Description

Technical Field

[0001] The utility model relates to the technical field of workshop air-conditioning systems, and in particular to a dual air-conditioning system capable of zone control. Background Art

[0002] Due to the special requirements of clean workshops for production environment temperature, humidity, pressure, cleanliness, etc., the central air-conditioning system used in clean workshops often adopts purification air-conditioning to perform temperature, humidity and cleanliness treatment on the air sent into the workshop to eliminate various heat and humidity disturbances indoors and outdoors and reduce airborne particle pollution. However, conventional integrated designs in the existing technology often ignore the impact of production line differences on actual management and control. Due to the large area of ​​the workshop, when the load changes of local production lines are inconsistent, a single air-conditioning system cannot achieve precise adjustment of each local area. At the same time, since the air ducts of the overall air distribution system of the workshop are connected, and there are differences in the nature of the production lines, if the concentration of local dust components is quite different, there is a hidden danger of mutual contamination between different areas, resulting in a shortened service life of the workshop's high-efficiency filtration unit. In severe cases, the cleanliness of a large area of ​​the workshop exceeds the management and control requirements. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0024] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, "including" is not limited to the listed structures, but may optionally include structures not listed, or may optionally include other components inherent to those structures.

[0025] The present application discloses a dual air conditioning system with zoned control, which is mainly used in clean rooms with localized high-heat and dust-generating areas. Detailed descriptions are provided below.

[0026] Figure 1 A dual air conditioning system with partition control provided according to an embodiment of the present application is shown. Figure 1As shown, the dual air-conditioning system with zone control mainly includes: an anti-static partition 2, a first central air-conditioning system 3, and a second central air-conditioning system 4. Among them, the anti-static partition 2 is set in the clean workshop 1, dividing the entire space of the clean workshop 1 into a relatively clean area 5 and at least one high-heat and dust-generating area 6. The low-dust production line 7 of the clean workshop 1 is set in the relatively clean area 5, and the high-heat and high-dust production line 8 of the clean workshop 1 is set in the high-heat and dust-generating area 6. Each high-heat and dust-generating area 6 is equipped with a first central air-conditioning system 3, and the relatively clean area 5 is equipped with a second central air-conditioning system 4. Through the independent dual air-conditioning systems of the first central air-conditioning system 3 and the second central air-conditioning system 4, the high-heat and dust-generating area 6 and the relatively clean area 5 are respectively controlled and controlled in a zoned manner, which can achieve good temperature and humidity control effects in the high-heat and dust-generating area 6 and the relatively clean area 5, blocking the dust source to a certain extent, thereby avoiding the risk of cross-contamination, and ensuring that the overall environment of the clean workshop meets the requirements.

[0027] In one embodiment, if Figure 1 As shown, the high-heat and high-dust production line 8 in the clean workshop 1 is enclosed by the anti-static partition 2 to form a high-heat and dust-generating area 6, and the area of ​​the clean workshop 1 except the high-heat and dust-generating area 6 is a relatively clean area 5. Furthermore, during the installation of the anti-static partition 2, the two ends of the anti-static partition 2 perpendicular to the ground are respectively connected to the ceiling and the ground of the clean workshop 1, and the joints between the anti-static partition 2 and the ceiling and the ground are sealed with glue to ensure the sealing of the high-heat and dust-generating area 6. In addition, in the specific implementation process, the anti-static partition 2 can be selected according to the actual requirements of the clean workshop 1. The partition board of the corresponding material, for example, anti-static polyvinyl chloride (PVC) board.

