[0002] Air source heat pump systems are typically used for district heating. An air source heat pump system consists of multiple heat pump units, often arranged in an array outdoors. When the air source heat pump system operates in heating mode, the low-temperature air discharged after heat exchange by the heat pump units flows back to the center of the array, causing the air temperature in the center of the array to be significantly lower than the ambient air temperature, thus creating a cold island effect within the array. The presence of the cold island effect significantly reduces the operating efficiency of the air source heat pump system in heating mode and increases its energy consumption. Summary of the Invention

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0022] refer to Figure 1 , Figure 1 This is a flowchart illustrating a control method for an air source heat pump system provided in an embodiment of this application. The control method for an air source heat pump system provided in this application includes the following steps: S101: When the air source heat pump system is running in heating mode, obtain the ambient wind information of the outdoor environment where the air source heat pump system is located.
[0023] In this embodiment, the air source heat pump system is an array-type air source heat pump system. An array-type heat pump system can be understood as an air source heat pump system comprising multiple heat pump units arranged in an array. Ambient wind information includes the actual wind speed and actual wind direction. Specifically, a wind direction sensor can be installed in the air source heat pump system to collect the actual wind direction when the air source heat pump system is operating in heating mode; a wind speed sensor can also be installed in the air source heat pump system to collect the actual wind direction when the air source heat pump system is operating in heating mode. When an air source heat pump system is operating in heating mode, the ambient wind in the outdoor environment will have a certain impact on each heat pump unit in the array-type air source heat pump system. The impact of the ambient wind on each heat pump unit is different, which will have different effects on the cold island effect generated by the array-type air source heat pump system. If the impact of the ambient wind in the outdoor environment is not considered when controlling the heat pump units in the air source heat pump system operating in heating mode, it may further aggravate the cold island effect generated by the air source heat pump system, and fail to improve the cold island effect generated by the air source heat pump system, thereby affecting the operating efficiency of the air source heat pump system and reducing the operating energy consumption of the air source heat pump system.
[0024] S102: Based on the ambient wind information, determine the first ranking result among all heat pump units in the air source heat pump system. The first ranking result is used to characterize the ranking relationship between the degree of influence of all heat pump units in the air source heat pump system on the cold island effect generated by the air source heat pump system.
[0025] In this embodiment, based on the acquired environmental wind information, a first ranking result is determined among all heat pump units in the air source heat pump system according to the influence of the outdoor wind on the air source heat pump system. After obtaining the first ranking result, when controlling the heat pump units in the air source heat pump system, the control can be based on the first ranking result to improve the cooling island effect generated by the air source heat pump system.
[0026] S103: Determine the target load information corresponding to the air source heat pump system.
[0027] In this embodiment, the target load information may include the return water temperature and the supply-return water temperature difference. The supply-return water temperature difference is equal to the difference between the supply water temperature and the return water temperature. Specifically, a temperature sensor can be installed in the return water pipeline of the air source heat pump system to collect the return water temperature; a temperature sensor can also be installed in the supply water pipeline of the air source heat pump system to collect the supply water temperature.
[0028] S104: Control each heat pump system in the air source heat pump system according to the first sorting result and the target load information.
[0029] In this embodiment, upon obtaining the target load information, it can be determined whether the heating demand is met. If the heating demand is not met, a corresponding number of heat pump units in the air source heat pump system can be controlled according to the first sorting result to ensure that the heating demand is met after the heat pump units are controlled. If the heating demand is met, the corresponding number of heat pump units that meet the heating demand are controlled. It should be noted that when controlling the air source heat pump system, a preset monitoring period can be set. When the preset monitoring period is reached, steps S101 to S104 described above can be executed. The preset monitoring period can be set according to actual needs, and the specific value of the preset monitoring period is not limited in this embodiment. The first sorting result may include a sorting sequence that ranks all heat pump units in the air source heat pump system according to the degree of influence of the heat pump units on the cold island effect of the air source heat pump system from smallest to largest. Of course, the first sorting result may also include an arrangement sequence that sorts all heat pump units in the air source heat pump system according to the degree of influence of the heat pump units on the cold island effect of the air source heat pump system from largest to smallest. In this embodiment, the sorting sequence that sorts all heat pump units in the air source heat pump system according to the degree of influence of the heat pump units on the cold island effect of the air source heat pump system from smallest to largest is selected as the first sorting result. If, based on the target load information, it is determined that the heating demand is not met and a first target number of heat pump units need to be turned on, the first target number of heat pump units with a small degree of influence on the cold island effect of the air source heat pump system can be selected according to the first sorting result and controlled to be turned on. If, based on the target load information, it is determined that the heating demand is not met and a second target number of heat pump units need to be turned off, the first sorting result can be reversed to obtain a second sorting result. According to the second sorting result, the second target number of heat pump units with a large degree of influence on the cold island effect of the air source heat pump system can be selected and controlled to be turned off.
