Description

Technical Field

[0001] This invention relates to the field of environmental control technology, and in particular to a warehouse environmental control method, air conditioner, and storage medium. Background Technology

[0002] With the improvement of agricultural planting technology, my country now faces a large grain storage problem. The storage time of grain is closely related to the temperature and humidity changes in the grain warehouse environment. Therefore, the control of temperature and humidity in grain warehouses is particularly important. Traditional grain warehouse air conditioners use air valves to ventilate the grain warehouse to achieve cooling and dehumidification, but the ventilation method is singular and cannot be adjusted independently.

[0013] When the first difference is less than or equal to the second difference, the air conditioner is controlled to execute the air circulation scheme in the warehouse;

[0014] When the first difference is greater than the second difference, the air conditioner is controlled to execute the air circulation scheme inside and outside the warehouse.

[0015] Optionally, determining the first difference between the temperature and / or humidity value inside the warehouse and the preset temperature and / or humidity value includes:

[0054] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Traditional grain warehouse air conditioners only use the air inside or outside the grain warehouse for circulating cooling and dehumidification. The air valves at the air intake are manually operated electric valves, which cannot be automatically adjusted and lack real-time performance and accuracy.

[0056] Therefore, the present invention aims to control the temperature and humidity of a warehouse by automatically controlling the air conditioner to perform air circulation inside the warehouse or circulation between the outside air and the inside air after comparing the temperature and humidity inside and outside the warehouse with the temperature and humidity set by the user.

[0057] Reference Figure 1 The diagram illustrates a flowchart of a warehouse environment control method according to an embodiment of the present invention. The warehouse is equipped with air conditioning, and the method may specifically include the following steps:

[0058] Step 101: Obtain preset temperature and / or humidity information, temperature and / or humidity information inside the warehouse, and temperature and / or humidity information outside the warehouse.

[0059] A warehouse is a storage room for storing goods. This invention does not impose specific restrictions on the types of goods stored in a warehouse. For example, a warehouse can be a grain warehouse.

[0060] Temperature and humidity sensors can be installed inside and / or outside the warehouse to obtain temperature and / or humidity information inside and outside the warehouse.

[0061] The preset temperature and / or humidity information refers to the target temperature and / or humidity levels to which the warehouse will be adjusted. This can be user-defined or default. For example, if the warehouse stores wheat, the user can set the preset temperature to 10°C and the preset humidity to 60% based on the wheat's storage conditions.

[0062] Step 102: Compare the temperature and / or humidity information inside the warehouse and the temperature and / or humidity information outside the warehouse with preset temperature and / or humidity information respectively, and obtain the comparison results.

[0063] The temperature and / or humidity information inside the warehouse can be compared with preset temperature and / or humidity information to determine a first difference between the two. Similarly, the temperature and / or humidity information outside the warehouse can be compared with preset temperature and / or humidity information to determine a second difference.

[0064] For example, if the temperature inside the warehouse is 10℃, the temperature outside the warehouse is 5℃, and the preset temperature is 15℃, then the first difference between the temperature inside the warehouse and the preset temperature is 5℃, and the second difference between the temperature outside the warehouse and the preset temperature is 10℃.

[0065] Alternatively, if the temperature inside the warehouse is 10℃ and the humidity inside the warehouse is 60%, and the preset temperature is 15℃ and the preset humidity is 65%, then the first difference between the temperature and humidity inside the warehouse and the temperature and humidity outside the warehouse is 5 (temperature difference) + 5 (humidity difference) = 10.

[0066] The first gap can characterize the degree of similarity between the temperature and / or humidity information inside the warehouse and the preset temperature and / or humidity information, and the second gap can characterize the degree of similarity between the temperature and / or humidity information outside the warehouse and the preset temperature and / or humidity information.

[0067] Step 103: Based on the comparison results, control the air conditioner to execute either the air circulation scheme inside the warehouse or the air circulation scheme between the inside and outside of the warehouse.

[0068] Warehouse air circulation refers to the process of air circulating within the warehouse.

