Description

[Technical Field]

[0001] The present disclosure relates to the field of air conditioning technology, and in particular to a control method for an integrated air conditioner, a control device, an integrated air conditioner, a storage medium, and a computer program. [Background technology]

[0002] Air conditioners can be classified into separate and integrated air conditioners. Separate air conditioners have separate indoor and outdoor units, and the internal and external fan blades are driven by separate motors. The internal and external motors can be controlled to operate independently during defrosting. The evaporator and condenser of the separate air conditioner are installed indoors and outdoors, respectively. Integrated air conditioners use a single motor to control the internal and external fan blades, and the evaporator and condenser are both installed in the air conditioner body. Whether separate or integrated, frost forms on the condenser after a certain period of use in heating mode, and defrosting is required to prevent a decrease in efficiency. However, once defrosting is complete or in heating mode, the temperature of the indoor heat exchanger is low, causing the air conditioner to blow cool air, which can affect the user experience.

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Reference will now be made in detail to the embodiments illustrated in the accompanying drawings. In the drawings described below, the same numerals in different drawings refer to the same or similar elements unless otherwise specified. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects related to the present disclosure, as set forth in the appended claims.

[0028] The following embodiments of some embodiments of the present disclosure are not intended to represent all embodiments consistent with the present disclosure, but rather are merely illustrative of apparatus and methods consistent with certain aspects related to the present disclosure, as set forth in the appended claims.

[0029] It should be noted that all operations to acquire signals, information or data in this disclosure are in compliance with the relevant data protection laws and policies of the country in which the corresponding device is located and are performed with authorization granted by the owner of the corresponding device.

[0030] To prevent an all-in-one air conditioner from blowing cold air in heating mode and affecting the user's experience, the present disclosure provides a control method, a control device, an all-in-one air conditioner, a storage medium, and a computer program for an all-in-one air conditioner, which increases the opening of the first damper from a third target opening to the first target opening when the compressor's operating period in heating mode reaches a first preset period and / or the evaporator pipe temperature is higher than the first preset temperature, preventing the all-in-one air conditioner from blowing cold air and affecting the user's experience when the evaporator pipe temperature is low or the compressor's operating period in heating mode is short due to the first damper opening being too large.

[0031] In the present disclosure, the air conditioner control method can be applied to an integrated air conditioner, such as a processor or controller in the integrated air conditioner, where the integrated air conditioner can be a cabinet air conditioner or a mobile air conditioner.

[0032] First, the structure of the integrated air conditioner will be explained.

[0033] The integrated air conditioner includes a fan motor, a first fan blade, a second fan blade, a first damper, a second damper, an evaporator, and a condenser. The condenser and the corresponding second damper are located on the lower side of the air conditioner case, and the evaporator and the corresponding first damper are located on the upper side of the air conditioner case. The second damper corresponding to the condenser refers to the condenser-side damper, and the first damper corresponding to the evaporator refers to the evaporator-side damper. The fan motor controls the first and second fan blades, respectively. For example, the fan motor includes two shafts connected to the first and second fan blades, respectively. The first fan blade is the evaporator-side fan blade, and the second fan blade is the condenser-side fan blade. The first and second fan blades may include, but are not limited to, centrifugal fan blades.

[0034] For example, Figure 1 is a left side view of an integrated air conditioner according to an exemplary embodiment. As shown in Figure 1, 1 denotes the case of the integrated air conditioner, 2 denotes a first damper, 3 denotes a first damper motor used to control the position of the first damper, 4 denotes a connecting rod that drives the first damper so that the first damper is opened and closed, 5 denotes an evaporator, and 11 denotes a first fan blade.

[0035] 2 is a right side view of an integrated air conditioner according to an exemplary embodiment. As shown in FIG. 2, 1 denotes a case of the integrated air conditioner, 6 denotes a condenser, 7 denotes a second damper, 9 denotes a second damper motor used to control the position of the second damper, 8 denotes a connecting rod that drives the second damper to open and close the second damper motor, and 10 denotes a second fan blade.

[0036] The integrated air conditioner may also include a compressor, an expansion valve, and a four-way valve, and such devices are not shown in FIGS.

[0037] 3 illustrates a flowchart of a method for controlling an integrated air conditioner including a compressor, an evaporator, and a first damper corresponding to the evaporator according to an exemplary embodiment. As shown in FIG. 3, the method may include the following steps:

[0038] In step S31, if the integrated air conditioner is operating in heating mode, the evaporator pipe temperature and / or the duration that the compressor is operating in heating mode is obtained.

