Problems solved by technology

[0003] In the related technical solutions, the refrigerant distribution device needs to be connected to multiple indoor units. In the actual installation process, due to the unfamiliarity with the system to be installed, the wiring is complicated, and installation abnormalities are prone to occur, such as outdoor units, multiple indoor units and refrigerant The communication control relationship of the distribution device is inconsistent with the connection relationship of the refrigerant pipeline, and the on-site installation engineer cannot intuitively judge whether the communication control relationship and the connection relationship are consistent. Therefore, installation errors are prone to occur during the installation process of the central air conditioner. The reliability of the system operation is low

Abstract

The invention provides an air conditioner detection method, an air conditioner detection device and an air conditioner, wherein the air conditioner detection method comprises the following steps: in response to a control command of pilot run, controlling a plurality of indoor units to start, and controlling an outdoor unit to run according to a preset running mode; detecting situation of connection between any pipeline of a refrigerant dividing device and the plurality of indoor units, thereby obtaining a detection result, confirming whether a communication control relation of the outdoor unit, the plurality of indoor units and the refrigerant dividing device is consistent with a connection relation of a refrigerant pipeline according to the obtained detection result so as to correct installation errors of the air conditioner caused by improper installation operations or unfamiliarity with installation procedures in an installation process, and consequently improving reliability of running of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to a detection method and device for an air-conditioner and the air-conditioner. Background technique [0002] The central air-conditioning multi-connected system is a typical HVAC equipment system, which includes an outdoor unit, multiple indoor units, and a refrigerant distribution device connected between the outdoor unit and multiple indoor units. Among them, The refrigerant distribution device can be used to distribute the refrigerant output from the outdoor unit to the indoor unit. Among them, the refrigerant distribution device can be divided into one or more, and it is mainly used to distinguish the number of groups of indoor units. For example, the common One divides one, one divides two, one divides four, one divides six, one divides eight, one divides twelve, etc., that is, one to twelve groups of internal units can be controlled under one refrigerant div...
