[0042] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0043] In the description of the embodiments of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0044] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0045] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0046] The present invention provides a control method for a rapid cooling and heating mode, which is used to control an air conditioner. The controlled air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner, etc., without limitation herein.

[0047] like Figure 1 As shown, the control method of the rapid cooling and heating mode includes the following steps:

[0048] Step S110: Determine that the air conditioner is in the rapid cooling and heating mode, adjust the compressor to the initial frequency, and adjust the expansion valve to the initial opening.

[0049] After the air conditioner is turned on, if the user inputs a rapid cooling and heating mode, the air conditioner starts the rapid cooling and heating mode according to the rapid cooling and heating mode command. In this embodiment, the rapid cooling and heating mode includes: a rapid cooling mode and a rapid heating mode.

[0050] When the air conditioner is activated in rapid cooling or heating mode, it adjusts the compressor frequency and expansion valve opening. The compressor is adjusted to its initial frequency, and the expansion valve is simultaneously adjusted to its initial opening. The initial compressor frequency corresponds to the air conditioner's maximum oil return frequency; that is, when the compressor is at its initial frequency, the compressor's oil return rate is at its maximum at that frequency. The initial expansion valve opening corresponds to the air conditioner's minimum oil return opening, meaning the expansion valve initial opening is maintained at the valve opening that produces the lowest return oil level. This ensures the maximum oil return rate is maintained throughout the air conditioner's operation.

[0051] Specifically, when the compressor is running, the refrigerant in the compressor is quickly discharged and circulated in the piping system. During this circulation process, the lubricating oil is discharged from the compressor along with the refrigerant and enters the piping. Only when this discharged lubricating oil smoothly returns to the compressor (i.e., oil return) can the dynamic balance of the lubricating oil in the entire system be maintained. Otherwise, the compressor will be damaged due to oil shortage.

[0052] To address the above issues, when the air conditioner is activated in rapid cooling or heating mode, the frequency is rapidly adjusted to the initial frequency. After the compressor starts, the frequency is directly and rapidly increased to the maximum oil return frequency. To ensure rapid oil return during operation at the maximum oil return frequency, the expansion valve opening is simultaneously controlled and adjusted. The expansion valve opening is driven by a stepper motor, which reduces the expansion valve opening so that the initial expansion valve opening corresponds to the air conditioner's minimum oil return opening. For example, the expansion valve opening can be 500 steps when the air conditioner is off. The baseline opening is set based on the operating mode, corresponding to the outdoor temperature and compressor frequency; for example, the baseline opening can be 300 steps. That is, after the air conditioner starts normally, the expansion valve opening is first reduced from 500 steps to 300 steps. If the rapid cooling or heating mode is activated, it is further reduced from 300 steps to the minimum oil return opening. This allows the compressor and expansion valve to maintain the maximum oil return rate, allowing some discharged lubricating oil to quickly return to the compressor, maintaining the dynamic balance of lubricating oil throughout the system.

[0053] Step S120: Based on the exhaust temperature of the compressor, the operating frequency of the compressor is corrected on the basis of the initial frequency.

[0054] The increase in the operating frequency of the compressor directly affects the cooling and heating speed of the air conditioner. However, as the operating frequency of the compressor increases, the discharge speed of the lubricating oil also becomes faster and faster. When the discharge speed of the lubricating oil exceeds the maximum oil return speed of the oil return capillary, oil shortage is likely to occur.

[0055] To this end, after adjusting the compressor and expansion valve, in order to ensure the cooling and heating speed of the air conditioner, the air conditioner obtains the exhaust temperature of the compressor through a sensor, and corrects the operating frequency of the compressor based on the initial frequency based on the exhaust temperature, so that the exhaust temperature can be maintained within a certain range while ensuring oil return, thereby ensuring the cooling or heating speed of the air conditioner.

[0056] Step S130: Based on the exhaust gas temperature and the refrigerant pressure of the heat exchanger, the opening of the expansion valve is corrected on the basis of the initial opening.

[0057] While the operating frequency of the compressor is corrected on the basis of the initial frequency based on the exhaust temperature, the air conditioner continues to obtain the refrigerant pressure of the heat exchanger through the sensor.

[0058] Specifically, during cooling, the air conditioner obtains the refrigerant pressure in the indoor heat exchanger through a sensor. Based on the exhaust temperature and the refrigerant pressure in the indoor heat exchanger, the opening of the expansion valve is corrected based on the initial opening of the expansion valve. On the basis of ensuring that the refrigeration condition can return oil normally, the cooling speed of the air conditioner is ensured.

[0059] During heating, the air conditioner obtains the refrigerant pressure in the outdoor heat exchanger through a sensor. Based on the exhaust temperature and the refrigerant pressure in the outdoor heat exchanger, the opening of the expansion valve is corrected on the basis of the initial opening of the expansion valve. On the basis of ensuring that the heating condition can return oil normally, the heating speed of the air conditioner is ensured.

