Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a disinfection and purification system, a combined emergency and emergency air conditioning system, and an air conditioning unit. Background Technology

[0002] In recent years, frequent emergencies such as fires and epidemics have placed higher demands on the safety and reliability of building air systems. National regulations on building energy conservation, environmental protection, and emergency facilities (such as the "Code for Fire Protection Design of Buildings" and the "Code for Design of Infectious Disease Hospitals") have driven the development of air conditioning systems towards a "normal-emergency integration" approach. The application of technologies such as the Internet of Things and AI has provided a technological foundation for dynamic switching and intelligent control of systems. However, modern traditional air conditioning systems have significant limitations in transitioning between normal and emergency situations. Traditional air conditioning systems are primarily designed for daily temperature and humidity control and lack the ability to adapt to emergency scenarios (such as fire smoke extraction and epidemic air purification). Their functions are limited, and in emergencies such as fires and epidemics, ordinary air conditioners may be unable to quickly switch to smoke extraction or purification modes, leading to safety hazards or inefficiency and insufficient emergency response. In emergency modes, traditional systems may not operate efficiently, resulting in energy waste or functional failure.

[0003] Therefore, existing technologies have specifically proposed a combined normal / emergency air conditioning system. This system design ensures stable, reliable, and efficient operation under both normal and emergency conditions. Its core objective is to achieve flexible switching and coordinated operation between daily use and unexpected events (such as fires, epidemics, and extreme weather) through technological integration. Furthermore, traditional combined normal / emergency air conditioning systems for disinfection and purification have the following shortcomings:

[0004] High-temperature inactivation cannot be activated during high-efficiency filtration because it requires low airflow and the duct heating will affect the motor's operation. During this time, the system cannot purify, resulting in a purification vacuum period that affects the indoor air purification status. Utility Model Content

[0005] This invention provides a disinfection and purification system, a combined emergency and emergency air conditioning system, and an air conditioning unit to solve the problem that existing disinfection and purification systems cannot simultaneously operate high-efficiency filtration and high-temperature inactivation.

[0006] The technical solution of this utility model is a disinfection and purification system, comprising:

[0007] An adjacent but independent first air duct and a second air duct are arranged, and the first air duct and the second air duct form a common boundary through adjacent side walls; the air inlet of the first air duct and the air inlet and outlet of the second air duct are both connected to the room, and the air outlet of the first air duct is connected to the outside.

[0008] A spin filter that rotates along its center point passes through the common boundary and extends into both air ducts, forming independent filtration areas respectively; a high-temperature inactivation device is provided on the side of the filtration area in the first air duct facing away from its airflow direction.

[0009] The filtration area within the first air duct is configured such that all or part of the airflow in the first air duct is forced to pass through the filtration area.

[0010] The filtration area within the second air duct is configured such that all airflow in the second air duct is forced to pass through the filtration area.

[0011] Furthermore, the spin filter device includes a filter body rotatable about a central axis, the filter body being connected to the output end of the drive assembly;

[0012] The filter body achieves a spin motion around its center point through the drive component.

[0013] Furthermore, the sidewall of the first air duct forming the common boundary is recessed downward along the direction of the second air duct to form a groove structure, and the bottom end of the groove structure extends to the central axis of the spin filter device.

[0014] Furthermore, the high-temperature inactivation device is arranged in a grid or spiral pattern along the width of the first air duct.

[0015] Furthermore, a sealing element is filled between the outer wall of the spin filter device located in the second air duct and the corresponding inner wall of the second air duct. The sealing element is in close contact with the outer wall of the spin filter device and the inner wall of the second air duct to form a sealed connection, so that the airflow in the second air duct is forced to pass entirely through the spin filter device.

[0016] This utility model also proposes a combined emergency and emergency air conditioning system, including the disinfection and purification system described above.

[0017] The air inlet of the first air duct is equipped with an exhaust valve;

[0018] At least one filter device is provided on the side of the second air duct opposite to its airflow direction. A fresh air inlet is opened on the common boundary between the filter device and the air inlet of the second air duct. The fresh air inlet is in fluid communication with the air outlet of the first air duct. A fresh air valve is matched to the fresh air inlet.

[0019] A fan is installed on one side of the second air duct along its airflow direction.

[0020] Furthermore, the sidewalls of the first air duct and / or the second air duct away from the common boundary are provided with openings and corresponding sealing covers for the spin filter device, and the sealing covers are used to close the openings;

[0021] The spin filter can be moved from inside the duct to the outside through the opening, or from the outside into the duct through the opening.

