Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method and a control device of an air conditioner, and an air conditioner. Background Art

[0002] As the central air conditioning market continues to expand, multi-split systems are gaining market share. Beyond commercial applications, they are also increasingly being used in homes. However, due to their inherent complexity, multi-split systems present significant differences in installation, maintenance, and operation compared to standard single-split air conditioners.

[0003] For example, an ordinary one-to-one split air conditioner can quickly achieve cooling or heating, but a multi-split air conditioner cannot achieve rapid cooling or heating due to its large system circulation, and uncertain factors such as piping length, internal and external unit ratio, and startup load.

[0004] Specifically, although there are currently methods for implementing periodic adjustments based on the high pressure, low pressure, and exhaust of a multi-split system to gradually adjust the output of the multi-split system to meet actual load requirements, this adjustment method has at least one of the following technical issues: The adjustment time for adjusting the actual output load of the multi-split system in the related art is too long, resulting in a reduced user experience. Summary of the Invention

[0005] The present invention solves the technical problem that the adjustment time of the actual output load of a multi-split system is too long, which leads to a reduction in user experience.

[0006] To solve the above problems, the present invention provides a method for controlling an air conditioner, comprising: controlling the air conditioner to enter an operating mode; obtaining the current operating parameters of the air conditioner corresponding to the operating mode; determining whether there are stored parameters matching the current operating parameters in a preset database of the air conditioner; and if so, controlling the operation of the air conditioner according to the corresponding stored parameters.

[0007] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by extracting the storage parameters stored in the preset database, when the user subsequently turns on the air conditioner to control it to enter the operating mode, the storage parameters adapted to the current operating parameters can be directly called without the need to repeatedly adjust the air conditioner in a tedious manner, thereby shortening the time it takes for the air conditioner to adjust the output load to the target output load, thereby improving the user experience.

[0008] In one example of the present invention, the stored parameters include stored state parameters and stored output parameters, and the stored state parameters and the corresponding stored output parameters are combined into a first stored comfort parameter group; controlling the operation of the air conditioner according to the corresponding stored parameters includes: judging whether the data deviation between the current operating parameters and the corresponding stored parameters meets the deviation condition; if so, judging that the current operating parameters and the corresponding stored parameters are successfully matched; controlling the air conditioner to extract the corresponding first stored comfort parameter group for operation; wherein, the stored state parameters include the outdoor ambient temperature, the indoor ambient temperature and the total capacity of the indoor units of the air conditioner, and the stored output parameters include the set temperature and / or the set wind speed.

[0009] Compared with existing technologies, this technical solution achieves the following technical effects: Based on the actual use of the air conditioner, allowing the data deviation values ​​of each corresponding parameter mentioned above to fluctuate within a certain range can be considered to satisfy the deviation conditions. This helps to avoid excessive data deviation, which may lead to an excessive number of stored parameters in the preset database, resulting in reduced efficiency in the screening and comparison process with the current operating parameters, thereby reducing the response efficiency of the air conditioner. Simply put, the data deviation mentioned above can be controlled within a certain percentage, ensuring that the air conditioner can effectively call the stored parameters in the preset database in a short time, while also maintaining its stable output, thereby improving the user experience.

[0010] In one example of the present invention, the control of the air conditioner to extract the corresponding first stored comfort parameter group for operation includes: obtaining the first actual output parameter of the air conditioner within a first preset time; judging whether the first actual output parameter matches the stored output parameter; if not, controlling the air conditioner to adjust the operation of the air conditioner according to a first adjustment method so that the first actual output parameter meets the first target output parameter; wherein the first target output parameter is an output parameter set by the user based on the operation of the air conditioner.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it further ensures the ability of the air conditioner to adjust its output capacity in a short time, thereby avoiding the actual output parameters of the air conditioner lagging behind the target output parameters set by the user for a long time, which affects the user's experience.

[0012] In one example of the present invention, a stored output parameter that does not match the first actual output parameter is defined as a first stored output parameter; controlling the air conditioner to adjust the operation of the air conditioner according to a first adjustment method so that the first actual output parameter meets the target output parameter includes: deleting the first stored output parameter from the preset database; combining the first target output parameter and the stored state parameter into a second stored comfort parameter group, and storing the second stored comfort parameter group in the preset database.

