Some embodiments of the present disclosure provide an air conditioning apparatus 1, fig. 1 is a perspective view of an air conditioning apparatus according to some embodiments; FIG. 2 is a top view of an air conditioning apparatus with a top cover of the case removed, according to some embodiments; fig. 3 is a perspective view of an air conditioning apparatus with a top cover of a case removed according to some embodiments. As shown in fig. 1 to 3, the air conditioning apparatus 1 includes a cabinet 100 and a humidity conditioning assembly 200.

The case 100 is a substantially rectangular parallelepiped metal case, and defines a housing chamber therein. The box 100 includes a first air inlet 110, a second air inlet 120, a first air outlet 130, a second air outlet 140, and a plurality of partitions 190. The receiving chamber is partitioned by a plurality of partitions 190 into a return air duct 172 (i.e., a first duct, fig. 19 and 20) and a fresh air duct 171 (i.e., a second duct, fig. 19 and 20). The first air inlet 110, the second air inlet 120, the first air outlet 130, and the second air outlet 140 are all disposed on the side wall of the box 100.

For example, referring to fig. 1, the first air inlet 110 and the second air inlet 120 are disposed on the rear side wall of the case 100, and the first air outlet 130 and the second air outlet 140 are disposed on the right side wall and the left side wall of the case 100, respectively. Referring to fig. 1, 19 and 20, one end of the return air duct 172 is connected to the first air inlet 110, and the other end of the return air duct 172 is connected to the first air outlet 130; one end of the fresh air channel 171 is communicated with the second air inlet 120, and the other end of the fresh air channel is communicated with the second air outlet 140.

In some embodiments, as shown in fig. 3 and 4, the air conditioning apparatus 1 further includes a first fan 161 and a second fan 162. The first fan 161 is disposed in the return air duct 172 and is located near the first air outlet 130. The first fan 161 is configured to draw in indoor dirty air (i.e., return air), to make indoor return air enter the return air duct 172 through the first air inlet 110, and to be discharged outdoors through the return air duct 172 and the first air outlet 130. The second fan 162 is disposed in the fresh air duct 171 and is located near the second air outlet 140. The second fan 162 is configured to draw out outdoor fresh air, so that the outdoor fresh air enters the fresh air duct 171 through the second air inlet 120, and is sent indoors through the fresh air duct 171 and the second air outlet 140.

As shown in fig. 4 and 5, a humidity conditioning assembly 200 is disposed in the cabinet 100 and is configured to condition the humidity (e.g., dehumidify or humidify) of the air in the environment. FIG. 6 is a perspective view of a humidity conditioning assembly of an air conditioning apparatus according to some embodiments; fig. 7 is a perspective view of a humidity conditioning assembly of an air conditioning apparatus according to some embodiments from the perspective of the Q direction shown in fig. 6.

Referring to fig. 6 and 7, the humidity conditioning assembly 200 includes a wheel 210. A first portion of the wheel 210 is located in the return air duct 172 and a second portion of the wheel 210 is located in the fresh air duct 171. It should be noted that the first portion of the rotating wheel 210 and the second portion of the rotating wheel 210 may be arranged in the front-rear direction or the up-down direction.

For convenience of description, the air conditioning apparatus 1 of some embodiments of the present disclosure will be mainly described by taking an example in which a first portion of the wheel 210 is disposed above a second portion of the wheel 210.

In some embodiments, as shown in fig. 6 and 7, the wheel 210 includes a first treatment zone 212 and a second treatment zone 213. The first treatment zone 212 is one of an adsorption zone or a desorption zone, and the second treatment zone 213 is the other of the adsorption zone or the desorption zone. The fresh air duct 171 and the return air duct 172 are disposed perpendicular to the tread of the wheel 210, with at least a portion of the first treatment area 212 of the wheel 210 (i.e., the first portion of the wheel 210) being located in the return air duct 172 and at least a portion of the second treatment area 213 of the wheel 210 (i.e., the second portion of the wheel 210) being located in the fresh air duct 171.

It will be appreciated that when the fresh air and the return air flow in the corresponding air channels (the flowing directions of the fresh air and the return air are opposite), the fresh air and the return air flow through the rotating wheel 210, and the rotating wheel 210 can adsorb water vapor in the air flowing through or desorb the water vapor to humidify the air flowing through. That is, when wind (fresh air or return air) passes through the adsorption zone of the wheel 210, the wind becomes dry because the moisture carried by the wind is adsorbed by the wheel 210; in contrast, when hot air (fresh or return air is warmed by the heat exchanger before passing through the desorption zone, as will be described in more detail below) passes through the desorption zone of the rotor 210, water vapor in the desorption zone is carried away. In this manner, the wheel 210 rotates at a preset rotational speed to continuously dehumidify or humidify the air.

In some embodiments, the wheel 210 is a honeycomb structure. The wheel 210 may be made of silica gel, fiberglass, a composite of haloid salts, or molecular sieves. For example, when the wheel 210 is made of silica gel, it is possible to have a strong regeneration adsorption capacity (i.e., the capacity of the wheel 210 to adsorb water vapor again after desorbing water vapor), which is advantageous for improving the dehumidification and humidification effects of the air conditioning apparatus 1.

In some embodiments, referring to fig. 5-7, the humidity conditioning assembly 200 further includes a mounting frame 220, a first sealing portion 230, and a second sealing portion 240.

The mounting frame 220 is a rectangular parallelepiped frame structure, and the mounting frame 220 includes frame side walls 222 and defines an accommodating space therein. The frame side wall 222 is located on one side in the axial direction of the runner 210 and is disposed parallel to the end face of the runner 210. The rotating wheel 210 is disposed in the receiving space in the thickness direction of the mounting frame 220, and the wheel surface of the rotating wheel 210 is parallel to the two frame side walls 222. For example, the mounting frame 220 includes two frame side walls 222 parallel to each other, and the two frame side walls 222 are respectively located at both sides of the axial direction of the rotating wheel 210 and are respectively parallel to both side end surfaces of the rotating wheel 210.

