Description

Technical Field

[0002] In many equipment applications involving water pumps, such as air coolers and humidifiers, effective control of water pump flow rate has always been a critical issue that needs to be addressed. Traditional water pump flow control methods have significant drawbacks, relying heavily on preset fixed parameters or manual adjustment. This approach has strong limitations. In actual operation, especially in devices like air coolers, the water level in the storage tank is constantly changing, directly affecting the pump's head and flow rate requirements. Because traditional control methods cannot dynamically and accurately adjust the pump's output flow rate based on real-time changes in water level, low energy efficiency often occurs during operation, resulting in significant energy waste. Furthermore, inaccurate flow control can lead to equipment instability or even malfunction, impacting overall performance and equipment lifespan. Furthermore, when matching equipment and water pumps of different models, the lack of universality of traditional control methods often necessitates customized design for specific models. This undoubtedly increases the overall production cost and extends the production cycle, while also causing numerous inconveniences in later maintenance and parts replacement, severely restricting the promotion, application, and technological upgrading of related equipment in the market.

[0056] 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.

[0057] Flow rate (Q) refers to the volume of fluid passing through a cross-section per unit time. Velocity (v) refers to the distance the fluid travels per unit time. For a given pipe or channel, the relationship between them can be expressed by the formula Q = A * v, where is the cross-sectional area of ​​the pipe. That is, with a fixed cross-sectional area, flow rate is directly proportional to velocity. For example, when the velocity of a water pump increases, if the cross-sectional area of ​​the pipe remains constant, the flow rate of the water pump will also increase accordingly.

[0058] A water-cooled air conditioner, also known as an eco-friendly air conditioner, water-cooled air conditioner, energy-saving air conditioner, or simply a cooler, is a popular cooling device in modern summers. Water-cooled air conditioners utilize the principle of natural cool air, cooling through the physical phenomenon of water evaporation absorbing heat. Specifically, a circulating water pump circulates water from a tank to an evaporator filter, and then a fan draws in indoor air and blows it over the evaporator filter. During evaporation, the water absorbs heat from the air, resulting in cool airflow. A typical water-cooled air conditioner's main structure includes an evaporator filter, a fan, a water circulation system, and an electronic control unit to adjust the airflow. The water circulation system mainly includes a water tank and a water pump.

[0059] One of the core concepts of this invention is to use a preset function of water level and flow rate to calculate the current water pump flow rate by real-time monitoring of the water level, and then further control the water pump flow rate in real time based on the calculated current flow rate and the preset optimal flow rate.

[0060] Reference Figure 1 The diagram illustrates a step flowchart of an embodiment of a water pump flow control method for a cooling fan according to the present invention, which may specifically include the following steps:

[0061] Step 101: Obtain the water level in the water storage tank;

[0062] The first step is to determine the water level in the outlet tank, which is the foundation for the following steps.

[0063] In one example, the water level in the outlet tank can be obtained by a sensor; for example, a hydrostatic water level sensor, an ultrasonic water level sensor, and a capacitive water level sensor. Other types of sensors can also be used to obtain the water level, and this embodiment of the invention does not limit this.

[0064] Step 102: When the water level is higher than the preset water level, determine the current flow rate of the water pump based on the water level and the preset water level.

[0065] In this step, the water level in the storage tank needs to be monitored continuously or periodically, as this is the fundamental data for flow control. The specific monitoring method can be dynamically set according to different products and business operations, whether it is continuous monitoring or monitoring at a certain time period.

[0066] The preset water level is a pre-defined threshold used to determine when the water pump flow rate needs to be adjusted. When the actual water level exceeds this preset value, the corresponding adjustment logic is executed.

[0067] Step 103: Determine the reference pump flow rate based on the current flow rate of the water pump and the preset standard flow rate;

[0068] The current flow rate is calculated from step 102 and represents the flow rate that the pump should output at the current water level. The preset standard flow rate is the flow rate that the pump should output under ideal or standard conditions, and is the target value for flow control.

[0069] Step 104: Control the flow rate of the water pump according to the reference water pump flow rate, so that the flow rate of the water pump is adjusted to the preset standard flow rate.