[0022] Furthermore, the first air duct and / or the second air duct are provided with mounting bases corresponding to the side walls of the spin filter device, and the spin filter device is detachably connected to the mounting base through a slot and protrusion structure.

[0023] Furthermore, a heat exchange coil is provided between the fan and the spin filter device, which is used to cool or heat the airflow passing through it through heat exchange.

[0024] This utility model also proposes an air conditioning unit, which includes at least one emergency / normal air conditioning system as described above.

[0025] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0026] 1. This utility model extends a spin filter device through a common boundary into two air ducts simultaneously. A high-temperature inactivation device is then installed on the side of the filtration area in the first air duct facing away from the airflow direction, forming a high-temperature inactivation zone. The spin filter device in the second air duct forms a high-efficiency filtration zone, thereby separating the high-temperature inactivation zone from the high-efficiency filtration zone. This allows the disinfection and purification system to operate simultaneously for filtration and high-temperature inactivation, thus avoiding the problem of a vacuum period in air purification.

[0027] 2. When the gas temperature in the first air duct rises to the safe threshold, turn off the high-temperature inactivation device to avoid damage to the spin filter and fan due to excessive temperature. At this time, the residual heat of the high-temperature inactivation device can still form a hot airflow to inactivate and disinfect the spin filter. When the gas temperature in the first air duct drops to the inactivation set temperature, it indicates that the gas temperature in the first air duct has dropped below the safe threshold. At this time, the high-temperature inactivation device can be turned on again to avoid the situation where the spin filter cannot perform high-temperature inactivation while filtering, thus ensuring the cleanliness of the indoor air.

[0046] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0047] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0048] The existing technology for combined normal and emergency air conditioning refers to an air conditioning system design that can operate stably, reliably, and efficiently under both normal and emergency conditions. Its core objective is to achieve flexible switching and coordinated operation between daily use and emergencies (such as fires, epidemics, and extreme weather) through technological integration. However, traditional combined normal and emergency air conditioning systems for disinfection and purification have the following shortcomings:

[0049] High-temperature inactivation cannot be activated during filtration because it requires low airflow and the duct heating will affect the motor's operation. During this time, the system cannot purify, resulting in a purification vacuum period that affects the indoor air purification status.

[0050] Therefore, in some embodiments, such as Figure 1 As shown, this utility model proposes a disinfection and purification system capable of simultaneously operating filtration and high-temperature inactivation, comprising:

[0051] The first air duct 10 and the second air duct 20 are arranged adjacently and independently, and the first air duct 10 and the second air duct 20 form a common boundary through adjacent side walls; the air inlet of the first air duct 10 and the air inlet and outlet of the second air duct 20 are both connected to the room, and the air outlet of the first air duct 10 is connected to the outside.

[0052] A spin filter 30 that rotates along its center point passes through the common boundary and extends into both air ducts, forming independent filtration areas respectively; a high-temperature inactivation device 40 is provided on the side of the filtration area in the first air duct 10 facing away from its airflow direction.

[0053] The filtration area within the first air duct 10 is configured such that all or part of the airflow in the first air duct 10 is forced to pass through the filtration area.

[0054] The filtration area within the second air duct 20 is configured such that all airflow in the second air duct 20 is forced to pass through the filtration area.

[0055] It should be noted that this embodiment uses the example of the first air duct 10 preferably being an exhaust air duct (air is exhausted from indoors to outdoors) and the second air duct 20 preferably being a supply air duct (air is introduced from indoors or outdoors back into indoors); and in this embodiment, the first air duct 10 and the second air duct 20 are arranged side by side in the vertical direction, the air inlet of the first air duct 10 and the air outlet of the second air duct 20 are at the same end and adjacent, and the air outlet of the first air duct 10 and the air inlet of the second air duct 20 are at the same end and adjacent.

[0056] This embodiment also includes a main control unit, which is electrically connected to the spin filter device 30 and the high-temperature inactivation device 40.

[0057] Thus, when the disinfection and purification system needs to perform high-efficiency filtration and high-temperature inactivation at the same time, the main control unit will activate the high-temperature inactivation device 40 and the spin filter device 30, so that the high-temperature inactivation device 40 heats the airflow passing through it to the inactivation set temperature, and the spin filter device 30 rotates in place.

