Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an air conditioner outdoor unit and an air conditioner having the same. Background Technology

[0002] PTAC (Packaged Terminal Air Conditioner) window units are the most commonly used cooling equipment in mid-to-high-end hotels and guesthouses in the US market. Installed within the wall, their indoor air outlets and control panels are located indoors, while another part extends outdoors, creating a "through-wall" structure. Correspondingly, through-wall holes are required in the wall. In North America, there are size restrictions on the through-wall holes; therefore, the corresponding air conditioner's length x width generally does not exceed 1068mm x 406mm.

[0003] Some hotels use multi-split air conditioning units, whose outdoor unit dimensions are designed to meet the installation requirements of PTAC window units and are installed using through-wall holes designed for PTAC installation. The outdoor unit includes a casing, an outdoor heat exchanger installed inside the casing, a fan, and a compressor, etc. Because the outdoor unit is installed through the through-wall holes, part of it is exposed indoors.

[0004] We now hope to integrate the fresh air system into the air conditioning unit. Utility Model Content

[0005] The primary objective of this invention is to provide an outdoor unit for an air conditioner that integrates a fresh air system, which not only avoids occupying the space of the indoor unit but also facilitates the connection between indoor and outdoor air intake and exhaust of return air.

[0006] The second objective of this invention is to provide an air conditioner that includes the aforementioned outdoor unit.

[0007] The first objective of this utility model is to provide an outdoor air conditioning unit, which includes a casing, an outdoor heat exchanger and an outdoor fan installed inside the casing. The casing has a main air duct, and the outdoor heat exchanger and the outdoor fan are installed in the main air duct. The outdoor air conditioning unit includes an indoor side and an outdoor side that are arranged opposite to each other in the inward and outward directions. The air inlet and air outlet of the main air duct are both located on the outdoor side. The indoor side has a fresh air inlet and a return air inlet. The outdoor air conditioning unit also includes a fresh air module, which has a fresh air channel and a return air channel. The inlet of the fresh air channel and the outlet of the return air channel are both connected to the main air duct. The outlet of the fresh air channel is connected to the fresh air inlet, and the return air inlet is connected to the inlet of the return air channel.

[0008] As can be seen from the above solutions, in the past, the fresh air module was installed in the indoor unit of the air conditioner. However, based on the feature that the outdoor unit of the air conditioner is installed through the wall hole, this utility model integrates the fresh air module into the outdoor unit of the air conditioner. This not only avoids occupying the space of the indoor unit of the air conditioner, but also matches the requirement of the fresh air module to connect the indoor and outdoor spaces through the wall hole. Furthermore, by directly adding the fresh air module to the outdoor unit of the air conditioner through the wall hole, the cumbersome procedures such as drilling a wall hole and connecting pipes, which were previously required when the fresh air module was installed in the indoor unit of the air conditioner, are eliminated.

[0009] A further design includes an inner wall on the indoor side of the unit, with the fresh air inlet and return air inlet located on the inner wall; the outdoor unit also includes a duct shell, which has a first channel and a second channel; from the outdoor side to the indoor side, the fresh air module, the duct shell, and the inner wall are arranged in sequence, with the fresh air channel, the first channel, and the fresh air inlet connected in sequence, and the return air inlet, the second channel, and the return air channel connected in sequence.

[0010] As can be seen from the above, it is better to place the fresh air module near the main air duct. However, with this setting, there is a certain distance between the fresh air module and the inner wall of the room. Therefore, a duct shell is set to connect the fresh air module with the fresh air inlet and the return air inlet to ensure the delivery of air supply and return.

[0011] Another further option is that the outdoor unit of the air conditioner includes an electrical box; the air duct shell is integrated into the body of the electrical box.

[0012] As can be seen from the above, this setup not only utilizes a suitable location on the indoor side to install the electrical box, but also integrates the air duct shell into the electrical box body, reducing the number of parts and lowering the assembly difficulty.

[0013] A further proposed solution is to include a compressor in the outdoor unit of the air conditioner. The compressor is located on the indoor side, and the compressor and the electrical box are respectively located on opposite sides of the width of the outdoor unit, which is perpendicular to the inward and outward directions.

[0014] As can be seen from the above, since most of the outdoor space is occupied by the outdoor heat exchanger and the outdoor fan, the compressor and electrical box are arranged on the indoor side along the width direction, so as to make more reasonable use of the indoor space and arrange the internal structure of the outdoor unit.