[0070] The reference pump flow rate is calculated in step 103 and represents the pump flow rate required to achieve the preset standard flow rate. Based on the reference pump flow rate, the actual pump flow rate is changed by adjusting the impeller speed. By controlling the pump flow rate, the system can gradually bring the actual pump output flow rate closer to and eventually reach the preset standard flow rate, thereby achieving precise flow control.

[0071] First, by acquiring the water level in the storage tank and determining the current flow rate of the water pump based on the water level, a preset water level, and a preset flow function, the actual flow rate of the water pump at different water levels can be monitored in real time and with precision. This effectively solves the problems of inflexibility and real-time response capability of traditional control methods, allowing the water pump flow rate to be flexibly adjusted according to changes in water level, thereby significantly improving energy utilization efficiency, avoiding energy waste caused by improper flow control, ensuring the stability of equipment operation, and reducing the risk of adverse effects on normal equipment operation due to abnormal flow. Second, by determining the reference water pump flow rate based on the current water pump flow rate, a preset standard flow rate, and a preset flow velocity function, and then controlling the water pump flow rate to adjust the flow rate to the preset standard flow rate, precise control of the water pump flow rate is achieved. This precise control feature helps improve the versatility between different water pump models, eliminating the need for customized designs for different models, greatly reducing the overall production cost, improving the market competitiveness and adaptability of the product, and facilitating the promotion and use of related equipment in a wider range of application scenarios and achieving efficient and stable operation.

[0072] Reference Figure 2The diagram illustrates a step flowchart of another embodiment of the water pump flow control method for a cooling fan according to the present invention, which may specifically include the following steps:

[0073] Step 201: Obtain the water level in the water storage tank;

[0074] The first step is to determine the water level in the outlet tank, which is the foundation for the following steps.

[0075] In one example, the water level in the outlet tank can be obtained by a sensor; for example, a hydrostatic water level sensor, an ultrasonic water level sensor, and a capacitive water level sensor. Other types of sensors can also be used to obtain the water level, and this embodiment of the invention does not limit this.

[0076] Step 202: When the water level is higher than the preset water level, determine the current flow rate of the water pump based on the water level, the preset water level, the preset initial flow rate of the water pump, and the preset water pressure resistance coefficient.

[0077] In this step, the water level in the storage tank needs to be monitored continuously or periodically, as this is the fundamental data for flow control. The specific monitoring method can be dynamically set according to different products and business operations, whether it is continuous monitoring or monitoring at a certain time period.

[0078] The preset water level is a pre-defined threshold used to determine when the water pump flow rate needs to be adjusted. When the actual water level exceeds this preset value, the corresponding adjustment logic is executed.

[0079] The preset initial flow rate of the water pump is a preset threshold value used for the initial operating flow rate of the air conditioning water pump.

[0080] The preset water pressure resistance coefficient is an empirically determined coefficient used to adjust the calculation results of the function based on the water level.

[0081] In one embodiment, step 202 includes the following sub-steps:

[0082] Sub-step S11: When the water level is higher than the preset water level, the current flow rate of the water pump is determined according to the following formula based on the water level:

[0083] Q1 = Q0 - (H1 - H) * a, where Q1 is the current flow rate of the water pump, Q0 is the preset initial flow rate of the water pump, H is the preset water level height, a is the preset water pressure resistance coefficient, and H1 is the water level height.

[0084] In one example, 'a' represents the water pressure resistance coefficient; H1 is the water level height detected by the water level sensor; H is the preset water level height, here taken as H = 400; Q1 is the water pump outlet flow rate at the corresponding water level height. The preset initial flow rate of the water pump is taken as Q0 = v0 * S = 800, where v0 is the initial flow velocity of the water pump, taken as 10; S is the cross-sectional area of ​​the corrugated pipe connecting the water pump and the outlet. S is taken as S = 80.

[0085] Step 203: Determine the reference pump flow rate based on the current flow rate of the water pump and the preset standard flow rate;

[0086] The current flow rate is calculated in step 202 and represents the flow rate that the pump should output at the current water level. The preset standard flow rate is the flow rate that the pump should output under ideal or standard conditions, and is the target value for flow control.

[0087] In one embodiment, step 203 includes the following sub-steps:

[0088] Sub-step S21: If the current flow rate of the water pump is less than the preset standard flow rate, determine the reference water pump flow rate based on the current flow rate of the water pump and the preset standard flow rate.

