Description

Technical Field

[0001] This application relates to the field of wind turbine technology, and in particular to a control method, device, electronic equipment and storage medium for a side-discharge wind turbine unit. Background Technology

[0002] Based on their air outlet method, fan units can be divided into top-discharge fan units and side-discharge fan units. Side-discharge fan units, due to their unique structure, often face the problem of water blowing. When the unit is in heating mode, condensate is produced in the outdoor unit, flows to the chassis, and then drains out through the drain hole. When the fan rotates, a negative pressure is generated inside the unit, preventing the condensate from draining properly; and with the vibration of the unit, water droplets splash, and under the action of negative pressure, the condensate is eventually blown out. Compared to top-discharge fan units, side-discharge fan units often occupy less space and require less installation space, making them suitable for installation in areas with high foot traffic, such as supermarkets or the areas around buildings. However, the water blowing from the unit can also cause inconvenience to passersby.

[0088] In order to solve the technical problem of how to alleviate or even avoid the occurrence of water blowing by side-discharge fan units in the prior art, this application provides a control method for side-discharge fan units, which can alleviate or even avoid the occurrence of water blowing by side-discharge fan units.

[0089] Figure 1 This is a flowchart illustrating a control method for a side-discharge fan unit provided in an embodiment of this application. This method can be applied to one or more electronic devices such as a control device for a side-discharge fan unit, a smartphone, a laptop, a desktop computer, a portable computer, or a server. Furthermore, the execution entity of this method can be hardware or software. When the execution entity is hardware, it can be one or more of the aforementioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the execution entity is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are imposed here.

[0090] like Figure 1 As shown, the method specifically includes:

[0091] Step 101: Determine the fan type and actual operating information of the side-discharge fan unit.

[0092] In this embodiment, the side-discharge fan unit can be a fan unit that blows air to the side.

[0093] Fan types may include, but are not limited to: single-fan side-discharge fan units, multi-fan side-discharge fan units with a single heating electronic expansion valve (e.g., dual-fan side-discharge fan units with a single heating electronic expansion valve), and multi-fan units with multiple heating electronic expansion valves (e.g., dual-fan units with dual heating electronic expansion valves).

[0094] Actual operating information can refer to the information obtained by the aforementioned side-discharge fan unit during actual operation. For example, actual operating information may include, but is not limited to, at least one of the following: ambient temperature, heating operation duration, and target temperature difference. The heating operation duration represents the time elapsed from the start of heating operation to the current time. The target temperature difference is the difference between the ambient temperature and the low-pressure zone temperature of the side-discharge fan unit.

[0095] In some cases, the aforementioned side-discharge fan units can be installed in air conditioning devices (such as air conditioners), ventilation equipment, or air purification equipment.

[0096] Step 102: Based on the actual operating information, determine whether to implement anti-water blowing control for the side-discharge fan unit.

[0097] In this embodiment, after obtaining the actual operating information, it can be further determined whether to perform anti-water blowing control on the side-discharge fan unit based on the actual operating information.

[0098] In some optional implementations of this embodiment, the following method can be used to determine whether to perform anti-water blowing control on the side-discharge fan unit based on the actual operating information:

[0099] If the actual operating information meets the preset conditions, it is determined that the side-discharge fan unit should be subject to anti-water blowing control; if the actual operating information does not meet the preset conditions, it is determined that the side-discharge fan unit should not be subject to anti-water blowing control.

[0100] The preset conditions include at least one of the following:

[0101] The first point is that the ambient temperature indicated by the actual operating information falls within the preset temperature range.

[0102] As an example, the preset temperature range can be 0 to 10 degrees Celsius.

[0103] The second item is that the heating runtime indicated by the actual operating information is longer than the preset runtime.

[0104] The heating operation duration refers to the time between the start of the heating operation and the current time.

[0105] As an example, the preset duration could be 30 minutes, 1 hour, etc.

[0106] Thirdly, the target temperature difference indicated by the actual operating information is greater than the preset temperature difference.

[0107] The target temperature difference is the difference between the ambient temperature and the low-pressure zone temperature of the side-discharge fan unit.

[0108] As an example, the preset temperature difference can be 10 degrees Celsius.

