Description

Technical Field

[0001] This utility model relates to the field of air handling technology, specifically to a combined air handling unit. Background Technology

[0002] Modular air handling units are mainly composed of basic functional sections such as a primary fresh air return section, a silencer section, a fan section, an exhaust section, a mixing section, a surface cooling water baffle section, a heating section, a humidification section, an intermediate section, a flow equalization section, a medium-efficiency filter section, an air supply section, and a rotary heat recovery section. Users can flexibly assemble these sections according to different usage requirements to meet the comfort needs of various locations.

[0003] Current modular air handling units are typically horizontal units, meaning that after air enters the unit, the airflow direction within the unit is roughly parallel to the ground or base. This has certain drawbacks: First, they occupy a larger area, especially horizontal modular air handling units with low to medium airflow rates. As the internal air ducts lengthen, the unit's footprint also increases.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Please see Figure 1 and Figure 2 One embodiment of this utility model provides a combined air handling unit, including: a housing 10, a primary filter 20, a high-efficiency filter 30, a fan assembly 40, and a heat exchange assembly 50.

[0035] The housing 10 has a first air duct 11 and a second air duct 12 arranged side by side. Both the first air duct 11 and the second air duct 12 extend in the vertical direction. The top of the first air duct 11 is provided with an air inlet 111 and the top of the second air duct 12 is provided with an air outlet 121. One side of the bottom end of the first air duct 11 and one side of the bottom end of the second air duct 12 are connected through a first ventilation opening.

[0036] The primary filter 20 and the fan assembly 40 are sequentially arranged in the first air duct 11 along the ventilation direction of the first air duct 11; the heat exchange assembly 50 and the high-efficiency filter 30 are sequentially arranged in the first air duct 11 along the ventilation direction of the second air duct 12, with the heat exchange assembly 50 located at the first vent.

[0037] The working principle of a combined air handling unit according to an embodiment of the present invention is explained below:

[0038] After the fan assembly 40 starts, the airflow enters the first air duct 11 through the air inlet 111, and then passes through the pre-filter 20. The airflow then passes through the fan assembly 40 and enters the second air duct 12 through the first vent. The airflow's temperature is regulated by the heat exchange assembly 50, and then it moves along the second air duct 12 to the high-efficiency filter 30. After passing through the high-efficiency filter 30, the airflow is blown out from the air outlet 121. The overall airflow direction is U-shaped, which helps to reduce the overall footprint of the unit, thereby saving installation space and costs.

[0039] The airflow can be filtered through the pre-filter 20 and the high-efficiency filter 30, resulting in good air quality.

[0040] It should be noted that the ventilation direction of the first air duct 11 refers to the direction of airflow from the air inlet 111 to the first vent after the fan assembly 40 is started, and the ventilation direction of the second air duct 12 refers to the direction of airflow from the first vent to the air outlet 121 after the fan assembly 40 is started.

[0041] The heat exchange component 50 is used to cool the airflow. It typically adopts a heat exchange coil structure, the structure and heat exchange principle of which are well known to those skilled in the art and will not be described in detail here.

[0042] The fan assembly 40 may be an EC fan, the specific structure of which is well known to those skilled in the art and will not be described in detail here.

[0043] In some alternative embodiments, the combined air handling unit further includes a heating assembly 60 disposed within the second air duct 12 and located between the heat exchange assembly 50 and the high-efficiency filter 30. The heating assembly 60 is used for auxiliary heating, thereby increasing the temperature of the airflow. In this embodiment, the heating assembly 60 employs multiple PTC heaters arranged side-by-side in a direction perpendicular to the ventilation direction of the second air duct 12. Of course, the heating assembly 60 may also employ heating structures based on other heating principles.

[0044] In some alternative embodiments, the combined air handling unit also includes a humidification assembly 70 disposed within the second air duct 12 and between the heat exchange assembly 50 and the high-efficiency filter 30. The humidification assembly 70 is used to increase the humidity of the airflow by spraying water toward the second air duct 12, thereby increasing humidity.

[0045] Please see Figure 3 and Figure 4 To facilitate the installation of the heating component 60 and the humidification component 70, in some optional embodiments, a support frame 13 is detachably provided in the second air duct 12. The support frame 13 is located between the heat exchange component 50 and the high-efficiency filter 30. The support frame 13 is provided with a second vent 131 and a support frame 132. The combined air handling unit also includes a heating component 60 and a humidification component 70. The heating component 60 is detachably provided at the second vent 131. The humidification component 70 includes a humidification nozzle 71 and a water storage and pressurization module 72. The humidification nozzle 71 is arranged on the support frame 132, which is used to support the humidification nozzle 71 in a suitable position. The heat exchange component 50 is detachably engaged with the support frame 13 and the housing 10. The support frame 13 can facilitate the disassembly and assembly of the heating component 60 and the humidification component 70, and can also be assembled with the heat exchange component 50. By tightly assembling multiple components together, the design of the support structure can be reduced, the stability of each component can be improved, and the integration can be higher.

