Problems solved by technology

Because the air conditioner often needs to adjust the system capacity and troubleshoot by fixing the opening of the electronic expansion valve in the R&D and after-sales stages, but the control of the air conditioner itself is more complicated and requires various input parameters for PID calculation and other processes, which is difficult to achieve Specific simulation of manual input, so it is necessary to use a driving device to control the opening of the electronic expansion valve
At present, the common driving devices are large in size and weight, and are inconvenient to carry; generally, they need an external power supply for independent power supply; they are expensive and have complex functions, making it difficult to control the cost during use
Moreover, the electronic expansion valves of major brands of commercial air-conditioning products currently on the market are driven by four-phase, four-phase or four-phase, eight-phase external interfaces with six-pin terminals. The driving device with a single driving type is often not very applicable. Difficult to adapt to market needs

Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, the air conditioner portable electronic expansion valve drive device of this embodiment includes an adaptive power supply module 1, the adaptive power supply module 1 is connected to the dual-mode electronic expansion valve drive module 2, and the dual-mode electronic expansion valve drive module 2 is connected to the opening display The module 3 and the opening demand setting module 4, the self-adaptive power supply module 1 includes the power terminal 5, the power terminal 5 is connected to the rectification circuit 6, and the rectification circuit 6 is connected to the filter circuit 7 and the voltage stabilizing circuit 8 in turn. The power terminal 5 is two kinds of common power input interfaces. The dual-mode electronic expansion valve drive module 2 includes an MCU micro-control unit 9, which receives instructions from the opening demand setting module 4, and the MCU micro-control unit 9 is connected to the dial selection s...

Embodiment 2

[0030] The same part of this embodiment and embodiment 1 is no longer repeated, and the difference is:

[0031] In the air conditioner portable electronic expansion valve drive device of this embodiment, in the dual-mode electronic expansion valve drive module 2, when the MCU micro-control unit 9 receives the opening demand setting module instruction, the four-phase eight-beat electronic expansion valve determined according to the dial selection switch 10 Expansion valve gear, call the corresponding software program (the software control process is as follows Figure 4 As shown), the stepping drive level is output through the general output I / O port, and then the driving capability is increased by the driver IC11, and finally output to the stepping motor of the electronic expansion valve to realize the opening action of the electronic expansion valve.

[0032] The operation process of this embodiment is as follows:

[0033] Insert the transformer output end of the indoor unit...

Description

technical field [0001] The invention relates to an electronic expansion valve driving device, in particular to a portable electronic expansion valve driving device used in commercial air conditioners, which belongs to the technical field of air conditioner production. Background technique [0002] In the production and maintenance process of commercial air conditioners, the electronic expansion valve is an important throttling device, which can realize the variable flow control of the refrigerant in the refrigeration system and is widely used. Because the air conditioner often needs to adjust the system capacity and troubleshoot by fixing the opening of the electronic expansion valve in the R&D and after-sales stages, but the control of the air conditioner itself is more complicated and requires various input parameters for PID calculation and other processes, which is difficult to achieve The specific simulation of manual input, so it is necessary to use the driving device ...
