Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0065] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0066] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0067] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0068] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0069] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0070] The combined air-conditioning unit is an air-handling device assembled from various air-handling functional sections. It includes a casing and multiple functional sections arranged in the casing, such as a heating section, a primary filtration section, a medium-efficiency filtration section, a sterilization section, and a heat recovery section. Different air-handling requirements can be achieved through the combination of different functional sections.

[0071] The outer shell of a conventional modular air-conditioning unit is connected and fixed by fasteners such as screws, which has low assembly efficiency and poor sealing, resulting in poor working performance of the air-conditioning unit.

[0072] refer to Figure 1-Figure 4 In order to solve the above problems, the casing of the combined air-conditioning unit proposed in the present application includes an outer frame 100, a heat insulating member 120 and a panel assembly 500.

[0073] The outer frame 100 includes a three-way adapter 300 and a side beam 110 . The three-way adapter 300 is disposed at a corner of the outer frame 100 , that is, at a corner of the outer frame 100 , and plays a role in fixing and connecting adjacent side beams 110 .

[0074] Specifically, a side beam 110 is respectively arranged at the corner position of the outer frame 100 along three mutually perpendicular directions XYZ, and the three-way adapter 300 connects and fixes the ends of the three side beams 110 at the corresponding corner positions, and the two ends of the side beam 110 are respectively connected to the three-way adapter 300.

[0075] Mounting positions are formed on the inner and outer sides of the side beam 110 for connecting the heat insulating member 120 .

[0076] The panel assembly 500 is disposed on the outer frame 100 . The panel assembly 500 includes an outer panel 510 and an inner panel 520 . The outer panel 510 is disposed on the outer side of the outer frame 100 , and the inner panel 520 is disposed on the inner side of the outer frame 100 .

[0077] A heat-insulating inner cavity is formed between the outer panel 510 and the inner panel 520 , and a heat-insulating layer is formed in the heat-insulating inner cavity. The heat-insulating inner cavity connects the outer panel 510 and the inner panel 520 into a whole, so as to improve the heat-insulating effect of the casing.

[0078] Specifically, the heat-insulating layer is a foaming material. After the outer frame 100 of the casing and the panel assembly 500 are installed, the heat-insulating inner cavity is filled with the foaming material to form the heat-insulating layer.

[0079] refer to Figure 5 , Figure 6 , Figure 8 , Fig. 9 as well as Fig.11 In some embodiments of the present application, the side beam 110 includes an outer supporting portion 111 and an inner supporting portion 112 , and two outer supporting surfaces 1111 and two inner supporting surfaces 1123 are formed on the outer supporting portion 111 .

[0080] In some embodiments of the present application, the cross-sectional shapes of the outer support portion 111 and the inner support portion 112 are both rectangular, the corners of the outer support portion 111 and the inner support portion 112 are connected, and the outer support portion 111 and the inner support portion 112 are integrally formed.

[0081] For example but not limited to, the cross-sectional shapes of the outer support portion 111 and the inner support portion 112 are both square, and the diagonals of the outer support portion 111 and the inner support portion 112 are arranged to overlap.

[0082] The outer supporting surfaces 1111 face the outside of the housing, and the outer mounting surfaces 1112 are respectively disposed adjacent to each outer supporting surface 1111 .

[0083] That is, the outer mounting surface 1112 is disposed adjacent to the inner supporting portion 112 .

[0084] An inner supporting surface 1123 and an inner mounting surface 1121 are formed on the inner supporting portion 112 . The inner supporting surface 1123 faces the inner side of the housing, and the inner mounting surface 1121 is disposed adjacent to the inner supporting surface 1123 .

[0085] The mounting position is formed between the inner mounting surface 1121 and the adjacent outer mounting surface 1112 .

[0086] The heat insulating member 120 specifically includes a main heat insulating portion 121 and a positioning portion 122 . The main heat insulating portion 121 is arranged in the installation position, and the positioning portion 122 is arranged on the outer side of the corresponding inner supporting portion 112 .

[0087] That is, the heat insulating member 120 is coated on the outer side of the inner supporting portion 112 .

[0088] In some embodiments of the present application, in order to reduce the use of fasteners such as fastening screws, the outer panel 510 and the inner panel 520 are connected to the outer frame 100 by plugging.

[0089] An outer bending portion extending inward is formed on the peripheral side of the outer panel 510 , and an outer plug-in groove 1211 is formed between the heat insulating member 120 and the outer mounting surface 1112 , and the outer bending portion is plugged into the outer plug-in groove 1211 .

[0090] The height of the outer bending portion is not greater than the depth of the outer plug-in slot portion 1211 , that is, the height of the outer bending portion is not greater than the height of the main heat insulating portion 121 .

[0091] In the installed state, the outer surface of the outer panel 510 is flush with the outer supporting surface 1111 of the outer supporting portion 111 .

[0092] In some embodiments of the present application, an inner bending portion extending outward is formed on the peripheral side of the inner panel 520 , an inner plug-in groove portion 1221 is formed on the inner side of the positioning portion 122 , and the inner bending portion is plugged into the corresponding inner plug-in groove portion 1221 .

[0093] The height of the inner bending portion is not greater than the depth of the inner plug-in groove portion 1221 , and thus, a heat-insulating inner cavity is formed between the outer panel 510 , the outer panel 510 and the heat insulating member 120 .

[0094] The inner side of the inner panel 520 and the outer panel 510 is sealed with foam glue by a glue dispenser, and is squeezed and sealed with the outer frame 100, thereby ensuring the overall sealing of the air conditioning box.

