Abstract

The present invention provides an operation control method, an operation control device, an air conditioner, and a storage medium, wherein the operation control method includes: detecting a working condition parameter of a second air return port, and determining a corresponding saturation threshold according to the working condition parameter; According to the comparison result between the operating condition parameter and the saturation threshold, an adjustment parameter of the air conditioner system is generated, and the adjustment parameter is used to adjust the air-liquid separator and the second air return port. Refrigerant flow. Through the technical solution of the present invention, the liquid shock risk to the compressor is reduced by reducing the refrigerant flow rate between the gas-liquid separator and the second air return port, so that the refrigerant at the second air return port is in an overheated state, which is conducive to improving the air conditioner. The stability and security of the system operation.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] In the related technology, in order to improve the energy efficiency of the system, the independent compression system is equipped with a gas-liquid separator to separate the gaseous refrigerant and the liquid refrigerant passing through the condenser, wherein the gaseous refrigerant is directly introduced into the compressor, and the liquid refrigerant is introduced into the evaporator. Therefore, while reducing the power consumption of the compressor, the heat exchange efficiency is improved, but there are the following defects: [0003] In the system start-up state or other unstable states, the gas-liquid separator is prone to full liquid, resulting in the risk of liquid shock to the compressor.
