Abstract
Description
Technical Field
[0001] The invention relates to the technical field of compressor maintenance and discloses a compressor cooling health management system and method. Background Art
[0002] Although the health management of compressor cooling systems has made significant technological progress, it still faces many challenges and room for improvement, especially in terms of data processing, prediction accuracy, cost-effectiveness balance and technology integration, which require continuous optimization and improvement. The cost of establishing and maintaining a compressor health management system may be high, especially for small and medium-sized enterprises, which may require a balance between input and benefits. Most of the market adopts physical thermal management, and there is still room for improvement in the accuracy of prediction and diagnosis, especially in complex working conditions and changing environments. It is difficult to update the compressor temperature and voltage changes in real time, which greatly increases the compressor failure rate and reduces the life of the compressor, increasing the company's later maintenance costs. At this time, there is an urgent need for a compressor cooling health management system that can solve real-time monitoring and performance evaluation through an algorithm model and automatically generate control strategies.
[0003] For example, the existing Chinese patent with publication number CN115962590A provides an air-replenishing enthalpy-increasing energy storage thermal management system in which an intermediate refrigerant is first cooled and then evaporated, including: a compressor; a heat exchange device, which is configured to be connected between the compressor and the intermediate heat exchange device; the intermediate heat exchange device is configured to output the refrigerant in two ways, wherein the first part of the refrigerant returns to the intermediate heat exchange device to evaporate, to take away part of the heat of the second part of the refrigerant and then directly returns to the compressor, and the second part of the refrigerant cooperates with the heat exchange device to exchange heat and then returns to the compressor.
[0004] However, the above patent has the following problems: the thermal management system of the compressor mainly monitors data through physical monitoring, and controls temperature through physical cooling;
[0005] Although the above-mentioned refrigerant heat exchange system has optimized thermal management in hardware, its response speed and flexibility are not as good as those of the artificial intelligence control system when faced with rapidly changing operating conditions. In addition, the physical heat exchange system lacks this intelligent adaptive capability, making it difficult to perform dynamic optimization during operation. Summary of the invention
