Generally, the air conditioning unit includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigeration cycle that performs the compression, condensation, expansion, and evaporation processes of a refrigerant is driven to cool or heat the designated space.

[0003] The aforementioned predetermined space can be proposed in various ways depending on the location where the air conditioner is used. For example, when the air conditioner is placed in a home or office, the aforementioned predetermined space may be an indoor space of a house or building.

[0004] When the air conditioner performs cooling operation, the outdoor heat exchanger equipped in the outdoor unit functions as a condenser, and the indoor heat exchanger equipped in the indoor unit functions as an evaporator. On the other hand, when the air conditioner performs heating operation, the indoor heat exchanger functions as a condenser, and the outdoor heat exchanger functions as an evaporator.

[0005] An air conditioning unit can be used as an air conditioning system for dehumidification. Generally, a dehumidifying air conditioning system can operate to reduce the absolute humidity of the air to a target level through dehumidification using a dehumidification rotor.

[0006] Meanwhile, in the case of a conventional air conditioning device, cooling lines and heating lines are provided on the surface of the dehumidification rotor to improve efficiency in the dehumidification and regeneration regions of the dehumidification rotor.

[0007] In particular, the efficiency of the dehumidification process was improved by performing a cooling process through the cooling line during the dehumidification process, and the efficiency of the regeneration process was improved by performing a heating process through the heating line during the regeneration process.

[0008] However, these conventional air conditioning systems had the problem of reduced operating efficiency because additional power was consumed by the cooling and heating wires.

[0124] When moisture is adsorbed in the dehumidification area (355) located in the first flow path (100) for a predetermined period of time, the dehumidification rotor (350) rotates, and the dehumidification area (355) is located in the second flow path (200) to form a regeneration area (356) and regeneration can be performed.

[0125] And, the regeneration area (356) located in the second Euro section (200) can be moved to the first Euro section (100) to form a dehumidification area (355) and perform dehumidification.

[0126] For example, the dehumidification rotor (350) continuously rotates, and during the rotation process, the area of ​​the dehumidification rotor (350) can repeatedly perform dehumidification and regeneration operations by switching between the dehumidification area (355) and the regeneration area (356).

[0127] Hereinafter, various embodiments of the dehumidification rotor (350) will be described with reference to the drawings.

[0128] FIG. 6 is a perspective view showing the configuration of a dehumidification rotor according to a first embodiment of the present invention, FIG. 7 is an exploded perspective view showing the configuration of a dehumidification rotor according to a first embodiment of the present invention, FIG. 8 is a drawing showing the rotation axis and surrounding configuration of a dehumidification rotor according to a first embodiment of the present invention, and FIG. 9 is a drawing showing the configuration of the spokes and heat pipes of a dehumidification rotor according to a first embodiment of the present invention.

[0129] Referring to FIGS. 6 to 9, a dehumidifying rotor (350) according to the first embodiment of the present invention may include a rim (351) forming an internal space (351a) into which a dehumidifying member is filled, and spokes (370) connected to the rim (351) and extending radially toward a hub (352).

[0130] The above rim (351) may have a cylindrical shape with both ends open. One end of the above rim (351) may form an inlet end where air is introduced, and the other end may form an outlet end where air is discharged.

[0131] The rim (351) may form a coupling hole (351b) into which the spoke (370) is coupled. The coupling hole (351b) is formed to be recessed from one end of the rim (351) toward the other end, and the spoke (370) may be fitted axially from one end of the rim (351) toward the other end.

[0132] In order to prevent the spoke (370) from coming off, the coupling hole (351b) may not be formed to the other end of the rim (351) but may be formed to a set distance from the other end.

[0133] As another example, it may be provided in the form of a groove that is recessed in the inner circumference of the rim (351) rather than the aforementioned coupling hole.

[0134] The above spoke (370) may have a thin plate shape.

[0135] The above spokes (370) may be provided in multiple numbers. The multiple spokes (370) may be connected to different points on the outer surface of the hub (352) and may extend radially to be connected to different points on the inner surface of the rim (351).

[0136] For example, the plurality of spokes (370) may include six spokes (370a to 370f). However, the number of spokes (370) may not be limited thereto.

