Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its control method. Background Technology

[0002] A dual-column air conditioner has two parallel air columns with their air outlets facing each other. Each column contains a cross-flow fan and an indoor heat exchanger. The two indoor heat exchangers are connected in parallel, and the refrigerant flow through them is equal and fixed. Currently, when the indoor temperature is close to the user's set temperature, the air conditioner controls the temperature by reducing the operating frequency. However, the compressor operates at its minimum frequency, and the room temperature will still reach the user's set temperature. Once the set temperature is reached, the compressor stops working, i.e., the air conditioner shuts off. When the room temperature exceeds the set temperature, the air conditioner restarts. Therefore, existing air conditioners have a problem of frequent shutdowns when reaching the set temperature. This leads to large fluctuations in room temperature, high operating noise, and severely affects the lifespan of the compressor, thus greatly reducing the reliability and safety of the air conditioner and diminishing the user experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide an air conditioner and its control method that overcome or at least partially solve the above problems, aiming to solve the problem of frequent shutdown after reaching the temperature in existing dual-column air conditioners, so as to improve the user experience.

[0004] On one hand, the present invention provides a control method for an air conditioner, the air conditioner including at least two air outlets, each air outlet including an air outlet and an indoor heat exchanger; the air conditioner also includes a flow path control device configured to regulate the refrigerant flow rate through each of the indoor heat exchangers;

[0005] The control method includes: in response to the air conditioner meeting the preset shutdown conditions, shutting down the indoor heat exchanger corresponding to a portion of the air outlets, and controlling a portion of the air outlets to not blow air or to blow non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air.

[0006] Optionally, the control method further includes:

[0007] The indoor ambient temperature is obtained to obtain a first temperature;

[0008] When the air conditioner is operating in cooling mode, if the first temperature remains below the first preset temperature for a first preset time period, the compressor is controlled to stop; or

[0009] When the air conditioner is in heating mode, if the first temperature remains higher than the second preset temperature for a first preset time, the compressor is controlled to stop.

[0010] Optionally, the first preset temperature is lower than the set temperature of the air conditioner;

[0011] The second preset temperature is higher than the set temperature of the air conditioner.

[0012] Optionally, the control method further includes:

[0013] In response to the compressor operating at the lowest frequency and after a set time, the indoor ambient temperature is acquired to obtain a second temperature;

[0014] The air conditioner is judged to meet the preset shutdown conditions based on the second temperature.

[0015] Optionally, determining whether the air conditioner meets the preset shutdown conditions based on the second temperature includes:

[0016] When the air conditioner is in cooling mode, if the second temperature is lower than the set temperature of the air conditioner, then the air conditioner is determined to meet the preset shutdown conditions; or

[0017] When the air conditioner is in heating mode, if the second temperature is greater than the set temperature of the air conditioner, then the air conditioner is determined to meet the preset shutdown conditions.

[0018] Optionally, the control method further includes:

[0019] In response to the air conditioner being activated, the indoor ambient temperature is acquired to obtain a third temperature;

[0020] Determine whether the third temperature meets the preset conditions;

[0021] If so, control the compressor to operate at the lowest frequency.

[0022] Optionally, determining whether the third temperature meets the preset conditions includes:

[0023] When the air conditioner is in cooling mode, if the third temperature is lower than the third preset temperature, and the third preset temperature is higher than the air conditioner's set temperature, then the air conditioner is determined to meet the preset conditions; or

[0024] When the air conditioner is in heating mode, if the third temperature is greater than the fourth preset temperature and the fourth preset temperature is less than the set temperature of the air conditioner, then the air conditioner is determined to meet the preset conditions.

[0025] Optionally, the flow path control device includes multiple electronic expansion valves, with each indoor heat exchanger connected in series with one of the electronic expansion valves; or

[0026] The flow path control device includes multiple electronic shut-off valves, with each indoor heat exchanger connected in series with one of the electronic shut-off valves.