[0013] Compared with the existing technology, the technical effects achieved by adopting this technical solution are: on the one hand, the storage parameters of the preset database are updated in a timely manner, avoiding reducing the probability of successful matching with the current operating parameters; on the other hand, by simplifying the number of storage parameters of the preset storage library, the matching rate with the current operating parameters is improved to a certain extent, avoiding the reduction in the response rate of the air conditioner due to too many storage parameters, thereby improving the efficiency of maintaining rapid cooling or heating balance in the indoor environment.

[0014] In one example of the present invention, the determining whether the data deviation between the current operating parameter and the corresponding stored parameter satisfies a deviation condition includes: if not, controlling the air conditioner to adjust the operation of the air conditioner according to the first adjustment method.

[0015] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it further ensures the ability of the air conditioner to adjust its output capacity in a short time, thereby avoiding the actual output parameters of the air conditioner lagging behind the target output parameters set by the user for a long time, which affects the user's experience.

[0016] In one embodiment of the present invention, determining whether there are stored parameters matching the current operating parameters in a preset database of the air conditioner includes: if not, controlling the air conditioner to adjust the operation of the air conditioner according to a first adjustment method.

[0017] In one example of the present invention, the control of the air conditioner to adjust the operation of the air conditioner according to the first adjustment method includes: determining the initial output parameter of the air conditioner according to the current operating parameters; adjusting the air conditioner from the initial output parameter to the second target output parameter within a second preset time according to the target air pressure set by the user; wherein, the current operating parameters include the current outdoor ambient temperature, the current indoor ambient temperature, the current total capacity of the indoor unit of the air conditioner, and the target air pressure includes a target low pressure or a target high pressure.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is to avoid directly adjusting the output load of the air conditioner to the required load size, which affects the stable operation of the air conditioner.

[0019] In one example of the present invention, controlling the air conditioner to adjust the operation of the air conditioner according to the first adjustment method includes: determining whether the operating time of the air conditioner to maintain the second target output parameter meets a third preset time; if so, combining the current operating parameters and the second target output parameters into a second stored comfort parameter group, and storing the second stored comfort parameter group in the preset database.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: using the first adjustment method to supplement the storage parameters of the preset database or correct the actual output parameters of the air conditioner so that it can match the target output parameters set by the user, so that the air conditioner can accurately maintain the heat exchange effect on the indoor environment, that is, through the synergy between the first adjustment method and the preset database, the air conditioner is able to respond to the user's command requirements in a short time, thereby improving the user experience.

[0021] On the other hand, the present invention also provides a control device for an air conditioner, comprising: a first control module, the first control module is used to control the air conditioner to enter an operating mode; an acquisition module, the acquisition module is used to obtain the current operating parameters of the air conditioner corresponding to the operating mode; a judgment module, the judgment module is used to judge whether there are storage parameters matching the current operating parameters in the preset database of the air conditioner; and a second control module, the second control module is used to control the air conditioner to adjust the operation of the air conditioner according to a first adjustment method when the judgment result of the judgment module is no.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to the control method in any of the above examples, which will not be repeated here.

[0023] In another aspect, the present invention further provides an air conditioner, comprising a controller, wherein the controller is configured to execute an executable program to implement the control method as in any of the above examples.

[0024] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0025] (1) By extracting the stored parameters in the preset database, when the user subsequently turns on the air conditioner to control it to enter the operating mode, the stored parameters adapted to the current operating parameters can be directly called without the need to repeatedly adjust the air conditioner. This can shorten the time it takes for the air conditioner to adjust the output load to the target output load, thereby improving the user experience;

[0026] (2) On the one hand, the storage parameters of the preset database are updated in a timely manner, avoiding reducing the probability of successful matching with the current operating parameters; on the other hand, by simplifying the number of storage parameters in the preset storage library, the matching rate with the current operating parameters is improved to a certain extent, avoiding the reduction of the air conditioner response rate due to too many storage parameters, thereby improving the efficiency of maintaining rapid cooling or heating balance in the indoor environment.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] See also Figure 1 , which is a flow chart of a control method for an air conditioner provided in Embodiment 1 of the present invention. The control method includes, for example:

[0034] S1, controls the air conditioner to enter the running mode.

