Embodiment Construction

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] According to the refrigerant content prediction method used in refrigeration systems of the present invention, it 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 data through the static perfusion test , 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 model with the method of predicting the remaining service life of the refrigeration system through the temperature of the refrigeration system, the refrigerant of the refrigeration system can be obtained content, collect the effective degradat...

Abstract

The invention relates to a refrigerant content prediction method for a refrigeration system. The method comprises a modeling implementation process and a prediction implementation process. In an implementation condition setting method, a measuring point position and an operation condition are determined. Modeling data are obtained through a static perfusion test; A relation model of temperature parameter change and refrigerant content of a refrigeration system is established; The prediction implementation condition is determined, the working mode is selected, the residual service life of the refrigeration system is predicted through the temperature of the refrigeration system in combination with the model, the refrigerant content of the refrigeration system is obtained, the effective degradation value of the refrigerant content is collected, and the residual service life of the refrigeration system is obtained.

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...
