[0032] This utility model provides a dedicated air conditioning device for material storage spaces, improving upon common storage-type air conditioning systems currently on the market. It should be noted that existing storage-type air conditioning systems, such as... Figure 1 As shown, the system includes a housing 1, which has a return air duct 2 and a supply air duct 3. Inside the housing 1, a filter unit 11, a heat exchange unit 12, and a supply air unit 13 are sequentially arranged along the airflow path from the return air duct 2 to the supply air duct 3, forming the main processing air duct. The input end of the return air duct is connected to the material storage space, and the output end leads to the filter unit 11; the input end of the supply air duct 3 is connected to the supply air unit 13, and the output end leads to the storage space. The housing 1 also includes a control unit 14, and the heat exchange unit 12 and the supply air unit 13 are electrically connected to the control unit 14. The following will describe various improvements to the existing storage-type air conditioning system equipment described above, using multiple embodiments.

[0033] Example 1:

[0034] like Figure 2 As shown, the dedicated air conditioner for material storage space in this embodiment has been improved based on the existing storage-type air conditioning system equipment described above, as follows:

[0035] A bypass ventilation duct 4 is added inside the housing 1, and the bypass ventilation duct 4 is arranged side by side with the heat exchange unit 12. One end of the bypass ventilation duct 4 faces the filter unit 11 and is connected to the storage space through the filter unit 11 and the return air channel 2. The airflow inside the storage space enters the bypass ventilation duct 4 after passing through the return air channel 2 and the filter unit 11. The other end of the bypass ventilation duct 4 faces the air supply unit 13 and is connected to the input end of the air supply unit 13. At the same time, a humidification unit 41 (such as a wet film humidifier) ​​and a first air valve 42 (electric air valve) are arranged in the bypass ventilation duct 4 along the airflow direction. The front and rear positions of the two can be interchanged. Both are electrically connected to the control unit 14. The first air valve 42 is used to drive the airflow inside the material storage space into the bypass ventilation duct 4, and then flow through the humidification unit 41 in the bypass ventilation duct 4 for humidification. Finally, the airflow flows to the air supply unit 13 and is output back to the storage space.

[0036] In this embodiment, the return air duct 2 is also equipped with a return air temperature sensor and a humidity sensor, and the air supply unit 13 is also equipped with an air supply temperature sensor and a humidity sensor. Each temperature and humidity sensor is electrically connected to the control unit 14 to detect the temperature and humidity of the airflow flowing into and out of the housing 1. The humidity sensor is a dew point sensor, which detects the dew point temperature of the air to sense the water vapor content in the air in real time and feeds the data back to the control unit 14. The return air temperature sensor and the air supply temperature sensor monitor the temperature data of the return air duct 2 and the air supply unit 13 in real time and feed the data back to the control unit 14. The control unit 14 compares the feedback data with the set parameters and dynamically adjusts the operating power of the cooling, heating, humidifying, or dehumidifying modules to form a closed-loop control, ensuring uniform and stable temperature and humidity throughout the storage space. It can also flexibly adjust energy consumption according to actual needs, achieving energy saving and cost reduction while maintaining environmental indicators.

[0037] In this embodiment, when the dedicated air conditioner for the material storage space is working, the control unit 14 receives the return air temperature (temperature inside the storage space) and the supply air temperature (temperature after equipment processing) detected by the temperature sensor in real time. When the storage space needs temperature adjustment, the control unit 14 adjusts the cooling / heating output through the heat exchange unit 12 (such as an evaporator or chilled water coil), and simultaneously adjusts the opening of the bypass ventilation duct 4 through the first air valve 42. If the temperature difference between the supply air and the return air is too large, the first air valve 42 is opened, allowing the return air in the storage space to mix with the air processed by the heat exchange unit 12 through the bypass ventilation duct 4 (the humidity of which can be adjusted by the humidification unit 41) before the supply air unit 13, thus reducing the temperature difference between the supply air and the indoor air. When the storage space needs humidity adjustment: the control unit 14 adjusts the opening of the first air valve 42, controls the humidification unit 41 to humidify the airflow in the bypass ventilation duct 4 separately, and then sends it into the space through the supply air unit 13, achieving separate control of temperature and humidity.

[0038] The beneficial effects of this embodiment are as follows: the bypass ventilation duct 4 is built into the housing 1, which is compact and does not require additional external space of the housing 1, making it suitable for scenarios with limited installation space; by mixing the airflow of the bypass ventilation duct 4 and the humidification unit 41 with the airflow of the main treatment duct, the temperature and humidity parameter difference between the supply air and the indoor air is reduced, and the temperature and humidity gradient of the space is reduced; the temperature and humidity are controlled separately to avoid the cooling and heating cancellation of traditional equipment and reduce energy consumption; the control unit 14 is linked with each component to achieve intelligent adjustment and improve environmental stability.

