Ceiling Air Conditioner Vane Module Pairing for Dead-Zone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling type indoor units of air conditioners have difficulty in effectively controlling discharge vane modules to rapidly cool rooms, leading to inefficient cooling distribution and unsatisfied user preferences.
Innovation Solution
The method involves configuring four vane modules into two pairs that discharge air at different angles or directions, alternately providing indirect and direct wind, to enhance cooling efficiency and coverage.

If the discharge vane is simply controlled (rotated repeatedly or kept stationary), then the device complexity is low, but the cooling efficiency and user satisfaction are insufficient
Solution Approach 1:
The discharge vane is divided into four independent vane modules (first, second, third, and fourth modules) arranged at different positions around the discharge port. Each module can be independently controlled to discharge air in different directions, enabling more sophisticated cooling patterns without requiring a single complex control mechanism.
Solution Approach 2:
The control method dynamically adjusts the operation of different vane modules based on cooling requirements. During rapid cooling mode, all four modules operate simultaneously with specific modules activated in sequence. During normal cooling mode, only two opposite modules operate. This dynamic control optimizes cooling efficiency while managing system complexity.

If opposite two vane modules discharge air simultaneously, then the cooling coverage is improved, but the air flow distribution becomes less flexible
Solution Approach 1:
The control method employs periodic activation of different vane modules. During rapid cooling mode, modules are activated in a specific sequence (first and third modules simultaneously, then second and fourth modules simultaneously) with timing control. This periodic operation creates alternating air flows that enhance cooling coverage while maintaining flexibility through temporal separation of module operations.

AI summary
Opposite two of four vane modules constitute a first discharge pair, the other two constitute a second discharge pair, and the first discharge pair and the second discharge pair alternately provide indirect wind and direct wind, whereby it is possible to rapidly cool a room. In addition, the first discharge pair and the second discharge pair discharge air at different angles, whereby it is possible to minimize a dead zone that discharged air does not reach.