[0060] The control method for the rapid cooling and heating mode provided by the present invention first adjusts the compressor to an initial frequency for operation, adjusts the expansion valve to an initial opening for operation, uses the exhaust temperature of the compressor to correct the operating frequency of the compressor, and simultaneously uses the exhaust temperature and the refrigerant pressure of the heat exchanger to correct the opening of the expansion valve, so that the air conditioner can achieve the purpose of rapid cooling or heating on the basis of quickly completing oil return, thereby improving the user experience.

[0061] In one example, if Figure 2 As shown, step S120: based on the exhaust temperature of the compressor, the step of correcting the operating frequency of the compressor on the basis of the initial frequency includes:

[0062] Step S210: Determine whether the exhaust gas temperature reaches the first target exhaust gas temperature.

[0063] After the air conditioner obtains the exhaust temperature of the compressor through the sensor, it compares the exhaust temperature of the compressor with the first target exhaust temperature to determine whether the exhaust temperature reaches the first target exhaust temperature.

[0064] Step S220: when the exhaust gas temperature is lower than the first target exhaust gas temperature, increasing the operating frequency of the compressor based on the initial frequency.

[0065] Since the exhaust temperature is the temperature of the exhaust gas after the compressor works, it can be measured from the exhaust pipe with a thermometer. The exhaust temperature is proportional to the pressure ratio and the suction temperature. The greater the pressure ratio, the higher the suction temperature, and the higher the exhaust temperature. In the process of ensuring rapid cooling and heating of the air conditioner, it is necessary to ensure that the exhaust temperature is within a stable range. Therefore, a first target exhaust temperature is set. The first target exhaust temperature is generally lower than 150 degrees Celsius. Those skilled in the art can set the first target exhaust temperature to any reasonable value so that it meets more specific application scenarios. For example, the first target exhaust temperature can be set to the exhaust temperature corresponding to the highest cooling or heating efficiency.

[0066] After comparison, when it is determined that the detected exhaust temperature is lower than the first target exhaust temperature, that is, when the detected exhaust temperature is less than the first target exhaust temperature, it means that the exhaust temperature does not meet the design requirements and the exhaust temperature needs to be further increased, the operating frequency of the compressor is increased based on the initial frequency of the compressor.

[0067] Step S230: When the exhaust gas temperature is greater than or equal to the first target exhaust gas temperature, the operating frequency of the compressor is reduced or maintained based on the initial frequency.

[0068] When the exhaust temperature of the compressor is greater than or equal to the first target exhaust temperature, that is, when the detected exhaust temperature is ≥ the first target exhaust temperature, it means that the exhaust temperature has exceeded the design requirement and there is no need to further increase the exhaust temperature. In this case, the operating frequency of the compressor is reduced based on the initial frequency, or the operating frequency of the compressor is maintained to continue working.

[0069] After the adjustment, the exhaust temperature can be obtained again, and the operating frequency of the compressor can be further corrected using the first target exhaust temperature.

[0070] Based on the above embodiments, Figure 3 and Figure 4 As shown, step S130: based on the exhaust gas temperature and the refrigerant pressure of the heat exchanger, the step of correcting the opening of the expansion valve on the basis of the initial opening includes:

[0071] Step S310: Determine a first adjustment amount of the expansion valve opening based on the exhaust gas temperature.

[0072] After the air conditioner obtains the exhaust temperature through the sensor, it determines a first adjustment amount for the expansion valve opening based on the exhaust temperature. For example, when the exhaust temperature is low, the value of the first adjustment amount is reduced, and when the exhaust temperature is high, the value of the first adjustment amount is increased.

[0073] Specifically, before obtaining the exhaust temperature, a second target exhaust temperature is set. The second target exhaust temperature is generally lower than 150 degrees Celsius. Those skilled in the art can set the second target exhaust temperature to any reasonable value so that it meets more specific application scenarios. For example, the second target exhaust temperature can be set to the temperature corresponding to the highest cooling or heating efficiency.

[0074] After determining the second target exhaust temperature, the air conditioner obtains the exhaust temperature through a sensor, compares the detected exhaust temperature with the second target exhaust temperature, and determines whether the detected exhaust temperature reaches the second target exhaust temperature.

[0075] After comparison, if it is determined that the detected exhaust temperature is lower than the second target exhaust temperature, that is, the detected exhaust temperature is less than the second target exhaust temperature, it means that the exhaust temperature does not meet the design requirements and the exhaust temperature needs to be further increased, then the first adjustment amount is reduced to reduce the opening of the expansion valve.

[0076] When the exhaust temperature of the compressor is greater than or equal to the second target exhaust temperature, that is, when the detected exhaust temperature is ≥ the second target exhaust temperature, it means that the exhaust temperature has exceeded the design requirement and there is no need to further increase the exhaust temperature. In this case, the first adjustment amount is increased to increase the opening of the expansion valve.

[0077] Generally, when the detected exhaust temperature is less than the second target exhaust temperature, the first adjustment amount is a negative value to reduce the opening of the expansion valve. When the detected exhaust temperature is greater than or equal to the second target exhaust temperature, the first adjustment amount is a positive value to increase the opening of the expansion valve.

