Description

Technical Field

[0001] The present invention relates to the technical field of waterless humidification, in particular to a waterless humidification device and an air conditioner. Background Art

[0002] Waterless humidification uses hygroscopic materials to absorb moisture in the air. The air absorbs moisture through the hygroscopic sector of the hygroscopic wheel. Then the heated regenerated air in the dehumidification zone of the hygroscopic wheel takes away the moisture from the hygroscopic wheel for dehumidification, and the hot and humid air is sent into the room through the fan.

[0003] In order to improve the moisture absorption efficiency of the moisture absorption wheel in the prior art, a cooling zone is set on the moisture absorption wheel, and the regenerated air is first passed through the cooling zone to cool the cooling zone to restore the water absorption performance of the moisture absorption rotor and increase the temperature of the regenerated air before heating and dehumidification.

[0004] However, after the regeneration air passes through the cooling zone, the moisture in the regeneration air is removed and the air volume of the regeneration air becomes smaller, resulting in a decrease in the humidification amount. Summary of the Invention

[0005] The problem solved by the present invention is that the moisture in the regeneration air is separated after the regeneration air passes through the cooling zone and the air volume of the regeneration air becomes smaller, thereby reducing the humidification amount.

[0006] To solve the above problems, an embodiment of the present invention provides a waterless humidification device and an air conditioner, which can improve the problem that the moisture in the regenerated air is separated after passing through the cooling zone and the air volume of the regenerated air becomes smaller, resulting in reduced humidification.

[0010] In this embodiment, the air outlet of the regeneration fan is connected to the cooling air inlet and the bypass air duct respectively, so that the regeneration fan can blow regeneration air into the cooling area and the bypass air duct at the same time, and the structure is simpler and more compact.

[0011] In an optional embodiment, the regeneration fan is installed at the cooling air inlet, and the bypass air duct is connected to the cooling air inlet, so that part of the gas flowing in from the cooling air inlet flows into the bypass air duct and the other part flows into the cooling zone.

[0012] In this embodiment, the cooling air inlet is connected to the bypass air duct, so that the regeneration air flowing in from the cooling air inlet can be supplied to the cooling zone and the bypass air duct at the same time, making the design of the flow channel simpler.

[0013] In an optional embodiment, the bypass air duct is parallel to the axis of the moisture absorption wheel. By setting the bypass air duct parallel to the axis of the moisture absorption wheel, a single blower can be used to blow air to the cooling zone and the bypass air duct, eliminating the need for additional blowing equipment for the bypass air duct, thereby further saving costs.

[0014] In an optional embodiment, the shell is enclosed on the outside of the moisture absorbing wheel, and the bypass air duct is provided at a position of the shell corresponding to the outer periphery of the cooling zone.

[0015] In this embodiment, the bypass air duct is arranged at the outer periphery corresponding to the shell and the cooling zone, so that the air blowing device can blow the regeneration air into the cooling zone and the bypass air duct at the same time.

This allows for more regenerated air to pass through the bypass duct within a limited space, thereby better compensating for air volume loss. Simultaneously, a single fan can be used to blow regenerated air into the first duct, the second duct, and the cooling zone.

[0019] In an optional embodiment, the valve body is movably mounted on the housing, and the valve body can move relative to the housing to partially block, close, or open the bypass air duct.

DETAILED DESCRIPTION

[0028] In order to improve the moisture absorption efficiency of the moisture absorption wheel in the prior art, a cooling zone is set on the moisture absorption wheel, and the regenerated air is first passed through the cooling zone to cool the cooling zone to restore the water absorption performance of the moisture absorption rotor and increase the temperature of the regenerated air before heating and dehumidification.

[0029] However, after the regeneration air passes through the cooling zone, the moisture in the regeneration air is removed and the air volume of the regeneration air becomes smaller, resulting in a decrease in the humidification amount.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 An embodiment of the present invention provides an air conditioner, comprising an indoor unit, an outdoor unit, and a waterless humidifying device 100, wherein the outdoor unit and the indoor unit are connected by a pipe. The waterless humidifying device 100 is used to humidify air inside a building or structure.

