Analysis on automatic control strategy of variable air volume air conditioning system in standard office units of Asia Finance Building

This paper focuses on the analysis of the operation strategy of the curtain wall side fan-coil unit combined with the variable air volume(VAV) air conditioning system in the main air duct variable static pressure adjustment process to effectively realize the overall control. The control of curtain wall side fan-coil unit is incorporated into the VAV air conditioning automatic control system for overall control, which avoids the temperature imbalance easily caused by the independent control of two systems in the same area in the past projects. At the same time, the static pressure setting value constant step adjustment method is adopted to realize the variable static pressure regulation of main air duct through simple and effective control logic. After a winter and summer operation test, the results show that the air conditioning automatic control system meets the requirements of variable static pressure adjustment, and realizes the overall control of the curtain wall side fan-coil unit and the VAV air conditioning system.
