Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

At present, a spray cooling method can be adopted to spray cooling liquid to a condenser, and heat is taken away by means of evaporative cooling, so that the refrigerating capacity of an internal machine is improved, and the running power consumption of a compressor is reduced. Although the spraying method can effectively improve the heat exchange efficiency of the outer machine heat exchanger, the spraying system can consume a large amount of water resources, and at the moment, an intermittent spraying method can be generally adopted, so that the consumption of the water resources can be effectively reduced, and the higher heat exchange efficiency of the condenser is ensured.

However, the conventional intermittent spraying method does not consider the situation of the water pump, however, when the intermittent spraying mode is adopted, the water pump needs to be frequently started and stopped, and at the moment, the water pump is easy to break down, so that the service life of the water pump is shortened; in addition, when utilizing the solenoid valve on the water route to carry out the frequent start-stop of water pump, the water pump can lead to waterway system water pressure height to vibrate because of the continuous operation, reduces water pump and waterway system's reliability.

Therefore, the traditional spray cooling mode has the problems of serious water consumption, single spray mode and short service life of the water pump. Based on the above, the embodiment of the invention provides a control method and device of a spraying system and electronic equipment, and particularly relates to a water-saving spraying cooling device with a water pump and a control method thereof. Moreover, the problems of vibration and damage of a spraying system can be avoided while intermittent spraying can be effectively realized.

For the convenience of understanding the present embodiment, a detailed description will be given to a control method of a spraying system disclosed in the present embodiment.

The first embodiment is as follows:

the embodiment of the invention provides a control method of a spraying system, which is applied to the spraying system, wherein the spraying system comprises a plurality of nozzles. The spraying system provided by the embodiment of the invention can comprise equipment such as a water tank, a water pump, a detection module, a control module, an electromagnetic valve, a water pipe, a nozzle and an external unit, wherein: the water pump may be a booster pump for increasing the waterway pressure when the water supply pressure is low. The spray nozzles are used for spraying the cooling liquid on the surface of the heat exchanger.

The detection module is used for acquiring and receiving a spraying start-stop signal and a corresponding spraying mode, wherein the spraying mode comprises continuous spraying and intermittent spraying. In the continuous spraying time period, spraying liquid is continuously sprayed to the surface of the heat exchanger from the nozzle, so that evaporative cooling is realized; and the intermittent spraying is spraying time Tx and spraying stopping time Ty, and spraying stopping operations are sequentially and circularly executed.

The control module is used for receiving the signal of the detection module and controlling the start and stop of the water pump and the electromagnetic valve so as to realize a corresponding spraying mode. The detection module and the control module can be arranged on a circuit board, the detection module can be in communication connection with the outer machine mainboard and can obtain real-time monitoring parameters in the outer machine mainboard, and then the real-time monitoring parameters are compared with a control table preset in the detection module to judge whether the outer machine mainboard is started or stopped and judge a corresponding spraying mode; the control module mainly comprises an electromagnetic relay, is connected with the water pump and the electromagnetic valve through leads, and controls the on-off of the water pump and the electromagnetic valve to further close the corresponding device.

The solenoid valve in this embodiment may have different setting modes, and the solenoid valve is a two-way solenoid valve or a three-way solenoid valve. The three-way electromagnetic valve is divided into A, B, C three ports, wherein port A is communicated with the main waterway, ports B and C are respectively communicated with the two branches, and the two branch waterways are switched to be closed and opened by switching between the AB and AC passages; when the spraying is not started in the initial state, the two-way electromagnetic valve and the water pump are both in a closed state, and the three-way electromagnetic valve AB is communicated.

Based on the above description, referring to the flowchart of a control method of a spraying system shown in fig. 1, the control method of the spraying system includes the following steps:

step S102, determining the spraying modes of a plurality of nozzles; wherein, the spray mode of the nozzle comprises an intermittent spray mode and a continuous spray mode.

The spraying mode of each nozzle in the spraying system can be input by a user through a button on the air conditioner, a remote controller of the air conditioner or an application program of the terminal equipment, and the spraying system can determine the spraying mode of the nozzle by using the detection module.

Wherein, the spray mode of the nozzle can comprise a continuous spray mode or an intermittent spray mode. A continuous spray mode may be understood as a mode in which liquid in the tank flows continuously from the spray nozzles, and an intermittent spray mode may be understood as a mode in which liquid in the tank flows intermittently from the spray nozzles. Wherein, the liquid in the water tank can be cooling water or water, and the intermittent spraying mode can set different spraying time and intermittent time, for example: the spraying time is 3 seconds, the rest time is 6 seconds, it can be understood that 0-3 seconds of liquid flows out from the nozzle, 3-9 seconds of liquid stops flowing out from the nozzle, and so on.

