Embodiment Construction
[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] Please refer to figure 1 , figure 1 It is a schematic block diagram of a multi-connected air-conditioning system 10 provided by the present invention. The multi-connected air-conditioning system 10 includes a processor 11 , a memory 12 and a plurality of internal units 13 , and the processor 11 is electrically connected to the memory 12 and the plurality of internal units 13 .
[0029] Memory 12 is used to store programs such as Image 6 Noise control device 100 is shown. The noise control device 100 includes at least one software function module that can be stored in the memory 12 in the form of software or firmware (firmware) or solidified in the operating system (operating system, OS) of the multi-connected air-conditioning sys...

The invention provides a noise control method and device, a multi-split air-conditioning system and a storage medium, and relates to the technical field of air conditioners. During heating operation of the multi-split air-conditioning system, operation data of a compressor are obtained according to a preset time interval, and a current adiabatic polytropic index of the multi-split air-conditioningsystem is calculated through the operation data; and if the current adiabatic polytropic index is larger than or equal to an ideal adiabatic polytropic index, it is indicated that a flowing refrigerant in the multi-split air-conditioning system is insufficient at the moment, if an expansion valve of a temperature-reaching shutdown inner unit is at a first opening degree at the moment, a fan of the temperature-reaching shutdown inner unit is adjusted to be stopped from operation at a low wind gear, and the expansion valve of the temperature-reaching shutdown inner unit is increased into a second opening degree from the first opening degree, so that the flowing refrigerant in the multi-split air-conditioning system is supplemented, and the heating reliability of the multi-split air-conditioning system is ensured. Thus the heating effect of the multi-split air-conditioning system is ensured while noise is lowered.
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...
