Description

Technical Field

[0001] This utility model relates to the field of air conditioning structure technology, and in particular to a fresh air conditioning structure. Background Technology

[0002] Fresh air systems are generally divided into central fresh air systems and distributed fresh air systems. Distributed fresh air systems can integrate air conditioning and fresh air, offering a higher overall cost-performance ratio, making them a research focus for many air conditioning manufacturers. However, existing distributed fresh air systems are inadequate in pre-treatment of fresh air, resulting in a temperature difference between the incoming fresh air and the indoor recirculated air from the air conditioner, leading to a poor user experience. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a fresh air conditioning structure that can reduce or even eliminate the temperature difference between fresh air and indoor circulating air of the air conditioner, ensure uniform outlet air temperature, and improve user experience.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A fresh air conditioning structure includes:

[0006] A ducted air handling unit, comprising a return air chamber and a heat exchange chamber, wherein the return air chamber and the heat exchange chamber are connected; a return air inlet is provided on the wall of the return air chamber, and an air outlet is provided on the wall of the heat exchange chamber;

[0007] The fresh air module is connected to the ducted air conditioner. The fresh air module has a fresh air inlet and a blower outlet. The fresh air module is used to draw in fresh air from the fresh air inlet and blow it out from the blower outlet. The blower outlet is connected to the return air chamber.

[0008] The fresh air ejected from the air outlet enters the return air chamber and is adapted to mix with the return air entering from the return air outlet. The mixed airflow is adapted to enter the heat exchange chamber and is finally discharged from the air outlet.

[0009] Furthermore, the fresh air module includes a fresh air fan and a filter, the inlet of the filter is the fresh air inlet, the outlet of the filter is connected to the inlet of the fresh air fan, and the outlet of the fresh air fan is the air outlet.

[0010] Furthermore, the filter has a built-in pre-filter and a medium-efficiency filter; the fresh air drawn in from the fresh air inlet is suitable for being filtered sequentially by the pre-filter and the medium-efficiency filter.

[0011] Furthermore, a fan assembly is provided in the return air cavity, the fan assembly including a drive component, a rotating shaft, and a duct fan; the drive component and the duct fan are both connected to the cavity wall of the return air cavity, the drive component is also adapted to be drivenly connected to the duct fan through the rotating shaft, and the outlet of the duct fan is connected to the heat exchange cavity.

[0012] Furthermore, there are three duct fans, the driving component is a motor body, the rotating shaft is a motor shaft, and all three duct fans are connected to the motor shaft.

[0013] Furthermore, a bracket is provided on the cavity wall of the return air chamber. The bracket is located close to the air outlet, and the drive component is located away from the air outlet. The rotating shaft is rotatably connected to the bracket, and the bracket does not block or completely block the fresh air thrown out by the air outlet.

[0014] Furthermore, the projection of the bracket on the surface where the air outlet is located coincides with the air outlet.

[0015] Furthermore, the projection portion of the bracket on the surface where the air outlet is located, which overlaps with the air outlet, has a grille.

[0016] Furthermore, the bracket is located between the air inlet of the duct fan closest to the air outlet and the air outlet, and is relatively closer to the air outlet; and / or, the bracket is only provided with fixing positions fixed to the cavity wall of the return air chamber on the two adjacent sides.

[0017] Furthermore, a heat exchanger is provided inside the heat exchange cavity, which divides the heat exchange cavity into a front heat exchange chamber and a rear heat exchange chamber. The mixed airflow entering the heat exchange cavity first reaches the front heat exchange chamber, then flows through the heat exchanger into the rear heat exchange chamber, and finally exits from the air outlet.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the fresh air module draws in fresh air from the fresh air inlet and throws it out from the air outlet. After the fresh air thrown out from the air outlet enters the return air chamber, it mixes with the return air entering from the return air inlet, so that the temperature between the fresh air and the return air tends to be the same. In this way, the temperature difference between the fresh air and the return air can be reduced or even eliminated, thereby ensuring the uniformity of the subsequent air outlet temperature and improving the user experience.