[0027] Optionally, there are two air outlets;

[0028] Both air outlets are vertically arranged; or

[0029] Both air outlets are horizontally positioned.

[0031] In the air conditioner control method of the present invention, the refrigerant flow rate of each indoor heat exchanger can be adjusted by a flow path control device, thereby adjusting the heat exchange capacity of each indoor heat exchanger. When the air conditioner meets the preset shutdown conditions, the heat exchanger corresponding to part of the air outlet is shut down, which can significantly reduce the cooling or heating capacity of the air conditioner, thereby effectively avoiding or delaying the phenomenon of shutdown upon reaching the set temperature. Therefore, the present invention can achieve the goal of air conditioner shutting down without stopping when reaching the set temperature, avoiding frequent start-stop of the compressor, and avoiding the problem of high noise caused by discontinuous sound emitted by the air conditioner. It also improves the service life of the compressor and the reliability and safety of the air conditioner, reduces indoor temperature fluctuations, avoids sudden changes in indoor temperature, and improves the user experience. In addition, the control method of the present invention has the beneficial effect of simple and easy-to-execute control program. Furthermore, the present invention solves the problem of homogeneous air supply function of the two air outlets in existing dual-column air conditioners, and can meet the differentiated needs of users for the cooling or heating capacity of the two air outlets, thereby satisfying the diverse air supply needs of users.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, and in conjunction with... Figure 2-6 The present invention provides a control method for an air conditioner. The air conditioner includes an indoor unit 10, the indoor unit 10 including at least two air outlets, each air outlet including an air outlet and an indoor heat exchanger 11; the air conditioner also includes a flow path control device configured to regulate the refrigerant flow rate through each of the indoor heat exchangers.

[0044] like Figure 1 As shown, the control method for the air conditioner includes the following steps: in response to the air conditioner meeting a preset shutdown condition, the indoor heat exchanger corresponding to a portion of the air outlets is shut off, and the air outlets are controlled to stop blowing air, while the remaining air outlets remain unchanged and blow out heat exchange air. In some alternative embodiments, the control method for the air conditioner includes the following steps: in response to the air conditioner meeting a preset shutdown condition, the indoor heat exchanger corresponding to a portion of the air outlets is shut off, and the air outlets are controlled to blow out non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air.

[0045] Specifically, the indoor unit can have two, three, or four air outlets, the number of which can be designed according to the indoor unit's shape or main function. The indoor heat exchangers of each air outlet are connected in parallel. For example, with two air outlets, when the air conditioner meets the preset shutdown conditions, the indoor heat exchanger corresponding to one air outlet is shut down, and that air outlet is controlled to not blow air or blow non-heat exchange air, while the other air outlet remains unchanged, blowing out heat exchange air.

[0046] In this embodiment, the refrigerant flow rate of each indoor heat exchanger can be adjusted by the flow path control device, thereby adjusting the heat exchange capacity of each indoor heat exchanger and thus the cooling or heating capacity of the air conditioner. When the air conditioner meets the preset shutdown conditions, the heat exchanger corresponding to part of the air outlet is shut down, which can significantly reduce the cooling or heating capacity of the air conditioner, thereby effectively avoiding or delaying the phenomenon of shutdown upon reaching the set temperature. Therefore, the present invention can achieve the goal of the air conditioner not shutting down after reaching the set temperature, avoiding frequent start-stop of the compressor, and avoiding the problem of high noise caused by the discontinuous sound emitted by the air conditioner. It also improves the service life of the compressor and the reliability and safety of the air conditioner, reduces indoor temperature fluctuations, avoids sudden changes in indoor temperature, and improves the user experience. In addition, the control method of the present invention has the beneficial effect of simple and easy-to-execute control program. Furthermore, the present invention solves the problem of homogeneous air supply function of the two air outlets in existing dual-column air conditioners, and can meet the differentiated needs of users for the cooling or heating capacity of the two air outlets, thereby satisfying the diverse air supply needs of users.

