AI Technical Summary

Technical Problem

Existing air conditioner fresh air modules only have a single fresh air function and cannot simultaneously exhaust indoor polluted air, resulting in poor indoor air circulation and air pressure imbalance, making it difficult to maintain stable and healthy air quality.

Method used

Design an air conditioning fresh air module, which adopts a coaxial arrangement of fresh air fan and exhaust fan and is driven by the same drive motor to achieve synchronous operation of fresh air introduction and stale air exhaust. The fresh air volute and exhaust volute are arranged side by side and are connected by a connecting shaft and clearance hole structure to ensure synchronous rotation in the same direction. The non-circular hole and preset gap are combined to improve transmission efficiency and reduce noise.

Benefits of technology

It achieves efficient indoor air replacement, rapidly improves air quality, reduces production costs and energy consumption, enhances the structural compactness and operational stability of the air conditioner, and reduces noise interference.