[0089] In one example, when the current flow rate of the water pump is less than the preset standard flow rate, the reference water pump velocity v2 can be calculated according to the following formula: v2=Q1 / S-(Q1-Q) / S, where Q represents the preset standard flow rate, which is 500;

[0090] In one embodiment, the method further includes the following steps:

[0091] If the current flow rate of the water pump is greater than the preset standard flow rate, the initial flow rate of the water pump is obtained;

[0092] The reference pump flow rate is determined based on the initial flow rate of the pump, the current flow rate of the pump, the preset standard flow rate, and the preset flow rate function.

[0093] In one example, when the current flow rate of the water pump is greater than the preset standard flow rate, the reference water pump velocity is determined according to the following formula: v1=v0-(Q1-Q) / S

[0094] Step 204: Control the flow rate of the water pump according to the reference water pump flow rate, so that the flow rate of the water pump is adjusted to the preset standard flow rate.

[0095] The reference pump flow rate is calculated in step 203 and represents the pump flow rate required to achieve the preset standard flow rate. Based on the reference pump flow rate, the actual pump flow rate is changed by adjusting the impeller speed. By controlling the pump flow rate, the system can make the actual output flow rate of the pump gradually approach and eventually reach the preset standard flow rate, thereby achieving precise flow control.

[0096] In one embodiment, step 204 includes the following sub-steps:

[0097] Sub-step S31: If the current flow rate of the water pump is less than the preset standard flow rate, increase the flow rate of the water pump according to the reference water pump flow rate, so that the value of the water pump flow rate is adjusted to the value of the preset flow rate standard.

[0098] If the current flow rate of the water pump is less than the preset standard flow rate, the impeller speed of the water pump needs to be increased. Based on the calculated reference water pump flow rate, the flow rate is increased to further meet the required flow rate.

[0099] In one embodiment, step 204 includes the following sub-steps:

[0100] Sub-step S41: If the current flow rate of the water pump is greater than the preset standard flow rate, reduce the flow rate of the water pump according to the reference water pump flow rate, so that the value of the water pump flow rate is adjusted to the value of the preset flow rate standard.

[0101] If the current flow rate of the water pump is greater than the preset standard flow rate, the impeller speed of the water pump needs to be reduced. Based on the calculated reference water pump flow rate, the flow rate is reduced to reduce unnecessary energy consumption while meeting the required flow rate.

[0102] In one embodiment, the method further includes:

[0103] When the water level in the storage tank is lower than the preset water level, the reference pump flow rate is determined based on the preset standard flow rate and the preset flow rate function.

[0104] In one example, when the water level in the storage tank is lower than the preset water level, the reference water pump flow rate is determined by the following formula: v3 = Q / S

[0105] The flow rate of the water pump is controlled according to the reference water pump flow rate so that the flow rate of the water pump is adjusted to the preset standard flow rate.

[0106] First, by acquiring the water level in the storage tank and determining the current flow rate of the water pump based on the water level, a preset water level, and a preset flow function, the actual flow rate of the water pump at different water levels can be monitored in real time and with precision. This effectively solves the problems of inflexibility and real-time response capability of traditional control methods, allowing the water pump flow rate to be flexibly adjusted according to changes in water level, thereby significantly improving energy utilization efficiency, avoiding energy waste caused by improper flow control, ensuring the stability of equipment operation, and reducing the risk of adverse effects on normal equipment operation due to abnormal flow. Second, by determining the reference water pump flow rate based on the current water pump flow rate, a preset standard flow rate, and a preset flow velocity function, and then controlling the water pump flow rate to adjust the flow rate to the preset standard flow rate, precise control of the water pump flow rate is achieved. This precise control feature helps improve the versatility between different water pump models, eliminating the need for customized designs for different models, greatly reducing the overall production cost, improving the market competitiveness and adaptability of the product, and facilitating the promotion and use of related equipment in a wider range of application scenarios and achieving efficient and stable operation.

[0107] refer to Figure 3 The diagram illustrates the execution logic of an embodiment of a water pump flow control method for a cooling fan according to the present invention.

[0108] First, the humidification function of the air cooler is turned on. Then, the water pump starts working at the initial flow rate V0. At this time, the water level sensor detects the water level H1. Furthermore, the water level changes with time t and the initial flow rate V0 of the water pump. Then, the difference between the current water level H1 and the initial water level H is compared.