Referring to fig. 9, the frame side wall 222 is provided with an opening 223 at a position corresponding to the end face of the wheel 210, and the aperture of the opening 223 is substantially equal to the diameter of the end face of the wheel 210. Fresh and return air flows through the wheel 210 via openings 223.

The frame side wall 222 and the end surface of the runner 210 have a first gap A1 therebetween (as shown in fig. 11A and 12A), and the first seal portion 230 is provided on the outer circumferential surface of the runner 210 in the circumferential direction of the runner 210 and abuts against the frame side wall 222 to seal the first gap A1.

In some embodiments, referring to fig. 6 and 7, the first seal 230 includes two first seal rings 235, the two first seal rings 235 extending along the circumference of the rotor 210 and being disposed at a spaced apart distance. The two first sealing rings 235 are respectively abutted with the two frame side walls 222 to seal a first gap A1 between the end surface of the rotating wheel 210 and the frame side walls 222, so that air in the return air duct 172 and the fresh air duct 171 cannot enter the accommodating space of the mounting frame 220 through the first gap A1.

In some embodiments, referring to fig. 6 and 7, the mounting frame 220 further includes a mounting beam 221, the mounting beam 221 extending along a length of the mounting frame 220 and being disposed on the frame side walls 222. The mounting beam 221 is located at the middle in the height direction of the opening 223. Wherein the number of mounting beams 221 may be one or more.

In some embodiments, referring to fig. 6 and 7, the mounting frame 220 includes two mounting beams 221, the two mounting beams 221 extending along the length of the mounting frame 220 and being disposed on the frame side walls 222, respectively.

FIG. 11A is a cross-sectional view taken along line A-A of FIG. 10; fig. 11B is a partial enlarged view of the circle E1 in fig. 11A.

In some embodiments, referring to fig. 7, 11A and 11B, the wheel 210 further includes a shaft 211. The rotating shaft 211 penetrates through the rotating wheel 210, and two ends of the rotating shaft 211 are respectively arranged on the two mounting beams 221. The second sealing portion 240 includes a sealing strip 245. The sealing strip 245 is provided on the mounting beam 221 along the length direction of the mounting beam 221 and abuts against the end face of the wheel 210 to seal the gap between the mounting beam 221 and the end face of the wheel 210. In this way, the two air flows from the return air duct 172 and the fresh air duct 171 flowing through the rotating wheel 210 can be separated, so that the dehumidified dry air flow and the dehumidified wet air flow can be separated, which is beneficial to improving the dehumidifying effect and the humidifying effect of the air conditioning apparatus 1 on air.

It will be appreciated that the arrangement of the mounting frame 220 provides mounting carriers and accommodation spaces for the wheel 210 and its driving structure, facilitates the production and assembly of the air conditioning apparatus 1, and is beneficial to improving production efficiency.

Fig. 10 is a top view of a humidity conditioning assembly of an air conditioning apparatus according to some embodiments.

In some embodiments, referring to fig. 3 and 10, the plurality of baffles 190 includes a first baffle 191. The first spacer 191 is fixedly coupled to a side of one mounting beam 221 of the two mounting beams 221, which is away from the end surface of the rotor 210. The first partition 191 is configured to separate the fresh air duct 171 and the return air duct 172. It will be appreciated that fig. 3 only shows a first spacer 191 located on one side of the humidity conditioning assembly 200, and a second spacer is also provided on the other side of the humidity conditioning assembly 200, which is fixedly connected to the side of the other mounting beam 221 of the two mounting beams 221 remote from the rotor 210. The second partition is configured to separate the fresh air duct 171 and the return air duct 172.

In some embodiments, first seal 235 and seal 245 are both silicone coated with teflon coating on their surfaces, thereby providing high temperature, abrasion and surface smoothness.

FIG. 12A is a cross-sectional view taken along line B-B in FIG. 10; fig. 12B is a partial enlarged view at a circle E2 in fig. 12A.

In some embodiments, referring to fig. 6, 10 and 12B, the first seal ring 235 is a unitary structure and includes a first fixing portion 231 and a first burring portion 232. The first fixing portion 231 is provided at one end of the outer circumferential surface of the rotating wheel 210 in the axial direction. The first flange portion 232 is disposed at a free end of the first fixing portion 231 and abuts against the corresponding mounting side wall 222, so that the return air duct 172 and the fresh air duct 171 can be sealed by the first sealing ring 235, and air flows in the return air duct 172 and the fresh air duct 171 are prevented from entering the mounting frame 220 through a first gap A1 between the rotating wheel 210 and the frame side wall 222.

FIG. 13 is a cross-sectional view of a humidity conditioning assembly of an air conditioning apparatus according to some embodiments; fig. 14 is a partial enlarged view of the circle C1 in fig. 13.

For example, referring to fig. 13 and 14, the humidity conditioning assembly 200 further includes a clamp 290. The first fixing portion 231 is fixed to the outer circumferential surface of the wheel 210 by the yoke 290. It will be appreciated that when the rotating wheel 210 rotates, the first sealing portion 230 rotates synchronously with the rotating wheel 210, and the first flange portion 232 and the mounting sidewall 222 rub against each other to seal the return air duct 172 from the fresh air duct 171.

In some embodiments, the portion of the frame sidewall 222 in contact with the first flange portion 232 is made of stainless steel, so that a friction coefficient between the frame sidewall 222 and the first flange portion 232 may be reduced, and thus, power of a driving motor driving the rotation wheel 210 may be reduced, and energy may be saved.

Fig. 12C is a partial enlarged view at a circle E3 in fig. 12A.