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1-5The diagram illustrates the structure of the new air conditioning system of this invention, which includes at least a ducted unit 1 and a fresh air module 2. The ducted unit 1 has a return air chamber 11 and a heat exchange chamber 12, which are connected. A return air inlet 111 is provided on the wall of the return air chamber 11, and an air outlet 121 is provided on the wall of the heat exchange chamber 12. Indoor air is suitable for entering the return air chamber 11 through the return air inlet 111; this portion of air entering the return air chamber 11 is called return air. The fresh air module 2 is connected to the ducted unit 1 and has a fresh air inlet 21 and a swivel outlet 22. The fresh air module 2 is used to draw in fresh air from the fresh air inlet 21 and swivel it out from the swivel outlet 22; the swivel outlet 22 is connected to the return air chamber 11. The fresh air ejected from the air ejector 22 enters the return air chamber 11 and is suitable for mixing with the return air entering from the return air port 111. The mixed airflow is suitable for entering the heat exchange chamber 12 and is finally discharged from the air outlet 121.

[0031] In actual use, the fresh air module 2 draws in fresh air through the fresh air inlet and throws it out through the air outlet 22. The fresh air thrown out through the air outlet 22 enters the return air chamber 11 and mixes with the return air entering through the return air inlet 111. At this time, heat exchange occurs between the fresh air and the return air, making their temperatures more similar. Then, the mixed airflow enters the heat exchange chamber 12 for heat exchange and is finally discharged from the air outlet 121. In the above process, the heat exchange between the fresh air and the return air in the return air chamber 11 can reduce or even eliminate the temperature difference between them, thereby ensuring the uniformity of the subsequent air outlet temperature and improving the user experience.

[0032] In some embodiments, the fresh air module 2 includes a fresh air fan and a filter (not shown). The filter inlet is a fresh air inlet 21, and the filter outlet is connected to the inlet of the fresh air fan. The outlet of the fresh air fan is a vent 22. By setting up the filter, the quality of the fresh air can be guaranteed. More specifically, the filter has a built-in pre-filter and a medium-efficiency filter; the fresh air drawn in from the fresh air inlet 21 is suitable for passing through the pre-filter and the medium-efficiency filter in sequence. Through two-stage filtration, the filtration effect can be improved, further enhancing the quality of the fresh air.

[0033] In some embodiments, a fan assembly is provided in the return air cavity 11. The fan assembly includes a drive component 31, a rotating shaft 32, and a duct fan 33. Both the drive component 31 and the duct fan 33 are connected to the cavity wall of the return air cavity 11. The drive component 31 is also adapted to be driven by the duct fan 33 through the rotating shaft 32. The outlet of the duct fan 33 is connected to the heat exchange cavity 12. The drive component 31 drives the duct fan 33 to operate through the rotating shaft 32, which can better mix the fresh air and return air, and also allow the mixed airflow to enter the heat exchange cavity 12 more smoothly.

[0034] In some embodiments, there are three duct fans 33. The drive component 31 is the motor body, and the rotating shaft 32 is the motor shaft. All three duct fans 33 are connected to the motor shaft. In the above arrangement, the rotating shaft 32 is supported by the drive component 31. By setting three duct fans 33, the mixing effect of fresh air and return air can be further improved, and better power can be provided for airflow.

[0035] In some embodiments, a bracket 34 is further provided on the cavity wall of the return air chamber 11. The bracket 34 is located near the air outlet 22, and the drive member 31 is located away from the air outlet 22. The rotating shaft 32 is rotatably connected to the bracket 34, and the bracket 34 does not obstruct or completely obstructs the fresh air ejected from the air outlet 22. In the above arrangement, the rotating shaft 32 is supported by both the drive member 31 and the bracket 34, and the drive member 31 and the bracket 34 are basically located at both ends of the rotating shaft 32. This provides more reliable support for the rotating shaft 32 and ensures the reliability of the rotating shaft 32 during rotation. In addition, in the above arrangement, the bracket 34 does not obstruct or completely obstruct the fresh air ejected from the air outlet 22, which reduces the obstruction to the fresh air ejected from the air outlet 22 and ensures smooth airflow.

