Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

First, the configuration of a device equipped with an evaporative cooling function will be described. Fig. 1 is a schematic structural diagram of a device with an evaporative cooling function in an embodiment of the present application. Please refer to FIG. 1 , in some embodiments, the device with evaporative cooling function includes a natural cooling heat exchange part and a supplementary cooling part. The natural cooling heat exchange part mainly includes heat exchange core, spray water pump, spray system, heat exchange fan, water tray, water level switch, sewage valve, water supply valve, outdoor temperature sensor, etc. The supplementary cooling part mainly includes indoor air supply fans, compressors, etc.

When the outdoor temperature is low, only the indoor air supply fan and heat exchange fan operate. The indoor high-temperature return air passes through the heat exchange core to exchange heat with the outdoor low-temperature air and then is cooled and sent indoors. The outdoor low-temperature air passes through the heat exchange core to exchange heat with the indoor high-temperature return air and then is discharged to the outdoor environment; Cooling by the heat exchange fan cannot meet the indoor temperature requirements. At this time, the spray water pump needs to be turned on to cool the outdoor air from high temperature and low humidity to low temperature and high humidity through the spray system. At this time, the indoor high temperature return air passes through the heat exchange core and the outdoor low temperature high temperature. The humid air is cooled and sent indoors after heat exchange, and the outdoor low-temperature and high-humidity air is discharged to the outdoor environment after heat exchange with the indoor high-temperature return air through the heat exchange core; when the outdoor temperature rises further, only natural heat exchange cannot meet the indoor temperature. Therefore, the supplementary cooling part is turned on at the same time of natural heat exchange to supplement the cooling capacity, so as to achieve the required indoor temperature.

In the spray mode and spray + supplementary cooling mode, since the outdoor air needs to be cooled by evaporating spray water, the ion concentration of the circulating water in the spray water tray will become higher and higher, so it needs to be connected to the water tray The circulating water is treated for sewage, and the ion concentration of the circulating water in the water receiving tray is kept below a certain value.

In order to ensure the normal operation of the sprinkler system during sewage discharge (that is, to ensure the cooling capacity of the equipment first), the current conventional sewage discharge method is the method of diluting sewage, that is, when the ion concentration of the sewage in the water receiving tray reaches a certain concentration, the water receiving tray will be removed. Part of the sewage in the water is drained, and then some new water is added, which will dilute the ion concentration of the sewage in the water receiving tray, but this method of sewage discharge cannot make the ion concentration of the sewage in the water receiving tray reach a lower level. Therefore, the frequency of sewage discharge will be higher, and the sewage consumption will be higher.

Based on the above, the embodiment of the present application provides a sewage discharge control method, device, equipment and medium applied to the above-mentioned equipment with evaporative cooling function, which can ensure the cooling capacity of the equipment, reduce the frequency of sewage discharge, and further reduce the sewage consumption and achieve water saving. Purpose. The specific pollution control method will be described in detail in the following examples.

In a first aspect, the embodiments of the present application provide a pollution control method. Fig. 2 is a schematic flow chart of a pollution control method in an embodiment of the present application. Please refer to Figure 2, in some embodiments, the pollution control method includes:

Step S110: Obtain the ambient temperature of the device with the evaporative cooling function.

Step S120: When the ambient temperature of the equipment with the evaporative cooling function is higher than the first preset temperature, control the sewage in the water receiving tray to be discharged in the first sewage discharge mode.

Step S130: When the ambient temperature of the equipment with evaporative cooling function is lower than the first preset temperature, control the sewage in the water receiving tray to be discharged in the second sewage discharge method according to the preset condition.

In some embodiments, the execution subject of the emission control method may be a control device provided in a device with an evaporative cooling function. The control means may include a processor and a memory for controlling various components of the evaporative cooling device to work in concert.

A device with an evaporative cooling function may include a temperature detection module set outdoors, such as the outdoor temperature sensor shown in FIG. 1 . The ambient temperature can be obtained through the temperature detection module. After acquiring the ambient temperature, it is determined whether the ambient temperature is higher than the first preset temperature. Optionally, the ambient temperature can be outdoor dry bulb temperature (usually there must be), outdoor wet bulb temperature (if any), condensation temperature (if any), condensation pressure (if any), condensation temperature difference (if any), condensation One of differential pressure (if any).

When the ambient temperature is higher than the first preset temperature, the sewage in the water receiving tray is controlled to be discharged in the first sewage discharge mode. The first sewage discharge method can be the conventional diluted sewage discharge method, that is, when the ambient temperature is high, the conventional diluted sewage discharge method is still used, and the spray system does not stop running to ensure the cooling capacity of the equipment.

When the ambient temperature is lower than the first preset temperature, the sewage in the water receiving tray is controlled to be discharged in the second sewage discharge mode according to the preset condition. Among them, the preset condition can be a condition to ensure the cooling capacity of the equipment, and the second sewage discharge method can be a sewage discharge mode with a lower frequency than that of diluted sewage discharge, so as to ensure the cooling capacity of the equipment while reducing the frequency of sewage discharge, thereby reducing sewage discharge Consumption, to achieve the purpose of water saving.