In some embodiments, referring to fig. 10, 12A and 12C, the sealing strip 245 is of unitary construction and includes a second securing portion 241 and a second flange portion 242. The second fixing portion 241 is fixedly connected to the mounting beam 221 along the mounting beam 221, and the second flange portion 242 is disposed at a free end of the second fixing portion 241, and extends toward the wheel 210 along an end of the second fixing portion 241 near the wheel 210 and in a direction away from the axis of the wheel to abut against an end surface of the wheel 210, so that a second gap A2 (see fig. 12C) between the end surface of the wheel 210 and the mounting beam 221 (or the partition) can be sealed by the sealing strip 245. It will be appreciated that when the rotor 210 rotates, the second seal portion 240 is stationary, and the second flange portion 242 rubs against the end surface of the rotor 210 to seal the second gap A2.

In some embodiments, referring to fig. 12C, the mounting frame 220 further includes a securing plate 224. The fixing plate 224 extends along the length direction of the mounting beam 221 and is fixedly connected with the mounting beam 221 by a screw. A third gap A3 is reserved between the mounting beam 221 and the fixing plate 224, and the second fixing portion 241 is interference-fitted in the third gap A3. For example, the mounting beam 221 and the fixing plate 224 are both metal members, so that the reliability of interference mounting of the second fixing portion 241 is advantageously improved.

In some embodiments, referring to fig. 6 and 7, the second sealing portion 240 includes four sealing strips 245, each two sealing strips 245 are disposed on one mounting beam 221 of the two mounting beams 221 and symmetrically disposed about the rotation axis 211, and bending directions of the second flange portions 242 of the two sealing strips 245 are opposite. That is, the second burring parts 242 of the two weather strips 245 provided on the same mounting beam 221 are bent in opposite directions when they are abutted against the wheel 210, and the side of each second burring part 242 close to the wheel 210 extends toward the rotation direction of the wheel 210.

In some embodiments, referring to fig. 9, the inner diameter of the opening 223 at a position close to the mounting beam 221 is increased (as indicated by a P region in the drawing), so that the sealing reliability at the end point of the second sealing part 240 can be improved, and thus leakage of return air and fresh air from the second gap A2 or the third gap A3 can be prevented.

FIG. 15 is a cross-sectional view of another humidity conditioning assembly of an air conditioning apparatus according to some embodiments; fig. 16 is a partial enlarged view of the circle C2 in fig. 15.

In some embodiments, referring to fig. 15 and 16, the humidity conditioning assembly 200 further includes a support 270. The support 270 extends in the circumferential direction of the wheel 210. In this case, two first sealing rings 235 are disposed at a distance from each other radially outside the support 270, and effective support of the first sealing rings 235 can be achieved by the support 270.

For example, the humidity conditioning assembly 200 includes two supports 270. Two support members 270 extend in the circumferential direction of the rotor 210 and are disposed at a distance from each other. In this case, two first seal rings 235 are provided radially outward of the two supports 270, respectively. The structures of the first seal ring 235 and the support member 270 at both ends of the rotating wheel 210 in the axial direction are the same, and the structures of the first seal ring 235 and the support member 270 at one end of the rotating wheel 210 will be described in detail below.

Referring to fig. 16, the support 270 includes a fixing ring 271 and a support 272. The fixing ring 271 is fitted around the outer circumference of the rotor 210. The support 272 is a hollow truncated cone. One axial end of the support portion 272 is connected to one side of the fixing ring 271, which is close to the frame side wall 222, and the other axial end of the support portion 272 extends in a direction close to the frame side wall 222 and away from the axis of the rotor 210. The diameter of the one end of the support portion 272 in the axial direction is smaller than the diameter of the other end of the support portion 272 in the axial direction.

The clamp 290 fastens an end of the first seal ring 235 remote from the corresponding frame side wall 222 to the outer circumferential side of the wheel 210. The other end of the first sealing ring 235 is abutted against the supporting portion 272, and the first sealing ring 235 is elastically deformed under the supporting action of the supporting portion 272, so that the other end of the first fixing portion 231 extends towards the direction close to the corresponding frame side wall 222 and away from the rotating shaft 211, and is abutted against the frame side wall 222. It will be appreciated that the support 270 and the first sealing ring 235 may be secured to the outer circumferential surface of the rotor 210 by the clip 290, which is advantageous for simplifying the installation structure of the humidity conditioning assembly 200, reducing the number of parts, and reducing the cost.

In some embodiments, as shown in fig. 16, the supporting portion 272 and the fixing ring 271 have an included angle α, and the included angle α is an obtuse angle. The included angle α may increase or decrease depending on the distance between the wheel 210 and the frame sidewall 222 and the size of the first seal 235.

Based on the above, one axial end of the first seal ring 235 is in sealing engagement with the rotor 210, and the other axial end thereof is in sealing engagement with the frame side wall 22, thereby sealing the first gap A1. In addition, by abutting the first seal ring 235 against the support portion 272 of the support 270, the first seal ring 235 is elastically deformed radially outward thereof by the supporting force of the support portion 272. Thus, when the first sealing ring 235 is mounted to the rotating wheel 210, there is a certain pre-deformation, so that the first sealing ring 235 and the rotating wheel 210 are conveniently mounted to the mounting frame 220, the mounting efficiency is improved, and the sealing effect of the first sealing ring 235 is improved.

In some embodiments, the support 270 has a certain rigidity so that the first sealing ring 235 may be stably and reliably supported. For example, the support 270 is a metal member, or a plastic member such as polyphenylene sulfide (PPS), or the like. The support 270 is an integral piece, facilitating the installation of the support 270.