[0028] In the embodiments of this application, Figure 1 As shown, the first central air-conditioning system 3 is an independent central air-conditioning system for the high-heat dust-generating area 6. Each set of the first central air-conditioning system 3 includes a high-dust air handling unit (Air Handle Unit, AHU) 31, a high-dust air supply port 32 and a high-dust exhaust system 33. The high-dust air handling unit AHU31 is located in an independent machine room outside the clean workshop 1, and is used to absorb outdoor fresh air and complete air treatment. The treated air is transported to the high-heat dust-generating area 6 through the high-dust air supply port 32, and the exhaust gas generated in the high-heat dust-generating area 6 is discharged to the outside of the clean workshop 1 through the independent high-dust exhaust system 33. Specifically, combined with Figure 1 and Figure 2As shown, the high dust air handling unit AHU31 is arranged outside the clean room 1, and the high dust air handling unit AHU31 includes a high dust fresh air section 311, a high dust primary filter unit 312, a high dust medium efficiency filter unit 313, a high dust surface cooling section 314, a high dust blower 315, and a high dust air supply section 316 which are connected in sequence. The high dust air supply port 32 is arranged on the ceiling of the high heat dust generating area 6, and the high dust air supply section 316 and the high dust air supply port 32 are connected through a high dust fan. The high-dust fresh air section 311 absorbs fresh air from outside. After that, the fresh air passes through the high-dust primary filter unit 312 and the high-dust medium-efficiency filter unit 313 for two-stage filtration and purification, and then passes through the high-dust surface cooling section 314 for cooling. Driven by the high-dust blower 315, the cooled air is transported to the high-dust air supply port 32 through the high-dust air supply section 316 and the high-dust air duct, and then sent into the high-heat dust generating area 6 through the high-dust air supply port 32. The high-dust exhaust system 33 is connected to the high-heat and high-dust production line 8 in the high-heat dust generating area 6 through the high-dust terminal exhaust branch pipe 34, and the exhaust gas generated in the high-heat dust generating area 6 is discharged outside the clean room 1.

[0029] Further, such as Figure 1 As shown, each high-temperature dust-generating area 6 is provided with a personnel inspection door 9 on the anti-static partition 2 to facilitate entry into the high-temperature dust-generating area 6 during production line inspection and personnel maintenance. In addition, each high-temperature dust-generating area 6 is also provided with a material transfer channel 10 on the anti-static partition 2 to facilitate the transportation of necessary materials and molds between the high-temperature dust-generating area 6 and the relatively clean area 5. At the same time, an automatic induction blowing device is provided in the material transfer channel 10. When the material or mold is transported from the high-temperature dust-generating area 6 to the relatively clean area 5, it can be purified by the automatic induction blowing device installed in the material transfer channel 10, thereby further avoiding the risk of cross-contamination between the two areas and ensuring that the overall environment of the clean workshop meets the requirements. It should be noted that the automatic induction blowing device in the embodiment of the present application can use a blowing device with an automatic induction function in the prior art, and its specific model and size can be selected according to the specific requirements of the clean workshop 1.

[0030] In the embodiments of this application, Figure 1As shown, the second central air conditioning system 4 is the central air conditioning system for the relatively clean area 5, and includes a low-dust air handling unit (AHU) 41, a low-dust air supply outlet 42, and a low-dust exhaust system 43. The low-dust air handling unit (AHU) 41 is located outside the cleanroom 1 and in an independent machine room outside the cleanroom 1. It absorbs fresh air from outside and processes the fresh air and return air, forming a mixed air flow of fresh air and return air. The low-dust air supply outlet 42 is located on the ceiling of the relatively clean area 5, and the return air section 414 of the low-dust air handling unit (AHU) 41 is connected to the interior of the relatively clean area 5, transporting air from the relatively clean area 5 to the low-dust air handling unit (AHU) 41 as indoor return air for the low-dust air handling unit (AHU) 41. The low-dust air supply outlet 42 is connected to the low-dust air supply section 420 of the low-dust air handling unit (AHU) 41 via a low-dust air duct, and the mixed air is transported into the relatively clean area 5 through the low-dust air supply outlet 42. The low-dust exhaust system 43 is independent of the high-dust exhaust system 33 and is connected to the low-dust production line 7 in the relatively clean area 5 via a low-dust terminal exhaust branch 44. This exhaust is then discharged outside the cleanroom 1 through the low-dust terminal exhaust branch 44. The second central air conditioning system 4 processes the exhaust from the relatively clean area 5 through the low-dust exhaust system 43. By treating the mixed air formed by fresh air and return air, it achieves replacement ventilation and temperature and humidity control for the entire cleanroom 1.

