[0056] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0057] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0058] Reference Figures 1 to 5 The present application provides a dehumidification system, which includes at least one dehumidifier 1 and a temperature control device. The system includes: at least one dehumidification wheel, a treatment adsorption air path, at least one regeneration desorption air path and a temperature control device.

[0059] Specifically, the dehumidifier 1 includes at least one dehumidification rotor, a treatment adsorption air path, and at least one regeneration desorption air path. The dehumidification rotor has a treatment area and a regeneration area. One or more dehumidification rotors are provided. The dehumidification rotors can perform adsorption dehumidification on the gas to be treated in the treatment adsorption air path. When there are multiple dehumidification rotors, the gas to be treated in the treatment adsorption air path passes through multiple dehumidification rotors in sequence for adsorption dehumidification, which can improve the adsorption and dehumidification effect of the dehumidification system. At the same time, each dehumidification rotor has a regeneration desorption air path, which can perform desorption regeneration on the dehumidification rotor, ensuring that each dehumidification rotor regeneration zone maintains a good regeneration and desorption effect.

[0060] The gas to be treated flows along the treatment adsorption air path, which passes through the treatment area of ​​the dehumidification wheel to adsorb and dehumidify the gas to be treated; the gas to be treated can be outdoor air, which can be transported indoors after adsorption and dehumidification through the treatment adsorption air path to provide dry gas for the indoor space.

[0061] The regeneration gas flows along the regeneration desorption air path, and the regeneration desorption air path passes through the regeneration zone of the dehumidification wheel, and is used to desorb and regenerate the regeneration zone of the dehumidification wheel; the regeneration gas can be indoor air, and the indoor air of the regeneration desorption air path passes through the regeneration zone of the dehumidification wheel to desorb and regenerate the regeneration zone of the dehumidification wheel, and the high-humidity air after desorption can be discharged to the outside.

[0062] Among them, the temperature regulating device is used to cool the gas to be treated and heat the regenerated gas respectively. The gas to be treated flows through the temperature regulating device and then passes through the treatment area of ​​the dehumidification wheel for dehumidification and adsorption of the gas to be treated. The gas to be treated is cooled and dehumidified by the temperature regulating device, and then the low-temperature dry air is transported to the room through adsorption and dehumidification by the dehumidification wheel. The regenerated gas flows through the temperature regulating device and then passes through the regeneration area of ​​the dehumidification wheel for regeneration and desorption of the regeneration area of ​​the dehumidification wheel. The regenerated gas in the room is heated by the temperature regulating device, and the high-temperature regenerated gas flows through the regeneration area of ​​the dehumidification wheel for desorption and regeneration of the regeneration area, and then the high-humidity regenerated gas is discharged to the outside.

[0063] Therefore, the temperature regulating device of the dehumidification system has both heating and cooling effects, and can cool and dehumidify the outdoor air. It can not only provide low-temperature air for the indoor room, but also reduce the humidity of the gas to be treated, and provide the dehumidification wheel of the dehumidifier 1 with gas with lower humidity, thereby reducing the dehumidification pressure of the dehumidification wheel treatment area. At the same time, the temperature regulating device can increase the temperature of the regenerated gas to meet the regeneration temperature of the dehumidification wheel regeneration zone, thereby realizing the desorption regeneration of the dehumidification wheel regeneration zone, so that the dehumidification wheel of the dehumidification system can perform long-term cyclic adsorption and desorption without separating the heat source or the cold source separately, thereby reducing energy consumption.

[0064] In a specific embodiment, the temperature regulating device has a cold water component and a hot water component, and the cold water component and the hot water component respectively have a flowing medium inside; as a preferred embodiment, the cold water component and / or the hot water component respectively have a circulating flowing medium inside, and the medium is preferably water, which has a large specific heat capacity and a low cost. Of course, other media in the existing technology can also be used, and this is not the only limitation here.

[0065] After the gas to be treated passes through the cold water component, the temperature of the gas to be treated decreases, and the flowing medium in the cold water component increases in temperature. The heated medium flows in the cold water component and cools down, so that the cold water component can continuously cool and dehumidify the gas to be treated.

[0066] After the regeneration gas passes through the hot water component, the regeneration gas is heated up, and the flowing medium in the hot water component is cooled down. The cooled medium flows in the hot water component and heats up, so that the hot water component can continuously heat the regeneration gas, thereby realizing continuous regeneration of the dehumidification wheel regeneration area.