[0137] The dehumidifying rotor (350) may include a hub (352) that provides the rotational center of the dehumidifying rotor (350). For example, the hub (352) may have a roughly cylindrical shape and may include an outer surface to which the plurality of spokes (370) are connected.

[0138] A through hole (352a) to which the spoke (370) is joined may be formed in the hub (352). The through hole (352a) may be formed as a depression on the outer surface of the hub (352) and configured to allow a heat pipe (400) to pass through.

[0139] The dehumidification rotor (350) may include a rotation shaft (353) that is rotatably supported in the housing (310). The rotation shaft (353) is provided to protrude from both ends of the hub (352) and may be rotatably coupled to the first and second supports (315a, 315b) of the housing (310).

[0140] The interior of the above rim (351) is filled with a dehumidifying member (380), and when air passes through the dehumidifying member (380), moisture can be adsorbed or desorbed due to the difference in moisture content (relative humidity) between the dehumidifying member (380) and the air.

[0141] When high-humidity air flowing into the first Euro section (100) comes into contact with a dry dehumidifying member (380), moisture in the air is adsorbed onto the dehumidifying member (380) due to the difference in relative humidity, and heat generation may occur during this process (adsorption heat generation).

[0142] Due to the above-mentioned adsorption heat generation, the temperature of the air in contact with the dehumidifying member (380) rises and the relative humidity decreases, and the difference in relative humidity between the dehumidifying member (380) and the air decreases, which may lead to a decrease in dehumidification performance.

[0143] To improve this, the air can be cooled by the heat pipe (400) described below to increase the relative humidity of the air, thereby creating an environment favorable for the dehumidifying member (380) to adsorb moisture. That is, the higher the relative humidity of the air in contact with the regenerated, dry dehumidifying member (380), the better the moisture adsorption action can be performed.

[0144] Meanwhile, when air is introduced into the second Euro section (200) and passes through the heater (220), the temperature of the air increases and the relative humidity decreases, thereby creating an environment favorable for the dehumidifying member (380) to desorb moisture. In addition, the output of the heater (220) can be reduced by providing additional heat through the provision of the heat pipe (400). That is, the drier the air contacting the highly humid dehumidifying member (380) after moisture adsorption, the better the moisture desorption action can be performed.

[0145] Below, the configuration of the heat pipe (400) and the relative arrangement structure with respect to the dehumidification rotor (350) will be explained in more detail.

[0146] The above dehumidification rotor (350) may include a heat pipe (400) in which a working fluid is enclosed and circulates while undergoing a phase change. For example, the working fluid may include ammonia, methanol, ethanol, or water.

[0147] The heat pipe (400) may be configured to have a wick through which a liquid fluid flows within a casing, and to form a vapor passage inside the wick.

[0148] The heat pipe (400) may include a first side portion forming a condensation area on one side relative to the center portion of the heat pipe (400) and a second side portion forming an evaporation area on the other side relative to the center portion.

[0149] The first side may have an area of ​​a length set at one end of the heat pipe (400), and the second side may have an area of ​​a length set at the other end of the heat pipe (400).

[0150] The working fluid vaporized in the above evaporation region can flow from the evaporation region through the central part of the heat pipe (400) to the condensation region. Then, the fluid liquefied while dissipating heat in the condensation region returns to the evaporation region by capillary force. This circulation of the working fluid can be repeated.

[0151] The heat pipe (400) may be positioned to be embedded or inserted into the plurality of spokes (370).

[0152] The above spoke (370) may include a spoke body (371) having a plate shape and forming a predetermined area, and an insertion hole (372) formed through the end of the spoke body (371) into which the heat pipe (400) is inserted.

[0153] The insertion hole (372) may be recessed from the radially outer end of the spoke body (371) and recessed radially inward toward the outer surface of the hub (352). Here, the radially outer end of the spoke body (371) can be understood as a part connected to the inner surface of the rim (351).

[0154] The heat pipe (400) can be inserted radially into the insertion hole (372).

[0155] The above insertion holes (372) are formed in multiple numbers, and the multiple insertion holes (372) can be spaced apart in the axial direction of the spoke (370).