[0039] Example 2:

[0040] like Figure 3 As shown, the dedicated air conditioner for material storage space in this embodiment is also an improvement on the existing storage air conditioning system equipment described above. The core logic of this embodiment is the same as that of Embodiment 1, except that the airflow source of the bypass ventilation duct 4 is as follows: In this embodiment, the bypass ventilation duct 4 is located on the outside of the housing 1, and the return air in the storage space is directly introduced through the bypass ventilation duct 4 outside the housing 1 without passing through the filter unit 11 inside the housing 1. The specific improvement scheme is as follows:

[0041] The bypass ventilation duct 4 is an independent duct structure separate from the housing 1, and is fixedly installed on the outside of the housing 1 by a bracket. One end of the bypass ventilation duct 4 is connected to the material storage space via a duct interface, and the other end passes through the side wall of the housing 1 via a sealing flange, connecting to the duct before the air supply unit 13. The humidification unit 41 and the first air valve 42 are fixed inside the bypass ventilation duct 4 by flanges, maintaining airflow communication with the air supply unit 13 inside the housing 1. The control unit 14 adjusts the return air volume of the bypass ventilation duct 4 through the first air valve 42, and in conjunction with the heat exchange unit 12 and the humidification unit 41, achieves precise matching of the supply air temperature and humidity with the indoor air.

[0042] In this embodiment, temperature and humidity sensors are installed at the air inlet ends of the return air duct 2, the air supply unit 13, and the bypass air duct 4. The working principle and control logic of the humidity and temperature sensors in this embodiment and the following embodiments are the same as those in Embodiment 1, and therefore will not be described again.

[0043] In addition, an internal filtration unit is installed inside the bypass ventilation duct 4. This unit can efficiently purify the airflow entering the bypass ventilation duct 4, intercepting dust, particulate impurities, and microorganisms from the air to prevent them from entering the storage space and contaminating the materials. At the same time, the filtration unit 11 works in conjunction with the temperature and humidity control functions of the air conditioning system to further optimize air quality while ensuring air cleanliness, providing a better environmental condition for material storage.

[0044] The beneficial effects of this embodiment are as follows: by placing the bypass ventilation duct 4 externally, it is convenient to modify existing storage air conditioning system equipment, and it is also convenient for later maintenance (such as replacement of humidification unit 41 and maintenance of air valve) without disassembling the cabinet 1; it is suitable for scenarios with high requirements for the utilization of the internal space of the cabinet 1, and the internal structure of the cabinet 1 does not need to be changed during the modification, resulting in lower costs; it retains the core advantages of separate temperature and humidity control and reduced gradient, and the external air duct can flexibly adjust its length and direction to adapt to different storage space layouts.

[0045] Example 3:

[0046] like Figure 4 As shown, this embodiment is an improvement on the dedicated air conditioner for material storage space in Embodiment 1. The core logic of this embodiment is the same as that of Embodiment 1, except that a fresh air duct 5 is added. The specific improvement scheme is as follows:

[0047] In this embodiment, the housing 1 is also provided with a fresh air duct 5, one end of which is connected to the outside of the material storage space, and the other end is connected to the filter unit 11. Specifically, the fresh air duct 5 and the return air duct 2 are arranged in parallel, and the air outlet of the return air duct 2 and the air outlet of the fresh air duct 5 both face the filter unit 11. A second air valve 51 is provided in the fresh air duct 5, and the second air valve 51 is electrically connected to the control unit 14. The second air valve 51 drives the airflow outside the material storage space to flow to the filter unit 11. The control unit 14 adjusts the fresh air volume through the second air valve 51 according to the temperature and humidity requirements in the storage space. When the outdoor fresh air temperature and humidity are suitable, the opening of the second air valve 51 is increased to introduce fresh air to replace part of the return air, which can reduce the humidity accumulation in the space, reduce the energy consumption of humidification / dehumidification, and reduce the load on the heat exchange unit 12. The fresh air and return air are mixed in front of the filter unit 11 and can be purified together by the filter unit 11 to prevent outdoor pollutants from entering the storage space. This is suitable for scenarios with high air quality requirements (such as precision material storage).