In some embodiments, the support 270 includes a plurality of arcuate sheet-like sub-supports (e.g., two to six) that are spaced apart along the circumference of the wheel 210. Each sub-support includes a fixing piece fixedly connected with the outer circumferential surface of the wheel 210 and a support piece connected with the fixing piece and extending toward a direction close to the frame sidewall 222 and away from the rotation shaft 211. In this case, the first sealing ring 235 is sleeved on one side of the plurality of sub-supports far from the rotating shaft 211, and is elastically deformed under the supporting action of the plurality of supporting pieces of the plurality of sub-supports. In some embodiments, wheel 210 includes a wheel body and a rim coupled to the wheel body. The rim and the wheel body are coaxially arranged and positioned on the circumferential outer side of the wheel body. The rim is a metal member, and the first seal ring 235 and the fixing ring 271 are crimped to the outer peripheral side of the rim by the clip 290. In some embodiments, the support 270 is of unitary construction with the rim, i.e., the rim is integrally formed with the support 270.

FIG. 17 is a cross-sectional view of yet another humidity conditioning assembly of an air conditioning apparatus according to some embodiments; fig. 18 is a partial enlarged view of a circle C3 in fig. 17.

In some embodiments, referring to fig. 17 and 18, the first seal 230 further includes a second seal ring 234. The second seal 234 is located axially to one side of the rotor 210 and is located between the frame side wall 222 and the support 270.

In some embodiments, referring to fig. 17 and 18, the first seal 230 includes two second seal rings 234. Two second sealing rings 234 are respectively located at two axial sides of the rotating wheel 210 and between the corresponding frame side wall 222 and the supporting member 270. It should be understood that the first sealing ring 235 and the second sealing ring 234 on both sides of the rotating wheel 210 in the axial direction are the same as the supporting member 270, and the structure of the first sealing ring 235, the second sealing ring 234 and the supporting member 270 on one side of the rotating wheel 210 will be mainly described below as an example.

Referring to fig. 18, a second seal 234 is fixedly disposed on a side of the frame sidewall 222 adjacent the wheel 210. The second seal 234 extends in a direction around the central axis of the wheel 210. The second seal 234 abuts the corresponding frame side wall 222 and support 270, respectively. In this way, the second seal 234 can further seal the first gap A1 on the basis of the first seal 235 sealing the first gap A1, so that the reliability of the seal between the rotating wheel 210 and the frame sidewall 222 can be improved. In addition, by abutting the second seal ring 234 against the radially inner side of the support portion 272, the second seal ring 234 can also provide a certain supporting action to the support portion 272, so that the supporting action of the support portion 272 to the first seal ring 235 is more reliable.

In some embodiments, as shown in fig. 18, the second seal 234 is a unitary structure and includes a protrusion 2341 and a planar portion 2342. The protruding portion 2341 protrudes toward the wheel 210 and has an opening 2343 toward the frame side wall 222, and the flat portion 2342 is connected to the protruding portion 2341 and closes the opening 2343. The second seal ring 234 is abutted against the radially inner side of the support portion 272 by the protruding portion 2341, and the second seal ring 234 is abutted against the frame side wall 222 by the flat portion 2342. The planar portion 2342 is attached to the frame side wall 222 and fixedly connected to the frame side wall 222.

In some embodiments, referring to fig. 18, the humidity conditioning assembly 200 includes a securing tab 280 (e.g., a metal ring tab, etc.). The fixing piece 280 may be fixedly coupled to the frame sidewall 222 by a rivet or a screw, so that the flat portion 2342 may be fixedly coupled to the frame sidewall 222.

During operation of the air conditioning apparatus 1, the mounting frame 220 is stationary, the rotating wheel 210 rotates in the mounting frame 220, friction is generated between the first sealing ring 235 and the frame side wall 222, friction is generated between the second sealing ring 234 and the supporting portion 272, and therefore, the first sealing ring 235 or the second sealing ring 234 may be made of a wear-resistant material, such as a wear-resistant felt, which is beneficial to prolonging the service lives of the first sealing ring 235 and the second sealing ring 234.

Fig. 8 is a perspective view of a wheel and drive mechanism of an air conditioning device according to some embodiments.

In some embodiments, referring to fig. 8, the humidity conditioning assembly 200 further includes a drive mechanism 250. The driving mechanism 250 includes a driving motor 251, a driving pulley 252, and a transmission belt 253. The drive motor 251 is fixedly coupled to the mounting frame 220 and includes a power output 2511. The driving wheel 252 is connected to a power output end 2511 of the driving motor 251. The driving belt 253 is sleeved on the outer circumferential surfaces of the driving wheel 252 and the rotating wheel 210 (i.e. the driven wheel) so as to make the driving wheel 252 and the rotating wheel 210 in driving connection. Both the driving wheel 252 and the driving belt 253 are located in the accommodation space. It will be appreciated that some embodiments of the present disclosure employ a belt drive to rotate the wheel 210, thereby facilitating improved smoothness of operation of the wheel 210 and reduced noise and vibration during rotation of the wheel 210. In some embodiments, the drive motor 251 is a gear motor.

It should be noted that the rotation speed of the rotating wheel 210 affects the efficiency of the air conditioning apparatus 1 in conditioning the air humidity. For example, the rotation speed of the rotation wheel 210 is between 6r/h and 36r/h, and when the difference between the indoor humidity and the outdoor humidity is small, the rotation speed of the rotation wheel 210 may be set to be low (e.g., 6r/h, 9r/h, or 12 r/h) so that the rotation wheel 210 sufficiently adsorbs and desorbs the moisture. When the difference between the indoor humidity and the outdoor humidity is large, the rotation speed of the wheel 210 may be set to be high (e.g., 25r/h, 30r/h, 33r/h, or 36 r/h) to improve the efficiency of the air conditioning apparatus 1 for conditioning the air humidity.

Fig. 9 is a perspective view of a mounting frame of an air conditioning apparatus according to some embodiments.

In some embodiments, as shown in fig. 8 and 9, the mounting frame 220 further includes a frame top wall 226. The frame top wall 226 is located on top of the two frame side walls 222 and is connected to the two frame side walls 222.

