Embodiment 1

[0095] figure 1 It is a flow chart of the multi-line leak location automatic location method provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0096] S101. Determine that the current running state of the multi-line unit satisfies the leak location location condition.

[0097] Among them, the multi-connection includes multiple outdoor units and multiple indoor units, and one outdoor unit can correspond to one or more indoor units. The multi-line leak location location condition is used to start the leak location (also called leak point) self-diagnosis process. If the current operating status of the multi-line meets the leak location location conditions, it can enter the leak location self-diagnosis process and perform related operations.

[0098] S102. Control each outdoor unit and each indoor unit according to a preset operation, and determine the leakage position of the multi-connection unit accordi...

Embodiment 2

[0155] figure 2 It is a schematic structural diagram of the multi-connection provided by Embodiment 2 of the present invention, such as figure 2As shown, the multi-connection includes multiple outdoor units and multiple indoor units, and each outdoor unit and each indoor unit is provided with its own unique identification information. The corresponding outdoor units are connected to the indoor units through connecting pipelines. In order to realize block detection, valves are set between the outdoor unit and the indoor unit to separate them, such as the valve close to the connecting pipeline of the outdoor unit and the internal unit cut-off solenoid valve of the indoor unit. In this embodiment, whether there is leakage is judged by the amount of pressure attenuation, therefore, pressure sensors are provided in the outdoor unit and the indoor unit. In the outdoor unit, the pipeline between the compressor and the oil-gas separator is a high-pressure pipeline, and the pipelin...

Embodiment 3

[0209] This embodiment provides a multi-line leakage position automatic positioning device, which can be used to implement the multi-line leakage position automatic positioning method described in the above embodiment. Figure 4 It is a structural block diagram of the multi-line leak location automatic positioning device provided by the third embodiment of the present invention, as shown in Figure 4 As shown, the device includes:

[0210] A condition determining module 401, configured to determine that the current operating state of the multi-line meets the leak location location condition;

[0211] Leakage position determination module 402, configured to control each outdoor unit and each indoor unit according to preset operations, and determine the leakage position of the multi-connector according to the diagnostic parameters.

[0212] Optionally, the condition determination module 401 includes:

[0213] a first condition judging unit, configured to judge whether the curr...

Abstract

The invention discloses a multi-split air conditioner leakage position automatic positioning method, device and equipment. The method includes the steps of determining that the current running state of a multi-split air conditioner meets a leakage position positioning condition; and controlling all outdoor units and all indoor units according to the preset operation, and determining the multi-split air conditioner leakage position according to diagnostic parameters. According to the multi-split air conditioner leakage position automatic positioning method, device and equipment, under the condition that the current running state of the multi-split air conditioner meets the leakage position positioning condition, other devices do not need to be used in an assisted manner, automatic and accurate positioning of the leakage position is realized through a control system of a unit per se, relevant information of the leakage position is reported, an after-sales person can conveniently conduct checking and confirmation accurately and efficiently, a complete pre-processing process is formulated before the process from starting to arrival at the site, the time cost of the after-sales maintenance person is saved, and the efficiency of after-sales maintenance is ultimately achieved.

Description

technical field [0001] The present invention relates to the technical field of fault location, in particular to a multi-line leakage location automatic location method, device and equipment. Background technique [0002] Compared with traditional household air conditioners, commercial air source heat pumps have the following advantages: [0003] 1. Compared with the traditional distributed air conditioner and centralized air conditioner system, the multi-connected air conditioner has less initial investment, simple system, flexible use, large radius of action, convenient installation, and safe and reliable operation. [0004] 2. Compared with the central air-conditioning system, the multi-connected air-conditioning unit takes up less space, is flexible to set up, and does not require additional equipment rooms (floors). The outdoor unit can be placed on the roof and other places, which improves the utilization rate of the building area. It does not require specialized perso...