[0047] In some optional embodiments of the present invention, the various air outlets are separate structures. In some alternative embodiments, the various air outlets are a single integrated structure.

[0048] In some alternative embodiments of the invention, the air outlets are distributed laterally; correspondingly, the air vents are distributed laterally, and the indoor heat exchangers 11 are distributed laterally. In some alternative embodiments, the air outlets are distributed vertically; correspondingly, the air vents are distributed vertically, and the indoor heat exchangers 11 are distributed vertically. The distribution of the air outlets can be designed according to the indoor unit's shape or main function.

[0049] like Figure 2 As shown, in some optional embodiments of the present invention, the control method includes the following steps: in response to the air conditioner meeting a preset shutdown condition, the indoor heat exchanger corresponding to a portion of the air outlet is shut off, and the portion of the air outlet is controlled to not blow air or to blow non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air; the indoor ambient temperature is obtained to obtain a first temperature; when the air conditioner is running in cooling mode, if the first temperature is continuously lower than the first preset temperature within a first preset time, the compressor is controlled to shut down.

[0050] Specifically, when the air conditioner is running in cooling mode, if the first temperature remains lower than the first preset temperature for a first preset time, it indicates that the operation of closing the heat exchanger corresponding to part of the air outlet has failed to regulate the indoor temperature or the regulation effect is poor. At this time, controlling the compressor to stop can reduce the impact on the user's experience due to the indoor temperature being lower than the air conditioner's set temperature.

[0051] Furthermore, in some optional embodiments of the present invention, the first preset temperature is less than the set temperature of the air conditioner. For example, the first preset temperature = the set temperature of the air conditioner - 1°C, or the first preset temperature = the set temperature of the air conditioner - 2°C.

[0052] like Figure 2 As shown, in some optional embodiments of the present invention, the control method includes the following steps: in response to the air conditioner meeting a preset shutdown condition, the indoor heat exchanger corresponding to a portion of the air outlet is shut off, and the portion of the air outlet is controlled to not blow air or to blow non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air; the indoor ambient temperature is obtained to obtain a first temperature; when the air conditioner is in heating mode, if the first temperature is continuously greater than a second preset temperature within a first preset time, the compressor is controlled to shut down.

[0053] Specifically, when the air conditioner is in heating mode, if the first temperature is consistently higher than the second preset temperature within a first preset time, it indicates that the operation of shutting down the heat exchanger corresponding to part of the air outlet has failed to regulate the indoor temperature or the regulation effect is poor. At this time, controlling the compressor to stop can reduce the impact of the indoor temperature being higher than the air conditioner's set temperature on the user's experience.

[0054] Furthermore, in some optional embodiments of the present invention, the second preset temperature is greater than the set temperature of the air conditioner. For example, the second preset temperature = the set temperature of the air conditioner + 1°C, or the second preset temperature = the set temperature of the air conditioner + 2°C.

[0055] Furthermore, in some optional embodiments of the present invention, the first preset time is 5 to 15 minutes (e.g., 5 minutes, 6 minutes, 8 minutes, 10 minutes, 12 minutes, or 10 minutes). Preferably, the first preset time is 10 minutes.

[0056] like Figure 3 As shown, in some optional embodiments of the present invention, the control method further includes the following steps: in response to the compressor operating at the lowest frequency and after a set time, acquiring the indoor ambient temperature to obtain a second temperature; and determining whether the air conditioner meets the preset shutdown conditions based on the second temperature.

[0057] Specifically, the set time is 5 to 10 minutes (e.g., 5 minutes, 6 minutes, 8 minutes, or 10 minutes). After the compressor runs at the lowest frequency for the set time, the indoor ambient temperature is acquired to obtain a second temperature; based on the second temperature, it is determined whether the air conditioner meets the preset shutdown conditions.

[0058] like Figure 3 As shown, in some optional embodiments of the present invention, determining whether the air conditioner meets the preset shutdown conditions based on the second temperature includes: when the air conditioner is running in cooling mode, if the second temperature is less than the set temperature of the air conditioner, then it is determined that the air conditioner meets the preset shutdown conditions.

