Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner systems operating in heating mode face challenges with defrosting control due to limited computing power of controllers, leading to increased operating and maintenance costs and inefficiencies in complex defrosting logic operations.
Innovation Solution
An air conditioner system that includes an outdoor unit communicatively connected to a cloud platform, which collects and analyzes operating parameters to determine defrosting decisions, sending instructions to the outdoor unit to start or end defrosting based on preset conditions, thereby offloading complex logic operations from the controller and improving computing power and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the controller in the outdoor unit performs complex defrosting logic operations, then the defrosting control accuracy is improved, but the computing power requirement and system complexity increase
Solution Approach 1:
The patent extracts the complex defrosting logic operations from the outdoor unit controller and transfers them to the cloud platform. The cloud platform receives operating parameters from the outdoor unit, performs the complex defrosting decision-making, and sends control instructions back to the outdoor unit. This reduces the computing burden on the outdoor unit controller while maintaining high defrosting control accuracy through cloud-based processing.
2Productivity
If the outdoor unit performs defrosting operations frequently, then the heat exchange efficiency is improved, but the operating and maintenance costs increase
Solution Approach 1:
The patent implements a feedback mechanism where the cloud platform continuously monitors operating parameters including heat exchange pipe temperature, exhaust pressure, exhaust temperature, and defrosting timing. Based on this feedback, the cloud platform optimizes defrosting decisions to balance heat exchange efficiency with energy consumption, determining the optimal moments for defrosting operations to avoid unnecessary cycles while preventing performance degradation.

AI summary
An air conditioner system includes an air conditioner and a cloud platform. The air conditioner includes an indoor unit and an outdoor unit. The cloud platform is configured to: in a case where the air conditioner is in a heating mode, determine that the outdoor unit performs one of defrosting and ending defrosting; if determining that operating parameters of the outdoor unit satisfy a first preset condition, send a first sub-instruction to the outdoor unit, so that the outdoor unit starts defrosting according to the first sub-instruction; if determining that the operating parameters satisfy any one of a plurality of second preset conditions, send a second sub-instruction to the outdoor unit, so that the outdoor unit ends defrosting according to the second sub-instruction.
