Fig. 2 is a schematic method diagram of an embodiment of a dehumidification control method of a dehumidification system provided by the invention.
As shown in fig. 2, according to an embodiment of the present invention, the dehumidification control method includes at least step S110 and step S120.

And step S120, controlling the dehumidification system to exit the dehumidification mode after detecting that the humidity of the air return opening of the dehumidification system or the outlet of the dehumidified container is reduced to a target humidity value.
Specifically, after the dehumidification system is started, if the current operation mode is the dehumidification mode, the fan is controlled to be started first, the electric heating device (e.g., the electric heater) is started in a delayed manner, for example, the electric heating device is controlled to be started after the fan is started for a preset time. After the electric heating device is started, hot air is blown out from the air outlet of the dehumidification system to the interior of a container (such as a shell tube) to be dehumidified to heat the interior space, air with moisture is continuously sucked from the interior of the shell tube to be dehumidified, and the air is conveyed to the air outlet again to be subjected to circulating dehumidification after sufficient heat exchange. And when the humidity of the air return opening of the dehumidification system or the outlet of the dehumidified container is detected to be reduced to a target humidity value, the dehumidification system continues to work for a period of time and then stops dehumidifying.
Optionally, the control method further includes: after entering a dehumidification mode, when detecting that the indoor environment temperature is lower than a preset temperature threshold value, entering a defrosting mode, controlling a compressor to stop working, and controlling the fan and the electric heating device to continue to operate; and after defrosting is finished, controlling the dehumidifying system to recover to the running state of the dehumidifying mode before entering the defrosting mode.
Specifically, when the system dehumidifies at an ambient temperature below a preset temperature threshold (e.g., 15 ℃), the evaporator surface may frost, which may affect the dehumidification effect, and then the defrost mode is entered. And under the defrosting mode, the compressor is controlled to stop working, the fan and the electric heating device continue to operate, and after defrosting is finished, the operation state of the dehumidification mode before defrosting is recovered.
Optionally, the control method further includes: and when the exhaust temperature of the compressor is detected to exceed a preset normal temperature range and/or the temperature and/or the humidity of an air outlet of the dehumidification system are detected to exceed a preset normal humidity range, controlling the dehumidification system to stop working and/or giving an alarm.
Specifically, a normal range of the exhaust temperature of the compressor and/or a normal range of the temperature and/or humidity of the air outlet are/is preset, when the dehumidification system runs, the exhaust temperature of the compressor and/or the temperature and/or humidity of the air outlet of the dehumidification system are/is detected in real time through a temperature and humidity detection device, and if the exhaust temperature and/or humidity of the compressor and/or the temperature and/or humidity of the air outlet of the dehumidification system exceed the normal range value, the compressor stops working and gives an alarm.
For clearly illustrating the technical solution of the present invention, the following describes an execution flow of the dehumidification control method according to an embodiment of the present invention.
Fig. 3 is a schematic method diagram of a dehumidification control method according to an embodiment of the present invention. As shown in fig. 3, the system mainly has a dehumidification mode and a defrosting mode after being turned on. The conventional working mode of the system is a dehumidification mode, a start button unit is clicked to start running, the fan is started firstly, and the compressor and the electric heating are started after time delay. After the electric heating is started, hot air is blown out from the air outlet to the shell tube to heat the inner space. And the air inlet continuously sucks air with moisture from the interior of the shell and tube to be dehumidified to perform sufficient heat exchange and then conveys the air to the air outlet for cyclic dehumidification. When the humidity of the return air inlet of the dehumidification system is reduced to a target value, the system can continue to work for a period of time and then stops dehumidifying.
When the system dehumidifies at an ambient temperature below a predetermined temperature threshold (typically below 15 ℃), the evaporator surface of the machine will frost, which may affect the dehumidification effect, and the system will enter a second mode, the defrost mode. Under the defrosting mode, the compressor of the system stops working, the fan and the electric heater continue to operate, and after defrosting is finished, the system can automatically recover the state of the dehumidifying mode before defrosting. When the system operates, the temperature and humidity detection module can detect the exhaust temperature of the compressor in real time, the temperature and humidity of the air outlet can stop working and give an alarm if the temperature and humidity of the air outlet exceed the normal range value.
In addition, when the dehumidification is greatly influenced by the wind resistance between the dehumidification system and the dehumidified container, the wind speed of the fan can be further improved, the static pressure value of the wind pipe is increased, and the dehumidification efficiency of the system is improved. For example, when the outlet air temperature is less than the preset threshold, it is determined that the wind resistance is large, and the wind speed of the fan needs to be further increased, for example, the wind speed can be further increased to the highest gear.

After the electric heating device is started, hot air is blown out from the air outlet to the interior of a container to be dehumidified (such as a shell tube) to heat the interior space, and air with moisture is continuously sucked from the interior of the shell tube to be dehumidified and is conveyed to the air outlet again to be subjected to circulating dehumidification after sufficient heat exchange. And when the humidity of the air return opening of the dehumidification system or the outlet of the container to be dehumidified is detected to be reduced to a target humidity value, the dehumidification system continues to work for a period of time and then stops dehumidifying.

Specifically, a normal range of the exhaust temperature of the compressor and/or a normal range of the temperature and/or humidity of the air outlet are/is preset, when the dehumidification system runs, the exhaust temperature of the compressor and/or the temperature and/or humidity of the air outlet are/is detected in real time through the temperature and humidity detection device, and if the exhaust temperature and/or the humidity of the air outlet exceed the normal range value, the compressor stops working and gives an alarm.
In addition, when the dehumidification is greatly affected by the wind resistance between the dehumidification system and the container to be dehumidified, the control unit 10 may further be configured to increase the wind speed of the fan, increase the static pressure value of the wind pipe, and improve the dehumidification efficiency of the system. Specifically, when the outlet air temperature is less than the preset threshold, it is determined that the wind resistance is large, and the wind speed of the fan needs to be further increased, for example, the wind speed can be further increased to the highest gear.
