Industrial factory building safety energy-saving mixed ventilating control system

An industrial plant safety and fuel mixing ventilation control system, belonging ventilation engineering and control technology fields, including control devices, mechanical ventilators, inverter, three temperature sensors, voltage and current sensors. By monitoring the temperature of natural ventilation, the total input power outdoor temperature and industrial plants, according to the principle of conservation of energy, natural ventilation calculation principle and safety of industrial plants indoor set temperature is calculated in real-time to determine the mechanical ventilation of industrial plants need, and curing in the control device, according to the frequency converter fan - air flow characteristics of the fan input frequency reasonable control, in order to achieve industrial plant hybrid power-saving control of the ventilation system. The present invention is easy installation and maintenance, not only to ensure the safe operation of industrial plants and energy-saving effect is very obvious, with good economic and social benefits.
