Description

Technical Field

[0001] This invention relates to an outdoor air conditioning system and method with waste heat recovery, and more particularly to a system with heat recovery application and energy saving and carbon reduction efficiency, applicable to places or factories in the semiconductor, electronics, biotechnology, food processing, and precision instrument manufacturing fields. Background Technology

[0002] Semiconductor manufacturing requires four major exhaust systems: acid exhaust, alkali exhaust, volatile organic compound exhaust, and general exhaust. Therefore, a large amount of outside air must be supplied to meet the exhaust requirements.

[0003] In the semiconductor industry, the external air conditioning unit (MAU) in the plant system is an energy-intensive but necessary piece of equipment, and the energy consumption of an external air conditioning unit in a current process plant can be as high as 10,000 refrigeration tons.

[0004] In recent years, in order to achieve the goal of energy conservation and carbon reduction, the semiconductor industry has been actively seeking improvement solutions for high-energy-consuming equipment or facilities in the factory in order to reduce energy consumption. Among them, the external air conditioning unit (MAU) is a key piece of equipment to be improved.

[0005] Therefore, in view of the above-mentioned shortcomings, the inventors aim to propose an outdoor air conditioning system and method with waste heat recovery, which has the functions of heat recovery application and energy saving and carbon reduction, and is easy for users to operate and assemble. The inventors have devoted themselves to research, design and assembly to provide convenience for users, which is the purpose of the invention. Summary of the Invention

[0006] In view of this, the present invention provides an outdoor air conditioning system and method with waste heat recovery, in order to at least partially solve the above-mentioned technical problems.

[0007] The main objective of this invention is to provide an outdoor air conditioning system and method with waste heat recovery. This system primarily utilizes a combination design of an outside air unit, an outside air conditioning system, a first heat exchanger, a water tank, a second heat exchanger, an incineration unit, and a duct. This design enables the use of waste heat discharged from the incineration unit to supply the dehumidifying impeller of the outside air conditioning system, removing the latent heat of the outside air. The waste heat is then transported to the desired location via the duct. Therefore, this system offers heat recovery and energy-saving / carbon-reduction benefits, while also reducing energy costs and increasing overall practicality.

[0008] Another objective of this invention is to provide an outdoor air conditioning system and method with waste heat recovery. The outdoor air conditioning system includes a housing, and a dehumidifying impeller is disposed within the housing. The dehumidifying impeller has a processing area and a regeneration area. At least one first filter device, at least one first temperature device, at least one water washing device, and at least one second temperature device are designed in front of the dehumidifying impeller, so that the outside air can first pass through the above-mentioned devices for dust removal, filtration, and temperature and humidity control, and then be delivered to the processing area of ​​the dehumidifying impeller for dehumidification and adsorption. A fan is provided in the housing, which is located either in front of or behind the dehumidifying impeller, so as to push and pull the outside air to move, thereby generating fresh air with constant temperature and humidity, and increasing the overall usability.

[0009] Another objective of this invention is to provide an external air conditioning system and method with waste heat recovery. The system is connected to at least one cleanroom, at least one ward, at least one food processing area, at least one semiconductor manufacturing plant, and at least one electronic manufacturing plant via a duct. This allows the system to provide the large amount of external air needed to replenish the aforementioned locations, and to circulate the airflow within these locations to remove dust and heat, thereby achieving the required cleanliness and ventilation, and replacing the existing air, thus increasing overall operability.

[0055] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the invention for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0056] Figures 1-3 The diagram is a schematic diagram of an embodiment of the present invention. The preferred embodiment of the external air conditioning system and method with waste heat recovery of the present invention is applicable to places or factories related to the semiconductor field, electronic technology field, biotechnology field, food processing field, precision instrument manufacturing field, etc., mainly because it has the functions of heat recovery application and energy saving and carbon reduction.