[0039] In step S32, if the period during which the compressor is operating in the heating mode reaches a first preset period and / or the evaporator pipe temperature is higher than the first preset temperature, the opening degree of the first damper is increased from the third target opening degree to the first target opening degree.

[0040] In the present disclosure, the evaporator pipe temperature and / or the duration of the compressor operating in heating mode affect the air discharge temperature of the integrated air conditioner, and the opening degree of the first damper affects the air discharge volume of the integrated air conditioner. Therefore, in the present disclosure, the opening degree of the first damper can be adjusted depending on the evaporator pipe temperature and / or the duration of the compressor operating in heating mode.

[0041] When the evaporator pipe temperature is low or the compressor is operating in heating mode for a short period of time, the air discharge temperature of the integrated air conditioner will be low. If the opening of the first damper is large at this time, the air discharge volume will be large, and a large amount of cold air will flow into the integrated air conditioner environment, seriously affecting the user's experience. Therefore, in the present disclosure, when the compressor is operating in heating mode for a first preset period and / or the evaporator pipe temperature is higher than the first preset temperature, the opening of the first damper is increased from the third target opening to the first target opening. The third target opening may be the opening of the first damper at the start of heating mode or the completion of defrosting.

[0042] In this embodiment, adjusting the damper opening refers to adjusting the damper opening position, where different damper opening positions correspond to different air discharge amounts. For example, the damper opening positions can be pre-classified. For example, as shown in FIG. 4 , the damper opening positions are classified from position 0 to position 10. When the damper opening position is position 0, the damper is fully closed, with the air discharge amount being minimal and close to zero. When the damper opening position is position 10, the damper is fully open, with the air discharge amount being the largest. The damper opening position shown in FIG. 4 is position 0. In this embodiment, the damper opening position can be adjusted between position 0 and position 10, i.e., the damper opening can be controlled to any of the openings corresponding to position 0 and position 10. Each corresponding damper motor can be used to control the damper opening. For example, the third target opening may be the opening corresponding to position 0.

[0043] For example, if the first preset temperature is 35°C and the first preset period is 120 seconds, that is, if the period during which the compressor operates in heating mode reaches 120 seconds and / or the evaporator pipe temperature when the integrated air conditioner operates in heating mode is higher than 35°C, the opening degree of the first damper is increased from the third target opening degree to the first target opening degree. The first target opening degree may be any of the opening degrees corresponding to positions 1 to 9. For example, the first target opening degree may be the opening degree corresponding to position 3.

[0044] By using the above technical solution, when the evaporator pipe temperature is low, the opening degree of the first damper is controlled to be small to prevent cold air from flowing into the environment where the integrated air conditioner is located, and when the period during which the compressor is operating in heating mode reaches the first preset period and / or the evaporator pipe temperature is higher than the first preset temperature, the opening degree of the first damper is increased from the third target opening degree to the first target opening degree. In this way, by increasing the opening degree of the first damper, the heat from the evaporator can be effectively flowed into the environment, improving heating efficiency and achieving the purpose of heating and preventing cold air.

[0045] In one embodiment, if the period of operation in heating mode is long and / or the evaporator pipe temperature increases, the opening of the first damper can be further increased to further improve heating efficiency and heating and cold air prevention efficiency.

[0046] In this embodiment, the method may further include:

[0047] After the opening of the first damper is increased to the first target opening, the duration during which the opening of the first damper is at the first target opening is measured.

[0048] The opening degree of the first damper is increased from the first target opening degree to the second target opening degree depending on at least the duration for which the opening degree of the first damper is at the first target opening degree and / or the evaporator pipe temperature.

[0049] For example, it is determined whether a preset condition is satisfied according to the duration during which the opening degree of the first damper is at the first target opening degree and / or the evaporator pipe temperature, and if the preset condition is satisfied, the opening degree of the first damper is increased from the first target opening degree to the second target opening degree, where the preset conditions include the evaporator pipe temperature being higher than the second preset temperature, the duration during which the opening degree of the first damper is at the first target opening degree reaching the second preset period, the evaporator pipe temperature being higher than a third preset temperature, and the duration during which the opening degree of the first damper is at the first target opening degree reaching a third preset period that is longer than the second preset period.

