Description

Technical Field

[0001] This utility model relates to the field of fresh air dehumidification technology, and in particular to a liquid system fresh air unit and fresh air system. Background Technology

[0002] A liquid system fresh air handling unit is an air conditioning device that provides fresh air. It mainly works by drawing fresh air from the outside, processing it through dust removal, dehumidification (or humidification), and cooling (or heating), and then sending it indoors through a fan, replacing the original indoor air when it enters the indoor space.

[0003] Currently, existing commercial liquid system air handling units generally only contain one dehumidifying impeller, resulting in limited dehumidification effect and difficulty in meeting the needs of some situations with high air humidity requirements. Moreover, the design size of some existing commercial liquid system air handling units is usually large, making it difficult to transport the units via residential elevators. This causes many inconveniences for buildings equipped only with residential elevators when installing liquid system air handling units. Therefore, there is an urgent need for a smaller-sized liquid system air handling unit suitable for buildings equipped only with residential elevators to solve the above problems.

[0049] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0050] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0051] Currently available liquid system fresh air handling units generally integrate the unit's piping within the main body 1. The working principle of this type of liquid system fresh air handling unit is as follows: Figure 1 As shown, the liquid system fresh air handling unit's body 1 comprises a first layer and a second layer arranged from bottom to top. The first layer of body 1 houses a treatment fan 2, a regeneration fan 3, and a first refrigeration heat exchanger 8. The second layer of body 1 houses a first dehumidification impeller 4 and a first heating heat exchanger 10. Furthermore, a treatment filter component 6 is installed outside the first layer of body 1, and a regeneration filter component 7 is installed outside the second layer. The treatment adsorption airflow enters body 1 through the treatment filter component 6, passes through the first and second layers sequentially, and exits from body 1. The regeneration desorption airflow enters body 1 through the regeneration filter component 7, passes through the second and first layers sequentially, and exits from body 1. However, the dehumidification effect of this type of liquid system fresh air handling unit is limited and cannot meet the needs of situations requiring high humidity.

[0052] To improve the adsorption and dehumidification effect of commercial liquid system fresh air handling units, improvements were made to existing units. The working principle of the improved unit is as follows: Figure 2 As shown, the body 1 of the liquid system fresh air unit includes a first layer, a second layer, and a third layer arranged from bottom to top. The first layer of the body 1 is equipped with a treatment fan 2, a regeneration fan 3, and a first refrigeration heat exchanger 8. The second layer of the body 1 is equipped with a first dehumidification impeller 4 and a second refrigeration heat exchanger 9. The third layer of the body 1 is equipped with a second dehumidification impeller 5, a first heating heat exchanger 10, and a second heating heat exchanger 11. In addition, the first layer of the body 1 is also equipped with a treatment filter component 6, and the third layer of the body 1 is also equipped with a regeneration filter component 7. The treatment adsorption air path enters the body 1 through the treatment filter component 6, and exits from the body 1 after passing through the first layer, the second layer, and the third layer in sequence. The regeneration desorption air path enters the body 1 through the regeneration filter component 7, and exits from the body 1 after passing through the third layer, the second layer, and the first layer in sequence. Thus, the improved liquid system fresh air handling unit adds a third layer inside the main body 1, and a second dehumidifying impeller 5 is added to the third layer of the main body 1. The second dehumidifying impeller 5 further adsorbs and dehumidifies the air after it has been adsorbed and dehumidified by the first dehumidifying impeller 4, which can further reduce the humidity of the air to be treated, in order to meet the needs of some occasions with high air humidity requirements. However, the improved liquid system fresh air handling unit adds a third layer above the second layer of the main body 1 for installing the second dehumidifying impeller 5. At the same time, the addition of the second dehumidifying impeller 5 also makes the number and shape of the pipes for the adsorption air path and the regeneration desorption air path more complex. The more complex pipe structure and shape are installed inside the main body 1, making the size of the liquid system fresh air handling unit larger, which is difficult to transport by civil elevators. This poses many inconveniences for buildings that are only equipped with civil elevators when installing the liquid system fresh air handling unit.

[0053] To address the shortcomings of the improved liquid system fresh air handling unit mentioned above, referring to... Figures 3 to 11This utility model provides a liquid system fresh air handling unit, including a body 1 with a top and a bottom. The body 1 includes a first layer, a second layer, and a third layer from bottom to top. It also includes a treatment adsorption air path, a regeneration desorption air path, a treatment fan 2, a regeneration fan 3, a first dehumidification impeller 4, and a second dehumidification impeller 5. It may also include a treatment filter component 6 and / or a regeneration filter component 7, as well as a cooling component and a heating component.

