Air carries out heat exchange process when fortune is flowed in the first air channel is as follows：Outdoor air is through the first breeze fan 11
Send into the first wind lead to, first, air by solution dehumidification unit 1 and with the low temperature and high concentration sprayed through the first spray equipment 101
Salting liquid directly contact carries out hot and humid area, and cool-down dehumidification treatment is carried out to air, obtains the relatively low dry air of relative temperature；Connect
, dry air enters adiabatic humidiflcation heat exchange unit 3, and is carried out with the running water directly contact sprayed through the 3rd spray equipment 301
Hot and humid area, the relative humidity for making air increases, temperature is further reduced, and the heat in running water absorption air simultaneously leads to heat
The first shower humidification circulation loop is crossed to pass；Then, Cryogenic air enter interior cold air water heat exchange unit 4, and with the 4th
The water system backwater flowed in heat-exchanger rig 401 carries out heat exchange, and the heat that Cryogenic air absorbs water system backwater makes it
Temperature reduction, realizes refrigeration or produces the purpose of cold water；Finally, air enter back into it is interior it is cold humidification heat exchange unit 5, and with through the 5th
The running water of the spray of heat-exchanger rig 502 carries out hot and humid area, while absorbent solution Dehumidifying element 1 is returned by the first heat exchange circulation
Road is delivered to the latent heat of phase change of interior cold humidification heat exchange unit 5, and air discharges outdoor after being changed into saturation state.
Air carries out heat exchange process when being flowed in the second air channel is as follows：Outdoor air is through the second breeze fan 12
The second air channel is sent into, first, air enters gas gas plate type heat exchanger 6；Then air enter solution regeneration unit 2 and with through second
The salting liquid of the spray of spray equipment 201 carries out hot and humid area, raises air themperature, and relative humidity increases；Last air leads to again
Cross gas gas plate type heat exchanger 6 and discharge outdoor.In the process, the air of gas gas plate type heat exchanger 6 is just entered from outdoor, can and
Enter promoting the circulation of qi gas heat exchange through by the air after solution regeneration unit 2 into gas gas plate type heat exchanger 6, make just from outdoor entrance
The air themperature of gas gas plate type heat exchanger 6 is raised, and its relative humidity is then reduced, and this can be more beneficial for continuing again for salting liquid
It is raw, so as to improve the efficiency and efficiency of overall unit.
Salting liquid dehumidifying regeneration cycle process and heat exchange process therein：
Low temperature dense saline solution is sprayed in solution dehumidification unit 1 by the first spray equipment 101, and with by therein
The air directly contact in the first air channel, now the partial pressure of water vapor in air is higher than the surface vapor pressure of salting liquid, salting liquid
The moisture in fresh air can be absorbed so as to realize the dehumidification treatments to air, dense saline solution is dense due to absorbing the moisture in air
Degree is reduced, and salting liquid falls the first liquor box 103 after spray, and flows into dilute salting liquid tank 14；Then pass through dilute salting liquid pump 8
Dilute salting liquid is pumped into the second spray equipment 201 of solution regeneration unit 2 from dilute salting liquid tank 14, in solution regeneration unit
Sprayed in 2 and carried out hot and humid area with by the air directly contact in the second air channel therein, now the water in air is steamed
Partial pressure of vapor is less than the surface vapor pressure of salting liquid, and the operative liquid water in salting liquid can become gaseous state and get into the air, so that
Salting liquid is set to regenerate dense saline solution, salting liquid can fall the second liquor box 203 after spray, and flow into dense saline solution tank 13；With
Dense saline solution is pumped into the first spray in solution dehumidification unit 1 from dense saline solution tank 13 again by dense saline solution pump 7 afterwards
Device 101 carries out spray dehumidification treatments, such iterative cycles operation.In the process, in 1 pair of the first air channel of solution dehumidification unit
Air when being dehumidified, latent heat of phase change can be discharged, latent heat of phase change gives interior cold humidification by the first heat exchange circulation circuit transmission
Heat exchange unit 5；, it is necessary to heat and absorb latent heat of phase change when solution regeneration unit 2 carries out salting liquid regeneration treatment, its heat for needing
Amount is provided by the second heat exchange circulation loop by external heat source.
Above example is only the description carried out to the preferred embodiment of the present invention, and model not is claimed to the present invention
The restriction for carrying out is enclosed, on the premise of design spirit of the present invention is not departed from, this area engineers and technicians are according to skill of the invention
