As shown in fig. 1, the first water outlet 3b is communicated with the second water inlet 4 a; or, as shown in fig. 2, the first water inlet 3a and the second water inlet 4a are independently arranged, and the water inlet temperature of the first surface air cooler 3 is lower than the water inlet temperature of the second surface air cooler 4.
It will be appreciated that in a practical process the gas stream has achieved removal of most of the water vapour by condensation in the first surface cooler 3. Thus, the second surface cooler 4 has no longer required chilled water at a lower temperature to effect further condensation of the air stream. And in prior art, the refrigerated water that often first surface cooler 3 and second surface cooler 4 let in is the same in temperature, can make whole runner dehumidification system consume a large amount of high-grade refrigerated water like this to very big increase runner dehumidification system's system energy consumption.
And in the utility model discloses in, first delivery port 3b of first surface cooler 3 with the second water inlet 4a of second surface cooler 4 links to each other, that is to say, the play water of first surface cooler 3 is used as the intaking of second surface cooler 4. Assuming that the inlet water temperature of the first surface air cooler 3 is 7 ℃, after the air flow is condensed and dehumidified from the surface of the first surface air cooler 3, the outlet water temperature of the first surface air cooler 3 may reach 12 ℃, and the inlet water temperature of the second surface air cooler 4 is 12 ℃ because the first outlet 3b of the first surface air cooler 3 is connected with the second inlet 4a of the second surface air cooler 4. Therefore, on the premise that most of water vapor is removed by the air flow through condensation of the first surface cooler 3, the inlet water temperature of the second surface cooler 4 is relatively high, and the further condensation and dehumidification functions can be also realized. From this, the temperature difference of intaking of first surface cooler 3 and second surface cooler 4 can satisfy actual condensation needs better, has avoided the waste of refrigerated water to the system energy consumption has been reduced.
Meanwhile, the utility model discloses an in another kind of embodiment, first water inlet 3a and second water inlet 4a independent setting, and the temperature of intaking of first surface cooler 3 is less than the temperature of intaking of second surface cooler 4. The inlet water temperature gradients of the two surface coolers are adjusted according to actual needs, waste of chilled water is avoided, and accordingly energy consumption of the system is reduced.
According to the utility model discloses rotary wheel dehumidification system, because the delivery port that is located the surface cooler on upper reaches links to each other with the water inlet that is located the surface cooler on low reaches, perhaps the business turn over water of a plurality of surface coolers is independent, and the temperature of intaking that is located the surface cooler on upper reaches is less than the temperature of intaking that is located the surface cooler on low reaches, has realized providing gradient temperature's refrigerated water towards rotary wheel dehumidification system, has avoided the waste of refrigerated water to the system energy consumption has been reduced.

It can be understood that if the humidity of the airflow is too high, so that the condensation effect of the first surface cooler 3 is not enough to condense most of the water vapor, the second surface cooler 4 needs chilled water with a lower temperature to ensure the dehumidification effect of the rotary wheel dehumidification system. At this time, the opening degree of the first control valve 14 may be adjusted to be small, and the first bypass valve 12 may be opened. That is to say, the second surface air cooler 4 can not only accept the effluent of the first surface air cooler 3 at this moment, but also directly accept the chilled water with lower temperature that leads to the first water inlet 3a of the first surface air cooler 3, and the temperature of the chilled water in the second surface air cooler 4 can be reduced after the two water flows are mixed, so that the condensation effect of the second surface air cooler 4 is ensured.
In some more specific embodiments, as shown in fig. 3, the rotary wheel dehumidification system further includes a first temperature sensor 18 and a second temperature sensor 19, the first temperature sensor 18 is located downstream of the first control valve 14 and upstream of the first bypass valve 12, the first temperature sensor 18 is electrically connected to the first control valve 14, and the first control valve 14 can adjust the opening degree according to a detection result of the first temperature sensor 18. The second temperature sensor 19 is located downstream of the first bypass valve 12 and upstream of the second water inlet 4a, and the first bypass valve 12 can adjust the opening degree according to the detection result of the second temperature sensor 19. It can be connected that the existence of first temperature sensor 18 and second temperature sensor 19 can make the aperture size of first control valve 14 and first bypass valve 12 accord with actual conditions more for the refrigerated water temperature in the second surface cooler 4 accords with actual need more to the waste of refrigerated water has been avoided better, the system energy consumption is reduced.

In some embodiments, as shown in fig. 3, the desiccant rotor 1 comprises a first rotor 1a and a second rotor 1b, the heating coil 6 comprises a first coil 6a and a second coil 6b, and the regeneration fan 26 comprises a first fan 26a and a second fan 26 b; the rotary wheel dehumidification system further comprises a third surface cooler 7, and the third surface cooler 7 is provided with a third water inlet 7a and a third water outlet 7 b; wherein: the air inlet filter 2, the first surface air cooler 3, the processing area of the first rotating wheel 1a, the second surface air cooler 4, the processing area of the second rotating wheel 1b, the third surface air cooler 7 and the air supply heating coil 5 are sequentially connected in series; the first coil pipe 6a, the regeneration zone of the second runner 1b, the first fan 26a, the second coil pipe 6b, the regeneration zone of the first runner 1a and the second fan 26b are sequentially connected in series; the third water inlet 7a is connected with the second water outlet 4 b; or, the first water inlet 3a, the second water inlet 4a and the third water inlet 7a are independently arranged, the water inlet temperature of the first surface air cooler 3 is lower than that of the second surface air cooler 4, and the water inlet temperature of the second surface air cooler 4 is lower than that of the third surface air cooler 7.
It can be understood that when the humidity of the airflow is too high, two surface coolers cannot meet the dehumidification requirement, and one surface cooler can be added. In this embodiment, the third water inlet 7a is connected to the second water outlet 4b, that is, the outlet water of the first surface air cooler 3 is used as the inlet water of the second surface air cooler 4, and the inlet water of the second surface air cooler 4 is used as the inlet water of the third surface air cooler 7. From this, realized that the temperature of intaking of first surface cooler 3 is less than the temperature of intaking of second surface cooler 4, the temperature of intaking of third surface cooler 7 is less than the temperature of intaking of second surface cooler 4, satisfies actual condensation needs betterly, has avoided the waste of refrigerated water to the system energy consumption has been reduced.
