Solution Overview
Problem
Existing refrigeration systems for multiple containers lack synchronous operation, leading to inefficiencies in refrigeration and cooling processes due to separate control of each container without consideration for coordinated operations.
Innovation Solution
A refrigeration system with communication units that enable synchronized control of refrigeration apparatuses across multiple containers, ensuring coordinated refrigerating-cooling and defrosting operations through a main control unit and slave units, with measures for handling faulty components and temperature detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If refrigeration apparatuses of multiple containers are separately controlled, then each container can independently perform refrigerating-cooling operation, but synchronous operation between containers is not achieved leading to inefficiency
Solution Approach 1:
The patent merges the control functions of multiple refrigeration apparatuses into a unified system where a main control unit coordinates with slave control units. This allows synchronous operation of multiple containers while maintaining individual control capabilities, resolving the contradiction between independent operation and coordinated efficiency.
Solution Approach 2:
The control units exchange operational information through communication units, creating a feedback mechanism that enables synchronous control. The main control unit receives status information from slave units and coordinates operations to achieve efficient synchronous refrigeration and defrosting across multiple containers.
2Loss of energy
If refrigeration apparatuses operate without synchronous control, then device simplicity is maintained, but energy waste occurs due to uncoordinated refrigerating-cooling and defrosting operations
Solution Approach 1:
The synchronous control system ensures continuous and coordinated refrigeration operation across all containers. By coordinating the start and end times of refrigerating-cooling and defrosting operations, the system eliminates idle time and energy waste while maintaining continuous useful refrigeration action.
Solution Approach 2:
Communication units serve as intermediaries between control units, enabling energy-efficient coordination without requiring complex direct control connections. This intermediary mechanism allows simple yet effective energy optimization through synchronous operation scheduling.
3Volume of stationary object
If multiple containers are joined to form storage, then storage capacity is increased, but temperature consistency across containers becomes difficult to maintain with separate control
Solution Approach 1:
The control system provides universal temperature control functionality across all joined containers. The main and slave control units work together to maintain consistent temperature standards throughout the entire storage space, regardless of the number or configuration of individual containers, enabling multi-functionality while ensuring temperature uniformity.