[0057] The outdoor air conditioning system with waste heat recovery of the present invention is mainly achieved through a combination design of an outside air unit 10, an outside air conditioning system 20, a first heat exchanger 30, a water tank 40, a second heat exchanger 50, an incineration device 60, and a duct 70 (e.g., Figure 1 and Figure 2 As shown), the outside air 10 contains at least one gas or combination thereof, mainly a mixture of 78.1% nitrogen, 21% oxygen, 0.9% argon and other impurities. The outside air 10 is also commonly known as air. Furthermore, the incineration equipment 60 is any one of a direct-fired incinerator (TO), a catalytic incinerator (not shown), or a regenerative thermal oxidizer (RTO) (not shown). When the incineration equipment 60 is a direct-fired incinerator (TO), it is equipped with any one of two, three, or four heat exchangers 62. The incineration equipment 60 is combined with any one of a dual-rotor volatile organic compound (VOC) treatment system (not shown) or a single-rotor volatile organic compound (VOC) treatment system (not shown), and the incineration equipment 60 discharges a combustion exhaust gas 61 (such as...). Figure 1 and Figure 2As shown), the combustion exhaust gas 61 has a temperature exceeding 150°C.

[0058] The outdoor air conditioning system 20 includes a housing 21 with an outdoor air inlet 211 for the entry of outdoor air 10. The housing 21 of the outdoor air conditioning system 20 is internally designed with at least one first filter device 22, at least one first temperature device 23, at least one water washing device 24, a dehumidifying impeller 25, and at least one second temperature device 26 (e.g., ...). Figure 1 and Figure 2 As shown), the dehumidifying rotor 25 is a special honeycomb-shaped paper rotor carrying a desiccant. Because the honeycomb pore size is only 1.5mm, it can achieve a 1m... 3 The rotary paper core has a moisture absorption area of ​​3000m². 2 Airflow through the honeycomb-shaped channels is in a boundary laminar flow state, resulting in good moisture exchange and strong dehumidification capacity. The dehumidification impeller 25 has a treatment zone 251 and a regeneration zone 252. The first heat exchanger 30 is connected to the regeneration zone 252 and provides a heat source to the regeneration zone 252 for desorption. The first heat exchanger 30 receives a gas, which can be either outside air or gas treated in the treatment zone (not shown), for heat exchange. The water tank 40 is connected to the first heat exchanger 30 and the second heat exchanger 50 (e.g.,...). Figure 1 and Figure 2 As shown, the water tank 40 outputs water, which can be any one of filtered water, tap water, cooling water, or chilled water. The water in the water tank 40 transfers heat from the second heat exchanger 50 to the first heat exchanger 30. The water tank 40 is connected to a pump 42 to propel the water in, and the water tank 40 is equipped with a water valve 41 to control the water entering the water tank 40, thus providing a water supply. Both the first heat exchanger 30 and the second heat exchanger 50 are liquid-to-gas heat exchangers.

[0059] Furthermore, the incineration equipment 60 discharges a combustion exhaust gas 61, which has a temperature exceeding 150°C, and the combustion exhaust gas 61 passes through the second heat exchanger 50 (e.g., Figure 1 and Figure 2As shown, the water and gas in the second heat exchanger 50 exchange heat, allowing the water in the water tank 40 to transfer heat to the first heat exchanger 30 for use. The water and gas in the first heat exchanger 30 then exchange heat again, delivering the heat-generating gas to the regeneration zone 252 for thermal desorption. The desorbed gas is then discharged to the outside, which could be either the sky or the chimney 90. The combustion exhaust gas 61, after heat exchange in the second heat exchanger 50, is then delivered to the chimney 90 for emission.