[0030] In the above context, "not meeting heating requirements" can be understood as the return water temperature not meeting the preset temperature or the supply and return water temperature difference not meeting the preset temperature difference; "meeting heating requirements" can be understood as the return water temperature meeting the preset temperature or the supply and return water temperature difference meeting the preset temperature difference.
[0031] This embodiment provides a control method for an air source heat pump system. When controlling the heat pump units in an air source heat pump system operating in heating mode, the method considers the influence of the ambient wind in the outdoor environment on each heat pump unit, which in turn affects the cold island effect generated by the air source heat pump system. By monitoring the ambient wind information of the outdoor environment where the air source heat pump system is located, the method obtains a ranking result of the degree of influence of all heat pump units in the entire air source heat pump system on the cold island effect based on the monitored ambient wind information. Then, based on the ranking result and the determined target load information corresponding to the air source heat pump system, the method controls the heat pump units in the air source heat pump system to improve the cold island effect generated by the array-type air source heat pump, thereby improving the operating efficiency of the air source heat pump system and reducing the operating energy consumption of the air source heat pump system.
[0032] refer to Figure 2 , Figure 2 This is a flowchart illustrating another control method for an air source heat pump system provided in this application embodiment. The control method for an air source heat pump system provided in this application embodiment includes the following steps: S201: When the air source heat pump system is running in heating mode, obtain the ambient wind information of the outdoor environment where the air source heat pump system is located. The ambient wind information includes the actual wind speed and the actual wind direction of the ambient wind.
[0033] In this embodiment, step S201 is the same as step S101 described above. For details, please refer to step S101 described above. In this embodiment, it will not be repeated here.
[0034] S202: Determine whether the actual wind speed is less than or equal to the first preset wind speed.
[0035] S203: When the actual wind speed is less than or equal to the first preset wind speed, obtain the first actual temperature of the heat exchange module in each heat pump unit.
[0036] S204: Determine the first sorting result among all heat pump units in the air source heat pump system based on the actual wind direction and the first actual temperature of the heat exchange module in each of the heat pump units.
[0037] Regarding steps S202 to S204 above, the first preset wind speed can be set according to actual needs, and this embodiment does not impose a specific limitation on it. For example, the first preset wind speed can be 5 m / s. When the actual wind speed is less than or equal to the first preset wind speed, it indicates that in addition to the ambient wind in the outdoor environment where the air source heat pump system is located having a certain impact on the heat pump unit, the temperature of the heat exchange module in the heat pump unit will also have a certain impact on the heat pump unit. Under the influence of the ambient wind and the temperature of the heat exchange module, the heat pump unit will directly affect the cold island effect generated by the air source heat pump system. At this time, when the actual wind speed is less than or equal to the first preset wind speed, in order to obtain the first sorting sequence more accurately and to better improve the cold island effect generated by the air source heat pump system, it is necessary to consider the influence of the ambient wind and the temperature of the heat exchange module in the heat pump unit at the same time, and determine the first sorting result among all heat pump units in the air source heat pump system based on the wind direction of the ambient wind and the temperature of the heat exchange module in the heat pump unit. In the above, a temperature sensor is installed near the heat exchange module in each heat pump unit to collect the temperature of the heat exchange module.
[0038] In step S204, based on the actual wind direction and the first actual temperature of the heat exchange modules in each heat pump unit, the first ranking result among all heat pump units in the air source heat pump system is determined, including: Each heat pump unit in the air source heat pump system is numbered according to the actual wind direction to obtain the first number of each heat pump unit. The heat pump units in the air source heat pump system are numbered in descending order of the first actual temperature of the heat exchange modules in the heat pump unit to obtain the second number of each heat pump unit. For each heat pump unit in the air source heat pump system, the third number of the heat pump unit is determined based on the first number and the second number of the heat pump unit. All heat pump units in the air source heat pump system are sorted in ascending order of their third number to obtain the first sorting result among all heat pump units in the air source heat pump system.