[0109] Specifically, if the ambient temperature indicated by the actual operating information is within the preset temperature range, then it can be determined that the side-discharge fan unit is subject to anti-water blowing control; if the ambient temperature indicated by the actual operating information is not within the preset temperature range, then it can be determined that the side-discharge fan unit is not subject to anti-water blowing control.

[0110] If the ambient temperature indicated by the actual operating information is within the preset temperature range, and the heating operation time indicated by the actual operating information is greater than the preset duration, then it can be determined that the side-discharge fan unit will be subject to anti-water blowing control; if the ambient temperature indicated by the actual operating information is not within the preset temperature range, or the heating operation time indicated by the actual operating information is not greater than the preset duration, then it can be determined that the side-discharge fan unit will not be subject to anti-water blowing control.

[0111] If, under the preset conditions including the first, second, and third conditions mentioned above, the ambient temperature indicated by the actual operating information is within the preset temperature range, the heating operation time indicated by the actual operating information is greater than the preset duration, and the target temperature difference indicated by the actual operating information is greater than the preset temperature difference, then it can be determined that anti-water blowing control will be applied to the side-discharge fan unit. If the ambient temperature indicated by the actual operating information is not within the preset temperature range, or the heating operation time indicated by the actual operating information is not greater than the preset duration, or the target temperature difference indicated by the actual operating information is not greater than the preset temperature difference, then it can be determined that anti-water blowing control will not be applied to the side-discharge fan unit.

[0112] It is understood that, in the above optional implementation methods, if the actual operating information meets at least one of the above conditions, the side-discharge fan unit usually has a water blowing problem. In this case, the side-discharge fan unit can be controlled to prevent water blowing, so that the operating frequency of the side-discharge fan unit can alleviate or even avoid the occurrence of water blowing by the side-discharge fan unit.

[0113] Step 103: If it is determined that the side-discharge fan unit is subject to anti-water blowing control, the water blowing control frequency of the side-discharge fan unit is determined based on the fan type, wherein the water blowing control frequency is the frequency used to control the water blowing of the side-discharge fan unit.

[0114] In this embodiment, when it is determined that the side-discharge fan unit is subject to anti-blowing control, a blow-blowing control frequency that matches the fan type of the side-discharge fan unit can be determined based on the fan type.

[0115] The water blowing control frequency can be used to control the frequency of water blowing by the side-discharge fan unit.

[0116] In practice, the lower the operating frequency of the fan in the side-discharge fan unit, the more likely the water blowing phenomenon can be avoided.

[0117] Here, the water blowing control frequency of the side-discharge fan unit can be determined in various ways based on the fan type.

[0118] In some optional implementations of this embodiment, the water blowing control frequency of the side-discharge fan unit can be determined based on the fan type in the following manner:

[0119] When the fan type indicates that the side-discharge fan unit is a single-fan unit (i.e., the aforementioned single-fan side-discharge fan unit), the water blowing control frequency of the side-discharge fan unit is determined to be less than or equal to the second preset frequency.

[0120] As an example, the second preset frequency could be 50 Hz, 60 Hz, etc.

[0121] It is understandable that, in the above-mentioned optional implementation methods, for single-fan side-discharge fan units, their operating frequency (i.e., water blowing control frequency) can be limited to not exceeding the second preset frequency. This can alleviate or even prevent water blowing by single-fan side-discharge fan units.

[0122] Step 104: Control the side-discharge fan unit to operate according to the water blowing control frequency.

[0123] In this embodiment, after determining the water blowing control frequency, the water blowing control frequency can be used as the operating frequency of the side-discharge fan unit, thereby controlling the side-discharge fan unit to operate according to the water blowing control frequency.

[0124] The control method for the side-discharge fan unit provided in this application embodiment can determine the fan type and actual operating information of the side-discharge fan unit. Then, based on the actual operating information, it is determined whether to implement anti-water blowing control for the side-discharge fan unit. If anti-water blowing control is determined, the water blowing control frequency of the side-discharge fan unit is determined based on the fan type, wherein the water blowing control frequency is the frequency used to control the side-discharge fan unit to blow water. Finally, the side-discharge fan unit is controlled to operate according to the water blowing control frequency. Therefore, the actual operating information of the side-discharge fan unit can be used to determine whether anti-water blowing control is needed. If anti-water blowing control is needed, the water blowing control frequency is determined based on the fan type of the side-discharge fan unit, and its operation is controlled according to this water blowing control frequency. This ensures that the operating frequency for controlling the side-discharge fan unit to blow water matches the fan type, thereby mitigating or even preventing water blowing from the side-discharge fan unit.

