Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and specifically provides an air conditioner and an energy-saving control method for refrigeration thereof. BACKGROUND

[0002] An air conditioner is a device capable of refrigerating an environment, which can provide a cool and comfortable environment for a user in a hot summer. However, the existing air conditioner has a large power consumption when refrigerating an environment.

[0003] The existing air conditioner can refrigerate an environment when operating in a refrigeration mode and a dehumidification mode. Compared with the refrigeration mode, the air conditioner has lower energy consumption when operating in the dehumidification mode. Moreover, compared with the refrigeration mode, the refrigeration temperature can be reduced by about 2℃ to 4℃ when the air conditioner operates in the dehumidification mode.

[0004] Therefore, how to provide a comfortable environment for a user by the dehumidification mode of the air conditioner has become a technical problem to be solved in the field. SUMMARY

[0005] An object of the present application is to solve at least one of the above technical problems.

[0006] A further object of the present application is to further save energy consumption during dehumidification of the air conditioner.

[0007] To achieve the above object, the present application provides an energy-saving control method for refrigeration of an air conditioner in a first aspect, comprising:

[0008] In response to the air conditioner being turned on, a current environment humidity H1 is obtained.

[0009] It is determined whether the current environment humidity H1 is greater than a humidity threshold value.

[0010] If yes, the air conditioner is controlled to operate in a dehumidification mode.

[0011] Optionally, while the current environment humidity H1 is obtained, the energy-saving control method further comprises obtaining a current environment temperature, which is recorded as an initial environment temperature M1.

[0012] While the step of controlling the air conditioner to operate in the dehumidification mode is performed, the energy-saving control method further comprises:

[0013] A current environment temperature is obtained in real time, which is recorded as a real-time environment temperature M2.

[0014] It is determined whether a difference between the initial environment temperature M1 and the real-time environment temperature M2 is less than or equal to a temperature threshold value.

[0015] If less than or equal to, control the air conditioner to switch from the dehumidification mode to the refrigeration mode.

[0016] Optionally, after the step of controlling the air conditioner to switch from the dehumidification mode to the refrigeration mode, the power saving control method comprises:

[0017] determining whether the current environmental humidity H1 is less than or equal to the user's suitable humidity H0;

[0018] If less than or equal to, control the air conditioner to start the humidification function.

[0019] Optionally, after the step of determining whether the current environmental humidity H1 is less than or equal to the humidity threshold, the power saving control method further comprises:

[0020] If less than or equal to, control the air conditioner to run in the refrigeration mode, and / or, control the air conditioner to start the humidification function.

[0021] Optionally, the power saving control method further comprises:

[0022] in response to the air conditioner running in the dehumidification mode for a preset duration, control the air conditioner to start a vibration function to make the fins of the evaporator of the air conditioner vibrate.

[0023] Optionally, the step of controlling the air conditioner to start the vibration function comprises:

[0024] determining a vibration frequency of a vibrator of the air conditioner according to the current environmental humidity H1, the vibrator being configured to drive the fins to vibrate;

[0025] controlling the vibrator to run at the determined vibration frequency.

[0026] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current environmental humidity H1 comprises:

[0027] f = H1 x d

[0028] wherein d is a frequency base and is selected from any value in the range of 50 Hz to 1000 Hz.

[0029] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current environmental humidity H1 comprises:

[0030] finding a vibration frequency corresponding to the current environmental humidity H1 from a pre-stored current environmental humidity-vibration frequency mapping table, and determining the found vibration frequency as the vibration frequency of the vibrator.

[0031] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current ambient humidity H1 further comprises:

[0032] Obtaining the vibration noise of the air conditioner;

[0033] Determining whether the vibration noise is greater than or equal to a preset noise threshold value;

[0034] If yes, increasing or decreasing the vibration frequency of the vibrator until the vibration noise is less than the noise threshold value.

[0035] The application provides an air conditioner in a second aspect, comprising a processor and a memory, wherein the memory stores a machine executable program, and the processor can implement the power saving control method of any one of the first aspect when executing the machine executable program.

[0036] Based on the foregoing description, those skilled in the art can understand that, in the foregoing technical solutions of the application, when the air conditioner is turned on, the current ambient humidity H1 is obtained, and it is determined whether the current ambient humidity H1 is greater than the humidity threshold value, so that the air conditioner is controlled to run in the dehumidification mode when it is greater. Compared with directly running the refrigeration mode when the air conditioner is turned on, the energy consumption of the air conditioner is effectively reduced. Those skilled in the art can also understand that, since the dehumidification mode is run only when the current ambient humidity H1 is greater than the humidity threshold value, the air in the room is also effectively prevented from being too dry, thereby affecting the comfort of the user.

