The invention provides a refrigeration system simulation method and device. The method comprises the following steps of: obtaining N groups of experimental data of a to-be-simulated refrigeration system; carrying out simulation through N groups of actually measured pressure drop data to obtain N groups of simulation flow data and N first intermediate pressure drop coefficients, and carrying out fitting through the N first intermediate pressure drop coefficients to obtain a first pressure drop coefficient; carrying out simulation through the N groups of actually measured pressure drop data to obtain N groups of simulation pressure drop data and N second intermediate pressure drop coefficients, and carrying out fitting through the N second intermediate pressure drop coefficients to obtain a second pressure drop coefficient; determining whether a deviation between the first pressure drop coefficient and the second pressure drop coefficient is less than a preset deviation threshold value or not, and if the deviation between the first pressure drop coefficient and the second pressure drop coefficient is less than the preset deviation threshold value, taking an average value of the first pressure drop coefficient and the second pressure drop coefficient as a pressure drop coefficient in a connection pipe; and carrying out refrigeration system simulation on the basis of the pressure drop coefficient in the connection pipe. Relative to the conventional manners of determining coefficients according to experience parameters, the method and device provided by the invention have the advantage of effectively improving the precision of refrigeration simulation software.
Description
technical field [0001] The invention relates to the technical field of simulation analysis, in particular to a refrigeration system simulation method and device. Background technique [0002] At present, the formulas used in all refrigeration simulation systems are basically the same. The only difference is the processing and setting of the coefficients in the formulas. These coefficients are also the most important factors that directly affect the simulation accuracy. [0003] However, the existing coefficients are generally determined based on empirical parameters, which leads to a large accuracy of refrigeration simulation software. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] An embodiment of the present invention provides a refrigeration system simulation method to improve the accuracy of refrigeration simulation software, the method comprising: [0006] Obtain N sets of experimental data of the ref...
