Refrigerant Content Prediction Method for Refrigeration System

Abstract

The invention relates to a refrigerant content prediction method for a refrigeration system, which is divided into a modeling implementation process and a prediction implementation process, which sets the implementation conditions, determines the location of the measuring point and the operating condition, and obtains the modeling method through a static perfusion test Data, by establishing the relationship model between the temperature parameter change and the refrigerant content of the refrigeration system, determining the forecast implementation conditions, selecting the working mode, and combining the above models with the method of predicting the remaining service life of the refrigeration system through the temperature of the refrigeration system, the refrigeration system’s refrigeration capacity can be obtained. Collect the effective degradation value of the refrigerant content to obtain the remaining service life of the refrigeration system.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a refrigerant content prediction method for refrigeration systems. Background technique [0002] With the increasing complexity of the refrigeration system, most of the fault inspection and maintenance are carried out on site by technicians or mechanics, so the traditional fault diagnosis and maintenance become extremely time-consuming and expensive, fault diagnosis, equipment maintenance and life estimation have been From starting to deal with failures to developing preventive maintenance based on predicted results during the work process. Preventive maintenance and diagnosis do not require frequent on-site repetitive work through reliability and prediction technology, and its prediction frequency can be changed according to the severity of the application and the operating environment, which can effectively increase the efficiency of fault inspection and maintenan...