[0048] In addition, the fresh air duct 5 is equipped with a temperature and humidity sensor to monitor the temperature and humidity data of the fresh air in real time. The temperature and humidity sensor is electrically connected to the control unit 14, transmitting the signal to the air conditioning control unit 14. The control unit 14 intelligently adjusts the mixing ratio of fresh air and return air according to preset parameters and the actual needs of the storage space: when the humidity of the fresh air is too high, the proportion of return air is increased first to reduce the humidity of the mixed gas; if the temperature of the fresh air is suitable, the amount of fresh air introduced can be increased to assist in cooling the space, achieving precise temperature and humidity control and avoiding the impact of fluctuations in fresh air parameters on the storage environment. This design is particularly suitable for precision material storage scenarios that are sensitive to temperature and humidity, effectively improving the accuracy of environmental control.

[0049] Example 4:

[0050] like Figure 5As shown, this embodiment is also an improvement on the dedicated air conditioner for material storage space in Embodiment 1. The core logic of this embodiment is the same as that of Embodiment 1, except that a fresh air duct 5 is added. However, the location and arrangement of the fresh air duct 5 in this embodiment differ from those in Embodiment 3. The specific improvement scheme is as follows: the air inlet end of the fresh air duct 5 is connected to the outside of the storage space, and the air outlet end passes through the side wall of the return air duct 2. It is connected to the filter unit 11 through the return air duct 2, that is, the fresh air first enters the return air duct 2, and then flows to the filter unit 11 together with the return air. Similarly, the fresh air duct 5 is also equipped with a second air valve 51 and a temperature and humidity sensor, both of which are electrically connected to the control unit 14. In addition, an internal filter unit can be added to the fresh air duct 5. Its design principle and function are the same as the internal filter unit of the bypass ventilation duct 4 in Embodiment 2, and will not be described again here.

[0051] Compared to Embodiment 3, the fresh air and return air are pre-mixed in the return air duct 2, with the mixing point closer to the return air source, resulting in more thorough mixing, more uniform airflow, and higher airflow stability. This reduces local load fluctuations in the filter unit 11, avoids a decrease in filtration efficiency due to uneven local wind speeds, and improves the heat exchange efficiency of the heat exchange unit 12. At the same time, the structural design of the fresh air duct 5 penetrating into the return air duct 2 reduces the need for external ductwork in the housing 1, saving installation space.

[0052] Example 5:

[0053] like Figure 6 As shown, this embodiment is an improvement on the dedicated air conditioner for material storage space in Embodiment 2. The core logic of this embodiment is the same as that of Embodiment 2, the difference being the addition of a fresh air duct 5. The arrangement of the fresh air duct 5 is the same as in Embodiment 3, that is, the fresh air duct 5 and the return air duct 2 are connected in parallel, and the air outlets of the return air duct 2 and the fresh air duct 5 both face the filter unit 11. The core logic, working principle, and beneficial effects of the fresh air duct 5 in this embodiment are the same as those in Embodiment 3, and will not be repeated here.

[0054] Example 6:

[0055] like Figure 7 As shown, this embodiment is an improvement on the dedicated air conditioner for material storage space in Embodiment 2. The core logic of this embodiment is the same as that of Embodiment 2, the difference being the addition of a fresh air duct 5. The arrangement of the fresh air duct 5 is the same as in Embodiment 4, that is, one end of the fresh air duct 5 connects to the outside of the storage space, and the other end passes through the side wall of the return air duct 2, connecting to the filter unit 11 via the return air duct 2. Fresh air first enters the return air duct 2, and then flows together with the return air to the filter unit 11. The core logic, working principle, and beneficial effects of the fresh air duct 5 in this embodiment are the same as those in Embodiment 4, and will not be repeated here.

[0056] Example 7:

[0057] like Figure 8 As shown, this embodiment is an improvement on the dedicated air conditioner for material storage space in Embodiment 3. The core logic of this embodiment is the same as that of Embodiment 3, the difference being the addition of a reversing channel. The specific improvement scheme is as follows:

[0058] A reversing duct 6 is also provided between the return air duct 2 and the supply air duct 3, with both ends of the reversing duct 6 connected to the return air duct 2 and the supply air duct 3, respectively. A third air valve 61 is provided in the reversing duct 6, and the third air valve 61 is electrically connected to the control unit 14. The third air valve 61 drives the airflow of the supply air duct 3 to flow back to the return air duct 2 through the reversing duct 6. Specifically, there are two reversing ducts 6. At the same time, a fourth air valve 21 is provided in the return air duct 2, and the fourth air valve 21 is located between the inlet ends of the two reversing ducts. A fifth air valve 31 is provided in the supply air duct 3, and the fifth air valve 31 is located between the outlet ends of the two reversing ducts. The fourth air valve 21 and the fifth air valve 31 are electrically connected to the control unit 14, respectively.