[0037] Further, when the air conditioner is turned on, the current ambient temperature is obtained and recorded as an initial ambient temperature M1; then during the process of running the dehumidification mode of the air conditioner, the current ambient temperature is obtained in real time and recorded as a real-time ambient temperature M2, and it is determined whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to a temperature threshold value. If yes, it indicates that the air conditioner has reached the cooling limit in the dehumidification mode, and the air conditioner is controlled to switch from the dehumidification mode to the refrigeration mode, so that the air conditioner can continue to cool the environment.

[0038] Further, when the air conditioner runs in the dehumidification mode for a preset time length, a certain amount of condensed water has been formed on the evaporator of the air conditioner. At this time, the vibration function of the air conditioner is controlled to be turned on, so that the fins of the evaporator can vibrate to promote the flow of the condensed water on the fins, thereby avoiding the condensed water from being retained on the surface of the fins due to the viscosity and tension of the condensed water, and further avoiding the condensed water from absorbing too much cold of the evaporator. At the same time, the vibrating fins can also loosen the foreign matters (such as dust, lint, dust, etc.) adhered to the fins and flow down with the condensed water, thereby avoiding the growth of bacteria on the evaporator of the air conditioner after a long time of use.

[0039] Further, in the process of vibrating the fins, the vibration noise of the air conditioner is acquired, and it is judged whether the vibration noise is greater than or equal to a preset noise threshold, so that in the case of yes, the vibration frequency of the vibrator is increased or decreased until the vibration noise is less than the noise threshold. Therefore, the present application also ensures that the vibration of the fins does not affect the life of the user, and ensures the user experience of the air conditioner.

[0040] Other benefits of the present application will be described in detail in conjunction with the drawings, so that those skilled in the art can more clearly understand the improvement purposes, features and advantages of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0051] Those skilled in the art should understand that the embodiments described below are only a part of the embodiments of the present application, and are intended to explain the technical principles of the present application, but not to limit the protection scope of the present application. Based on the embodiments provided by the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the protection scope of the present application.

[0052] It should be noted that, in the description of the present application, the terms indicating the direction or positional relationship such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0053] Further, it should be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, or can be the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0054] In addition, it should be noted that, in the description of the present application, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target (such as an evaporator, air, a condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target absorbs "cold" while releasing "heat", and releases "cold" while absorbing "heat". A certain target stores "cold" or "heat" to maintain the current temperature of the target. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target (such as an evaporator) absorbs heat while refrigerating.

[0055] Finally, it needs to be explained that in the description of the present application, each functional module can be a physical module composed of multiple structures, components or electronic elements, or a virtual module composed of multiple programs; each functional module can be a module existing independently of each other, or a module divided by a whole module according to functions. It should be understood by those skilled in the art that the constituting manner, implementation manner and positional relationship of each functional module can be changed as long as the technical solutions described in the present application can be realized, and therefore all should fall within the protection scope of the present application.

[0056] As shown in Figure 1 The air conditioner 100 (specifically, the indoor unit thereof) includes an evaporator 110 for cooling air entering the air conditioner 100 and a fan 120 for driving air to circulate between the inside and outside of the air conditioner 100, thereby achieving cooling of a room where the air conditioner 100 is located.

[0057] The air conditioner and the power-saving control method for cooling thereof in the present application will be described in detail below with reference to the accompanying drawings and in combination with specific embodiments.

[0058] As shown in Figure 2 In the first embodiment of the present application, the power-saving control method for cooling of the air conditioner includes:

[0059] In step S110, the current ambient humidity H1 is obtained in response to the air conditioner 100 being turned on.

[0060] Specifically, the current ambient humidity H1 of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by a humidity sensor arranged on the indoor unit of the air conditioner 100 at the same time when the air conditioner 100 is turned on.

[0061] In step S120, it is determined whether the current ambient humidity H1 is greater than a humidity threshold.

[0062] The humidity threshold is 30%.

[0063] In addition, those skilled in the art can set the humidity threshold to any other feasible value as needed. For example, when the air conditioner 100 detects that the user in the room is an old person, the humidity threshold is set to 40%.

