The outdoor fresh air subjected to the first heat exchange automatically determines whether to start the first evaporator 16, the pretreatment coil 4, the second evaporator 3, the air-cooled condenser 2 and the humidifying section 24 according to seasons and outdoor climatic conditions (the functions of second heat exchange, air supply temperature adjustment, dehumidification, humidification and the like are respectively carried out), the outdoor fresh air is subjected to precooling treatment through the second evaporator 3, the heat in the air-cooled condenser 2 is discharged by utilizing discharged air, the water quantity of the water-cooled heat exchanger 6 is adjusted, the air supply temperature is adjusted, and a certain sensible heat load in the room can be borne; the treated air is sent into the room.
The first compressor 18 pushes the heat exchange liquid to flow circularly between the refrigerant channel of the first evaporator 16 and the heat medium channel of the heat exchanger 17 after passing through the circulation reversing valve 15, so as to absorb heat of the outdoor fresh air after the first heat exchange in the heat medium channel of the first evaporator 16, heat the indoor return air after the first heat exchange in the refrigerant channel of the heat exchanger 17, realize the second heat exchange, and obtain the outdoor fresh air after the second heat exchange.

The other path of cooling liquid flowing in from the water inlet 10 flows out from the water outlet 11 after passing through the pretreatment coil 4. The pretreatment coil 4 cools the outdoor fresh air subjected to the second heat exchange through the cooling liquid to a temperature close to or lower than the dew point; the outdoor fresh air is dehumidified through a heating medium channel of the second evaporator 3; then, the temperature is reduced again in the refrigerant passage of the air-cooled condenser 2, and the air is humidified after the humidification stage 24, and then flows out of the indoor air supply port 22.
According to the relevant settings, the internal circulation mode can be started, and only the indoor return air is purified, dehumidified, humidified and temperature-regulated, and then returned to the room. The air mixing mode can also be started, at the moment, the four air inlets are all opened, and part of indoor return air is mixed with purified outdoor fresh air and then is sent into the room after dehumidification, humidification and temperature adjustment.