[0095] The combined air-conditioning unit has an outer frame 100 including a three-way adapter 300 and a side beam 110. The three-way adapter 300 is arranged at a corner of the outer frame 100 to connect and fix the ends of adjacent side beams 110, thereby reducing the use of fasteners such as screws. On the basis of meeting the connection strength, the integrity is better, the assembly efficiency is high, and the labor intensity is reduced.

[0096] An installation position is formed on the outer frame 100, and a heat insulating member 120 is fixed on the installation position. The heat insulating member 120 has a heat insulating effect and helps to seal the connection gap between the outer frame 100 and the panel assembly 500, thereby reducing the loss of cold and ensuring the working effect.

[0097] Combination Fig.11 , Fig.14 In order to reduce the overall mass of the outer frame 100, the outer support portion 111 is formed with a first through hole 1113 along its length direction, and the inner support portion 112 is formed with a second through hole 1122 along its length direction. A first connecting portion 310 and a second connecting portion 320 are formed on each adapter surface of the three-way adapter 300. The first connecting portion 310 is inserted into the first through hole 1113, and the second connecting portion 320 is inserted into the second through hole 1122.

[0098] The first through hole 1113 and the first connecting portion 310 , and the second through hole 1122 and the second connecting portion 320 are adapted in shape and size.

[0099] For example but not limited to, the first through hole 1113 and the second through hole 1122 are both rectangular long holes, and the corresponding cross-sectional shapes of the first connecting portion 310 and the second connecting portion 320 are also rectangular.

[0100] Parts of the first connection portion 310 and the second connection portion 320 are respectively inserted into the first through hole 1113 and the second through hole 1122 .

[0101] The single side beam 110 is connected and positioned with the three-way adapter 300 through two connecting parts, which can effectively improve the positioning performance, make the positioning more firm and accurate, and prevent relatively slight displacement.

[0102] refer to Fig.12 The material of the outer support portion 111 and / or the inner support portion 112 is glass fiber reinforced plastic or plastic. A reinforcing portion 113 is provided in the outer support portion 111 and / or the inner support portion 112 to improve the structural strength of the side beam 110 .

[0103] The reinforcement part 113 is specifically a steel plate or a square steel structure. During the forming process of the side beam 110, the steel plate and the square steel are directly embedded inside it, which helps to improve the structural strength of the side beam 110, prolong the service life, and is not prone to deformation and damage.

[0104] When the size of the air-conditioning box is too large, in order to meet the structural strength of the whole machine and facilitate the processing of the side beams 110 and the panel assembly 500, it is necessary to divide one surface of the casing into multiple areas, that is, to set multiple groups of panel assemblies 500 and side beams 110 on one surface of the casing.

[0105] refer to Figure 4 The multiple groups of panel assemblies 500 and the side beams 110 on the same surface of the casing are connected by weight, and the middle beam 200 is connected with the side beams 110 to strengthen the strength of the casing and play a role of auxiliary support.

[0106] There is at least one center beam 200 . On the outer frame 100 on which the center beam 200 is provided, a panel assembly 500 is provided between the center beam 200 and the side beams 110 parallel thereto in the same plane, or between adjacent center beams 200 .

[0107] That is, the panel assembly 500 is disposed between the center beam 200 and the adjacent side beams 110 , or the panel assembly 500 is disposed between adjacent center beams 200 .

[0108] Specifically, the two ends of the center beam 200 are fixed to the two opposite side beams 110 through intermediate connecting pieces, respectively, and the two ends of the center beam 200 are fixed to the side beams 110 connected thereto.

[0109] In some embodiments of the present application, in order to ensure that the supporting effect of the middle beam 200 on the outer frame 100 is bilaterally symmetrical, the cross-sectional shape of the middle beam 200 is set to be a herringbone shape.

[0111] The bottom surfaces of the two side support parts 220 are connected as one body, and a through middle passage 230 is formed between the two side support parts 220 .

[0112] In order to reduce the overall weight of the entire center beam 200 , a third channel 211 is formed in the middle support portion 210 , and a fourth channel 221 is formed in the side support portion 220 .

[0113] An upper supporting surface 213 is formed at the top of the middle supporting portion 210 , and upper mounting surfaces 212 are disposed on both sides of the middle supporting portion 210 .

[0114] A lower mounting surface 222 is formed on the outer side of the side support portion 220 , and the lower mounting surface 222 is disposed at an angle with the upper mounting surface 212 .

[0115] Installation positions are also formed between the two sides of the middle support portion 210 and the corresponding side support portion 220 , respectively. The main insulation portion 121 of the insulation member 120 is arranged in the installation position, and the positioning portion 122 is arranged on the outer side of the corresponding side support portion 220 .

[0116] That is, the main heat insulating portion 121 of the heat insulating member 120 is disposed in the installation position formed by the upper installation surface 212 and the lower installation surface 222 .

[0117] Similar to the side beam 110 , an outer plug-in groove 1211 is also formed between the middle support portion 210 and the main insulation portion 121 , the outer bending portion is plugged into the outer plug-in groove 1211 , and the outer panel 510 is flush with the outer side of the middle support portion 210 .

[0118] That is, the outer plug-in slot portion 1211 is formed between the upper mounting surface 212 and the main insulation portion 121 for connecting the outer panel 510 .

[0119] In the installed state, the outer surface of the outer panel 510 is flush with the upper support surface 213 of the middle support portion 210 .

[0120] An inner insertion groove 1221 is also formed on the heat insulating member 120 connected to the center beam 200 for connecting to the inner panel 520 at a corresponding position.

[0121] In order to reduce the overall weight of the center beam 200 , a third through hole is formed through the middle support portion 210 along its length direction, and a fourth through hole is formed through the side support portion 220 along its length direction.