[0125] Figure 2 This is a flowchart illustrating another control method for a side-discharge fan unit provided in an embodiment of this application. Figure 2 As shown, the method specifically includes:

[0126] Step 201: Determine the fan type and actual operating information of the side-discharge fan unit.

[0127] In this embodiment, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same, and will not be repeated here.

[0128] Step 202: Based on the actual operating information, determine whether to implement anti-water blowing control for the side-discharge fan unit.

[0129] In this embodiment, step 202 and Figure 1 Step 102 in the corresponding embodiment is basically the same, and will not be repeated here.

[0130] Step 203: If it is determined that the side-discharge fan unit is subject to anti-blowing control, and the fan type indicates that the side-discharge fan unit is a dual-fan unit, determine the number of heating electronic expansion valves in the side-discharge fan unit.

[0131] In this embodiment, the dual-fan unit is also known as the aforementioned dual-fan side-discharge fan unit.

[0132] The heating electronic expansion valve can be used to control the flow of refrigerant.

[0133] Step 204: Based on the quantity, determine the water blowing control frequency of the side-discharge fan unit, wherein the water blowing control frequency is the frequency used to control the water blowing of the side-discharge fan unit.

[0134] In this embodiment, different water blowing control frequencies can be determined for different numbers of heating electronic expansion valves.

[0135] As for how to determine the water blowing control frequency of the side-discharge fan unit based on the quantity, please refer to the following description, which will not be elaborated here.

[0136] Step 205: Control the side-discharge fan unit to operate according to the water blowing control frequency.

[0137] In this embodiment, step 205 and Figure 1 Step 104 in the corresponding embodiment is basically the same, and will not be repeated here.

[0138] In some optional implementations of this embodiment, when the quantity is one, the water blowing control frequency of the side-discharge fan unit can be determined based on the quantity in the following manner:

[0139] The first step is to determine whether the water blowing control frequency of the lower fan of the side-discharge fan unit is less than or equal to the first preset frequency.

[0140] As an example, the first preset frequency could be 45 Hz, 50 Hz, etc.

[0141] The second step is to determine a target increase in the water blowing control frequency of the upper fan of the side-discharge fan unit if the target operating frequency of the lower fan is greater than the first preset frequency. The target value is the difference between the target operating frequency and the first preset frequency.

[0142] The target operating frequency can be the desired operating frequency of the down fan of the side-discharge fan unit.

[0143] In some cases, the operating frequency of the upwind fan does not exceed its maximum operating frequency.

[0144] It is understandable that after a single-heating electronic expansion valve unit enters anti-blowing control mode, it can limit the frequency of the down fan to not exceed a first preset frequency. If the target operating frequency of the down fan is greater than the first preset frequency, the frequency of the up fan is controlled to increase by the target value. In this way, it can both alleviate or even avoid the occurrence of water blowing by the single-heating electronic expansion valve unit and ensure that the operating frequency of the single-heating electronic expansion valve unit meets the requirements as much as possible.

[0145] In some optional implementations of this embodiment, the side-discharge fan unit is used for temperature regulation.

[0146] Based on this, when the quantity is two, the water blowing control frequency of the side-discharge fan unit can be determined according to the quantity as follows:

[0147] The first step is to determine the target energy value for the side-discharge fan unit.

[0148] The target energy value represents the energy required to adjust the ambient temperature to the target temperature.

[0149] The target energy value represents the energy required to be provided by the side-discharge fan unit. Factors affecting this target energy value may include, but are not limited to, at least one of the following: ambient temperature, set temperature (target temperature), number of fans in operation, and fan speed setting.

[0150] As an example, the target energy value 'a' can be determined using the following formula: a = a1 + a2.

[0151] Where, a1 = N1 × T;

[0152] N1 represents the preset first coefficient, T represents the difference between the fan's set temperature and the ambient temperature. N2 represents the preset second coefficient. tn is the duration of each of the M equal parts of a time period. n represents the identifier of the m durations.

