Abstract
Description
Technical Field
[0001] This invention belongs to the field of air conditioning and ventilation technology for grain warehouses, and particularly relates to a warehouse temperature and humidity control system. Background Technology
[0002] Temperature and humidity are key factors affecting the quality of stored grain. Excessive temperature and humidity can lead to mold, sprouting, and pest infestation of grain, while suitable temperature and humidity can extend the storage period of grain and maintain its quality.
[0003] In related technologies, grain silo temperature and humidity control systems are mostly ventilation control systems designed for small grain silos. They typically adjust the internal temperature and humidity based on both the external and internal conditions, using ventilation to maintain a suitable environment for the grain and extend its shelf life. However, such systems are not efficient at quickly cooling and dehumidifying the grain, resulting in low ventilation efficiency.

[0058] The following is in conjunction with the attached diagram. Figures 1 to 5 The warehouse temperature and humidity control system provided by this invention will be described in detail.
[0059] See Figure 1The warehouse temperature and humidity control system 100 in this embodiment of the invention may include an ambient temperature and humidity detection device 101, a warehouse temperature and humidity detection device 102, a controller 103, and a movable air conditioning device 104.
[0060] The movable air conditioning device 104 includes multiple movable ventilation components 106 distributed within the warehouse, which includes a storage stack.
[0061] The atmospheric temperature and humidity detection device 101 can be used to detect the primary temperature and primary humidity of the atmosphere.
[0062] The warehouse temperature and humidity detection device 102 can be used to detect the second temperature and second humidity of the air inside the warehouse.
[0063] The ventilation assembly 106 can be used to detect the third temperature and third humidity of the air inside the storage stack, and can also be used to replace the air inside the storage stack.
[0064] The controller 103 can be used to control multiple ventilation components 106 to replace the air in the storage stack based on a first temperature, a first humidity, a second temperature, a second humidity, a third temperature, and a third humidity, so as to regulate the temperature and humidity of the air in the storage stack.
[0065] In this embodiment of the invention, the warehouse can be a large grain storage warehouse, that is, the warehouse temperature and humidity control system 100 provided in this embodiment of the invention can be applied to large storage warehouses, and the storage pile can be various grain piles. By detecting and comparing the temperature and humidity outside the warehouse, inside the warehouse, and inside the grain pile, it is determined whether the temperature and humidity of the grain pile need to be adjusted; by using multiple ventilation components 106 distributed in the warehouse, precise ventilation of the grain pile is achieved, thereby improving the ventilation efficiency of the grain pile and extending the storage time of the grain.
[0066] In some embodiments, such as Figure 2 As shown, the ventilation assembly 106 is tubular and includes a temperature and humidity detection module 201, multiple air vents 202, and a first air exchange fan 203. The first air exchange fan 203 is located at the ventilation opening at the top of the ventilation assembly 106, and the ventilation opening is higher than the storage stack, that is, the ventilation opening at the top of the ventilation assembly 106 connects the interior of the ventilation assembly 106 with the air in the warehouse.
[0067] It is understandable that, in the absence of airflow, there is generally only diffusion between the air in the warehouse, the air in the ventilation unit 106, and the air in the storage pile.
[0068] The temperature and humidity detection module 201 can be used to detect the third temperature and the third humidity.
[0069] In this embodiment, each ventilation assembly 106 includes a temperature and humidity detection module 201, meaning that each ventilation assembly 106 arranged in the warehouse can collect the temperature and humidity of the air at its location. For a certain area of the storage pile, the temperature and humidity data collected by each ventilation assembly 106 in that area may be the same or different. The third temperature includes the temperature data collected by all ventilation assemblies 106, and the third humidity includes the humidity data collected by all ventilation assemblies 106.
[0070] Vent 202 is used to connect the air inside the ventilation assembly 106 and the storage stack.
