Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a control method, control device, and oxygen-generating air conditioner. Background Technology

[0002] In order to reduce the heat exchange between indoor and outdoor environments, indoor air conditioning usually sets the indoor environment to a closed state, which leads to the continuous consumption of indoor oxygen without timely replenishment.

[0003] To address this issue, one approach to increasing indoor oxygen levels involves introducing ambient air into the room. However, this method inevitably increases the load on the air conditioning system and is limited by the quality of the outside air. Another approach combines an oxygen concentrator with an air conditioner. The oxygen produced by the concentrator is then delivered into the room via airflow, creating an oxygen-rich environment while having lower requirements for outside air quality. However, oxygen-concentrating air conditioners, which include the compressor of the refrigeration system, the compressor for oxygen generation, and the outdoor unit fan, have numerous motors, high vibration frequencies, and significant noise. Resonance is a real possibility, amplifying system noise and potentially damaging the oxygen-concentrating air conditioner. Summary of the Invention

[0008] In the event of a resonance risk, the oxygen compressor, the air conditioning compressor, and / or the outdoor fan are controlled based on the indoor oxygen concentration.

[0009] In this embodiment, when there is a risk of resonance in the oxygen generator compressor, air conditioner compressor, and outdoor fan, the oxygen generator compressor, air conditioner compressor, and outdoor fan are regulated based on the indoor oxygen concentration. This effectively prevents resonance, reduces the operating noise of the oxygen generator air conditioner, and ensures that the indoor oxygen concentration is within the range of the user's optimal comfort level, thus improving the user experience.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0040] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0041] Existing oxygen-generating air conditioners include compressors for the refrigeration system, compressors for oxygen generation, and fans for the outdoor unit. They have a large number of motors, high vibration frequency, and loud noise, which may lead to resonance. This not only amplifies the system noise but also damages the oxygen-generating air conditioner.

[0042] To address the above technical problems, this embodiment proposes a control method for an oxygen-generating air conditioner. The oxygen-generating air conditioner includes an oxygen generator and an outdoor unit. The oxygen generator is located in the outdoor unit and includes an oxygen compressor. The outdoor unit includes an air conditioning compressor and an outdoor fan. The control method includes:

[0043] When the oxygen concentrator is in the oxygen-generating state, obtain the operating frequencies of the oxygen compressor, air conditioning compressor, and outdoor fan;

[0044] Determine whether there is a risk of resonance based on the operating frequencies of the oxygen compressor, air conditioning compressor, and outdoor fan.

[0045] In cases where there is a risk of resonance, the oxygen compressor, air conditioning compressor, and / or outdoor fan should be controlled based on the indoor oxygen concentration.

[0046] In this embodiment, when there is a risk of resonance in the oxygen generator compressor, air conditioner compressor, and outdoor fan, the oxygen generator compressor, air conditioner compressor, and outdoor fan are regulated based on the indoor oxygen concentration. This effectively prevents resonance, reduces the operating noise of the oxygen generator air conditioner, and ensures that the indoor oxygen concentration is within the range of the user's optimal comfort level, thus improving the user experience.

[0047] First, a brief introduction will be given to the main body of the oxygen-generating air conditioner in this embodiment.

[0048] An oxygen-generating air conditioner consists of an indoor unit, an outdoor unit, and an oxygen generator. The indoor unit includes an inner casing, air ducts, an outdoor fan, and an indoor heat exchanger. The casing has an air inlet and an air outlet. For wall-mounted indoor units, the air inlet is generally located at the top of the casing, and the air outlet is located at the lower front of the casing. However, the location of the air inlet is not limited to this and can be flexibly designed according to needs. The arrangement of the outdoor fan, air ducts, and indoor heat exchanger is similar to that of a conventional air conditioner indoor unit and will not be described in detail here.

[0049] The outdoor unit includes the outdoor unit casing, air conditioning compressor, outdoor fan, and outdoor heat exchanger. The arrangement of the outdoor unit casing, air conditioning compressor, outdoor fan, and outdoor heat exchanger is similar to that of the outdoor unit of a conventional air conditioner, and will not be described in detail here.