[0156] Referring to FIG. 8, the heat pipe (400) can be extended linearly in a radial manner.

[0157] In detail, the heat pipe (400) is inserted into the insertion hole (372) of one spoke (370b), extends toward the hub (352), and can be connected to another spoke (370e) by passing through the hub (352).

[0158] At this time, the heat pipe (400) can be inserted into the insertion hole (372) of the other spoke (370e) and extended further in the radial direction. The first spoke (370b) and the other spoke (370e) can be understood as spokes facing each other with respect to the hub (352).

[0159] That is, the heat pipe (400) can be inserted into one spoke (370b) and extend inwardly radially from one point of the rim (351) to penetrate the hub (352) and inserted into another spoke (3770e) to extend to another point of the rim (351).

[0160] The portion of the heat pipe (400) inserted into the first spoke (370b) can form a first side (410) that forms an evaporation region. And, the portion of the heat pipe (400) inserted into the other spoke (370e) can form a second side (420) that forms a condensation region.

[0161] The first side (410) may form a dehumidification area of ​​the dehumidification rotor, and the second side (420) may form a regeneration area of ​​the dehumidification rotor.

[0162] The virtual extension line separating the dehumidification area and the regeneration area may be defined to pass through the space between two adjacent spokes (370). The first side (410) may be positioned on one side relative to the virtual extension line, and the second side (420) may be positioned on the other side relative to the virtual extension line.

[0163] The heat pipe (400) may include a hub connecting part (430) that extends through the hub (352) from the first side (410) and is connected to the second side (420).

[0164] In this embodiment, the plurality of spokes (370) includes six spokes, and the heat pipe (400) can be inserted into and extended between two spokes (370) facing each other. Accordingly, in this embodiment, the plurality of heat pipes (400) can be understood as constituting three sets of heat pipes (400) extending in three different directions.

[0165] The three sets of heat pipes (400) extending in three different directions can be arranged to intersect each other inside the hub (352) when passing through the hub (352).

[0166] For example, as illustrated in FIG. 8, the three sets of heat pipes (400) may include a first heat pipe (401) extending in a first direction inside the hub (352), a second heat pipe (402) extending in a second direction, and a third heat pipe (403) extending in a third direction.

[0167] Each set of heat pipes (400) may include a plurality of pipes (401a, 401b, 401c). The plurality of pipes (401a, 401b, 401c) may be spaced apart in the axial direction of the spoke (370) and inserted into the spoke (370).

[0168] In FIG. 9, only three reference numerals (401a, 401b, 401c) are used to describe multiple pipes, but as disclosed in the drawing, a larger number of heat pipes may be spaced apart in the axial direction.

[0169] In this way, a plurality of heat pipes (400) can be stably supported on the spokes (370) and inserted into the spokes (370) and arranged densely, thereby increasing the heat transfer area with the air passing through the interior of the rim (351). That is, the spokes (370) can act as heat exchange fins that increase the heat transfer area.

[0170] Since the working fluid evaporates in the first side (410), the air passing through the first side (410) is cooled, and the dehumidification performance can be improved.

[0171] Meanwhile, since condensation of the working fluid occurs in the second side (420), the air passing through the second side (420) is heated, and the regeneration performance can be improved.

[0172] FIG. 10 is a perspective view showing the configuration of a dehumidification rotor according to a second embodiment of the present invention, FIG. 11 is an exploded perspective view showing the configuration of a dehumidification rotor according to a second embodiment of the present invention, FIG. 12 is a drawing showing the rotation axis of a dehumidification rotor according to a second embodiment of the present invention, and FIG. 13 is a drawing showing the configuration of spokes and heat pipes of a dehumidification rotor according to a second embodiment of the present invention.

[0173] Referring to FIGS. 10 to 13, a dehumidifying rotor (350a) according to a second embodiment of the present invention may include a rim (351) forming an internal space (351a) in which a dehumidifying member is filled, and spokes (370) connected to the inner circumference of the rim (351) and extending radially toward a hub (352).

[0174] The overall configuration of the above rim (351), hub (352), and spoke (370) is similar to the description of the first embodiment. Therefore, regarding parts identical to the first embodiment, the description and reference numerals of the first embodiment are used, and the configuration different from the first embodiment is described with an emphasis.