[0032] In this embodiment, the waterless humidifier 100 is installed in an outdoor unit and can deliver humidified air to a building or structure via a pipe. In other embodiments of the present application, the waterless humidifier 100 can also be installed in an indoor unit. It should be understood that this embodiment does not limit the installation of the waterless humidifier 100 in an indoor unit or an outdoor unit.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the waterless humidification device 100 includes a moisture absorption wheel 110, a housing 130, and a heating device 150. The moisture absorption wheel 110 is rotatably mounted on the housing 130. The housing 130 is provided with a partition structure 131, which divides the moisture absorption wheel 110 into an adsorption zone 111, a cooling zone 113, and a desorption zone 115. The adsorption zone 111 is used to absorb moisture from the gas flowing through it. The heating device 150 is provided in the housing 130 at a position corresponding to the desorption zone 115 and is used to heat the gas flowing through it. The housing 130 is provided with a cooling air inlet 133, a humidifying air outlet 135, and a bypass air duct 137. The cooling air inlet 133 is connected to the cooling zone 113. The cooling zone 113 and the bypass air duct 137 are both connected to the air inlet side of the heating device 150. The air outlet side of the heating device 150 is connected to the desorption zone 115, and the desorption zone 115 is connected to the humidifying air outlet 135. The regeneration gas flowing into the cooling air inlet 133 flows through the cooling zone 113, the heating device 150, and the desorption zone 115 in sequence, and is discharged from the humidifying air outlet 135. The regeneration gas flowing into the bypass air duct 137 passes through the heating device 150 and the desorption zone 115 in sequence, and is discharged from the humidifying air outlet 135. The bypass air duct 137 is provided with a valve body 170, which can control the opening of the bypass air duct 137.

[0034] The waterless humidifier 100 provided in the application is provided with a cooling air inlet 133 connected to the cooling zone 113. The regeneration air flowing into the cooling air inlet 133 sequentially flows through the cooling zone 113, the heating device 150, and the desorption zone 115, and is discharged from the humidification air outlet 135. This cools the cooling zone 113, thereby restoring the moisture absorption capacity of the moisture absorption wheel 110 and recovering heat. A bypass air duct 137 is provided in the housing 130 and is connected to the air inlet side of the heating device 150. This allows the regeneration air flowing through the bypass air duct 137 to be directly heated and dehumidified without passing through the moisture absorption wheel 110, thereby replenishing the regeneration air volume and humidity. Furthermore, a valve body 170 is provided in the bypass air duct 137. The valve body 170 can be used to control the opening of the bypass air duct 137, allowing the opening of the bypass air duct 137 to be adjusted according to different usage environments and conditions, thereby achieving energy conservation.

[0035] It is worth noting that the moisture absorption section, dehumidification section, and cooling section of the moisture absorption wheel 110 correspond to the moisture absorption, dehumidification, and recovery states of the waterless humidifier 100. The rotation direction of the moisture absorption wheel 110 is from the moisture absorption section toward the dehumidification and cooling sections, forming a cycle of three processes: absorption, dehumidification, and cooling. In the moisture absorption state, air from the outside to the moisture absorption section passes through the moisture absorption section, where moisture is absorbed by the air. The air, free of moisture, is then discharged to the outside, thereby completing the moisture absorption process of the moisture absorption wheel 110. The moisture absorbed by the moisture absorption wheel 110 enters the dehumidification state as the moisture absorption wheel 110 rotates. In the dehumidification state, regeneration air flowing through the bypass air duct 137 or the cooling zone 113 passes through the heating device 150, where it is heated, and then flows through the dehumidification section. The moisture absorbed by the moisture absorption wheel 110 is discharged into the room through the humidification outlet 135 along with the heated regeneration air, thereby humidifying the room. The dehumidified part of the hygroscopic wheel 110 enters a cooling state as the hygroscopic wheel 110 rotates. The regenerated air flowing in from the cooling air inlet 133 will exchange heat when passing through the cooling part, thereby cooling the cooling part to restore the hygroscopic performance of the hygroscopic wheel 110 and recovering heat at the same time. However, the hygroscopic wheel 110 will also absorb moisture in the regenerated air while restoring the hygroscopic performance, thereby reducing the absolute humidity and flow rate of the regenerated air. The regenerated air flowing from the bypass air duct 137 to the heating device 150 does not need to pass through the hygroscopic wheel 110, so the humidity and flow rate of the regenerated air can be replenished.