[0069] Warehouse air circulation refers to the process of circulating air between the inside and outside of a warehouse. For example, air from outside is introduced into the warehouse while air inside is exhausted, so that air circulates between the two.

[0070] When the temperature and / or humidity information inside the warehouse is closer to the preset temperature and / or humidity information than the temperature and / or humidity information outside the warehouse, the air conditioning can be controlled to execute the air circulation scheme inside the warehouse. Conversely, the air circulation scheme between the inside and outside of the warehouse can be executed. This allows the temperature and / or humidity inside the warehouse to reach the preset temperature and / or humidity more quickly, and also saves energy.

[0071] Continuing with the example above, if the temperature inside the warehouse differs from the preset temperature by 5°C, and the temperature outside the warehouse differs from the preset temperature by 10°C, then the air conditioner can be controlled to execute the air circulation scheme inside the warehouse.

[0072] The embodiments of the present invention can automatically implement targeted air conditioning programs for either the air circulation inside the warehouse or the air circulation between the warehouse and the outside of the warehouse based on the comparison results of the temperature and / or humidity information inside the warehouse with preset temperature and / or humidity information, as well as the comparison results of the temperature and / or humidity information outside the warehouse with preset temperature and / or humidity information, thereby making the ventilation methods inside the warehouse more accurate and diverse.

[0073] Reference Figure 2 The diagram illustrates a flowchart of another warehouse environment control method provided by an embodiment of the present invention. The warehouse is equipped with an air conditioner, which includes a compressor, an evaporator, an air intake vent inside the warehouse, and an air intake vent outside the warehouse. A first valve is installed at the air intake vent inside the warehouse, and a second valve is installed at the air intake vent outside the warehouse. The method may specifically include the following steps:

[0074] Step 201: Obtain preset temperature and / or humidity information, temperature and / or humidity information inside the warehouse, and temperature and / or humidity information outside the warehouse; the temperature information includes temperature values, and the humidity information includes humidity values.

[0075] Step 202: Determine the first difference between the temperature and / or humidity value inside the warehouse and the preset temperature and / or humidity value.

[0076] When only the temperature inside the warehouse is controlled, the difference between the temperature value inside the warehouse and the preset temperature value can be used as the first difference. When only the humidity inside the warehouse is controlled, the difference between the humidity value inside the warehouse and the preset humidity value can be used as the first difference. When both the temperature and humidity inside the warehouse are controlled, the sum of the differences between the temperature value inside the warehouse and the preset temperature value, and the differences between the humidity value inside the warehouse and the preset humidity value, can be used as the first difference.

[0077] For ease of comparison, all differences are numbers greater than or equal to 0.

[0078] In one embodiment, when both temperature and humidity within the warehouse are simultaneously regulated, the first difference can also be determined according to the following formula:

[0079] Q1 = a × |Tu-Ti| + b × |Wu-Wi|,

[0080] Where Q1 is the first difference, a is the first weighting coefficient, b is the second weighting coefficient, Tu is the preset temperature value, Ti is the temperature value inside the warehouse, Wu is the preset humidity value, and Wi is the humidity value inside the warehouse.

[0081] The first difference is obtained by multiplying the absolute value of the difference between the preset temperature value and the warehouse temperature value by a first weighting coefficient, and then adding the product of the absolute value of the difference between the preset humidity value and the warehouse humidity value by a second weighting coefficient. The first and second weighting coefficients can be set according to the storage requirements of the items in the warehouse.

[0082] Step 203: Determine a second difference between the outside temperature and / or humidity value and the preset temperature and / or humidity value.

[0083] Step 203 is similar to step 202.

[0084] In one embodiment, when both temperature and humidity within the warehouse are simultaneously controlled, the second difference can also be determined according to the following formula:

[0085] Q2 = a × |Tu-Tj| + b × |Wu-Wj|,

[0086] Where Q2 is the second difference, a is the first weighting coefficient, b is the second weighting coefficient, Tu is the preset temperature value, Tj is the temperature value outside the warehouse, Wu is the preset humidity value, and Wj is the humidity value outside the warehouse.

