Automatic matching method for indoor unit and outdoor unit compressors

Abstract

The invention discloses an automatic matching method for indoor unit and outdoor unit compressors. The automatic matching method comprises the following steps: starting one compressor while controlling a plurality of operation refrigeration mode of an indoor unit through an outdoor unit control board, determining that the compressor is possibly matched with the indoor unit if the temperature drop range of the indoor unit is greater than a preset temperature; then, controlling a plurality of operation heating modes of the indoor unit through the outdoor unit control board, determining that the compressor is successfully matched with the indoor unit if the temperature increase range of the indoor unit is greater than a preset temperature, closing the compressor and the indoor unit, and repeating the steps until all compressors and indoor units are successfully matched. According to the automatic matching method, the mounting difficulty and the mounting time of an air-conditioning system can be effectively reduced; software is not required to be artificially configured, so that a mounting process is simplified, an air-conditioning mounting error ratio is reduced, and automation degree of the air conditioner is improved.

Description

Technical field [0001] The invention involves the field of refrigeration technology, and it specially involves an automatic matching method of indoor and outdoor compressors. Background technique [0002] There is an outdoor and multiple indoor machines in a air -conditioning system, and there is only one outdoor unit control board in the outdoor unit to control multiple compressors.Compressor.Therefore, the corresponding relationship between the indoor machine and the compressor connected to it has a one -to -one correspondence, so that the compressor can be controlled accurately when indoor machines have refrigeration or heating demand. [0003] At present, there are two main technologies for matching methods of indoor machines and outdoor machine compressors: [0004] One: On -site technicians correspond to different compressors according to the different control ports of the outdoor control board, check different compressors to connect to the refrigerant of different indoor m...

Problems solved by technology

The advantage of this matching method is that there is no need to set anything through the external controller, but it will increase the difficulty of installation and the probability of installation errors

[0006] To sum up, since the indoor units and compressors in the air conditioning system must have one-to-one correspondence in control, in order to enable the software to identify different compressors corresponding to different indoor units, it is necessary for on-site installation technicians to pass specific installation or software The configuration method is used to establish the corresponding mapping relationship between the indoor unit and the compressor on the software, which will inevitably make the installation process complicated, and may also need to configure the software or control board, so it will cause long installation time and error-prone phenomena.