[0050] For example, the second preset temperature is 40°C, the second preset period is 30 seconds, the third preset temperature is 42°C, and the third preset period is 300 seconds, i.e., when the evaporator pipe temperature is higher than 40°C and the duration during which the first damper is at the opening corresponding to position 3 is 30 seconds, and / or when the evaporator pipe temperature is higher than 42°C when the integrated air conditioner is operating in heating mode, and / or when the first damper is at the opening corresponding to position 3 for the duration of 300 seconds, the opening of the first damper is adjusted from the opening corresponding to position 3 to the opening corresponding to position 10, i.e., the first damper is controlled to be fully open.

[0051] By using the above technical solution, the opening degree of the first damper can be further increased, and the heating efficiency and the heating and cold wind prevention efficiency can be further improved.

[0052] When the integrated air conditioner is operating in heating mode, the second damper is maintained at a second target opening. For example, the second damper corresponding to the condenser is controlled to be maintained at the opening corresponding to position 10.

[0053] By using the above technical solution, when the integrated air conditioner is operating in heating mode, the opening degree of the second damper can be controlled to maintain the first target opening degree, which, on the one hand, can increase the condenser temperature and reduce the possibility of frosting on the condenser, and, on the other hand, can increase the heating speed of the evaporator pipe and further improve the heating efficiency.

[0054] In one embodiment, the integrated air conditioner further includes a fan blade motor, and when the integrated air conditioner is operating in a heating mode, the fan blade motor is controlled to operate at a first rotational speed, and the rotational speed of the fan blade motor can be increased after the opening degree of the first damper is increased to a first target opening degree.

[0055] In this embodiment, when the integrated air conditioner is operating in a heating mode, the fan blade motor is first controlled to operate at a first rotational speed, which may be a low airflow level rotational speed and may range from 450 RPM to 600 RPM. After that, the opening of the first damper is increased to the first target opening, and the rotational speed of the fan blade motor can also be increased to further improve heating efficiency.

[0056] A complete embodiment is described below to allow those skilled in the art to better understand the control method for an integrated air conditioner provided in this disclosure.

[0057] In the present disclosure, the method further includes determining whether the integrated air conditioner satisfies a preset defrosting condition, and in response to determining that the integrated air conditioner satisfies the preset defrosting condition, switching the operation mode of the integrated air conditioner to a cooling mode, so that the condenser can be defrosted when the integrated air conditioner is operating in the cooling mode.

[0058] The condenser is defrosted when condensation or frost forms on the surface of the condenser. For example, the integrated air conditioner is deemed to satisfy the preset defrosting condition when at least one of the following conditions is met: the integrated air conditioner has been operating in heating mode for a preset period of time, the difference between the evaporator pipe temperature and the integrated air conditioner's ambient temperature is within a preset range, the integrated air conditioner's compressor has been operating for a specific period of time, or the evaporator pipe temperature has reached a temperature threshold.

[0059] When the integrated air conditioner is operating in cooling mode, the condenser can be defrosted by controlling the refrigerant circulation through the operation of the compressor and / or by supplying heat to the condenser through the ambient temperature of the integrated air conditioner to increase the temperature on the condenser side.

[0060] Using the above technical solution, if the all-in-one air conditioner meets the preset defrosting conditions, the operating mode of the all-in-one air conditioner will be switched to cooling mode to defrost the condenser. In this way, a method for defrosting the condenser in cooling mode is proposed, which is not limited to defrosting in heating mode, thereby improving the flexibility of defrosting and improving the user experience.

[0061] Condenser defrosting can include a defrost preparatory stage and a defrost stage. The defrost preparatory stage refers to a stage in which the operating mode of the integrated air conditioner is switched to cooling mode. In this disclosure, the application scenario of the control method for the integrated air conditioner may be any operating mode in which the integrated air conditioner can initially induce condenser frosting.

[0062] As mentioned above, in general, when an air conditioner operates in heating mode, frost will form on the condenser after a certain period of use. Therefore, in one embodiment, an application scenario for the control method of the integrated air conditioner provided by the present disclosure is when the integrated air conditioner is initially in heating mode. For example, in response to determining that the integrated air conditioner satisfies a preset defrosting condition, the operating mode of the integrated air conditioner is switched from heating mode to cooling mode.

