Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as a method, apparatus, air conditioner, and storage medium for constant temperature dehumidification. Background Technology

[0002] When an air conditioner operates in dehumidification mode, the temperature of humid air drops significantly after passing through the evaporator, causing the air humidity to become supersaturated. Excess moisture condenses as condensate on the evaporator fins, thus dehumidifying the air. However, this inevitably leads to a drop in indoor temperature. To avoid excessively low indoor temperatures affecting user experience, current technology typically uses an electric heater to reheat the air after dehumidification by the evaporator, achieving a constant temperature dehumidification effect.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Because moisture in the air condenses not only on the evaporator but also on the electric heater, the condensate on the heater surface boils and generates noise during the heating process.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method, apparatus, air conditioner, and storage medium for constant temperature dehumidification, which can reduce noise during the process of controlling the heating of an electric heater.

[0008] In some embodiments, the method for constant temperature dehumidification includes: determining whether the indoor ambient temperature drops after the air conditioner has been running for a set time; acquiring the indoor ambient humidity when the indoor ambient temperature drops; determining that the heating mode corresponding to the indoor ambient humidity is staged start-up heating when the indoor ambient humidity is greater than a preset humidity; the staged start-up heating is used to characterize controlling the electric heater to run for a second time period at intervals of a first time period until the number of times the electric heater runs is equal to a preset number, and controlling the electric heater to be continuously running; and controlling the electric heater to heat the air dehumidified by the evaporator according to the heating mode.

[0009] In some embodiments, before acquiring indoor ambient humidity, the method further includes: determining whether the indoor ambient temperature is less than a first preset threshold; and acquiring indoor ambient humidity if the indoor ambient temperature is less than the first preset threshold.

[0010] In some embodiments, before obtaining the indoor ambient temperature, the method further includes: determining whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold; and if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold, obtaining the indoor ambient humidity.

[0011] In some embodiments, after controlling the electric heater to run for a second time period at intervals of a first time period, the method further includes: performing a correction operation on the first time period using a preset threshold.

[0012] In some embodiments, the device for constant temperature dehumidification includes: a judgment module configured to determine whether the indoor ambient temperature drops after the air conditioner has been running for a set time; an acquisition module configured to acquire the indoor ambient humidity when the indoor ambient temperature drops; a determination module configured to determine that the heating mode corresponding to the indoor ambient humidity is staged start-up heating when the indoor ambient humidity is greater than a preset humidity; the staged start-up heating is used to characterize controlling the electric heater to run for a second time period at intervals of a first time period until the number of times the electric heater runs is equal to a preset number, and controlling the electric heater to be continuously running; and a control module configured to control the electric heater to heat the air dehumidified by the evaporator according to the heating mode.

[0013] In some embodiments, the determining module is further configured to determine whether the indoor ambient temperature is less than a first preset threshold; the acquiring module is further configured to acquire the indoor ambient humidity when the indoor ambient temperature is less than the first preset threshold.

[0014] In some embodiments, the determining module is further configured to determine whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold; the acquiring module is further configured to acquire the indoor ambient humidity if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold.

[0015] In some embodiments, after controlling the electric heater to run for a second time period at intervals of a first time period, the method further includes: performing a correction operation on the first time period using a preset threshold.

[0016] In some embodiments, the air conditioner includes a processor and a memory storing program instructions, the processor being configured to execute the above-described method for constant temperature dehumidification when the program instructions are executed.

[0017] In some embodiments, the storage medium stores program instructions that, when executed, perform the above-described method for constant temperature dehumidification.

[0018] The method, apparatus, air conditioner, and storage medium for constant temperature dehumidification provided in this disclosure can achieve the following technical effects: Since the air conditioner will cause a drop in indoor temperature regardless of whether it operates in cooling or dehumidification mode, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode by judging whether the indoor ambient temperature has dropped after the air conditioner has been running for a set time. Furthermore, when the indoor ambient humidity is greater than a preset humidity, the heating method corresponding to the indoor ambient humidity is determined to be staged start-up heating. Since an indoor ambient humidity greater than the preset humidity indicates high indoor humidity, resulting in a large amount of condensation on the surface of the electric heater, it is necessary to control the electric heater to heat the air after dehumidification by the evaporator using a staged start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation.

[0033] Combination Figure 1 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0034] Step S101: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0035] Step S102: When the indoor ambient temperature drops, the air conditioner obtains the indoor ambient humidity.

[0036] In step S103, when the indoor ambient humidity is greater than the preset humidity, the air conditioner determines the heating mode corresponding to the indoor ambient humidity as phased start heating; phased start heating is used to characterize the control of the electric heater to run for a second time period at intervals of the first time period until the number of times the electric heater runs is equal to the preset number, and the control of the electric heater to be continuously in the running state.