[0036] The bracket 34 can prevent the fresh air from being thrown out of the air outlet 22 from being blocked by the following method: the bracket 34 and the air outlet 22 are offset from each other in the air outlet direction of the air outlet 22. This offset should be understood as the projection of the bracket 34 on the air outlet 22 along the air outlet direction of the air outlet 22 having no overlap with the air outlet 22. In this way, it can be ensured that the bracket 34 does not block the fresh air thrown out of the air outlet 22.

[0037] The bracket 34 can partially block the fresh air ejected from the air outlet 22 in the following three ways: 1. The bracket 34 and the air outlet 22 are partially offset in the air outlet direction of the air outlet 22, that is, the projection of the bracket 34 on the surface of the air outlet 22 coincides with the air outlet 22, or partially coincides. 2. The projection of the bracket 34 on the air outlet 22 along the air outlet direction coincides with the air outlet 22, but a grille 341 is provided on the bracket 34. 3. The projection of the bracket 34 on the surface of the air outlet 22 coincides with the air outlet 22, and a grille 341 is provided on the overlapping part. All of the above methods can achieve the goal of the bracket 34 not completely blocking the fresh air ejected from the air outlet 22.

[0038] It should be noted that in actual product manufacturing, due to considerations of the internal space of the return air cavity 11 or the need to avoid other components, it may be necessary to place the bracket 34 on the air path of the air outlet 22. In this case, simply setting a grille 341 on the bracket 34 can reduce the obstruction of the fresh air thrown out of the air outlet 22.

[0039] In some embodiments, the bracket 34 is detachably connected to the cavity wall of the return air chamber 11. This facilitates assembly, production, maintenance, and replacement. Specifically, the bracket 34 and the cavity wall of the return air chamber 11 can be connected using existing detachable connection methods such as screws or snap-fits.

[0040] In some embodiments, a heat exchanger 41 is provided inside the heat exchange chamber 12, dividing the heat exchange chamber 12 into a front heat exchange chamber 122 and a rear heat exchange chamber 123. The mixed airflow entering the heat exchange chamber 12 first reaches the front heat exchange chamber, then flows through the heat exchanger 41 into the rear heat exchange chamber 123, and finally exits from the air outlet 121. In this way, sufficient heat exchange can be ensured between the mixed airflow and the heat exchanger 41, preventing unexchanged mixed airflow from being directly discharged from the air outlet 121.

[0041] In some embodiments, the bracket 34 is located between the air inlet of the duct fan 3 closest to the air outlet 22 and the air outlet 22, and is relatively closer to the air outlet 22; for ease of understanding, please refer to Figure 6 In the figure, L1 is the distance between the bracket 34 and the air outlet 22, and L2 is the distance between the bracket 34 and the air inlet of the duct fan 33 closest to the air outlet 22. L1 is less than L2. Thus, since the fresh air module 2 is used less frequently, while the duct fan 33 is used more frequently, this setting is more reasonable.

[0042] In some embodiments, the bracket 34 is provided only on the two adjacent sides for fixing to the cavity wall of the return air cavity 11. For ease of understanding, please refer to... Figure 7 In the figure, the first side 342 and the second side 343 of the bracket are the two sides of the bracket 34 that are adjacent to each other, and fixed positions are provided on these two sides; or the cavity wall of the return air cavity 11 is only provided with fixed positions on the adjacent inner cavity walls to connect with the bracket 34, so that the bracket can minimize or completely block the air outlet.

[0043] In some embodiments, the ducted air conditioner 1 is provided with an air guide plate at the air outlet 121. The air guide plate can be used to adjust the air outlet 121, improving ease of use.

[0044] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
