Cloud multi-connection air conditioning unit and control method thereof

Abstract

The invention provides a cloud multi-connection air conditioning unit. The cloud multi-connection air conditioning unit comprises at least one air conditioning unit body, a cloud multi-connection management platform and a cloud computing platform. An outdoor unit in each air conditioning unit body collects temperature data of an electrolytic capacitor in real time and reports the temperature data and current data; the cloud multi-connection management platform performs central control and management on the outdoor units, receives the temperature data and the current data and reports summarized data; the cloud computing platform completes calculation of the calculated service life of the electrolytic capacitors based on the summarized data and issues the calculated service life to the cloud multi-connection management platform, and the cloud multi-connection management platform carries out real-time monitoring and service life early warning on the electrolytic capacitors according to the calculated service life; and moreover, the cloud multi-connection management platform can also issue current self-adaptive adjustment instructions to the outdoor units according to the calculated service life, and the outdoor units complete the self-adaptive adjustment of the current according to the current self-adaptive adjustment instructions.

Description

technical field [0001] The invention relates to the field of multi-connected air conditioners, in particular to a cloud multi-connected air conditioner and a control method thereof. Background technique [0002] At present, air-conditioning systems or any other inverter drives need to use electrolytic capacitors. The function of electrolytic capacitors is to filter the voltage output by the rectifier circuit, reduce the AC component, and smooth the bus voltage for the inverter. In addition, it can also reduce and absorb the inductance of the motor. The high pulse current of the load reduces the peak voltage of the bus and prevents the instantaneous overshoot or power loss of the bus voltage, which is an important part of the drive circuit of the inverter. The life evaluation of electrolytic capacitors is also a problem that engineers and technicians cannot bypass. The failure of electrolytic capacitors, such as the opening of explosion-proof valves, will cause serious safety...