[0039] In the above, when determining the third number of a heat pump unit, it can be obtained by adding the first and second numbers of the same heat pump unit. Numbering each heat pump unit according to the actual wind direction can be understood as referring to... Figure 5 and Figure 6When the actual wind direction is X, the heat pump units in the air source heat pump system are numbered according to the X wind direction (i.e., from the windward direction to the leeward direction). All heat pump units in the Y direction, perpendicular to the X wind direction, have the same number, and the numbers increase sequentially along the X direction until all heat pump units in the air source heat pump system are numbered. For example, if the air source heat pump system includes heat pump unit A, heat pump unit B, and heat pump unit C along the X direction, then the first number x for heat pump unit A can be 1, the first number x for heat pump unit B can be 2, and the first number x for heat pump unit C can be 3. Numbering the heat pump units in the air source heat pump system according to the first actual temperature of the heat exchange modules in descending order can be understood as the second number of all heat pump units in the air source heat pump system increasing sequentially according to the first actual temperature of the heat exchange modules in descending order. For example, an air source heat pump system includes heat pump unit A, heat pump unit B, and heat pump unit C. The first actual temperature of the heat exchange module in heat pump unit A is higher than that of the heat exchange module in heat pump unit B, and the first actual temperature of the heat exchange module in heat pump unit B is higher than that of the heat exchange module in heat pump unit C. Therefore, the second number y of heat pump unit A can be 1, the second number y of heat pump unit B can be 2, and the number y of heat pump unit C can be 3. After obtaining the first and second numbers of each heat pump unit in the air source heat pump system, the third number z is obtained by adding the first and second numbers of each heat pump unit. For example, given that the first number x of heat pump unit A can be 1, the first number x of heat pump unit B can be 2, and the first number x of heat pump unit C can be 3, and that the second number y of heat pump unit A can be 1, the second number y of heat pump unit B can be 2, and the number y of heat pump unit C can be 3, we can obtain the third number z of heat pump unit A as 2, the third number z of heat pump unit B as 3, and the third number z of heat pump unit C as 6. After obtaining the third numbers of each heat pump unit in the air source heat pump system, all heat pump units are sorted in ascending order of their third numbers to obtain the first sorting sequence. For example, based on the fact that the third number z of heat pump unit A is 2, the third number z of heat pump unit B is 3, and the third number z of heat pump unit C is 6, sorting heat pump unit A, heat pump unit B, and heat pump unit C can yield a first sorting result that includes the sorting sequence of heat pump unit A, heat pump unit B to heat pump unit C.
[0040] S205: When the actual wind speed is greater than the first preset wind speed, determine the target comparison result between the actual wind direction and the preset wind direction.
[0041] S206: Based on the target comparison results, determine the first ranking result among all heat pump units in the air source heat pump system.
[0042] Regarding steps S205 and S206 above, the preset airflow direction corresponds to the heat exchange section in the heat pump unit (i.e., the preset airflow direction faces different heat exchange sections in the heat pump unit). The heat exchange section in the heat pump unit is used to characterize the size of the heat exchange area. The preset airflow direction includes a first preset airflow direction and a second preset airflow direction. The heat pump unit includes a first heat exchange section and a second heat exchange section. The heat exchange area corresponding to the first heat exchange section is smaller than the heat exchange area of the second heat exchange section. The first preset airflow direction faces the first heat exchange section, and the second preset airflow direction faces the second heat exchange section. When the actual wind speed is greater than the first preset wind speed, although the ambient wind can carry away some cooling energy, the different heat exchange sections in the heat pump unit corresponding to different airflow directions will still have a certain impact on the cold island effect generated by the entire air source heat pump system. Therefore, when determining the first ranking result, the target comparison result between the actual airflow direction and the preset airflow direction is taken into account to obtain a more accurate first ranking result. This allows for better improvement of the cold island effect generated by the air source heat pump system when using the first ranking result to control the heat pump unit. refer to Figure 5 and Figure 6 As shown, the first preset wind direction can be the Y-direction, and the second preset wind direction can be the X-direction. A first heat exchange section is installed on the heat pump unit in the Y-direction direction; a second heat exchange section is installed on the heat pump unit in the X-direction direction. It should be noted that when the actual wind direction collected by the wind direction sensor is closer to the X-direction, the actual wind direction is determined to be the X-direction; when the actual wind direction collected by the wind direction sensor is closer to the Y-direction, the actual wind direction is determined to be the Y-direction.