[0046] In some optional embodiments, a water receiving tray 122 is detachably provided in the second air duct 12, a support frame 13 is located above the water receiving tray 122, a heat exchange component 50 is arranged on the water receiving tray 122 and located between the support frame 13 and the water receiving tray 122, a second vent 131 is correspondingly located above the water receiving tray 122, a humidifying nozzle 71 is correspondingly located above the second vent 131, and a water storage and pressurization module 72 is provided on the water receiving tray 122. Condensate on the heat exchange component 50 can drip onto the water receiving tray 122, and water may also drip when the humidifying nozzle 71 sprays water for humidification. The dripping water can fall from the second vent 131 and onto the water receiving tray 122, thus facilitating collection by the water receiving tray 122.

[0047] The water storage and pressurization module 72 is used to store water and to deliver the stored water to the humidification nozzle 71. The water storage and pressurization module 72 is usually equipped with a water pump or other structure to deliver the water. Of course, the humidification component 70 can also adopt other suitable structures, and is not limited to this example.

[0048] To facilitate the installation of the fan assembly 40, in some optional embodiments, a fan mounting frame 14 is detachably provided within the first air duct 11. The fan mounting frame 14 is located between the primary filter 20 and the first vent. A third vent 141 is formed on the fan mounting frame 14. The fan assembly 40 is detachably mounted on the fan mounting frame 14 and communicates with the third vent 141. After passing through the primary filter 20, the airflow passes through the third vent 141 and then enters the first vent. In this embodiment, a pressure equalization chamber 113 is formed within the first air duct 11, located between the fan mounting frame 14 and the second vent 131. After passing through the third vent 141, the airflow balances its pressure in the pressure equalization chamber 113 before entering the heat exchange assembly 50 within the second air duct 12 from the first vent, which helps to improve the uniformity of airflow temperature adjustment.

[0049] To facilitate the formation of the shell 10, in some optional embodiments, the shell 10 includes a frame 15, an insulation partition 16, and multiple insulation layers 17. The multiple insulation layers 17 are detachably mounted on the frame 15 and surround the frame 15 to form a cavity. The insulation partition 16 is disposed within the cavity and detachably engages with the frame 15, dividing the cavity into a first air duct 11 and a second air duct 12. A second vent 131 is formed between the bottom edge of the insulation partition 16 and the inner wall of the cavity. The frame 15 can also be assembled from multiple support beam structures, allowing the shell 10 to be disassembled into smaller structures, thus facilitating transportation.

[0050] In some optional embodiments, the support frame 13 is provided with a support portion 133 extending along the edge of the second vent 131. The bottom edge of the insulation partition 16 is detachably assembled with the support portion 133, and the support frame 13 can also provide support for the bottom of the insulation partition 16, which helps to improve the stability of the shell 10 structure. In this embodiment, the side of the support frame 13 is detachably engaged with the insulation layer 17.

[0051] To facilitate the assembly of the pre-filter 20 and the high-efficiency filter 30, in some optional embodiments, a first mounting frame 18 is detachably provided in the first air duct 11, and the pre-filter 20 is detachably mounted on the first mounting frame 18; a second mounting frame 19 is detachably provided in the second air duct 12, and the high-efficiency filter 30 is detachably mounted on the second mounting frame 19. In this embodiment, both the first mounting frame 18 and the second mounting frame 19 are designed with sliding rails, and the pre-filter 20 and the high-efficiency filter 30 slide into or out of the sliding rails, thereby facilitating assembly and disassembly.

[0052] In this embodiment, the frame 15, insulation partition 16, insulation layer 17, support frame 13, first mounting frame 18, second mounting frame 19, fan mounting frame 14, fan assembly 40, humidification assembly 70, heating assembly 60, pre-filter 20, high-efficiency filter 30, and drip tray 122 of the combined air handling unit are all detachable, thus facilitating packaging and transportation. It should be noted that the detachable structures can be achieved through screws, snap-fit ​​structures, pin structures, etc. In this embodiment, the detachable structure is mainly achieved through screws, such as between the frame 15 and the insulation partition 16, and between the support frame 13 and the insulation layer 17.

[0053] Modular air handling units achieve excellent air handling performance through a rational layout of their various functional structures. Furthermore, the U-shaped gas flow channel arrangement inside the unit helps save on ground installation space and effectively reduces transportation costs.