[0109] If the water level remains unchanged (H1-H0≤0), the pump maintains its initial flow velocity v0. Then, the cycle returns to the step of detecting the water level height and begins again.

[0110] If the water level rises (H1-H>0), further determine the relationship between flow rate Q1 and Q.

[0111] If Q1 is not greater than Q (Q1-Q≤0), it means that the flow rate has decreased or not increased. At this time, the pump speed is adjusted to v2=Q1 / S-(Q1-Q) / S to cope with the flow rate change, and then the cycle returns to the step of detecting the water level height.

[0112] If Q1 is greater than Q (Q1-Q>0), it indicates that the flow rate has increased. At this time, the pump speed is adjusted to v1=v0-(Q1-Q) / S to slow down the rise in water level. Then, the cycle returns to the step of detecting water level height.

[0113] Reference Figure 4 The diagram shows a structural schematic of a cooling fan product according to an embodiment of a water pump flow control method for a cooling fan of the present invention.

[0114] First, this is a tower air cooler, a device that lowers air temperature through the principle of water evaporation and heat absorption, making it particularly suitable for indoor cooling in summer. The diagram shows the water pump, water outlet, water level, and outlet height H.

[0115] The water pump, located at the bottom of the tower air cooler, is the core of the entire water circulation system. It is responsible for drawing water from the storage container and raising it to the height of the outlet. The performance of the water pump, such as flow rate and head, directly affects the cooling effect and operating efficiency of the air cooler.

[0116] The water level indicates the height of the water in the storage container. The height of the water level affects the operation of the water pump, as the pump needs to draw water from this level.

[0117] The water outlet is located at the top of the evaporator, where the evaporator sprays water. By atomizing or spraying the water, it increases the humidity of the air and absorbs heat as the water evaporates, thus achieving a cooling effect.

[0118] The outlet height H represents the vertical distance from the water pump to the outlet. This height is crucial for determining the head the water pump needs to provide, as the pump must have sufficient power to lift the water to this height for it to dispense water properly.

[0119] During the operation of a tower air cooler, a water pump draws water from a storage container. The water level changes continuously during this process. The pump then raises the water to an outlet height H, and finally, the water is sprayed out through the outlet. Throughout this process, the water level, the pump performance, and the outlet height are all interconnected key factors that collectively determine whether the air cooler can function properly and how effective its cooling is.

[0120] 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.

[0122] Water level acquisition module 301 is used to acquire the water level of the water storage tank;

[0123] The first step is to determine the water level in the outlet tank, which is the foundation for the following steps.

Other types of sensors can also be used to obtain the water level, and this embodiment of the invention does not limit this.

[0125] The current flow acquisition module 302 is used to determine the current flow rate of the water pump based on the water level and the preset water level when the water level is higher than the preset water level.

The specific monitoring method can be dynamically set according to different products and business operations, whether it is continuous monitoring or monitoring at a certain time period.

[0127] The preset water level is a pre-defined threshold used to determine when the water pump flow rate needs to be adjusted. When the actual water level exceeds this preset value, the corresponding adjustment logic is executed.

[0128] The reference flow rate acquisition module 303 is used to determine the reference water pump flow rate based on the current flow rate of the water pump and the preset standard flow rate.

[0129] The current flow rate is calculated in step 302 and represents the flow rate that the pump should output at the current water level. The preset standard flow rate is the flow rate that the pump should output under ideal or standard conditions, and is the target value for flow control.

[0130] The water pump control module 304 is used to control the flow rate of the water pump according to the reference water pump flow rate, so as to adjust the flow rate of the water pump to the preset standard flow rate.

[0131] The reference pump flow rate is calculated in step 303 and represents the pump flow rate required to achieve the preset standard flow rate. Based on the reference pump flow rate, the actual pump flow rate is changed by adjusting the impeller speed. By controlling the pump flow rate, the system can gradually bring the actual pump output flow rate closer to and eventually reach the preset standard flow rate, thereby achieving precise flow control.

[0136] Q1 = Q0 - (H1 - H) * a, where Q1 is the current flow rate of the water pump, Q0 is the preset initial flow rate of the water pump, H is the preset water level height, a is the preset water pressure resistance coefficient, and H1 is the water level height.

