Abstract—University libraries are usually high energy-consuming buildings on campus and the
operation efficiency of the air conditioning system is still far from satisfactory.
Combined with the building automation technology, heating, ventilation and air-conditioning (HVAC)
control systems for university library buildings have been proposed via fieldbus
communication. The analysis of control systems from the electrical technology field is
presented because traditional automatic control design cannot reflect the relationship between
air-conditioning automatic control systems and electronic devices in detail. Furthermore, since a frozen station is one
of the largest energy components in an air conditioning system, the optimization of the cooling
water system in a frozen station is carried out as an example to explain
its electrical principle. The control program of the cooling water system is
compiled through Delta WPL software and frequency converter. Building energy management
control systems has been proven to reduce energy consumption on campus via the
simulation of eQUEST software.