[0087] Step 204: When the first difference is greater than the second difference, close the first valve and open the second valve, and control the compressor and evaporator to run at their maximum frequencies.

[0088] When the first difference is greater than the second difference, it indicates that the outside temperature and / or humidity values ​​are closer to the preset values. At this point, the air conditioning system can be controlled to execute the warehouse air circulation scheme. The warehouse air circulation scheme specifically includes: closing the first valve to stop the air conditioning system from drawing air from the warehouse air intake; opening the second valve, which can be fully open, allowing the air conditioning system to draw air from the outside air intake and then deliver air into the warehouse through the air outlet, thus circulating air between the outside and inside of the warehouse; and controlling the air conditioning compressor and evaporator to operate at their maximum frequency to quickly bring the warehouse temperature and / or humidity values ​​to the preset values.

[0089] Step 205: When the first difference is less than or equal to the second difference, close the second valve and open the first valve, and control the opening angle of the first valve and the operating frequency of the compressor and evaporator according to the temperature and / or humidity information in the warehouse, as well as the preset temperature and / or humidity information.

[0090] When the first difference is less than or equal to the second difference, it indicates that the temperature and / or humidity values ​​inside the warehouse are closer to the preset temperature and / or humidity values. At this point, the air conditioner can be controlled to execute the air circulation program inside the warehouse. When the air conditioner executes the air circulation program inside the warehouse, the opening angle of the first valve and the operating frequency of the compressor and evaporator can be controlled based on the temperature and / or humidity values ​​inside the warehouse, as well as the preset temperature and / or humidity values.

[0091] In this embodiment of the invention, the air conditioner can be controlled to execute either an internal / external air circulation scheme or an internal air circulation scheme based on the magnitude of a first difference and a second difference. When the air conditioner executes the internal / external air circulation scheme, the second valve of the air conditioner can be fully opened, and the compressor and evaporator of the air conditioner operate at maximum frequency to quickly bring the temperature and / or humidity values ​​inside the warehouse to the preset temperature and / or humidity values. When the air conditioner executes the internal air circulation scheme, the opening angle of the first valve and the operating frequency of the compressor and evaporator can be precisely controlled based on the internal temperature and / or humidity values, as well as the preset temperature and / or humidity values, so that the temperature and / or humidity values ​​inside the warehouse can reach the preset temperature and / or humidity values ​​more accurately.

[0092] In this embodiment of the invention, step 205 may specifically include sub-steps S11-S18:

[0093] Sub-step S11: When the temperature and humidity information in the warehouse meet the first preset conditions, the first preset conditions include: the difference between the temperature value in the warehouse and the preset temperature value is less than the temperature threshold, and the difference between the humidity value in the warehouse and the preset humidity value is less than the humidity threshold. The comprehensive temperature and humidity value is determined according to the following formula: Q3=a×(Tu-Ti)+b×(Wu-Wi), where Q3 is the comprehensive temperature and humidity value, a is the first weighting coefficient, b is the second weighting coefficient, Tu is the preset temperature value, Ti is the temperature value in the warehouse, Wu is the preset humidity value, and Wi is the humidity value in the warehouse.

[0094] When the air conditioner is determined to execute the air circulation scheme in the warehouse, it can be further determined whether the temperature and humidity information in the warehouse meet the first preset conditions, that is, whether the difference between the temperature value in the warehouse and the preset temperature value is less than the temperature threshold, and whether the difference between the humidity value in the warehouse and the preset humidity value is less than the humidity threshold.

[0095] For example, if the warehouse temperature is 10℃ and the warehouse humidity is 60%, the preset temperature is 11℃ and the preset humidity is 62%, the temperature threshold is 2℃ and the humidity threshold is 3%, then the difference between the warehouse temperature and the preset temperature is 1℃, which is less than the temperature threshold of 2℃; the difference between the warehouse humidity and the preset humidity is 2%, which is less than the humidity threshold of 3%. In this case, the warehouse temperature and humidity information is determined to meet the first preset condition. If the warehouse temperature and humidity information meet the first preset condition, then the combined temperature and humidity value can be calculated.