[0060] The dehumidifying impeller 25 is further designed with at least one first filter device 22, at least one first temperature device 23, and at least one washing device 24. The at least one first filter device 22 is any one or a combination of a pre-filter or a medium efficiency filter. The pre-filter is mostly plate-shaped, suitable for primary filtration, mainly used to filter dust particles larger than 5μm, and its materials are mainly non-woven fabric, nylon mesh, activated carbon filter media, and metal mesh. The medium efficiency filter is mostly bag-shaped, widely used for intermediate filtration, mainly used to filter dust particles larger than 1-5μm, and its materials are mainly synthetic fibers and non-woven fabric. The at least one first temperature device 23 is any one or a combination of a pre-cooling coil 231 and a preheating coil 232 (e.g., Figure 2 As shown), the precooling coil 231 is supplied with either cooling water or ice water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. The preheating coil 232 is supplied with either hot water or steam to transfer heat energy to the outside air 10, raising its temperature. Furthermore, the at least one first temperature device 23 can also be any one or a combination of precooler 233 and preheater 234 (e.g., ...). Figure 1 As shown), the precooler 233 is any one of a shell-and-tube cooler, a finned tube cooler, or a plate heat exchanger cooler, and the preheater 234 is any one of an electric heater, a gas heater, a thermal oil heater, or a hot water heater.

[0061] The at least one water washing device 24 is a washing humidifier, mainly composed of at least one pressure pump, at least one nozzle, at least one water supply valve, at least one drain valve, and at least one pipeline (not shown). When the outside air 10 passes through the washing humidifier, water molecules will fully absorb heat from the air and vaporize, increasing the humidity of the outside air 10 to form humid air. The at least one second temperature device 26 is either or a combination of a recooling coil 261 and a reheating coil 262 (not shown) (e.g., Figure 2 As shown), the recooling coil 261 is supplied with either cooling water or chilled water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. The reheating coil 262 (not shown) is supplied with either hot water or steam to transfer heat to the outside air 10, raising its temperature. Furthermore, the at least one second temperature device 26 can also be any one or a combination of a recooler 263 and a reheater 264 (e.g., ...). Figure 1 As shown), the recooler 263 is any one of a shell-and-tube cooler, a finned tube cooler, or a plate heat exchanger cooler, and the reheater 264 is any one of an electric heater, a gas heater, a thermal oil heater, or a hot water heater.

[0062] The outside air 10, after being processed by at least one first filter device 22, at least one first temperature device 23, at least one water washing device 24, and at least one second temperature device 26, is sent into the processing zone 251 of the dehumidification rotor 25 for dehumidification and adsorption (e.g., Figure 1 and Figure 2 As shown in the figure, the dehumidifying impeller 25 is arranged in any one of the front, rear, or middle positions of the second temperature device 26. The figure of the present invention shows the dehumidifying impeller 25 located in the middle of the second temperature device 26, but is not limited to the figure. Three-quarters of the area of ​​the dehumidifying impeller 25 is the processing zone 251. When the outside air 10 to be processed passes through the processing zone 251, the moisture in the outside air 10 is absorbed by the desiccant attached to the special fibers, becoming low-humidity dry air, and is blown out from the other end of the processing zone 251. This allows the absolute humidity of the outside air 10 after passing through the at least one water washing device 24 to be adjusted to the required level through condensation dehumidification.

[0063] The first heat exchanger 30 provides a heat source to the regeneration zone 252 (e.g., Figure 1 and Figure 2As shown in the diagram, the heat source has a temperature exceeding 100°C and enters the remaining 1 / 4 area of ​​the dehumidifying rotor 25, which is the regeneration zone 252, in the opposite direction. The heat source slowly enters the regeneration zone 252 to raise the temperature of the desiccant attached to the special fibers, causing the moisture contained in the desiccant to vaporize and be carried out of the dehumidifying rotor 25. This allows the desiccant attached to the special fibers to regain its moisture-absorbing function, i.e., the desiccant is regenerated. Furthermore, while the dehumidifying rotor 25 rotates slowly, the moisture absorption and regeneration processes of the desiccant attached to the special fibers occur simultaneously, thus ensuring a continuous and stable output of dry air from the dehumidifying rotor 25.