[0054] Specifically, the air to be treated flows sequentially through the first, second and third layers of the body 1 via the treatment adsorption air path; that is, the air to be treated enters from the bottom of the body 1 and exits from the top of the body 1 within the treatment adsorption air path.

[0055] The regenerated air flows sequentially through the third, second, and first layers of the body 1 via the regeneration desorption air path; that is, the regenerated air enters from the top of the body 1 and exits from the bottom of the body 1 within the regeneration desorption air path.

[0056] The processing fan 2 is located on the processing adsorption air path of the first layer of the body 1. The processing fan 2 provides the driving force for the air to be treated to flow in the processing adsorption air path, so that the air to be treated can flow in the processing adsorption air path.

[0057] The regeneration fan 3 is located on the regeneration desorption air path of the first layer of the body 1. The regeneration fan 3 provides the driving force for the regeneration air to flow in the regeneration desorption air path, so that the regeneration air flows in the regeneration desorption air path.

[0058] The first dehumidification impeller 4 is located in the second layer of the body 1. The first dehumidification impeller 4 has a processing area and a regeneration area. The processing adsorption airflow flows through the processing area of ​​the first dehumidification impeller 4, which can dry and dehumidify the air to be processed. The regeneration desorption airflow flows through the regeneration area of ​​the first dehumidification impeller 4, which can desorb and regenerate the regeneration area of ​​the first dehumidification impeller 4.

[0059] The second dehumidification impeller 5 is located in the third layer of the body 1. The second dehumidification impeller 5 has a treatment zone and a regeneration zone. The treatment adsorption airflow flows through the treatment zone of the second dehumidification impeller 5, which can perform secondary drying and dehumidification on the air to be treated. The regeneration desorption airflow flows through the regeneration zone of the second dehumidification impeller 5, which can perform desorption and regeneration on the regeneration zone of the second dehumidification impeller 5.

[0060] The adsorption air path from the first layer to the second layer and from the second layer to the third layer are detachable and can be installed outside the body 1, and the regeneration desorption air path from the third layer to the second layer and from the second layer to the first layer are detachable and can be installed outside the body 1.

[0061] Therefore, this liquid system fresh air unit can achieve a stronger degree of air dehumidification, meeting the needs of some usage scenarios with higher air humidity. At the same time, the liquid system fresh air unit has detachable pipes for the adsorption and desorption regeneration air paths from the first floor to the second floor and from the second floor to the third floor of the unit 1, which are located outside the unit 1. Through reasonable layout, the number of pipes located inside the unit 1 is reduced, and the design size of the liquid system fresh air unit is reduced. This allows the unit 1 to be moved into a civil elevator for transportation. After being transported to the destination floor, the detachable pipes are then assembled back onto the unit 1. This solves the problem that some existing liquid system fresh air units are too large to fit into civil elevators. For buildings that are only equipped with civil elevators, the installation of liquid system fresh air units is more convenient and has greater practicality.

[0062] Furthermore, in existing liquid system fresh air handling units, the ductwork for the adsorption and regeneration desorption air paths is located inside the unit body 1. Due to the space requirements of the unit body 1, the internal duct layout is relatively compact, exacerbating the irregularities in the ductwork. This not only increases the manufacturing difficulty and mass production assembly challenges of the ductwork, but also leads to excessive air resistance within the ductwork, further hindering the flow of treated and regenerated air and resulting in higher energy consumption. Therefore, in this embodiment, the liquid system fresh air handling unit detachably places some of the ductwork for the adsorption and regeneration desorption air paths outside the unit body 1, making the ductwork structure more rounded. This not only reduces the manufacturing difficulty and simplifies mass production assembly, but also reduces the air resistance within the ductwork, allowing for smoother flow of treated and regenerated air within the unit body and lowering energy consumption.

[0063] In some alternative embodiments, refer to Figures 3 to 5 The liquid system fresh air handling unit includes a treatment filter element 6 and / or a regeneration filter element 7. The treatment filter element 6 is used to filter the air to be treated entering the treatment adsorption air path, and / or the regeneration filter element 7 is used to filter the regeneration air entering the regeneration desorption air path. Preferably, the treatment filter element 6 and / or the regeneration filter element 7 are pre-filters. The treatment filter element 6 is located upstream of the treatment fan 2 in the treatment adsorption air path to filter impurity particles in the air to be treated entering the treatment adsorption air path. The regeneration filter element 7 is located upstream of the second dehumidification impeller 5 in the regeneration desorption air path to filter impurity particles in the regeneration air entering the regeneration desorption air path.

