The humidifying module is in a wet film humidifying mode, and after humidifying water wets the wet film, the wet film is blown by fresh air to be taken away, so that the humidifying purpose is realized.
Further, in the constant temperature and humidity mode, since the humidification process is isenthalpic humidification and the temperature is reduced, in order to ensure the supply air temperature, the first heat pump system and the second heat pump system need to be started for heating operation, and when humidification is performed, the humidification parameters of the humidification module can be determined according to the humidity difference between the current ambient humidity and the set humidity, and finally the operation frequency of the first heat pump system and/or the second heat pump system is determined based on the humidification parameters, so that the normal operation of the constant humidity and constant temperature mode is ensured.

It should be appreciated that if the current ambient temperature is less than the first temperature difference threshold, then there is a warm demand, and if the current ambient temperature is greater than the second temperature difference threshold, then there is a cool demand. In this embodiment, the first temperature difference threshold and the second temperature difference threshold may be set correspondingly according to actual requirements, which is not limited in this embodiment.
Further, the step S20 in this embodiment further includes:
Step S203: and calculating a humidity difference value between the current environment humidity and the set humidity.

In a specific implementation, after the humidity difference is calculated, the humidity difference is compared with a preset humidity difference threshold, and if the humidity difference is smaller than the preset humidity difference threshold, it is indicated that the indoor humidity is lower at this time, and in this case, it is determined that the humidification requirement exists at this time. Otherwise, if the humidity difference is greater than or equal to the preset humidity difference threshold, then a dehumidification demand is deemed to exist.
According to the embodiment, whether the constant temperature requirement and the humidification requirement exist or not is determined through the temperature difference value between the current environment temperature and the set temperature and the humidity difference value between the current environment humidity and the set humidity, and the temperature and humidity requirements of a user can be accurately obtained.

Specifically, if the temperature difference is greater than or equal to the second temperature difference threshold and the humidity difference is less than the preset humidity difference threshold, this indicates that the indoor temperature is higher at this time, but the humidity is lower, in this case, the fresh air dehumidifier is controlled to continue to operate in the humidification mode, that is, the fresh air dehumidifier is controlled to operate in humidification mode through the humidification module, and the constant temperature mode is exited, that is, the fresh air dehumidifier stops heating operation, and the temperature is reduced in the humidification process, so that the higher indoor temperature can be reduced while the humidification is performed by utilizing the characteristic. Further, if the temperature difference value is greater than the first temperature difference threshold value and the temperature difference value is less than the second temperature difference threshold value, it is indicated that the indoor temperature meets the user comfort requirement at this time, and meanwhile, the indoor humidity is higher, in this case, the humidification module can be used for controlling the fresh air dehumidifier to stop the humidification operation, so that the indoor humidity is reduced, and meanwhile, the indoor temperature is required to be ensured to be constant at this time, and the fresh air dehumidifier is controlled to stop the heating operation under the condition of not humidifying, so that the indoor temperature is not reduced.
According to the embodiment, the current environment temperature and the current environment humidity are detected in real time, and meanwhile, the running mode of the fresh air dehumidifier is correspondingly adjusted according to the changes of the current environment temperature and the current environment humidity, so that the comfort of a user is improved.