[0071] Furthermore, the temperature and humidity detection module 201 may include multiple detection units 204, which can be used to detect the fourth temperature and fourth humidity of the air at their location. It is understood that during the operation of the warehouse temperature and humidity control system 100, the ventilation component 106 is typically inserted into the storage pile, ensuring that its vents are above the storage pile. Therefore, the fourth temperature and fourth humidity detected by the detection unit 204 are actually the temperature and humidity of the grain near its location.
[0072] like Figure 2 As shown. Multiple detection units 204 and air vents 202 are disposed at multiple preset heights on the ventilation assembly 106. The multiple detection units 204 are located inside the ventilation assembly 106, and the multiple air vents 202 are distributed on the pipe wall of the ventilation assembly 106. For example, Figure 2 The ventilation assembly 106 shown includes four preset heights, and multiple air holes can be provided on the pipe wall at each preset height of the ventilation assembly 106. For example, four, five, or six air holes can be evenly opened on the pipe wall. The actual number of air holes can be flexibly set according to the diameter of the ventilation assembly 106, and the present invention does not limit this.
[0073] It should be noted that in practical applications, the length of the ventilation component 106 is designed based on the height of the storage pile. When determining the aforementioned preset height value, the height of the storage pile must also be considered, and the specific setting can be combined with the natural heat dissipation capacity of the actual storage pile. For example, the natural heat dissipation capacity of grains, beans, and tubers differs. For varieties with strong heat dissipation capacity, the interval between multiple preset heights can be a first interval; for varieties with weak heat dissipation capacity, the interval between multiple preset heights can be a second interval, with the first interval being larger than the second interval. That is, for grain piles with weak heat dissipation capacity, more layers of vents are set to fully improve ventilation efficiency, allowing the grain in the corresponding location to cool and dehumidify rapidly.
[0074] In this embodiment, the ventilation assembly 106 may further include controllable closing components corresponding one-to-one with the plurality of air holes 202. The controllable closing components are used to control the opening or closing of the corresponding air holes 202. It can be understood that the opening and closing of each air hole 202 is controllable. In practical applications, when the temperature of the air inside the warehouse is lower than the temperature of the storage pile, the temperature of the grain on the surface of the storage pile is very close to the temperature of the air inside the warehouse. However, the temperature of the grain at the bottom of the storage pile may be higher. In this case, it is only necessary to ventilate the grain at the bottom. Therefore, it is only necessary to open the air holes 202 at the bottom of the storage pile, while the air holes 202 at the top of the storage pile can be set to a closed state.
[0075] Accordingly, the ventilation assembly 106 in this embodiment also includes a first control module, which is electrically connected to the controller 103.
[0076] The controller 103 can specifically be used to determine a first instruction based on a first temperature, a first humidity, a second temperature, a second humidity, a plurality of fourth temperatures, and a plurality of fourth humidityes. The first instruction includes an identifier of a target controllable closure, which is a controllable closure at the height of a target location within the storage stack; the target location is the position of the detection unit 204 corresponding to a fourth temperature greater than the first temperature or the second temperature, and the position of the detection unit 204 corresponding to a fourth humidity greater than the first humidity or the second humidity.
[0077] The first control module can be used to control the target controllable closure to open according to a first instruction, so that the corresponding air vent 202 opens; at the same time, it controls the first air exchange fan 203 of the target ventilation assembly 106 to open, so as to replace the air at the target location in the storage pile with the air inside the warehouse. The target ventilation assembly 106 is the ventilation assembly 106 where the controllable closure is located.
[0078] The first air exchange fan 203 can be used to blow air from the vent into the ventilation assembly 106, or to draw air from the ventilation assembly 106 out of the vent into the air in the warehouse.
[0079] In one possible implementation, for locations within the storage stack that require ventilation, air from the warehouse can be blown into the storage stack simply through the ventilation components 106 near those locations. That is, the first air exchange fan 203 of the corresponding ventilation components 106 is controlled to blow air from the warehouse into these ventilation components 106.