[0043] Specifically, when the actual wind speed exceeds the first preset wind speed, the heat pump unit has different heat exchange areas in different directions. Therefore, different wind directions will have different effects on the heat pump unit, thus affecting the cold island effect generated by the air source heat pump system. Thus, when the actual wind speed exceeds the first preset wind speed, the impact of the actual wind direction on the heat pump unit must be considered. Specifically, based on the target comparison results, the first ranking result among all heat pump units in the air source heat pump system is determined, including: When the target comparison results include the actual wind direction being the first preset wind direction, the first actual temperature of the heat exchange module in each heat pump unit is obtained. Based on the actual wind direction and the first actual temperature of the heat exchange modules in each heat pump unit, the first ranking result among all heat pump units in the air source heat pump system is determined.
[0044] In the above, when the actual wind direction is the first preset wind direction, since the first preset wind direction is towards the heat exchange section with a smaller heat exchange area in the heat pump unit, when determining the first ranking result, it is necessary to consider not only the influence of the actual ambient wind direction on the heat pump unit, but also the influence of the temperature of the heat exchange module in the heat pump unit on the heat pump unit, in order to obtain the first ranking result more accurately. When using the first ranking result to control the heat pump unit, it can better improve the cold island effect generated by the air source heat pump system. The determination of the first ranking result by obtaining the first actual temperature of the heat exchange module in each heat pump unit is consistent with the above, and will not be repeated here in this embodiment.
[0045] More specifically, determining the first ranking among all heat pump units in an air source heat pump system based on the target comparison results also includes: When the target comparison result includes the actual wind direction being the second preset wind direction, all heat pump units in the air source heat pump system are sorted according to the actual wind direction to obtain the first sorting result among all heat pump units in the air source heat pump system.
[0046] In the above, when the actual wind direction is the second preset wind direction, since the second preset wind direction is towards the heat exchange section with a larger heat exchange area in the heat pump unit, when determining the first ranking result, only the influence of the actual ambient wind direction on the heat pump unit needs to be considered to obtain a more accurate first ranking result. When using the first ranking result to control the heat pump unit, the cold island effect generated by the air source heat pump system can be better improved. Ranking all heat pump units in the air source heat pump system according to the actual wind direction can be understood as, when the actual wind direction is X, referring to... Figure 4 and Figure 5 That is, all heat pump units in the air source heat pump system are numbered and sorted sequentially according to the direction indicated by the X wind direction arrow in the figure (i.e., from the windward direction to the leeward direction).
[0047] S207: Determine the target load information corresponding to the air source heat pump system.
[0048] In this embodiment, step S207 is the same as step S103 described above. For details, please refer to step S103 described above. In this embodiment, it will not be repeated here.
[0049] S208: Control each heat pump unit in the air source heat pump system according to the first sorting result and target load information.
[0050] In this embodiment, step S208 specifically includes: Determine whether the heating demand is met based on the target load information; If the heating demand is met based on the target load information, at each first preset time interval, according to the first sorting result, a third target number of heat pump units is determined from the air source heat pump system, and the third target number of heat pump units is controlled to start. The third target number is used to indicate the start of the third target number of heat pump units to meet the heating demand. If, based on the target load information, it is determined that the heating demand is not met and a first target number of heat pump units need to be turned on, the first target number of heat pump units is determined from the air source heat pump system according to the first sorting result, and the first target number of heat pump units is controlled to be turned on. If, based on the target load information, it is determined that the heating demand is not met and a second target number of heat pump units need to be shut down, the first sorting result is reversed to obtain the second sorting result. Based on the second sorting result, a second target number of heat pump units is determined from the air source heat pump system, and the second target number of heat pump units is controlled to shut down.
[0051] The determination of whether the heating demand is met based on the target load, as described above, will not be repeated here. When the heating demand is determined to be met based on the target load information, it indicates that the number of heat pump units currently running in the air source heat pump system can meet the heating demand. To avoid continuously running the same heat pump unit for an extended period, further increasing the cold island effect in the air source heat pump system, a third target number of heat pump units is determined according to the currently determined first sorting result every first preset time interval, and these units are controlled to start. Simultaneously, all heat pump units already running before this time are controlled to shut down. The first preset time interval can be set according to actual needs; in this embodiment, the specific value of the first preset time interval is not limited. For example, the first preset time interval can be 6 minutes.
