Problems solved by technology

[0003] Since the electronic expansion valve is a high-precision processing part with a high surface smoothness, the contact between the valve needle and the valve seat surface is a rigid metal contact. The long-term occlusion will cause deformation, and due to diffusion, it will form adhesion on the contact surface. It is easy to damage the smoothness of the surface when it is separated again, which will affect the control accuracy of the electronic expansion valve
Due to the great randomness of the shut-off opening, taking the electronic expansion valve that can be cut off as an example, when it is shut down in the throttling state, or when it needs to be in the throttling state for a long time, there will be a risk of failure or reduced accuracy, which will affect the electronic expansion valve. Use reliability and control precision

Embodiment 1

[0064] Such as Figure 5 As shown, a method of operation control includes:

[0065] Step S502, in response to the shutdown command, adjust the opening of the throttling device 18 to zero flow opening or below, and control the air conditioner to enter the standby state;

[0066] If no start-up command is received and the operating condition parameters of the air conditioner meet the preset conditions, the opening of the throttling device 18 is adjusted to a preset opening, wherein the preset opening is greater than the zero flow opening.

[0067] Further, the operating condition parameters include time operating condition parameters and time operating condition parameters. If no start-up command is received and the operating condition parameters of the air conditioner meet the preset conditions, the opening degree of the throttling device 18 is adjusted to the preset opening degree , including:

[0068] Step S504, judging whether a power-on command is received;

[0069] If t...

Embodiment 2

[0093] Such as Figure 7 As shown, a method of operation control includes:

[0094] Step S702, in response to the shutdown command, adjust the opening of the throttling device 18 to zero flow opening or below, and control the air conditioner to enter the standby state;

[0095] If no start-up command is received and the operating condition parameters of the air conditioner meet the preset conditions, the opening of the throttling device 18 is adjusted to a preset opening, wherein the preset opening is greater than the zero flow opening.

[0096] Further, the operating condition parameters include time operating condition parameters and temperature operating condition parameters. If no start-up command is received and the operating condition parameters of the air conditioner meet the preset conditions, the opening of the throttling device 18 is adjusted to the preset opening degree , including:

[0097] Step S704, judging whether a power-on command is received;

Abstract

The invention provides an air conditioner and its operation control method, device and computer-readable storage medium. The operation control method includes: adjusting the opening of the throttling device to zero flow opening or zero flow opening in response to a shutdown command Below, and the air conditioner enters the standby state; if the start-up command is not received, and the working condition parameters of the air conditioner meet the preset conditions, adjust the opening of the throttling device to the preset opening, wherein the preset opening is greater than zero Flow opening. In the operation control method provided by the present invention, when the start-up command is not received, that is, when the air conditioner is still in the standby state, if the working condition parameters of the air conditioner meet the preset conditions, the opening of the throttling device is adjusted to be greater than the zero flow opening The preset opening degree of the throttle device can avoid the failure of the throttle device or the reduction of precision caused by the throttle device being in the closed throttle state for a long time, so that the long-term standby of the air conditioner can be realized without damaging the throttle device, and this application does not The structure of the air conditioner is changed, and the use cost is low.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to an air conditioner, its operation control method, device and computer-readable storage medium. Background technique [0002] The air conditioner has the characteristics of intermittent use. The opening of the standby between two uses is fixed at the opening of the shutdown or the standby opening with flow. The compressor, fan, throttling device, four-way valve, etc. are all powered off and do not work. [0003] Since the electronic expansion valve is a high-precision processing part with a high surface smoothness, the contact between the valve needle and the valve seat surface is a rigid metal contact, and deformation will occur after long-term occlusion, and due to diffusion, adhesion will be formed on the contact surface. When they are separated again, the smoothness of the surface is easily damaged, which affects the control accuracy of the electronic ex...
