Pipeline stress control method and air conditioner control system

Abstract

The invention provides a pipeline stress control method and an air conditioner control system. The method comprises the following steps that pipeline stress values are obtained, the operation frequency of a compressor is controlled according to the stress values, the obtained pipeline stress values comprise a start-stage pipeline stress value and an operation-stage pipeline stress value, accordingto an existing condition of an air conditioning unit, the pipeline stress values are divided into the start-stage pipeline stress value and the operation-stage pipeline stress value, due to the different working conditions of the compressor in the start-stage and the operation-stage, the pipeline stress values are divided, the compressor is more accurately adjusted, pipeline damage caused by stress value increase is avoided, the stress is obtained by arranging a stress sensor on a specific pipeline so that the stress value on the pipeline can be detected in real time by the stress sensor, anda reference is provided for adjusting the compressor; and the stress sensor is preferably arranged on a pipeline connected with an air suction port or a pipeline connected with an air exhaust port ofthe compressor, and when the stress value exceeds the preset requirement, the frequency point of the compressor can be skipped at the time, and pipeline cracking and leakage are avoided.

Description

Technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a pipeline stress control method and an air conditioning control system. Background technique [0002] Air conditioning unit, due to the mechanical vibration of the compressor, the refrigerant flow in the system and the change of the state, the pipeline will vibrate. Part of the pipeline, especially the pipeline connected to the compressor suction port or exhaust port, the vibration is especially Large, and there is a local stress concentration situation, which may cause the pipeline to break. At present, in order to solve such problems, air-conditioning manufacturers mainly adopt the strategy of optimizing the pipeline design and shielding the state points with increased vibration or stress. That is, during development, test the pipeline stress and shield the state points with greater stress. When the compressor is running, skip this frequency. It is superior to the limite...
