Smart Air-filters for Air-handling Unit (AHU)

Title of I&T Wish Smart Air-filters for Air-handling Unit (AHU)
(REF : W-0183)
Project Summary and Challenges Traditional filtration inside air handling unit (AHU) mainly depends on the main filter inside air handling unit (AHU), this reduce the service lifetime of main filter.
  • The objective of the project is to extend the services lifetime of main filter in air handling unit (AHU) by increasing the capability of the prefilter.
  • To further enhance the energy-efficiency of the main filter, control logic or a novel mechanism is required to be devised for the operation of main filter.
  • To optimize the operation and evaluate the effectiveness of the deliverables, a real-time monitoring, control and data-logging system is required to be developed. Operation status and data shall be accessible in the website.
Expected Outcome
  1. To enhance the filtration efficiency of AHU pre-filter without increasing its pressure drop in an energy-efficient way.
  2. To enhance the filtration efficiency of AHU main filter without increasing its pressure drop in an energy-efficient way.
  3. To develop a control logic or mechanism for the optimization of main filter's energy-efficiency and operation status.
  4. To develop real-time monitoring, control and data-logging system for the illustration and evaluation of the effectiveness of the technology.
  5. To prepare the submission material for patent application.
Expected Project Duration 12 months
