PHOTOCATALYTIC OXIDATION CENTRIFUGAL FAN - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033396 titled 'PHOTOCATALYTIC OXIDATION CENTRIFUGAL FAN

Simplified Explanation

The abstract describes a centrifugal fan for HVACR systems. The fan includes a volute housing with an inner surface and a curved inlet shroud, defining an air outlet and an air inlet respectively. The fan also has an impeller with fan blades and a light source. Both the inner surface of the volute housing and the outer surface of the fan blades have a photocatalyst layer. The light source emits light on the photocatalyst layer.

  • The centrifugal fan is designed for heating, ventilation, air conditioning, and refrigeration systems.
  • It includes a volute housing with an inner surface and a curved inlet shroud.
  • The volute housing defines an air outlet, while the curved inlet shroud defines an air inlet.
  • The air inlet has a cross-sectional area that is perpendicular to the outlet airflow cross-sectional area.
  • The fan also includes an impeller with multiple fan blades.
  • The fan blades have an outer surface.
  • The centrifugal fan further includes a light source.
  • Both the inner surface of the volute housing and the outer surface of the fan blades have a photocatalyst layer.
  • The light source emits light on the photocatalyst layer.

Potential Applications

  • Heating, ventilation, air conditioning, and refrigeration systems
  • Industrial ventilation systems
  • Commercial buildings
  • Residential buildings

Problems Solved

  • Improved air quality by incorporating a photocatalyst layer on the inner surface of the volute housing and the outer surface of the fan blades.
  • Enhancing the efficiency of HVACR systems by providing a centrifugal fan with optimized airflow design.

Benefits

  • Improved air purification by utilizing the photocatalyst layer to eliminate pollutants and odors.
  • Increased energy efficiency due to the optimized airflow design.
  • Enhanced performance and longevity of HVACR systems.
  • Potential cost savings through improved energy efficiency.


Original Abstract Submitted
