from freezing;
- switching on the backup fan when the pressure in the discharge pipe of the supply system drops below 50 Pa.
- automatic (from the controller) and remote (with buttons from the ventilation control panel).
- control of the actuator (25h940nzh) of the return coolant valve with a preliminary 3-minute warm-up at start-up.