[0037] In step S104, the air conditioner controls the electric heater to heat the air after it has been dehumidified by the evaporator, according to the heating method.

[0038] The air conditioning method provided in this disclosure causes a drop in indoor temperature regardless of whether the air conditioner operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature drops after a set operating time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, if the indoor humidity is higher than a preset humidity level, the heating method corresponding to that humidity level is determined to be phased start-up heating. Since a higher indoor humidity level indicates higher humidity, this results in more condensation on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air dehumidified by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation.

[0039] Furthermore, after the air conditioner obtains the indoor ambient humidity, it also includes: when the indoor ambient humidity is less than or equal to the preset humidity, the air conditioner determines the heating mode corresponding to the indoor ambient humidity as continuous start-up heating. Continuous start-up heating is used to characterize the period from when the electric heater is started until the air conditioner stops running.

[0040] Optionally, before obtaining the indoor ambient humidity, the method further includes: determining whether the indoor ambient temperature is lower than a first set threshold, and obtaining the indoor ambient humidity if the indoor ambient temperature is lower than the first set threshold. Since the electric heater is close to the evaporator, the heat generated by the electric heater will inevitably be transferred to the evaporator after it is turned on, potentially causing the evaporator temperature to exceed the dew point temperature. This, in turn, affects the dehumidification effect of the air conditioner. To reduce the impact of the electric heater on the dehumidification effect, this embodiment of the present disclosure, after the air conditioner has been running for a set time, first determines whether the indoor ambient temperature has dropped below the first set threshold, and only when the indoor ambient temperature has dropped below the first set threshold is the electric heater controlled to heat according to the indoor ambient humidity. Since the indoor ambient temperature has already dropped to the first set threshold at this time, that is, the evaporator temperature has dropped sufficiently low, even if the heat generated by the electric heater is transferred to the evaporator, it will not cause the evaporator temperature to exceed the dew point temperature, thereby reducing the impact of electric heating on the dehumidification effect.

[0041] Combination Figure 2 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0042] Step S201: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0043] In step S202, when the indoor ambient temperature drops, the air conditioner determines whether the indoor ambient temperature is lower than a first set threshold.

[0044] Step S203: When the indoor ambient temperature is lower than the first set threshold, the air conditioner obtains the indoor ambient humidity.

[0045] Step S204: When the indoor ambient humidity is greater than the preset humidity, the air conditioner determines the heating mode corresponding to the indoor ambient humidity as phased start heating; phased start heating is used to characterize the control of the electric heater to run for a second time period at intervals of the first time period until the number of times the electric heater runs is equal to the preset number, and the control of the electric heater to be continuously in the running state.

[0046] In step S205, the air conditioner controls the electric heater to heat the air after it has been dehumidified by the evaporator, according to the heating method.

[0047] The air conditioning method provided in this disclosure causes a drop in indoor temperature regardless of whether the air conditioner operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature has dropped after a set air conditioning operating time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, if the indoor ambient humidity is higher than a preset humidity level, the heating method corresponding to the indoor ambient humidity is determined to be phased start-up heating. Since the indoor ambient humidity is high when it is higher than the preset humidity level, a significant amount of condensation will accumulate on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air after dehumidification by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation. Additionally, after the air conditioner has operated for a set time, it is first determined whether the indoor ambient temperature has dropped below a first set threshold. Only if the indoor ambient temperature drops below the first set threshold is the electric heater controlled to heat according to the indoor ambient humidity. Since the indoor ambient temperature has already dropped to the first set threshold, meaning the evaporator temperature has dropped low enough, the heat generated by the electric heater will not cause the evaporator temperature to exceed the dew point temperature, thus reducing the impact of electric heating on the dehumidification effect.

[0048] Optionally, before obtaining the indoor ambient temperature, the method further includes: determining whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold; and if the difference is less than the second set threshold, obtaining the indoor ambient humidity. Since the electric heater is close to the evaporator, the heat generated by the electric heater will inevitably be transferred to the evaporator after it is turned on, potentially causing the evaporator temperature to exceed the dew point temperature. This, in turn, affects the dehumidification effect of the air conditioner. To reduce the impact of the electric heater on the dehumidification effect, this embodiment of the present disclosure, after the air conditioner has been running for a set time, first determines whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold, and only if the difference is less than the second set threshold is the electric heater controlled to heat according to the indoor ambient humidity. Since the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold at this time, meaning the evaporator temperature has already dropped sufficiently, even if the heat generated by the electric heater is transferred to the evaporator, it will not cause the evaporator temperature to exceed the dew point temperature, thereby reducing the impact of electric heating on the dehumidification effect.

[0049] Combination Figure 3 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0050] Step S301: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0051] In step S302, when the indoor ambient temperature drops, the air conditioner determines whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold.

