[0002] Currently, the conventional sewage discharge method for equipment with an evaporative cooling function is the dilution sewage discharge method. That is, when the ion concentration of the sewage in the water receiving tray reaches a certain concentration, a part of the sewage in the water receiving tray is drained, and then a part of new water is replenished. In this way, the ion concentration of the sewage in the water receiving tray is diluted. However, this sewage discharge method cannot reduce the ion concentration of the sewage in the water receiving tray to a relatively low level, so the sewage discharge frequency is relatively high and the sewage consumption is relatively high.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0034] First, the structure of the device with evaporative cooling function is described. Figure 1 This is a schematic structural diagram of the device with evaporative cooling function in an embodiment of the present application. Please refer to Figure 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 a heat exchange core, a spray water pump, a spray system, a heat exchange fan, a water receiving tray, a water level switch, a sewage discharge valve, a water replenishing valve, an outdoor temperature sensor, etc. The supplementary cooling part mainly includes an indoor air supply fan, a compressor, etc.

[0035] When the outdoor temperature is relatively low, only the indoor air supply fan and the heat exchange fan operate. The high-temperature indoor return air is cooled and sent into the room after heat exchange with the low-temperature outdoor air through the heat exchange core, and the low-temperature outdoor air is discharged into the outdoor environment after heat exchange with the high-temperature indoor return air through the heat exchange core; when the outdoor temperature is slightly higher, cooling only through the heat exchange fan cannot meet the indoor temperature requirements. At this time, the spray water pump needs to be turned on, and the outdoor air is cooled from high temperature and low humidity to low temperature and high humidity through the spray system. At this time, the high-temperature indoor return air is cooled and sent into the room after heat exchange with the low-temperature and high-humidity outdoor air through the heat exchange core, and the low-temperature and high-humidity outdoor air is discharged into the outdoor environment after heat exchange with the high-temperature indoor return air through the heat exchange core; when the outdoor temperature further rises, natural heat exchange alone cannot meet the indoor temperature needs. Therefore, the supplementary cooling part is turned on while natural heat exchange is carried out to supplement the cooling capacity, so as to reach the required indoor temperature.

[0036] In the spray mode and the spray + supplementary cooling mode, since the outdoor air needs to be cooled by evaporating the spray water, the ion concentration of the circulating water in the spray water receiving tray will become higher and higher. Therefore, it is necessary to carry out sewage discharge treatment on the circulating water in the water receiving tray to keep the ion concentration of the circulating water in the water receiving tray lower than a certain value.

[0037] In order to ensure the normal operation of the spray system during sewage discharge (that is, to give priority to ensuring the refrigeration capacity of the device), the current conventional sewage discharge method is the dilution sewage discharge method, that is, when the ion concentration of the sewage in the water receiving tray reaches a certain concentration, a part of the sewage in the water receiving tray is drained, and then a part of new water is replenished. In this way, the ion concentration of the sewage in the water receiving tray will be diluted, but this sewage discharge method cannot make the ion concentration of the sewage in the water receiving tray reach a lower level, so the sewage discharge frequency will be higher and the sewage consumption will be higher.

[0038] Based on the above, the embodiments of the present application provide a sewage discharge control method, device, equipment and medium applied to the above-mentioned device with evaporative cooling function, which can ensure the refrigeration capacity of the device, reduce the sewage discharge frequency at the same time, and then reduce the sewage consumption, so as to achieve the purpose of water saving. The specific sewage discharge control method will be described in detail in the following embodiments.

[0039] In the first aspect, the embodiments of the present application provide a sewage discharge control method. Figure 2This is a schematic flowchart of a sewage control method in an embodiment of the present application. Please refer to Figure 2 In some embodiments, the sewage control method includes:

[0040] Step S110: Obtain the ambient temperature of the device with an evaporative cooling function.

[0041] Step S120: When the ambient temperature of the device with an evaporative cooling function is higher than the first preset temperature, control the sewage in the water receiving tray to be discharged in a first sewage discharge manner.

[0042] Step S130: When the ambient temperature of the device with an evaporative cooling function is lower than the first preset temperature, control the sewage in the water receiving tray to be discharged in a second sewage discharge manner according to preset conditions.

[0043] In some embodiments, the execution subject of the sewage control method may be a control device provided in a device with an evaporative cooling function. The control device may include a processor and a memory, and is used to control the various components of the device with an evaporative cooling function to work in coordination.

[0044] The device with an evaporative cooling function may include a temperature detection module provided outdoors, such as Figure 1 the outdoor temperature sensor shown in. The ambient temperature can be obtained through the temperature detection module. After obtaining the ambient temperature, it is judged whether the ambient temperature is higher than the first preset temperature. Optionally, the ambient temperature may be one of the outdoor dry bulb temperature (usually there must be), the outdoor wet bulb temperature (if any), the condensation temperature (if any), the condensation pressure (if any), the condensation temperature difference (if any), and the condensation pressure difference (if any).

