Title:
MUFFLER PARAMETER DETERMINATION METHOD AND APPARATUS, DEVICE, STORAGE MEDIUM, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/051179
Kind Code:
A1
Abstract:
A muffler parameter determination method and apparatus, a device, a storage medium and a system, the method comprising: acquiring the temperature value and the pressure value of a refrigerant, the proportion of a gas refrigerant and the proportion of a liquid refrigerant in a compressor pipe; then on the basis of the temperature value and the pressure value, determining the density of the gas refrigerant, the density of the liquid refrigerant, a sound propagation speed in the gas refrigerant and a sound propagation speed in the liquid refrigerant; on the basis of the proportion of the gas refrigerant, the proportion of the liquid refrigerant, the density of the gas refrigerant, the density of the liquid refrigerant, the sound propagation speed in the gas refrigerant and the sound propagation speed in the liquid refrigerant, determining a sound propagation speed in the compressor pipe; determining a correction factor for the sound propagation speed in the compressor pipe on the basis of the proportion of the liquid refrigerant, and correcting the sound propagation speed in the compressor pipe on the basis of the correction factor; and, on the basis of the corrected sound propagation speed in the compressor pipe and the frequency of the noise having the maximum amplitude value, determining the length of a muffler.