[0052] In step S303, if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold, the air conditioner obtains the indoor ambient humidity.

[0053] Step S304: When the indoor ambient humidity is greater than the preset humidity, the air conditioner determines that the heating mode corresponding to the indoor ambient humidity is staged start heating; staged start heating is used to characterize the control of the electric heater to run for a second time period at intervals of the first time period until the number of times the electric heater runs is equal to the preset number, and the control of the electric heater to be continuously in the running state.

[0054] Step S305: The air conditioner controls the electric heater to heat the air after it has been dehumidified by the evaporator according to the heating method.

[0055] The air conditioning method provided in this disclosure causes a drop in indoor temperature regardless of whether the air conditioner operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature drops after a set air conditioning operating time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, if the indoor ambient humidity is higher than a preset humidity, the heating method corresponding to the indoor ambient humidity is determined to be phased start-up heating. Since the indoor ambient humidity is high when it is higher than the preset humidity, a large amount of condensation will accumulate on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air after dehumidification by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation. Additionally, after the air conditioner has been running for a set time, it is first determined whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold. Only if the difference is less than the second set threshold is the electric heater controlled to heat according to the indoor ambient humidity. Since the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold, meaning the evaporator temperature has dropped low enough, the heat generated by the electric heater will not cause the evaporator temperature to exceed the dew point temperature, thus reducing the impact of electric heating on the dehumidification effect.

[0056] Optionally, before obtaining the indoor ambient temperature, the method further includes: determining whether the indoor ambient temperature is lower than a first set threshold; if the indoor ambient temperature is lower than the first set threshold, determining whether the difference between the indoor ambient temperature and the set ambient temperature is lower than a second set threshold; and if the difference between the indoor ambient temperature and the set ambient temperature is lower than the second set threshold, obtaining the indoor ambient humidity. By first determining whether the indoor ambient temperature is lower than the first set threshold, it is possible to determine whether the current indoor ambient temperature is low, thereby determining whether heating is needed. Then, if the indoor ambient temperature is lower than the first set threshold, determining whether the difference between the indoor ambient temperature and the set ambient temperature is lower than the second set threshold, it is possible to determine whether turning on electric heating will affect the dehumidification effect. Only if the difference between the indoor ambient temperature and the set ambient temperature is lower than the second set threshold is the indoor ambient humidity obtained to determine the heating method, thereby enabling noise-reducing heating of the dehumidified air while minimizing the impact on the dehumidification effect.

[0057] Combination Figure 4 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0058] Step S401: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0059] In step S402, when the indoor ambient temperature drops, the air conditioner determines whether the indoor ambient temperature is lower than a first set threshold.

[0060] In step S403, if the indoor ambient temperature is lower than the first set threshold, the air conditioner determines whether the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold.

[0061] In step S404, if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold, the air conditioner obtains the indoor ambient humidity.

[0062] In step S405, when the indoor ambient humidity is greater than the preset humidity, the air conditioner determines that the heating mode corresponding to the indoor ambient humidity is phased start heating; phased start heating is used to characterize the control of the electric heater to run for a second time period at intervals of the first time period until the number of times the electric heater runs is equal to the preset number, and the control of the electric heater to be continuously in the running state.

[0063] Step S406: The air conditioner controls the electric heater to heat the air after it has been dehumidified by the evaporator, according to the heating method.

[0064] The air conditioning method provided in this disclosure causes a drop in indoor temperature regardless of whether the air conditioner operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature has dropped after a set air conditioning operating time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, if the indoor ambient humidity is higher than a preset humidity level, the heating method corresponding to the indoor ambient humidity is determined to be phased start-up heating. Since the indoor ambient humidity is high when it is higher than the preset humidity level, a significant amount of condensation will accumulate on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air after dehumidification by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation. Additionally, after the air conditioner has operated for a set time, it is first determined whether the indoor ambient temperature has dropped below a first set threshold. Only if the indoor ambient temperature drops below the first set threshold is the electric heater controlled to heat according to the indoor ambient humidity. Since the indoor ambient temperature has already dropped to the first set threshold, meaning the evaporator temperature has dropped low enough, the heat generated by the electric heater will not cause the evaporator temperature to exceed the dew point temperature, thus reducing the impact of electric heating on the dehumidification effect.

[0065] The first set threshold is greater than the set ambient temperature.

[0066] Optionally, after controlling the electric heater to run for a second time period after the first time period interval, the method further includes: using a preset threshold to correct the first time period.

