Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defrosting control systems for refrigeration equipment face challenges in reducing power consumption while maintaining product quality and preventing frost formation, especially in response to temporary power saving requests.
Innovation Solution
A defrosting control system that includes an obtainer to determine if a power saving request is scheduled, a setting unit to create a defrosting schedule with specific execution times and intervals based on this information, and an outputter to execute the defrosting control according to the set schedule, allowing for optimized power usage during designated power saving periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If defrosting control is executed frequently to prevent frost formation, then product quality is maintained, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by obtaining schedule information about upcoming power saving requests and creating an optimized defrosting schedule in advance. The defrosting control is executed before power saving periods begin, ensuring product quality is maintained while minimizing power consumption during high-rate periods.
Solution Approach 2:
The defrosting schedule is made dynamic by adjusting execution timing based on obtained power saving schedule information. The system flexibly modifies when defrosting occurs - executing it during normal power rate periods rather than fixed intervals - to adapt to changing power consumption requirements while maintaining effectiveness.
2Use of energy by moving object
If defrosting control is delayed to reduce power consumption, then power saving is achieved, but frost formation occurs affecting product quality
Solution Approach 1:
The system executes defrosting control as a preliminary action before power saving periods begin. By obtaining schedule information in advance and planning defrosting execution during normal power rate periods, the system prevents frost formation that would occur if defrosting were delayed into power saving periods, thus maintaining product quality while achieving power consumption reduction.
3Use of energy by moving object
If defrosting schedule is optimized for power saving, then power consumption is reduced, but control complexity increases
Solution Approach 1:
The control complexity is managed by performing preliminary action - obtaining power saving schedule information and creating the optimized defrosting schedule in advance, before the actual defrosting execution. This upfront planning simplifies the real-time control logic, as the system only needs to follow the pre-determined schedule rather than making complex decisions during power saving periods.

AI summary
A defrosting control system includes an obtainer, a setting unit, and an outputter. The obtainer obtains schedule information indicating whether power saving is scheduled for a temporary power saving request. The setting unit sets a defrosting schedule including an execution time period and an execution interval of defrosting control for refrigeration equipment, based on the schedule information obtained by the obtainer. The outputter outputs an instruction to execute the defrosting control for the refrigeration equipment according to the defrosting schedule set by the setting unit.