In some embodiments, as shown in fig. 8, the humidity conditioning assembly 200 further includes a tensioning mechanism 260. Tensioning mechanism 260 includes a tensioning wheel 261, a tensioning arm 262, and a tensioning spring 263. One end of the tensioning arm 262 is hinged to the mounting frame 220, and the other end extends below the belt 253 and is hinged to the tensioning wheel 261. For example, the one end of the tensioning arm 262 is hinged to the frame top wall 226, or the mounting frame 220 further includes a connecting plate 225 extending vertically downward along the frame top wall 226, the one end of the tensioning arm 262 being hinged to the connecting plate 225. One end of the tension spring 263 is fixedly connected to the frame top wall 226, and the other end of the tension spring 263 is fixedly connected to the other end of the tension arm 262. The tension spring 263 applies elastic force to the belt 253 through the tension pulley 261 to put the belt 253 in tension, thereby contributing to an improvement in reliability of the driving mechanism 250.

In some embodiments, as shown in fig. 3-5, the air conditioning apparatus 1 further includes a total heat exchanger core 500. The total heat exchanger core 500 is disposed in the case 100 at a position near the first air intake 110 and the second air intake 120. A first portion of the total heat exchanger core 500 is located in the return air duct 172 and a second portion of the total heat exchanger core 500 is located in the fresh air duct 171. The total heat exchanger core 500 is configured to: when the air conditioning equipment 1 performs refrigeration dehumidification, the fresh air is cooled and dehumidified, and when the air conditioning equipment 1 heats and humidifies, the fresh air is heated and humidified.

In some embodiments, the total heat exchanger core 500 is Polypropylene (PP) and includes a plurality of layers of heat exchange membranes arranged in a spaced apart relationship, wherein the distance between each two adjacent layers of the heat exchange membranes is between 1.5mm and 2.5mm (e.g., 1.5mm, 2mm, 2.5mm, etc.). In some embodiments, the first portion and the second portion of the total heat exchanger core 500 are both positioned in the middle of the total heat exchanger core 500, thereby facilitating improved uniformity of wind speed distribution across the surface of the total heat exchanger core 500 and reduced windage.

In some embodiments, a filter screen is disposed between the first air inlet 110 and the total heat exchanger core 500, and between the second air inlet 120 and the total heat exchanger core 500, respectively. For example, the filter screen is a primary filter screen using a non-woven filter core, which can filter large particle dust and insects in the air, thereby being beneficial to improving the working stability of the total heat exchanger core 500.

In some embodiments, as shown in fig. 3-5, the air conditioning apparatus 1 further comprises a heat exchanger assembly 300. The heat exchanger assembly 300 includes a first heat exchanger 310, a second heat exchanger 320, and a third heat exchanger 330. The first heat exchanger 310 and the second heat exchanger 320 are both disposed in the return air duct 172, the third heat exchanger 330 is disposed in the fresh air duct 171, and the first heat exchanger 310 is disposed on one side (e.g., left side) of the humidity control assembly 200, and the second heat exchanger 320 and the third heat exchanger 330 are disposed on the other side (e.g., right side) of the humidity control assembly 200.

The working principle of the air conditioning apparatus 1 will be described in detail below with reference to the accompanying drawings.

FIG. 19 is a schematic diagram of an air conditioning apparatus operating in a cooling dehumidification mode in accordance with some embodiments; fig. 20 is a schematic diagram of an air conditioning apparatus operating in a heating and humidification mode according to some embodiments; FIG. 21 is a schematic illustration of an air conditioning apparatus operating in a bypass mode of outside air according to some embodiments; fig. 22 is a schematic diagram of an air conditioning apparatus according to some embodiments when operating in an internal circulation mode. In some embodiments, as shown in fig. 19 to 22, the air conditioning apparatus 1 further includes a compressor 101 and an electronic expansion valve 102. Both the compressor 101 and the electronic expansion valve 102 are connected to a heat exchanger assembly 300. The compressor 101 is configured to compress refrigerant such that low-pressure refrigerant is compressed to form high-pressure refrigerant. The electronic expansion valve 102 is configured to regulate the pressure of the refrigerant such that the high-pressure refrigerant is regulated to a low-pressure refrigerant.

When the air conditioning apparatus 1 operates in the cooling and dehumidifying mode (i.e., the first mode), referring to fig. 19, the first heat exchanger 310 and the second heat exchanger 320 function as condensers, and the third heat exchanger 330 functions as an evaporator.

It is understood that the third heat exchanger 330 may absorb heat of the fresh air flowing through the third heat exchanger 330 when it is used as an evaporator, thereby reducing the temperature of the fresh air. When the temperature of the fresh air drops to the condensation temperature of the moisture carried by the fresh air, the moisture is condensed on the outer wall of the third heat exchanger 330 and is affected by gravity, and flows downwards into the water receiving tray. In this way, the fresh air can be cooled and dehumidified by the third heat exchanger 330.

The fresh air treatment process comprises the following steps: the second fan 162 is activated and draws fresh air from the outside. Fresh air enters the fresh air duct 171 from the second air inlet 120, enters the total heat exchanger core 500 along the fresh air duct 171, and is subjected to downstream heat and mass exchange by the total heat exchanger core 500 with indoor return air (i.e., the fresh air recovers cold energy carried by indoor return air through the total heat exchanger core 500) to primarily cool and dehumidify the fresh air. Then, the fresh air exchanges heat through the third heat exchanger 330, and the temperature and humidity are further reduced. Finally, the fresh air enters the rotating wheel 210, is deeply dehumidified by the adsorption area of the rotating wheel 210, and enters the room through the second exhaust outlet 140.