[0153] The second step is to determine the water blowing control frequency of the side-discharge fan unit based on the target energy value.

[0154] Here, the water blowing control frequency corresponding to the target energy value can be determined through a pre-defined correspondence table, thereby obtaining the water blowing control frequency of the side-discharge fan unit.

[0155] In addition, other methods can be used to achieve the second step mentioned above, which will not be elaborated here.

[0156] In some cases, the blowing control frequency can be positively correlated with the target energy value.

[0157] It is understood that, in the above-mentioned optional implementation methods, the water blowing control frequency of the side-discharge fan unit can be determined by the target energy value of the side-discharge fan unit. In this way, different water blowing control frequencies can be determined for different target energy values, thereby mitigating or even avoiding the occurrence of water blowing by the side-discharge fan unit to a greater extent, and ensuring that the operating frequency of the dual-heating electronic expansion valve unit meets the requirements as much as possible.

[0158] In some application scenarios of the above-mentioned optional implementation methods, the water blowing control frequency of the side-discharge fan unit can be determined based on the target energy value in the following manner:

[0159] If the target energy value is less than or equal to the first energy value, the water blowing control frequency of the upper fan of the side-discharge fan unit is determined to be the current operating frequency of the upper fan, and the water blowing control frequency of the lower fan of the side-discharge fan unit is determined to be 0 (i.e., the lower fan is turned off).

[0160] When the target energy value is greater than the first energy value and less than or equal to the second energy value, the water blowing control frequency of the upper fan of the side-discharge fan unit is determined to be the upper limit operating frequency (i.e., the maximum operating frequency) of the upper fan, and the water blowing control frequency of the lower fan of the side-discharge fan unit is determined to be the current operating frequency of the lower fan.

[0161] When the target energy value is greater than the second energy value, the water blowing control frequency of the upper fan of the side-discharge fan unit is determined to be the upper limit operating frequency (i.e., the maximum operating frequency) of the upper fan, and the water blowing control frequency of the lower fan of the side-discharge fan unit is determined to be the upper limit operating frequency (i.e., the maximum operating frequency) of the lower fan.

[0162] The first energy value is less than the second energy value.

[0163] Please refer to Figure 3A and Figure 3B . Figure 3A This is a schematic diagram of the structure of a multi-heating electronic expansion valve multi-fan side-discharge fan unit, which is a control method for a side-discharge fan unit provided in an embodiment of this application. Figure 3B This is a schematic diagram of the structure of a single-heating electronic expansion valve multi-fan side-discharge fan unit, which is part of a control method for a side-discharge fan unit provided in an embodiment of this application.

[0164] When the target energy value 'a' of the entire system is less than or equal to the first energy value, the system capacity requirement is relatively small, and only the upper fan needs to be turned on to meet it. In this case, the upper fan is on, and the lower fan is off. Furthermore, the upper heat exchanger can be used, while the lower heat exchanger is not used. Correspondingly, heating electronic expansion valve 1 is open, and heating electronic expansion valve 2 is closed. When the upper fan is on, it will not generate water blowing. An initial frequency, such as 20 Hz, can be given when the upper fan is first turned on. Afterward, the operating frequency can be adjusted according to the frequency adjustment strategy, for example, it can operate at 30 Hz.

[0165] When the first energy value A1 of the entire system is less than the target energy value a and less than the second energy value A2, if the current capacity requirement is not met even if the upper fan is turned on to its maximum frequency (i.e., the upper limit operating frequency mentioned above), the lower fan and the lower heat exchanger will be activated simultaneously, but the frequency of the lower fan is limited to not exceeding the upper limit operating frequency of the lower fan. At this time, the corresponding heating electronic expansion valves 1 and 2 are fully opened.

[0166] When the target energy value a of the entire system is greater than the second energy value A2, the system demand is relatively large. Therefore, all upper and lower fans and heat exchangers are activated, and the fans operate at their maximum frequency (i.e., the aforementioned upper limit operating frequency). Correspondingly, all heating electronic expansion valves are opened.

