The dehumidification wheel is divided into a dehumidification zone and a regeneration zone. When working, the dehumidification wheel is driven by a driving device (such as a motor), and the air passes through the dehumidification zone of the dehumidification wheel, and the moisture in the air is absorbed to obtain relatively dry air; the dehumidification wheel that absorbs moisture rotates to the regeneration zone, and the high-temperature air heated by the heater passes through the regeneration zone of the dehumidification wheel, so that the moisture in the desiccant is dissipated, and the air with moisture is discharged through the regeneration exhaust duct, and this cycle continuously dries the air.

[0003] However, existing dehumidification equipment takes up a large space, and the temperature of the desiccant rises after the heat exchange with the high-temperature air.

[0027] See also Figure 1 and Figure 2 As shown, this embodiment provides a dehumidification device, including a shell 10, a dehumidification wheel 20, a cooler 30 and a heater 40. The shell 10 has an air inlet side 11 and an air outlet side 12 relative to each other. A partition 13 is arranged in the shell 10 to divide the inner cavity of the shell 10 into a first channel 14 and a second channel 15. The first channel 14 has a first air inlet 141 and a first air outlet 142, and the second channel 15 has a second air inlet 151 and a second air outlet 152. The first air inlet 141 and the second air inlet 151 are both located on the air inlet side 11, and the first air outlet 142 and the second air outlet 152 are both located on the air outlet side 12; the dehumidification wheel 20 includes a dehumidification zone and a regeneration zone, the dehumidification zone is located in the first channel 14, and the regeneration zone is located in the second channel 15; the cooler 30 is located on the side of the dehumidification zone close to the first air outlet 142; the heater 40 is located on the side of the regeneration zone close to the second air inlet 151.

[0028] In the dehumidification equipment provided in this embodiment, the first air inlet 141 of the first channel 14 and the second air inlet 151 of the second channel 15 are both arranged on the air inlet side 11 of the shell 10, and the first air outlet 142 of the first channel 14 and the second air outlet 152 of the second channel 15 are both arranged on the air outlet side 12 of the shell 10. On the one hand, it is convenient to take in air from the same side. Compared with the method of taking in air from both sides, it is convenient to install the shell 10 on one side of the application site, which can save space; on the other hand, the cooler 30 can be arranged on the side of the dehumidification zone close to the first air outlet 142, and the heater 40 can be arranged on the side of the regeneration zone close to the second air inlet 151, ensuring that the distance between the heater 40 and the cooler 30 is relatively far, and the heater 40 and the cooler 30 are separated by a partition, thereby ensuring that the cooler 30 will not be affected by the heater 40 during the process of cooling the air passing through the dehumidification zone. The air after dehumidification and cooling is not only suitable for scenes without specific requirements on temperature, but also suitable for scenes with strict requirements on low temperature, thereby expanding the application scenes of the air after dehumidification and cooling.

[0029] Exemplarily, the application place may be a workshop, and the shell 10 may be installed on a side wall of the workshop, which is provided with two air inlets, one of which is connected to the first air inlet 141 , and the other is connected to the second air inlet 151 .

[0030] In one embodiment, the cross-section of the housing may be rectangular, and the partition 13 may be a partition fixedly connected to the inner wall of the housing 10 , so that the first channel 14 and the second channel 15 are separated and sealed.

[0031] In one embodiment, a first blower 101 is disposed in the first channel 14 , and a second blower 102 is disposed in the second channel 15 . Both the first blower 101 and the second blower 102 are located on a side of the dehumidification wheel 20 close to the air outlet side 12 .

[0032] For example, see Figure 1 As shown, the first blower 101 can be arranged on the side of the cooler 30 away from the dehumidification wheel 20, and the second blower 102 can be arranged on the side of the dehumidification wheel 20 away from the heater 40. Of course, the first blower 101 can also be arranged between the cooler 30 and the dehumidification wheel 20.