[0036] In this embodiment, the partition structures 131 are disposed on opposite sides of the moisture absorption wheel 110. The partition structures 131 are three partition plates disposed on the housing 130. The three partition plates are disposed radially along the moisture absorption wheel 110, thereby dividing the moisture absorption wheel 110 into sector-shaped areas of different sizes corresponding to the moisture absorption zone, the moisture release zone, and the cooling zone 113.

[0037] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the waterless humidification device 100 further includes a regeneration fan 190. The regeneration fan 190 is mounted on the housing 130. The regeneration fan 190 allows the regeneration air to flow sequentially through the cooling zone 113, the heating device 150, and the desorption zone 115, and finally be discharged into the room through the humidification outlet 135. The regeneration fan 190 also allows the regeneration air to flow sequentially through the bypass air duct 137, the heating device 150, and the desorption zone 115, and then be discharged through the humidification outlet 135. The regeneration fan 190 allows the regeneration air to be simultaneously blown into the cooling zone 113 and the bypass air duct 137, resulting in a simpler and more compact structure.

[0038] In some other embodiments of the present application, the cooling zone 113 and the bypass air duct 137 may also be blown with a regeneration fan 190 respectively.

[0039] In this embodiment, the bypass duct 137 is parallel to the axis of the moisture absorption wheel 110. This arrangement allows a single regeneration fan 190 to blow air to both the cooling zone 113 and the bypass duct 137, eliminating the need for additional air blowing equipment for the bypass duct 137 and further reducing costs. Furthermore, the length of the bypass duct 137 can be shortened, and airflow loss due to bending in the bypass duct 137 can be avoided.

[0040] In some other embodiments of the present application, the bypass air duct 137 may not be parallel to the axis of the desiccant wheel 110, and the air inlet of the bypass air duct 137 can be arranged relative to the air outlet of the regeneration fan 190, so that the regeneration air flowing out of the air outlet of the regeneration fan 190 can be blown into the bypass air fan.

[0041] In this embodiment, the housing 130 encloses the outer side of the moisture absorption wheel 110, and the bypass air duct 137 is located at a position on the housing 130 corresponding to the outer periphery of the cooling zone 113. Specifically, the bypass air duct 137 is located at a position on the housing 130 corresponding to the arc length of the outer periphery of the cooling zone 113. In this embodiment, the placement of the bypass air duct 137 at the outer periphery of the housing 130 corresponding to the arc length of the fan-shaped cooling zone 113 facilitates the air blowing device to simultaneously blow regeneration air into the cooling zone 113 and the bypass air duct 137.

[0042] In this embodiment, a mounting hole 117 is provided on the moisture absorption wheel 110, and the housing 130 extends into the mounting hole 117, so that the moisture absorption wheel 110 can rotate along the housing 130. The bypass air duct 137 is provided at a position corresponding to the inner periphery of the housing 130 and the cooling zone 113. The placement of the bypass air duct 137 at the inner periphery of the housing 130 corresponding to the cooling zone 113 facilitates the regeneration fan 190 to simultaneously blow regeneration air into the cooling zone 113 and the bypass air duct 137.

