For ease of understanding, only the portions of the first gas passage 1 and the second gas passage 2 located within the total heat exchanger 12 are shown in fig. 1 to 2.
The dehumidification module 13 and the spray humidification module 14 can be selectively opened or closed according to seasons or outdoor air humidity, and when the outdoor air humidity is high in summer, the dehumidification module 13 is opened and the spray humidification module 14 is closed to control the humidity; when the outdoor air humidity is low in winter, humidity control is performed by turning off the dehumidification module 13 and turning on the spray humidification module 14.
In the present embodiment, the dehumidification module 13 is a condensation dehumidification module, which includes an evaporator 131, a condenser 132, and a compressor 133; the condensation dehumidification is to cool the air to make the temperature lower than the dew point temperature, and separate out water vapor in the air, wherein the models of the evaporator 131, the condenser 132 and the compressor 133 can be adaptively selected by staff according to actual working needs, and details are not repeated here.
The spray humidification module 14 includes a plurality of liquid spray pipes which are communicated with an external water pipe, and achieves the effect of air humidification by spraying fine liquid drops.

And the outdoor fresh air humidity is processed to the constant humidity line of the indoor design working point, and meanwhile, the temperature is reduced to be lower than the indoor design temperature, so that the design requirement is met. The heat and humidity exchange recovered by the total heat exchanger obviously reduces the dehumidifying amount of the solution, reduces the circulating amount of the solution and the cold (hot) heat consumption of regeneration, and saves energy.