[0064] In step S130, if yes, the air conditioner 100 is controlled to operate in a dehumidification mode.

[0065] Those skilled in the art can understand that if the current ambient humidity H1 is greater than the humidity threshold, it indicates that the current air humidity in the room is acceptable and at least will not cause discomfort to the user.

[0066] Optional step S140: If less than or equal to, control the air conditioner 100 to operate in cooling mode, and / or control the air conditioner 100 to turn on the humidification function.

[0067] Those skilled in the art will understand that if the current ambient humidity H1 is less than or equal to the humidity threshold, it indicates that the indoor air humidity is low and the user's body begins to feel uncomfortable, such as the user starting to experience dry nose, dry eyes, thirst, dry skin, etc.

[0068] At this time, you can turn on only the humidification function of the air conditioner 100; you can also control the air conditioner 100 to run in cooling mode; or you can turn on the humidification function of the air conditioner 100 while it is running in cooling mode; so as to avoid the air conditioner 100 from continuing to dehumidify the room, thereby avoiding the indoor air from becoming too dry.

[0069] In this invention, the indoor unit of the air conditioner 100 is equipped with a humidification module. The water source for the humidification module to humidify the air can be water added by the user or water generated during the cooling process of the air conditioner 100.

[0070] Based on the foregoing description, those skilled in the art will understand that in the first embodiment of the present invention, when the air conditioner 100 is turned on, the current ambient humidity H1 is obtained, and it is determined whether the current ambient humidity H1 is greater than a humidity threshold. If it is greater, the air conditioner 100 is controlled to operate in dehumidification mode. Compared to the air conditioner 100 directly operating in cooling mode when turned on, this effectively reduces the energy consumption of the air conditioner 100. Those skilled in the art will also understand that since the first embodiment of the present invention operates in dehumidification mode only when the current ambient humidity H1 is greater than the humidity threshold, it also effectively avoids excessively dry indoor air, thus preventing disruption to user comfort.

[0071] It should be noted that the above embodiments of the present invention are merely one basic embodiment. In other embodiments of the present invention, those skilled in the art can adjust, optimize, and configure the schemes and steps in the above embodiments as needed to achieve further technical effects. Other embodiments of the present invention, different from the above embodiments, will be described below with reference to the accompanying drawings. Of course, those skilled in the art can also appropriately modify the execution order, operating conditions, and number of steps in the embodiments described below according to actual needs. The modified embodiments will not deviate from the technical concept and / or technical principles of the present invention and should still fall within the protection scope of the present invention.

[0072] like Figure 3 As shown, in the second embodiment of the present invention, compared with the first embodiment, the energy-saving control method for air conditioning refrigeration further includes:

[0073] Step S210, in response to the air conditioner 100 being turned on, the current environment temperature is obtained and recorded as the initial environment temperature M1.

[0074] Specifically, at the same time when the air conditioner 100 is turned on, the current environment temperature of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by the temperature sensor arranged on the indoor unit of the air conditioner 100. Then the current environment temperature is recorded as the initial environment temperature M1 and stored.

[0075] Those skilled in the art can understand that step S210 can be performed at the same time as step S110.

[0076] Step S220, during the operation of the dehumidification mode of the air conditioner 100, the current environment temperature is obtained in real time and recorded as the real-time environment temperature M2.

[0077] Step S230, determine whether the difference between the initial environment temperature M1 and the real-time environment temperature M2 is less than or equal to the temperature threshold value.

[0078] Specifically, determine whether M1-M2≤temperature threshold value? That is, determine whether M2≥M1-temperature threshold value?

[0079] In this embodiment, when M1-M2≤temperature threshold value, it indicates that the air conditioner 100 has reached the cooling limit in the dehumidification mode and cannot continue to cool the environment, or the cooling rate is very small.

[0080] For this purpose, the temperature threshold value can be a specific numerical value, such as 3℃, 5℃, 7℃, etc. The temperature threshold value can also be related to M1, for example, when M1 is any value in 38℃ to 40℃, the temperature threshold value is 10℃; when M1 is any value in 35℃ to 38℃, the temperature threshold value is 7℃; when M1 is any value in 30℃ to 35℃, the temperature threshold value is 5℃; when M1 is any value in 25℃ to 30℃, the temperature threshold value is 3℃.