[0031] In one embodiment, if Figure 3As shown, the low-dust air handling unit AHU41 includes a low-dust fresh air section 411, a low-dust primary filter unit 412, a pre-cooling section 413, a return air section 414, a low-dust surface cooling section 415, a reheat section 416, a humidification section 417, a low-dust blower 418, a low-dust medium-efficiency filter unit 419, a low-dust air supply section 420 and a high-efficiency filter unit 45, which are connected in sequence. The high-efficiency filter unit 45 is arranged at the low-dust air supply port 42, and the low-dust air supply section 420 is connected to the low-dust air supply port 42 through the high-efficiency filter unit 45. The low-dust air handling unit AHU41 absorbs outdoor fresh air through the low-dust fresh air section 411. The fresh air is pre-treated by the low-dust primary filter unit 412 and the pre-cooling section 413, and then mixed with the indoor return air from the return air section 414. The mixed air is adjusted and coordinated by the low-dust surface cooling section 415, the reheating section 416, and the humidification section 417 in turn, and is powered by the low-dust blower 418. It passes through the low-dust medium-efficiency filter unit 419, the low-dust air supply section 420 and the low-dust air duct and is then transported to the high-efficiency filter unit 45. The high-efficiency filter unit 45 is located on the ceiling of the relatively clean area 5, so that the air entering the relatively clean area 5 is purified three times by the low-dust primary filter unit 412, the low-dust medium-efficiency filter unit 419, and the high-efficiency filter unit 45. After completing all three purifications, the air is sent into the relatively clean area 5 through the high-dust air supply port 32. During the specific implementation process, the operating mechanism of the low-dust air handling unit AHU41 itself can be adjusted according to the actual load demand of the relatively clean area 5 so that its processing effect can meet the control requirements of the dust-free workshop environment.

[0032] In some specific embodiments, the air supply volume of the high-dust air handling unit (AHU) 31 is no greater than the total exhaust volume of the high-dust exhaust system 33, thereby maintaining a slightly negative pressure environment in the high-heat dust-generating zone 6. Furthermore, the air supply volume of the low-dust air handling unit (AHU) of the second central air conditioning system 4 is the sum of the fresh air volume and the return air volume, and the air supply volume of the low-dust air handling unit (AHU) is no less than the total exhaust volume of the low-dust exhaust system 43 of the second central air conditioning system 4, thereby maintaining a positive pressure environment in the relatively clean zone 5. Thus, by maintaining a slightly negative pressure environment in the high-heat dust-generating zone 6 and a positive pressure environment in the relatively clean zone 5, the spread of contaminated air in the high-heat dust-generating zone 6 into the relatively clean zone 5 can be effectively reduced.

[0033] The above is an introduction to the various parts of the dual air conditioning system with zoned control provided by this embodiment and the connection relationship between them. Figure 1 – Figure 3 Taking a 100,000-class clean workshop as an example, the working principle of the dual air-conditioning system with partition control is described in detail.

[0034] When a high-heat, high-dust production line 8 is located in a Class 100,000 cleanroom 1, antistatic partitions 2 are used to create a high-heat, dust-generating zone 6 and a relatively clean zone 5. Dual air conditioning systems are deployed in both zones for zoning control. Based on the nature of the production line and the design of the flow of air, the first central air conditioning system 3 corresponding to the high-heat, dust-generating zone 6 includes three components: fresh air A1, supply air A2, and exhaust air A3. The second central air conditioning system 4 corresponding to the relatively clean zone 5 includes four components: fresh air B1, return air B4, supply air B2, and exhaust air B3.

