FAN UNIT FOR AN HVAC SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044523 titled 'FAN UNIT FOR AN HVAC SYSTEM

Simplified Explanation

The abstract describes a patent application for a heating, ventilation, and/or air conditioning (HVAC) blower assembly. The assembly consists of a motor and a fan wheel, where the motor drives the rotation of the fan wheel. The blower housing, which accommodates the fan wheel, is defined by a base, a curved boundary, a front boundary, and a rear boundary. An inlet port allows airflow to enter the fan wheel, while an outlet port allows the airflow to be expelled. The curved boundary includes an involute profile and a footing that guides the airflow away from the fan wheel.

  • The patent application is for a blower assembly used in HVAC systems.
  • The assembly includes a motor that drives a fan wheel to generate airflow.
  • The blower housing, which houses the fan wheel, has an inlet port for airflow intake and an outlet port for airflow expulsion.
  • The curved boundary of the blower housing includes an involute profile and a footing that guides the airflow away from the fan wheel.
  • The invention aims to improve the efficiency and effectiveness of HVAC systems by optimizing the airflow direction and reducing turbulence around the fan wheel.

Potential Applications:

  • HVAC systems in residential, commercial, and industrial buildings.
  • Automotive HVAC systems.
  • Air purifiers and ventilation systems.

Problems Solved:

  • Reduces turbulence and improves airflow efficiency.
  • Prevents recirculation of expelled air.
  • Guides the airflow away from the fan wheel to prevent interference.

Benefits:

  • Increased efficiency and effectiveness of HVAC systems.
  • Improved air quality and circulation.
  • Reduced energy consumption and operating costs.
  • Enhanced comfort and temperature control in indoor environments.


Original Abstract Submitted

a heating, ventilation, and/or air conditioning (hvac) blower assembly includes a motor and a fan wheel, wherein the motor drives rotation of the fan wheel about an axis of rotation. a blower housing accommodates the fan wheel within a hollow portion and is defined by a base, a curved boundary, a front boundary, and a rear boundary. an inlet port extending through the front boundary facilitates intake of airflow into the fan wheel. an outlet port extending through the base facilitates expulsion of the airflow from the fan wheel. a first portion of the curved boundary includes an involute profile and a second portion of the curved boundary includes a footing extending from the first portion to the base such that airflow exiting through the outlet port is guided away from the fan wheel by an interior-facing surface of the footing.