[0175] The dehumidifying rotor (350) may include a hub (352) that provides the rotational center of the dehumidifying rotor (350). For example, the hub (352) may have a roughly cylindrical shape and may include an outer surface to which the plurality of spokes (370) are connected.

[0176] A groove (352b) into which at least a portion of the spoke (370) is inserted may be formed in the hub (352). The groove (352b) may be formed as a depression on the outer surface of the hub (352).

[0177] The above dehumidification rotor (350) may include a heat pipe (500) in which a working fluid is sealed and circulates while undergoing a phase change. The description regarding the internal configuration of the heat pipe (500) is based on the description regarding the heat pipe (400) described in the first embodiment.

[0178] The heat pipe (500) may be arranged to penetrate the plurality of spokes (370) in a circumferential direction. For example, the heat pipe (500) may be configured to have a circular or ring shape.

[0179] The above spoke (370) may include a spoke body (371) having a plate shape and forming a predetermined area, and a hole (373) penetrating the spoke body (371) through which the heat pipe (500) passes.

[0180] The above holes (373) are formed in multiple numbers, and the multiple holes (373) can be arranged to form multiple rows and multiple columns over the area of ​​the spoke body (371) (matrix arrangement structure).

[0181] The heat pipe (500) may have a ring shape to extend in a circumferential direction by penetrating a plurality of spokes (370). In this embodiment, six spokes (370) are provided, and the heat pipe (500) may penetrate five of the six spokes (370) and not penetrate the remaining one spoke (370f, see FIG. 11). That is, the hole (373) may not be formed in the remaining one spoke (370f).

[0182] Among the heat pipe (500) having the above ring shape, the first side (510) may form an evaporation region and the second side (520) may form a condensation region. The first side (510) may form a dehumidification region of the dehumidification rotor, and the second side (520) may form a regeneration region of the dehumidification rotor.

[0183] The virtual extension line separating the dehumidification area and the regeneration area can be defined as extending along the spoke (370). For example, based on FIG. 10, the virtual extension line can be defined as passing through the third spoke (370c) and the sixth spoke (370f). The first side (510) can be positioned on one side based on the virtual extension line, and the second side (520) can be positioned on the other side based on the virtual extension line.

[0184] The remaining spoke (370f) that the heat pipe (500) does not pass through can be understood as a partition spoke that separates the first side (510) and the second side (520).

[0185] That is, among the ring-shaped heat pipe (500), the first side (510) and the second side (520) are arranged adjacent to both sides of the spoke (370f) and may not penetrate the spoke (370f). Accordingly, the gaseous fluid evaporated from the first side (510) flows in a circumferential direction (e.g., clockwise) to reach the second side (520), and the fluid condensed from the second side (520) flows in a circumferential direction (e.g., counterclockwise) to reach the first side (510).

[0186] The heat pipe (500) comprises a plurality of heat pipes (501, 502, 503, 504), and the plurality of heat pipes may include a first heat pipe (501) forming a first diameter and a second heat pipe (502) forming a second diameter larger than the first diameter. The second heat pipe (502) may be arranged to surround the first heat pipe (501).

[0187] The above plurality of heat pipes may include a third heat pipe (503) forming a third diameter larger than the second diameter and a fourth heat pipe (504) forming a fourth diameter larger than the third diameter.

[0188] The third heat pipe (503) may be arranged to surround the second heat pipe (502), and the fourth heat pipe (504) may be arranged to surround the third heat pipe (503).

[0189] The first to fourth heat pipes (501, 502, 503, 504) may each include a plurality of pipes spaced apart in the axial direction of the spoke (370). In FIG. 10, a number is assigned to the plurality of pipes (501a, 501b, 501c) spaced apart in the axial direction of the spoke (370) with respect to the first heat pipe (501).

[0190] In FIG. 10, only three reference numerals (501a, 501b, 501c) are used to describe multiple pipes, but as disclosed in the drawing, a larger number of heat pipes may be spaced apart in the axial direction.