[0078] Step S320: Determine a second adjustment amount of the expansion valve opening based on the refrigerant pressure.

[0079] After the air conditioner obtains the refrigerant pressure through the sensor, it determines the second adjustment amount for the expansion valve opening based on the refrigerant pressure. For example, when the refrigerant pressure is low, the value of the second adjustment amount is increased, and when the refrigerant pressure is high, the value of the second adjustment amount is decreased.

[0080] Specifically, before obtaining the refrigerant pressure in the indoor heat exchanger or the outdoor heat exchanger, a target refrigerant pressure is set first. Those skilled in the art can set the target refrigerant pressure to any reasonable value so that it meets more specific application scenarios.

[0081] After determining the target refrigerant pressure, the air conditioner obtains the refrigerant pressure through the sensor and compares the detected refrigerant pressure with the target refrigerant pressure to determine whether the detected refrigerant pressure reaches the target refrigerant pressure.

[0082] After comparison, if it is determined that the detected refrigerant pressure is less than the target refrigerant pressure, that is, when the detected refrigerant pressure is less than the target refrigerant pressure, it means that the refrigerant pressure does not meet the design requirements and the pressure needs to be further increased, then the second adjustment amount is increased to increase the opening of the expansion valve.

[0083] When the refrigerant pressure of the compressor is greater than or equal to the target refrigerant pressure, that is, when the detected refrigerant pressure ≥ the target refrigerant pressure, it means that the refrigerant pressure has exceeded the design requirement and there is no need to further increase the pressure. In this case, the second adjustment amount is reduced to reduce the opening of the expansion valve.

[0084] Generally, when the detected refrigerant pressure is less than the target refrigerant pressure, the second adjustment amount is a positive value to increase the opening of the expansion valve. When the detected refrigerant pressure is greater than or equal to the target refrigerant pressure, the second adjustment amount is a negative value to decrease the opening of the expansion valve.

[0085] Step S330: Based on the initial opening, the opening of the expansion valve is determined based on the first adjustment amount and the second adjustment amount.

[0086] After the initial opening degree, the first adjustment amount, and the second adjustment amount are determined, the opening degree of the expansion valve is determined based on the initial opening degree, the first adjustment amount, and the second adjustment amount.

[0087] Specifically, the initial opening corresponds to the air conditioner's minimum oil return opening. The first adjustment amount is determined by the detected exhaust temperature, while the second adjustment amount is determined by the detected refrigerant pressure. The actual opening of the expansion valve is determined based on the weighted impact of the first and second adjustment amounts on the opening.

[0088] In other words, actual opening = initial opening + k1 * first adjustment + k2 * second adjustment. k1 is the weight of the first adjustment's effect on the opening, and k2 is the weight of the second adjustment's effect on the opening. By adjusting these weights, the optimal actual opening can be obtained, achieving rapid cooling or heating while ensuring the fastest possible oil return.

[0089] After the adjustment, the exhaust temperature and the refrigerant pressure can be obtained again, and the opening of the expansion valve can be further corrected using the second target exhaust temperature and the target refrigerant pressure.

[0090] In order to ensure normal oil return, after step S110 and before step S120, the process further includes: performing subsequent steps after a preset time after the compressor completes oil return.

[0091] For example, after the air conditioner detects that the compressor oil return is complete (after 3 minutes), that is, after the air conditioner determines the initial frequency and initial opening, it continues to operate at the initial frequency and initial opening for a period of time. After the oil return stabilizes, the air conditioner controls the compressor exhaust temperature and the refrigerant pressure of the heat exchanger to correct the compressor's operating frequency and the expansion valve opening. On the one hand, when the compressor has not completed oil return, the compressor operation is not stable. At this time, the error of using the compressor exhaust temperature and the refrigerant pressure of the heat exchanger to correct the air conditioner is large. On the other hand, in order to ensure rapid oil return, the compressor's operating frequency and the expansion valve opening are not corrected before the oil return is completed, so as to achieve the purpose of rapid cooling or heating.

[0092] The following describes a control system for a rapid cooling and heating mode provided by an embodiment of the present invention. The control system for the rapid cooling and heating mode described below and the control method described above can be referenced to each other.

[0093] like Figure 5 As shown, the control system of the rapid cooling and heating mode includes: an adjustment module 510 , a first correction module 520 and a second correction module 530 .

[0094] The adjustment module 510 is configured to adjust the compressor to an initial frequency and the expansion valve to an initial opening when the air conditioner is in rapid cooling mode. The initial frequency corresponds to the air conditioner's maximum oil return frequency, and the initial opening corresponds to the air conditioner's minimum oil return opening. A first correction module 520 is configured to correct the compressor's operating frequency based on the initial frequency based on the compressor's exhaust temperature. A second correction module 530 is configured to correct the expansion valve opening based on the initial opening based on the exhaust temperature and the refrigerant pressure of the heat exchanger.