[0063] In one embodiment, the integrated air conditioner may further include a four-way valve, and switching the operation mode of the integrated air conditioner to the cooling mode in response to determining that the integrated air conditioner satisfies the preset defrost condition may include controlling the compressor to stop operating and the four-way valve to power off in response to determining that the integrated air conditioner satisfies the preset defrost condition, and when the period during which the compressor is stopped reaches a fourth preset period and the four-way valve reaches a power-off state, controlling the operation of the compressor to switch the operation mode of the integrated air conditioner to the cooling mode.

[0064] When the integrated air conditioner switches between cooling mode and heating mode, the four-way valve must change direction, and the four-way valve must change direction when the heat exchange system is in pressure equilibrium. Therefore, in this embodiment, when it is determined that the integrated air conditioner meets the preset defrosting condition, the compressor stops operating and the heat exchange system is maintained in pressure equilibrium.

[0065] The compressor stops operating during a fourth preset period to allow the four-way valve to complete the power-off or direction switching operation within the first preset period. For example, the fourth preset period can be 50 seconds.

[0066] In addition, in a possible manner of this embodiment, when it is determined that the integrated air conditioner satisfies the preset defrosting condition, the four-way valve can be directly controlled to power off. However, since the power-off of the four-way valve and the stop of the compressor are controlled simultaneously, there is a possibility that the four-way valve may be controlled to power off before the heat exchange system has reached a pressure equilibrium state, which may cause a problem that the four-way valve cannot successfully switch direction.

[0067] To ensure successful switching of the four-way valve when the heat exchange system is in a pressure equilibrium state, in another possible method of this embodiment, the four-way valve is controlled to be powered off after the compressor is stopped for a certain period of time. For example, controlling the four-way valve to be powered off in response to the integrated air conditioner satisfying the preset defrost condition may be controlling the four-way valve to be powered off after a fifth preset period that is shorter than the fourth preset period in response to the integrated air conditioner satisfying the preset defrost condition.

[0068] For example, the fifth preset period is 40 seconds and the fourth preset period is 50 seconds, and if it is determined that the integrated air conditioner meets the preset defrosting conditions, the compressor is controlled to stop operating, and after a delay of 40 seconds, the four-way valve is controlled to be powered off, and then when the period during which the compressor has stopped operating reaches 50 seconds and the four-way valve is in the power-off state, the compressor is started, thereby switching the operating mode of the integrated air conditioner from the heating mode to the refrigeration mode.

[0069] The integrated air conditioner further includes an expansion valve, and switching the operating mode of the integrated air conditioner to the cooling mode in response to determining that the integrated air conditioner satisfies the preset defrosting condition further includes controlling the expansion valve to operate at a preset maximum valve opening in response to determining that the integrated air conditioner satisfies the preset defrosting condition.

[0070] In order to ensure that the heat exchange system is in a pressure-balanced state during the defrost preparation stage, the expansion valve can be controlled to operate at a preset maximum valve opening, for example, the maximum valve opening is 480, at which time the expansion valve operates at the maximum valve opening to further balance the pressure in the heat exchange system. Also, after entering the defrost stage, if the integrated air conditioner is operating in cooling mode, the expansion valve can be controlled to operate at a first preset valve opening that is smaller than the maximum valve opening.

[0071] In this embodiment, when the operating mode of the integrated air conditioner is switched to cooling mode, there is no need to maintain pressure balance in the heat exchange system, and the expansion valve is controlled to operate at a first preset valve opening to achieve the throttle setting pressure difference and supply heat to the condenser, where the first preset valve opening is smaller than the maximum valve opening, for example, the value range of the first preset valve opening is [100, 400].

[0072] Also, during the pre-defrost stage, the fan blade motor can be controlled to operate at a minimum rotation speed to store heat and provide more heat for the subsequent defrost. For example, the minimum rotation speed ranges from 450 RPM to 600 RPM.

[0073] After the defrost preparation stage is completed, the operation mode of the integrated air conditioner is switched to cooling mode. Thereafter, the condenser is defrosted when the integrated air conditioner operates in cooling mode.

[0074] In the present disclosure, when the integrated air conditioner operates in a cooling mode, defrosting of the condenser is mainly performed by using the operation of the compressor and / or the ambient temperature of the integrated air conditioner. Therefore, in one embodiment, in order to improve defrosting efficiency, the method includes: When the integrated air conditioner is operating in a cooling mode, controlling the compressor to operate at a preset defrost frequency; When the integrated air conditioner is operating in a cooling mode, controlling the opening degree of the first damper so as to be maintained at a third target opening degree; When the integrated air conditioner is operating in cooling mode, the opening degree of the second damper is controlled to maintain the second target opening degree, and the first target opening degree is greater than the third target opening degree.

