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] Since air conditioners operate in either cooling or dehumidifying mode, the indoor temperature will drop. Only when the temperature of the evaporator coil is lower than the dew point temperature can water vapor in the air condense on the air conditioner evaporator, thereby achieving the effect of dehumidifying the indoor air.

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

[0004] However, to prevent low indoor temperatures, current technology often activates the electric heater to heat the air after the evaporator when the coil temperature is greater than or equal to the dew point temperature, thus ensuring the temperature of the air blown out by the air conditioner. Since the electric heater is close to the air conditioner coil, controlling the heater to heat will inevitably cause the coil temperature to rise. This may result in the coil temperature consistently exceeding the dew point temperature, thus failing to achieve the desired dehumidification effect.

[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.

[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] In step S102, when the indoor ambient temperature drops, the air conditioner obtains the dew point temperature and the coil temperature of the evaporator.

[0036] In step S103, when the coil temperature is lower than the dew point temperature, the air conditioning control electric heater heats the air after passing through the evaporator.

[0037] The method for constant temperature dehumidification provided in this disclosure determines whether the air conditioner is operating in dehumidification or cooling mode by judging whether the indoor ambient temperature has decreased after the air conditioner has been running for a set time. If the indoor ambient temperature decreases, the condensation point temperature and the evaporator coil temperature are obtained to determine whether the coil temperature is lower than the condensation point temperature, thereby determining whether the air conditioner has achieved a dehumidification effect. If the coil temperature is lower than the condensation point temperature, an electric heater is controlled to heat the air after passing through the evaporator, thereby achieving constant temperature dehumidification.

[0038] Optionally, no treatment is required if the coil temperature is greater than or equal to the dew point temperature.

[0039] Optionally, before acquiring the coil temperature and dew point temperature, the method further includes: determining whether the indoor ambient temperature is lower than a first set threshold; and acquiring the coil temperature and dew point temperature if the indoor ambient temperature is lower than the first set threshold. 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 required. Then, if the indoor ambient temperature is lower than the first set threshold, acquiring the coil temperature and dew point temperature allows it to determine whether the coil temperature is lower than the dew point temperature, thereby determining whether the air conditioner has achieved a dehumidification effect. Then, if the coil temperature is lower than the dew point temperature, the electric heater is controlled to heat the coil, thus achieving a constant temperature dehumidification effect.

[0040] Combination Figure 2 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0041] Step S201: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0042] 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.

[0043] In step S203, when the indoor ambient temperature is less than the first set threshold, the air conditioner obtains the coil temperature and the dew point temperature.

[0044] In step S204, when the coil temperature is lower than the dew point temperature, the air conditioning control electric heater heats the air after passing through the evaporator.

[0045] The method for constant temperature dehumidification provided in this disclosure determines whether the air conditioner is operating in dehumidification or cooling mode by judging whether the indoor ambient temperature has decreased after the air conditioner has been running for a set time. If the indoor ambient temperature decreases, it determines whether the indoor ambient temperature is lower than a first set threshold to determine if the current indoor ambient temperature is low and whether heating is necessary. Then, if the indoor ambient temperature is lower than the first set threshold, it acquires the coil temperature and dew point temperature to determine whether the coil temperature is lower than the dew point temperature, thus determining whether the air conditioner has achieved the dehumidification effect. Finally, if the coil temperature is lower than the dew point temperature, it controls the electric heater to heat the coil, thereby achieving constant temperature dehumidification.

[0046] Optionally, before acquiring the coil temperature and dew point 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; if the difference is less than the second set threshold, acquiring the coil temperature and dew point temperature. By determining whether the difference is less than the second set threshold, it can be determined whether the current indoor ambient temperature is low, thereby determining whether heating is needed. Then, if the difference is less than the second set threshold, acquiring the coil temperature and dew point temperature allows it to determine whether the coil temperature is lower than the dew point temperature, thereby determining whether the air conditioner has achieved dehumidification. If the coil temperature is lower than the dew point temperature, the electric heater is controlled to heat the coil, thus achieving constant temperature dehumidification.

[0047] Combination Figure 3 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0048] Step S301: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0049] 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.

[0050] 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 coil temperature and the dew point temperature.

[0051] In step S304, when the coil temperature is lower than the dew point temperature, the air conditioning control electric heater heats the air after passing through the evaporator.

[0052] The method for constant temperature dehumidification provided in this disclosure determines whether the air conditioner is operating in dehumidification or cooling mode by judging whether the indoor ambient temperature has decreased after the air conditioner has been running for a set time. If the indoor ambient temperature decreases, it determines whether the difference between the indoor ambient temperature and the set ambient temperature is less than a second set threshold to determine if the current indoor ambient temperature is low and whether heating is necessary. Then, if the difference between the indoor ambient temperature and the set ambient temperature is less than the second set threshold, it acquires the coil temperature and dew point temperature to determine whether the coil temperature is lower than the dew point temperature, thus determining whether the air conditioner has achieved the dehumidification effect. Finally, if the coil temperature is lower than the dew point temperature, it controls the electric heater to heat the coil, thereby achieving constant temperature dehumidification.

