Control system development for supply air pressure in air handling unit

Air handling unit (AHU) is one of the critical component in air conditioning and mechanical ventilation (ACMV) system. Huge belt-driven fan was used in AHU to facilitate air circulation and the fan itself used up most of the energy in AHU. Static air pressure generated by the fan can determine the e...
