Abstract

A noise control method, device, multi-connected air-conditioning system and storage medium provided by the present invention relate to the technical field of air conditioners. During the heating operation of the multi-connected air-conditioning system, the operating data of the compressor is obtained according to a preset time interval, and passed The operating data calculates the current adiabatic variable index of the multi-connected air-conditioning system; if the current adiabatic variable index is greater than or equal to the ideal adiabatic variable index, it indicates that the flowing refrigerant in the multi-connected air-conditioning system is insufficient at this time. If the expansion valve of the indoor unit is at the first opening degree, then adjust the fan of the indoor unit when the temperature is shut down from the low gear to off, and increase the expansion valve of the indoor unit when the temperature is shut down from the first opening to the second opening. To supplement the flowing refrigerant in the multi-connected air-conditioning system and ensure the heating reliability of the multi-connected air-conditioning system. In this way, the heating effect of the multi-connected air-conditioning system can be guaranteed while reducing noise.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a noise control method and device, a multi-connected air conditioner system and a storage medium. Background technique [0002] At present, when the multi-connected air-conditioning system is heating, in order to avoid the accumulation of refrigerant in the indoor unit when the temperature is shut down, the expansion valve of the indoor unit when the temperature is shut down is often kept at a certain opening, so that the indoor unit when the temperature is shut down is not running. Refrigerant sound comes out, affecting user experience. [0003] In order to solve this problem, usually the expansion valve of the internal machine in warm shutdown is turned down or even closed, so that the internal machine in warm shutdown makes a small refrigerant sound or even mutes. However, this will lead to insufficient flowing refrigerant in the multi-connected air-condition...
