Embodiment 1

[0064] Such as figure 2 As shown, the operation control method according to an embodiment of the present invention includes: Step 202: In response to the start-up operation command, adjust the opening degree of the throttling device to the first opening degree; Step 204: Detect the working condition of the air conditioner If the parameter satisfies the first adjustment condition, then adjust the opening degree of the throttling device to the second opening degree; Step 206: It is detected that the operating condition parameters of the air conditioner meet the second adjustment condition, then adjust the throttling according to the adjustment rule of the current operation mode The degree of opening of the device, wherein the second degree of opening is smaller than the first degree of opening.

[0065] In this embodiment, in step 202, when the start-up command is obtained, the opening degree of the throttling device 40 is firstly adjusted to the first opening degree, so as to ...

Embodiment 2

[0069] Such as image 3 As shown, the operation control method according to another embodiment of the present invention includes: step 302, in response to the start-up operation instruction, control the compressor to start with fs as the frequency of the compressor, and adjust the throttling device according to the preset adjustment rate The opening is adjusted to the first opening.

[0070] In this embodiment, when the start-up command is obtained, the opening degree of the throttling device 40 is adjusted to the first opening degree according to the preset adjustment rate, so that the throttling device 40 can be quickly adjusted to the first opening degree, which is convenient for the refrigerant to quickly Passing, thereby helping to increase the speed of cooling or heating during the start-up phase.

[0071] Step 304, the operating condition parameters include time operating condition parameters, and record the second duration of the throttling device at the first opening d...

Embodiment 3

[0076] Such as Figure 4 As shown, the operation control method according to an embodiment of the present invention includes: step 402, in response to the start-up operation instruction, control the compressor to start with fs as the frequency of the compressor, and adjust the opening of the throttling device according to the preset adjustment rate Adjust to the first opening degree.

[0077] Step 404, when the throttling device is at the first opening degree, respectively collect the room temperature, the tube temperature of the indoor heat exchanger, the tube temperature and the outdoor temperature of the outdoor heat exchanger.

[0078] When the relationship between the detected room temperature, the tube temperature of the indoor heat exchanger temperature, the tube temperature of the outdoor heat exchanger, and the outdoor temperature satisfies the switching condition, it is determined that the working condition parameters of the air conditioner meet the first adjustment ...

Abstract

The present invention provides an operation control method, an operation control device, an air conditioner, and a storage medium, wherein the operation control method is suitable for an air conditioner, and the air conditioner includes an indoor unit and an outdoor unit, and a designated flow between the indoor unit and the outdoor unit is connected. A throttling device is installed on the road, and the operation control method includes: adjusting the opening degree of the throttling device to the first opening degree in response to the start-up operation command; detecting that the operating condition parameters of the air conditioner meet the first adjustment condition, then throttling The opening degree of the device is adjusted to the second opening degree; it is detected that the working condition parameters of the air conditioner meet the second adjustment condition, and the opening degree of the throttling device is adjusted according to the adjustment rule of the current operation mode, wherein the second opening degree is smaller than the first opening. The technical solution of the invention is beneficial to increase the establishment speed of the system suction and exhaust pressure difference and heat exchange temperature difference during the start-up stage of the air conditioner, so as to achieve the purpose of rapid cooling or heating.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] In the prior art, the compressor starts at a lower frequency after starting up, and the opening of the throttling device is fixed a few minutes before starting, and the adjustment is started after the system pressure difference is established, but the low frequency start of the compressor is not conducive to rapid establishment The pressure difference and the fixed opening are not conducive to the rapid establishment of the suction and exhaust pressure difference and the heat transfer temperature difference, thus affecting the cooling and heating efficiency. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. ...