[0059] In this embodiment, the external reversing channel can operate independently during airflow reversal. When the control unit 14 receives a signal that the temperature and humidity deviation in a certain area of ​​the storage space is large, it will automatically activate the reversing mode. At this time, the third air valve 61 opens, the fourth and fifth air valves close, and the airflow begins to circulate in reverse. The control unit 14 is equipped with an intelligent algorithm that can automatically optimize the time interval and duration of airflow reversal according to the type of storage space and the characteristics of the materials. The reversing channel reverses part of the airflow sent out by the main processing channel and sends it back to the return air channel 2 for circulation, which has significant beneficial effects: First, by utilizing airflow circulation, the amount of external fresh air processed by the air conditioning system is reduced, reducing the cooling or heating load. In conjunction with the bypass and fresh air functions, the equipment can be flexibly adjusted according to different environmental conditions and storage needs during operation, further reducing energy consumption. Second, continuous airflow circulation helps to quickly balance the temperature and humidity in the storage space. With the flexible layout of the external air duct, the processed air can be delivered to all parts of the space more efficiently. Compared with traditional equipment, it can improve the uniformity of temperature and humidity in the storage space.

[0060] This embodiment is an example of modifying Embodiment 3 by adding a reversing channel. In other embodiments, other embodiments in Embodiments 1 to 6 can also be modified accordingly. The core logic, working principle and beneficial effects of the modification are the same as those of this embodiment, and will not be described in detail here.

[0061] It should be noted that the control unit 14, as the core hub of the intelligent operation of the dedicated air conditioner for material storage space in this application, integrates a high-performance microprocessor and multi-channel drive circuit, enabling efficient operation of complex control algorithms. It is equipped with multiple communication interfaces to ensure a closed-loop control circuit with various processing units, air valves, external sensors, and the host computer, achieving stable data interaction. Based on preset temperature and humidity control algorithms and material storage process requirements, the control unit 14 can precisely control each unit and air valve according to real-time data collected by temperature and humidity sensors, combined with preset material storage environment parameter thresholds, dynamically adjusting the return and supply air flow rates to achieve energy-saving operation and precise environmental control of the air conditioning equipment, ensuring that the material storage environment is always in optimal operating conditions.

[0062] Furthermore, the heat exchange unit 12 of this application has two optional configuration options, see [link to relevant documentation] Figure 1 and Figure 2 The system can be configured in two ways: First, a chilled water coil connected to an external chilled water system can be used, with the chilled water coil achieving continuous and stable sensible heat exchange through the external chilled water drainage system. Second, an evaporator connected to an external outdoor unit via refrigerant pipes can be used. The configuration can be flexibly selected based on the temperature, humidity, and material characteristics of the storage environment, effectively meeting the sensible and latent heat exchange requirements under different operating conditions. The air supply unit 13 includes a fan and guide vanes. The adjustable guide vanes effectively drive and guide airflow, ensuring uniform airflow distribution within the material storage space.

[0063] This utility model's special air conditioning equipment for material storage spaces achieves multiple beneficial effects through various improved designs, as detailed below:

[0064] 1. By setting up bypass ventilation ducts and humidification units, combined with closed-loop control of temperature and humidity sensors and control units, temperature and humidity can be controlled separately, avoiding the cooling and heating cancellation of traditional equipment. The cooling, heating and humidification power can be dynamically adjusted to ensure that the temperature and humidity of the storage space are uniform and stable, with higher accuracy.

[0065] 2. The bypass ventilation duct can be installed either internally or externally; when installed internally, the structure is compact and saves space; when installed externally, the length and direction can be flexibly adjusted to adapt to different storage spaces, making it easy to replace the humidification unit and repair the air valve without disassembling the cabinet, and no changes to the internal structure of the cabinet are required during the renovation, thus reducing costs.

[0066] 3. By setting up a fresh air duct, suitable fresh air is introduced to replace part of the return air, reducing the load on the heat exchange unit and further reducing energy consumption; the fresh air and return air can be mixed in advance before the filter unit or in the return air duct.

[0067] 4. The reversing air duct design enables reverse airflow circulation. Combined with intelligent algorithms to optimize circulation parameters, it quickly balances the temperature and humidity within the space, improves uniformity, and reduces regional deviations.

[0068] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.