[0080] In another possible implementation, for another location within the storage stack requiring ventilation, air from the warehouse can be blown into the storage stack through a portion of the ventilation assembly 106 attached to that other location, while simultaneously air from the storage stack is extracted into the warehouse air through another portion of the ventilation assembly 106 near that other location. That is, while low-temperature or low-humidity air is blown into a location within the storage stack, high-temperature or high-humidity air is simultaneously extracted from a location nearby.
[0081] In the above embodiment, the opening and closing of the air vent 202 is controlled by controlling the controllable closure. When a certain location in the storage stack needs to be ventilated, cooled or dehumidified, the corresponding air vent 202 of the nearest ventilation component 106 is opened first, and then the first air exchange fan 203 of these ventilation components 106 is turned on to blow air with lower temperature and humidity into the location in the storage stack, thereby achieving air exchange.
[0082] In some embodiments of the present invention, the movable air conditioning device 104 may further include multiple tracks, such as... Figure 3 As shown, the multiple tracks include multiple rows of first tracks 301 and multiple columns of second tracks 302 on each row of first tracks 301.
[0083] In this configuration, multiple rows of second tracks 302 on each row of first tracks 301 are parallel to each other and perpendicular to the first track 301 in the horizontal direction; each row of second tracks 302 on each row of first tracks 301 is movably connected to the first track 301. The controller 103 can be used to control the movement of the second tracks 302 along the first track 301 they are on.
[0084] See Figure 4 The ventilation assembly 106 can be movably connected to the second track 302 via a movable support rod 401. The movable support rod 401 can be used to move the ventilation assembly 106 horizontally along the second track 302, horizontally along the second track 302, and vertically. In other words, through the first track 301, the second track 302, and the support rod 401, the ventilation assembly 106 can achieve three-dimensional movement.
[0085] In this embodiment, the controller 103 can also be used to control the ventilation component 106 in the first area to move to the vicinity of the first position and replace the air in the storage pile near the first position. The first position is a location in the storage pile where the temperature difference between the fourth temperature and the first or second temperature is higher than a preset temperature, or where the humidity difference between the fourth humidity and the first or second humidity is higher than a preset humidity; the first area is a region of a preset size surrounding the second position.
[0086] In some embodiments, the warehouse temperature and humidity control system 100 of the present invention may further include a warehouse air replacement system. See also Figure 5 The warehouse air replacement system includes multiple air replacement units 501 arranged on the walls of the warehouse.
[0087] Furthermore, the air displacement unit 501 may include a door switch, a second air displacement fan, and a humidity reduction device.
[0088] The door switch is used to control the opening and closing of the air displacement unit 501, that is, to open or close the ventilation opening of the air displacement unit 501.
[0089] The second air exchange fan is used to replace the air inside the warehouse. This air exchange can be achieved by either blowing air from the atmosphere into the warehouse or by extracting air from inside the warehouse into the atmosphere.
[0090] A humidity reduction device is used to reduce the humidity of air entering the warehouse from the outside. For example, the humidity reduction device can be a controllable device with a drying function, or a controllable device with a desiccant. The present invention does not limit the type of humidity reduction device.
[0091] In this embodiment, the warehouse air replacement system also includes a second control module, which is electrically connected to the controller 103.
[0092] The controller 103 can also be used to determine a second command based on wind speed, a first temperature, a first humidity, a second temperature, a second humidity, a third temperature, and a third humidity.
[0093] The second control module can be used to control the opening and closing of the door, the second air exchange fan, and the humidity reduction device according to the second instruction.
[0094] In the above embodiment, the warehouse air replacement system integrates multiple air replacement units 501 and a second control module, enabling ventilation control between the inside and outside of the warehouse. Specifically, the controller 103 can calculate temperature and humidity data to determine whether the air inside the warehouse needs adjustment. If adjustment is required, it can send a control command (second command) to the second control module of the warehouse air replacement system. Subsequently, the second control module controls the opening and closing of the doors of the corresponding air replacement units 501, the second air replacement fan, and the opening and closing of the humidity reduction device according to the control command.