[0081] Step S240, if less than or equal to, control the air conditioner 100 to switch from the dehumidification mode to the refrigeration mode to ensure the refrigeration efficiency of the air conditioner 100 on the environment.

[0082] Step S250, determine whether the current environment humidity H1 is less than or equal to the user's suitable humidity H0.

[0083] In the present application, during the operation of the air conditioner 100, the current environment humidity H1 of the environment where the air conditioner 100 is located is always detected.

[0084] The suitable humidity H0 can be pre-stored on the air conditioner 100 or any feasible device such as a remote control, cloud server, or background service connected to the air conditioner 100. Furthermore, the suitable humidity H0 can be set by the user or by the manufacturer.

[0085] Furthermore, in this embodiment, the suitable humidity H0 can be a specific numerical value or a range of values.

[0086] When the suitable humidity H0 is a specific value, it can be 45%, 50%, 52%, 60%, etc.

[0087] When the suitable humidity H0 is a numerical range, it can be 40% to 50%, 45% to 60%, 45% to 50%, etc.

[0088] When the suitable humidity H0 is a numerical range, step S220 specifically involves determining whether the current ambient humidity H1 is less than or equal to the smallest value within the numerical range of the suitable humidity H0.

[0089] In step S260, if the value is less than or equal to the specified value, control the air conditioner 100 to activate the humidification function. Please refer to the previous description of step S140 for details.

[0090] Based on the foregoing description, those skilled in the art will understand that in the second embodiment of the present invention, when the air conditioner 100 is turned on, the current ambient temperature is acquired and recorded as the initial ambient temperature M1; then, during the dehumidification mode operation of the air conditioner 100, the current ambient temperature is acquired in real time and recorded as the real-time ambient temperature M2, and it is determined whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to a temperature threshold. If it is less than or equal to, it indicates that the air conditioner 100 has reached its cooling limit in the dehumidification mode, and the air conditioner 100 is controlled to switch from the dehumidification mode to the cooling mode, so that the air conditioner 100 can continue to cool the environment.

[0091] like Figure 4 As shown, in a third embodiment of the invention, the air conditioner 100 further includes a vibrator 130 configured to vibrate the fins 111 of the evaporator 110 during operation. For this purpose, the vibrator 130 can be any feasible vibration device, such as an ultrasonic generator, a rotor vibration motor, a linear vibration motor, etc. If the vibrator 130 is a linear vibration motor, the vibration direction of the linear vibration motor is parallel to the thickness direction of the fins 111.

[0092] In the case that each fin 111 can generate vibration, one or more vibrators 130 can be configured for the air conditioner 100 according to the needs of the skilled in the art. For example, all the fins 111 are grouped into N (natural number) groups, and one vibrator 130 is configured for each group of fins 111.

[0093] As shown in Figure 5 Compared with any of the foregoing embodiments, in the third embodiment of the present application, the power saving control method for air conditioner refrigeration further comprises: in response to the air conditioner 100 operating in the dehumidification mode for a preset time length, controlling the air conditioner 100 to start the vibration function to vibrate the fins 111 of the evaporator 110 of the air conditioner 100.

[0094] The "controlling the air conditioner 100 to start the vibration function" includes steps S310 and S320, which are specifically as follows:

[0095] Step S310: determining the vibration frequency of the vibrator 130 of the air conditioner 100 according to the current environmental humidity H1;

[0096] Step S320: controlling the vibrator 130 to operate at the determined vibration frequency.

[0097] In this embodiment, as an example one, step S310 can further include: f = H1 x d

[0098] Wherein, d is the frequency base and is selected from any value in the range of 50 Hz to 1000 Hz.

[0099] For example, the current environmental humidity H1 is 40%, and d is 200 Hz, then the vibration frequency f of the vibrator 130 is 80 Hz.

[0100] In this embodiment, as an example two, step S310 can further include: finding the vibration frequency corresponding to the current environmental humidity H1 from the pre-stored current environmental humidity-vibration frequency mapping table (as shown in Figure 5 And determining the found vibration frequency as the vibration frequency of the vibrator 130.

[0101] Wherein, the current environmental humidity-vibration frequency mapping table can be stored on the air conditioner 100 or any feasible device in communication connection with the air conditioner 100, such as a remote controller, a cloud server, a background server, etc.

[0102] Further, the mapping relationship between the current environmental humidity and the vibration frequency can be determined by observing the generation and retention of the condensate water on the fins 111 for multiple times.

