Description
Technical Field
[0001] This utility model relates to the field of dehumidification technology, and in particular to a high-efficiency, cost-reducing, and energy-saving dehumidification system. Background Technology
[0002] In industrial production and specific environmental control fields, maintaining precise humidity levels is crucial for ensuring product quality, process stability, and equipment safety. For example, in industries such as pharmaceuticals, precision electronics manufacturing, and food processing, excessively high humidity can lead to product deterioration due to moisture absorption, microbial growth, equipment corrosion, static electricity problems, or affect the precision of production processes. Dehumidifiers, as core equipment for regulating environmental humidity, typically operate based on technologies such as physical adsorption or condensation. By processing a certain amount of air, removing its moisture, and then delivering the dry air to the target area, they achieve the purpose of dehumidification.
[0003] Currently, for multiple workshops or areas with varying humidity requirements, there are two main conventional solutions: First, a separate dehumidification system is configured for each area with different humidity requirements, using multiple dehumidifiers for individual control. While this approach allows for independent and precise control of each area, it directly leads to an increase in the number of devices, a significant rise in the overall initial investment, and requires more space, resulting in higher daily operation, management, and maintenance costs. Second, a single, larger dehumidifier is used to handle the air demand of all areas, attempting to meet individual humidity requirements by adjusting the airflow allocated to different areas. However, this approach has significant drawbacks: it requires simultaneous airflow allocation to multiple areas, meaning the dehumidifier must handle the total airflow required by multiple areas at once. The larger the total volume of air handled, the greater the amount of moisture that needs to be adsorbed or removed, leading to a substantial increase in energy consumption and high operating costs. Furthermore, it places higher demands on the dehumidifier, resulting in a higher initial investment.
[0004] Therefore, there is an urgent need to design a cost-saving and energy-efficient dehumidification system that can effectively meet the humidity control needs of different areas while significantly reducing initial equipment investment and operating energy consumption. Summary of the Invention
[0005] The purpose of this invention is to provide a highly efficient, cost-saving, and energy-saving dehumidification system that solves the problems of high equipment cost and high operating energy consumption in existing dehumidification systems when meeting the humidity control needs of different areas.
[0006] To achieve this objective, the present invention adopts the following technical solution: A high-efficiency, cost-reducing, and energy-saving dehumidification system includes a dehumidifier, a circulation mechanism, an air supply duct, an intermediate duct, and a return air duct, applied to several target areas with different humidity requirements. The target areas with different humidity requirements are connected in series, and the required humidity values of the target areas increase sequentially along the air circulation direction. The air supply duct connects the dehumidifier outlet to the first target area. The circulation mechanism is located on the intermediate duct, which connects two adjacent target areas. The return air duct connects the last target area to the dehumidifier inlet.
[0007] Furthermore, the air supply duct and the intermediate duct are both equipped with switch valves.
[0008] Furthermore, it also includes a first transfer pipeline and a second transfer pipeline. Each target area other than the first target area is connected to the dehumidifier via a first transfer pipeline, and each target area other than the last target area is connected to the dehumidifier via a second transfer pipeline. Each of the first transfer pipeline and the second transfer pipeline is equipped with a switch valve.
[0009] Furthermore, a humidity sensor is installed in each target area.
[0010] Furthermore, it also includes a controller, which is signal-connected to the dehumidifier, circulation mechanism, switching valve, and humidity sensor.
[0011] Furthermore, the humidity requirements for different target areas include a first target area and a second target area, wherein the first target area is configured as the first target area and the last target area is configured as the second target area, and the humidity value required for the first target area is lower than the humidity value required for the second target area.
[0012] Furthermore, each target area includes at least one workshop.
[0013] Furthermore, check valves and filter grilles are installed on both the air supply duct and the intermediate duct.
[0014] Furthermore, the circulation mechanism includes a circulating air handling unit.
[0015] Compared with the prior art, the present invention has the following beneficial effects: The high-efficiency, cost-reducing, and energy-saving dehumidification system provided by this utility model uses a series airflow path to circulate dehumidified air from low-humidity requirement areas to high-humidity requirement areas, utilizing its remaining drying capacity for secondary moisture absorption, thereby maximizing dehumidification efficiency, reducing the total air volume handled by the dehumidifier, and achieving energy saving and consumption reduction; at the same time, it eliminates the need for multiple dehumidifiers, reducing the initial investment in equipment.
