Solution Overview
Problem
Existing power consumption detection systems for multi-split air conditioners only detect overall power consumption, failing to individually measure the power consumption of each indoor unit and hydraulic device, leading to inefficiencies and lack of detailed energy usage insights.
Innovation Solution
A method that acquires hydraulic device data to determine heat absorption values, combined with outdoor and indoor unit data, to calculate condenser heating and evaporator cooling capacities, allowing for the precise determination of indoor unit and hydraulic device power consumption based on these values and current operation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only overall power consumption is detected, then the detection system is simple, but detailed energy usage information is lost
Solution Approach 1:
The patent segments the overall power consumption into distinct components by detecting power consumption of individual indoor units and the hydraulic device separately. This is achieved through separate detection circuits for each component, allowing detailed energy usage information to be obtained without requiring a completely complex new system architecture.
Solution Approach 2:
The patent introduces a controller as an intermediary that coordinates the separate detection of indoor unit power consumption and hydraulic device power consumption. The controller aggregates these individual measurements to provide comprehensive energy usage information, acting as a mediator between the separate detection components and the overall system monitoring.
2Measurement precision
If separate detection of indoor units and hydraulic device is implemented, then detailed power consumption information is obtained, but the detection system becomes more complex
Solution Approach 1:
The detection system is segmented into multiple independent detection circuits, each dedicated to measuring power consumption of specific components (indoor units and hydraulic device). This segmentation enables precise measurement of each component's power consumption while keeping each detection circuit relatively simple and modular.
Solution Approach 2:
The patent employs a universal detection approach where similar detection circuits are used across different components (indoor units and hydraulic device). This multi-functionality allows the system to achieve high measurement precision for multiple components using standardized detection methods, reducing overall system complexity through reuse of proven detection architectures.