[0050] An oxygen concentrator includes components such as an oxygen compressor, filters, and molecular sieves. The specific structure of the oxygen concentrator is existing technology and will not be described in detail here. The oxygen concentrator has an oxygen outlet, which is connected to the air inlet and / or outlet of the indoor unit via an oxygen delivery pipeline. This allows the oxygen generated by the concentrator to be blown into the indoor environment along with the airflow from the outlet. In a preferred embodiment, the oxygen outlet of the oxygen concentrator is connected to the air inlet of the indoor unit. This allows the oxygen generated by the concentrator to be blown into the room along with the indoor air after heat exchange, improving indoor comfort.

[0051] The oxygen concentrator is located in the outdoor environment where the outdoor unit is situated, and its placement on the outdoor unit reduces the impact of noise from the oxygen concentrator's startup on users indoors. More preferably, the oxygen concentrator and outdoor unit are integrated into one unit to minimize the space occupied by the oxygen concentrator.

[0052] The oxygen-generating air conditioner also includes an oxygen concentration detection device, which is located at the oxygen outlet of the indoor unit, away from the oxygen delivery pipeline, to accurately detect the indoor oxygen concentration in the environment where the indoor unit is located. In one example, the oxygen outlet is connected to the air outlet via an oxygen delivery pipeline, and the oxygen concentration detection device is located at the air inlet.

[0053] The control method of this embodiment will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and examples can be combined with each other.

[0054] This embodiment proposes a control method for an oxygen generator air conditioner, referring to... Figure 1 The flowchart and control method include the following steps:

[0055] S11. When the oxygen generator is in the oxygen-generating state, obtain the operating frequencies of the oxygen compressor, air conditioning compressor and outdoor fan.

[0056] Specifically, in combination Figure 3 The flowchart illustrates that the oxygen-generating air conditioner starts upon receiving a user's control command and operates in cooling, heating, or dehumidifying mode according to the user's instructions. When the oxygen-generating air conditioner is running, the compressor and outdoor fan are operational. The oxygen generator can be started based on user commands or automatically based on the detected indoor oxygen concentration.

[0057] When the oxygen generator is running, the oxygen compressor is in operation. To avoid resonance between the oxygen compressor, air conditioning compressor, and outdoor fan, the operating frequencies f1, f2, and f3 of the oxygen compressor, air conditioning compressor, outdoor fan, and outdoor fan need to be checked in real time or periodically after they are in stable operation. The presence of resonance risk can be determined based on the detected operating frequencies.

[0058] S12. Determine whether there is a risk of resonance based on the operating frequencies of the oxygen compressor, air conditioning compressor, and outdoor fan.

[0059] Specifically, in combination Figure 3 The flowchart illustrates that after determining the operating frequency f3 of the oxygen generator compressor, the operating frequency f1 of the air conditioning compressor, and the operating frequency f2 of the outdoor fan, a resonance risk can be determined based on the proximity of the operating frequencies of the oxygen generator compressor to the air conditioning compressor and / or the outdoor fan. In a specific example, a resonance risk is determined to exist when the following conditions are met: the difference between the operating frequency f3 of the oxygen generator compressor and the operating frequency f1 of the air conditioning compressor is within a first preset difference range; and / or, the difference between the operating frequency f3 of the oxygen generator compressor and the operating frequency f2 of the outdoor fan is within a second preset difference range; and / or, the difference between the operating frequency f1 of the air conditioning compressor and the operating frequency f2 of the outdoor fan is within a third preset difference range.

[0060] S13. In the event of a resonance risk, control the oxygen compressor, air conditioning compressor and / or outdoor fan according to the indoor oxygen concentration.

[0061] Specifically, in combination Figure 3 The flowchart illustrates that, if a resonance risk is identified, failure to adjust the oxygen compressor, air conditioning compressor, and outdoor fan will lead to increased noise, causing user discomfort. Furthermore, resonance will affect the reliability of the outdoor unit. Since the oxygen generator is starting, it indicates that the indoor oxygen concentration may not have reached the optimal range (X1, X2). Therefore, it is necessary to monitor the indoor oxygen concentration X in real-time or periodically, and adjust the oxygen compressor, air conditioning compressor, and / or outdoor fan accordingly. This ensures that the indoor oxygen concentration reaches the optimal range (X1, X2) while preventing resonance and effectively reducing the operating noise of the oxygen-generating air conditioner.

