This allows for more intelligent and accurate determination of refrigerant levels based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant shortage protection and false protection activation even when refrigerant is not missing, thus improving the level of intelligence and accuracy.

[0038] Optionally, the value of △T0 can be in the range of [3℃, 4℃]. Specifically, the value of △T0 can be either 3℃ or 4℃. In this way, the preset temperature difference threshold is set reasonably to avoid the system's refrigerant shortage protection being too high, while avoiding false protection due to insufficient refrigerant.

[0039] Optionally, the dehumidifier is based on △T 内管 , △T 内环 , △T 出风 Based on the preset temperature difference threshold △T0, determine whether the dehumidifier is short of refrigerant and control the dehumidifier to execute corresponding remedial strategies, including: the dehumidifier based on △T 内管 and △T 内环 Determine the difference ΔT1 between the evaporator tube temperature and the inner ring temperature. The dehumidifier is based on ΔT1. 内管 , △T 内环 , △T 出风Based on ΔT1 and the preset temperature difference threshold ΔT0, it is determined whether the dehumidifier is short of refrigerant, and the dehumidifier is controlled to execute the corresponding remedial strategy. Thus, based on the dehumidifier's start-up time t0 and the time after start-up t... s The difference ΔT1 between the inner ring temperature change and the evaporator tube temperature change is determined based on the dehumidifier's start-up time t0 and the time after start-up t... s The system determines the temperature difference between the evaporator pipe temperature change, inner ring temperature change, and outlet air temperature change, as well as the preset temperature difference threshold, based on the temperature changes of the inner ring temperature and evaporator pipe temperature. This allows for the assessment of whether the dehumidifier is experiencing refrigerant deficiency and the execution of corresponding remedial strategies. This approach facilitates a more intelligent and accurate assessment of refrigerant deficiency based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant deficiency protection and false protection mechanisms even when refrigerant is present, thus improving both the level of intelligence and accuracy.

[0040] Optionally, the dehumidifier is based on △T 内管 , △T 内环 , △T 出风 Based on ΔT1 and the preset temperature difference threshold ΔT0, determine whether the dehumidifier is short of refrigerant and control the dehumidifier to execute the corresponding remedial strategy, including: the dehumidifier based on ΔT1 and the preset temperature difference threshold ΔT0. 内管 , △T 内环 , △T 出风 The system uses ΔT1 and the preset temperature difference threshold ΔT0 to determine whether the dehumidifier is short of refrigerant, whether the evaporator tube temperature sensor is faulty, and whether the outlet air temperature sensor is faulty. Based on the refrigerant shortage, evaporator tube temperature sensor malfunction, and outlet air temperature sensor malfunction, the dehumidifier controls the operation of the compressor and fan and reports the corresponding fault codes. This is beneficial for understanding the difference between the dehumidifier's start-up time t0 and the time t after start-up. s The system determines the temperature difference and preset temperature difference threshold between the evaporator pipe temperature change value, inner ring temperature change value, and outlet air temperature change value, as well as the temperature difference between the inner ring temperature change value and the evaporator pipe temperature change value. This allows for the determination of whether the dehumidifier is lacking refrigerant, and whether the evaporator pipe temperature sensor and the outlet air temperature sensor are malfunctioning. Based on these dehumidifier malfunctions, the system can better control the operation of the compressor and fan and report corresponding fault codes. This facilitates a more intelligent and accurate determination of refrigerant deficiency based on the actual operating conditions of the dehumidifier, avoiding untimely refrigerant deficiency protection and false protection even when refrigerant is not lacking, thus improving the level of intelligence and accuracy.

[0041] Optionally, the dehumidifier is based on △T 内管 , △T 内环 , △T 出风 Using ΔT1 and the preset temperature difference threshold ΔT0, determine if the dehumidifier is lacking refrigerant, if the evaporator pipe temperature sensor is faulty, and if the outlet air temperature sensor is faulty, including: [the following information is missing from the original text and cannot be translated: ΔT1, ΔT0 ...内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 If the value is ≤△T0, the dehumidifier is confirmed to be without refrigerant, the evaporator tube temperature sensor is not malfunctioning, and the outlet air temperature sensor is not malfunctioning. Within △T... 内管 >△T0、△T 内环 ≤△T0、△T1>△T0、△T 出风 Under the condition ≤△T0, the dehumidifier confirms that the refrigerant is not lacking, the evaporator tube temperature sensor is not malfunctioning, and the outlet air temperature sensor is malfunctioning. Under △T 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 Under the condition that △T0 > 0, the dehumidifier is confirmed to have sufficient refrigerant, a faulty evaporator tube temperature sensor, and a normal outlet air temperature sensor. Thus, when △T 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 When ≤△T0, it indicates that no refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus indicating a refrigerant shortage. However, the evaporator pipe temperature sensor and the outlet air temperature sensor are not faulty. When △T 内管 >△T0、△T 内环 ≤△T0、△T1>△T0、△T 出风 When ΔT ≤ ΔT0, it indicates that refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus indicating that the refrigerant is not lacking. However, since the outlet air temperature remains basically unchanged, it is determined that the evaporator pipe temperature sensor is not faulty, but the outlet air temperature sensor is faulty. When ΔT 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 When the value is greater than △T0, it indicates that refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus indicating that the refrigerant is not lacking. However, since the evaporator pipe temperature does not change significantly, it is determined that the evaporator pipe temperature sensor is faulty, while the outlet air temperature sensor is not faulty. This allows for a more intelligent and accurate determination of refrigerant levels based on the actual operating conditions of the dehumidifier, avoiding untimely refrigerant shortage protection and preventing false protection when there is no refrigerant shortage, thereby improving the level of intelligence and accuracy.

