Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an anti-condensation device, an air conditioner, and an anti-condensation control method. Background Technology

[0002] When users turn on the air conditioner for cooling or dehumidification in environments with high indoor humidity, the air outlet will produce condensation due to the prolonged supply of cold air. This can cause the air conditioner to blow water, and in the case of cabinet air conditioners with both upper and lower air outlets, the condensation can flow back into the air conditioner, leading to malfunctions, user complaints, and a negative impact on user experience.

[0003] To address this issue, existing technologies aim to balance the airflow at the top and bottom of the vent by altering the direction and speed of the airflow, thereby reducing condensation caused by excessive localized temperatures. However, this method only reduces uneven temperature distribution at the vent; condensation will still occur when the vent temperature is too low, potentially leading to air conditioning malfunctions.

[0004] In addition, existing technologies also use heating devices to raise the temperature of the air outlet to prevent condensation from forming at the outlet. However, this affects the cold air output and reduces the efficiency of cooling or dehumidification. Summary of the Invention

[0005] One of the objectives of this invention is to provide an anti-condensation device that avoids the shortcomings of the prior art. This anti-condensation device can switch between different air outlets to avoid the problem of condensation caused by a single air outlet blowing cold air for a long time.

[0006] The second objective of this invention is to provide an air conditioner.

[0007] The third objective of this invention is to provide a method for controlling condensation.

[0008] To achieve one of the above objectives, the present invention provides the following technical solution:

[0009] A device for preventing condensation is provided, comprising:

[0010] Air duct 1,

[0011] Fan 2, which is installed inside the air duct 1;

[0012] The first air outlet 4 and the second air outlet 5 are distributed on both sides of the air duct 1 with the central axis of the cross-section of the air duct as the center of symmetry and are respectively connected to the air duct 1.

[0013] The first baffle is located at the first air outlet 4 and is used to control the connection between the first air outlet and the air duct 1.

[0014] The second baffle is located at the second air outlet 5 and is used to control the connection between the second air outlet 5 and the air duct 1.

[0015] Adding baffles to the air outlets connected to the air ducts can control the air conditioning airflow pattern, allowing for alternating airflow and reducing the cooling time of individual air outlets, thus achieving the effect of preventing condensation.

[0016] In some embodiments, a housing 3 is also included, the air duct 1 is disposed inside the housing 3, and the air duct 1 extends outward to form the first air outlet 4 and the second air outlet 5 on the housing 3.

[0017] The aforementioned air outlet is formed by extending outward from the air duct, allowing the air from the air duct to be easily discharged from the air outlet.

[0018] In some embodiments, the first air outlet 4 is located above the air duct, and the second air outlet 5 is located below the air duct.

[0019] The first air outlet 4 is rotated 180° around the central axis of the cross-section of the air duct to obtain the second air outlet 5.

[0020] In practical applications, only two air outlets are needed. When one air outlet is cooled for too long, switch to the other air outlet. Alternating in this way can solve the problem of avoiding a single air outlet being blown by cold air for a long time.

[0021] In some embodiments, a controller is also included, with the first baffle and the second baffle respectively connected to the controller, and the controller controls each baffle to open or close its respective air outlet.

[0022] The controller controls the opening or closing of the baffle based on the relationship between the air outlet temperature and the indoor ambient temperature, or based on the indoor ambient humidity.

[0023] The beneficial effects of the anti-condensation device of the present invention are as follows:

[0024] The anti-condensation device of the present invention has a first air outlet and a second air outlet on the air duct, and a baffle is provided on the air outlet to control the connection between the air outlet and the air duct. When condensation occurs at a certain air outlet due to its temperature being lower than the indoor ambient temperature, the connection between the air outlet and the air duct is controlled by the baffle to switch to a different air outlet, thus avoiding the problem of condensation easily occurring at a certain air outlet due to its low temperature. Furthermore, the anti-condensation device has a simple structure, is easy to operate, and is suitable for large-scale production applications.

[0025] To achieve the second objective mentioned above, the present invention provides the following technical solution:

[0026] An air conditioner is provided that includes the aforementioned anti-condensation device.

[0027] To achieve the third objective mentioned above, the present invention provides the following technical solution:

[0028] A control method for preventing condensation in an air conditioner is provided. The control method includes the following steps:

[0029] S1. Obtain the time t required for the indoor ambient temperature to decrease by m℃;

[0030] S2. Determine if t≤t1, where t1 is a set time value. If t≤t1, open all baffles to allow all air outlets to blow air simultaneously.