And step S104, adjusting the spraying time and the spraying stopping time of the nozzles in the intermittent spraying mode so that the plurality of nozzles stop spraying at different times.

When the spraying mode is set, the spraying time and the spraying stopping time of the nozzles of each intermittent spraying mode can be the same or different, for example: the spraying time of the first nozzle in the intermittent spraying mode is 3 seconds, and the spraying stopping time is 5 seconds; the spraying time of the second nozzle in the intermittent spraying mode is 6 seconds, the spraying stopping time is 5 seconds, and the like.

In order to ensure the stability of the water pressure of the waterway system, the nozzles in the intermittent spraying mode need to be uniformly adjusted so as to ensure that the nozzles stop spraying at different times. As long as a plurality of nozzles do not stop spraying at the same time, the water pump can continuously operate, and therefore the water pump does not need to be started and stopped frequently.

Specifically, the adjusted nozzles in the intermittent spray mode may have the same spray time and the same spray stop time, and the spray time and the spray stop time may have the same value. For example, assuming that the first nozzle and the second nozzle are both in the intermittent spraying mode, the spraying time of the adjusted first nozzle and the adjusted second nozzle is both 3 seconds, and the spraying stopping time is also both 3 seconds.

And step S106, controlling the plurality of nozzles to perform spraying operation based on the spraying mode.

For example, if the spray mode of the spray nozzle is a continuous spray operation, the solenoid valve corresponding to the spray nozzle may be opened to allow the liquid in the water tank to continuously flow out of the spray nozzle.

If the spray mode of the nozzles is the intermittent spray operation, since the spray time and the spray stop time of the nozzles of each intermittent spray mode are the same, X seconds are assumed. At this time, the nozzles in the intermittent spraying mode can be divided into a first spraying nozzle and a first spraying stopping nozzle which are the same in number or different in number by one, the first spraying nozzle is controlled to spray for X seconds, and the first spraying stopping nozzle does not spray at this time; later the control stops the nozzle that spouts earlier and sprays X seconds, and the nozzle that sprays earlier at this moment does not spray to analogize to this, when realizing that the intermittent type sprays, guarantee that waterway system water pressure can not appear high-low vibration to improve waterway system water pressure's stability, can also realize spraying system's multiple mode of spraying.

According to the control method of the spraying system provided by the embodiment of the invention, after the spraying modes of the plurality of nozzles in the spraying system are determined, the spraying time and the spraying stopping time of the nozzles in the continuous spraying mode can be adjusted, so that the plurality of nozzles do not stop spraying at the same time, and the plurality of nozzles are controlled to perform spraying operation based on the spraying modes. In the mode, multiple spray modes are realized when a plurality of nozzles exist in the spray system, and the spray is stopped at different times due to the plurality of nozzles, so that the continuous operation of the water pump can be ensured, the optimal spray cooling effect is realized while the optimal water saving amount is ensured, the service life of the water pump is prolonged, and the reliability of a water path system is improved.

Example two:

the present embodiment provides another method for controlling a spraying system, which is implemented on the basis of the foregoing embodiments, and as shown in a flowchart of another method for controlling a spraying system shown in fig. 2, the method for controlling a spraying system in the present embodiment includes the following steps:

step S202, detecting the state of each outdoor unit through a detection module; and determining the spraying mode of the nozzle corresponding to the outer unit based on the state of the outer unit.

Referring to the schematic diagram of one spraying system shown in fig. 3 and the schematic diagram of another spraying system shown in fig. 4, the detection module 1 in this embodiment is configured to obtain a received spraying start-stop signal and a corresponding spraying mode, where the spraying mode includes a continuous spraying mode and an intermittent spraying mode. In addition, the spraying system further comprises a control module 2, the control module 2 is connected with the detection module 1, the control module 2 is used for receiving signals of the detection module 1 and controlling the water pump 3 and the solenoid valves (the first solenoid valve 41 and the second solenoid valve 42) to start and stop, so that corresponding spraying modes are realized, for example: and controlling the plurality of nozzles to perform spraying operation based on the spraying mode through the control module. Further, the water tank 7 is used for supplying water.

As shown in fig. 3 and 4, at least one nozzle in the present embodiment corresponds to an outer unit, the first nozzle 51 in fig. 3 corresponds to a first outer unit 61, the second nozzle 52 corresponds to a second outer unit 62, and the first nozzle 51 and the second nozzle 52 in fig. 4 correspond to the same outer unit 6.