[0043] In this embodiment, the cooling air inlet 133 is connected to the bypass air duct 137, and the air outlet of the regeneration blower 190 is connected to the cooling air inlet 133, so that the air flowing in through the cooling air inlet 133 can partially flow into the bypass air duct 137 and the other part into the cooling zone 113. In this embodiment, the cooling air inlet 133 is connected to the bypass air duct 137, so that the regeneration air flowing in through the cooling air inlet 133 can be supplied to the cooling zone 113 and the bypass air duct 137 at the same time, making the flow channel design simpler.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the housing 130 includes a first housing 139 and a second housing 141 that are connected to each other. The first housing 139 extends into the mounting hole 117 so that the moisture absorption wheel 110 can rotate along the first housing 139. The second housing 141 surrounds the outer side of the moisture absorption wheel 110 to isolate the moisture absorption wheel 110 from the outside. The bypass air duct 137 includes a first air duct 143 and a second air duct 145. The first air duct 143 is arranged at a position corresponding to the inner periphery of the first housing 139 and the cooling zone 113. The second air duct 145 is arranged at a position corresponding to the outer periphery of the second housing 141 and the cooling zone 113. The regenerated air flowing into the first air duct 143 and the second air duct 145 passes through the heating device 150 and the desorption zone 115 in sequence and is discharged from the humidification outlet 135. The valve body 170 includes a first valve body 171 and a second valve body 173. First valve body 171 is installed in first air duct 143 to control the opening of first air duct 143. Second valve body 173 is installed in second air duct 145 to control the opening of second air duct 145. In this embodiment, bypass air duct 137 is configured as first air duct 143 and second air duct 145, and the first air duct 143 and second air duct 145 correspond to the outer periphery and inner periphery of cooling zone 113, respectively. This allows more regenerated air to pass through bypass air duct 137 within a limited space, thereby better compensating for air volume loss. Simultaneously, a single fan can be used to blow regenerated air into first air duct 143, second air duct 145, and cooling zone 113.

[0045] In this embodiment, the first air duct 143 and the second air duct 145 are both parallel to the axis of the moisture absorption wheel 110. In other embodiments of the present application, one of the first air duct 143 and the second air duct 145 may be parallel to the axis of the moisture absorption wheel 110, or both of them may not be parallel to the axis of the moisture absorption wheel 110.

[0046] In this embodiment, the valve body 170 is movably mounted on the housing 130. The valve body 170 can move relative to the housing 130 to partially block, close, or open the bypass air passage 137. By moving the valve body 170 relative to the housing 130 to partially block, close, or open the bypass air passage 137, the opening of the bypass air passage 137 can be more conveniently controlled.

[0047] Please refer to Figure 3 and Figure 4 In this embodiment, the waterless humidification device 100 further includes an adsorption fan 210 mounted on the housing 130. The housing 130 is provided with an adsorption inlet 147 and an adsorption outlet 149. The adsorption fan 210 is in communication with the adsorption inlet 147 and allows the gas flowing into the adsorption inlet 147 to pass through the adsorption zone 111 and then out through the adsorption outlet 149. The adsorption fan 210, the adsorption inlet 147, and the adsorption outlet 149 allow air to flow into the moisture absorption zone, allowing the adsorption zone 111 to absorb more moisture.

[0048] In this embodiment, the valve body 170 includes a shielding member (not marked in the figure) and a driving member (not shown in the figure). The shielding member is movably mounted on the shell 130, and the driving member can drive the shielding member to move relative to the shell 130 to partially block, close or open the bypass air duct 137.

[0049] It is worth noting that the opening of the valve body 170 can be determined by operating conditions such as the speed of the adsorption fan 210, the adsorption air volume, the speed of the regeneration fan 190, the regeneration air volume, the heating power of the heater 150, and the speed of the moisture absorption rotor. The opening of the valve body 170 can also be determined by a combination of the adsorption inlet 147 temperature, the adsorption inlet 147 humidity, the adsorption outlet 149 temperature, the adsorption outlet 149 humidity, the cooling inlet temperature, the cooling inlet humidity, and the humidification outlet 135 temperature and humidity.

[0050] The working principles and beneficial effects of the waterless humidification device 100 and the air conditioner provided by the embodiment of the present invention include:

[0051] This embodiment provides a cooling air inlet 133 connected to the cooling zone 113. Regeneration air flowing through the cooling air inlet 133 sequentially flows through the cooling zone 113, the heating device 150, and the desorption zone 115 before being discharged through the humidification outlet 135. This reduces the temperature of the cooling zone 113, thereby restoring the moisture absorption capacity of the moisture absorption wheel 110 and recovering heat. A bypass air duct 137 is provided in the housing 130 and connects the bypass air duct 137 to the air inlet side of the heating device 150. This allows the regeneration air flowing through the bypass air duct 137 to be directly heated and dehumidified without passing through the moisture absorption wheel 110, thereby replenishing the regeneration air volume and humidity. Furthermore, a valve 170 is provided in the bypass air duct 137. This valve 170 controls the opening of the bypass air duct 137, allowing it to be adjusted according to different operating environments and conditions, thereby achieving energy savings.

[0052] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