The treatment process of the return air comprises the following steps: the first fan 161 is activated and draws return air from the room. The return air enters the return air duct 172 from the first air inlet 110, enters the total heat exchanger core 500 along the return air duct 172, and the total heat exchanger core 500 performs forward flow heat and mass exchange on the return air and outdoor fresh air to recover the cold carried by the return air and heat the return air. Then, the return air exchanges heat through the first heat exchanger 310, enters the desorption region of the runner 210 at a lower humidity, and desorbs and takes away the moisture stored in the runner 210. Finally, the return air carrying the moisture is discharged outdoors through the first air outlet 130 after the energy cooling capacity is recovered through the second heat exchanger 320.

When the air conditioning apparatus 1 is operated in the heating and humidifying mode (i.e., the second mode), referring to fig. 20, the first heat exchanger 310 and the second heat exchanger 320 function as evaporators, and the third heat exchanger 330 functions as a condenser.

The treatment process of the return air comprises the following steps: the first fan 161 is activated and draws relatively hot and humid return air from the room. Return air enters the return air duct 172 from the first air inlet 110, enters the total heat exchanger core 500 along the return air duct 172, and is subjected to downstream heat and mass exchange (i.e. the fresh air recovers heat carried by indoor return air through the total heat exchanger core 500) by the total heat exchanger core 500 to reduce the temperature and humidity of the return air.

In this case, in order to prevent the first heat exchanger 310 from absorbing heat, the return air temperature is lowered to precipitate moisture, and the humidification effect is lowered, the first heat exchanger 310 does not perform heat exchange work, but serves as a part of the return air duct 172. The return air enters the adsorption area of the rotating wheel 210 after passing through the first heat exchanger 310, is deeply dehumidified by the adsorption area, enters the second heat exchanger 320 for heat exchange, and is discharged outdoors through the second air outlet 140 after heat is recovered by the second heat exchanger 320. In some embodiments, the air conditioning apparatus 1 further includes a solenoid valve coupled to the first heat exchanger 310 and configured to cause the first heat exchanger 310 not to perform a heat exchange operation, but rather to be part of the return air duct 172.

The fresh air treatment process comprises the following steps: the second fan 162 is activated and draws fresh air from the outside. Fresh air enters the fresh air duct 171 from the second air inlet 120, enters the total heat exchanger core 500 along the fresh air duct 171, and is subjected to downstream heat and mass exchange by the total heat exchanger core 500 with indoor return air (i.e., the fresh air recovers heat carried by indoor return air through the total heat exchanger core 500) to heat and humidify the fresh air. Then, after the fresh air exchanges heat through the third heat exchanger 330, the temperature rises and the humidity drops, and the fresh air enters the desorption region of the rotating wheel 210 at a lower relative humidity (for example, the relative humidity is lower than 20%), and after the moisture stored in the desorption region is absorbed, the hot and humid fresh air enters the room through the second air outlet 140.

The air conditioning apparatus 1 of some embodiments of the present disclosure has two functions of cooling, dehumidifying and heating, and humidifying, and can synchronously raise or lower the temperature and humidity of indoor air, so that the comfort level of a user can be improved, and in addition, the layout of the components of the air conditioning apparatus 1 is compact, which is beneficial to realizing a miniaturized design.

In some embodiments, as shown in fig. 21, the air conditioning apparatus 1 also has an outside air bypass mode (i.e., a third mode). In this mode, the air conditioning apparatus 1 does not perform heat exchange and humidity conditioning, i.e., the wheel 210, the first fan 161, the heat exchanger assembly 300, and the compressor 101 do not operate, so that fresh air can directly enter the room, thereby contributing to energy saving and consumption reduction.

In some embodiments, referring to fig. 5 and 21, the accommodating cavity of the case 100 is partitioned by a plurality of partitions 190 into a bypass duct 173, and one end of the bypass duct 173 is connected to the fresh air duct 171 and the other end is connected to the second exhaust outlet 140. In this case, the air conditioning apparatus 1 further includes a damper assembly 400, the damper assembly 400 including a first damper 410, the first damper 410 being disposed at a position where the bypass air duct 173 communicates with the fresh air duct 171.

Referring to fig. 19 and 20, the air conditioning apparatus 1 is configured such that the first damper 410 is closed when performing cooling, dehumidifying, heating and humidifying, and fresh air and return air directly enter the total heat exchanger core 500 after entering the corresponding air duct. Referring to fig. 21, when the air conditioning apparatus 1 is operated in the outside air bypass mode, the first air valve 410 and the second air blower 162 are opened, fresh air enters the fresh air duct 171 from the first air intake 110, then enters the bypass duct 173 through the first air valve 410, and then enters the room from the second air exhaust 140.

In some embodiments, as shown in fig. 22, the air-conditioning apparatus 1 further has an internal circulation mode (i.e., a fourth mode), and when the indoor air humidity is high, the air-conditioning apparatus 1 may operate in an internal circulation mode in which the indoor return air enters the air-conditioning apparatus 1 from the first air inlet 110 to dehumidify and then returns to the indoor from the second air outlet 140 to form an internal circulation.

In some embodiments, as shown in fig. 5 and 22, the damper assembly 400 further includes a second damper 420 and a third damper 430. The second air valve 420 is disposed in the return air duct 172 and adjacent to the first air inlet 110, and the third air valve 430 is disposed in the fresh air duct 171 and adjacent to the second air inlet 120.

When the air conditioning apparatus 1 is operated in the cooling and dehumidifying mode or the heating and humidifying mode, the first air valve 410, the second air valve 420 and the third air valve 430 are all closed, and return air can enter the return air duct 172 from the first air inlet 110 and be discharged outdoors from the first air outlet 130; fresh air can enter the fresh air duct 171 from the second air inlet 120 and enter the room from the second air outlet 140.

When the air conditioning apparatus 1 is operated in the outside air bypass mode, the first air valve 410 is opened, and the second air valve 420 and the third air valve 430 are closed.