[0053] Optionally, before acquiring the coil temperature and dew point 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. If the difference between the indoor ambient temperature and the set ambient temperature is lower than the second set threshold, the coil temperature and dew point temperature are acquired. By first determining whether the indoor ambient temperature is lower than the first set threshold, it can be determined 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, it is determined whether the difference between the indoor ambient temperature and the set ambient temperature is lower than the second set threshold, thereby determining whether turning on the electric heater 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 coil temperature and dew point temperature acquired, thereby determining whether the air conditioner has achieved the dehumidification effect, and further determining whether to control the electric heater to heat. This allows for constant temperature dehumidification while minimizing the impact on the dehumidification effect.

[0054] The first set threshold is greater than the set ambient temperature.

[0055] Combination Figure 4 As shown, this disclosure provides a method for constant temperature dehumidification, including:

[0056] Step S401: After the air conditioner has been running for a set time, the air conditioner determines whether the indoor ambient temperature has dropped.

[0057] 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.

[0058] In step S403, if the indoor ambient temperature is less 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.

[0059] 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 acquires the coil temperature and the dew point temperature.

[0060] In step S405, when the coil temperature is lower than the dew point temperature, the air conditioning control electric heater heats the air after passing through the evaporator.

[0061] The method for constant-temperature dehumidification provided in this disclosure determines whether the air conditioner is operating in dehumidification or cooling mode by judging whether the indoor ambient temperature has decreased after the air conditioner has been running for a set time. If the indoor ambient temperature decreases, it first determines whether the indoor ambient temperature is lower than a first set threshold to determine if the current indoor ambient temperature is low and whether heating is necessary. Then, if the indoor ambient temperature is lower than the first set threshold, it determines whether the difference between the indoor ambient temperature and the set ambient temperature is lower than a second set threshold to determine whether turning on the electric heater 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 coil temperature and dew point temperature acquired to determine whether the air conditioner has achieved the dehumidification effect, and then whether to control the electric heater to heat. This achieves constant-temperature dehumidification with minimal impact on the dehumidification effect.

[0062] Optionally, controlling the electric heater to heat the air after passing through the evaporator includes: acquiring the indoor ambient humidity and determining a heating method corresponding to the indoor ambient humidity. The electric heater is then controlled to heat the air after passing through the evaporator according to the heating method. Since condensation may occur on the surface of the electric heater during dehumidification by the air conditioner, if the indoor ambient humidity is high, there will be more condensation on the surface of the electric heater. Controlling the electric heater to heat in this situation will cause the condensation on the surface of the electric heater to boil, thus generating noise. To reduce this noise, embodiments of this disclosure acquire the indoor ambient humidity and determine a heating method corresponding to the indoor ambient humidity, allowing the heating method of the electric heater to change with changes in indoor ambient humidity, thereby reducing noise.

[0063] In a first optional embodiment, determining the heating method corresponding to the indoor ambient humidity includes: when the indoor ambient humidity is greater than a preset humidity, the air conditioner determines the heating method corresponding to the indoor ambient humidity as staged start-up heating; 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 equals a preset number, controlling the electric heater to remain in operation. Since the indoor ambient humidity is high when it is greater than the preset humidity, there will be a lot of condensation on the surface of the electric heater. This embodiment of the present disclosure controls the electric heater to heat the air after it has been dehumidified by the evaporator according to the 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 the noise caused by the boiling of the condensation.

[0064] 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.

[0065] 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.

[0066] In the second optional embodiment, determining the heating method corresponding to the indoor ambient humidity includes: when the indoor ambient humidity is less than or equal to a preset humidity, the air conditioner determines the heating method corresponding to the indoor ambient humidity as continuous start-up heating, which is used to characterize the period from when the electric heater is started until the air conditioner stops operating.

[0067] Combination Figure 5 As shown in the illustration, this disclosure provides a device 500 for constant temperature dehumidification, including: a judgment module 501, an acquisition module 502, and a control module 503.

[0068] The device for constant temperature dehumidification provided in this embodiment determines 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. If the indoor ambient temperature drops, the device acquires the dew point temperature and the evaporator coil temperature to determine whether the coil temperature is lower than the dew point temperature, thereby determining whether the air conditioner has achieved a dehumidification effect. If the coil temperature is lower than the dew point temperature, the device controls an electric heater to heat the air after it has passed through the evaporator, thus achieving constant temperature dehumidification.