[0064] In some alternative embodiments, refer to Figure 3 , Figure 5 , Figure 7 , Figure 10 and Figure 11The liquid system fresh air handling unit includes a refrigeration component, which is used at least to reduce the temperature of the air to be treated within the adsorption air path. Preferably, the refrigeration component includes a first refrigeration heat exchanger 8 and / or a second refrigeration heat exchanger 9. The first refrigeration heat exchanger 8 is disposed on the first layer of the unit body 1 and is used to reduce the temperature and humidity of the air to be treated entering the upstream processing area of ​​the first dehumidification impeller 4, thereby achieving cooling and dehumidification of the air to be treated while reducing the dehumidification pressure of the first dehumidification impeller 4. Alternatively, the second refrigeration heat exchanger 9 is disposed on the second layer of the unit body 1 and is used to reduce the temperature of the air to be treated after flowing through the processing area of ​​the first dehumidification impeller 4, thereby ensuring the dehumidification effect of the second dehumidification impeller 5 on the air to be treated.

[0065] It should be noted that the air to be treated has a certain temperature rise after flowing through the treatment zone of the first dehumidification rotor 4. The second refrigeration heat exchanger 9 can keep the air to be treated at a low temperature, ensuring the secondary dehumidification effect of the air to be treated as it passes through the second dehumidification rotor 5.

[0066] The liquid system fresh air handling unit includes a heating component for raising the temperature of the regenerated air in the regeneration desorption air path. Preferably, the heating component includes a first heat exchanger 10 and / or a second heat exchanger 11. The first heat exchanger 10 is located on the third layer of the unit body 1 and is used to raise the temperature of the regenerated air entering the upstream of the regeneration zone of the second dehumidification impeller 5, ensuring that the regenerated air temperature reaches the regeneration temperature of the second dehumidification impeller 5 and that the second dehumidification impeller 5 has better regeneration performance. Alternatively, the second heat exchanger 11 is located on the third layer of the unit body 1 and is used to raise the temperature of the regenerated air flowing through the regeneration zone of the second dehumidification impeller 5, ensuring that the regenerated air temperature after desorption and dehumidification of the second dehumidification impeller 5 reaches the regeneration temperature of the first dehumidification impeller 4 and that the first dehumidification impeller 4 has better regeneration performance.

[0067] It should be noted that the regenerated air experiences a certain temperature drop after flowing through the regeneration zone of the second dehumidifying rotor 5. The second heating heat exchanger 11 can heat the regenerated air to ensure the regeneration and desorption effect of the regenerated air on the first dehumidifying rotor 4.

[0068] In some alternative embodiments, refer to Figures 4 to 11The unit body 1 has a first connecting pipe 12 and a second connecting pipe 13 on one side. The first connecting pipe 12 is detachably connected at both ends to the processing areas of the processing fan 2 and the first dehumidifying impeller 4, respectively, extending the processing adsorption air path from the first layer to the second layer of the unit body 1. This connects the processing adsorption air paths of the first and second layers of the unit body 1. In practical applications, when a first refrigeration heat exchanger 8 is installed inside the unit body 1, the first refrigeration heat exchanger 8 can be located on the first layer of the unit body 1. One end of the first refrigeration heat exchanger 8 is connected to the processing fan 2, and the other end is connected to the first connecting pipe 12, placing the first refrigeration heat exchanger 8 downstream of the processing fan 2 and upstream of the first connecting pipe 12 on the processing adsorption air path to reduce the temperature and humidity of the air to be treated. The second connecting pipe 13 is detachably connected at both ends to the regeneration area of ​​the first dehumidifying impeller 4 and the regeneration fan 3, respectively, extending the regeneration desorption air path from the second layer to the first layer of the unit body 1. This connects the regeneration desorption air path of the second and first layers of the unit body 1. And / or,

[0069] On the other side of the main body 1, a third connecting pipe 14 and a fourth connecting pipe 15 are provided. The third connecting pipe 14 is detachably connected at both ends to the processing areas of the first dehumidifying impeller 4 and the second dehumidifying impeller 5, respectively, to extend the processing adsorption air path from the second layer to the third layer of the main body 1. This connects the processing adsorption air path of the second layer and the processing adsorption air path of the third layer of the main body 1. In practical applications, the second refrigeration heat exchanger 9 is located on the second layer of the main body 1. One end of the second refrigeration heat exchanger 9 is connected to the processing area of ​​the first dehumidifying impeller 4, and the other end of the second refrigeration heat exchanger 9 is connected to the processing area of ​​the second dehumidifying impeller 4. The other end of the second refrigeration heat exchanger 9 is connected to the third connecting pipe 14. That is, the second refrigeration heat exchanger 9 is positioned on the processing adsorption air path downstream of the first dehumidifying impeller 4 and upstream of the second dehumidifying impeller 5. The fourth connecting pipe 15 is detachably connected at both ends to the regeneration zone of the second dehumidifying impeller 5 and the regeneration zone of the first dehumidifying impeller 4, respectively, to extend the regeneration desorption air path from the third layer to the second layer of the body 1. This connects the regeneration desorption air path of the third layer of the body 1 with the regeneration desorption air path of the second layer. In practical applications, the second heating heat exchanger 11 is located on the third layer of the body 1. One end of the second heating heat exchanger 11 is connected to the regeneration zone of the second dehumidifying impeller 5, and the other end of the second heating heat exchanger 11 is connected to the fourth connecting pipe 15. That is, the second heating heat exchanger 11 is placed downstream of the second dehumidifying impeller 5 and upstream of the first dehumidifying impeller 4 on the regeneration desorption air path.