When the air conditioning device 1 operates in the internal circulation mode, referring to fig. 22, the first damper 410 is in a closed state, and the second damper 420 and the third damper 430 are opened. The first heat exchanger 310 and the second heat exchanger 320 function as condensers, and the third heat exchanger 330 functions as an evaporator. In this case, the return air may enter the return air duct 172 from the first air inlet 110 and enter the fresh air duct 171 through the second air valve 420. In the fresh air duct 171, the return air is cooled and dehumidified by the third heat exchanger 330, then deeply dehumidified by the adsorption zone of the rotating wheel 210, and finally returned to the room through the second air outlet 140. Fresh air enters the fresh air duct 171 from the second air inlet 120 and returns to the air duct 172 through the third air valve 430. In the return air duct 172, the fresh air exchanges heat through the first heat exchanger 310, the temperature rises, the humidity drops, and then enters the desorption area of the rotating wheel 210 to take away the moisture in the desorption area. Then, the high-temperature and high-humidity fresh air passes through the second heat exchanger 320, and the heat of the fresh air is recovered by the second heat exchanger 320. Finally, the fresh air carrying the moisture is discharged outdoors through the first air outlet 130.

In some embodiments, the three dampers (i.e., the first damper 410, the second damper 420, and the third damper 430) are all acrylonitrile butadiene styrene (Acrylonitrile Butadiene Styrene plastic, ABS) plastic. In some embodiments, ethylene propylene diene monomer (Ethylene Propylene Diene Monomer, EPDM) is further adhered to the surfaces of the three dampers to improve the sealing performance of the dampers when closed.

In some embodiments, the damper includes a damper shaft and a damper wall. One end of the air valve wall is connected with the air valve rotating shaft, and the air valve wall rotates around the air valve rotating shaft. The damper shaft is perpendicular to the bottom wall of the case 100, so that the damper wall does not need to work against its own weight when rotated. In some embodiments, the damper includes a stiffener disposed on the damper wall to increase the strength of the damper wall.

In some embodiments, the opening directions of the three air valves are opposite to the flowing direction of the air, so that after the first fan 161 and the second fan 162 are opened, the three air valves are locked under the action of the air pressure.

In addition, when the air conditioning apparatus is switched from the cooling and dehumidifying mode or the heating and humidifying mode to the outside air bypass mode or the inside circulation mode, the first fan 161 and the second fan 162 are turned off for a preset time and then turned on, so that the first air valve 410, the second air valve 420 or the third air valve 430 can be opened for the preset time, thereby avoiding any air valve from bearing excessive negative pressure when being opened, and being beneficial to prolonging the service lives of the three air valves.

In some embodiments, as shown in fig. 4 and 5, the air conditioning apparatus 1 further includes a drain assembly 600. The drain assembly 600 includes a drip tray 601, a water pump 610, and a drain pipe 620. The water pan 601 is disposed between the third heat exchanger 330 and the bottom wall of the box 100, and is fixedly connected with the bottom wall of the box 100. The water pan 601 is configured to collect condensed water. The water pump 610 is disposed in the water pan 601, and one end of the drain pipe 620 is connected to the water pump 610, and the other end extends to the outside. The water pump 610 may draw out condensed water accumulated in the water pan 601 and drain the condensed water by the drain pipe 620.

In some embodiments, after the air-conditioning apparatus 1 is installed, the end of the air-conditioning apparatus 1 provided with the drain pipe 620 is lower than the opposite end by 0mm to 5mm, so that condensed water accumulated in the water pan 601 can be collected on the side of the water pan 601 near the water pump 610, thereby facilitating the improvement of the drainage efficiency.

In some embodiments, the drain assembly 600 further includes a support bracket. The support frame is fixedly arranged on the water pan 601 and supported at the bottom of the third heat exchanger 330, so that the third heat exchanger 330 is spaced from the water pan 601, and the third heat exchanger 330 is prevented from being soaked by condensed water accumulated in the water pan 601.

In some embodiments, as shown in fig. 1 to 3, the air conditioning apparatus 1 further includes an electrical box 180. The electrical box 180 is fixedly provided at the front side of the case 100. A plurality of components are provided in the electrical box 180. The electrical box 180 is provided with a vent hole, and a through hole is also formed in a position of the box body 100 corresponding to the vent hole, so that negative pressure in the box body 100 can drive air in the electrical box 180 to flow so as to radiate heat of the components in the electrical box 180.

The air conditioning apparatus 1 of some embodiments of the present disclosure includes various modularized functional components, such as the humidity conditioning assembly 200, the heat exchanger assembly 300, the air valve assembly 400, the drain assembly 600, and the like, so that the air conditioning apparatus 1 can be produced in a modularized assembly manner, i.e., different modules are assembled in advance and then a plurality of modules are installed on a production line, thereby improving production efficiency.

In some embodiments, as shown in fig. 23 and 24, the air conditioning apparatus 1 further includes a plurality of suspension assemblies 150. A plurality of suspension assemblies 150 are fixedly coupled to the case 100. The air conditioning apparatus 1 is fixedly mounted on the top of a building by a plurality of suspension assemblies 150. For example, the air conditioning apparatus 1 includes four suspension assemblies 150, and one ends (e.g., lower ends) of the four suspension assemblies 150 are fixedly provided at both ends of the front side wall and both ends of the rear side wall of the cabinet 100, respectively, so that the firmness of suspension of the air conditioning apparatus 1, as well as the smoothness of operation, can be improved. In some embodiments, the upper ends of the plurality of suspension assemblies 150 are secured to the roof of the building by anchors.

Fig. 25 is a perspective view of a suspension assembly of an air conditioning apparatus according to some embodiments.

In some embodiments, as shown in fig. 24 and 25, suspension assembly 150 includes a securing member 151, a connecting member 152, two fastening nuts 153, and a plurality (e.g., two) shock absorbing members 154. The shock absorbing member 154 is a rubber ring.

Fig. 26 is a perspective view of a mount of an air conditioning device according to some embodiments.

