Problems solved by technology

When the variable frequency compressor uses the wrong driver software or hardware, the variable frequency compressor may continue to run without reporting a fault. If the variable frequency compressor runs for a long time, this may affect the output capacity of the compressor and fail demand, or even damage and burn the compressor

Embodiment 1

[0025] refer to figure 1 , in this embodiment, a main control system of an outdoor unit of an air conditioner includes a main control module of an outdoor unit and two drive modules for controlling the compressor, wherein the two drive modules are respectively connected to the In the main control module of the outdoor unit; each drive module is connected to a compressor through a three-phase power cable. The main control module of the outdoor unit is equipped with an outdoor dialing device, and the outdoor unit main control module determines the model of the outdoor unit program to be run by inputting the first code in the outdoor dialing device.

[0026] refer to figure 2 , in this embodiment, the control method includes the following steps:

[0027] Step S1: After the outdoor unit is powered on and runs the main control module of the outdoor unit, enter a first code in the outdoor dial device, so that the main control module of the outdoor unit determines that the model o...

Embodiment 2

[0033] refer to image 3 , the difference between this embodiment and Embodiment 1 is that a main control system of an outdoor unit of an inverter air conditioner includes an outdoor unit main control module and a drive module, wherein the outdoor unit main control module determines to run the No. 001 outdoor unit program and is preset with two communication ports; the drive module determines the program of compressor A to be run in step S2. When step S3 is executed, the main control module of the outdoor unit detects that only the drive module connected with the program of the compressor No. A is connected, so that the compressor remains shut down, and the main control module of the outdoor unit stops running. At this time, it is necessary to connect an additional drive module to set the B-number compressor program, and then make the outdoor main control module run from step S1 again, so as to ensure that the number of drive modules is the same as the number of compressors in...

Abstract

The invention discloses a main control program of an outdoor unit of an air conditioner and a control method for identifying a compressor. Generally, in a multi-connected air conditioner, there are multiple outdoor units of different models in the same series of multi-connected air conditioners, and each type of outdoor unit There are differences in the type and quantity of inverter compressors. When the variable frequency compressor uses the wrong driver software or hardware, the variable frequency compressor may continue to run without reporting a fault. If the variable frequency compressor runs for a long time, this may affect the output capacity of the compressor and fail need. A main control system of an outdoor unit of an air conditioner and a control method for identifying a compressor. Steps S1 and S2 are used to input and determine the model of the outdoor unit program and the model of the compressor program respectively; Whether there is an error in the model, so as to ensure that the software part is set correctly; check whether there is an error in the model of the connected compressor through step S5, to ensure that the hardware part is set correctly; through S1 and S3, ensure that the number of drive modules is correct.

Description

technical field [0001] The invention relates to the technical field of air conditioner outdoor units, in particular to a main control system of an air conditioner outdoor unit and a control method for identifying a compressor. Background technique [0002] Generally, in a multi-split air conditioner, the same series of multi-split air conditioners has multiple outdoor units of different models, and the type and quantity of the inverter compressors of each type of outdoor unit are different. Each variable frequency compressor needs a variable frequency drive module to drive the operation of the compressor, wherein the drive module is divided into hardware and software parts. Between different variable frequency compressors, the electronic control hardware of the variable frequency drive may be the same, but the software of the driver is different. When the variable frequency compressor uses the wrong driver software or hardware, the variable frequency compressor may continue...
