A method for automatic matching of indoor unit and outdoor unit compressors

Abstract

The invention discloses a method for automatically matching the compressors of an indoor unit and an outdoor unit. The control board of the outdoor unit controls multiple indoor units to operate in the refrigeration mode and at the same time turns on one compressor. When the temperature drop range of one of the indoor units is greater than the preset temperature, it is considered that the compressor and the indoor unit may match; then control multiple indoor units to run in heating mode through the outdoor unit control board, if the temperature rise range of the indoor unit is greater than the preset temperature, it is considered that the compressor and the indoor unit If the matching is successful, turn off the compressor and indoor unit, and repeat the above steps until all compressors and indoor units are successfully matched. The invention can effectively reduce the installation difficulty and installation time of the air-conditioning system, simplify the installation process, reduce the error rate of the air-conditioning installation, and improve the automation degree of the air-conditioning system because no manual configuration of software is required.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an automatic matching method for an indoor unit and an outdoor unit compressor. Background technique [0002] There are one outdoor unit and multiple indoor units in an air conditioning system, and there is only one outdoor unit control panel in the outdoor unit to control multiple compressors, and the cooling and heating needs of each indoor unit can only depend on one of them having a refrigerant connection with it of the compressor. Therefore, a one-to-one correspondence between the indoor unit and the compressor connected with the refrigerant should be established, so that the compressor can be accurately controlled when the indoor unit has a cooling or heating demand. [0003] At present, there are mainly two matching methods of the indoor unit and the outdoor unit compressor in the existing technology: [0004] One: The on-site technicians correspond to different co...

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.