[0137] In one example, 'a' represents the water pressure resistance coefficient; H1 is the water level height detected by the water level sensor; H is the preset water level height, here taken as H = 400; Q1 is the water pump outlet flow rate at the corresponding water level height. The preset initial flow rate of the water pump is taken as Q0 = v0 * S = 800, where v0 is the initial flow velocity of the water pump, taken as 10; S is the cross-sectional area of ​​the corrugated pipe connecting the water pump and the outlet. S is taken as S = 80.

[0138] In one embodiment, the reference flow rate acquisition module includes:

[0139] If the current flow rate of the water pump is less than the preset standard flow rate, a reference water pump flow rate is determined based on the current flow rate of the water pump and the preset standard flow rate.

[0140] In one example, when the current flow rate of the water pump is less than the preset standard flow rate, the reference water pump velocity v2 can be calculated according to the following formula: v2=Q1 / S-(Q1-Q) / S, where Q represents the preset standard flow rate, which is 500;

[0141] In one embodiment, the water pump control module includes:

[0142] The flow rate increase submodule is used to increase the flow rate of the water pump according to the reference water pump flow rate when the current flow rate of the water pump is less than the preset standard flow rate, so as to adjust the value of the water pump flow rate to the value of the preset flow rate standard.

[0143] If the current flow rate of the water pump is less than the preset standard flow rate, the impeller speed of the water pump needs to be increased. Based on the calculated reference water pump flow rate, the flow rate is increased to further meet the required flow rate.

[0144] In one embodiment, the device further includes:

[0145] The initial flow rate acquisition submodule is used to acquire the initial flow rate of the water pump when the current flow rate of the water pump is greater than the preset standard flow rate.

[0146] The first reference acquisition submodule is used to determine the reference pump flow rate based on the initial flow rate of the pump, the current flow rate of the pump, the preset standard flow rate, and the preset flow rate function.

[0147] In one example, when the current flow rate of the water pump is greater than the preset standard flow rate, the reference water pump velocity is determined according to the following formula: v1=v0-(Q1-Q) / S

[0148] In one embodiment, the water pump control module includes:

[0149] The flow rate reduction submodule is used to reduce the flow rate of the water pump according to the reference water pump flow rate when the current flow rate of the water pump is greater than the preset standard flow rate, so as to adjust the value of the water pump flow rate to the value of the preset flow rate standard.

[0150] If the current flow rate of the water pump is greater than the preset standard flow rate, the impeller speed of the water pump needs to be reduced. Based on the calculated reference water pump flow rate, the flow rate is reduced to reduce unnecessary energy consumption while meeting the required flow rate.

[0151] In one embodiment, the device further includes:

[0152] The second reference flow rate acquisition submodule is used to determine the reference water pump flow rate based on the preset standard flow rate and the preset flow rate function when the water level in the water storage tank is lower than the preset water level.

[0153] The second flow rate control submodule is used to control the flow rate of the water pump according to the reference water pump flow rate, so as to adjust the flow rate of the water pump to the preset standard flow rate.

[0154] In one example, when the water level in the storage tank is lower than the preset water level, the reference water pump flow rate is determined by the following formula: v3 = Q / S;

[0155] First, by acquiring the water level in the storage tank and determining the current flow rate of the water pump based on the water level, a preset water level, and a preset flow function, the actual flow rate of the water pump at different water levels can be monitored in real time and with precision. This effectively solves the problems of inflexibility and real-time response capability of traditional control methods, allowing the water pump flow rate to be flexibly adjusted according to changes in water level, thereby significantly improving energy utilization efficiency, avoiding energy waste caused by improper flow control, ensuring the stability of equipment operation, and reducing the risk of adverse effects on normal equipment operation due to abnormal flow. Second, by determining the reference water pump flow rate based on the current water pump flow rate, a preset standard flow rate, and a preset flow velocity function, and then controlling the water pump flow rate to adjust the flow rate to the preset standard flow rate, precise control of the water pump flow rate is achieved. This precise control feature helps improve the versatility between different water pump models, eliminating the need for customized designs for different models, greatly reducing the overall production cost, improving the market competitiveness and adaptability of the product, and facilitating the promotion and use of related equipment in a wider range of application scenarios and achieving efficient and stable operation.
