Solution Overview
Problem
Current ducted air conditioner systems face challenges in accurately determining the optimal static pressure section during installation, leading to inefficiencies and suboptimal operation due to manual methods and error-prone calculations.
Innovation Solution
A method and device that automatically divide the static pressure into sections based on a preset rule, detecting the actual working current to determine the suitable section, using a ratio of current differences to select the optimal section, allowing the air conditioner to adapt to the installation environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual method is used to determine static pressure sections and set rotating speeds, then the system can be operated, but it is uneasy to acquire specific static pressure and difficult to acquire optimum section
Solution Approach 1:
The system automatically detects the actual working current of the fan motor and uses this data to determine the optimal static pressure section without requiring manual intervention. The control unit self-adjusts by comparing detected current values with preset current ranges for different sections, enabling the system to serve itself in determining operating parameters.
Solution Approach 2:
The system implements feedback by detecting the actual working current of the fan motor and using this information to adjust the operating section. The control unit continuously monitors current consumption and compares it with preset ranges to determine which static pressure section the system is currently in, enabling automatic adaptation to actual operating conditions.
2Adaptability or versatility
If dial manner or drive-by-wire manner is used to control the ducted air conditioner, then each rotating speed corresponding to each gear can be acquired, but it requires manual setting and does not automatically adapt to installation environment
Solution Approach 1:
The system automatically detects the actual working current of the fan motor and uses this data to determine the optimal static pressure section without requiring manual intervention. The control unit self-adjusts by comparing detected current values with preset current ranges for different sections, enabling the system to serve itself in determining operating parameters.
Solution Approach 2:
The system replaces manual mechanical adjustment (dial manner or drive-by-wire) with automated electronic control based on electrical parameter detection. Instead of manually setting rotating speeds through mechanical interfaces, the system uses electrical current detection and electronic control to automatically determine and adjust operating parameters.

AI summary
The present disclosure provides a method and a device for adaptively regulating a static pressure of a ducted air conditioner, and a ducted air conditioner. The method includes: dividing the static pressure in an air duct into a preset number of sections; selecting the sections i and i + 1, and detecting respectively the gears corresponding to the sections i and i + 1, the rotating speeds Ri and Ri+1, and an actual working currents Ii and Ii+1; and judging whether Ii and Ii+1 are within the normal current ranges respectively; and selecting the final section according to the judging result. With the method, the air duct conditioner may automatically select and determine a section according to actual installation environments, and may automatically determine an optimum section in which the ducted air conditioner works.
