Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for estimating air conditioner power consumption rely on laboratory data, which results in significant errors due to factors like geographical location, outdoor environment, indoor conditions, and machine type, leading to inaccurate energy-saving evaluations.
Innovation Solution
A method and device that acquire operating parameters from multiple air conditioners in the same region and time period to calculate power correction coefficients, allowing for a more accurate estimation of power consumption by averaging correction powers and applying these coefficients to estimate the power consumption of a target air conditioner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power consumption is estimated using laboratory data, then the estimation method is simple, but the measurement precision is poor due to large errors from geographical location, outdoor environment, indoor environment, house type and machine type factors
Solution Approach 1:
The patent creates a virtual copy of the target air conditioner by selecting reference air conditioners with matching types from the same region and time period. This copying approach allows the estimation to reflect actual operating conditions rather than idealized laboratory data, thereby improving measurement precision while maintaining reasonable method complexity through automated data matching and correction coefficient calculation
Solution Approach 2:
The patent introduces region-specific and time-specific correction coefficients (αi) that dynamically adjust the estimation based on local environmental factors and operational conditions. By changing the parameters from fixed laboratory values to dynamic correction factors derived from actual operating data, the system achieves higher measurement precision without excessive complexity
2Measurement precision
If power consumption is estimated using reference air conditioners from the same region and time period with correction coefficients, then the measurement precision is improved, but the device complexity increases due to data acquisition and calculation requirements
Solution Approach 1:
The patent creates a universal estimation framework that can handle multiple air conditioner types, regions, and time periods through a single standardized process. The correction coefficient calculation method works across different reference air conditioners and target units, reducing the need for separate complex systems for each scenario while maintaining high measurement precision through consistent application of the estimation formula
Solution Approach 2:
The system automatically selects appropriate reference air conditioners and calculates correction coefficients without requiring manual intervention. The data acquisition and processing occur self-service through automated querying of operating parameters and computational determination of αi values, which reduces operational complexity even though the underlying data processing capabilities are enhanced