[0064] Furthermore, at least one second filter device 27 is provided inside the housing 21 of the external air conditioning system 20, and the at least one second filter device 27 is located in the rear section of the housing 21 (e.g., Figure 1 and Figure 2 As shown), the outside air 10, after being dehumidified and adsorbed in the processing zone 251 of the dehumidifying rotor 25, enters the at least one second filter device 27 for filtration. The at least one second filter device 27 is any one or a combination of a high-efficiency particulate air filter (HEPA) or an ultra-low penetration rate air filter (ULPA). The high-efficiency particulate air filter (HEPA) is suitable for end-point filtration and has an efficiency of 99.998% for particles of 0.1 microns and 0.3 microns. The removal efficiency for particles with a diameter of 0.3 microns or larger (1 / 200th the diameter of a human hair) can reach more than 99.7%. It is the most effective filter medium for pollutants such as smoke, dust and bacteria, and the material is mainly ultra-fine glass fiber paper or composite filter paper. The Ultra Low Penetration Air Filter (ULPA) is mainly used to remove particles larger than 0.12µm (120 nanometers), with a filtration efficiency of approximately DOP 99.995% or higher, and the material is mainly made of special ultra-fine glass fiber paper.

[0065] Additionally, a fan 28 is installed inside the housing 21 of the external air conditioning system 20, and the fan 28 is located in front of the dehumidification impeller 25 (e.g., Figure 2 As shown), the dehumidifying rotor 25 (as shown) Figure 1Any one of the points shown (as shown) primarily provides power to push and pull the outside air 10 forward, allowing the outside air 10 to sequentially pass through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24, and the at least one second temperature device 26 for processing (dust removal, filtration, and temperature and humidity control via the aforementioned devices), or sequentially pass through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24, the at least one second temperature device 26, and the dehumidification wheel 25 for processing (dust removal, filtration, and temperature and humidity control via the aforementioned devices, and then transported to the processing area 251 of the dehumidification wheel 25 for dehumidification adsorption), thereby achieving the function of generating fresh air with constant temperature and humidity.

[0066] Furthermore, the outdoor air conditioning system 20 is connected to the duct 70 so that the air delivered by the outdoor air conditioning system 20 can be transported to the required location (such as...) through the duct 70. Figure 1 and Figure 2 As shown in the figure, the duct 70 is connected to any one of at least one cleanroom 71, at least one ward (not shown), at least one food processing area (not shown), at least one semiconductor process plant area (not shown), and at least one electronic process plant area (not shown), so as to provide the above-mentioned places with the need to replenish a large amount of outside air, and drive the airflow circulation in the above-mentioned places to remove dust and heat, achieve the required cleanliness and ventilation, and replace the original air.

[0067] Furthermore, the dehumidifying impeller 25 of the present invention is additionally provided with a bypass device 80 (such as...). Figure 2 As shown in the figure, the bypass device 80 is either a pipe or a shelf. The pipe is mainly connected to the front and rear ends of the processing area 251 of the dehumidifying impeller 25 by a bypass pipe provided on the outside of the housing 21 or a bypass pipe provided on the inside of the housing 21, and is equipped with a control valve for opening and closing. The shelf is mainly a bypass shelf provided inside the housing 21 (not shown). When needed, the bypass shelf will cover the processing area 251 of the dehumidifying impeller 25 to form a gas channel, so that the outside air 10 can bypass the dehumidifying impeller 25 after passing through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24 and the at least one second temperature device 26 in sequence. This bypass facility is designed to change the airflow direction in case the dehumidifying impeller 25 fails, the dehumidifying impeller 25 becomes saturated, or other force majeure factors occur, so as to prevent the outside air conditioning system 20 from failing to operate.