First, the present embodiment will be described by taking the case of fig. 3 as an example, and the first and second

outdoor units

61 and 62 in fig. 3 are not simply referred to as an outdoor unit, but are collectively referred to as one or more outdoor units, and the first and

second nozzles

51 and 52 are also not simply referred to as one nozzle, but are collectively referred to as one or more nozzles. The first outdoor unit 61 and the second outdoor unit 62 are connected in parallel.

And step S204, adjusting the spraying time and the spraying stopping time of the nozzles in the intermittent spraying mode so that the plurality of nozzles stop spraying at different times.

Specifically, the spray time and the spray stop time of the nozzles of the intermittent spray mode can be adjusted by the following equations: tx0 ═ max (Tx1, Tx2, … Txn); ty0 ═ min (Ty1, Ty2, … Tyn); tx min (Tx0, Ty 0).

Wherein n is the number of nozzles in the intermittent spray mode, Tx is the spray time of the nozzles in the adjusted intermittent spray mode, Ty is the spray stop time of the nozzles in the adjusted intermittent spray mode, Txi is the spray time of the nozzle in the ith intermittent spray mode, Tx0 is the maximum value of the spray time of the nozzles in the intermittent spray mode, Tyi is the spray stop time of the nozzle in the ith intermittent spray mode, Ty0 is the minimum value of the spray stop time of the nozzles in the intermittent spray mode, max is the maximum value calculation, and min is the minimum value calculation.

In this embodiment, the spraying mode of the plurality of nozzles can have at least the following three conditions: (1) the spraying modes of the plurality of nozzles are all intermittent spraying modes. (2) The spraying modes of the plurality of nozzles are all continuous spraying modes. (3) The spraying mode of one part of nozzles is an intermittent spraying mode, and the spraying mode of the other part of nozzles is a continuous spraying mode.

Taking fig. 3 as an example, the spraying mode of the first nozzle 51 and the second nozzle 52 is an intermittent spraying mode, if both the two external units meet the intermittent spraying mode, the detection parameters are further compared with an intermittent spraying table preset in the circuit board, the intermittent spraying mode is determined, and the intermittent mode of the first external unit is defined as spraying Tx1 seconds and spraying Ty1 seconds; the intermittent mode of the second outdoor unit is defined as spraying Tx2 seconds and stopping spraying Ty2 seconds.

For example, the spray time and the spray off time of the nozzles of the continuous spray mode in fig. 3 may be adjusted by the following equations:

Tx0＝max(Tx1,Tx2)，Ty0＝min(Ty1,Ty2)，Tx＝Ty＝min(Tx0,Ty0)；

wherein Tx is spraying time, Ty is spraying stopping time, Tx1 is spraying time of the first nozzle, Ty1 is spraying stopping time of the first nozzle, Tx2 is spraying time of the second nozzle, Ty2 is spraying stopping time of the second nozzle, max is maximum value calculation, and min is minimum value calculation.

The intermittent spraying mode obtained by inquiring the preset table can ensure that the optimal water saving amount is achieved and the optimal spraying cooling effect is achieved, but in order to avoid that the water channel system is in a closed state when the water pump runs, the intermittent spraying mode needs to be further processed, the intermittent spraying mode with the optimal spraying cooling effect is found out, but the spraying water saving amount is slightly higher than the optimal water saving amount at the moment, and the water saving amount is still far lower than the water amount of continuous spraying; the intermittent spraying mode needs to meet the requirement that the second outdoor unit just stops spraying when the first outdoor unit sprays, and the second outdoor unit just starts spraying when the first outdoor unit stops spraying, namely the spraying time length is equal to the spraying stop time length.

Therefore, let Tx0 be max (Tx1, Tx2), Ty0 be min (Ty1, Ty2), and obtain the spraying time Tx and the spraying stop time Ty be Tx Ty-min (Tx0, Ty 0).

And step S206, controlling the plurality of nozzles to perform spraying operation based on the spraying mode.

The spraying system of this embodiment still includes water pump and a plurality of solenoid valve, and the solenoid valve and the nozzle one-to-one can be based on the solenoid valve that sprays mode control water pump and a plurality of nozzles and correspond to make a plurality of nozzles carry out the operation of spraying based on spraying the mode.

Specifically, if the plurality of spraying modes are all continuous spraying modes, the water pump can be turned on and the electromagnetic valves corresponding to the plurality of nozzles can be controlled to be continuously opened. For example: opening electromagnetic valves corresponding to the nozzles in the plurality of continuous spraying modes; and after the electromagnetic valves corresponding to the nozzles of the plurality of continuous spraying modes are opened for a preset first time, the water pump is opened.