[0067] Furthermore, the first time period is corrected using a preset threshold, including: determining whether the number of runs is less than the difference between a preset number and 1. If the number of runs is less than the difference between the preset number and 1, the first time period is increased using the preset threshold. And / or, if the number of runs is equal to the difference between the preset number and 1, the first time period is decreased using the preset threshold. Since the temperature of the condensate on the electric heater rises during the heating process, if the first time period is short during the second time period of controlling the electric heater, the condensate temperature may drop less. This can lead to a continuous rise in condensate temperature, causing the condensate on the electric heater to boil and generate noise. To reduce the likelihood of this happening, this embodiment increases the first time period using a preset threshold when the number of runs is less than the preset number. This provides sufficient time for the condensate to cool, thereby reducing the likelihood of boiling. Additionally, even if the condensate does not boil, it will still evaporate during the heating process. That is, after reducing the preset number of heating cycles by one, the condensate on the electric heater has almost completely evaporated. Therefore, even if the first time interval is reduced using the preset threshold, and then the electric heater is controlled to heat again after the first time interval, since there is very little condensate on the electric heater at this point, it will all evaporate before boiling. Therefore, this not only avoids noise but also quickly brings the electric heater to a stable operating state.

[0068] Combination Figure 5 As shown in the figure, this disclosure provides a device 500 for constant temperature dehumidification, including: a judgment module 501, an acquisition module 502, a determination module 503, and a control module 504. The judgment module 501 is configured to determine whether the indoor ambient temperature has decreased after a set air conditioning operation time. The acquisition module 502 is configured to acquire the indoor ambient humidity when the indoor ambient temperature decreases. The determination module 503 is configured to determine that the heating method corresponding to the indoor ambient humidity is staged start-up heating when the indoor ambient humidity is greater than a preset humidity. Staged start-up heating is used to characterize controlling the electric heater to run for a second time period at first time intervals until the number of times the electric heater runs equals a preset number, thus controlling the electric heater to remain in operation. The control module 504 is configured to control the electric heater to heat the air dehumidified by the evaporator according to the heating method.

[0069] The air conditioning device provided in this embodiment causes a drop in indoor temperature regardless of whether the air conditioner operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature drops after a set operating time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, when the indoor humidity is higher than a preset humidity level, the heating method corresponding to that humidity level is determined to be phased start-up heating. Since a higher indoor humidity level indicates higher humidity, this results in more condensation on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air dehumidified by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation.

[0070] Optionally, the judgment module is further configured to judge whether the indoor ambient temperature is less than a first set threshold; the acquisition module is further configured to acquire the indoor ambient humidity when the indoor ambient temperature is less than the first set threshold.

[0071] Optionally, the judgment module is further configured to determine whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold. The acquisition module is further configured to acquire the indoor ambient humidity if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold.

[0072] Optionally, after controlling the electric heater to run for a second time period after the first time period interval, the method further includes: using a preset threshold to correct the first time period.

[0073] Combination Figure 6 As shown, this embodiment of the disclosure provides an air conditioner 600, including a processor 601 and a memory 602. Optionally, the device may further include a communication interface 603 and a bus 604. The processor 601, communication interface 603, and memory 602 can communicate with each other via the bus 604. The communication interface 603 can be used for information transmission. The processor 601 can call logical instructions in the memory 602 to execute the method for constant temperature dehumidification described in the above embodiment.

[0074] The air conditioner provided in this embodiment will cause a drop in indoor temperature regardless of whether it operates in cooling or dehumidification mode. Therefore, by determining whether the indoor ambient temperature drops after the air conditioner has been running for a set time, it is possible to determine whether the air conditioner is operating in dehumidification or cooling mode. Furthermore, if the indoor ambient humidity is higher than a preset humidity level, the heating method corresponding to that humidity level is determined to be phased start-up heating. Since a higher indoor ambient humidity level indicates higher humidity, this results in a significant amount of condensation on the surface of the electric heater. Therefore, it is necessary to control the electric heater to heat the air after dehumidification by the evaporator using a phased start-up heating method. This ensures that the condensation on the surface of the electric heater remains in a non-boiling state, thereby reducing noise caused by boiling condensation.

The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units, that is, they may be located in one place or distributed across multiple network units. Some or all of the units may be selected to implement this embodiment according to actual needs. Furthermore, the functional units in the embodiments of this disclosure may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.

[0084] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to embodiments of this disclosure. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. In some alternative implementations, the functions marked in the blocks may occur in a different order than that shown in the drawings. For example, two consecutive blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. In the descriptions corresponding to the flowcharts and block diagrams in the accompanying drawings, the operations or steps corresponding to different blocks may also occur in a different order than disclosed in the description, and sometimes there is no specific order between different operations or steps. For example, two consecutive operations or steps may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. Each block in a block diagram and / or flowchart, and combinations of blocks in a block diagram and / or flowchart, can be implemented using a dedicated hardware-based system that performs the specified function or action, or using a combination of dedicated hardware and computer instructions.
