and controlling the electronic expansion valve of the indoor unit with the incapability requirement to be opened to a set opening degree, and recovering to a normal control mode after the electronic expansion valve is continuously set for a set time, wherein the set opening degree is not 0, and the set time is not 0.
8. The control device of claim 6, wherein the control module is specifically configured to:
detecting that the multi-split air conditioning system meets the condition of entering a refrigerant-media-resistant abnormal sound control mode;
and controlling the opening degree of the electronic expansion valve of the indoor unit with the incapability requirement.
9. The control device according to claim 8, wherein the refrigerant abnormal sound prevention control mode entering condition includes the following condition:
the multi-split air conditioning system is in a refrigeration or dehumidification mode;
the number of indoor units which have the capacity of being required in the multi-split air conditioning system is not more than a set number, and the set number is not 0; and the number of the first and second groups,
the highest damper of the indoor unit with the capacity requirement is a set damper when the indoor unit is started.
10. The control device of claim 8, wherein the control module is further configured to:
detecting that the multi-split air conditioning system does not meet the entry condition of the anti-cold-medium abnormal sound control mode;
and controlling the electronic expansion valve of the indoor unit with the incapability requirement to recover to a normal control mode.
11. A multi-split air conditioning system, comprising: the control device of a multi-split air conditioning system as set forth in any one of claims 6 to 10.
12. An electronic device, comprising: a memory, a processor, and a computer program stored on the memory and executable on the processor, the processor implementing the control method of the multi-split air conditioning system as set forth in any one of claims 1 to 5 when executing the program.
13. A computer-readable storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements a control method of a multi-split air conditioning system as set forth in any one of claims 1 to 5.