[0191] In this way, a plurality of heat pipes (500) can be stably supported on the spokes (370) and are arranged densely in the circumferential direction through the spokes (370), so that the heat transfer area with the air passing through the interior of the rim (351) can be increased. That is, the spokes (370) can act as heat exchange fins that increase the heat transfer area.

[0192] In this way, since the working fluid evaporates in the first side (510), the air passing through the first side (510) is cooled, and the dehumidification performance can be improved.

[0193] Meanwhile, since condensation of the working fluid occurs in the second side (520), the air passing through the second side (520) is heated, and the regeneration performance can be improved.

[0194] FIG. 14 is a perspective view showing the configuration of a dehumidification rotor according to a third embodiment of the present invention, FIG. 15 is an exploded perspective view showing the configuration of a dehumidification rotor according to a third embodiment of the present invention, and FIG. 16 is a drawing showing the configuration of spokes and heat pipes of a dehumidification rotor according to a third embodiment of the present invention.

[0195] Referring to FIGS. 14 to 16, a dehumidification rotor (350b) according to the third embodiment of the present invention may include a plurality of heat pipes (401, 402, 403) that are inserted into a spoke (370) and extend radially and linearly, and a plurality of heat pipes (501, 502, 503, 504) that penetrate the spoke (370) and extend in a circumferential direction.

[0196] That is, the heat pipe assembly of the third embodiment can be understood as a combination of the radial heat pipe (400) described in the first embodiment and the ring-shaped (circular) heat pipe (500) described in the second embodiment.

[0197] For convenience of explanation, the above heat pipes (401, 402, 403) may be named "first heat pipe set" and the above heat pipes (501, 502, 503, 504) may be named.

[0198] A plurality of heat pipes (401, 402, 403) constituting the first heat pipe set can be inserted into the insertion hole (372) of the spoke (370), extend radially, and be arranged to penetrate the hub (352).

[0199] Since the above spoke (370) includes multiple spokes (370), the heat pipe (401) inserted into two spokes (370a, 370d) facing each other can extend in a first direction inside the hub (352).

[0200] And, the heat pipe (402) inserted into the two spokes (370b, 370e) facing each other can extend in a second direction inside the hub (352).

[0201] And, the heat pipe (403) inserted into the two spokes (370c, 370f) facing each other can extend in a third direction inside the hub (352).

[0202] The first direction, the second direction, and the third direction may intersect by forming different directions.

[0203] A plurality of heat pipes (501, 502, 503, 504) constituting the second heat pipe set are supported by spokes (370) and can extend in a circumferential direction. The feature of configuring the plurality of heat pipes (501, 502, 503, 504) to have different diameters is based on the description in the second embodiment.

[0204] The spoke (370) may include a pipe support (374) that supports the plurality of heat pipes (501, 502, 503, 504). The pipe support (374) is provided at the axial end of the spoke (370) and may be configured to have the shape of a rib through which the plurality of heat pipes (501, 502, 503, 504) pass.

[0205] The above pipe support (374) may be provided to each of the remaining spokes (370), excluding one spoke (370f) among the plurality of spokes (370). As described in the second embodiment, the one spoke (370f) may be understood as a partition spoke that partitions the first side (510) and the second side (520).

[0206] The above plurality of heat pipes (501, 502, 503, 504) may include a first side (510) that forms an evaporation area of ​​a set length at one end of the heat pipe and a second side (520) that forms a condensation area of ​​a set length at the other end of the heat pipe.

[0207] A virtual extension line separating the dehumidification area and the regeneration area of ​​the dehumidification rotor can be defined as extending along the spoke (370). For example, based on FIG. 14, the virtual extension line can be defined as passing through the third spoke (370c) and the sixth spoke (370f). The first side (510) can be positioned on one side based on the virtual extension line, and the second side (520) can be positioned on the other side based on the virtual extension line.

[0208] The first side (510) of the plurality of heat pipes (501, 502, 503, 504) constituting the second heat pipe set may be disposed in an area corresponding to the first side (410) of the plurality of heat pipes (401, 402, 403) constituting the first heat pipe set.

[0209] The second side (520) of the plurality of heat pipes (501, 502, 503, 504) constituting the second heat pipe set may be disposed in an area corresponding to the second side (420) of the plurality of heat pipes (401, 402, 403) constituting the first heat pipe set.

