Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigerator cooling systems have a constant amount of refrigerant, which leads to inefficient operation due to changing environmental conditions and load, resulting in increased compressor workload, energy consumption, and poor refrigerating effects.
Innovation Solution
A refrigerator cooling system with a refrigerant amount regulator that includes a storage device and an adjustor with a sealer to automatically adjust the refrigerant flow by opening or closing a communication opening between the storage device and the pipe loop, using an electromagnet and spring mechanism for controlled operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the amount of refrigerant is kept constant in the cooling system, then the system structure is simple, but the refrigerating efficiency decreases when environment temperature or load conditions change
Solution Approach 1:
The patent applies the dynamics principle by making the refrigerant amount adjustable rather than fixed. A refrigerant amount regulator with a storage cavity and controllable opening allows the refrigerant quantity in the system to be dynamically adjusted according to environmental temperature and load conditions, resolving the contradiction between structural simplicity and refrigerating efficiency.
2Productivity
If the refrigerant amount is increased to meet high refrigerating demand, then the refrigerating effect improves, but the compressor workload increases and service life decreases
Solution Approach 1:
The patent implements feedback control through a controller that monitors environmental temperature and refrigerating demand, then automatically adjusts the refrigerant amount regulator accordingly. This feedback mechanism ensures the refrigerant amount is optimized for current conditions, improving refrigerating effect while preventing excessive compressor workload that would reduce service life.