[0052] In cases where the target load information indicates that the heating demand is insufficient and a first target number of heat pump units need to be activated, this indicates that the number of heat pump units currently activated in the air source heat pump system is insufficient. In this situation, to mitigate the cold island effect generated by the air source heat pump system, when controlling the activation of the first target number of heat pump units, since the first sorting result already includes a sequence of all heat pump units in the air source heat pump system ranked from least to most influential in terms of their impact on the cold island effect, no further operation is needed on the first sorting result. Therefore, the first target number of heat pump units with the lowest impact on the cold island effect can be prioritized for activation based on the first sorting result. Similarly, if the target load information indicates that the heating demand is insufficient and a second target number of heat pump units need to be shut down, this indicates that the number of heat pump units currently activated in the air source heat pump system is excessive. To mitigate the island effect generated by the air-source heat pump system, when shutting down the second target number of heat pump units in the system, the first ranking result must be reversed to obtain the second ranking result (i.e., a sequence of all heat pump units in the system ranked from largest to smallest in terms of their impact on the island effect). Based on this second ranking result, the second target number of heat pump units with the greatest impact on the island effect are prioritized for shutdown. It should be noted that the degree of impact of the heat pump units on the island effect is positively correlated with the influence of ambient wind and / or the temperature of the heat exchange modules within the heat pump units.
[0053] This embodiment provides a control method for an air source heat pump system. When controlling the heat pump units in an air source heat pump system operating in heating mode, the method considers the influence of the ambient wind in the outdoor environment on each heat pump unit, which in turn affects the cold island effect generated by the air source heat pump system. By monitoring the ambient wind information of the outdoor environment where the air source heat pump system is located, the method obtains a ranking result of the degree of influence of all heat pump units in the entire air source heat pump system on the cold island effect based on the monitored ambient wind information. Then, based on the ranking result and the determined target load information corresponding to the air source heat pump system, the method controls the heat pump units in the air source heat pump system to improve the cold island effect generated by the array-type air source heat pump, thereby improving the operating efficiency of the air source heat pump system and reducing the operating energy consumption of the air source heat pump system.
[0054] refer to Figure 3 , Figure 3This is a flowchart illustrating another control method for an air source heat pump system provided in this application embodiment. The control method for an air source heat pump system provided in this application embodiment includes the following steps: S301: When the air source heat pump system is running in heating mode, obtain the ambient wind information of the outdoor environment where the air source heat pump system is located. The ambient wind information includes the actual wind speed and the actual wind direction of the ambient wind.
[0055] In this embodiment, step S301 is the same as step S201 described above, and can be found in the following reference. S302: Determine whether the actual wind speed is less than or equal to the second preset wind speed.
[0056] S303: When the actual wind speed is less than or equal to the second preset wind speed, obtain the second actual temperature of the heat exchange module in each heat pump unit.
[0057] S304: Sort all heat pump units in the air source heat pump system according to the second actual temperature of the heat exchange module in the heat pump unit from largest to smallest, so as to obtain the first sorting result among all heat pump units in the air source heat pump system.
[0058] S305: When the actual wind speed is greater than the second preset wind speed, determine whether the actual wind speed is less than or equal to the first preset wind speed, and the second preset wind speed is less than the first preset wind speed.
[0059] Regarding steps S302 to S305 above, to more accurately determine whether the air source heat pump system is affected by the ambient wind of the outdoor environment, a first preset wind speed and a second preset wind speed are defined, with the second preset wind speed being less than the first preset wind speed. The first and second preset wind speeds can be set according to actual needs; in this embodiment, the specific values of the first and second preset wind speeds are not limited. When the actual wind speed is less than or equal to the second preset wind speed, the influence of the ambient wind of the outdoor environment on the heat pump unit can be ignored; only the influence of the temperature of the evaporator module in the heat pump unit is considered, thereby improving the accuracy of the determined first sorting sequence. When using the first sorting sequence to control the heat pump unit, the cold island effect generated by the air source heat pump system can be better mitigated. Based on the obtained third actual temperature of the heat exchange module in each heat pump unit, all heat pump units in the air source heat pump system are sorted in ascending order of the third actual temperature of the heat exchange module to obtain the first sorting sequence.
[0060] S306: When the actual wind speed is less than or equal to the first preset wind speed, obtain the first actual temperature of the heat exchange module in each heat pump unit.
[0061] S307: Determine the first ranking result among all heat pump units in the air source heat pump system based on the actual wind direction and the first actual temperature of the heat exchange modules in each heat pump unit.
[0062] S308: When the actual wind speed is greater than the first preset wind speed, determine the target comparison result between the actual wind direction and the preset wind direction.
