Solution Overview
Problem
Existing multi-split air conditioner systems can only detect overall energy consumption, failing to separately detect cooling and heating capacities, which limits the ability to assess the operational capacity of heat recovery multi-split air conditioners effectively.
Innovation Solution
A method that acquires hydraulic device data to determine the absorption outdoor unit heat quantity, and combines this with outdoor and indoor unit data to calculate condenser heating and evaporator cooling capacities, allowing for the determination of heating and cooling indoor unit capacities, and subsequently the operational capacity of the heat recovery multi-split air conditioner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only overall energy consumption is detected, then the detection system is simple, but the measurement precision of cooling and heating capacities is insufficient
Solution Approach 1:
The patent segments the overall energy consumption detection into separate cooling capacity detection and heating capacity detection components. By dividing the detection system into distinct modules for cooling and heating, the patent enables precise measurement of each capacity independently while maintaining a structured detection architecture that avoids excessive complexity.
Solution Approach 2:
The patent introduces hydraulic device data as an intermediary element to bridge the gap between overall energy consumption and specific cooling/heating capacity measurements. This intermediary data enables the calculation of absorption outdoor unit heat quantity, which serves as a key parameter for determining both cooling and heating capacities without requiring separate complex detection systems.
2Reliability
If separate cooling and heating capacity detection is implemented, then the operational capacity assessment is accurate, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional detection system that uses the same hydraulic device data and calculation methodology to determine both cooling capacity and heating capacity. This universal approach allows the system to assess operational reliability for both cooling and heating modes without requiring separate dedicated detection systems, thereby maintaining reliability while controlling complexity.
Solution Approach 2:
The patent changes the detection parameter from overall energy consumption to hydraulic device data, which enables the calculation of both cooling and heating capacities through parameter transformations. By using absorption outdoor unit heat quantity as a key parameter, the system can derive both cooling and heating capacities from the same data set, improving reliability without proportionally increasing complexity.
3Measurement precision
If hydraulic device data is used for capacity detection, then the measurement precision improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent performs preliminary action by pre-establishing the calculation relationships between hydraulic device data and capacity parameters. The system pre-defines how absorption outdoor unit heat quantity is calculated from hydraulic device data, and how this intermediate result is used to determine both cooling and heating capacities. This preliminary structuring reduces the difficulty of real-time detection and measurement.
Solution Approach 2:
The patent replaces direct mechanical or physical measurement systems with a calculation-based approach using hydraulic device data. Instead of requiring separate physical sensors and measurement devices for cooling and heating capacities, the system substitutes these with computational methods that derive capacities from hydraulic parameters, thereby improving measurement precision while reducing the complexity of physical detection infrastructure.