[0031] If t > t1, then close one of the air outlets and open the other. Then determine if there is a risk of condensation at the currently opened air outlet. The step of determining whether there is a risk of condensation at the currently opened air outlet includes:

[0032] Air conditioner continues to run for t m Then, obtain the temperature T of the currently open air outlet. 出风口 And obtain the dew point temperature T of the indoor environment at this time. 露 Determine if T 出风口 ≤T 露 +T 设 T 设 ≥0;

[0033] If T 出风口 ≤T 露 +T 设 If there is a risk of condensation, switch the air outlet to close the currently open air outlet and open at least one currently closed air outlet.

[0034] If T 出风口 >T 露 +T 设 If there is no risk of condensation, then do not switch the air outlet and proceed to step S1.

[0035] The above control method detects the indoor ambient temperature, temperature drop time, and indoor unit air outlet temperature to control the air conditioner's air outlet mode, alternating air outlets to reduce the cooling time of individual air outlets and achieve the effect of preventing condensation.

[0036] The working principle of the above control method is as follows: First, the cooling rate of the indoor environment is judged to determine whether most of the cold air produced by the air conditioner is used for cooling. If the cooling rate is fast, when t is less than or equal to the set time t1, it means that most of the cold air is used for cooling, indicating that the ambient humidity is low and condensation will not occur at the air outlet. At this time, all air outlets can be kept open without switching the air outlets. If the cooling rate is slow, when t is greater than the set time t1, it means that most of the cold air is used for dehumidification, indicating that the ambient humidity is high and condensation is likely to occur at the air outlets. At this time, switching the air outlets reduces the cooling time of a single air outlet, thereby preventing condensation from occurring when a single air outlet is cooled for a long time. This completely eliminates condensation and avoids condensation. At the same time, during the process of switching the air outlets, the temperature of the open air outlet is monitored to see if it reaches the dew point of the indoor environment, and the air outlet is switched in time to further prevent condensation from occurring at the open air outlets.

[0037] In some implementations, step S1 is executed when the air conditioner is turned on for cooling or dehumidification.

[0038] Since the problem of prolonged exposure to cold air at the air outlet only occurs when the air conditioner is turned on for cooling or dehumidification, resulting in condensation at the air outlet, the aforementioned air conditioner anti-condensation control method should be implemented when the air conditioner is turned on for cooling or dehumidification.

[0039] In some embodiments, in step S2, when one of the air outlets is closed, the fan speed 2 is increased and / or the compressor frequency is increased.

[0040] Increasing the indoor motor speed and compressor frequency, and ensuring the outlet air temperature, achieves the effect of preventing condensation while meeting user comfort requirements, thus improving the user experience.

[0041] In some implementations, in step S2, the value of t1 is set according to the air conditioner's operating fan speed, wherein the higher the fan speed, the smaller the corresponding t1 value.

[0042] In some implementations, in step S2, after switching the air outlet, the step of determining whether there is a risk of condensation at the currently opened air outlet is repeated.

[0043] The beneficial effects of the anti-condensation control method of the present invention are as follows:

[0044] (1) The anti-condensation control method of the present invention first determines whether most of the cold air generated by the air conditioner is used for cooling by judging the cooling rate of the indoor environment. If the cooling rate is fast, then when t is less than or equal to the set time t1, it means that most of the cold air is used for cooling, indicating that the ambient humidity is low and the air outlet will not produce condensation. At this time, all air outlets can be kept open without switching the air outlets. If the cooling rate is slow, then when t is greater than the set time t1, it means that most of the cold air is used for dehumidification, indicating that the ambient humidity is high and the air outlet is prone to condensation. At this time, the air outlet is switched to reduce the cooling time of a single air outlet, thereby preventing the problem of condensation from occurring when a single air outlet is cooled for a long time. This can completely eliminate the generation of condensation and avoid condensation. At the same time, during the process of switching the air outlet, the temperature of the opened air outlet is monitored to see if it reaches the dew point of the indoor environment, and then the air outlet is switched in time to further prevent condensation from occurring at the opened air outlet.

[0045] (2) The anti-condensation control method of the present invention can prevent condensation without adding a heating device, so that rapid cooling or dehumidification can be achieved simultaneously in the anti-condensation mode; and can avoid indoor temperature fluctuations caused by heating, thus improving comfort.

[0046] (3) The anti-condensation control method of the present invention can stably prevent the generation of condensate and ensure normal air supply. Moreover, the control method is simple and suitable for large-scale production applications. Attached Figure Description

Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0057] When users turn on the air conditioner for cooling or dehumidification in environments with high indoor humidity, the air outlet will produce condensation due to the prolonged supply of cold air. This can cause the air conditioner to blow water, and in the case of cabinet air conditioners with both upper and lower air outlets, the condensation can flow back into the air conditioner, leading to malfunctions, user complaints, and a negative impact on user experience.