[0033] The dehumidification device provided in this embodiment, when working, outdoor fresh air can enter the first channel 14 from the first air inlet 141 along the arrow direction A, pass through the dehumidification zone of the dehumidification wheel 20, and the dehumidifying agent on the dehumidification wheel 20 adsorbs and dehumidifies the outdoor fresh air, so that the humidity of the outdoor fresh air is reduced and the temperature is increased, and then the temperature is cooled by the cooler 30 to achieve the required temperature and humidity requirements. The outdoor fresh air enters the second channel 15 from the second air inlet 151 along the arrow direction B, and the temperature of the air is increased after being heated by the heater 40. The high-temperature air passes through the regeneration zone of the dehumidification wheel 20, so that the dehumidifying agent on the dehumidification wheel 20 is desorbed and regenerated, so as to continuously dehumidify the outdoor fresh air entering the first channel 14.

[0034] It should be understood that the temperature of the desiccant will increase during the desorption and regeneration process. Therefore, when the desiccant after desorption comes into contact with the outdoor fresh air, the temperature of the outdoor fresh air will increase.

[0035] In one embodiment, see Figure 2 As shown, the dehumidification device also includes a refrigeration system, which includes an evaporator 50 and a condenser 60. The evaporator 50 is located in the first channel 14, and the condenser 60 is located in the second channel 15. The evaporator 50 and the condenser 60 are both located on the side of the dehumidification wheel 20 away from the cooler 30; along the direction from the air inlet side to the air outlet side, the heater 40 is located between the condenser 60 and the dehumidification wheel 20.

[0036] Since the heater 40 is located between the condenser 60 and the dehumidification wheel 20 , the outdoor fresh air entering the second channel 15 can be heated by the condenser 60 first and then by the heater 40 , which is beneficial to reduce the energy consumption of the heater 40 .

[0037] In this embodiment, the refrigeration system further includes a compressor 70, which is located in the second channel 15, and in the direction from the air inlet side 11 to the air outlet side 12, the compressor 70 is located between the condenser 60 and the heater 40. In this way, the condenser 60 is closer to the second air inlet 151, so as to exchange heat with the outdoor air as quickly as possible.

[0038] Exemplarily, the compressor 70 is connected between the evaporator 50 and the condenser 60 through a pipeline (not shown in the figure). The evaporator 50 and the condenser 60 are both located on the side of the dehumidification wheel 20 away from the cooler 30. This helps to shorten the length of the connecting pipeline and make the arrangement of various components more compact, which can not only further save space, but also reduce heat transfer losses and improve energy efficiency.

[0039] In addition, the compressor itself generates heat when working. Placing the compressor in the second channel is conducive to further heating the airflow by the compressor, thereby helping to further reduce the energy consumption of the heater.

[0040] Specifically, the liquid refrigerant in the evaporator 50 absorbs heat from the air, evaporates into a gaseous refrigerant, and then enters the compressor 70 to be compressed into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas dissipates heat through the condenser 60 and condenses into a high-pressure liquid. The high-pressure liquid then passes through a throttle valve (not shown in the figure) to throttle and reduce the pressure before entering the evaporator 50; the outdoor fresh air entering the first channel 14 is cooled by the evaporator 50 and then passes through the dehumidification zone of the dehumidification wheel 20; it should be understood that condensed water will be formed during the cooling process of the air passing through the evaporator, that is, the air humidity will naturally decrease during the cooling process, thereby realizing the pre-dehumidification function.

[0041] The outdoor fresh air entering the second channel 15 is heated by the condenser 60 and then by the heater 40, and then passes through the regeneration area of ​​the dehumidification wheel 20, so that the heat of the condenser 60 can be recycled and utilized, which is beneficial to reducing the energy consumption of the heater 40.

[0042] Exemplarily, the heater 40 in this embodiment can be an electric heater. Of course, in other embodiments, the heater can also be a gas heater, a graphite heater, etc.

[0043] For example, after the outdoor fresh air passes through the condenser 60, the temperature can reach above 55°C, and then it is heated to 120°C by the heater 40. The heated air passes through the regeneration zone, so that the moisture in the desiccant is vaporized and carried out of the dehumidification wheel 20, thereby achieving desorption and regeneration of the desiccant.