[0070] In addition, the first heating heat exchanger 10 is also located on the third layer of the body 1. One end of the first heating heat exchanger 10 is connected to the regeneration zone of the second dehumidification wheel 5, and the other end of the first heating heat exchanger 10 is connected to the regeneration filter component 7. That is, the first heating heat exchanger 10 is set in the regeneration desorption air path downstream of the regeneration filter component 7 and upstream of the second dehumidification wheel 5.

[0071] In this embodiment, refer to Figures 4 to 11 The body 1 includes a frame 101 and a housing 102 mounted on the frame 101. The housing 102 contains multiple plates of different sizes and can be mounted on the frame 101 by bolts or other components.

[0072] The first refrigeration heat exchanger 8 is connected to a first extension pipe 16 that passes through the housing 102 at one end. This allows the first connection pipe 12 to be installed on the housing 102 of the first layer of the body 1, so that it is connected to the first refrigeration heat exchanger 8 through the first extension pipe 16. In addition, the regeneration fan 3 is connected to a second connection pipe 13 that passes through the housing 102 at one end. This allows the second connection pipe 13 to be installed on the housing 102 of the first layer of the body 1, so that it is connected to the regeneration fan 3. The housing 102 of the first layer of the body 1 is provided with a channel for the first connection pipe 12 and the second connection pipe 13 to pass through, so that the first connection pipe 12 and the second connection pipe 13 can pass through the housing 102 of the second layer of the body 1 and be connected to the processing area of ​​the first dehumidification wheel 4 and the air inlet of the regeneration fan 3, respectively.

[0073] It should be noted that the first connecting pipe 12 and the second connecting pipe 13 have the same structure. One end of the first connecting pipe 12 and the second connecting pipe 13 is provided with a connecting flange. With the cooperation of bolts and other fasteners in the prior art, the first connecting pipe 12 and the second connecting pipe 13 can be installed on the shell 102 of the first layer of the machine body 1. At the same time, connecting pipe seats are provided on the air inlet side of the first dehumidifying impeller 4 processing area and the air outlet side of the regeneration area. The connecting pipe seats can be sealed and inserted with the first connecting pipe 12 and the second connecting pipe 13. When the other end of the first connecting pipe 12 and the second connecting pipe 13 passes through the channel on the shell 102, it can be sealed and inserted with the connecting pipe seat, realizing the connection between the first refrigeration heat exchanger 8 and the processing area of ​​the first dehumidifying impeller 4, as well as the connection between the regeneration area of ​​the first dehumidifying impeller 4 and the regeneration fan 3.

[0074] Therefore, when transporting the liquid system fresh air unit, the first connecting pipe 12 and the second connecting pipe 13 on one side of the unit body 1 can be removed, simplifying the internal structure of the liquid system fresh air unit and reducing its size, so that it can be transported by space-limited transport tools such as civil elevators, making the transportation process more convenient. After being transported to the destination, the first connecting pipe 12 and the second connecting pipe 13 can be reassembled on the unit body 1, which is easy to assemble.

[0075] The second refrigeration heat exchanger 9 is used to connect one end of the third connecting pipe 14 through the housing 102. The second dehumidification wheel 5 has a second extension pipe 17 installed on the side of the treatment area for connecting the third connecting pipe 14, which passes through the housing 102. This allows the third connecting pipe 14 to be installed on the housing 102 of the second and third layers of the machine body 1, so that it is connected to the second refrigeration heat exchanger 9 and connected to the second dehumidification wheel 5 through the second extension pipe 17.

[0076] The second heating heat exchanger 11 is used to connect one end of the fourth connecting pipe 15 through the housing 102. The first dehumidifying wheel 4 regeneration zone is used to connect one end of the fourth connecting pipe 15 with a fourth extension pipe 19 that passes through the housing 102. This allows the fourth connecting pipe 15 to be installed on the housing 102 of the second and third layers of the machine body 1, so that it is connected to the second heating heat exchanger 11 and connected to the first dehumidifying wheel 5 through the fourth extension pipe 19.