[0167] It is understandable that in the above application scenarios, different methods can be used to determine the water blowing control frequency when the target energy value belongs to different energy levels. In this way, the occurrence of water blowing by the side-discharge fan unit can be alleviated or even avoided to a greater extent, and the operating frequency of the dual-heating electronic expansion valve unit can be made to meet the requirements as much as possible.

[0168] It should be noted that, in addition to the contents described above, this embodiment may also include... Figure 1 The corresponding technical features described in the corresponding embodiments, thereby achieving Figure 1 For details on the technical effects of the control method for the side-discharge fan unit shown, please refer to [link / reference needed]. Figure 1 The relevant descriptions are presented concisely and will not be elaborated upon here.

[0169] The control method for the side-discharge fan unit provided in this application embodiment can determine its water blowing control frequency based on the number of heating electronic expansion valves in the dual-fan side-discharge fan unit. This can alleviate or even avoid the occurrence of water blowing in the dual-fan side-discharge fan unit.

[0170] The embodiments of this application are described below by way of example. However, it should be noted that the embodiments of this application may have the features described below, but the following description does not constitute a limitation on the protection scope of the embodiments of this application.

[0171] Air conditioning units can be categorized into top-discharge and side-discharge units based on their air outlet method. Side-discharge units, due to their unique structure, often face the problem of water discharge: during heating operation, condensate is produced in the outdoor unit, flows to the chassis, and drains out through the drain hole. When the fan rotates, a negative pressure is created inside the unit, preventing the condensate from draining properly; furthermore, the unit's vibration causes water droplets to splash, and under the influence of this negative pressure, the condensate is eventually blown out.

[0172] Compared to top-discharge fan units, side-discharge fan units typically occupy less space and require less installation room, making them suitable for installation in high-traffic areas such as supermarkets and backyards. However, the water blowing from these units can also cause inconvenience to passersby.

[0173] Regarding the issue of water blowing in the heating mode of side-discharge fan units, this method can determine whether to enter the anti-water blowing control based on the ambient temperature (i.e., room temperature), low-pressure zone parameters (e.g., pressure, temperature), and continuous heating operation time (i.e., the aforementioned heating operation duration).

[0174] The low-pressure zone parameter refers to real-time data. During operation, the unit exists in both high-pressure and low-pressure zones, referred to as high pressure and low pressure in the refrigeration industry, respectively. Low pressure refers to the real-time pressure or temperature data within the system. Continuous heating operation time refers to the duration from the start of this heating cycle to the current moment.

[0175] After the unit enters anti-blowing control:

[0176] ① For single-fan side-discharge fan units, the operating frequency of the fan is limited, that is, the water blowing control frequency of the side-discharge fan unit is less than or equal to the second preset frequency.

[0177] ② For multi-fan side-discharge fan units with a single heating electronic expansion valve (e.g., dual-fan side-discharge fan units with a single heating electronic expansion valve), the operating frequency of the down fan is limited, that is, the water blowing control frequency of the down fan is less than or equal to the first preset frequency; the operating frequency of the up fan is increased, that is, the water blowing control frequency of the up fan is increased by the target value.

[0178] ③ Multi-fan units with multiple heating electronic expansion valves (e.g., dual-fan units with multiple heating electronic expansion valves) selectively activate the lower fan and lower heat exchanger based on changes in system capacity requirements (i.e., the aforementioned target energy value), and limit the operating frequency of the lower fan. For multi-fan units with multiple heating electronic expansion valves, such as dual-fan units with dual heating electronic expansion valves, the heating electronic expansion valve and the fan have a one-to-one relationship. However, other situations are not excluded; currently, dual-fan units with dual heating electronic expansion valves are commonly used. The heating electronic expansion valve cannot control the fan; it is used in conjunction with the fan, for example... Figure 3B When the upper heat exchanger is in use, the heating electronic expansion valve 1 and the upper fan are used simultaneously.

[0179] Side-discharge fan units can be categorized by the number of fans: single-fan side-discharge fan units and multi-fan side-discharge fan units. Multi-fan side-discharge fan units can be further classified based on the number of heating valves, such as single-heating electronic expansion valve side-discharge fan units (see [link]). Figure 3B ), multi-heating electronic expansion valve side-discharge air handling unit (see Figure 3A ).

