when the upper-layer solid dehumidifying module dehumidifies the cooled fresh air, the heated return air regenerates the lower-layer solid dehumidifying module; when the lower-layer solid dehumidification module dehumidifies the cooled fresh air, the heated return air regenerates the upper-layer solid dehumidification module.
Preferably, the dehumidification system according to any of the above embodiments is used to dehumidify fresh air introduced into a room.
In summary, the dehumidification system and the dehumidification method provided by the embodiment of the invention dehumidify the cooled fresh air through the solid dehumidification module, and regenerate the solid dehumidification module through the heated return air, so that the dehumidification system has good dehumidification performance and high dehumidification efficiency. On the other hand, the solid dehumidification and the refrigeration system are combined, the evaporator of the refrigeration system is used for cooling the fresh air, and the condenser is used for heating the return air, so that the temperature of the solid dehumidification module for processing the fresh air is lower, and the dehumidification performance is improved; in addition, due to the flow of the refrigerating system, the temperature of fresh air processed by the evaporator is higher, and the temperature of return air processed by the condenser is lower, so that the energy efficiency of the dehumidifying system is improved.
The person skilled in the art will readily understand that the advantageous ways described above can be freely combined, superimposed without conflict.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