[0058] To address this issue, existing technologies only change the direction and speed of airflow at the air outlet, reducing condensation caused by excessive localized temperature by balancing the airflow volume at the top and bottom of the outlet. However, this method only reduces uneven temperature at the air outlet; condensation will still occur when the outlet temperature is too low, leading to air conditioner malfunctions.

[0059] Example 1

[0060] Please see Figures 1-4 This embodiment discloses an anti-condensation device, comprising:

[0061] Air duct 1, which is used to install fan 2;

[0062] Specifically, the shape of the air duct 1 can be designed according to the specific structure of the fan 2; for example, the air duct 1 is a long cylindrical shape, used to install the long cylindrical fan 2.

[0063] Fan 2, which is installed inside the air duct 1.

[0064] The first air outlet (4) and the second air outlet (5) are distributed on both sides of the air duct (1) with the central axis of the cross-section of the air duct as the center of symmetry and are respectively connected to the air duct (1). The air outlet is used to discharge the air inside the air duct 1. Specifically, the air outlet is an opening connected to the side of the air duct 1, so that the air volume generated by the fan 2 inside the air duct 1 can be discharged from the air outlet. Furthermore, the first air outlet (4) and the second air outlet (5) are distributed on both sides of the air duct (1) with the central axis of the cross-section of the air duct as the center of symmetry, so that the first air outlet and the second air outlet can discharge air symmetrically, increasing the comfort of air discharge.

[0065] The first baffle 61 is disposed at the first air outlet (4) and is used to control the connection state between the first air outlet 4 and the air duct (1).

[0066] The second baffle 62 is provided at the second air outlet (5) and is used to control the connection state between the second air outlet (5) and the air duct (1).

[0067] Specifically, the baffle is set at the connection between the air outlet and the air duct 1. When the baffle is closed, it closes the connection between the air outlet and the air duct 1. When the baffle is open, it avoids the connection between the air outlet and the air duct 1.

[0068] In practical applications, one side of the baffle is hinged to the inner wall of the air duct 1, and the baffle can be easily opened or closed around the hinge axis.

[0069] The aforementioned anti-condensation device has multiple air outlets on the air duct 1, and baffles are installed on the air outlets to control the connection between the air outlets and the air duct 1. When condensation occurs at a certain air outlet due to its temperature being lower than the indoor ambient temperature, the connection between the air outlet and the air duct 1 is controlled by the baffles, thereby changing to a different air outlet. This avoids the problem of condensation easily occurring at a certain air outlet due to its low temperature. Furthermore, the anti-condensation device has a simple structure, is easy to operate, and is suitable for large-scale production applications.

[0070] Example 2

[0071] Please see Figures 1-4In order to make reasonable arrangement of air duct 1 and air outlet, based on embodiment 1, this embodiment discloses that the air duct 1 is set inside the housing 3, and the air duct 1 extends outward to form a first air outlet 4 and a second air outlet 5 on the housing 3.

[0072] Specifically, the air duct 1 is formed on the housing 3, and then the air outlet is formed on the housing 3, wherein the air outlet is formed by extending outward from the air duct 1.

[0073] The aforementioned air outlet is formed by extending outward from the air duct 1, allowing the air from the air duct 1 to be conveniently discharged from the air outlet.

[0074] Example 3

[0075] Please see Figures 1-4 If there are too many air outlets, it will increase the manufacturing difficulty on the one hand, and increase the complexity of switching air outlets on the other hand. Therefore, based on Embodiment 1, this embodiment discloses at least two air outlets, including a first air outlet 4 and a second air outlet 5.

[0076] In practical applications, only two air outlets are needed. When one air outlet is cooled for too long, switch to the other air outlet. Alternating in this way can solve the problem of avoiding a single air outlet being blown by cold air for a long time.

[0077] Furthermore, the first air outlet 4 and the second air outlet 5 are distributed on both sides of the air duct 1 with the axis of symmetry of the cross-section of the air duct 1 as the axis of symmetry.

[0078] Furthermore,

[0079] The first air outlet 4 is positioned above the cross-section of the air duct 1, and the second air outlet 5 is positioned below the cross-section of the air duct 1. The first air outlet 4 is rotated 180° around the central axis of the cross-section of the air duct to obtain the second air outlet 5. At this time, the first air outlet 4 and the second air outlet 5 are preferably positioned above and below the cross-section of the air duct 1.