[0068] Therefore, the present invention mainly utilizes the combined design of an outside air 10, an outside air air conditioning system 20, a first heat exchanger 30, a water tank 40, a second heat exchanger 50, an incineration device 60, and an air duct 70 to enable the waste heat discharged from the incineration device 60 to be supplied to the dehumidification rotor 25 of the outside air air conditioning system 20 to remove the latent heat of the outside air 10, and then transported to the required location through the air duct 70. Thus, it has the efficiency of heat recovery application and energy saving and carbon reduction, and can also reduce energy consumption, thereby increasing the overall practicality.

[0069] The waste heat recovery-equipped outdoor air conditioning method of the present invention mainly utilizes a combination design of an outside air unit 10, an outside air conditioning system 20, a first heat exchanger 30, a water tank 40, a second heat exchanger 50, an incineration device 60, and a duct 70 (e.g., Figure 1 and Figure 2 As shown, the outdoor air conditioning system 20 is provided with a housing 21. The housing 21 is designed to house at least one first filter device 22, at least one first temperature device 23, at least one water washing device 24, a dehumidifying impeller 25, and at least one second temperature device 26. The dehumidifying impeller 25 has a processing area 251 and a regeneration area 252. The first heat exchanger 30 is connected to the regeneration area 252 of the dehumidifying impeller 25. The water tank 40 is connected to the first heat exchanger 30. The second heat exchanger 50 is connected to the water tank 40 and the first heat exchanger 30. The air duct 70 is connected to the outdoor air conditioning system 20.

[0070] The main steps of this waste heat recovery-equipped outdoor air conditioning method (such as...) Figure 3 As shown, step S100 involves the introduction of outside air: the outside air conditioning system 20 supplies outside air 10 into the system. After completing step S100, the next step S110 is performed.

[0071] The aforementioned outside air 10 contains at least one gas or combination thereof, mainly consisting of a mixture of 78.1% nitrogen, 21% oxygen, 0.9% argon, and other impurities. The outside air 10 is also commonly known as air.

[0072] Furthermore, the next step, S110, involves outside air treatment: the outside air 10 is treated by the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24, and the at least one second temperature device 26. After completing step S110, the next step, S120, is performed.

[0073] The aforementioned outdoor air conditioning system 20 includes a housing 21 with an outdoor air inlet 211 for the entry of outdoor air 10. The housing 21 of the outdoor air conditioning system 20 is internally designed with at least one first filter device 22, at least one first temperature device 23, at least one water washing device 24, a dehumidifying impeller 25, and at least one second temperature device 26 (e.g., ...). Figure 1 and Figure 2 (As shown).

[0074] In the next step, S120, dehumidification adsorption is performed: the outside air 10 enters the dehumidification rotor 25 and undergoes dehumidification adsorption through the processing zone 251 of the dehumidification rotor 25. After completing the above step S120, the next step S130 is performed.

[0075] The aforementioned dehumidifying rotor 25 is a special honeycomb-shaped paper rotor containing a desiccant. Because the honeycomb pore size is only 1.5mm, it can achieve a 1m... 3 The rotary paper core has a moisture absorption area of ​​3000m². 2 Airflow through the honeycomb-shaped channels is in a boundary laminar flow state, resulting in good moisture exchange and thus strong dehumidification capacity. Furthermore, the dehumidification rotor 25 has a processing zone 251 and a regeneration zone 252.

[0076] Furthermore, in the next step S130, combustion exhaust gas is discharged: the incineration equipment 60 discharges combustion exhaust gas 61, which has a temperature, and the combustion exhaust gas 61 passes through the second heat exchanger 50. After completing the above step S130, the next step S140 is performed.

