[0002] In air conditioning engineering, in order to realize different air treatment processes, different air heat and humidity treatment equipment needs to be used. According to different working characteristics, various heat and humidity treatment equipment is divided into two categories of direct contact type and surface type. Commonly used surface type heat and humidity treatment equipment, such as surface type air heat exchanger, can only realize isothermal and dehumidification process in air humidity treatment, and cannot humidify air.

[0006] Due to the adoption of the above technical scheme, the application has the advantages that: the humidifying device and the dehumidifying device are combined, and the heating and cooling device is combined, so that the humidifying, dehumidifying, heating and cooling processes can be realized in sections according to the needs of the air treatment process, so as to meet the air heat and humidity treatment needs under different working conditions. Compared with the traditional air treatment device, the application realizes the dehumidifying process of the air by using the solution dehumidifying principle, and the refrigeration device is only used for cooling the air after the humidifying process.