[0015] Another further option is to offset the fresh air inlet and return air inlet to the side in the width direction perpendicular to the inside and outside direction of the outdoor unit of the air conditioner; in the width direction, the air outlet and fan are located in the middle, the air inlet is offset to the side, and at least one air inlet is located on the same side as the fresh air module.

[0016] As can be seen from the above, the side-biased setting of the fresh air module in the width direction helps to avoid the outdoor heat exchanger. With the air inlet side-biased and the air outlet centered, the outdoor fan can pass through the side-biased fresh air module when it is working, ensuring the fresh air intake effect and the return air exhaust effect.

[0017] A further design involves providing air inlets on both opposite sides of the width; the casing includes an outer wall on the outdoor side, with the air inlets and outlets located on the outer wall; the outer wall and the outdoor heat exchanger surround the outdoor fan.

[0018] As can be seen from the above, since almost only the outer side wall of the outdoor fan installed in the wall penetration hole is exposed outside the wall, it is better to set both the air inlet and the air outlet on the outer side wall. Under this premise, the outdoor heat exchanger and the outer side wall surround the outdoor fan. For example, the outdoor heat exchanger is set in a "U" shape and faces the outdoor fan from three sides, while the flat outer side wall faces the outdoor fan from the fourth side, thus forming a surrounding effect. This setting can ensure that the incoming airflow passes through the outdoor heat exchanger and is then blown out by the outdoor fan, ensuring the heat exchange effect.

[0019] Another further solution is that the fresh air module includes a fresh air housing and a total heat exchange core, a fresh air fan blade, a return air fan blade, and a drive unit installed in the fresh air housing. The drive unit drives the fresh air fan blade and the return air fan blade to rotate coaxially. The total heat exchange core is provided with a first flow channel and a second flow channel. The fresh air channel passes through the fresh air fan blade and the first flow channel in sequence, and the return air channel passes through the return air fan blade and the second flow channel in sequence.

[0020] As can be seen from the above, this module can complete the delivery of fresh air and return air with a single drive unit. It is not only low in cost, but also compact in structure and occupies little space, thus providing greater feasibility for adding a fresh air module to the outdoor unit of an air conditioner.

[0021] Another further design is to include a chassis with a drainage channel on the chassis, where water flows from a higher position to a lower position, and an outdoor heat exchanger is positioned above the higher position.

[0022] A further solution would include a water pumping system with the pump inlet located at a low position.

[0023] As can be seen from the above, this setup ensures that the condensate dripping from the outdoor heat exchanger can reach the lower level through the drainage channel. Furthermore, the condensate at the lower level can be recovered and recycled using a pump system.

[0024] The second objective of this utility model is to provide an air conditioner that includes the aforementioned outdoor unit and indoor unit. Attached Figure Description

[0037] Air conditioner outdoor unit and air conditioner implementation examples See Figure 1 The air conditioner in this embodiment is a multi-split air conditioner, which includes an outdoor unit and at least two indoor units. A through-wall hole 900 for installing the PTAC (Packaged Terminal Air Conditioner) window unit is provided on the wall 9, and the outdoor unit of the air conditioner of this invention is installed through the through-wall hole 900.

[0038] See Figures 1 to 3 The figure shows a spatial rectangular coordinate system. The x-axis direction represents the inward and outward directions of the outdoor unit of the air conditioner in this utility model, the y-axis direction represents the width direction perpendicular to the outdoor unit of the air conditioner, the width direction and the inward and outward directions are both horizontal and perpendicular to each other, and the z-axis direction represents the vertical direction.

[0039] The outdoor unit of the air conditioner includes an outdoor side 108 and an indoor side 109 arranged opposite to each other in the direction of its own inward and outward. Specifically, the outdoor side 108 is the side exposed outdoors after the outdoor unit is installed in the predetermined accurate installation position on the wall penetration hole 900, and the indoor side 109 is the side exposed indoors after the outdoor unit is installed in the predetermined accurate installation position on the wall penetration hole 900.

[0040] See Figure 2 , Figure 3 and Figure 6 The outdoor unit of the air conditioner includes a housing 1. The housing 1 of this invention includes multiple outer and inner housing components. In this embodiment, the housing 1 includes an outer shell 11, a front shell 12, an inner shell 13, and a chassis 14. The outer shell 11 covers the outer end face of the outdoor side 108, and covers the entire outdoor side 108 and a portion of the upper, left, and right sides of the indoor side 109; the front shell 12 covers the inner end face of the indoor side 109 and another portion of the upper, left, and right sides of the indoor side 109. The outer end face of the outdoor side 108 and the inner end face of the indoor side 109 are the two opposing surfaces of the outdoor unit in the inward and outward directions. The outer end face of the outdoor side 108 faces outward in a horizontal direction, and the inner end face of the indoor side 109 faces inward in a horizontal direction. The chassis 14 is located at the bottom of the outdoor unit.