[0042] Optionally, the dehumidifier controls the operation of the compressor and fan based on the refrigerant shortage status, the evaporator pipe temperature sensor malfunction status, and the outlet air temperature sensor malfunction status, and reports corresponding fault codes. These include: if the refrigerant shortage status is "refrigerant shortage," and the evaporator pipe temperature sensor malfunction status is "no fault," and the outlet air temperature sensor malfunction status is "no fault," the dehumidifier controls the compressor to stop running, the fan to stop running after a preset delay time threshold, and reports a refrigerant shortage fault code. If the refrigerant shortage status is "no refrigerant shortage," and the evaporator pipe temperature sensor malfunction status is "no fault," and the outlet air temperature sensor malfunction status is "malfunction," the dehumidifier controls the compressor to stop running, the fan to stop running after a preset delay time threshold, and reports an outlet air temperature sensor fault code. When the refrigerant level of the dehumidifier is not low, and the evaporator pipe temperature sensor is faulty, and the outlet air temperature sensor is not faulty, the dehumidifier will control the compressor and fan to stop running, and report a fault code from the evaporator pipe temperature sensor. Specifically, the preset delay time can be 30 seconds. The preset delay time can be adjusted according to the dehumidifier's properties, and will not be listed here. In this way, when the dehumidifier is low on refrigerant, and both the evaporator pipe temperature sensor and the outlet air temperature sensor are functioning correctly, the compressor stops running, and the fan stops running after the preset delay time threshold. This helps to remove excess heat from the dehumidifier, protects the compressor, and promptly reports the refrigerant low fault code, preventing delays in refrigerant low protection. When the dehumidifier has sufficient refrigerant, the evaporator pipe temperature sensor is functioning correctly, but the outlet air temperature sensor malfunctions, the compressor stops running, and the fan stops after a preset delay time threshold. This helps remove excess heat from the dehumidifier, protecting the compressor. Simultaneously, it promptly reports a fault code from the outlet air temperature sensor, alerting the user to the problem and preventing false protection mechanisms even when refrigerant is present. This system allows for more intelligent and accurate determination of refrigerant levels based on the dehumidifier's actual operating conditions, preventing delayed refrigerant shortage protection and false protection mechanisms even when refrigerant is present, thus improving the system's intelligence and accuracy.

More specifically, the value of T can be 300s. The value of T can be adjusted according to the dehumidifier's properties, which will not be listed here. This allows for a more precise determination of the dehumidifier's start-up time t0 and the time t after start-up within a preset cycle after each compressor start-up. s The changes in evaporator tube temperature, inner ring temperature, and outlet air temperature are measured to better determine the time between the dehumidifier's start-up time t0 and the time after start-up t1. s By analyzing the temperature changes of the evaporator tubes, inner ring, and outlet air, the system can determine whether the dehumidifier is lacking refrigerant and implement corresponding remedial measures. This allows for a more intelligent and accurate assessment of refrigerant levels based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant shortage protection and false protection activations when refrigerant is not lacking, thus improving both intelligence and accuracy.

[0044] Optionally, the dehumidifier determines the dehumidifier start-up time t0 and the time after start-up t... s The temperature change ΔT between the evaporator tubes 管温 Inner ring temperature change value ΔT 内环 , air outlet temperature change value △T 出风 This also includes: when the duration of each compressor start-up is greater than or equal to T, stopping the detection of the dehumidifier start-up time t0 and the time after start-up t. s The temperature change ΔT between the evaporator tubes 管温 Inner ring temperature change value ΔT 内环 , air outlet temperature change value △T 出风 The duration of each compressor start-up is greater than or equal to T, including: t s -t0≥T. Therefore, if the preset cycle is exceeded after each compressor start-up, the detection of the dehumidifier start-up time t0 and the time t after start-up will stop. sThe system monitors the temperature changes of the evaporator tubes, inner ring, and outlet air, thereby avoiding inaccurate detection of these three parameters. This allows for a more intelligent and accurate assessment of refrigerant levels based on the actual operation of the dehumidifier, preventing untimely refrigerant shortage protection and false protection even when refrigerant is not missing, thus improving the level of intelligence and accuracy.

