Abstract

The invention discloses a VRF (Variable Refrigerant Flow)air-conditioner fault handling method which comprises the following steps: an air-conditioner acquires fault information and determines the grade of the fault information; the fault information and the grade thereof are uploaded to a server, so that the server sends an emergency instruction of service in derated capacity back to the air-conditioner when determining that the fault information is in the preset first grade; the air-conditioner operates according to preset safety parameters when receiving the emergency instruction of service in derated capacity and enters a fault halt state after operating for a preset period of time. The VRF air-conditioner fault handling method facilitates the maintenance work of maintenance personnel and improves the service efficiency of a VRF air-conditioner.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a multi-connected air conditioner fault handling method and an air conditioner. Background technique [0002] The multi-connected air-conditioning system has the advantages of high control efficiency and low operating cost, so it is more and more sought after by people. The multi-connected air conditioning system is composed of one outdoor unit or multiple outdoor units connected to multiple indoor units, or an air conditioning system composed of multiple compressors connected in parallel. [0003] In the traditional multi-connected air-conditioning system, as long as the external unit fails, the entire multi-connected air-conditioning system will trigger a protection program to shut down the entire multi-connected air-conditioning system. At this point, maintenance personnel need to perform maintenance on the malfunctioning multi-connected air conditioner. When there are many f...