[0210] However, the heat pipe (400) inserted into the third spoke (370c) and the sixth spoke (370f) may be located on a virtual extension line separating the dehumidification area and the regeneration area.

[0211] In this way, since a plurality of heat pipes (400, 500) are stably supported on the spokes (370) and arranged closely together, the heat transfer area with the air passing through the interior of the rim (351) can be increased.

[0212] Since the working fluid evaporates at the first side (410, 510) of the plurality of heat pipes (400, 500), the air passing through the first side (410, 510) is cooled, and the dehumidification performance can be improved.

[0213] Meanwhile, since condensation of the working fluid occurs at the second side (420, 520) of the plurality of heat pipes (400, 500), the air passing through the second side (420, 520) is heated, and the regeneration performance can be improved.

[0214] FIG. 17 is a psychrometric chart showing a comparison between the prior art and the present invention regarding changes in physical properties during the dehumidification process of the dehumidification rotor, and FIG. 18 is a psychrometric chart showing a comparison between the prior art and the present invention regarding changes in physical properties during the regeneration process of the dehumidification rotor.

[0215] First, referring to Fig. 17, the horizontal axis represents dry-bulb temperature and the vertical axis represents absolute humidity, and the solid line (ℓ) sloping upward to the right represents the saturation curve. Also, the dotted line sloping upward to the right from the lower side of the saturation curve (ℓ) represents relative humidity (ℓ), and the dotted line sloping downward to the right from the upper side of the saturation curve (ℓ) represents enthalpy (ℓ).

[0216] In the prior art, that is, in the configuration of an air conditioning device in which a heat pipe (400, 500) is not provided, when the dehumidification process is performed, the air (state Ao) introduced into the first flow path (100) passes through the dehumidification area of ​​the dehumidification rotor, and the temperature of the air rises to state A1 due to adsorption heat generation.

[0217] And, the air in state A1 can be cooled and dehumidified as it passes through the cooling coil (120) and supplied to the indoor space as state A1'. At this time, the enthalpy change (W1) of the air cooled through the cooling coil (120) becomes relatively large, so the power consumption may increase.

[0218] On the other hand, in the configuration of an air conditioning device provided with a heat pipe (400, 500) as in the present invention, when the dehumidification process is performed, the air (state Ao) introduced into the first flow path (100) passes through the dehumidification area of ​​the dehumidification rotor (350), and the temperature of the air rises relatively less to state A2 due to the cooling action of the heat pipe (400, 500).

[0219] And, the air in state A2 can be cooled and dehumidified as it passes through the cooling coil (120) and supplied to the indoor space as state A2'. At this time, the enthalpy change (W2) of the air cooled through the cooling coil (120) is relatively small, so power consumption can be reduced.

[0220] In addition, regarding the absolute humidity of the air supplied indoors, the air state (A2') of the present invention may be reduced by a set value (△) compared to the air state (A1') according to the prior art, thereby improving dehumidification performance.

[0221] Next, referring to FIG. 18, in the configuration of the conventional air conditioning device, that is, one in which a heat pipe (400, 500) is not provided, when the regeneration process is performed, the air (state A3) introduced into the second flow path (200) has its temperature raised to state A4 by the heater (220).

[0222] And, after passing through the regeneration area of ​​the dehumidification rotor in state A4, the air state changes to A5 and can be exhausted to the outside.

[0223] That is, since the enthalpy change (W1') of the air (from A3 to A4) heated through the heater (220) becomes relatively large, the power consumption may increase.

[0224] On the other hand, in the configuration of an air conditioning device provided with a heat pipe (400, 500) as in the present invention, when the regeneration process is performed, the air (state A3) introduced into the second flow path (200) is heated by the heat pipe (400, 500), so the temperature of the air can rise to A4'.

[0225] Also, since heating by the heater (220) is performed to the extent corresponding to A4' to A4, the enthalpy change (W2') is relatively small, so the power consumption can be reduced.

[0226] The present invention relates to an air conditioning device that can easily supply dehumidified air into an indoor space using a dehumidification rotor. Therefore, industrial applicability is significant.