[0044] In one embodiment, the refrigeration system further includes a fan 90, which is located in the second channel 15, and is located between the second air inlet 151 and the condenser 60 along the direction from the air inlet side to the air outlet side. The air inlet of the fan 90 is connected to the second air inlet 151, and the air outlet of the fan 90 faces the condenser 60. By providing the fan 90, the air flow can be accelerated, the desorption regeneration efficiency can be improved, and it is ensured that the dehumidification wheel 20 can continuously and stably output dry air, thereby improving the dehumidification efficiency.

[0045] In one embodiment, the fan 90 is an EC fan. An EC fan refers to a centrifugal fan using a digital brushless DC external rotor motor or a centrifugal fan using an EC motor. EC fans can not only achieve control modes such as constant pressure, constant current, and constant power, so that the mechanical load is small and the working efficiency is high; but also can adjust the power supply output voltage in real time according to load changes, and automatically adjust the fan speed when the power supply voltage fluctuates to maintain stable operation. The use of EC fans makes the dehumidification equipment simpler, more reliable, less noisy, and longer life.

[0046] In this embodiment, the compressor 70 and the fan 90 can both adopt variable frequency stepless regulation technology to achieve free allocation of energy and air volume in a wide range.

[0047] In one embodiment, a first cooler 80 is disposed in the first channel 14 , and the first cooler 80 is located on a side of the evaporator 50 close to the first air inlet 141 .

[0048] The outdoor fresh air is first cooled by the first surface cooler 80 and then further cooled by the evaporator 50. When the temperature of the outdoor fresh air is too high, the first surface cooler 80 is used to cool the air first, which is beneficial to reduce the load of the evaporator 50.

[0049] For example, the first cooler 80 can be connected to an outdoor chilled water tank, and the cooling water in the first cooler 80 is used to connect a water-cooled air conditioning system. The water in the water-cooled air conditioning system exchanges heat with the throttled low-temperature refrigerant to form cooling water, which is supplied to the first cooler 80. For example, the first cooler 80 can reduce the temperature of the outdoor fresh air to 14°C, and then the evaporator 50 can further reduce the air temperature to 6°C.

[0050] In one embodiment, the dehumidification device further includes a box 300, the box 300 is located in the housing 10, and the evaporator 50, the condenser 60, the compressor 70, the fan 90 and the first cooler 80 are all located in the box 300. The evaporator 50, the condenser 60, the compressor 70, the fan 90 and the first cooler 80 are integrated in the box 300 to form a relatively independent overall refrigeration system, which is convenient for assembly, maintenance and replacement. For example, it can be installed in the factory before leaving the factory, the quality is more reliable, and it is also convenient for users to install.

[0051] In one embodiment, the cooler 30 is a second cooler. The second cooler can be connected to an outdoor chilled water tank. For example, the second cooler can be connected to the same outdoor chilled water tank as the first cooler 80. The second cooler is used to perform isohumidification cooling on the air dehumidified by the dehumidification wheel 20.

[0052] It should be noted that the cooler 30 may also be an evaporator or other types of heat exchangers.

[0053] In one embodiment, the first air inlet 141 is provided with a first filter 201 ; the second air inlet 151 is provided with a second filter 202 ; and the first air outlet 142 is provided with a third filter 203 .

[0054] Exemplarily, the first filter 201 and the second filter 202 can both be primary filters to perform preliminary purification on the outdoor fresh air, and the third filter 203 can be a medium-efficiency filter. The third filter 203 can be arranged on the side of the second surface cooler away from the dehumidification wheel 20, so that the air after dehumidification and cooling can be further purified to ensure the cleanliness of the air when it enters the application place.

[0055] In other embodiments, only two of the first filter 201 , the second filter 202 and the third filter 203 may be provided, or one of them may be provided selectively.

[0056] In this embodiment, see Figure 2 As shown, the first blower 101 is located between the cooler 30 and the third filter 203 .

[0057] The dehumidification equipment provided in this embodiment can reduce the total power by at least 75%, wherein the total power includes the power of the dehumidification wheel 20, the power of preheating using the condenser 60, the power of pre-dehumidification using the evaporator 50, and the power of the cold water air conditioning system.

[0058] The dehumidification equipment provided in this embodiment is used to dehumidify the outdoor fresh air, and the dew point temperature can reach -20 to -60°C, which meets the deep dehumidification standard.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