[0062] In one alternative implementation, combined Figure 3 The flowchart describes how to control the oxygen generator compressor, air conditioning compressor, and / or outdoor fan based on the indoor oxygen concentration. This includes: when the indoor oxygen concentration X is less than the maximum value X2 of the preset oxygen concentration range, it indicates that the indoor oxygen concentration X has not yet exceeded the optimal oxygen concentration range. The oxygen generator needs to remain running. In this case, the operating frequency of the oxygen generator compressor, air conditioning compressor, and / or outdoor fan is adjusted according to the indoor oxygen concentration X to ensure that the indoor oxygen concentration reaches the optimal concentration range (X1, X2) while avoiding resonance. When the indoor oxygen concentration X is greater than the maximum value X2 of the preset oxygen concentration range, it indicates that the indoor oxygen concentration has exceeded the optimal oxygen concentration range (X1, X2), and there is no need to continue oxygen production. Therefore, the oxygen generator compressor can be shut down, reducing energy consumption and avoiding resonance.

[0063] In one alternative implementation, combined Figure 3 The flowchart describes adjusting the operating frequencies of the oxygen generator compressor, air conditioner compressor, and / or outdoor fan based on the indoor oxygen concentration. This includes: when the indoor oxygen concentration X is lower than the minimum value X1 of the preset oxygen concentration range, it indicates that the indoor oxygen concentration X has not yet reached the optimal oxygen concentration range (X1, X2). Reducing the operating frequency of the oxygen generator will affect the efficiency of increasing the indoor oxygen concentration. Therefore, the operating frequencies of the air conditioner compressor and / or outdoor fan can be adjusted to increase the frequency difference between the air conditioner compressor and the outdoor fan, ensuring that the indoor oxygen concentration reaches the optimal concentration range (X1, X2) while avoiding resonance.

[0064] In specific implementation methods, increasing the difference in operating frequencies between the air conditioner compressor and the outdoor fan includes increasing the operating frequency of one of the air conditioner compressor and the outdoor fan, and decreasing the operating frequency of the other. For example, the operating frequency of the air conditioner compressor f1 is increased by 5Hz, and the operating frequency of the outdoor fan f2 is decreased by 5Hz.

[0065] Alternatively, adjust the operating frequency of only one of the air conditioner compressor and the outdoor fan; or simultaneously increase or decrease the operating frequencies of the air conditioner compressor and the outdoor fan, with different adjustment values ​​for the operating frequencies of the air conditioner compressor and the outdoor fan.

[0066] If the indoor oxygen concentration is within the preset range, it means that the indoor oxygen concentration X has reached the optimal range. At this point, the operating frequency of the oxygen generator compressor can be reduced to maintain the indoor oxygen concentration within the optimal range (X1, X2). For example, the operating frequency of the oxygen generator compressor can be reduced by 5Hz.

[0067] In one alternative implementation, combined Figure 3The flowchart shows that when the indoor oxygen concentration X is lower than the minimum value X1 of the preset oxygen concentration range, the working frequency f3 of the oxygen generator compressor is kept constant to ensure the oxygen generation efficiency of the oxygen generator.

[0068] And / or, when the indoor oxygen concentration X is within the preset oxygen concentration range (X1, X2), the operating frequencies f1 and f2 of the air conditioning compressor and outdoor fan are kept constant to ensure the comfort of the indoor ambient temperature.

[0069] In one alternative implementation, refer to Figure 2 The flowchart and control method also include the following steps:

[0070] S21. When the indoor oxygen concentration is lower than the minimum value of the preset oxygen concentration range, the indoor ambient temperature is also obtained.

[0071] S22. Adjust the operating frequency of the outdoor fan and / or air conditioning compressor according to the operating mode of the oxygen generator air conditioner and the indoor ambient temperature.

[0072] Specifically, when the indoor oxygen concentration X is lower than the minimum value X1 of the preset oxygen concentration range (X1, X2), it is necessary to adjust the operating frequency f1 of the air conditioner compressor and the operating frequency f2 of the outdoor fan to avoid resonance. To prevent the adjustment of the air conditioner compressor and outdoor fan operating frequencies from affecting the indoor ambient temperature, this embodiment also obtains the indoor ambient temperature and then combines the indoor ambient temperature with the operating mode of the air conditioner to adjust the operating frequencies of the outdoor fan and air conditioner compressor, thereby ensuring comfortable indoor ambient temperature.

