Solution Overview
Problem
Existing power consumption detection systems for heat recovery multi-split air conditioners can only detect overall consumption, failing to provide detailed power consumption data for individual indoor units, which limits energy management and efficiency.
Innovation Solution
A method and apparatus that acquire multi-split air conditioner operation modes and information to determine specific indoor unit power consumption by filtering units, extracting relevant parameters like electronic expansion valve flow coefficients and outdoor unit operation data, enabling precise calculation of total power consumption for each indoor unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If overall power consumption detection is used for the heat recovery multi-split air conditioner, then the detection system is simple and easy to implement, but the detailed power consumption data for individual indoor units cannot be obtained
Solution Approach 1:
The patent segments the overall power consumption detection into individual indoor unit power consumption detections. By dividing the multi-split air conditioner system into separate detectable units, the system can now measure power consumption for each indoor unit independently while maintaining a manageable detection architecture through modular sensor placement and distributed measurement approaches.
2Loss of information
If individual indoor unit power consumption detection is implemented, then detailed energy management data is obtained, but the detection system becomes more complex
Solution Approach 1:
The patent implements a universal detection framework where the power consumption detection system serves multiple functions: it detects overall system power consumption, individual indoor unit power consumption, and provides data for energy management optimization. This multi-functional approach eliminates the need for separate detection systems for different measurement needs, thereby reducing overall system complexity while achieving comprehensive energy management information.

AI summary
An indoor unit power consumption detection method includes: acquiring a multi-split air conditioner operation mode and multi-split air conditioner information of a heat recovery multi-split air conditioner and determining to-be-detected indoor units based on the multi-split air conditioner information. The method includes acquiring indoor unit operation modes of the to-be-detected indoor units and obtaining a target indoor unit by filtering, based on the multi-split air conditioner operation mode and the indoor unit operation modes, the to-be-detected indoor units; acquiring indoor unit information of the target indoor unit and outdoor unit information of the heat recovery multi-split air conditioner; and determining total power consumption of the target indoor unit based on the indoor unit information and the outdoor unit information.