[0103] For example, the current environmental humidity H1 is 43%, and the vibration frequency corresponding to the current environmental humidity H1 is found from the current environmental humidity-vibration frequency mapping table (as shown in Figure 5The vibration frequency of the vibrator 130 can be determined to be 150 Hz in the example shown in FIG. 1.

[0104] As shown in FIG. 1, the method can further comprise the following steps based on the method of example one or example two: Figure 7

[0105] In step S311, the vibration noise of the air conditioner 100 is acquired.

[0106] The vibration noise of the air conditioner 100 can be acquired by a microphone or other sound acquisition module or vibration detection module arranged on the air conditioner 100.

[0107] In step S312, it is determined whether the vibration noise is greater than or equal to a preset noise threshold value, and if so, step S312 is executed, and if not, no action is taken.

[0108] The noise threshold value can be any feasible value, such as 30 decibels, 35 decibels, 40 decibels, etc.

[0109] In step S313, if so, the vibration frequency of the vibrator 130 is increased or decreased until the vibration noise is less than the noise threshold value.

[0110] Specifically, when the vibration noise is greater than or equal to the preset noise threshold value, the vibration frequency of the vibrator 130 is first increased step by step according to a preset step size (e.g., 5 Hz, 10 Hz, 20 Hz, 50 Hz, etc.). If the vibration noise is still greater than or equal to the preset noise threshold value, the vibration frequency of the vibrator 130 is then decreased step by step according to the preset step size (e.g., 5 Hz, 10 Hz, 20 Hz, 50 Hz, etc.) until the vibration noise is less than the noise threshold value.

[0111] Alternatively, the vibration frequency of the vibrator 130 can be first decreased and then increased according to the needs of those skilled in the art when the vibration noise is greater than or equal to the preset noise threshold value.

[0112] Based on the foregoing description, those skilled in the art can understand that in the third embodiment of the present application, when the air conditioner 100 has been operated in the dehumidification mode for a preset time length, a certain amount of condensed water has been formed on the evaporator 110 of the air conditioner 100. At this time, by controlling the air conditioner 100 to turn on the vibration function, the fins 111 of the evaporator 110 can vibrate to promote the flow of the condensed water on the fins 111, thereby avoiding the condensed water from being retained on the surface of the fins 111 due to its own viscosity and tension, and further avoiding the condensed water from absorbing too much cold of the evaporator 110. Meanwhile, the vibrating fins 111 can also loosen the foreign matter (e.g., dust, lint, and dust) adhered to the fins 111 and flow down with the condensed water, thereby avoiding the evaporator 110 of the air conditioner 100 from breeding bacteria after a long time of use. ​

[0113] Further, in the process of vibrating the fins 111, by acquiring the vibration noise of the air conditioner 100, and judging whether the vibration noise is greater than or equal to the preset noise threshold, in the case of yes, the vibration frequency of the vibrator 130 is increased or decreased until the vibration noise is less than the noise threshold. Therefore, the third embodiment of the present application also ensures that the vibration of the fins 111 does not affect the user's life, ensuring the user's experience of using the air conditioner 100.

[0114] As Figure 8 shown, in the fourth embodiment of the present application, the power saving control method of air conditioner refrigeration includes:

[0115] Step S401, the air conditioner 100 is turned on.

[0116] Step S402, the current environment humidity H1 and the current environment temperature of the environment where the air conditioner 100 is located are acquired, and the current environment temperature is recorded as the initial environment temperature M1. For details, please refer to the description of steps S110 and S210 in the foregoing.

[0117] Step S403, judge whether the current environment humidity H1 is greater than the humidity threshold. For details, please refer to the description of step S120 in the foregoing. In the case of yes, step S404 is executed, and in the case of no, at least one of steps S407 and S409 is executed.

[0118] Step S404, control the air conditioner 100 to run in dehumidification mode.

[0119] Step S405, in the process of the air conditioner 100 running in dehumidification mode, the current environment temperature is acquired in real time and recorded as the real-time environment temperature M2.

[0120] Step S406, judge M2≥M1-temperature threshold?

[0121] For details of the temperature threshold, please refer to the description in step S230.

[0122] Step S407, control the air conditioner 100 to run in refrigeration mode.

[0123] Step S408, judge whether the current environment humidity H1 is less than or equal to the user's suitable humidity H0, in the case of less than or equal to, execute step S409, in the case of greater than, continue to execute step S407.