[0041] See Figures 2 to 4 The unit includes an outdoor heat exchanger 2, an outdoor fan 3, a compressor 4, and related pipes, an electrical box 5, a junction box 6, a water pump system 7, and a fresh air module 8, all housed within the casing 1.

[0042] In terms of the inward and outward directions, the outdoor heat exchanger 2, outdoor fan 3, and water pump system 7 are mainly located on the outer end face near the outdoor side 108, while the electrical box 5, compressor 4, junction box 6, and fresh air module 8 are located on the inner end face near the indoor side 109.

[0043] See Figure 2 , Figure 4 as well as Figure 5 The outer casing 11 includes an outer wall 18 disposed on the outer end face, on which an air inlet 101 and an air outlet 102 are disposed. Further, the two sets of air inlets 101 are disposed on opposite sides in the width direction, while the air outlet 102 is disposed in the middle in the width direction. An air duct 100 is disposed inside the outdoor unit of the air conditioner between the air inlets 101 and the air outlets 102, and the outdoor heat exchanger 2 and the outdoor fan 3 are both located in the air duct 100.

[0044] Furthermore, in the width direction, the outdoor fan 3 is located in the middle, and the "U"-shaped outdoor heat exchanger 2 faces the outdoor fan 3 from three directions other than the outward direction (the two width directions and the inward direction), while the outer wall 18 faces the outdoor fan 3 from the outward direction and is opposite to the exhaust side of the outdoor fan 3. In this way, the outer wall 18 and the outdoor heat exchanger 2 surround the outdoor fan 3; and the two air inlets 101 on both sides are located outside the width of the outdoor heat exchanger 2, while the air outlet 102 in the middle is opposite to the exhaust side of the outdoor fan 3. This arrangement can ensure that the incoming airflow passes through the outdoor heat exchanger 2 and is then blown out by the outdoor fan 3, thus ensuring the heat exchange effect.

[0045] Additionally, the outdoor heat exchanger 2 is fixedly mounted on the chassis 14 via the first connecting plate 21 and the second connecting plate 22, and the outdoor fan 3 is fixedly mounted on the chassis 14 via the bracket 31. Furthermore, both the air inlet 101 and the air outlet 102 are equipped with ventilation grilles. Additionally, the water pump 71 of the water pumping system 7 is positioned sideways towards the second width side 107.

[0046] See Figure 4 and Figure 6 In both the internal and external directions, the electrical box 5, compressor 4, and junction box 6 are all positioned close to the end face near the indoor side 108, and are arranged sequentially in a straight line from the first width side 106 to the second width side 107 along the width direction. That is, the compressor 4 of this invention is located on the indoor side 109, and in the width direction of the outdoor unit, the compressor 4 and the electrical box 5 are respectively located on opposite sides. The inner shell 13 is positioned between the outer shell 12 and the compressor 4.

[0047] Combination Figure 5 The fresh air module 8 is installed on the indoor side 109 and located in the main air duct 100. In the inward and outward direction, the fresh air module 8 is located between the outdoor heat exchanger 2 and the electrical box 5. In the width direction, the fresh air module 8 is set biased towards the first width side 106.

[0048] See Figure 7 The fresh air module 8 is an existing fresh air module. The fresh air module 8 includes a fresh air housing 80 and a total heat exchange core 86, a fresh air fan blade 83, a return air fan blade 84 and a dual-axis motor 85 disposed in the fresh air housing 80. The dual-axis motor 85 is the drive unit of this utility model.

[0049] A dual-axis motor 85 drives the fresh air fan blade 83 and the return air fan blade 84 to rotate coaxially and synchronously. The fan module composed of the dual-axis motor 85, the fresh air fan blade 83 and the return air fan blade 84 is located at the lower part of the fresh air casing 80. The total heat exchange core 86 is installed at the upper part of the fresh air casing 80. The total heat exchange core 86 has a first flow channel 861 and a second flow channel 862 that are independent of each other and have heat exchange effect.