[0016] In this embodiment, the efficient, cost-reducing, and energy-saving dehumidification system continuously collects humidity information from each target area using humidity sensors. The controller analyzes the data and dynamically adjusts the dehumidifier's operating status, the circulation mechanism's operating status, and the status of the pipeline valves. For example, if dehumidification is temporarily unnecessary after the humidity of the first target area meets the standard, or for other reasons, the pipeline leading to that target area can be closed, and dry air can be directly introduced to the next target area, reducing unnecessary energy consumption. Similarly, if dehumidification is temporarily unnecessary after the humidity of the last target area meets the standard, or for other reasons, the pipeline from the previous target area to the last target area can be closed, and the previous target area can be directly connected to the dehumidifier, reducing the overall circulation length and the energy consumption of the circulation mechanism.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1: The high-efficiency, cost-reducing, and energy-saving dehumidification system described in this embodiment is applied to several target areas with different humidity requirements. Combined with... Figure 1As shown, the high-efficiency, cost-reducing, and energy-saving dehumidification system includes a dehumidifier 1, a circulation mechanism, an air supply duct 31, an intermediate duct 32, and a return air duct 33. Target areas with different humidity requirements are connected in series, with the required humidity values increasing sequentially along the air circulation direction. This configuration allows air to flow from areas with low humidity to areas with high humidity, thereby maximizing the utilization of the residual dehumidification capacity of dry air, reducing the demand for fresh dry air, and improving the overall system efficiency. The air supply duct 31 connects the outlet of the dehumidifier 1 to the first target area. The dehumidifier 1 processes the incoming air, removing moisture through adsorption or condensation mechanisms to output low-humidity dry air, providing a basis for precise humidity control in the first target area. The circulation mechanism is located on the intermediate duct 32, which connects two adjacent target areas. The circulation mechanism provides wind power to drive airflow, ensuring stable airflow transmission. The circulation mechanism includes a circulating air handling unit 2. In this embodiment, each intermediate duct 32 is equipped with a circulation mechanism to enhance the air transport capacity between different target areas, maintain the dynamic balance of airflow within the system, and prevent airflow stagnation or pressure loss. The return air duct 33 connects the final target area and the dehumidifier 1, returning the air that has been used by multiple target areas to the dehumidifier 1 for further processing, forming a closed-loop cycle and reducing external air input and energy waste. Each target area includes at least one workshop. This design allows the system to flexibly adapt to multiple workshop environments, achieve optimized resource allocation by centrally managing different humidity requirements, avoid setting up separate dehumidification equipment for each workshop, thereby simplifying the system structure and reducing costs.
[0025] The air supply duct 31 and intermediate duct 32 are each equipped with a switch valve, a check valve 61, and a filter grille 62. The switch valve is used to manually or automatically control the opening and closing of the airflow passage to achieve airflow regulation and area isolation; the check valve 61 is used to prevent airflow from flowing in reverse and ensure unidirectional flow; the filter grille 62 is used to filter particulate matter and impurities in the air, protect system components from contamination, extend equipment life, and improve air quality.
[0026] In this embodiment, the target areas with different humidity requirements include a first target area 51 and a second target area 52. The first target area is configured as the first target area 51, and the last target area is configured as the second target area 52. The humidity value required by the first target area 51 is lower than that required by the second target area 52. In a specific embodiment, the humidity requirement of the first target area 51 is 10%, and the humidity requirement of the second target area 52 is 20%. When the high-efficiency cost-reducing and energy-saving dehumidification system is working, the dehumidifier 1 outputs dry air and sends it to the first target area 51 with a humidity requirement of 10% through the air supply duct 31. After dehumidification is completed in this area, the humidity in the air is lower than the 20% humidity requirement. The return air is guided by the circulation mechanism and transported to the second target area 52 with a humidity requirement of 20% through the intermediate duct 32. It uses its residual drying capacity for secondary dehumidification. Then, the air returns to the dehumidifier 1 through the return air duct 33 for regeneration, forming a continuous cycle. This allows multiple humidity requirements to be covered with a single processing air volume, significantly reducing the system load. In a specific embodiment, for workshops of the same volume, one dehumidifier can simultaneously meet the humidity requirements of 10% and 20% by processing only a small amount of air once.