[0035] Specifically, when the air conditioner is not started, it is usually in a standby state, and when the air conditioner receives a power-on command from a user's remote control, it enters an operating mode. The operating mode indicated here includes, for example, a cooling function or a heating function of the air conditioner.

[0036] S2, obtaining the current operating parameters of the air conditioner corresponding to the operating mode.

[0037] In a specific example, the air conditioner is a multi-split system. During the frequency-up and rapid cooling adjustment process of the multi-split system, it is often necessary to consider the installation environment factors of the multi-split system and the target parameters set by the user to perform gradual periodic adjustments to avoid blind frequency-up adjustments that may affect the normal and stable operation of the multi-split system. However, each time the user controls the multi-split system to enter the operating mode, the above-mentioned adjustment process needs to be repeated, resulting in a poor user experience. Specifically, the installation environment factors include the piping length of the multi-split system, the ratio of the indoor unit to the outdoor unit, etc. The multi-split system, for example, includes a temperature sensor for sensing the outdoor ambient temperature and the indoor ambient temperature.

[0038] S3, determining whether there are stored parameters matching the current operating parameters in the preset database of the air conditioner.

[0039] S31: If yes, the operation of the air conditioner is controlled according to the corresponding stored parameters.

[0040] Specifically, when the air conditioner receives a command sent by the user and is in stable operation, the current operating parameters of the air conditioner at this time are converted into readable data through the air conditioner's recorder and stored in a non-volatile memory when the power is off, that is, in the preset database of the present technical solution. In simple terms, the stored parameters are data parameters that keep the air conditioner in a stable operating state when receiving different commands sent by the user. Therefore, by storing the above-mentioned data parameters in the preset database so that the user can turn on the air conditioner and control it to enter the operating mode later, the stored parameters that are adapted to the current operating parameters can be directly called without the need to perform tedious adjustments on the air conditioner, thereby shortening the time it takes for the air conditioner to adjust the output load to the target output load, thereby improving the user experience.

[0041] Furthermore, in conjunction with the above, if it is determined that the air conditioner's preset database does not contain stored parameters that match the current operating parameters, there are two possible scenarios: 1. The number of stored parameters in the preset database is zero; or 2. The stored parameters in the preset database do not match the air conditioner's current operating parameters. Specifically, for example, at least one of the current operating parameters, such as the outdoor ambient temperature, indoor ambient temperature, or the target temperature in the user's command, does not match the stored parameters. Therefore, either of the above scenarios is considered a mismatch.

[0042] Preferably, the storage parameters include storage state parameters and storage output parameters, and the storage state parameters and the corresponding storage output parameters are combined into a first storage comfort parameter group; S31 specifically includes:

[0043] S311, determining whether the data deviation between the current operating parameter and the corresponding stored parameter meets the deviation condition.

[0044] S312: If yes, determine whether the current operating parameters match the corresponding storage parameters successfully.

[0045] S313: Control the air conditioner to extract the corresponding first stored comfort parameter group for operation, wherein the stored state parameters include the outdoor ambient temperature, the indoor ambient temperature, and the total capacity of the air conditioner's indoor units, and the stored output parameters include the set temperature and / or the set wind speed.

[0046] In one specific example, the current operating parameters include, for example, the current outdoor ambient temperature, the indoor ambient temperature, the target temperature, and the current total capacity of the air conditioner's indoor units. For ease of distinction, the outdoor ambient temperature in the stored state parameters can be defined as a preset outdoor ambient temperature, the indoor ambient temperature as a preset indoor ambient temperature, and the temperature used to match the target temperature in the stored state parameters as a preset temperature. Furthermore, in light of the actual use of the air conditioner, allowing the data deviation values ​​of each of the aforementioned corresponding parameters to fluctuate within a certain range can be considered to satisfy the deviation condition. This helps avoid excessive refinement of the data deviation, which could result in an excessive number of stored parameters being stored in the preset database, reducing the efficiency of the screening and comparison process using the current operating parameters, and thus reducing the response efficiency of the air conditioner.

