A load identification method, device, storage medium and compressor

Abstract

The invention discloses a load identification method, device, storage medium and compressor. The method includes: obtaining the stiffness of the compressor pipeline connection, and obtaining the vibration response of the set point of the compressor pipeline connection; The product of the stiffness and the vibration response is determined as the load at the compressor pipeline connection; wherein the compressor pipeline connection is the connection between the compressor and its pipeline system; the set point includes: Under the set working conditions of the external unit of the air conditioner to which the compressor belongs, the connection point between the compressor suction port and the pipeline at each operating frequency, and / or the connection point between the compressor exhaust port and the pipeline at each operating frequency. The scheme of the present invention can solve the problem of difficulty in obtaining the compressor excitation, and achieve the effect of reducing the difficulty in obtaining.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, 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 by the dynamic model of the compressor. 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 accurate values ​​of various parameters, and it is very difficult to obtain accurate values ​​of some parameters, such as 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 more di...