[0027] The high-efficiency, cost-reducing, and energy-saving dehumidification system of this invention utilizes a series airflow path to circulate dehumidified air from low-humidity requirement areas to high-humidity requirement areas, utilizing its remaining drying capacity for secondary moisture absorption, thereby maximizing dehumidification efficiency and reducing the total air volume handled by dehumidifier 1, achieving energy saving and consumption reduction. Simultaneously, it eliminates the need for multiple dehumidifiers 1, reducing initial equipment investment. In a specific embodiment, when simultaneously meeting the 10% and 20% humidity requirements of different workshops, in terms of initial investment, the high-efficiency, cost-reducing, and energy-saving dehumidification system of this invention saves 240,000 yuan (29%) compared to a general dehumidification system; in terms of energy consumption, the high-efficiency, cost-reducing, and energy-saving dehumidification system of this invention saves 635,000 yuan annually (18%) compared to a general dehumidification system.
[0028] Example 2: Combination Figure 2As shown, the difference between this embodiment and Embodiment 1 is that the high-efficiency dehumidification system described in this embodiment further includes a first transfer pipe 41, a second transfer pipe 42, a humidity sensor, and a controller. Each target area other than the first target area is provided with a first transfer pipe 41 between itself and the dehumidifier 1, and each target area other than the last target area is provided with a second transfer pipe 42 between itself and the dehumidifier 1. The first transfer pipe 41 is used to directly introduce dry air from the dehumidifier 1 to a specific target area when needed, thereby enhancing the local humidity regulation capability. For example, it can directly introduce dry air from the dehumidifier 1 to the next target area after the first target area. The second transfer pipe 42 is used to quickly return the air from the specific target area to the dehumidifier 1, optimizing the return path. For example, it can directly and quickly return the air from the previous target area of the last target area to the dehumidifier 1. Both the first transfer pipeline 41 and the second transfer pipeline 42 are equipped with on / off valves, allowing the controller to flexibly adjust the airflow path to adapt to dynamic humidity changes. In this embodiment, the on / off valves can automatically control the opening and closing of their respective pipelines according to controller commands. A humidity sensor is installed in each target area to monitor the humidity level in real time and provide feedback signals to support intelligent control. The controller, dehumidifier 1, circulation mechanism, on / off valves, and humidity sensors are all signal-connected. Based on sensor data, the controller automatically adjusts the operating parameters of dehumidifier 1, the power of the circulation mechanism, and the opening and closing of the on / off valves to achieve adaptive humidity management. The key point of this embodiment is the introduction of a first transfer pipeline 41 and a second transfer pipeline 42. The first transfer pipeline 41 can be opened or closed by a switch valve on the first transfer pipeline 41 when needed to achieve the on / off state of the first transfer pipeline 41. The second transfer pipeline 42 can be opened or closed by a switch valve on the second transfer pipeline 42 when needed to achieve the on / off state of the second transfer pipeline 42. As for other structures such as humidity sensors, controllers, and switch valves, their control principles and structures are known to those skilled in the art and will not be specifically elaborated in this embodiment.
[0029] In this embodiment, the efficient, cost-reducing, and energy-saving dehumidification system continuously collects humidity information from each target area using humidity sensors. After analyzing the data, the controller dynamically adjusts the operating status of the dehumidifier 1, the operating status of the circulation mechanism, and the status of the pipeline valves. For example, when the humidity of the first target area meets the standard and dehumidification is temporarily unnecessary, or when dehumidification is not required for other reasons, the pipeline leading to that target area can be closed, and dry air can be directly introduced into the next target area, reducing unnecessary energy consumption. When the humidity of the last target area meets the standard and dehumidification is temporarily unnecessary, or when dehumidification is not required for other reasons, the pipeline from the previous target area to the last target area can be closed, and the previous target area can be directly connected to the dehumidifier 1, reducing the overall circulation length and the energy consumption of the circulation mechanism.
[0030] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