[0047] In simple terms, the data deviation mentioned above can be controlled within a certain percentage, which can ensure that the air conditioner can effectively call the storage parameters in the preset database, while also maintaining its stable output, thereby improving the user experience.

[0048] Preferably, S313 specifically includes:

[0049] S3131, obtaining a first actual output parameter of the air conditioner within a first preset time.

[0050] S3132: Determine whether the first actual output parameter matches the stored output parameter.

[0051] If not, then control the air conditioner to adjust its operation according to a first adjustment method so that the first actual output parameter meets the first target output parameter, wherein the first target output parameter is an output parameter set by the user when the air conditioner is running.

[0052] In a specific example, when it is determined that the first actual output parameter does not match the stored output parameter, it is possible that the air conditioner has been in use for a long time, for example, the condenser of the indoor unit is dirty and blocked, so that the current first target output parameter needs to be greater than the stored output parameter stored in the preset database that matches it in order to meet the cooling or heating balance of the indoor environment.

[0053] Furthermore, if the air conditioner is still operated according to the first actual output parameter, the indoor environment will not be able to maintain a balanced cooling or heating, that is, the target temperature and / or target wind speed set by the user cannot be reached.

[0054] Preferably, the stored output parameter that does not match the first actual output parameter is defined as the first stored output parameter; S3133 specifically includes:

[0055] S3134: Delete the first stored output parameter from the preset database.

[0056] S3135: Combine the first target output parameter and the stored state parameter into a second stored comfort parameter group, and store the second stored comfort parameter group in a preset database.

[0057] In a specific example, combined with the content of the above specific example, after the air conditioner has been used for a long time, it is necessary to adjust the storage comfort parameter group stored in the preset database that no longer satisfies the combination of the storage state parameters and the storage output parameters. For example, by deleting the first storage output parameter, the first target output parameter is combined with the storage state parameter to form a second storage comfort parameter group. On the one hand, the storage parameters of the preset database are updated in a timely manner, avoiding reducing the probability of successful matching with the current operating parameters; on the other hand, by simplifying the number of storage parameters in the preset storage library, the matching rate with the current operating parameters is improved to a certain extent, avoiding the reduction in the response rate of the air conditioner due to too many storage parameters, thereby improving the efficiency of maintaining rapid cooling or heating balance of the indoor environment.

[0058] Preferably, S311 specifically includes:

[0059] S3111: If not, control the air conditioner to adjust its operation according to the first adjustment method.

[0060] Preferably, S3 specifically includes:

[0061] S32: If not, control the air conditioner to adjust the operation of the air conditioner according to the first adjustment mode.

[0062] Preferably, S32 specifically includes:

[0063] S321: Determine initial output parameters of the air conditioner according to current operating parameters.

[0064] S322: Adjust the air conditioner from an initial output parameter to a second target output parameter within a second preset time period based on a target air pressure set by the user. The current operating parameters include the current outdoor ambient temperature, the current indoor ambient temperature, and the current total capacity of the air conditioner's indoor units. The target air pressure includes a target low pressure or a target high pressure.

[0065] Preferably, S32 specifically includes:

[0066] S323, determining whether the operating time of the air conditioner maintaining the second target output parameter satisfies a third preset time.

[0067] S324: If yes, the current operating parameter and the second target output parameter are combined into a second stored comfort parameter group, and the second stored comfort parameter group is stored in a preset database.

[0068] Specifically, the first adjustment method is used to supplement the storage parameters of the preset database or correct the actual output parameters of the air conditioner so that it can match the target output parameters set by the user, so that the air conditioner can accurately maintain the heat exchange effect on the indoor environment. That is, through the synergy between the first adjustment method and the preset database, the air conditioner is able to respond to the user's command requirements in a short time, thereby improving the user experience.
