  • Publication number: 20240426498
    Abstract: A multi-split air-conditioning system, a fault positioning method, and a fault diagnosis model training method are provided. The multi-split air-conditioning system includes an outdoor unit, a plurality of indoor units, a plurality of electronic expansion valves, and a controller. The controller is configured to: obtain feature data of each of the plurality of indoor units in a case where an electronic expansion valve in the multi-split air-conditioning system is faulty, the feature data including a temperature difference between a temperature value of a liquid pipe correspondingly connected to the indoor unit and a temperature value of an air pipe correspondingly connected to the indoor unit; determine an abnormal indoor unit in the plurality of indoor units according to the feature data of each of the plurality of indoor units; and determine the electronic expansion valve corresponding to the abnormal indoor unit as a faulty electronic expansion valve.

  • Publication number: 20230375210
    Abstract: An air conditioner system includes an air conditioner and a cloud platform. The air conditioner includes an indoor unit and an outdoor unit. The cloud platform is configured to: in a case where the air conditioner is in a heating mode, determine that the outdoor unit performs one of defrosting and ending defrosting; if determining that operating parameters of the outdoor unit satisfy a first preset condition, send a first sub-instruction to the outdoor unit, so that the outdoor unit starts defrosting according to the first sub-instruction; if determining that the operating parameters satisfy any one of a plurality of second preset conditions, send a second sub-instruction to the outdoor unit, so that the outdoor unit ends defrosting according to the second sub-instruction.