[0073] In one alternative implementation, the operating frequency of the outdoor fan and / or the air conditioning compressor is adjusted according to the operating mode of the oxygen generator air conditioner and the indoor ambient temperature, including:

[0074] In cooling mode, if the indoor ambient temperature is less than or equal to the first set temperature, it means that the indoor ambient temperature has reached the user's set temperature. At this time, the operating frequency of the air conditioner compressor can be reduced and the operating frequency of the outdoor fan can be increased. This avoids resonance and prevents the indoor ambient temperature from becoming too low, while also reducing energy consumption. If the indoor ambient temperature is higher than the first set temperature, it means that the indoor ambient temperature is higher than the user's set temperature. At this time, the operating frequency of the air conditioner compressor can be increased and the operating frequency of the outdoor fan can be reduced. This avoids resonance and can also quickly reduce the indoor ambient temperature to the first set temperature.

[0075] In heating mode, if the indoor ambient temperature is greater than or equal to the second set temperature, it means that the indoor ambient temperature has reached the user's set temperature. At this time, the operating frequency of the air conditioner compressor is reduced and the operating frequency of the outdoor fan is increased. This avoids resonance and prevents the indoor ambient temperature from becoming too high, while also reducing energy consumption. If the indoor ambient temperature is less than the second set temperature, it means that the indoor ambient temperature is lower than the user's set temperature. At this time, the operating frequency of the air conditioner compressor needs to be increased and the operating frequency of the outdoor fan needs to be reduced. This avoids resonance and also allows the indoor ambient temperature to rise quickly to the second set temperature.

[0076] In one alternative implementation, adjusting the operating frequency of the outdoor fan and the air conditioning compressor based on the operating mode of the oxygen generator and / or the indoor ambient temperature includes:

[0077] In cooling mode, if the indoor ambient temperature is less than or equal to the first set temperature, it indicates that the indoor ambient temperature has reached the user-set temperature. At this point, the operating frequencies of both the air conditioner compressor and the outdoor fan are simultaneously reduced, but the reduction in the compressor frequency differs from the reduction in the outdoor fan frequency. This avoids resonance, prevents the indoor ambient temperature from becoming too low, and reduces energy consumption. For example, the compressor frequency is reduced by 10Hz, and the outdoor fan frequency is reduced by 5Hz.

[0078] If the indoor ambient temperature is higher than the first set temperature, it indicates that the indoor ambient temperature is already higher than the user-set temperature. The operating frequencies of both the air conditioner compressor and the outdoor fan are simultaneously increased, but the increase in the compressor frequency differs from the increase in the outdoor fan frequency. This avoids resonance while rapidly lowering the indoor ambient temperature to the first set temperature. For example, the compressor frequency is increased by 10Hz, and the outdoor fan frequency is increased by 5Hz.

[0079] In heating mode, if the indoor ambient temperature is greater than or equal to the second set temperature, it indicates that the indoor ambient temperature has reached the user-set temperature. At this point, the operating frequencies of both the air conditioner compressor and the outdoor fan are simultaneously reduced, but the reduction in the compressor frequency is different from the reduction in the outdoor fan frequency. This avoids resonance, prevents the indoor ambient temperature from becoming too high, and reduces energy consumption. For example, the compressor frequency is reduced by 10Hz, and the outdoor fan frequency is reduced by 5Hz.

[0080] If the indoor ambient temperature is lower than the second set temperature, it indicates that the indoor ambient temperature is already below the user's set temperature. The operating frequencies of both the air conditioner compressor and the outdoor fan are simultaneously increased, with the increase in the compressor frequency differing from that of the outdoor fan. This avoids resonance while rapidly raising the indoor ambient temperature to the second set temperature. For example, the compressor frequency is increased by 10Hz, and the outdoor fan frequency is increased by 5Hz.

[0081] In summary, this embodiment monitors the operating frequencies of the oxygen concentrator compressor, the air conditioning compressor, and the outdoor fan when the oxygen concentrator is running. When there is a risk of resonance among these three components, the indoor oxygen concentration is monitored, and the oxygen concentrator compressor, the air conditioning compressor, and the outdoor fan are adjusted based on the indoor oxygen concentration. This avoids resonance, reduces the operating noise of the oxygen concentrator air conditioner, effectively ensures the indoor oxygen concentration, and also ensures the comfort of the indoor ambient temperature, thus improving the user experience.

The communication bus 200 is configured to enable communication between these components.
