Multi-Container Refrigeration System with Synchronized Defrost Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration systems for multiple containers lack synchronous operation capabilities, leading to inefficiencies and potential overcooling or incomplete defrosting across the storage configuration.
Innovation Solution
A refrigeration system that utilizes communication units to synchronize the operation of refrigeration apparatuses across multiple containers, ensuring coordinated start and end times for defrosting and refrigerating-cooling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If refrigeration apparatuses in multiple containers are separately controlled, then each container can independently perform refrigerating-cooling operations, but synchronous operation between containers is not achieved leading to operational inefficiency
Solution Approach 1:
The patent merges the control functions of multiple refrigeration apparatuses into a unified control system. The control unit receives temperature information from all containers and issues synchronized control signals to coordinate defrosting and refrigerating-cooling operations across all containers simultaneously, transforming independent control into integrated control for improved operational efficiency.
2Reliability
If refrigeration apparatuses operate independently without synchronization, then control system is simpler, but overcooling or incomplete defrosting may occur across the storage configuration
Solution Approach 1:
The patent implements a feedback mechanism where temperature information from each container is continuously monitored and fed back to the control unit. Based on this feedback, the control unit dynamically adjusts and coordinates the operation timing of defrosting and refrigerating-cooling across all containers, ensuring consistent temperature management and preventing overcooling or incomplete defrosting.
3Reliability
If synchronous operation is implemented across multiple containers, then temperature management consistency is improved, but communication infrastructure and control coordination are required
Solution Approach 1:
The patent employs a universal control unit that can manage multiple refrigeration apparatuses across different containers through a standardized communication interface. This multi-functional control system handles temperature monitoring, defrosting coordination, and refrigerating-cooling synchronization across all containers using a unified control strategy, reducing the need for separate control systems in each container.