[0095] In some embodiments, the warehouse temperature and humidity control system 100 of the present invention may further include a wind measuring device for detecting the wind speed outside the warehouse.
[0096] Specifically, the wind measuring device can be an anemometer, which is installed outside the warehouse at a preset distance. This anemometer can detect both wind speed and wind direction.
[0097] Next, for several situations where air conditioning is required for storage stacks, embodiments of the present invention provide specific control methods for the warehouse temperature and humidity control system 100.
[0098] In some embodiments, the controller 103 may specifically be used for:
[0099] If the detected wind speed is less than or equal to the preset wind speed, then
[0100] When the first temperature, second temperature, and third temperature are equal, and the first humidity, second humidity, and third humidity are equal, control the opening and closing of the door, the second air exchange fan, and the humidity reduction device to be turned on to reduce the humidity of the air inside the warehouse; control multiple ventilation components 106 to replace the air in the storage pile with the air inside the warehouse.
[0101] When the third temperature is greater than the first and second temperatures, or the third humidity is greater than the first and second humidity, the control door opens, the second air exchange fan and humidity reduction device close, and multiple ventilation components 106 replace the air in the storage pile with the air inside the warehouse.
[0102] When the first temperature is lower than the second and third temperatures, or the first humidity is lower than the second and third humidity, the control door and the second air exchange fan are turned on, the humidity reduction device is turned off, and the multiple ventilation components 106 are controlled to replace the air in the storage pile with the air inside the warehouse.
[0103] When the second temperature is lower than the first and third temperatures, or the second humidity is lower than the first and third humidity, the control door, the second air exchange fan, and the humidity reduction device are turned off, and the multiple ventilation components 106 are controlled to replace the air in the storage pile with the air inside the warehouse.
[0104] In the above embodiment, under the premise that there is no wind or the wind speed is not fast enough to blow outside air into the warehouse, the controller 103 needs to control the second air exchange fan in the air exchange unit 501 to turn on, so as to ensure that the outside air and the air inside the warehouse can circulate quickly.
[0105] In other embodiments, the controller 103 may specifically be used for:
[0106] If the detected wind speed is greater than the preset wind speed, then
[0107] When the first temperature, second temperature, and third temperature are equal, and the first humidity, second humidity, and third humidity are equal, control the opening and closing of the door and the opening of the humidity reduction device to reduce the humidity of the air inside the warehouse; control multiple ventilation components 106 to replace the air in the storage pile with the air inside the warehouse.
[0108] When the third temperature is greater than the first and second temperatures, or the third humidity is greater than the first and second humidity, the control door opens, the second air exchange fan and humidity reduction device close, and multiple ventilation components 106 replace the air in the storage pile with the air inside the warehouse.
[0109] When the first temperature is lower than the second and third temperatures, or the first humidity is lower than the second and third humidity, the control door opens, the control second air exchange fan and humidity reduction device closes, and the control multiple ventilation components 106 replace the air in the storage pile with the air inside the warehouse.
[0110] When the second temperature is lower than the first and third temperatures, or the second humidity is lower than the first and third humidity, the control door, the second air exchange fan, and the humidity reduction device are turned off, and the multiple ventilation components 106 are controlled to replace the air in the storage pile with the air inside the warehouse.
[0111] In the above embodiment, provided that the outside wind speed is sufficient to blow outside air into the warehouse, the controller 103 will control the second air exchange fan in the air exchange unit 501 to close, allowing outside air to naturally enter the warehouse, while also achieving the effect of energy saving and consumption reduction.
[0112] When the temperature and humidity of the air inside the storage pile and the air inside the warehouse are the same and lower than the temperature and humidity of the outside air, the warehouse temperature and humidity control system 100 does not need to regulate the air inside the warehouse. Specifically, the controller 103 is used to control the opening and closing of the door, the second air exchange fan, the humidity reduction device, and multiple ventilation components 106 to shut down when the third temperature is equal to the second temperature, the third humidity is equal to the second humidity, and the third temperature is lower than the first temperature and the third humidity is lower than the first humidity.
