Energy saving and automation control design of HVAC system in BSCE new factory

As the original air conditioning system of BSCE new factory has limit automation control device, it is mainly controlled manually and the cooling/heating output of the air conditioning system cannot be regulated, which causes uncomfortable indoor environment and energy waste. By analysing the energy consumption of the HVAC system, puts forward the automation control and energy saving reformation scheme and puts it into effect. After the reformation, the energy consumption is continually monitored and evaluated. The result shows that the total energy saving is 513.5 MWh of electricity power and 14 100 m³ of natural gas, the energy consumption per 10 000 Yuan production decreases 14.6% and the CO₂ emission reduces 539 tons per year.
