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 a detection method and device of an air conditioner, and the air conditioner, wherein the detection method of the air conditioner includes: responding to the control command of the trial operation, controlling the start-up of multiple indoor units, and controlling the operation of the outdoor units according to the preset operation mode ; Detect the connection between any pipeline in the refrigerant distribution device and multiple indoor units to obtain the detection results, and determine the communication control relationship and relationship between the outdoor unit, multiple indoor units and the refrigerant distribution device through the obtained detection results Whether the connection relationship of the refrigerant pipeline is consistent, so as to correct the installation error caused by improper installation operation or unfamiliarity with the installation process during the installation process of the air conditioner, thereby improving the reliability of the air conditioner operation.

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...
