Embodiment Construction
[0029] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] The solution of the embodiment of the present invention is mainly as follows: the indoor unit of the multi-connected air-conditioning system includes a plurality of indoor heat exchangers, and the inlet and outlet of at least one indoor heat exchanger are respectively connected to solenoid valves. When the electromagnetic valve is opened, the corresponding indoor heat exchanger operates normally, and when the electromagnetic valve is closed, the corresponding indoor heat exchanger does not operate, thereby reducing the load of the multi-connected air conditioning system, without the need Avoid overloading the multi-split air conditioning system by shutting it down. Through the technical solutions of the embodiments of the present invention, the problem of low reliability in the operation of the multi-connected ...

The invention discloses a multi-split air conditioning system. The multi-split air conditioning system comprises one or more outdoor units and multiple indoor units. The multi-split air conditioning system is characterized in that each indoor unit comprises multiple indoor heat exchangers and multiple solenoid valves, wherein the indoor heat exchangers are in parallel connection, and the multiplesolenoid valves are connected with inlets and outlets of the corresponding indoor heat exchangers; and the multi-split air conditioning system further comprises a controller, the controller is used for controlling the multiple solenoid valves to be switched on and switched off and controlling the corresponding indoor heat exchangers to stop heat exchange operation when the multiple solenoid valvesare switched off, so that the load of the multi-split air conditioning system is lowered. The invention further discloses a control method and device of the multi-split air conditioning system and acomputer readable memory medium. By means of the multi-split air conditioning system, the control method and device thereof and the readable memory medium, operation reliability of the multi-split airconditioning system is improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a multi-connected air conditioner system and its control method, device, and readable storage medium. Background technique [0002] With the development of science and technology, multi-connected air-conditioning systems are gradually being widely used, including indoor units and outdoor units. The number of outdoor units is generally one or more, and the number of indoor units is generally multiple. Each indoor unit includes an The indoor heat exchanger performs indoor heat exchange to realize heating / cooling. In some cases, when the system is overloaded, the outdoor unit is generally turned off to avoid the overload operation of the multi-connected air-conditioning system, that is, shutdown, which makes the multi-connected air-conditioning system unable to continue cooling / heating. Therefore, many The reliability of the combined air-conditioning system needs t...