[0045] Optionally, the compressor starts each time it is turned on, including when the dehumidifier is powered off and then back on and the humidification mode is activated. This allows for a more precise determination of the dehumidifier's start-up time t0 and the time elapsed after start-up within a preset period after each compressor start-up. s The changes in evaporator tube temperature, inner ring temperature, and outlet air temperature are measured to better determine the time between the dehumidifier's start-up time t0 and the time after start-up t1. s By analyzing the temperature changes of the evaporator tubes, inner ring, and outlet air, the system can determine whether the dehumidifier is lacking refrigerant and implement corresponding remedial measures. This allows for a more intelligent and accurate assessment of refrigerant levels based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant shortage protection and false protection activations when refrigerant is not lacking, thus improving both intelligence and accuracy.

[0073] S409, at △T 内管 >△T0、△T 内环 ≤△T0、△T1>△T0、△T 出风If the value is ≤△T0, the dehumidifier is confirmed to have sufficient refrigerant, the evaporator tube temperature sensor is functioning correctly, and the outlet air temperature sensor is functioning correctly.

[0074] S410, under the following conditions: refrigerant shortage in the dehumidifier is not present, evaporator tube temperature sensor malfunction is not present, and outlet air temperature sensor malfunction is present, the dehumidifier control compressor stops running, the fan stops running after a preset delay time threshold, and an outlet air temperature sensor fault code is reported.

[0075] S411, in △T 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 Under the condition of >△T0, the dehumidifier confirms that the refrigerant is not missing, the evaporator tube temperature sensor is malfunctioning, and the outlet air temperature sensor is not malfunctioning.

[0076] S412, under the following conditions: refrigerant shortage status is "no refrigerant shortage", evaporator pipe temperature sensor malfunction status is "malfunction occurred", and outlet air temperature sensor malfunction status is "no malfunction occurred", the dehumidifier control compressor stops running, the fan stops running, and an evaporator pipe temperature sensor fault code is reported.

[0077] The method for controlling a dehumidifier provided in this disclosure can better determine the dehumidifier's start-up time t0 and the time t after start-up. s The changes in evaporator tube temperature, inner ring temperature, and outlet air temperature between these values ​​are based on the dehumidifier's start-up time t0 and the time t after start-up. s The temperature change of the inner ring and the temperature change of the evaporator tubes are used to determine the difference ΔT1 between them. When ΔT... 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 When ≤△T0, it indicates that no refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus indicating a refrigerant shortage. However, the evaporator pipe temperature sensor and the outlet air temperature sensor are not faulty. Therefore, the compressor is stopped, and the fan stops operating after a preset delay time threshold. This helps remove excess heat from the dehumidifier and protects the compressor. Simultaneously, a refrigerant shortage fault code is promptly reported to prevent untimely refrigerant shortage protection. When △T... 内管 >△T0、△T 内环 ≤△T0、△T1>△T0、△T 出风When ≤△T0, it indicates that refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus determining that the refrigerant is not lacking. However, since the outlet air temperature remains basically unchanged, it is determined that the evaporator pipe temperature sensor is not faulty, but the outlet air temperature sensor is faulty. The compressor is controlled to stop running, and the fan stops running after a preset delay time threshold. This helps to remove excess heat from the dehumidifier and protect the compressor. Simultaneously, the outlet air temperature sensor fault code is promptly reported, reminding the user of the outlet air temperature detection problem and preventing false protection due to insufficient refrigerant. When △T... 内管 ≤△T0、△T 内环 ≤△T0、△T1≤△T0、△T 出风 When the value is greater than △T0, it indicates that refrigerant is participating in heat exchange in the evaporator after the compressor starts, thus confirming that the refrigerant is not lacking. However, since the evaporator pipe temperature change is not significant, it is determined that the evaporator pipe temperature sensor is faulty, while the outlet air temperature sensor is not faulty. Controlling the compressor and fan to stop operation helps protect the compressor. Simultaneously, a fault code for the evaporator pipe temperature sensor is promptly reported, alerting the user to the evaporator pipe temperature detection problem and preventing false protection even when refrigerant is not lacking. This allows for more intelligent and accurate determination of refrigerant levels based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant shortage protection and false protection even when refrigerant is not lacking, thus improving the level of intelligence and accuracy.

The determining module 501 is configured to determine the dehumidifier's start-up time t0 and the time t after start-up. s The temperature change ΔT between the evaporator tubes 内管 Inner ring temperature change value ΔT 内环 , air outlet temperature change value △T 出风 Control module 502 is configured according to △T 内管 , △T 内环 , △T 出风 Determine if the dehumidifier is short of refrigerant and control the dehumidifier to execute the corresponding remedial strategy.

[0079] Using the device for controlling a dehumidifier provided in the embodiments of this disclosure is advantageous for adjusting the dehumidifier's start-up time t0 and the time t after start-up. s By analyzing the temperature changes of the evaporator tubes, inner ring, and outlet air, the system can determine whether the dehumidifier is lacking refrigerant and implement corresponding remedial measures. This allows for a more intelligent and accurate assessment of refrigerant levels based on the actual operating conditions of the dehumidifier, preventing untimely refrigerant shortage protection and false protection activations when refrigerant is not lacking, thus improving both intelligence and accuracy.