[0067] In a specific embodiment, referring to Figure 1 and Figure 2 The temperature regulating device includes a chiller 2, which has an evaporation side and a condensation side; at this time, the medium flowing in the cold water component and the hot water component is water. The evaporation side of the chiller 2 is arranged corresponding to the cold water component, and is used to reduce the temperature of the medium inside the cold water component; the condensation side of the chiller 2 is arranged corresponding to the hot water component, and is used to increase the temperature of the medium inside the hot water component. As a result, the chiller 2 can provide cold water and hot water to the cold water component and the hot water component respectively, providing a cold source for cooling the gas to be treated and a heat source for heating the regenerated gas, respectively, making full use of the cold water and hot water generated by the chiller 2, which is more energy-efficient and solves the problems of small applicable air volume and limited scope of use due to one-to-one use of compressor refrigeration dehumidification.

[0068] like Figure 1 As shown, when the dehumidifier 1 of the dehumidification system has a dehumidification wheel, the cold water component on the evaporation side and the hot water component on the condensation side of the chiller 2 respectively provide corresponding cold source and heat source for the first dehumidification wheel 11 of the dehumidifier 1.

[0069] like Figure 2 As shown, in Figure 1 On the basis of the scheme shown, a dehumidifier wheel is added to the dehumidifier 1. At this time, the cold water component on the evaporation side and the hot water component on the condensation side of the chiller 2 respectively provide corresponding cold sources and heat sources for the first dehumidification wheel 11 and the second dehumidification wheel 12 of the dehumidifier 1.

[0070] In addition, if Figure 3 As shown, multiple dehumidifiers 1 can be added according to the power of the chiller 2. Each dehumidifier 1 can have one or more dehumidification wheels, so that corresponding cold sources and heat sources can be provided for more dehumidifiers 1 at the same time, making full use of the energy of the chiller 2.

[0071] In a specific embodiment, referring to Figure 4 and Figure 5The temperature regulating device includes a semiconductor module 3, which has a cold end and a hot end. The cold end of the semiconductor module 3 is arranged in correspondence with the cold water component to reduce the temperature of the medium inside the cold water component; the hot end of the semiconductor module 3 is arranged in correspondence with the hot water component to increase the temperature of the medium inside the hot water component. Thus, the semiconductor module 3 can cool down and heat up the medium flowing in the cold water component and the hot water component, respectively providing a cold source for cooling the gas to be treated and a heat source for heating the regenerated gas. The flowing medium is used to carry away the cold at the cold end and the heat at the hot end of the semiconductor module 3, thereby improving the operating efficiency of the semiconductor module 3 and saving more energy. This solves the problem of high energy consumption caused by the use of a rotary PTC electric heating method for desorption in the regeneration zone, and eliminates the need for an additional cold source to cool the fresh air, further reducing energy consumption. At the same time, it can also solve the problem of environmental pollution and noise pollution caused by the refrigerant (fluorocarbon) in the compressor refrigeration dehumidification.

[0072] like Figure 4 As shown, when the dehumidifier 1 of the dehumidification system has a dehumidification wheel, the cold water component at the cold end and the hot water component at the hot end of the semiconductor module 3 provide corresponding cold source and heat source for the first dehumidification wheel 11 of the dehumidifier 1 respectively.

[0073] like Figure 5 As shown, in Figure 4 A dehumidification wheel is added on the basis of the shown solution. At this time, the cold water component at the cold end and the hot water component at the hot end of the semiconductor module 3 respectively provide corresponding cold source and heat source for the first dehumidification wheel 11 and the second dehumidification wheel 12 of the dehumidifier 1.

[0074] In a specific embodiment, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The cold water component includes a cold water tank 4, a refrigeration circulation pump 5 and at least one first heat exchange component. The first heat exchange component is preferably a refrigeration microchannel heat exchanger, and the number of the first heat exchange components is preferably equal to that of the dehumidification wheel; the medium inside the temperature regulating device is cooled inside the cold water tank 4, and the first heat exchange component is arranged on the treatment adsorption air path on the air inlet side of the dehumidification wheel treatment area, so that the gas to be treated is cooled and dehumidified before flowing through the dehumidification wheel treatment area; wherein, the refrigeration circulation pump 5 transports the medium in the cold water tank 4 to the first heat exchange component through a pipeline, and the medium inside the first heat exchange component returns to the cold water tank 4 through the pipeline, so that the low-temperature medium in the cold water tank 4 can pass through the first heat exchange component to cool and dehumidify the gas to be treated, and at the same time, the medium after heating in the first heat exchange component flows back to the cold water tank 4 for cooling again, thereby realizing the circulating refrigeration of the medium inside the cold water component and continuously cooling and dehumidifying the gas to be treated.