[0035] The exhaust system of this cleanroom 1 is designed according to production line zoning. The high-heat and high-dust production line 8 uses an independent high-dust exhaust system 33 to treat the exhaust gas produced by the high-heat and dust-generating zone 6. A high exhaust velocity is designed based on the exhaust gas composition and regulatory requirements to efficiently discharge the exhaust gas and reduce the concentration of pollutants in the area. The high-dust air handling unit AHU31 adopts a structure in which a high-dust fresh air section 311, a high-dust primary filter unit 312, a high-dust medium-efficiency filter unit 313, a high-dust surface cooling section 314, a high-dust blower 315, and a high-dust air supply section 316 are connected in sequence. On the one hand, the return air from the high-heat and dust-generating zone 6 does not participate in the air circulation process of the high-dust air handling unit AHU31, which can avoid damage to the high-dust air handling unit AHU31 due to the high pollution risk in the high-heat and dust-generating zone, thereby extending the service life of the high-dust air handling unit AHU31. On the other hand, the dust-free air handling unit AHU31 is equipped with a two-stage filtration unit to process outdoor air, which is more cost-effective. The dust-free air handling unit AHU31 uses a fresh air system to inhale outdoor fresh air Q X1 When the influence of system leakage is ignored, the air supply volume Q can be approximately considered to be S1 =Q X1 , and design the air supply volume Q of the high dust air handling unit AHU31 S1 Not more than the total exhaust volume Q of the high dust exhaust system 33 P1 , detailed, Q S1 ≤(0.95~1)Q P1 This ensures that the high-heat dust-generating area 6 maintains a slightly negative pressure environment, effectively reducing the spread of contaminated air from the high-heat dust-generating area 6 to the relatively clean area 5. Furthermore, the low-temperature air treated by the high-dust air handling unit AHU31 is delivered to the high-heat dust-generating area 6, absorbing excess heat from the room and preventing localized overheating in the high-heat dust-generating area 6 from affecting the temperature and humidity control effectiveness of the relatively clean area 5.

[0036] The anti-static partition 2 is equipped with a personnel access door 9 and a material transfer channel 10. The personnel access door 9 is used for production line inspection and maintenance and remains closed during production line operation. The material transfer channel 10 is designed to facilitate the transportation of necessary materials and molds between the high-heat dust-generating area 6 and the relatively clean area 5. When materials or molds are transported from the high-heat dust-generating area 6 to the relatively clean area 5, they are purified by an automatic induction air shower installed in the material transfer channel 10.

[0037] The low-dust production line 7 uses another independent second central air-conditioning system 4 to treat the waste gas produced in the relatively clean area 5. Since the production line in the relatively clean area 5 has low pollution, according to the clean room design requirements, the relatively clean area 5 is controlled and treated by mixing conventional outdoor fresh air with indoor return air. The low-dust air handling unit AHU41 uses a primary return air system, and the fresh air volume Q X2 Supplement indoor exhaust and relatively clean area 5 positive pressure air volume to meet the air supply volume Q S2 The fresh air volume Q X2 and return air volume Q H2 The sum of X2 +Q H2 =Q S2 , air supply volume Q S2 The air change frequency required by the cleanliness level must be met, and the air supply volume Q of the low dust air handling unit AHU41 S2 Not less than the total exhaust volume Q of the low dust exhaust system 43 P2 , ensuring a positive pressure environment in the relatively clean area 5. Furthermore, the low-dust air handling unit AHU 41 is equipped with two filter units (i.e., a low-dust primary filter unit 412 and a low-dust medium-efficiency filter unit 419), and the third filter unit (i.e., a high-efficiency filter unit 45) is installed on the ceiling of the relatively clean area 5, further reducing the size of the low-dust air handling unit AHU 41.

[0038] In summary, the present application discloses a dual air-conditioning system that can be controlled by partitions. By deploying relatively independently operated dual air-conditioning systems, the systems can be adjusted to the optimal working state according to the load changes in each area, thereby achieving effective environmental regulation and clean management of high-heat dust-generating areas and other areas. The dual air-conditioning system is suitable for clean workshops with local high-heat dust-generating areas. The high-heat dust-generating areas use an independent set of central air-conditioning systems, which can reduce the heat diffusion effect of the high-heat dust-generating areas on other areas, and the corresponding coordinated design of the supply and exhaust air volumes can ensure a micro-negative pressure environment in the high-heat dust-generating areas, avoiding leakage of dust sources. At the same time, the central air-conditioning system used in the relatively clean area can meet the constant temperature, constant humidity, and positive pressure requirements of other areas of the workshop, ensuring that the environment except for the local high-heat dust-generating areas always meets the clean management standards.