[0075] For example, in the defrosting stage, the compressor is controlled to operate at a preset defrosting frequency, where the preset defrosting frequency may be a pre-corrected frequency with high defrosting efficiency, for example, the preset defrosting frequency may be any value between 50 Hz and 90 Hz.

[0076] When defrosting the condenser using the ambient temperature, the greater the opening of the second damper, the higher the efficiency of heat exchange between the condenser and the ambient temperature. Therefore, the opening of the second damper can be adjusted to increase the defrosting efficiency; for example, the opening of the second damper is controlled to the maximum opening.

[0077] In addition, when defrosting the condenser, the first damper can also be closed to prevent heat loss from the evaporator, i.e., the above-mentioned third target opening degree can basically be an opening degree corresponding to position 0.

[0078] By using the above technical solution, in the defrosting stage, at least one of the following can be performed: controlling the compressor to operate at a preset defrosting frequency; maintaining the opening degree of the first damper at the third target opening degree; and maintaining the opening degree of the second damper at the second target opening degree. In this way, it is possible to improve heat exchange efficiency and defrosting efficiency.

[0079] When the integrated air conditioner is operating in heating mode, the first damper corresponding to the evaporator is generally in a fully open state to improve heating efficiency; that is, in the present disclosure, the opening degree of the first damper during the pre-defrost stage is generally at an opening degree corresponding to position 10, so as to transfer heat from the evaporator side to the environment; when the pre-defrost stage or the defrost stage is within the sixth preset period or the temperature difference between the evaporator and the environment is large, the opening degree of the first damper is still controlled to an opening degree corresponding to position 10 to improve heating efficiency; when the temperature difference between the evaporator and the environment is not large or the defrost period reaches the sixth preset period, the opening degree of the first damper is adjusted.

[0080] For example, the method may further include adjusting the opening degree of the first damper to a third target opening degree when a difference between the evaporator pipe temperature and the ambient temperature of the integrated air conditioner is within a preset range and / or the duration during which the integrated air conditioner operates in the cooling mode reaches a sixth preset duration.

[0081] The preset range is [-5°C, 5°C], and when the difference between the evaporator pipe temperature and the ambient temperature of the integrated air conditioner is within the preset range, it indicates that the difference between the evaporator pipe temperature and the ambient temperature is not large. At this time, to avoid affecting the ambient temperature during the defrosting process, the opening degree of the first damper can be adjusted from the opening degree corresponding to position 10 to the opening degree corresponding to position 0. The sixth preset period is 20 seconds, that is, after the integrated air conditioner has been operating in cooling mode for 20 seconds, the opening degree of the first damper can be adjusted from the opening degree corresponding to position 10 to the opening degree corresponding to position 0.

[0082]

[0023] Using the above technical solution, when the difference between the evaporator pipe temperature and the ambient temperature is large, the opening of the first damper is not adjusted, thereby transferring heat from the evaporator to the ambient temperature, effectively raising the ambient temperature and using the ambient temperature to provide more heat to the condenser during the defrosting stage. Furthermore, if the difference between the evaporator pipe temperature and the ambient temperature of the integrated air conditioner is within a preset range and / or the duration that the integrated air conditioner has been operating in cooling mode reaches a sixth preset duration, the opening of the first damper is adjusted to the third target opening, preventing user discomfort due to the impact of the ambient temperature during the defrosting process.

[0083] When the condenser is defrosted by the above method and it is detected that the integrated air conditioner satisfies the preset defrost termination condition, the operation mode of the integrated air conditioner can be switched from the cooling mode to the heating mode to satisfy the user's heating request. Therefore, in the present disclosure, the method may further include switching the operation mode of the integrated air conditioner from the cooling mode to the heating mode in response to the integrated air conditioner satisfying the preset defrost termination condition.

[0084] The defrost termination conditions may include at least one of the following: the duration of the defrosting stage reaches 9 minutes; the evaporator pipe temperature is higher than 0°C after 4 minutes of defrosting and rises to above 2°C within 10 seconds; the evaporator pipe temperature is higher than 5°C after 4 minutes of defrosting.

[0085] By using the above technical solution, when it is determined that the integrated air conditioner meets the preset defrost termination condition, the operation mode of the integrated air conditioner is automatically controlled to switch from cooling mode to heating mode, so as to meet the user's heating requirements and further improve the user's usability.

