Compressor Non-Volatile Memory for Persistent Configuration Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressor data is often lost when protection and control systems are replaced or disconnected from compressors, leading to operational issues and requiring reinstallation, which can result in errors and inefficiencies in refrigeration systems.
Innovation Solution
A compressor with a non-volatile memory system, including a processor and a connector block, that stores and retrieves compressor-specific data such as model type, capacity, and operating coefficients, ensuring data persistence even when the system is disconnected, using RFID devices or tamper-resistant housings for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressor data is stored in external protection and control systems, then data can be accessed during operation, but data is lost when systems are replaced or disconnected
Solution Approach 1:
The patent extracts the critical compressor data storage function from the external protection and control system and places it directly within the compressor unit itself. This is achieved through embedding non-volatile memory in the compressor's connector block or housing, ensuring data remains with the compressor regardless of external system changes.
Solution Approach 2:
The patent implements data redundancy by maintaining copies of compressor data in multiple locations: the embedded non-volatile memory within the compressor, and simultaneously in the external protection and control system. This copying approach ensures data availability even if one storage location fails or is replaced.
2Adaptability or versatility
If installer manually loads compressor data in field, then system can be configured for specific compressor, but errors occur and data may be lost
Solution Approach 1:
The patent applies preliminary action by pre-loading compressor data during the manufacturing process directly into non-volatile memory embedded in the compressor. This eliminates the need for field installation of data, as the data is already accurately configured before the compressor leaves the factory. The data includes compressor-specific parameters such as capacity, model type, and operating coefficients.
3Ease of repair
If protection and control system is replaced, then system can be upgraded or repaired, but compressor data must be reloaded
Solution Approach 1:
The patent separates the data storage function from the protection and control system by embedding it directly in the compressor. This extraction allows the protection and control system to be replaced, upgraded, or repaired independently without affecting the stored compressor data, which remains safely embedded in the compressor's connector block or housing.
4Reliability
If data is stored securely in compressor, then data protection is improved, but access complexity increases
Solution Approach 1:
The patent merges the data storage function with the compressor's existing structural components by embedding non-volatile memory directly into the connector block or housing. This integration approach provides secure data storage within the compressor while utilizing existing physical structures, thereby minimizing additional complexity. The memory is accessed through standard communication protocols already present in the system.

AI summary
A method includes accessing a first non-volatile memory associated with a compressor using a processor associated with at least one of a second non-volatile memory and an operating memory. A method further includes storing compressor data from at least one of the second non-volatile memory and the operating memory in the first non-volatile memory and accessing the compressor data in the first non-volatile memory to evaluate compressor performance.
