Method and device of load identification, storage medium and compressor

Abstract

The invention discloses a method and device of load identification, a storage medium and a compressor. The method comprises the following steps that the rigidity of a pipeline connection position of the compressor is acquired, and a vibration response of a setting point at the pipeline connection position of the compressor is acquired; and the product of the rigidity and the vibration response is determined to be the load of the pipeline connection part of the compressor, wherein the pipeline connection position of the compressor is the connection position of the compressor and a pipeline system of the compressor; and the setting point comprises the connection point of an air suction port and the pipeline of the compressor under operation frequencies, and / or the connecting point of an exhaust port and the pipeline of the compressor under the operation frequencies when the compressor belonging to an air conditioner outdoor unit in the set working condition. According to the scheme, the problem that the difficulty of obtaining the excitation of the compressor is large can be solved, and the effect of reducing the obtaining difficulty is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a load identification method, device, storage medium and compressor, and in particular to a load identification method, device, storage medium and compressor of an air conditioner compressor piping system. Background technique [0002] At present, the excitation force of the compressor is usually calculated from the compressor dynamics model. The calculation parameters mainly include the aerodynamic torque load, the electromagnetic torque load of the motor, and the eccentric load of the rotor dynamic balance. The main disadvantage of this method is that it is necessary to obtain the precise values ​​of each parameter, and it is very difficult to obtain the precise value of some parameters, such as the gas torque load. In some cases, the compressor is supplied by a third party, and the internal model and parameters cannot be obtained. Therefore, it is difficul...