[0086] After the defrosting is completed, the integrated air conditioner enters a defrost exit phase, during which the operating mode of the integrated air conditioner switches from cooling mode to heating mode. In one embodiment, the integrated air conditioner includes a four-way valve, and switches the operating mode of the integrated air conditioner from cooling mode to heating mode in response to the integrated air conditioner satisfying a preset defrost exit condition. In a specific embodiment, in response to the integrated air conditioner satisfying the preset defrost exit condition, the compressor is stopped and the four-way valve is controlled to be powered on. When the compressor has been stopped for a seventh preset period and the four-way valve is in the power-on state, the compressor is controlled to switch the operating mode of the integrated air conditioner from cooling mode to heating mode.

[0087] Similarly, when switching from cooling mode to heating mode, the direction of the four-way valve needs to be switched, so the compressor needs to be controlled to stop operating, the heat exchange system needs to be maintained in a pressure equilibrium state, and the four-way valve needs to be controlled to be powered on when the heat exchange system is in a pressure equilibrium state.

[0088] In this embodiment, the compressor is stopped during a seventh preset period to allow the four-way valve to complete power-on operation during the seventh preset period, for example, the seventh preset period may be 50 seconds.

[0089] In a possible method of this embodiment, when it is determined that the integrated air conditioner satisfies the preset defrost termination condition, the four-way valve is directly controlled to be powered on. However, since the power-on of the four-way valve and the operation of the compressor are controlled simultaneously, a situation may occur in which the four-way valve is controlled to be powered on when the heat exchange system is not in a pressure equilibrium state, which may result in the four-way valve not being successfully powered on.

[0090] To ensure successful direction switching of the four-way valve when the heat exchange system is in a pressure equilibrium state, in another possible method of this embodiment, the four-way valve may be controlled to be powered on after the compressor has been stopped for a certain period of time. For example, controlling the four-way valve to be powered on in response to the integrated air conditioner satisfying the preset defrost termination condition may include controlling the four-way valve to be powered on after an eighth preset period that is shorter than the seventh preset period in response to the integrated air conditioner satisfying the preset defrost termination condition.

[0091] For example, the eighth preset period is 40 seconds and the seventh preset period is 50 seconds. When it is determined that the integrated air conditioner meets the preset defrost termination conditions, the compressor is controlled to stop operating, and after a delay of 40 seconds, the four-way valve is controlled to power on. When the compressor has been stopped for 50 seconds and the four-way valve is in the power-on state, the compressor is started, thereby switching the operating mode of the integrated air conditioner from cooling mode to heating mode. In heating mode, the operating frequency of the compressor is in the range of 10 Hz to 110 Hz.

[0092] The integrated air conditioner may further include an expansion valve, and switching the operation mode of the integrated air conditioner to the heating mode in response to the integrated air conditioner satisfying the preset defrost termination condition may further include controlling the expansion valve to operate at a preset maximum valve opening in response to the integrated air conditioner satisfying the preset defrost condition.

[0093] In order to ensure that the heat exchange system is in a pressure-balanced state during the defrost exit phase, the expansion valve can be further controlled to operate at a preset maximum valve opening, for example, the maximum valve opening is 480, and at this time, the expansion valve can be operated at the maximum valve opening to further balance the pressure of the heat exchange system. When the integrated air conditioner is operating in a heating mode, the expansion valve can also be controlled to operate at a second preset valve opening, which is smaller than or equal to the maximum valve opening. For example, the value range of the second preset valve opening is [100, 480].

[0094] In addition, during the defrost exit stage, the fan blade motor can be controlled to operate at a target rotation speed, which may be the rotation speed of the fan blade motor when the integrated air conditioner is in heating mode before the defrost preparation stage. For example, the target rotation speed may be in the range of 450 RPM to 900 RPM.

[0095] During the defrost exit stage, the opening degrees of the first and second dampers are not adjusted temporarily, and after the integrated air conditioner enters the heating mode, the opening degrees of the first and second dampers are adjusted. The method for adjusting the first and second dampers in the heating mode has been described above and will not be described again here.

[0096] Next, a control method for an all-in-one air conditioner provided in this disclosure will be described as a complete embodiment. The method can be divided into four stages: a defrost preparation stage, a defrost stage, a defrost exit stage, and a heating and cold wind prevention stage. In each stage, the fan blade motor, first damper, second damper, compressor, expansion valve, and four-way valve of the all-in-one air conditioner are controlled.
