Solution Overview
Problem
Multi-type air conditioning systems often include non-optimized control parameters, leading to decreased heating and cooling capacity and increased power consumption, as they are standardized across various installation scenarios.
Innovation Solution
The system employs sensors and short-distance wireless devices to detect and transmit operational data, allowing for real-time optimization of control parameters based on individual unit conditions, including positional relationships and abnormality detection, thereby adjusting settings such as target superheat degrees and fan speeds to enhance performance and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard set values of control parameters are used to enhance versatility, then the system can be installed in various situations, but the heating and cooling capacity decreases and power consumption increases
Solution Approach 1:
The control parameters are changed dynamically based on detected sensor information about refrigerant state and device conditions. The air conditioning control device adjusts control parameters in real-time according to the actual installation situation, transforming from static standard values to dynamic optimized values that adapt to specific conditions.
Solution Approach 2:
The invention changes the control parameters of the air conditioning control based on detected sensor information. By modifying parameters such as target superheat degree and other control settings according to actual installation conditions, the system optimizes heating and cooling capacity while reducing power consumption.
2Productivity
If sensor information is transmitted directly to the control device, then real-time optimization is achieved, but data communication volume increases
Solution Approach 1:
The abnormality detection unit extracts only the essential abnormality signals from the sensor information, separating critical data from raw sensor data. This allows the system to transmit only the necessary abnormality signals to the air conditioning control device, reducing communication volume while maintaining optimization effectiveness.
Solution Approach 2:
The abnormality detection unit acts as an intermediary between the sensors and the air conditioning control device. It processes sensor information and generates abnormality signals that convey essential information about device state, reducing the amount of data that needs to be transmitted while preserving the ability to optimize control parameters.