[0058] Then, indoor or outdoor air flows into the second air duct 20 and is filtered efficiently by the spin filter device 30 before being discharged into the room; at the same time, indoor air flows into the first air duct 10 and passes through the high-temperature inactivation device 40 and the spin filter device 30 in sequence. At this time, the airflow passes through the high-temperature inactivation device 40 to inactivate and kill viruses and bacteria and form a hot airflow (the temperature of the hot airflow reaches or exceeds the inactivation set temperature, the same throughout the text), and then flows to the spin filter device 30 to disinfect and inactivate it before being discharged to the outside.

[0059] Therefore, this utility model extends the spin filter device 30 through the common boundary into both air ducts simultaneously. Then, a high-temperature inactivation device 40 is provided on the side of the filtration area in the first air duct 10 away from its airflow direction to form a high-temperature inactivation zone. The spin filter device 30 in the second air duct 20 forms a high-efficiency filtration zone, thereby separating the high-temperature inactivation zone from the high-efficiency filtration zone. This allows the disinfection and purification system to operate filtration and high-temperature inactivation simultaneously, thus avoiding the problem of a vacuum period in air purification.

[0060] Furthermore, when the gas temperature in the first air duct 10 rises to a safe threshold (the safe threshold is greater than the inactivation set temperature), the main control unit will shut down the high-temperature inactivation device 40 to prevent damage to the spin filter device 30 due to excessive temperature. Of course, when the high-temperature inactivation device 40 shuts down due to excessive temperature, the residual heat of the high-temperature inactivation device 40 can still inactivate and disinfect viruses and bacteria in the passing airflow and form a hot airflow, which then flows to the spin filter device 30 in the first air duct 10 for inactivation and disinfecting. When the gas temperature in the first air duct 10 reaches the inactivation set temperature, it indicates that the gas temperature in the first air duct 10 has dropped below the safe threshold. At this time, the high-temperature inactivation device 40 can be reopened to raise the temperature, avoiding the situation where the spin filter device 30 cannot perform high-temperature inactivation while filtering, thus ensuring the cleanliness of the indoor air.

[0061] In some embodiments, to ensure that the spin filter device 30 can rotate around its center point, such as Figure 1 As shown, this embodiment proposes a structure for a spin filter device 30, comprising:

[0062] A filter body 301 that can rotate around a central axis, the filter body 301 being connected to the output end of the drive assembly;

[0063] The filter body 301 achieves a spin motion around its center point through the drive component.

[0064] It should be noted that the filter body 301 proposed in this embodiment is placed horizontally along the length of the air duct. The filter body 301 proposed in this embodiment is preferably cylindrical in shape; however, it can also be spherical or other near-cylindrical shapes, which are not limited here. Therefore, the center of mass of the filter body 301 coincides with its central axis, and the drive component is preferably a motor or a magnetic coupling device.

[0065] In some embodiments, to further ensure that the entire spin filter device 30 can undergo high-temperature inactivation and sterilization, such as Figure 5As shown, the sidewall of the first air duct 10 forming the common boundary is recessed downward along the direction of the second air duct 20 to form a groove structure 101, and the bottom end of the groove structure 101 extends to the central axis of the spin filter device 30.

[0066] It should be noted that the shape of the groove structure 101 proposed in this embodiment is preferably triangular, fan-shaped, conical, or other suitable shape, and is not limited here.

[0067] Thus, in this embodiment, the design of extending the bottom end of the groove structure 101 to the central axis of the spin filter device 30 allows the hot airflow that has been inactivated and sterilized by the high-temperature inactivation device 40 to reach the central axis of the spin filter device 30. The spin filter device 30 will rotate around its center point, so that both the inside and outside of the spin filter device 30 can rotate into the first air duct 10 and be passed through by the hot airflow, thus performing high-temperature inactivation and sterilization on the entire spin filter device 30.

[0068] Furthermore, the rotation speed of the spin filter device 30 can be adjusted according to actual needs. The higher the disinfection level selected by the user, the faster the rotation speed of the spin filter device 30; conversely, the slower the rotation speed.

[0069] Of course, in other embodiments, the sidewall of the entire first air duct 10 forming a common boundary is recessed downward along the direction of the second air duct 20 to form a groove structure 101, and the bottom end of the groove structure 101 extends to the central axis of the spin filter device 30, which is not limited here.

[0070] In some embodiments, the high-temperature inactivation device 40 is arranged in a grid or spiral pattern along the width direction of the first air duct 10.