[0096] If the temperature and humidity information in the warehouse does not meet the first preset condition, the first valve can be opened to a certain angle, for example, the first valve can be fully opened, so that the air conditioner compressor and evaporator can run at the maximum frequency.

[0097] Sub-step S12: When the combined temperature and humidity value is less than 0, increase the opening angle of the first valve by a preset angle.

[0098] If the combined temperature and humidity value is less than 0, it means that the temperature and humidity in the warehouse environment are greater than the user-set temperature and humidity values. In this case, the voltage can be increased by 1V, and the first valve actuator will control the opening degree (opening angle) of the first valve to increase, thereby reducing the temperature and humidity in the warehouse.

[0099] Simultaneously, the opening information of the first valve can be fed back through an angle sensor installed on the first valve actuator. If the angle sensor on the first valve actuator detects that the opening of the first valve is already at its maximum or has reached its minimum opening (50%), the opening of the first valve will be maintained unchanged to prevent damage to the first valve or the first valve actuator.

[0100] Sub-step S13: When the combined temperature and humidity value is equal to 0, maintain the opening angle of the first valve.

[0101] If the combined temperature and humidity value is 0, it means that the temperature and humidity in the warehouse are equal to the user-set temperature and humidity. In this case, the opening angle of the first valve should be maintained.

[0102] Sub-step S14: When the combined temperature and humidity value is greater than 0, reduce the opening angle of the first valve by a preset angle.

[0103] If the combined temperature and humidity value is greater than 0, it means that the temperature and humidity of the warehouse environment are less than the user-set temperature and humidity values. In this case, the voltage can be reduced by 1V, and the first valve actuator can control the opening of the first valve to increase or decrease, thereby increasing the temperature and humidity of the warehouse.

[0104] Similarly, an angle sensor installed on the first valve actuator can provide feedback on the opening degree of the first valve and control the opening degree of the first valve to prevent damage to the first valve or the first valve actuator.

[0105] Sub-step S15: When the temperature and humidity information in the warehouse meet the first preset conditions, and the temperature value in the warehouse is greater than the preset temperature value, control the compressor to run at the first frequency.

[0106] Sub-step S16: When the temperature and humidity information in the warehouse meet the first preset condition, and the temperature value in the warehouse is less than the preset temperature value, control the compressor to run at the second frequency; the first frequency is greater than the second frequency.

[0107] For example, the first frequency can be 60-80Hz, and the second frequency can be 50-60Hz.

[0108] Sub-step S17: When the temperature and humidity information in the warehouse meet the first preset condition, and the humidity value in the warehouse is greater than the preset humidity value, control the evaporator to run at the third frequency.

[0109] Sub-step S18: When the temperature and humidity information in the warehouse meet the first preset condition, and the humidity value in the warehouse is less than the preset humidity value, control the evaporator to operate at the fourth frequency; the third frequency is greater than the fourth frequency.

[0110] For example, the third frequency can be 60-80Hz, and the fourth frequency can be 50-60Hz.

[0111] According to the temperature and humidity information in the warehouse, and the preset temperature and humidity information, the opening degree of the first valve and the operating frequency of the compressor and evaporator fan are adjusted accordingly. This can speed up the adjustment of the warehouse air conditioner to change the temperature and humidity of the warehouse, reduce the energy consumption of the warehouse air conditioner, and as the frequency of the compressor and evaporator fan changes, the temperature and humidity of the warehouse will be closer to the user's set temperature and humidity, thereby achieving precise temperature and humidity control.

[0112] Reference Figure 3 This diagram illustrates an air conditioning structure according to an embodiment of the present invention. The air conditioner includes an air outlet, an internal air intake, an external air intake, and an evaporator. An internal air valve (first valve) and an internal air valve actuator (first valve actuator) are provided at the internal air intake; the internal air valve actuator controls the opening degree of the internal air valve. An external air valve (second valve) and an external air valve actuator (second valve actuator) are provided at the external air intake; the external air valve actuator controls the opening degree of the external air valve. When the internal air valve is opened and the external air valve is closed, air inside the warehouse is drawn into the air conditioner through the internal air intake and then flows into the warehouse through the air outlet. When the external air valve is opened and the internal air valve is closed, air outside the warehouse is drawn into the air conditioner through the external air intake and then flows into the warehouse through the air outlet.

