Description

Technical Field

[0002] The existing hospital's building layout and air conditioning and ventilation system are designed and constructed according to the requirements of normal medical services. They cannot meet the requirements of "immediate" admission of epidemic patients in the event of an outbreak, and must be renovated (rebuilt) first.

[0003] Traditionally, hospitals typically use centralized dual-duct HVAC systems, which involve significant investment. Some newer products and patents propose setting up modular cabinets with different functional sections, dividing the air supply into dual channels for normal and emergency use. Air passes through HEPA filters during emergencies and not during normal times. However, these methods require a separate machine room to house the modular cabinets, resulting in a large footprint, and are only suitable for new construction projects.

Detailed Implementation

[0052] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0053] See Figures 1 to 8 According to an embodiment of the present invention, an air handling device is provided, comprising: a return air inlet 4; a fresh air inlet 6; an exhaust air inlet 1; a supply air outlet 15; a connecting cavity 600, wherein the connecting cavity 600 is connected to the return air inlet 4, the fresh air inlet 6, the exhaust air inlet 1, and the supply air outlet 15; and an adjusting component 5, wherein the adjusting component 5 is disposed within the connecting cavity 600, so as to control the flow rate of the airflow passing through the return air inlet 4, the fresh air inlet 6, the exhaust air inlet 1, and the supply air outlet 15 by adjusting the position of the adjusting component 5.

[0054] With the above configuration, the air handling equipment in this embodiment is equipped with multiple interfaces. After heat exchange treatment of fresh air or mixed air, it can further sterilize and filter, and the air handling channel can be switched by valves. Normally, it operates as a regular air conditioning system. In case of emergency, it can quickly switch control modes with one button to strictly ensure the cleanliness and safety of the treatment space with 100% fresh air, exhaust air, and filtration and sterilization modes. Alternatively, it can operate in mixed air energy-saving mode during inclement weather (without the risk of cross-infection). Moreover, it has a compact structure and can be concealed in the ceiling above the treatment room without the need for an additional machine room, thus solving the technical problem of large space occupation of hospital air conditioning systems in related technologies.

[0055] See Figures 1 to 4 In the air handling equipment of this embodiment, the air handling equipment includes: a first side plate 100, on which an exhaust vent 1 is disposed; a second side plate 200, on which an air supply vent 15 is disposed; a top plate 300, on which a fresh air vent 6 is disposed, one end of which is connected to the first side plate 100 and the other end of which is connected to the second side plate 200; and a bottom plate 400, on which a return air vent 4 is disposed, one end of which is connected to the first side plate 100 and the other end of which is connected to the second side plate 200.

[0056] In this way, the return air inlet 4, fresh air inlet 6, exhaust air outlet 1, and supply air outlet 15 are respectively set on four different sides, so that air enters and exits from the treatment equipment according to different working conditions, thereby simplifying the structure.

[0057] In the air handling equipment of this embodiment, see Figures 1 to 4 The air handling equipment further includes: a first partition 501, one end of which is connected to the top plate 300, and the other end of which is connected to the bottom plate 400; the connecting cavity 600 includes a first connecting cavity 601 disposed between the first partition 501 and the first side plate 100; and an exhaust fan 3 is disposed in the first connecting cavity 601.

[0058] By adopting the above settings, exhaust fan 3 is set up and activated during exhaust, thereby increasing exhaust efficiency.

[0059] See Figures 1 to 4In the air handling device of this embodiment, the air handling device further includes: a second partition 502, one end of the second partition 502 is connected to the top plate 300, and the other end of the second partition 502 is connected to the bottom plate 400; the connecting cavity 600 includes a second connecting cavity 602 disposed between the second partition 502 and the second side plate 200; and a blower 8 is disposed in the second connecting cavity 602.

[0060] By adopting the above settings, by setting up the supply fan 8, the exhaust fan 3 is started during exhaust, thereby increasing the exhaust efficiency.

[0061] In the air handling equipment of this embodiment, see Figures 1 to 4 The connecting cavity 600 includes a third connecting cavity 603 located between the first partition 501 and the second partition 502. The fresh air inlet 6 and the return air inlet 4 are both connected to the third connecting cavity 603. The adjusting component 5 is located inside the third connecting cavity 603.

[0062] With the above configuration, the adjustment component 5 is placed inside the third connecting cavity 603, between the first connecting cavity 601 and the second connecting cavity 602, thereby conveniently guiding the airflow passing through the surroundings.

