Abstract

The invention discloses a power supply control device, method and multi-connected air conditioning system. Wherein, the power supply control device includes: an adapter and a controller, the adapter is respectively connected to the first power supply and the mains power supply, and is used to control the power supply from the first power supply when the mains power supply is cut off; the adapter includes: a detection voltage output terminal , connected to the power supply detection module of the controller to indicate whether it is powered by the first power supply; at least one power supply voltage output terminal is connected to the power supply control module of the controller. The invention outputs multiple voltages through the adapter to meet the power supply requirements of the load; through the detection voltage output terminal of the adapter and the power supply detection module of the controller, the controller can identify whether it is powered by the first power supply, so as to perform corresponding processing under the power supply of the first power supply . There is no need to change the original power circuit of the controller, no need to detect the strong current circuit, the structure is simple, and it can conveniently, intelligently and efficiently realize the power supply switching control when the mains power is cut off, and maintain the normal operation of the system.

Description

technical field [0001] The present invention relates to the technical field of power supply control, and in particular, to a power supply control device, a method, and a multi-connected air conditioning system. Background technique [0002] In a multi-connected air conditioning system, when some indoor units are powered off and offline, loads such as electronic expansion valves are out of control, resulting in uncontrolled refrigeration systems and abnormal operation. [0003] At present, in view of the above problems, the backup power supply is generally used for additional power supply, and the backup power supply is directly connected to the controller. Electric power grid, the structure is more complex, not intelligent and efficient enough. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a power supply control device, a method, and a multi-connected air conditioning system, so as to at least solve the problems of complex and inefficient ...