[0080] The advantages of this are:

[0081] The air conditioner can blow cold air from top to bottom, that is, the cold air blows upwards and then falls back to the ground, so that the cold air can better cover the entire indoor space, improve the utilization rate of the cold air, and at the same time avoid the problem of cold air blowing directly on people, which would cause discomfort.

[0082] Therefore, in practical applications, when switching air outlets, the first air outlet 4 located above the cross-section of the air duct 1 should be the first to discharge air until there is a risk of condensation at the first air outlet 4, at which point the second air outlet 5 should be switched. This ensures the priority of the first air outlet 4 and guarantees the comfort of cooling.

[0083] Example 4

[0084] Based on Embodiment 1, this embodiment also includes a controller, with the first baffle 61 and the second baffle 62 respectively connected to the controller, and the controller controlling the first baffle 61 and the second baffle 62 to open or close their respective air outlets.

[0085] In practical applications, the controller controls the opening or closing of the baffle based on the relationship between the outlet temperature and the indoor ambient temperature. Specifically, when the outlet temperature is lower than the indoor ambient temperature, the controller switches the outlet to prevent a single outlet from being cooled for too long, which could lead to condensation at that outlet.

[0086] Alternatively, the opening or closing status of the baffle can be controlled according to the indoor humidity. Specifically, when the indoor humidity is high, condensation is likely to occur, and the air outlet method needs to be switched to avoid condensation at the air outlet. When the indoor humidity is low, it is not necessary to open all air outlets.

[0087] Example 5

[0088] Please see Figures 1-5 Based on the above embodiments, this embodiment discloses a control method for preventing condensation in air conditioners, including the following steps:

[0089] S1. Obtain the time t required for the indoor ambient temperature to decrease by m℃;

[0090] S2. Determine if t≤t1, where t1 is a set time value;

[0091] For example, the time t required for the indoor ambient temperature to decrease by 3°C is obtained, and it is determined whether t≤t1, where t1 is a set time value, and for example, t1 is 15min.

[0092] Furthermore, the value of t1 is set according to the air conditioner's operating fan speed, wherein the higher the fan speed, the smaller the value of t1.

[0093] Different air conditioner fan speeds result in different airflow settings. Higher fan speeds result in higher airflow and shorter cooling times. Therefore, the fan speed setting is inversely proportional to the value of t1, allowing for a more accurate determination of indoor humidity.

[0094] By judging the relationship between t≤t1, the indoor humidity status can be known. Specifically: if t is less than or equal to the set time t1, it means that the cooling speed is fast. At this time, most of the cold air is used for cooling, and only a small part of the cold air is used for dehumidification. This indicates that the ambient humidity is low and no condensation will be generated at the air outlet. At this time, all air outlets can be kept open without switching the air outlets.

[0095] If t is greater than the set time t1, it means that the cooling speed is slow. At this time, most of the air needs to be used for dehumidification, which reflects the high ambient humidity. Condensation is easy to form at the air outlet. In this case, the cooling time of a single air outlet can be reduced by switching the air outlet.

[0096] Therefore, if t≤t1, then open all the baffles so that all the air outlets can blow air at the same time;

[0097] If t > t1, then close at least one air outlet and open the others. Then determine whether there is a risk of condensation at the currently opened air outlet. The step of determining whether there is a risk of condensation at the currently opened air outlet includes:

[0098] After the air conditioner continues to run for a certain period of time, obtain the temperature T of the currently open air outlet. 出风口 And obtain the dew point temperature T of the indoor environment at this time. 露 Determine if T 出风口 ≤T 露 +T 设 T 设 ≥0.

[0099] When the air conditioner runs for t m Then, detect the temperature of the currently open air outlet and compare it with the dew point temperature T of the indoor environment. 露 The comparison is based on the principle that if the temperature of the currently opened air outlet is lower than the dew point temperature of the indoor environment, it means that condensation will soon appear at the currently opened air outlet, and it can be predicted in advance whether the air outlet needs to be switched.

[0100] The formula for judgment is T. 出风口 ≤T 露 +T 设 T 设 ≥0, at which point the air outlet temperature can be switched in advance before condensation occurs. For example, if T 露 At 20℃, T 设 The temperature is 1℃. When the temperature at the air outlet reaches 21℃, the air outlet should be switched in advance. If the air outlet is switched only when the temperature at the air outlet reaches 20℃, condensation will occur, posing a risk of condensation.

[0101] Therefore, if T 出风口 ≤T 露 +T 设 T 设 If T ≥ 0, then switch the air outlet, closing the currently open air outlet and opening at least one currently closed air outlet; if T 出风口 >T 露 +T 设 T 设If the value is ≥0, the air outlet will not be switched. At this time, there is no risk of condensation at the currently opened air outlet, and step S1 will be executed.