[0077] The aforementioned incineration equipment 60 is any one of a direct-fired incinerator (TO), a catalytic incinerator (not shown), or a regenerative thermal oxidizer (RTO) (not shown). When the incineration equipment 60 is a direct-fired incinerator (TO), it is equipped with any one of two, three, or four heat exchangers 62. The incineration equipment 60 is combined with any one of a dual-rotor volatile organic compound (VOC) treatment system (not shown) or a single-rotor volatile organic compound (VOC) treatment system (not shown), and the incineration equipment 60 discharges a combustion exhaust gas 61 (such as...). Figure 1 and Figure 2 As shown), the combustion exhaust gas 61 has a temperature exceeding 150°C.

[0078] In the next step, S140, heat transfer occurs: the water tank 40 outputs water, and the water in the water tank 40 transfers heat from the second heat exchanger 50 to the first heat exchanger 30. After completing step S140, the next step, S150, is performed.

[0079] The first heat exchanger 30 is connected to the regeneration zone 252 and provides a heat source to the regeneration zone 252 for desorption. A gas is introduced into the first heat exchanger 30; this gas can be either outside air or gas treated in the processing zone (not shown) for heat exchange. The water tank 40 is connected to both the first heat exchanger 30 and the second heat exchanger 50 (e.g.,...). Figure 1 and Figure 2 As shown, the water tank 40 outputs water, which can be any one of filtered water, tap water, cooling water, or chilled water. The water in the water tank 40 transfers heat from the second heat exchanger 50 to the first heat exchanger 30. The water tank 40 is connected to a pump 42 to propel the water in, and the water tank 40 is equipped with a water valve 41 to control the water entering the water tank 40, thus enabling the water tank 40 to replenish its water supply. Both the first heat exchanger 30 and the second heat exchanger 50 are liquid-to-gas heat exchangers.

[0080] Furthermore, in the next step S150, a heat source is provided: the first heat exchanger 30 provides a heat source to the regeneration zone 252 for desorption. After completing the above step S150, the next step S160 is performed.

[0081] In steps S130, S140, and S150 above, the incineration equipment 60 discharges a combustion exhaust gas 61. This combustion exhaust gas 61 has a temperature exceeding 150°C, and it passes through the second heat exchanger 50 (e.g., Figure 1 and Figure 2 As shown, the water and gas in the second heat exchanger 50 exchange heat, allowing the water in the water tank 40 to transfer heat to the first heat exchanger 30 for use. The water and gas in the first heat exchanger 30 then exchange heat again, delivering the heat-generating gas to the regeneration zone 252 for thermal desorption. The desorbed gas is then discharged to the outside, which could be either the sky or the chimney 90. The combustion exhaust gas 61, after heat exchange in the second heat exchanger 50, is then delivered to the chimney 90 for emission.

[0082] In addition, the next step S160 is to deliver the gas to the duct: the gas delivered by the outdoor air conditioning system 20 is delivered to the duct 70.

[0083] The aforementioned outdoor air conditioning system 20 is connected to the duct 70 so that the air supplied by the outdoor air conditioning system 20 can be transported to the required location (such as...) through the duct 70. Figure 1 and Figure 2As shown), the duct 70 is connected to any one of the following: at least one cleanroom 71, at least one ward (not shown), at least one food processing area (not shown), at least one semiconductor process plant area (not shown), and at least one electronic process plant area (not shown).

[0084] The dehumidifying impeller 25 is further designed with at least one first filter device 22, at least one first temperature device 23, and at least one washing device 24. The at least one first filter device 22 is any one or a combination of a pre-filter or a medium efficiency filter. The pre-filter is mostly plate-shaped, suitable for primary filtration, mainly used to filter dust particles larger than 5μm, and its materials are mainly non-woven fabric, nylon mesh, activated carbon filter media, and metal mesh. The medium efficiency filter is mostly bag-shaped, widely used for intermediate filtration, mainly used to filter dust particles larger than 1-5μm, and its materials are mainly synthetic fibers and non-woven fabric. The at least one first temperature device 23 is any one or a combination of a pre-cooling coil 231 and a preheating coil 232 (e.g., Figure 2 As shown), the precooling coil 231 is supplied with either cooling water or ice water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. The preheating coil 232 is supplied with either hot water or steam to transfer heat energy to the outside air 10, raising its temperature. Furthermore, the at least one first temperature device 23 can also be any one or a combination of precooler 233 and preheater 234 (e.g., ...). Figure 1 As shown), the precooler 233 is any one of a shell-and-tube cooler, a finned tube cooler, or a plate heat exchanger cooler, and the preheater 234 is any one of an electric heater, a gas heater, a thermal oil heater, or a hot water heater.