[0071] It should be noted that the high-temperature inactivation device 40 proposed in this embodiment is composed of an electric heating wire. Of course, the high-temperature inactivation device 40 can also be selected with other heating structures according to the actual situation, which is not limited here.

[0072] This configuration enhances the heat exchange efficiency of the high-temperature inactivation device 40, ensuring that the air or airflow passing through the high-temperature inactivation device 40 is heated evenly and can reach the inactivation set temperature in a shorter time, thereby achieving the inactivation and sterilization of viruses and bacteria.

[0073] In some embodiments, to ensure that the air or airflow entering the second air duct 20 is highly filtered by the spin filter device 30 before being introduced into the room, thereby ensuring the cleanliness of the indoor air, such as... Figure 5As shown, a sealing element 201 is filled between the outer wall of the spin filter device 30 located in the second air duct 20 and the corresponding inner wall of the second air duct 20. The sealing element 201 is in close contact with the outer wall of the spin filter device 30 and the inner wall of the second air duct 20 to form a sealed connection, so that the airflow in the second air duct 20 is forced to pass entirely through the spin filter device 30.

[0074] It should be noted that the sealing element 201 proposed in this embodiment is made of rubber, silicone, or foam. Furthermore, the adjacent sidewalls of the first air duct 10 and the second air duct 20, which form a common boundary, are sealed with adhesive strips without affecting the rotation of the self-rotating filter device 30.

[0075] In some embodiments, such as Figure 2 As shown, this utility model also proposes a combined emergency and emergency air conditioning system, including the disinfection and purification system described above.

[0076] The air inlet of the first air duct 10 is equipped with an exhaust valve 50;

[0077] At least one filter device 60 is provided on the side of the second air duct 20 opposite to its airflow direction. A fresh air inlet is opened on the common boundary between the filter device 60 and the air inlet of the second air duct 20. The fresh air inlet is in fluid communication with the air outlet of the first air duct 10. A fresh air valve 70 is matched to the fresh air inlet.

[0078] A fan 80 is provided on one side of the second air duct 20 along its airflow direction.

[0079] It should be noted that the exhaust valve 50 and the fresh air valve 70 proposed in this embodiment are both electrically operated valves, which can receive control signals from the main control unit to open and close the valves.

[0080] The filter device 60 proposed in this embodiment adopts CEP plasma constant-efficiency purification technology. By breaking down air under high pressure, it generates plasma containing a variety of high-energy active substances such as positive ions, negative ions, electrons, and free radicals. These high-energy particles can directly destroy the cell membranes and DNA / RNA of bacteria and viruses, achieving efficient sterilization. At the same time, it can also effectively decompose gaseous pollutants such as formaldehyde. The spin filter device 30 adopts HEPA13 high-efficiency filtration, which is a passive physical filtration technology. The H13-level HEPA filter has a filtration efficiency of over 99.97% for 0.3-micron particles, and can effectively intercept solid pollutants such as dust, pollen, bacteria, and viruses. When used in combination with the filter device 60, it can form a synergistic purification system of "active killing + passive filtration".

[0081] The fan 80 proposed in this embodiment is a variable frequency fan using EC (electronic commutation) technology, which can perform variable frequency adjustment and dynamically regulate the air volume according to the control signal of the main control unit, thereby realizing intelligent exhaust or intake of fresh air.

[0082] The filter device 60 proposed in this embodiment operates in emergency situations and performs preliminary filtration of the air, followed by secondary filtration by the spin filter device 30.

[0083] Thus, when the combined emergency and emergency air conditioning system is in normal operation (“normal”), such as Figure 3 As shown, at this time, the main control unit will shut down the spin filter 30, the high-temperature inactivation device 40, the filter 60 (which can be activated when filtration is needed), and the exhaust valve 50. Then, it will open the fresh air valve 70. The operating frequency of the fan 80 will be set to the normal operating frequency f1. At this time, the air inlet of the first air duct 10 will act as the fresh air inlet, and the air inlet of the second air duct 20 will act as the return air inlet. Then, the fan 80 will draw in indoor air and outdoor fresh air, which will be filtered by the spin filter 30 before being introduced into the room.