[0063] See Figures 1 to 4 In the air handling device of this embodiment, the adjusting component 5 is rotatably arranged so as to guide the airflow in the third communicating cavity 603 by rotating the adjusting component 5.

[0064] With the above configuration, the airflow within the third communicating cavity 603 is guided by rotating the adjusting component 5. The structure is simple and the operation is convenient.

[0065] Specifically, the adjusting component 5 is a plate-shaped structure.

[0066] In the air handling equipment of this embodiment, see Figures 1 to 4 The air handling equipment includes a third side plate 700 and a fourth side plate 800, which are spaced apart from each other; the connecting cavity 600 is located between the third side plate 700 and the fourth side plate 800; one end of the adjusting component 5 is rotatably connected to the third side plate 700; and the other end of the adjusting component 5 is rotatably connected to the fourth side plate 800.

[0067] By using the above settings, the airflow passing through the regulating component 5 can be adjusted by controlling the rotation of the regulating component 5, so that the airflow flows in different directions, thereby achieving the effect of controlling the air volume entering and exiting from each air outlet.

[0068] See Figures 1 to 4In the air handling equipment of this embodiment, a first limiting block 301 is provided on the top plate 300, and a second limiting block 401 is provided on the bottom plate 400; the adjusting component 5 has a first adjusting position; when the adjusting component 5 is in the first adjusting position, one end of the adjusting component 5 abuts against the first limiting block 301, and the other end of the adjusting component 5 abuts against the second limiting block 401, so as to divide the third connecting cavity 603 into a first cavity 6031 and a second cavity 6032 that are not connected to each other. The first cavity 6031 is connected to the first connecting cavity 601, and the second cavity 6032 is connected to the second connecting cavity 602; the fresh air inlet 6 is located between the first limiting block 301 and the second partition 502; the return air inlet 4 is located between the second limiting block 401 and the first partition 501.

[0069] With the above configuration, when the adjusting component 5 is rotated so that it abuts against the first limiting block 301 and the second limiting block 401, the air duct is divided into an air inlet duct and a fresh air duct, allowing fresh air from the outside to enter the room to the maximum extent, while the air inside the room can also be exhausted to the maximum extent.

[0070] See Figures 1 to 4 In the air handling equipment of this embodiment, the air handling equipment further includes: a surface cooler 12, which is used for heat exchange with the airflow in the third communicating cavity 603, and the surface cooler 12 is located between the air supply fan 8 and the air outlet 15; and a water collection tray 13, which is located below the base plate 400 and below the surface cooler 12.

[0071] With the above configuration, fresh air, return air, or a mixture of fresh and return air are delivered by the supply fan 8 to the surface cooler 12 for heat exchange with chilled water, and then delivered to the room through the air outlet 15. This achieves the purpose of temperature regulation.

[0072] In the air handling equipment of this embodiment, see Figures 1 to 4 The air handling equipment further includes: a drive motor connected to the adjusting component 5 to drive the adjusting component 5 to rotate; and a control module connected to the drive motor, the control module controlling the angle of the adjusting component 5 according to the temperature of the airflow entering the return air inlet 4 and the temperature of the airflow entering the fresh air inlet 6.

[0073] With the above configuration, the fresh air and return air are mixed and then delivered to the surface cooler 12 by the air supply fan 8 to exchange heat with the chilled water, and then delivered to the room through the air supply outlet 15.

[0074] Specifically, the surface cooler 12 is provided with a condensate inlet 11, a surface cooler inlet 9, and a surface cooler outlet 10.

[0075] See Figures 1 to 8 In the air handling equipment of this embodiment, the air handling equipment further includes: an exhaust filter 2, disposed at the exhaust port 1, the exhaust filter 2 being detachably disposed; and / or, an air supply filter 7, the air supply filter 7 being disposed in the duct connecting the fresh air inlet 6 and the air supply port 15; and / or, the air supply filter 7 being disposed in the duct connecting the return air inlet 4 and the air supply port 15; and a sterilization and disinfection module 14, the sterilization and disinfection module 14 being disposed at the air supply port 15.

