The double-combined-supply system is provided with a plurality of execution unit machines, and each execution unit machine is provided with a water pump, a compressor, a fan, a heat exchanger and the like.
The water flow is an important factor influencing the heat exchange effect of the two-combined-supply system, generally, the pressure difference between the water inlet and the water outlet of the heat exchanger and the water flow of the two-combined-supply system are in a unitary quadratic function relationship, and the water flow of the two-combined-supply system can be determined when the pressure difference between the water inlet and the water outlet of the heat exchanger is determined.
The water pump control method for the two-combined-supply system provided by this embodiment obtains the actual pressure drop of the two-combined-supply system at intervals, that is, at preset time units, where the actual pressure drop refers to the pressure difference between the water inlet and the water outlet of the heat exchanger in the execution unit machine. The preset time unit is set by a researcher or a user, and is generally set to 40 seconds, 50 seconds, 55 seconds, or the like.
Further, step S10 includes:
step a, acquiring the water inlet pressure and the water outlet pressure of each execution unit machine in the two combined supply system every other preset time unit;
it should be noted that the water inlet and the water outlet of each execution unit machine heat exchanger of the two-combined supply system are respectively provided with a pressure sensor for useIn detecting the pressure of the incoming and outgoing water, i.e. P, due to the flow of waterIntoAnd PGo out. Acquiring P of each execution unit machine every other preset time unitIntoAnd PGo out。
Step b, calculating the difference between the water inlet pressure and the water outlet pressure of each execution unit machine to obtain a plurality of water inlet and outlet pressure drops;
p acquired belonging to the same execution unit machineIntoAnd PGo outSubtracting, calculating the difference between the water inlet pressure and the water outlet pressure of each execution unit machine to obtain the water inlet and outlet pressure drop of each execution unit machine, namely the water inlet and outlet pressure drop is PGo into-PGo out。

When the two-combined-supply system is started, the water pump of one execution unit machine in the two-combined-supply system is also in a starting state, and other water pumps are still in a closing state. Generally, the water pump No. 1 is started firstly, the obtained water inlet and outlet pressure drop of the execution unit machine No. 1 is used as the actual pressure drop, and whether a water pump in the two combined supply systems is additionally started or not is judged according to the actual pressure drop. When a plurality of water pumps are started, the pressure drop of water inlet and outlet of the execution unit machine to which the water pumps belong is determined as actual pressure drop, and whether a water pump is started again is judged according to the actual pressure drop.
Further, step S20 further includes:
d, if the actual pressure drop is less than or equal to a first preset pressure drop and greater than or equal to a second preset pressure drop, increasing to operate a water pump;
and e, if the actual pressure drop is smaller than the second preset pressure drop and is greater than or equal to a third preset pressure drop, operating all the water pumps in the two-combined-supply system.

When the actual pressure drop is less than or equal to the first preset pressure drop and greater than or equal to the second preset pressure drop, the water flow needs to be increased to improve the heat exchange effect of the two-combined-supply system, and the water flow in the two-combined-supply system can be increased by additionally operating a water pump.
And when the actual pressure drop is smaller than the second preset pressure drop and is larger than or equal to the third preset pressure drop, the water flow in the two combined supply systems is too small, all water pumps which are not operated in the two combined supply systems are started, and the water flow in the two combined supply systems is increased.

When the actual pressure drop is larger than the first preset pressure drop and smaller than or equal to the fourth preset pressure drop, the current water flow of the two combined supply systems is proper, the heat exchange effect of the two combined supply systems is good, the number of the water pumps which are currently running is maintained, and one water pump does not need to be started.
And g, if the actual pressure drop is larger than the fourth preset pressure drop, closing a running water pump.
When the actual pressure drop is larger than the fourth preset pressure drop, the fact that the two-combined-supply system is in a low load state is shown, the current water flow is too large, the number of running water pumps can be reduced, waste of water pump resources is reduced, generally, one water pump is turned off at first, the actual pressure drop is obtained continuously, whether the water pumps are turned off continuously is judged, it needs to be shown that the turning off of the water pumps is also turned off step by step, and the fact that the turning off of the water pumps affects the heat exchange efficiency of the two-combined-supply unit is avoided.