As shown in fig. 3, when the detection module detects that one of the first outdoor unit 61 and the second outdoor unit 62 is turned on and satisfies the spraying condition, continuous spraying is performed, for example, the first outdoor unit 61 satisfies the condition and the second outdoor unit 62 does not satisfy the condition.

At the moment, the first electromagnetic valve is opened, the second electromagnetic valve is kept in a closed state, in order to avoid or reduce the water hammer effect caused by the fact that the electromagnetic valve is not completely opened and the waterway pressure caused by the operation of the water pump is severely changed, after the first electromagnetic valve is electrified for the first time T1, the control module controls the water pump to be opened, the cooling liquid is obtained from the water tank, the cooling liquid in the water pipe is sprayed onto the heat exchanger through the first electromagnetic valve at the nozzle, and spraying, evaporating and cooling are achieved.

When the detection module obtains a spraying stopping signal, the signal is transmitted to the control module to control the water pump to stop running; and after the water pump stops running for the first time T1, the first electromagnetic valve is closed, and the operation of the spraying system is finished. After the system is selected, T1 is usually a constant, but the value of T1 changes due to different water path systems and different start-stop times of the water pump and the electromagnetic valve, and the value range of T1 can be 1 s-T1 s-4 s.

Specifically, if the spraying mode of one part of the nozzles is an intermittent spraying mode and the spraying mode of the other part of the nozzles is a continuous spraying mode, the water pump can be turned on; controlling the electromagnetic valve corresponding to the nozzle in the continuous spraying mode to be continuously opened; and controlling the electromagnetic valves corresponding to the nozzles in the intermittent spraying mode to be opened or closed alternately.

For example, if the spray pattern of the first nozzles is a continuous spray pattern and the spray pattern of the second nozzles is an intermittent spray pattern; the electromagnetic valve of the first nozzle and the electromagnetic valve of the second nozzle can be opened; after the electromagnetic valve of the first nozzle is opened for a preset first time, the water pump is opened; and controlling an electromagnetic valve corresponding to the second nozzle based on the spraying time and the spraying stopping time of the intermittent spraying mode of the second nozzle so as to enable the liquid in the water tank to intermittently flow out of the second nozzle.

In the mode, the electromagnetic valve is firstly opened and then the water pump is opened, so that the water hammer effect caused by severe change of the water path pressure caused by the operation of the water pump due to incomplete opening of the electromagnetic valve can be avoided or reduced, and the service life of the water pump is prolonged.

As shown in fig. 3, when the detection module detects that both the first outdoor unit 61 and the second outdoor unit 62 satisfy the spraying start condition, it is further determined whether the mode is the intermittent spraying mode or the continuous spraying mode.

If one of the two modes is judged to be the continuous spraying mode, and the other is the intermittent spraying mode, the following operations are executed, taking the first external machine as an example to meet the intermittent spraying condition and the second external machine as an example to meet the continuous spraying condition.

If the second nozzle is judged to be in the intermittent spraying mode, the detection parameters are further compared with an intermittent spraying table preset in the circuit board, and an intermittent spraying mode is judged, namely spraying for Tx seconds and stopping spraying for Ty seconds. At the moment, the first electromagnetic valve and the second electromagnetic valve are both opened for the first time T1, and then the water pump is started to perform the spraying and cooling operation.

When the water pump is started for Tx time, the first electromagnetic valve is closed, and after Ty time is closed, the first electromagnetic valve is opened again, and the opening and closing of the first electromagnetic valve are controlled circularly according to the rule, wherein Tx can be larger than or equal to 1s and smaller than or equal to 6s, and Ty can be larger than or equal to 3s and smaller than or equal to 30 s. The second electromagnetic valve is in an open state in the whole process.

And if the two outer machines meet the continuous spraying mode, the first electromagnetic valve and the second electromagnetic valve are both opened, the water pump is started after T1 time, and the spraying and cooling operation is executed.

Specifically, if the spraying modes of the plurality of nozzles are all intermittent spraying modes, the water pump can be turned on, and the electromagnetic valves corresponding to the plurality of nozzles can be controlled to be alternately opened or closed.