[0076] With the above-mentioned configuration, exhaust air filter 2 and supply air filter 7 can filter exhaust and supply air to control air cleanliness and safety. Additionally, the sterilization and disinfection module 14 (using plasma, electro-purification, etc.) disinfects and sterilizes the air supplied to the treatment space during an epidemic. The airflow channels can be switched via the device's air valves to adapt to different operating modes for handling fresh air, return air, and exhaust air. Furthermore, because the filtration and sterilization modules in the device meet the safety requirements for air cleanliness and bacterial count during emergencies (epidemics), this invention can quickly achieve emergency conversion between normal and emergency situations, responding to urgent needs at the fastest speed and providing a safe and reliable treatment space for society.

[0077] The treatment space in this embodiment includes an air handling unit, which is the air handling unit described above.

[0078] Specifically, traditional hospital air conditioning systems often share a single fan coil unit plus a fresh air system or a fan coil unit plus a full-air system across multiple wards. During an epidemic, because the return air system spans multiple wards, to minimize cross-infection among medical staff and patients, the return air system is shut down, and a 100% fresh air plus exhaust negative pressure control mode is adopted, significantly increasing the energy consumption of the air conditioning system. Furthermore, existing hospital air conditioning systems designed for both normal and emergency use typically require dual exhaust fans and dual ducts to differentiate between normal and emergency modes. This dual-duct design increases land use and initial investment, and requires significant time for construction (or modification), making it difficult to quickly respond to epidemic prevention and control needs and to admit patients as quickly as possible. Therefore, a device capable of rapidly switching between normal and emergency operating conditions and operating safely and stably is needed. This invention innovates on terminal air handling equipment for treatment spaces. The treatment space where the equipment is located can form an independent HVAC system, not sharing ventilation ducts with other wards, eliminating the risk of cross-infection. Therefore, during an epidemic, a 100% fresh air mode or a mixed-air energy-saving mode can be selectively used, depending on the severity of the epidemic and outdoor weather conditions.

[0079] This embodiment features an innovative terminal air handling unit for the treatment space. The treatment space equipped with this unit forms an independent HVAC system, independent of other wards' ventilation ducts, eliminating the risk of cross-infection. Therefore, during an epidemic, the unit can selectively use either a 100% fresh air mode or a mixed-air energy-saving mode, taking into account both the severity of the epidemic and outdoor weather conditions. Specifically, the air handling unit is equipped with multiple interfaces. After heat exchange treatment of the fresh or mixed air, it further sterilizes and filters it. Valves control the switching of the air handling channels. Normally, it operates as a regular air conditioning system; in emergencies, it can quickly switch control modes with a single button, using a 100% fresh air + exhaust + filtration and sterilization mode to strictly ensure the cleanliness and safety of the treatment space. Alternatively, it can operate in a mixed-air energy-saving mode during inclement weather (eliminating the risk of cross-infection). Its compact structure allows for concealed installation within the ceiling above the treatment room, eliminating the need for an additional machine room. Furthermore, this invention allows for selective, phased installation of modules according to the hospital's construction plan, reducing initial investment.

[0080] See Figures 1 to 8 In the treatment space of this embodiment, the treatment space includes multiple treatment rooms, and each of the multiple treatment rooms is equipped with the air handling equipment. The return air vent 4 and the supply air vent 15 of each of the air handling equipment are connected to the corresponding treatment room; and / or, the exhaust air vent 1 and the fresh air vent 6 of each of the air handling equipment are not connected to each other.

[0081] With the above setup, the treatment space where the air handling equipment is installed can be treated as an independent unit, without sharing ventilation ducts with other treatment spaces or wards, thus eliminating the risk of cross-infection.

[0082] This embodiment presents a rapidly convertible air conditioning system suitable for both normal and emergency use in medical spaces. After connecting the air ducts and chilled water pipes, the medical space where this system is installed can function as an independent processing unit, not sharing ventilation ducts with other medical spaces / wards, thus eliminating the risk of cross-infection. The equipment can operate energy-efficiently under normal conditions to meet the air conditioning needs of ordinary medical spaces. Furthermore, the air handling unit is equipped with multiple interfaces and can control the switching of air handling channels via valves. During an outbreak, the heat-exchanged air is further sterilized and filtered to meet air cleanliness and bacterial count requirements. This system can be installed within the ceiling of the medical space, without requiring additional machine room space. Moreover, some modules (such as the filtration module and disinfection module) do not need to be pre-installed under normal circumstances, reducing initial investment.