[0113] This invention also provides the adjustment process of the warehouse temperature and humidity control system 100 under 14 operating conditions. The relationship between the magnitude of the detection data corresponding to each operating condition, as well as the working status of the door opening / closing, the second air exchange fan, the humidity reduction device, and the ventilation component 106, are shown in Table 1. In Table 1, wind speed "N" indicates wind speed less than or equal to the preset wind speed, and wind speed "Y" indicates wind speed greater than the preset wind speed; "ON" indicates the on state, and "OFF" indicates the off state; T1, T2, and T3 represent the first temperature, second temperature, and third temperature, respectively; RH1, RH2, and RH3 represent the first humidity, second humidity, and third humidity, respectively. In operating conditions 1 and 8, the values of (T1, RH1), (T2, RH2), and (T3, RH3) are all "E", indicating that the first temperature, second temperature, and third temperature are equal, and the first humidity, second humidity, and third humidity are also equal. In other operating conditions, "L" indicates that the corresponding temperature is lower than either of the other two temperatures and the corresponding humidity is lower than either of the other two temperatures, while "H" indicates that the corresponding temperature is higher than either of the other two temperatures and the corresponding humidity is higher than either of the other two temperatures.

[0115]
[0116] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 1, the temperature and humidity at the three locations (atmosphere, inside the warehouse, and storage stack) are equal, and the outside wind force is insufficient. At this time, the door opening / closing, the second air exchange fan, and the humidity reduction device are all in the open state. The second air exchange fan located on one side of the warehouse can blow air from outside the warehouse into the warehouse, and the air blown into the warehouse becomes low-humidity air after passing through the humidity reduction device. The second air exchange fan located on the other side of the warehouse can extract the air inside the warehouse to the outside, thereby reducing the humidity of the air inside the warehouse. At the same time, with the ventilation component 106 open (the first air exchange fan is open, and the air vents are open), the low-humidity air entering the warehouse can also be blown into the storage stack, thereby replacing the original air in the storage stack with low-humidity air, achieving the effect of ventilation and dehumidification of the storage stack.
[0117] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 2, the temperature and humidity of the storage pile are relatively high. At this time, the door opening and closing mechanism and the ventilation component 106 are in the open state, while the second air exchange fan and the humidity reduction device are in the closed state. The ventilation component 106 blows low-temperature and humid air into the storage pile to ventilate, cool, and dehumidify the storage pile.
[0118] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 3, the temperature and humidity of the air inside the warehouse are relatively high, requiring cooling and dehumidification. At this time, the door opening / closing and the second air exchange device are in the open state, while the humidity reduction device and the ventilation assembly 106 are in the closed state. A second air exchange fan located on one side of the warehouse blows outside air into the warehouse, while a second air exchange fan located on the other side of the warehouse draws air from inside the warehouse to the outside. This utilizes outside air to replace the air inside the warehouse, reducing the temperature and humidity of the air inside the warehouse.
[0119] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 4, the temperature and humidity of the air in the atmosphere are relatively high. At this time, there is no need to regulate the air inside the warehouse. Therefore, the door opening and closing, the second air exchange fan, and the humidity reduction device are all in the closed state.
[0120] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 5, the temperature and humidity of the air in the atmosphere are relatively low. At this time, the door opening and closing device and the second air replacement device are in the open state, and the humidity reduction device is in the closed state. The air with high temperature and humidity in the warehouse can be replaced with air with low temperature and humidity. At the same time, the ventilation component 106 is also in the open state, thereby replacing the air in the storage pile with air with low temperature and humidity.
[0121] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 6, the temperature and humidity of the air inside the storage pile are relatively low. At this time, there is no need to regulate the air inside the storage pile, so the door opening and closing, the second air exchange fan, and the humidity reduction device are all in the off state.