[0113] Reference Figure 4which shows a flowchart of a warehouse environment control method provided by an embodiment of the present invention. The user-set temperature and humidity can be acquired, and the temperature and humidity inside the granary and the temperature and humidity outside the granary can be detected in real time. A comparison is performed every 10 minutes to determine whether the temperature and humidity inside the granary are closer to the user-set temperature and humidity than the temperature and humidity outside the granary. If yes, the inner granary circulation (air circulation inside the warehouse) is executed, and if not, the outer granary circulation (air circulation inside and outside the warehouse) is executed.

[0114] When the outer granary circulation is executed, the inner air damper can be closed, the outer air damper can be opened to the maximum opening, and the compressor and the evaporator of the granary air conditioner operate at the maximum frequency.

[0115] When the inner granary circulation is executed, the outer air damper can be closed, the inner air damper can be fully opened, the evaporator and the compressor operate at the maximum frequency, and then it is further determined whether the temperature and humidity inside the granary meet a first preset condition: |Ti-Tu|<2°C and |Wi-Wu|<3%, where Tu is the preset temperature value, Ti is the temperature value inside the granary, Wu is the preset humidity value, and Wi is the humidity value inside the granary. If the condition is not met, the opening of the inner air damper remains unchanged, and the frequencies of the evaporator and the compressor remain unchanged. If the condition is met, the evaporator, the compressor and the inner air damper valve of the granary are precisely controlled. The precise control specifically includes controlling the operating frequencies of the evaporator and the compressor according to the following 4 modes:

[0116] Mode A: Ti>Tu, Wi>Wu, the evaporator operates at 60-80Hz, and the compressor operates at 60-80Hz;

[0117] Mode B: Ti>Tu, Wi<Wu, the evaporator operates at 50-60Hz, and the compressor operates at 60-80Hz;

[0118] Mode C: Ti<Tu, Wi>Wu, the evaporator operates at 60-80Hz, and the compressor operates at 50-60Hz;

[0119] Mode D: Ti<Tu, Wi>Wu, the evaporator operates at 50-60Hz, and the compressor operates at 50-60Hz.

[0120] When Ti=Tu, the frequency of the compressor remains unchanged, and when Wi=Wu, the frequency of the evaporator remains unchanged.

[0121] At the same time, it is determined whether the opening of the inner air damper valve reaches the maximum or minimum. If yes, the angle of the inner air damper valve remains unchanged. If not, it is determined whether the temperature and humidity inside the granary are greater than the user-set temperature and humidity, that is, it is determined whether the comprehensive value of the temperature and humidity inside the granary is less than 0. If the temperature and humidity inside the granary are greater than the user-set temperature and humidity, the opening of the inner air damper valve is increased. If the temperature and humidity inside the granary are less than the user-set temperature and humidity, the opening of the inner air damper valve is decreased.

[0122] When precisely controlling the evaporator, compressor, and internal air valves of the grain silo, the operation management of the evaporator and compressor, and the opening degree of the internal air valves are determined every 10 minutes.

[0123] The comparison cycle can be changed according to the actual application. If the grain warehouse is small and the temperature and humidity change frequently, the comparison cycle can be shortened and the comparison frequency increased. If the grain warehouse is large and the temperature and humidity change is stable, the comparison cycle can be lengthened and the comparison frequency reduced, thereby reducing energy consumption.

[0124] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

[0125] Reference Figure 5 The diagram illustrates a structural block diagram of an air conditioner according to an embodiment of the present invention. The air conditioner may specifically include the following modules:

[0126] The information acquisition module 301 is used to acquire preset temperature information and / or humidity information, temperature information and / or humidity information inside the warehouse, and temperature information and / or humidity information outside the warehouse.