[0063] S309: Based on the target comparison results, sort all heat pump units in the air source heat pump system to obtain the first sorting result.
[0064] S310: Determine the target load information corresponding to the air source heat pump system.
[0065] S311: Control each heat pump unit in the air source heat pump system according to the first sorting result and target load information.
[0066] For steps S306 to S311, which are the same as steps S202 to S208, please refer to the above description for details. They will not be repeated here in this embodiment.
[0067] This embodiment provides a control method for an air source heat pump system. When controlling the heat pump units in an air source heat pump system operating in heating mode, the method considers the influence of the ambient wind in the outdoor environment on each heat pump unit, which in turn affects the cold island effect generated by the air source heat pump system. By monitoring the ambient wind information of the outdoor environment where the air source heat pump system is located, the method obtains a ranking result of the degree of influence of all heat pump units in the entire air source heat pump system on the cold island effect based on the monitored ambient wind information. Then, based on the ranking result and the determined target load information corresponding to the air source heat pump system, the method controls the heat pump units in the air source heat pump system to improve the cold island effect generated by the array-type air source heat pump, thereby improving the operating efficiency of the air source heat pump system and reducing the operating energy consumption of the air source heat pump system.
[0068] The following is an example for reference. Figure 4 The control process of an air source heat pump system will be described in detail below: When the air source heat pump system is running in heating mode, if the indoor temperature is less than the target indoor temperature - △T0 (△T0 is 1℃ by default, adjustable from 0 to 5℃); Outdoor wind speed sensors detect the actual wind speed in the environment, and outdoor wind direction sensors detect the actual wind direction in the environment. If the actual wind speed is less than or equal to the second preset wind speed of 2m / s (adjustable), it will be unaffected by the ambient wind speed by default. Every T1 (T1=10min adjustable), all heat pump units in the air source heat pump system will be sorted in descending order of the temperature of the heat exchange modules in the heat pump units to obtain the first sorting result. When it is determined that the heat pump units no longer need to be turned on or turned off, every T2 (T2=6min adjustable), the heat pump units will be switched on and off according to the order of the first sorting result. When it is determined that the heat pump units need to be turned on or off, the heat pump units will be turned on again according to the first sorting result or turned off in reverse order of the first sorting result.
[0069] If the actual wind speed is greater than the second preset wind speed by 2 m / s and less than or equal to the first preset wind speed by 5 m / s (adjustable), the influence of wind speed and the temperature of the heat exchange modules in the heat pump unit must be considered simultaneously. The unit array is numbered according to the actual wind direction and denoted as Bx. It is then sorted a second time from largest to smallest temperature according to the heat exchange modules in the heat pump unit and denoted as By. A third sorting is performed according to the value of z=x+y from smallest to largest to obtain the first sorting result. When it is determined that the heat pump unit no longer needs to be turned on or turned off, the heat pump unit is switched on and off every T2 (T2=6min adjustable) according to the order of the first sorting result. When it is determined that the heat pump unit needs to be turned on or turned off, the heat pump unit is turned on again according to the first sorting result or turned off in the reverse order of the first sorting result.
[0070] If the actual wind speed is greater than the first preset wind speed by 5 m / s, then determine whether the actual wind direction is the first preset wind direction. If the actual wind direction is the first preset wind direction (affected by both wind direction and the temperature of the heat exchange modules in the heat pump unit), number the heat pump unit according to the first preset wind direction, denoted as Bx, and then sort it a second time from largest to smallest according to the temperature of the heat exchange modules in the heat pump unit, denoted as By; sort it a third time from smallest to largest according to the value of z=x+y, to obtain the first sorting result; when it is determined that the heat pump unit no longer needs to be turned on or turned off, every T2 (T2=6min adjustable), switch the start and stop of the heat pump unit according to the order of the first sorting result; when it is determined that the heat pump unit needs to be turned on or turned off, turn on the heat pump unit according to the first sorting result or turn off the heat pump unit in reverse order of the first sorting result.
[0071] If the actual wind direction is the second preset wind direction (affected by the wind direction), the unit array is sorted according to the second preset wind direction to obtain the first sorting result; when it is determined that the heat pump units no longer need to be turned on or turned off, the heat pump units are switched on and off in the order of the first sorting result every T2 (T2=6min adjustable); when it is determined that the heat pump units need to be turned on or turned off, the heat pump units are turned on again according to the first sorting result or turned off in the reverse order of the first sorting result.
