An adaptive control method and system for air conditioner pressure switch wiring

Abstract

The invention relates to an air conditioner pressure switch wiring self-adaption control method and system. The air conditioner pressure switch wiring self-adaption control system comprises a central controller, a compressor, an indoor motor and an outdoor motor, the central controller is electrically connected with the compressor, the indoor motor and the outdoor motor, and one side of the compressor is provided with a low-pressure switch, and the other side of the compressor is provided with a high-pressure switch. The air conditioner pressure switch wiring self-adaption control method and system are characterized in that the central controller is provided with a first pressure switch connector and a second pressure switch connector, a connector of the low-pressure switch can be connected with any one of the first pressure switch connector and the second pressure switch connector, and a connector of the high-pressure switch can be connected with the other one of the first pressure switch connector and the second pressure switch connector; the central controller can automatically distinguish the low-pressure switch and the high-pressure switch by controlling operation or stopping of the compressor, the indoor motor and the outdoor motor. Compared with the prior art, the air conditioner pressure switch wiring self-adaption control method and system have the advantages that the high-pressure switch and the low-pressure switch do not need to be distinguished through colors, limitation of the shapes of the high-pressure switch and the low-pressure switch is avoided, and the high-pressure switch and the low-pressure switch can be automatically distinguished.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an adaptive control method and system for the wiring of an air conditioner pressure switch. Background technique [0002] In the field of household air conditioner manufacturing, household air conditioners mainly include compressors, condensers, throttling devices, and evaporators, as well as auxiliary components such as stop valves. Among them, compressors are the core components of air conditioners. There is a low-pressure switch on the suction side of the compressor, which protects when the pressure on the suction side is too low. There is a high-pressure switch on the discharge side of the compressor, which protects when the pressure on the discharge side is too high. The air-conditioning pressure switch is used to detect the air-conditioning pipeline Then the pressure signal is sent to the air conditioner control system to protect the air conditioner compressor and pipeline. ...

[0002] In the field of household air conditioner manufacturing, household air conditioners mainly include compressors, condensers, throttling devices, and evaporators, as well as auxiliary components such as stop valves. Among them, compressors are the core components of air conditioners. There is a low-pressure switch on the suction side of the compressor, which protects when the pressure on the suction side is too low. There is a high-pressure switch on the discharge side of the compressor, which protects when the pressure on the discharge side is too high. The air-conditioning pressure switch is used to detect the air-conditioning pipeline Then the pressure signal is sent to the air conditioner control system to protect the air conditioner compressor and pipeline. Only when the pressure signal is within the normal range can the air conditioner work normally. The current high pressure switch, low pressure switch shape, The types of terminal blocks are almost the same, they are all copper inserts of 6.3mm*0.8mm, which makes it easy for workers to reverse the high-voltage switch and low-voltage switch wires when wiring.

[0003] The current practice in the industry is to distinguish wire harnesses of different colors, such as white wires for low-voltage switches and red wires for high-voltage switches; although the color distinction is eye-catching, it is convenient for production plugging and future maintenance and inspection of wires, but it still requires manual labor. Make a judgment. If the worker has a weak sense of responsibility or is negligent, compressor wiring errors often occur during the production process, and wiring errors are also common in the daily air conditioner test assembly and maintenance process. The serious consequences of compressor wiring errors are The whole compressor burned out and the air conditioner didn't work properly

[0004] In order to solve the above-mentioned technical problems, a pressure switch detection device has appeared, such as the Chinese invention patent "A Pressure Switch Detection Device for Automobile Air Conditioning" whose patent number is CN201420319230.X (authorized announcement number is CN203941272U). plate, the workbench frame includes a bracket and a workbench, and the baffle is arranged on three sides of the workbench, and it is characterized in that: the workbench is provided with a pressure detection device and a circuit detection device, and the pressure detection device realizes The detection of low pressure and high pressure of the pressure switch is convenient for detecting the sensitivity of the pressure switch when the low pressure and high pressure are switched in a short period of time, but when the pressure switch is connected incorrectly, it is still necessary to switch the low pressure and high pressure, which is time-consuming and inconvenient to detect