[0085] The at least one water washing device 24 is a washing humidifier, mainly composed of at least one pressure pump, at least one nozzle, at least one water supply valve, at least one drain valve, and at least one pipeline (not shown). When the outside air 10 passes through the washing humidifier, water molecules will fully absorb heat from the air and vaporize, increasing the humidity of the outside air 10 to form humid air. The at least one second temperature device 26 is either or a combination of a recooling coil 261 and a reheating coil 262 (not shown) (e.g., Figure 2As shown), the recooling coil 261 is supplied with either cooling water or chilled water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. The reheating coil 262 (not shown) is supplied with either hot water or steam to transfer heat to the outside air 10, raising its temperature. Furthermore, the at least one second temperature device 26 can also be any one or a combination of a recooler 263 and a reheater 264 (e.g., ...). Figure 1 As shown), the recooler 263 is any one of a shell-and-tube cooler, a finned tube cooler, or a plate heat exchanger cooler, and the reheater 264 is any one of an electric heater, a gas heater, a thermal oil heater, or a hot water heater.

[0086] The outside air 10, after being processed by at least one first filter device 22, at least one first temperature device 23, at least one water washing device 24, and at least one second temperature device 26, is sent into the processing zone 251 of the dehumidification rotor 25 for dehumidification and adsorption (e.g., Figure 1 and Figure 2 As shown in the figure, the dehumidifying impeller 25 is arranged in any one of the front, rear, or middle positions of the second temperature device 26. The figure of the present invention shows the dehumidifying impeller 25 located in the middle of the second temperature device 26, but is not limited to the figure. Three-quarters of the area of ​​the dehumidifying impeller 25 is the processing zone 251. When the outside air 10 to be processed passes through the processing zone 251, the moisture in the outside air 10 is absorbed by the desiccant attached to the special fibers, becoming low-humidity dry air, and is blown out from the other end of the processing zone 251. This allows the absolute humidity of the outside air 10 after passing through the at least one water washing device 24 to be adjusted to the required level through condensation dehumidification.

[0087] The first heat exchanger 30 provides a heat source to the regeneration zone 252 (e.g., Figure 1 and Figure 2 As shown in the diagram, the heat source has a temperature exceeding 100°C and enters the remaining 1 / 4 area of ​​the dehumidifying rotor 25, which is the regeneration zone 252, in the opposite direction. The heat source slowly enters the regeneration zone 252 to raise the temperature of the desiccant attached to the special fibers, causing the moisture contained in the desiccant to vaporize and be carried out of the dehumidifying rotor 25. This allows the desiccant attached to the special fibers to regain its moisture-absorbing function, i.e., the desiccant is regenerated. Furthermore, while the dehumidifying rotor 25 rotates slowly, the moisture absorption and regeneration processes of the desiccant attached to the special fibers occur simultaneously, thus ensuring a continuous and stable output of dry air from the dehumidifying rotor 25.