[0059] like Figure 3 As shown, in some optional embodiments of the present invention, determining whether the air conditioner meets the preset shutdown conditions based on the second temperature includes: when the air conditioner is in heating mode, if the second temperature is greater than the set temperature of the air conditioner, then it is determined that the air conditioner meets the preset shutdown conditions.

[0060] The control method further includes the following steps: in response to the start of the air conditioner, acquiring the indoor ambient temperature to obtain a third temperature; determining whether the third temperature meets a preset condition; if so, controlling the compressor to run at the lowest frequency.

[0061] Furthermore, if the third temperature does not meet the preset conditions, the compressor is controlled to run at the original frequency, and the air conditioner is controlled to run in the original mode.

[0062] In some optional embodiments of the present invention, determining whether the third temperature meets the preset conditions includes: when the air conditioner is running in cooling mode, if the third temperature is less than the third preset temperature and the third preset temperature is greater than the set temperature of the air conditioner, then it is determined that the air conditioner meets the preset conditions.

[0063] Specifically, when the air conditioner is in cooling mode, if the set temperature < the third temperature < the third preset temperature, then the air conditioner is determined to meet the preset conditions. For example: the third preset temperature = the set temperature of the air conditioner + 1℃; or, the third preset temperature = the set temperature of the air conditioner + 2℃. In this embodiment, during cooling operation, before the indoor ambient temperature reaches the set temperature, controlling the compressor to operate at the lowest frequency can reduce the cooling capacity of the air conditioner, thereby delaying or preventing the indoor temperature from reaching the set temperature.

[0064] In some optional embodiments of the present invention, determining whether the third temperature meets the preset conditions includes: when the air conditioner is in heating mode, if the third temperature is greater than the fourth preset temperature and the fourth preset temperature is less than the set temperature of the air conditioner, then it is determined that the air conditioner meets the preset conditions.

[0065] Specifically, when the air conditioner is in cooling mode, if the fourth preset temperature < the third temperature < the set temperature, then the air conditioner is determined to meet the preset conditions. For example: the fourth preset temperature = the set temperature of the air conditioner - 1℃; or, the fourth preset temperature = the set temperature of the air conditioner - 2℃. In this embodiment, during heating mode, before the indoor ambient temperature reaches the set temperature, controlling the compressor to operate at the lowest frequency can reduce the heating capacity of the air conditioner, thereby delaying or preventing the indoor temperature from reaching the set temperature.

[0066] like Figure 4 As shown, in some optional embodiments of the present invention, when the air conditioner is in cooling operation, the control method of the air conditioner includes the following steps:

[0067] Step S11: In response to the air conditioner starting up, the indoor ambient temperature is obtained to obtain the third temperature.

[0068] Step S12: Determine whether the third temperature is less than the third preset temperature.

[0069] Step S13: If yes, control the compressor to operate at the lowest frequency.

[0070] Step S14: Obtain the indoor ambient temperature to obtain the second temperature.

[0071] Step S15: Determine whether the second temperature is lower than the set temperature of the air conditioner.

[0072] Step S16: If yes, shut down the indoor heat exchanger corresponding to part of the air outlet and control part of the air outlet to not blow air or blow non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air.

[0073] Step S17: Determine whether the first temperature remains below the first preset temperature within the first preset time period.

[0074] Step S18: If yes, control the compressor to stop; if no, return to step S16.

[0075] In this embodiment, the third preset temperature = set temperature + 1℃; the first preset time is 10 min; the first preset temperature = set temperature - 1℃.

[0076] like Figure 5 As shown, in some optional embodiments of the present invention, when the air conditioner is in heating mode, the control method of the air conditioner includes the following steps:

[0077] Step S21: In response to the air conditioner starting up, the indoor ambient temperature is obtained to obtain the third temperature.

[0078] Step S22: Determine that the third temperature is greater than the fourth preset temperature.