[0050] The fresh air module 8 forms a fresh air channel 81 and a return air channel 82. The fresh air channel 81 passes through its inlet 811, fresh air fan blade 83, first flow channel 861 and its outlet 819 in sequence; the return air channel 82 passes through its inlet 821, return air fan blade 84, second flow channel 862 and its outlet 829 in sequence.

[0051] See Figure 6 , Figure 8 and Figure 9 The electrical box 5 includes a box body 51 and a circuit module 59 disposed within the electrical box 5. In this embodiment, in addition to providing an electrical space 503 for accommodating the circuit module 59, the box body 51 also integrates a duct shell. Specifically, the duct shell includes a first channel 501 and a second channel 502 disposed on the box body 51, outside the electrical space. The first channel 501 is disposed above the second channel 502, and both the first channel 501 and the second channel 502 are connected in the inward and outward directions. In the width direction, the first channel 501 and the second channel 502 are offset towards the first width side 106. In addition, the water pipe connector 49 of the water pump system 4 is disposed directly below the junction box 5.

[0052] See Figure 3 The faceplate 12 includes an inner wall 19 located on the inner end face of the indoor side 109. A fresh air inlet 103 and a return air inlet 104 are provided on the inner wall 19. The fresh air inlet 103 is located above the return air inlet 104. The fresh air inlet 103 and the return air inlet 104 are positioned to the side of the first width 106 in the width direction.

[0053] See Figure 7 and Figure 8 The inlet 811 of the fresh air duct 81 and the outlet 829 of the return air duct 82 are both connected to the main air duct 100. The outlet 819 of the fresh air duct 81 is connected to the fresh air inlet 103 through the first channel 501, and the return air inlet 104 is connected to the inlet 821 of the return air duct 82 through the second channel 502.

[0054] Previously, the fresh air module 8 was installed in the indoor unit of the air conditioner. This utility model is based on the outdoor unit of the air conditioner having a through-wall hole 900 (… Figure 1 (As shown) The installation features integrate the fresh air module 8 into the outdoor unit of the air conditioner, which not only avoids occupying the space of the indoor unit of the air conditioner, but also matches the requirement of the fresh air module 8 to connect the indoor and outdoor spaces through the wall hole 900. The fresh air module 8 can be directly added to the outdoor unit of the air conditioner through the wall hole 900, which also eliminates the cumbersome procedures such as drilling a wall hole and connecting pipes required by setting the fresh air module 8 in the indoor unit of the air conditioner in the past.

[0055] Furthermore, through the internal structural layout of the air conditioner outdoor unit, the size of the outdoor unit meets the 900mm requirement for the wall penetration hole, without occupying extra space.

[0056] Furthermore, it is preferable to position the fresh air module 8 close to the main air duct 100. However, this arrangement results in a certain distance between the fresh air module 8 and the inner wall 19 of the indoor side 109. The electrical box 5 is then placed in a suitable location within the indoor side 109, and the air duct shell is integrated onto the box body 51 of the electrical box 5, reducing the number of parts and simplifying the assembly process.

[0057] Furthermore, the fresh air module 8 can complete the delivery of fresh air and return air by working with a single dual-axis motor 85. This not only has a lower cost, but also a compact structure and small footprint, making it more feasible to add the fresh air module 8 to the outdoor unit of the air conditioner.

[0058] See Figure 5 as well as Figures 10 to 12 The housing 1 includes a chassis 14, on which a drainage channel 140 is provided. The drainage channel 140 includes a high position 1401 and a low position 1402, such as... Figure 12 As shown, there is a certain height difference between the high position 1401 and the low position 1402, and they extend in a slope. The outdoor heat exchanger 2 is set above the high position 1401. After the condensate from the outdoor heat exchanger 2 drips onto the high position 1401, the water in the drainage channel 140 flows from the high position 1401 to the low position 1402 of the drainage channel 140 and converges at the low position 1402. The water inlet of the water pump 41 of the pumping system 4 is set at the low position 1402. When the water level at the low position 1402 reaches the preset detection level, the water pump 41 starts and pumps the stored water out to be recycled, for example, for indoor atomization heat dissipation or heat exchanger reuse.

[0059] In other embodiments, the outdoor heat exchanger is configured in other forms, such as an "L"-shaped heat exchanger.

[0060] In other embodiments, the duct housing is separate from the electrical box housing.

[0061] In other embodiments, the fresh air module is located close to the inner wall (without a duct shell between them), the outlet of the fresh air channel of the fresh air module is directly connected to the fresh air inlet of the casing, and the return air inlet of the casing is directly connected to the inlet of the return air channel.

[0062] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