[0088] Furthermore, at least one second filter device 27 is provided inside the housing 21 of the external air conditioning system 20, and the at least one second filter device 27 is located in the rear section of the housing 21 (e.g., Figure 1 and Figure 2 As shown), the outside air 10, after being dehumidified and adsorbed in the processing zone 251 of the dehumidifying rotor 25, enters the at least one second filter device 27 for filtration. The at least one second filter device 27 is any one or a combination of a high-efficiency particulate air filter (HEPA) or an ultra-low penetration rate air filter (ULPA). The high-efficiency particulate air filter (HEPA) is suitable for end-point filtration and has an efficiency of 99.998% for particles of 0.1 microns and 0.3 microns. The removal efficiency for particles with a diameter of 0.3 microns or larger (1 / 200th the diameter of a human hair) can reach more than 99.7%. It is the most effective filter medium for pollutants such as smoke, dust and bacteria, and the material is mainly ultra-fine glass fiber paper or composite filter paper. The Ultra Low Penetration Air Filter (ULPA) is mainly used to remove particles larger than 0.12µm (120 nanometers), with a filtration efficiency of approximately DOP 99.995% or higher, and the material is mainly made of special ultra-fine glass fiber paper.

[0089] Additionally, a fan 28 is installed inside the housing 21 of the external air conditioning system 20, and the fan 28 is located in front of the dehumidification impeller 25 (e.g., Figure 2 As shown), the dehumidifying rotor 25 (as shown) Figure 1 Any one of the points shown (as shown) primarily provides power to push and pull the outside air 10 forward, allowing the outside air 10 to sequentially pass through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24, and the at least one second temperature device 26 for processing (dust removal, filtration, and temperature and humidity control via the aforementioned devices), or sequentially pass through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24, the at least one second temperature device 26, and the dehumidification wheel 25 for processing (dust removal, filtration, and temperature and humidity control via the aforementioned devices, and then transported to the processing area 251 of the dehumidification wheel 25 for dehumidification adsorption), thereby achieving the function of generating fresh air with constant temperature and humidity.

[0090] Furthermore, the outdoor air conditioning system 20 is connected to the duct 70 so that the air delivered by the outdoor air conditioning system 20 can be transported to the required location (such as...) through the duct 70. Figure 1 and Figure 2 As shown in the figure, the duct 70 is connected to any one of at least one cleanroom 71, at least one ward (not shown), at least one food processing area (not shown), at least one semiconductor process plant area (not shown), and at least one electronic process plant area (not shown), so as to provide the above-mentioned places with the need to replenish a large amount of outside air, and drive the airflow circulation in the above-mentioned places to remove dust and heat, achieve the required cleanliness and ventilation, and replace the original air.

[0091] Furthermore, the dehumidifying impeller 25 of the present invention is additionally provided with a bypass device 80 (such as...). Figure 2 As shown in the figure, the bypass device 80 is either a pipe or a shelf. The pipe is mainly connected to the front and rear ends of the processing area 251 of the dehumidifying impeller 25 by a bypass pipe provided on the outside of the housing 21 or a bypass pipe provided on the inside of the housing 21, and is equipped with a control valve for opening and closing. The shelf is mainly a bypass shelf provided inside the housing 21 (not shown). When needed, the bypass shelf will cover the processing area 251 of the dehumidifying impeller 25 to form a gas channel, so that the outside air 10 can bypass the dehumidifying impeller 25 after passing through the at least one first filter device 22, the at least one first temperature device 23, the at least one water washing device 24 and the at least one second temperature device 26 in sequence. This bypass facility is designed to change the airflow direction in case the dehumidifying impeller 25 fails, the dehumidifying impeller 25 becomes saturated, or other force majeure factors occur, so as to prevent the outside air conditioning system 20 from failing to operate.

[0092] Therefore, the present invention mainly utilizes the combined design of an outside air 10, an outside air air conditioning system 20, a first heat exchanger 30, a water tank 40, a second heat exchanger 50, an incineration device 60, and an air duct 70 to enable the waste heat discharged from the incineration device 60 to be used by the dehumidification rotor 25 of the outside air air conditioning system 20 to remove the latent heat of the outside air 10, and then transport it to the required location through the air duct 70. Therefore, it has the efficiency of heat recovery application and energy saving and carbon reduction, and can also reduce energy consumption, thereby increasing the overall practicality.