[0102] In step S2, after switching the air outlet, the step of determining whether there is a risk of condensation at the currently opened air outlet is repeated.

[0103] The calculation method for the indoor dew point mentioned above can be obtained by looking up a table, as follows:

[0104]

[0105]

[0106] Note: The ambient temperature (Ta) for cold insulation and anti-condensation in the table is the outdoor (dry bulb) temperature of the air conditioner in summer;

[0107] The relative humidity ψ is taken as the average relative humidity of the hottest month.

[0108] The minimum switching time between baffles is 1 hour by default, but this time can be adjusted manually.

[0109] By detecting indoor ambient temperature, temperature drop time, and air outlet temperature, the air outlet pattern is controlled, with air outlets alternating between upper and lower sections to reduce the cooling time of individual air outlets and prevent condensation.

[0110] Example 6

[0111] Based on Example 5, this example discloses a control method for preventing condensation in air conditioners. This control method is performed when the air conditioner is turned on for cooling or dehumidification.

[0112] Since the problem of prolonged exposure to cold air at the air outlet only occurs when the air conditioner is turned on for cooling or dehumidification, resulting in condensation at the air outlet, the air conditioner anti-condensation control method described in Example 5 should be implemented only when the air conditioner is turned on for cooling or dehumidification.

[0113] Example 7

[0114] Since closing some air outlets will reduce the airflow efficiency of the air conditioner, in order to ensure the airflow effect, based on Example 5, this embodiment discloses that in step S1, when at least one air outlet is closed, the fan speed 2 is increased and / or the compressor frequency is increased.

[0115] With fewer air outlets, the actual air volume will be reduced. To ensure the air conditioner's cooling capacity and dehumidification effect, the fan speed 2 is increased and the compressor frequency is raised. This ensures that the air conditioner can quickly cool or dehumidify even when operating under the anti-condensation logic, maintains the outlet temperature, meets comfort requirements, and improves the user experience.

[0116] After the air outlet is closed, the indoor unit speed and compressor frequency are set to increase by default. Users can also manually set the speed and compressor frequency to remain the same or decrease them. In this case, the outlet air temperature will be higher, allowing for a longer switching interval between the baffles, reducing energy consumption, but decreasing cooling and dehumidification performance. Users can choose according to their needs.

[0117] In practical applications, the anti-condensation control method is enabled by default, and users can manually turn it off or on as needed.

[0118] Example 8

[0119] Please see Figures 1-5 Based on Example 5, this example discloses a control method for preventing condensation in air conditioning. There are two air outlets. The first air outlet 4 is above the cross-section of the air duct 1 and is marked as the upper air outlet. The second air outlet 5 is below the cross-section of the air duct 1 and is marked as the second air outlet.

[0120] When the air conditioner is in cooling or dehumidifying mode, the current indoor ambient temperature is detected, and the time t for the indoor ambient temperature to drop by 3℃ is calculated. Depending on the air conditioner fan speed setting, different set values ​​t1 are applied. When t ≤ t1, it indicates that most of the air conditioner's cooling capacity is used for cooling, and a small portion for dehumidification. At this time, the ambient humidity is low, and condensation will not occur at the air conditioner outlet. In this case, the first baffles 61 and 62 corresponding to the first air outlet 4 and the second air outlet 5 are fully open, and the airflow is directed upwards and downwards. When t > t1, it proves that condensation is likely to occur at the air outlet under this condition. In this case, the second baffle 62 of the second air outlet 5 is closed, and the first baffle 61 of the first air outlet 4 is open. Currently, the air conditioner only outputs air through the first air outlet 4. After the air conditioner has been running for 1 hour, the temperature T1 at the top air outlet is detected, and the current dew point temperature T is calculated. 露 As T1 continues to decrease, T1≤T 露 At +1℃, the first baffle 61 closes and the second baffle 62 opens. At this time, the air conditioner discharges air through the second air outlet 5. After running for another hour, the temperature T2 of the second air outlet 5 is measured and the current dew point temperature T is calculated. 露 When T2≤T 露 When the temperature reaches +1℃, switch back to top airflow and repeat the cycle. If there is no risk of condensation at the currently open air outlet, continue to monitor the indoor humidity using the steps described above.

[0121] In addition, since there is only one air outlet, the actual air volume will be reduced. To ensure the air conditioner's cooling capacity and dehumidification effect, the fan speed 2 is increased and the compressor frequency is increased. This ensures that the air conditioner can quickly cool or dehumidify even when operating under the anti-condensation logic, maintain the air outlet temperature, meet comfort requirements, and improve the user experience.