[0084] When the combined normal and emergency air conditioning system switches to emergency mode ("emergency"), such as Figure 4 As shown, at this time, the main control unit closes the fresh air valve 70, starts the spin filter 30, the high-temperature inactivation device 40 and the filter 60, and opens the exhaust valve 50. Then, according to the disinfection level set by the user, the main control unit adjusts the rotation speed V1 of the spin filter 30. When the disinfection level is increased, the rotation speed V1 will be increased, and vice versa. The main control unit sets the operating frequency of the high-temperature inactivation device 40 to the set power P0. When the high-temperature inactivation device 40 reaches the set inactivation temperature in state P0, the fan 80 draws in the indoor air and introduces it into the room after passing through the filter 60 and the spin filter 30 for secondary filtration. At the same time, part of the air discharged into the room by the fan 80 will enter the first air duct 10 through the exhaust valve 50, and then pass through the high-temperature inactivation device 40 and the spin filter 30 before being discharged outdoors. The air in the first air duct 10 forms a hot airflow after passing through the high-temperature inactivation device 40, and then disinfects and inactivates the spin filter 30 in the first air duct 10.

[0085] Therefore, this utility model extends the spin filter device 30 through the common boundary into both air ducts simultaneously. Then, a high-temperature inactivation device 40 is provided on the side of the filtration area in the first air duct 10 away from its airflow direction to form a high-temperature inactivation zone. The spin filter device 30 and the filter device 60 in the second air duct 20 form a high-efficiency filtration zone, thereby separating the high-temperature inactivation zone from the high-efficiency filtration zone. This allows the combined emergency and emergency air conditioning system to operate filtration and high-temperature inactivation simultaneously, thus avoiding the problem of a vacuum period in air purification.

[0086] Furthermore, this embodiment achieves rapid response and emergency switching by controlling the start and stop status of the spin filter device 30, high-temperature inactivation device 40, exhaust valve 50, filter device 60, and fresh air valve 70.

[0087] Furthermore, when the gas temperature inside the first air duct 10 rises to a safe threshold, the main control unit will shut down the high-temperature inactivation device 40 to prevent damage to the spin filter device 30 and the fan 80 due to excessive temperature. Of course, when the high-temperature inactivation device 40 shuts down due to excessive temperature, its residual heat can still inactivate and disinfect viruses and bacteria in the passing airflow and form a hot airflow. When the gas temperature inside the first air duct 10 reaches the inactivation set temperature, it indicates that the gas temperature inside the first air duct 10 has dropped below the safe threshold. At this time, the high-temperature inactivation device 40 can be restarted to prevent the spin filter device 30 from failing to perform high-temperature inactivation while filtering, thus ensuring the cleanliness of the indoor air.

[0088] In other embodiments, a sealing structure can also be filled between the inner wall of the filter device 60 and the inner wall of the second air duct 20. The sealing structure is in close contact with the outer wall of the filter device 60 and the inner wall of the second air duct 20 to form a sealed connection, so that the airflow in the second air duct 20 is forced to pass through the filter device 60.

[0089] In some embodiments, to ensure modular installation of the spin-type filter device 30 in the combined day / night air conditioning system, facilitating maintenance and replacement, such as... Figure 6 As shown, the first air duct 10 and / or the second air duct 20 have openings and corresponding sealing covers 102 on the sidewalls away from the common boundary, corresponding to the spin filter device 30. The sealing covers 102 are used to close the openings.

[0090] The spin filter 30 can be moved from inside the air duct to the outside through the opening, or moved from the outside into the air duct through the opening.

[0091] It should be noted that, in this embodiment, an opening and a corresponding sealing cover plate 102 are provided on the side wall of the first air duct 10 away from the common boundary. The sealing cover plate 102 proposed in this embodiment is connected to the outer side wall of the corresponding first air duct 10 and / or second air duct 20 by means of a buckle or screw. Furthermore, the opening edge proposed in this embodiment is provided with a sealing gasket, and a sealing groove is provided at the corresponding position on the inner side of the sealing cover plate 102. The sealing gasket is embedded in the sealing groove to achieve a sealing seal between the sealing cover plate 102 and the opening.

[0092] In other embodiments (not shown in the figures), the first air duct 10 and / or the second air duct 20 are provided with mounting seats corresponding to the side wall of the spin filter device 30, and the spin filter device 30 is detachably connected to the mounting seats through a slot and a protrusion structure.

[0093] When the combined emergency and emergency air conditioning system does not need to use the spin filter 30 or when the spin filter 30 needs to be inspected, the maintenance personnel can first open the corresponding sealing cover 102, then remove the slot and protrusion structure on the spin filter 30 and the corresponding mounting base, and then move the spin filter 30 out of the air duct from the opening.