[0083] The air handling unit of this embodiment is equipped with an exhaust fan 3 and a supply fan 8. Air vents are provided in four directions: top, bottom, left, and right, namely a fresh air inlet 6, a return air inlet 4, an exhaust air inlet 1, and a supply air inlet 15. In addition, multiple functional modules can be installed in the unit, such as a high-efficiency filter module, a surface cooler module, and a sterilization and disinfection module 14. Overall, the air handling unit of this embodiment integrates multiple interfaces and various functional modules. One device can handle the temperature of fresh and return air, perform exhaust and supply air, and has a filtration module to filter the exhaust and supply air to control air cleanliness and safety. Furthermore, the sterilization and disinfection module 14 (using plasma, electro-purification, etc.) disinfects and sterilizes the air supplied to the treatment space during an epidemic. The air circulation channel can be switched and controlled by the air valve of the device to adapt to the treatment of fresh air, return air and exhaust air in different working modes. Since the filtration and sterilization modules in the device meet the safety requirements for air cleanliness and colony count in emergencies (epidemics), this utility model can quickly realize the conversion between normal and emergency treatment spaces, respond to emergency needs at the fastest speed, and provide a safe and reliable treatment space for society.

[0084] The specific working mode of this utility model patent is as follows:

[0085] Example 1:

[0086] Normal fresh air and return air operating modes: See Figure 5 Fresh air enters the equipment through fresh air inlet 6, and return air from the treatment space enters through return air inlet 4. Exhaust vent 1 is closed, exhaust fan 3 is not operating, and adjusting component 5 is tilted (not in contact with the baffles at the fresh air inlet and return air inlet). After the fresh air and return air mix, they are delivered by supply fan 8 to surface cooler 12 for heat exchange with chilled water, and then delivered to the room through supply air outlet 15. HEPA filters and sterilization modules are not required under normal circumstances to reduce equipment resistance.

[0087] Example 2:

[0088] Normal return air operating mode: See Figure 6 With exhaust vent 1 and fresh air vent 6 closed, exhaust fan 3 not operating, return air vent 4 open, and adjustment component 5 adjusted to a horizontal position, return air is delivered to the surface cooler 12 via supply fan 8. It then exchanges heat with chilled water through the surface cooler inlet 9 and outlet 10 before being delivered to the room via supply air vent 15. The high-efficiency filter and sterilization module are not required under normal circumstances to reduce equipment resistance. The operating effect of this mode is consistent with that of wall-mounted or floor-standing air conditioners installed in existing hospital treatment spaces, effectively bringing the indoor air to the set temperature. Fresh air is introduced into the room by opening the doors and windows of the treatment space.

[0089] Example 3:

[0090] Emergency fresh air plus exhaust mode: See Figure 7 Exhaust vent 1, return air vent 4, and fresh air vent 6 are all open. Exhaust fan 3 and supply fan 8 are both operating. Adjustment component 5 is adjusted to a vertical position and is tightly connected to the baffles of fresh air vent 6 and return air vent 4. Outdoor fresh air enters the equipment through fresh air vent 6, passes through supply air filter 7, and is then sent by supply fan 8 to surface cooler 12 for heat exchange with chilled water before being sent into the treatment space through supply air vent 15. Indoor return air enters the equipment through return air vent 4, passes through exhaust fan 3 and exhaust air filter 2, and is exhausted to the outside through exhaust vent 1.

[0091] Example 4:

[0092] Emergency and severe operating conditions: Fresh air plus return air working mode: See Figure 8 The system includes a high-efficiency filter and a sterilization module 14. Fresh air enters the equipment through the fresh air inlet 6, while return air from the treatment space enters through the return air inlet 4. The exhaust vent 1 is closed, the exhaust fan 3 is not operating, and the adjusting component 5 is tilted (not connected to the baffles at the fresh air inlet and return air inlet). After the fresh air and return air mix, they are delivered by the supply fan 8 to the surface cooler 12 for heat exchange with chilled water, and then delivered to the room through the supply air outlet 15. In severe cold and hot seasons, if a 100% fresh air plus exhaust air working mode is implemented, the temperature in the treatment space will deviate significantly from the human thermal comfort range, which is not conducive to the normal treatment work of doctors and patients, nor to the recovery of patients. Using this patented mode, indoor air can be sterilized and filtered to ensure the safety of people in the room, while also meeting the thermal comfort needs of people in the room.

[0093] The exhaust fan 3 and the supply fan 8 in the equipment can be frequency-controlled according to the indoor air exchange rate and negative pressure control requirements. They can operate at high power in emergencies to meet control requirements, and operate at low frequency in normal times, especially during transitional seasons, to save energy and reduce consumption.
