Example one
Fig. 1 is a flowchart illustrating a water pump operation control method according to an exemplary embodiment, as shown in fig. 1, the method including:
step S11, receiving a water pump operation scheme selected by a user;
step S12, controlling the operation of the water pump according to the water pump operation scheme selected by the user;
the water pump operation scheme comprises: the number of the water pumps and/or the connection mode of the water pumps.
It should be noted that the technical solution provided in this embodiment is applicable to a scene that needs to use a water pump to supply water, for example, is applied to a water-cooled air conditioner, a water-cooled fresh air blower, a water-cooled refrigerator, and the like.
The step S11 of receiving the water pump operation scheme selected by the user may be implemented by a set human-computer interaction module, and the step S12 of controlling the operation of the water pump according to the water pump operation scheme selected by the user may be implemented by a controller. When the technical scheme provided by the embodiment is applied to control of the air-conditioning water pump of the air-conditioning unit, the controller can be connected through the man-machine interaction module, and the controller is connected with the unit to realize the water pump operation control method.
The implementation manner of the human-computer interaction module includes but is not limited to: the method comprises the steps of touching a display screen, or adding a keyboard module to the display screen, or adding a voice recognition module to a display, and the like.

The connection mode of water pump includes: parallel, series, or a combination of parallel and series connections.
Taking the human-computer interaction module as a touch display screen as an example, the quantity and the series-parallel connection mode of the water pumps are set on the touch display screen, the touch display screen stores set data, and after the touch display screen is powered off and powered on, the stored set data are read, so that a user does not need to reset.
Taking two water pumps as an example, the difference between the series connection and the parallel connection of the two water pumps is as follows:
the water yield provided by the water pumps in series is different from that provided in parallel.
When the water pumps are connected in series, the water outlet of one water pump is communicated with the water inlet of the other water pump; when the water pumps are connected in parallel, the two water pumps operate independently.
When the water pumps are connected in series, if one water pump stops operating, the stopped water pump has certain resistance, and the water outlet supply quantity of the other water pump can be reduced; when the two water pumps are connected in parallel, the running water pump is stopped, and the water outlet supply quantity of the other water pump cannot be reduced.
Two small-sized water pumps are connected in parallel, and can replace a large-sized water pump to control;
two large-scale water pumps are connected in series and can replace one-in-one-out-two-model water pump parallel control (because one large-scale water pump is opened, when one large-scale water pump is not opened, the unopened water pump can generate certain resistance to the flow of chilled water, therefore, the two large-scale water pumps are connected in series and can replace one-in-one-out-two-model water pump parallel control).
It can be understood that when the number of the water pumps is one, the user does not need to set the connection mode of the water pumps. When the quantity of water pump is two at least, the user can set up or change the connected mode of current water pump.

when the number of the water pumps is one, if the air conditioning unit is started, the water pumps are started;
and when the number of the water pumps is one, if the air conditioning unit is shut down, the water pumps are shut down.
It can be understood that the water pump is only necessary to be turned on when the air conditioning unit is turned on, and the water pump is required to be turned off simultaneously when the air conditioning unit is turned off to save energy and reduce consumption.
The operation of the water pump is controlled according to the water pump operation scheme selected by the user, and the method comprises the following steps:
when the number of the water pumps is at least two, judging the connection mode of the water pumps;
and controlling the operation of the water pump according to the connection mode of the water pump.
In a specific practice, if the water pumps are installed in the air conditioning unit and the number of the water pumps is two, the controlling operation of the water pumps includes:
when the two water pumps are connected in parallel, if the air conditioning unit is started, the two water pumps are controlled to be started and stopped according to whether the temperature difference delta T1 between inlet water and outlet water of chilled water is greater than a first set temperature difference coefficient K (the unit of the temperature coefficient K);
when the two water pumps are connected in series, if the air conditioning unit is started, one water pump is controlled to be started, and after the air conditioning unit runs for a preset time, the other water pump is controlled to be started according to whether the deviation delta T2 between the outlet water temperature of the chilled water and the set temperature is greater than a second set temperature difference coefficient P (the unit of the temperature coefficient P);
and when the two water pumps are connected in parallel or in series, if the air conditioning unit is shut down, the two water pumps are closed.
It should be noted that the preset time period is set according to the user requirement, or set according to a historical experience value or experimental data. The set temperature is set according to historical empirical values or experimental data.
Specifically, whether according to the refrigerated water business turn over water difference Δ T1 be greater than setting for the temperature difference coefficient K, control two water pump open and close, include:
if the temperature difference delta T1 of the inlet and outlet water of the chilled water is larger than a first set temperature difference coefficient K, controlling the two water pumps to be started;
and if the temperature difference delta T1 of the inlet and outlet water of the chilled water is less than or equal to a first set temperature difference coefficient K, controlling a water pump to be started.
It can be understood that if the temperature difference delta T1 between the inlet water and the outlet water of the chilled water is greater than a first set temperature difference coefficient K, the temperature difference between the inlet water and the outlet water of the chilled water is large, the supply flow rate of the chilled water needs to be increased, and at the moment, the two water pumps are controlled to be started; if not, the temperature difference of the inlet and outlet water of the chilled water is small, only a small chilled water flow is needed to supply the load, and at the moment, one water pump is controlled to be started.
Specifically, the controlling whether another water pump is started or not according to whether the deviation Δ T2 between the outlet water temperature of the chilled water and the set temperature is greater than a second set temperature difference coefficient P includes:
and if the deviation delta T2 between the outlet water temperature of the chilled water and the set temperature is greater than a second set temperature difference coefficient P, controlling the other water pump to be started, otherwise, not starting the other water pump.
It can be understood that if the deviation Δ T2 between the chilled water outlet temperature and the set temperature is greater than the second set temperature difference coefficient P, which indicates that the deviation between the chilled water outlet temperature and the set outlet temperature is large, the supply flow rate of the chilled water needs to be increased, and then the two water pumps are started; if not, the outlet water temperature of the chilled water is close to the set outlet water temperature, and only one water pump is started.
It should be noted that, in a specific practice, the first set temperature difference coefficient K and the second set temperature difference coefficient P may be set to an adjustable value according to a user's requirement. Or the first set temperature difference coefficient K and the second set temperature difference coefficient P are set as fixed values according to historical experience values or experimental data.
In particular practice, the first set temperature difference coefficient K and the second set temperature difference coefficient P may be the same or different.
In specific practice, when the number of the water pumps is at least two, if any one of the water pumps fails, the failed water pump is closed, and the rest of the water pumps are kept running continuously.
It can be understood that when a plurality of water pumps work simultaneously, when one water pump breaks down, the other water pump can be replaced equivalently, and the reliability of the control system is improved.
It can be understood that, the technical scheme that this embodiment provided, the control method of water pump when having considered different water pump quantity and different connected mode to refer to chilled water business turn over water difference in temperature and chilled water leaving water temperature and carry out differentiation control to the water pump operation scheme under the different connected mode, thereby realize carrying out the adaptability control to the water pump of different quantity and/or the water pump of different connected mode, and then satisfy the water supply demand of different engineering projects, practiced thrift development cost, user experience is good, the satisfaction is high.