[0079] Step S23: If yes, control the compressor to operate at the lowest frequency.

[0080] Step S24: Obtain the indoor ambient temperature to obtain the second temperature.

[0081] Step S25: Determine whether the second temperature is greater than the set temperature of the air conditioner.

[0082] Step S26: If yes, shut down the indoor heat exchanger corresponding to part of the air outlet and control part of the air outlet to not blow air or blow non-heat exchange air, while the remaining air outlets remain unchanged and blow out heat exchange air.

[0083] Step S17: Determine whether the first temperature is continuously greater than the second preset temperature within the first preset time period.

[0084] Step S18: If yes, control the compressor to stop; if no, return to step S16.

[0085] In this embodiment, the fourth preset temperature = set temperature - 1℃; the first preset time is 10 min; and the second preset temperature = set temperature + 1℃.

[0086] like Figure 6As shown, in some alternative embodiments of the present invention, the flow path control device includes a plurality of electronic expansion valves, with each indoor heat exchanger connected in series with one of the electronic expansion valves.

[0087] Specifically, the electronic expansion valve 12 is configured to regulate the refrigerant flow through the indoor heat exchanger 11 by controlling its opening degree. The electronic expansion valve 12 controls the refrigerant flow through the indoor heat exchanger 11, and can move from closed to fully open in units of one coil-driven step. Each electronic expansion valve 12 can be controlled independently.

[0088] In some alternative embodiments of the invention, the flow path control device includes a plurality of electronic shut-off valves, with each indoor heat exchanger connected in series with one of the electronic shut-off valves.

[0089] Specifically, the electronic shut-off valves are configured to control the on / off state of the indoor heat exchanger 11. Each electronic shut-off valve can be controlled independently.

[0090] In some alternative embodiments of the present invention, the indoor unit includes two air outlets. Both air outlets are vertically arranged.

[0091] In some alternative embodiments of the present invention, the indoor unit includes two air outlets. Both air outlets are arranged horizontally.

[0092] The present invention also provides an air conditioner, the air conditioner including a control device, the control device including a memory and a processor, the memory storing a control program, the control program being executed by the processor to implement the control method of the air conditioner described in any of the above embodiments.

[0093] like Figure 6 As shown, in some optional embodiments of the present invention, the air conditioner includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 includes two air outlets, each including an air outlet, an indoor fan 13, and an indoor heat exchanger 11. The outdoor unit includes a compressor 23, an outdoor heat exchanger 21, and a four-way valve 22. The two indoor heat exchangers 11 are connected in parallel, and are respectively designated as a first indoor heat exchanger and a second indoor heat exchanger. The flow path control device includes two electronic expansion valves 12, each connected in series with its corresponding indoor heat exchanger 11. The electronic expansion valves 12, connected in series with the indoor heat exchangers 11, control the refrigerant flow rate in the indoor heat exchangers, ensuring stable and reliable operation. In some alternative embodiments, the flow path control device includes multiple electronic shut-off valves, with each indoor heat exchanger connected in series with an electronic shut-off valve.

[0094] In some alternative embodiments of the present invention, the indoor unit includes two air outlets. Both air outlets are vertically arranged.

[0095] In some alternative embodiments of the present invention, the indoor unit includes two air outlets. Both air outlets are arranged horizontally.

[0096] Furthermore, when the two air outlets are vertically arranged, they are symmetrically positioned about a vertically extending reference plane. When the two air outlets are horizontally arranged, they are symmetrically positioned about a horizontally extending reference plane. This symmetrical arrangement of the air outlets gives the air conditioner a stable and aesthetically pleasing design, which aligns with the aesthetic preferences of Chinese consumers.

[0097] Furthermore, the two air outlets are spaced apart to create an airflow gap between them. When the two air outlets blow air forward, the negative pressure drives the air in the airflow gap to flow forward, thus mixing this air with the air blown out by the two air outlets. During cooling, this lowers the air temperature and prevents the airflow from being too "hard," producing a "soft" airflow effect.

[0098] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