If the spraying modes of the first nozzle and the second nozzle of the spraying system are both intermittent spraying modes, the electromagnetic valve and the water pump corresponding to the first nozzle can be opened, and the electromagnetic valve corresponding to the second nozzle can be closed; when the water pump is opened for the spraying time, opening the electromagnetic valve corresponding to the second nozzle, and closing the electromagnetic valve corresponding to the first nozzle; when the opening time of the electromagnetic valve corresponding to the second nozzle reaches the spray stopping time, opening the electromagnetic valve corresponding to the first nozzle, and closing the electromagnetic valve corresponding to the second nozzle; and when the opening time of the electromagnetic valve corresponding to the first nozzle reaches the spraying time, continuing to open the electromagnetic valve corresponding to the second nozzle and closing the electromagnetic valve corresponding to the first nozzle until a spraying closing signal is received.

In order to avoid or reduce the water hammer effect caused by the severe change of the water circuit pressure caused by the operation of the water pump due to the incomplete opening of the electromagnetic valve, after the first electromagnetic valve is electrified for T1 time, the control module controls the water pump to be opened, for example: and after the electromagnetic valve corresponding to the first nozzle is opened for a preset first time, the water pump is opened.

After the spraying signal is received, the first electromagnetic valve is opened, and the water pump is opened after the first time T1. And after the water pump is started for spraying time Tx, the second electromagnetic valve is opened, the first electromagnetic valve is closed, and after spraying time Tx, the first electromagnetic valve is opened, the second electromagnetic valve is closed, and the above operations are executed in a circulating manner, so that the intermittent spraying of the two machines is realized.

After receiving the spray stopping signal, the water pump can be turned off; and after the water pump is closed for the first time, closing the electromagnetic valve corresponding to the first nozzle and the electromagnetic valve corresponding to the second nozzle.

In addition, when one of the outdoor units meets the spraying closing condition (such as a first outdoor unit) in the running process of the outdoor units, the electromagnetic valve (a second outdoor unit) of the other outdoor unit is kept in an open state, continuous spraying is executed, the first electromagnetic valve is closed after the first time T1, and the first outdoor unit finishes spraying and cooling; if the second external machine also receives the spraying closing signal later, the water pump stops running, and the second electromagnetic valve is closed after the first time T1, and the whole spraying cooling system is finished.

Next, the present embodiment is described by taking the case of fig. 4 as an example, and is different from the spraying system in fig. 3 in that the number of the external units in fig. 4 is 1, and in this case, the number n of the nozzles is not less than 2, the nozzles are divided into two combinations, which are named as a first nozzle and a second nozzle, and the number of the nozzles is n1 and n2, respectively.

When n is an even number, n 1-n 2-n/2; when n is an odd number, n1 ═ n +1)/2, and n2 ═ n-1)/2. The intermittent spraying of different areas of the same external machine heat exchanger realizes effective water saving.

When the detection module detects a spraying opening signal, whether the spraying mode is a continuous spraying mode or an intermittent spraying mode is further judged, and if the spraying mode is the continuous spraying mode: at this moment, first solenoid valve and second solenoid valve are all opened, and behind the very first time T1, control module control water pump is opened, acquires the coolant liquid from the water tank, makes the coolant liquid in the water pipe spray the heat exchanger in nozzle department through two solenoid valves on, realize spraying evaporative cooling.

In the intermittent spraying mode, the detection parameters are further compared with an intermittent spraying table preset in the circuit board, an intermittent spraying mode, that is, spraying for Tx seconds, stopping spraying for Ty seconds, is determined, and the intermittent spraying mode is executed in a cyclic manner according to the rule.

At this time, the first solenoid valve is opened, the second solenoid valve is maintained in a closed state, and after the first time T1, the water pump is opened to perform the spray cooling operation. And after the water pump is started for Tx time, the second electromagnetic valve is opened, the first electromagnetic valve is closed, and after Tx time, the first electromagnetic valve is opened, the second electromagnetic valve is closed, the operations are executed in a circulating mode, and intermittent spraying of the two machines is achieved. Wherein Tx is Ty, and Tx is less than or equal to 1s and less than or equal to 6 s.

And after the detection module obtains a spraying stopping signal, the signal is transmitted to the control module to control the water pump to stop running. And after the water pump stops running for the first time T1, the first electromagnetic valve and the second electromagnetic valve are both closed, and the operation of the spraying system is finished. After the system is selected, T1 is usually a constant, but the value of T1 changes due to different water path systems and different start-stop time of the water pump and the electromagnetic valve, and the value range of T1 is that T1 is more than or equal to 1s and less than or equal to 4 s.

In addition, the present embodiment also provides a way to adjust the water pressure of the nozzle, such as: the water pump is a variable frequency water pump, and the water pressure of the nozzle can be adjusted through the water pump.

In the mode, the water pressure of the nozzle is adjusted by adjusting the fixed-frequency water pump or the pressure stabilizing valve, so that the liquid sprayed out of the nozzle has stable water pressure.