[0122] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 7, the temperature and humidity of the air inside the warehouse are relatively low. At this time, the door opening and closing device, the second air replacement device, and the humidity reduction device are all in the closed state, and the ventilation component 106 is in the open state, thereby blowing the air inside the warehouse into the storage pile and reducing the temperature and humidity of the storage pile.
[0123] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 8, the temperature and humidity at the three locations (atmosphere, inside the warehouse, and storage stack) are equal, and external wind can blow air into the warehouse. At this time, the door opening / closing and humidity reduction devices are both on, and the second air exchange fan does not need to be turned on. Air from the windward side of the warehouse can be directly blown into the warehouse, and the air blown into the warehouse becomes low-humidity air after passing through the humidity reduction device. The air inside the warehouse can enter the atmosphere through the vent of the air exchange unit 501 located on the leeward side of the warehouse, thereby reducing the humidity of the air inside the warehouse. At the same time, with the ventilation component 106 on, the low-humidity air entering the warehouse can also be blown into the storage stack, thereby replacing the original air in the storage stack with low-humidity air, achieving the effect of ventilation and dehumidification of the storage stack.
[0124] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 9, the temperature and humidity of the storage pile are relatively high, and the outside wind can blow air into the warehouse. At this time, the door opening and closing and the ventilation component 106 are in the open state, and the second air exchange fan and humidity reduction device are in the closed state. The ventilation component 106 blows low-temperature and humid air into the storage pile to ventilate, cool and dehumidify the storage pile.
[0125] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 10, the temperature and humidity of the air inside the warehouse are relatively high, and external wind can blow air into the warehouse. At this time, the door is open, and the second air exchange fan, humidity reduction device, and ventilation assembly 106 are closed. Air on the windward side of the warehouse can be directly blown into the warehouse, and the original air inside the warehouse can enter the atmosphere through the ventilation opening of the air exchange unit 501 located on the leeward side of the warehouse, thereby reducing the humidity of the air inside the warehouse.
[0126] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 11, the temperature and humidity of the air in the atmosphere are relatively high, and the outside wind can blow air into the warehouse. At this time, there is no need to regulate the air inside the warehouse, so the door opening and closing, the second air exchange fan, and the humidity reduction device are all in the off state.
[0127] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 12, the temperature and humidity of the air in the atmosphere are relatively low, and the outside wind can blow air into the warehouse. At this time, the door is open, the second air exchange device and the humidity reduction device are closed, and the air with high temperature and humidity in the warehouse can be replaced with air with lower temperature and humidity. At the same time, the ventilation component 106 is also open, thereby replacing the air in the storage pile with air with lower temperature and humidity.
[0128] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 13, the temperature and humidity of the air inside the storage pile are relatively low. At this time, there is no need to regulate the air inside the storage pile, so the door opening and closing, the second air exchange fan, and the humidity reduction device are all in the off state.
[0129] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in operating condition 14, the temperature and humidity of the air inside the warehouse are relatively low. At this time, the door opening and closing device, the second air replacement device, and the humidity reduction device are all in the closed state, and the ventilation component 106 is in the open state, thereby blowing the air inside the warehouse into the storage pile and reducing the temperature and humidity of the storage pile.
[0130] The warehouse temperature and humidity control system 100 provided in this embodiment of the invention detects the temperature and humidity of the air outside the warehouse, inside the warehouse, and inside the storage pile to determine whether the air inside the storage pile needs to be replaced, and can also determine whether the air inside the warehouse needs to be replaced. Multiple ventilation components 106 distributed inside the warehouse are used to replace the air in the storage pile, thereby providing timely ventilation inside the storage pile; multiple air replacement units 501 are used to replace the air inside the warehouse. Moreover, the ventilation components 106 can move in three dimensions, enabling rapid and precise ventilation adjustment at designated locations within the storage pile, improving the cooling and dehumidification efficiency of the storage pile inside the warehouse, and effectively extending the storage time of the stored goods.