[0094] Of course, when the combined day and night air conditioning system requires the use of the spin filter 30, the maintenance personnel can move the fault-free spin filter 30 from the opening into the air duct, and then connect the slot and protrusion structure on the spin filter 30 to the corresponding mounting base. After the connection is completed, the maintenance personnel will seal the sealing cover 102 with the corresponding opening to complete the installation of the spin filter 30.

[0095] In some embodiments, such as Figure 2 As shown, a heat exchange coil 90 is also provided between the fan 80 and the spin filter device 30. The heat exchange coil 90 is used to cool or heat the airflow passing through it through heat exchange.

[0096] Thus, when the combined emergency and emergency air conditioning system is in normal operation ("normal"), the main control unit will shut down the spin filter 30, high-temperature inactivation device 40, filter 60 (which can be activated when filtration is needed), and exhaust valve 50. Then, it will open the fresh air valve 70, and the operating frequency of the fan 80 will be set to the normal operating frequency f1. At this time, the air inlet of the first air duct 10 will act as the fresh air inlet, and the air inlet of the second air duct 20 will act as the return air inlet. Then, the fan 80 will draw in indoor air and outdoor fresh air, which will be filtered by the spin filter 30 and then cooled or heated by the heat exchange coil 90 before being introduced into the room.

[0097] When the combined normal and emergency air conditioning system switches to emergency mode, the main control unit closes the fresh air valve 70, activates the spin filter 30, high-temperature inactivation device 40, and filter 60, and opens the exhaust valve 50. Then, according to the user-set disinfection level, the main control unit adjusts the rotation speed V1 of the spin filter 30; increasing the disinfection level raises V1, and decreasing it lowers it lowers. The main control unit sets the operating frequency of the high-temperature inactivation device 40 to the set power P0. When P0 reaches the set inactivation temperature, the fan 80 draws indoor air, which is then filtered twice by the filter 60 and the spin filter 30 before being cooled or heated by the heat exchange coil 90. The cooled or heated air is then introduced into the room. Simultaneously, some of the air exhausted by the fan 80 enters the first air duct 10 through the exhaust valve 50, then passes through the high-temperature inactivation device 40 and the spin filter 30 before being exhausted outdoors.

[0098] In other embodiments (not shown in the figure), a temperature sensor is installed at the air inlet of the second air duct 20. The temperature sensor is used to monitor the indoor temperature in real time and upload it to the main control unit. In this way, if the indoor temperature is too high, the main control unit will increase the flow rate of chilled water flowing into the heat exchange coil 90 to provide more cold air and cool the room.

[0099] In some embodiments, the present invention also provides an air conditioning unit, which includes at least one emergency / normal air conditioning system as described above.

[0100] It should be noted that the emergency air conditioning system proposed in this embodiment is independently installed in each room (such as a ward), with a compact structure, and switches between emergency and non-emergency operation through the modular installation of the self-rotating filter device 30.

[0101] When the combined emergency and emergency air conditioning system is in normal operation (“normal”), such as Figure 3 As shown, the spin filter 30 is removed from the air duct, and then the main control unit closes the high-temperature inactivation device 40, the exhaust valve 50 and the filter 60, and opens the fresh air valve 70. At this time, the second air duct 20 can perform return air temperature control, while the first air duct 10 can perform fresh air supply to ensure the comfortable indoor environment under normal circumstances.

[0102] When the combined normal and emergency air conditioning system is in an emergency ("emergency"), such as Figure 4As shown, the spin filter 30 is installed and reset into the air duct. Then, the main control unit starts the spin filter 30, the high-temperature inactivation device 40, and the filter 60, closes the fresh air valve 70, and opens the exhaust valve 50. The indoor air passes through the primary filtration of the filter 60 and the secondary filtration of the spin filter 30 in sequence, and then passes through the heat exchange coil 90 for cooling or heating. Then, most of the cooled or heated air is introduced into the room, and the remaining part enters the first air duct 10 through the exhaust valve 50. Then, it passes through the high-temperature inactivation device 40 and the spin filter 30 in sequence before being discharged outdoors. Among them, the air in the first air duct 10 forms a hot airflow after passing through the high-temperature inactivation device 40, and then disinfects and inactivates the spin filter 30 in the first air duct 10.