In addition, in the embodiment of the present application, by judging whether the ambient temperature is higher than the first preset temperature, the sewage in the water receiving tray can be automatically controlled to be discharged in the first sewage discharge method or the second sewage discharge method, which has a high degree of automation and does not require manual intervention, saving Labor cost.

In some embodiments, the sewage in the water receiving tray is controlled to be discharged in the second sewage discharge method, including:

Control the sprinkler system to stop running, and control the emptying of sewage in the water tray.

That is, when the ambient temperature is low, you can consider controlling the sprinkler system to stop running, and consider draining the sewage directly and then replenishing new water. After each sewage discharge cycle, the initial ion concentration in the water receiving tray is as low as the new water replenished , so the entire sewage discharge cycle will be longer, that is, the frequency of sewage discharge is low, and the amount of sewage discharged each time is smaller than that of diluted sewage, so as to achieve the purpose of water saving.

As mentioned above, the sewage discharge in the second sewage discharge mode will control the sprinkler system to stop running. In order to ensure the cooling capacity of the equipment, it is necessary to consider whether the equipment can meet the air supply temperature requirements after the sprinkler system stops running during emptying and sewage discharge. Therefore, in some embodiments, the preset condition includes that the indoor supply air temperature is lower than the second preset temperature. Specifically, the device with the evaporative cooling function may also include a temperature detection module arranged at the indoor air supply place. When the ambient temperature is lower than the first preset temperature, the indoor air supply temperature can be acquired through the temperature detection module. After obtaining the indoor air supply temperature, it is determined whether the indoor air supply temperature is lower than the second preset temperature. When the indoor air supply temperature is lower than the second preset temperature, it means that the cooling capacity of the equipment can meet the requirements, and the sewage in the water receiving tray is controlled to be discharged in the second sewage discharge method, so as to reduce the frequency of sewage discharge while ensuring the cooling capacity of the equipment , thereby reducing the sewage consumption and achieving the purpose of water saving.

It should be noted that multiple devices with evaporative cooling function may be installed in one room. If one of the equipment adopts emptying and sewage discharge (that is, the second sewage discharge method), the sprinkler system will stop running, and at this time, the common supply air temperature of multiple equipment will fluctuate to a certain extent. Therefore, in some embodiments, the preset condition includes at least one adjacent piece of equipment not blowing down. Specifically, before performing sewage discharge in the second sewage discharge mode, it is possible to first determine whether the adjacent equipment group of the equipment is performing sewage discharge, for example, to determine whether the equipment adjacent to the equipment (that is, 2 units on the left and 2 units on the right side) is performing sewage discharge . If there is at least one adjacent equipment that has not discharged sewage, that is, the sprinkler system of one or more adjacent equipment is in normal operation, then the equipment can be emptied and discharged to prevent all equipment in the same area from stopping spraying at the same time. The shower causes the room temperature to be too high.

It can be understood that, in the above embodiments, at least one adjacent device does not perform sewage discharge as the judgment standard. In actual application scenarios, at least two or at least three adjacent devices may not perform sewage discharge as the judgment standard to prevent the same area from Multiple devices can stop spraying at the same time, so as to more effectively prevent the indoor temperature from being too high.

In some embodiments, the pollution control method also includes:

If the adjacent equipment is discharging sewage, wait for the adjacent equipment to discharge sewage in the second sewage discharge mode.

If the adjacent equipment is emptying and blowing down, that is, the sprinkler system of the adjacent equipment stops running, wait for the other adjacent equipment to complete the blowdown before starting the blowdown, so as to prevent all the equipment in the same area from stopping spraying at the same time and causing the indoor temperature to be too high. high.

It can also be understood that, in the above embodiment, the judging standard is that all adjacent devices are discharging sewage. In actual application scenarios, the judging standard may be that devices that are a little less than all the neighboring devices are discharging sewage.

Fig. 3 is a schematic flowchart of a pollution control method in another embodiment of the present application. Please refer to FIG. 3 , in some embodiments, before controlling the sewage in the water receiving tray to be discharged in the second sewage discharge mode, the sewage discharge control method further includes:

Step S140: Detect whether the compressor is turned on.

Step S150: If the compressor is not turned on, control the compressor to turn on.

In some embodiments, in order to prevent the indoor supply air temperature of the equipment from being too high after the sprinkler system stops running, it is detected whether the compressor of the equipment is turned on before the sprinkler system is controlled to stop running. If the compressor is not turned on, the compressor is controlled to start in advance, so that the compressor can be quickly loaded after the sprinkler system stops running, responding to changes in the indoor supply air temperature of the equipment, thereby reducing the indoor supply air temperature.

In some embodiments, before discharging the sewage in the water receiving tray, the pollution control method further includes:

Obtain the ion concentration of the sewage in the water receiving tray;

If the ion concentration is greater than or equal to the preset concentration, the sewage in the water receiving tray is discharged.

An ion concentration detection module, such as an ion concentration detector, can be installed in the water receiving tray to detect the ion concentration of the sewage in the water receiving tray in real time. When the ion concentration is greater than or equal to the preset concentration, and the sewage in the water receiving tray needs to be discharged, the steps of the method for controlling the discharge of sewage in the above-mentioned embodiments are executed.
