CENTRIFUGAL AIR-SENDING DEVICE AND AIR-CONDITIONING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240026896 titled 'CENTRIFUGAL AIR-SENDING DEVICE AND AIR-CONDITIONING APPARATUS
Simplified Explanation
The abstract describes a centrifugal air-sending device with blades that have different lengths and proportions in different regions. The blades closer to the outer circumference have a higher proportion of a sirocco vane portion compared to a turbo vane portion.
- The centrifugal air-sending device has blades with varying lengths and proportions in different regions.
- Blades closer to the outer circumference have a higher proportion of a sirocco vane portion.
- The device includes a bell mouth with an inner circumferential side end portion.
- The blade outer circumferential portion is formed to have a higher proportion of the sirocco vane portion than or equal to the turbo vane portion.
Potential Applications:
- HVAC systems
- Industrial ventilation systems
- Cooling systems for electronic devices
- Automotive air conditioning systems
Problems Solved:
- Improved airflow efficiency
- Enhanced cooling performance
- Reduced noise and vibration
Benefits:
- Increased energy efficiency
- Improved cooling capacity
- Quieter operation
- Enhanced overall performance
Original Abstract Submitted
a centrifugal air-sending device has blades that each have a vane length in a first region that is greater than a vane length in a second region and have a portion at which a proportion for which a turbo vane portion accounts is higher in a radial direction than a proportion for which a sirocco vane portion accounts in the first region and the second region. the blades that are located closer to an outer circumference than is an inner circumferential side end portion of a bell mouth that is located closest to an inner circumference in the radial direction is defined as a blade outer circumferential portion that is formed such that the proportion for which the sirocco vane portion accounts is higher in the radial direction than or equal to the proportion for which the turbo vane portion accounts in the first region and the second region.