[0180] In heating mode, the unit (i.e., the aforementioned side-discharge fan unit) enters anti-blowing control when the following conditions are met simultaneously:

[0181] ① The current ambient temperature is within the preset temperature range, that is, the ambient temperature is within the preset temperature range.

[0182] The preset temperature range is a custom temperature value, such as an ambient temperature of 0 to 10°C (this is just an example).

[0183] ② The heating operation time (i.e., the heating operation duration) is greater than the preset value t minutes (i.e., the preset duration mentioned above).

[0184] Where t minutes can be 30 minutes, 1 hour, etc. (for example only).

[0185] ③ The difference between the ambient temperature and the temperature of the low-pressure area (i.e., the target temperature difference mentioned above) is greater than the preset value X (i.e., the preset temperature difference mentioned above).

[0186] The preset value X can be, for example, 10 (this is just an example).

[0187] 1. For single-fan side-discharge fan units:

[0188] After entering the anti-blowing control, the fan frequency is limited to not exceeding the preset value f1Hz (that is, the second preset frequency mentioned above).

[0189] The default value f1 can be, for example, 50Hz (this is just an example).

[0190] 2. For dual-fan side-discharge fan units:

[0191] ① After the single-heating electronic expansion valve unit enters the anti-blowing control, the frequency of the down fan is limited to not exceeding the preset value f2 Hz (that is, the first preset frequency mentioned above). If the target control frequency f3 (that is, the target operating frequency mentioned above) of the down fan is greater than f2, then the frequency of the up fan is increased by f3-f2 Hz. However, the operating frequency of the up fan shall not exceed its maximum operating frequency.

[0192] The preset value f2 can be, for example, 45Hz.

[0193] ② Dual-heating electronic expansion valve unit:

[0194] After entering the anti-blowing control, based on the capacity requirement value 'a' of the entire system (i.e., the target energy value mentioned above), determine whether the down fan should be turned on and its operating frequency; determine whether the down heat exchanger should be used.

[0195] There are many factors that affect capacity requirements, such as ambient temperature, set temperature, number of fans in operation, and fan speed settings.

[0196] For details on how to calculate energy demand, please refer to the above description; it will not be repeated here.

[0197] Here, when the maximum frequency of the downdraft fan is F1max, the unit does not blow water. F1 is the default value, determined during the in-house matching test of the model.

[0198] Specifically, the control methods for fans and heat exchangers for different capacity requirements can be referred to in the table below:

[0199]

[0200] When the overall system capacity requirement 'a' (i.e., the target energy value mentioned above) is less than or equal to the preset value A1 (i.e., the first energy value mentioned above), the system capacity requirement is relatively small and can be met by simply operating the upper fan. In this case, the upper fan is on, and the lower fan is off; the upper heat exchanger is activated, and the lower heat exchanger is not used. Correspondingly, heating electronic expansion valve 1 is open, and heating electronic expansion valve 2 is closed. No water blowing occurs when the upper fan is running, therefore the fan frequency is only affected by the maximum frequency. An initial value, such as 20, is given upon startup, and the operating frequency is adjusted according to the frequency adjustment strategy. Subsequently, it operates automatically based on the system's high pressure.

[0201] When the system's overall capacity requirement preset value A1 (i.e., the first energy value mentioned above) < a (i.e., the target energy value mentioned above) ≤ preset value A2 (i.e., the second energy value mentioned above), and operating the upper fan at its maximum frequency alone is still insufficient to meet the current capacity requirement, the lower fan and lower heat exchanger will be activated simultaneously. However, the lower fan frequency f4 is limited to not exceeding the preset value F1max (i.e., the upper limit operating frequency mentioned above). At this time, the corresponding heating electronic expansion valves 1 and 2 will be fully opened.

[0202] When the overall system capacity requirement a (i.e., the target energy value mentioned above) > the preset value A2 (i.e., the second energy value mentioned above), the system demand capacity is relatively large. In this case, all upper and lower fans and heat exchangers are activated, and all fans operate at their maximum frequency (the lower fan operates at F1max). The corresponding heating electronic expansion valves are all opened.

[0228] If the actual operating information meets the preset conditions, it is determined that the side-discharge fan unit should be subject to anti-water blowing control.

[0229] If the actual operating information does not meet the preset conditions, it is determined that the side-discharge fan unit will not be subject to anti-water blowing control.