[0075] The hot water component includes a hot water tank 6, a heating circulation pump 7 and at least one second heat exchange component. The second heat exchange component is preferably a heating microchannel heat exchanger, and the number of the second heat exchange components is preferably equal to that of the dehumidification wheel; the medium inside the temperature regulating device is heated inside the hot water tank 6, and the second heat exchange component is arranged on the regeneration and desorption air path on the air inlet side of the dehumidification wheel regeneration zone, so that the regeneration gas is heated before flowing through the dehumidification wheel regeneration zone, and the temperature of the regeneration gas after heating can reach the regeneration and desorption temperature of the dehumidification wheel regeneration zone; wherein, the heating circulation pump 7 transports the medium in the hot water tank 6 to the second heat exchange component through a pipeline, and the medium inside the second heat exchange component flows back to the hot water tank 6 through the pipeline, so that the high-temperature medium in the hot water tank 6 can heat the regeneration gas through the second heat exchange component, and at the same time, the medium after cooling in the second heat exchange component flows back to the hot water tank 6 for heating again, thereby realizing the circulation heating of the medium inside the hot water component and continuously heating the regeneration gas.

[0076] Reference Figure 1 and Figure 4 When the dehumidifier 1 of the dehumidification system only has the first dehumidification wheel 11, the first heat exchange component is the first cold microchannel heat exchanger 401, and the second heat exchange component is the first hot microchannel heat exchanger 601. The refrigeration circulation pump 5 transports the low-temperature medium in the cold water tank 4 to the first cold microchannel heat exchanger 401 to cool and dehumidify the gas to be treated, and the heating circulation pump 7 transports the high-temperature medium in the hot water tank 6 to the first hot microchannel heat exchanger 601 to heat the regenerated gas.

[0077] Reference Figure 2 and Figure 4 When the dehumidifier 1 of the dehumidification system has a first dehumidification rotor 11 and a second dehumidification rotor 12, the first heat exchange component includes a first cold microchannel heat exchanger 401 and a second cold microchannel heat exchanger 402, and the second heat exchange component includes a first hot microchannel heat exchanger 601 and a second hot microchannel heat exchanger 602. The refrigeration circulation pump 5 transports the low-temperature medium in the cold water tank 4 to the first cold microchannel heat exchanger 401 and the second cold microchannel heat exchanger 402, and sequentially enters the treatment area of ​​the first dehumidification rotor 11 and the second dehumidification rotor 12. The gas to be treated on the side is cooled and dehumidified. The use of a two-stage wheel for dehumidification can improve the efficiency of the wheel dehumidification, so that the gas discharged from the adsorption air path is drier and meets the humidity requirements of the room; the heating circulation pump 7 transports the high-temperature medium in the hot water tank 6 to the first hot microchannel heat exchanger 601 and the second hot microchannel heat exchanger 602, and heats the regeneration gas in the regeneration and desorption air paths of the first dehumidification wheel 11 and the second dehumidification wheel 12 respectively, so that both dehumidification wheels have better regeneration and desorption effects.

[0078] It should be noted that if Figure 1 、 Figure 2 and Figure 3In the equipment used in the temperature regulating device, the chiller 2 is used as the cold source and heat source. When the medium inside the cold water tank 4 and the hot water tank 6 is water, the cold water tank 4 and the hot water tank 6 can be directly connected to the evaporation side and the condensation side of the chiller 2, so that the chiller 2 can use the cold water tank 4 and the hot water tank 6 to produce cold water and hot water, that is, the chiller 2 directly produces cold water and hot water to cool and dehumidify the to-be-treated gas in the adsorption air path and to heat the regenerated gas in the regeneration desorption air path. Compared with the indirect heat conduction between the cold water tank 4 and the hot water tank 6 and the chiller 2, the energy utilization efficiency of the chiller 2 can be improved, and more energy-saving.