Referring to fig. 26, the fixing member 151 includes a third fixing portion 1511 and a fourth fixing portion 1512. The third fixing portion 1511 is fixedly connected to a sidewall of the case 100, and the fourth fixing portion 1512 is connected to the third fixing portion 1511 and extends in a direction away from the case 100. The fourth fixing portion 1512 may be disposed at an upper end of the third fixing portion 1511, the fourth fixing portion 1512 including a connection groove 1513.

Referring to fig. 25 and 26, the connection member 152 is a threaded rod that is inserted in the connection groove 1513. The two shock absorbing members 154 are sleeved on the connecting member 152, and are respectively located at two sides (upper and lower sides) of the fourth fixing portion 1512. Two fastening nuts 153 can be in threaded connection with the connecting piece 152, one fastening nut 153 locks one damping piece 154 from bottom to top, and the other fastening nut 153 locks the other damping piece 154 from top to bottom, so that the fixed connection between the connecting piece 152 and the fixing piece 151 is realized. In some embodiments, the connection 152 is a suspension bolt.

It will be appreciated that the rotating components of the compressor 101, the rotor 210, the first fan 161, the second fan 162, etc. rotate at a rotational speed when in operation, and that the suspension assembly 150 resonates when the rotational speed approaches or reaches the natural frequency of the suspension assembly 150, which can cause the air conditioning apparatus 1 to vibrate severely. Therefore, the vibration absorbing member 154 for absorbing vibration is added between the fixing member 151 and the fastening nut 153, so that the vibration transmitted from the fixing member 151 to the connecting member 152 can be reduced, and the operation stability of the air conditioning apparatus 1 can be improved.

The upper end of the connector 152 is fixedly connected to the top of the building. In some embodiments, the roof of the building is a concrete structure and the connector 152 is fixedly attached to the ceiling or wall by an anchor.

For example, the third fixing portion 1511 has three fixing holes 1514, and the three fixing holes 1514 are arranged in a triangle. Three through holes are provided on the side wall of the case 100 at positions corresponding to the three fixing holes 1514. It will be appreciated that the triangular shape, with at least three fixation holes 1514 arranged in a triangle, facilitates improved stability of the connection between the third fixation portion 1511 and the case 100.

Fig. 27 is a perspective view of a reinforcing plate of an air conditioning apparatus according to some embodiments.

In some embodiments, as shown in fig. 27, the suspension assembly 150 further includes a stiffening plate 155. The reinforcing plate 155 is provided on the inner sidewall of the case 100, and corresponds to the position of the third fixing portion 1511. The reinforcing plate 155 has a plurality of coupling holes 1551. The plurality of connection holes 1551 correspond to the positions of the plurality of fixing holes 1514. Through the bolt penetrating each of the fixing holes 1514, the through holes on the case 100 corresponding to the positions of the fixing holes 1514, and the connection holes 1551 corresponding to the positions of the fixing holes 1514, the suspension assembly 150 can be fixedly connected with the case 100, thereby being beneficial to improving the connection strength between the case 100 and the suspension assembly 150. For example, the reinforcing plate 155 has three coupling holes 1551 corresponding to the positions of the three fixing holes 1514.

In some embodiments, the securing member 151 and the connecting member 152 are low carbon steel pieces, with a permanent fatigue limit of P0. When the suspension assembly 150 includes the damper 154, the maximum vibration amplitude of the air conditioning apparatus 1 is D1, and the stress value of the end portion of the connection member 152 is P1. When the suspension assembly 150 does not include the damper 154, the maximum vibration amplitude of the air conditioning apparatus 1 is D2, and the stress value of the end portion of the connection member 152 is P2. D1 < D2, and P1 < P0 < P2. It can be seen that the addition of shock absorbing members 154 to suspension assembly 150 effectively reduces stress at the ends of connecting members 152, thereby facilitating improved stability of suspension assembly 150. For example, D1 is 98 μm, D2 is 183.3 μm, P0 is 79.6MPa, P1 is 45.5MPa, and P2 is 83.6MPa.

In some embodiments, the mass of the air conditioning apparatus 1 is M, and when the suspension assembly 150 does not include the reinforcing plate 155, the third fixing portion 1511 is directly fixedly coupled with the sidewall of the case 100, and the maximum stress of the sidewall of the case 100 is P01. When the suspension assembly 150 includes the reinforcing plate 155, the reinforcing plate 155 is riveted to the side wall of the case 100, the third fixing portion 1511 is fixedly connected to the reinforcing plate 155, the maximum stress of the side wall of the case 100 is P02, and the maximum stress of the reinforcing plate 155 is P03. Wherein, (P02+P03) < P0 < P01. It can be seen that the addition of the reinforcing plate 155 to the suspension assembly 150 effectively reduces the maximum stress of the side walls of the case 100 and the reinforcing plate 155, thereby advantageously improving the reliability of the connection between the suspension assembly 150 and the case 100. For example, P01 is 111.8MPa, P02 is 10.4MPa, and P03 is 16.3MPa.

In some embodiments, as shown in fig. 28, the case 100 includes a first cover plate 103 and a second cover plate 104. The first cover 103 is a portion of the right side wall of the case 100 and is detachably connected to the top and bottom walls of the case 100. Opening the first cover plate 103 can expose the total heat exchanger core 500, the filter screen, and the drive mechanism 250 for cleaning and maintenance. The second cover 104 is a portion of the front side wall of the case 100 and is detachably connected to the top and bottom walls of the case 100. Opening the second cover 104 can expose the first fan 161, the second fan 162, the compressor 101 and the electronic expansion valve 102, which is convenient for cleaning and maintenance.

The electrical box 180 includes an electrical box cover 181, and the electrical box cover 181 is a side wall of the electrical box 180 far away from the box body 100 and is detachably connected with the electrical box 180. Opening the electric box cover 181 can expose a plurality of components and a plurality of circuits inside the electric box 180, thereby facilitating cleaning and maintenance.