[0045] When the ambient temperature is higher than the first preset temperature, control the sewage in the water receiving tray to be discharged in a first sewage discharge manner. The first sewage discharge manner may be a conventional dilution sewage discharge manner, that is, when the ambient temperature is high, the conventional dilution sewage discharge manner is still adopted, and the spraying system does not stop running to ensure the refrigeration capacity of the device.

[0046] When the ambient temperature is lower than the first preset temperature, control the sewage in the water receiving tray to be discharged in a second sewage discharge manner according to preset conditions. Among them, the preset conditions may be conditions for ensuring the refrigeration capacity of the device, and the second sewage discharge manner may be a sewage discharge manner with a lower sewage discharge frequency than the dilution sewage discharge, so as to reduce the sewage discharge frequency while ensuring the refrigeration capacity of the device, and further reduce the sewage consumption for discharge, achieving the purpose of water saving.

[0047] In addition, by judging whether the ambient temperature is higher than the first preset temperature in the embodiment of the present application, the sewage in the water receiving tray can be automatically controlled to be discharged in a first sewage discharge manner or a second sewage discharge manner, with a high degree of automation, no need for manual intervention, and saving labor costs.

[0048] In some embodiments, controlling the sewage in the water receiving tray to be discharged in a second sewage discharge manner includes:

[0049] Controlling the spray system to stop operating and controlling the sewage in the water receiving tray to be emptied.

[0050] That is, when the ambient temperature is relatively low, it can be considered to control the spray system to stop operating, and consider directly emptying the sewage and then replenishing with new water. The initial ion concentration in the water receiving tray after each sewage discharge cycle is as low as that of the replenished new water, so the entire sewage discharge cycle will be longer, that is, the sewage discharge frequency is low, and the sewage discharge volume per time is smaller than the diluted sewage discharge volume, thereby achieving the purpose of water conservation.

[0051] As described above, discharging sewage in the second sewage discharge manner will control the spray system to stop operating. To ensure the refrigeration capacity of the equipment, it is necessary to consider whether the equipment can meet the air supply temperature requirements after the spray system stops operating when discharging sewage by emptying. Therefore, in some embodiments, the preset conditions include that the indoor air supply temperature is lower than a second preset temperature. Specifically, the equipment with an evaporative cooling function may further include a temperature detection module provided at the indoor air supply location. When the ambient temperature is lower than the first preset temperature, the indoor air supply temperature can be obtained through the temperature detection module. After obtaining the indoor air supply temperature, it is judged 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 indicates that the refrigeration 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 manner, so as to reduce the sewage discharge frequency while ensuring the refrigeration capacity of the equipment, and further reduce the sewage consumption for discharge, achieving the purpose of water conservation.

[0052] It should be noted that multiple pieces of equipment with an evaporative cooling function may be installed in one room. If the spray system needs to stop operating when one of the equipment discharges sewage by emptying (i.e., the second sewage discharge manner), there will be a certain fluctuation in the common air supply temperature of the multiple pieces of equipment at this time. Therefore, in some embodiments, the preset conditions include that at least one adjacent piece of equipment is not discharging sewage. Specifically, before discharging sewage in the second sewage discharge manner, it can be first judged whether the adjacent equipment group of this equipment is discharging sewage, for example, judging whether the 4 adjacent pieces of equipment of this equipment (i.e., 2 pieces on the left and 2 pieces on the right) are discharging sewage. If at least one adjacent piece of equipment is not discharging sewage, that is, the spray systems of one or more adjacent pieces of equipment are operating normally, then this equipment can discharge sewage by emptying, preventing all the equipment in the same area from stopping spraying simultaneously, resulting in too high an indoor temperature.

[0053] It can be understood that the above embodiments take at least one adjacent piece of equipment not discharging sewage as the judgment criterion. In actual application scenarios, at least two or at least three adjacent pieces of equipment not discharging sewage can be used as the judgment criterion to prevent multiple pieces of equipment in the same area from stopping spraying simultaneously, thereby more effectively preventing the indoor temperature from being too high.

[0054] In some embodiments, the sewage discharge control method further includes:

[0055] If adjacent devices are all discharging sewage, wait until the adjacent devices finish discharging sewage and then discharge sewage in a second sewage discharge manner.

[0056] If adjacent devices are all performing emptying sewage discharge, that is, the spray systems of the adjacent devices have all stopped operating, then wait until other adjacent devices complete sewage discharge before discharging sewage, to prevent all devices in the same area from simultaneously stopping spraying, which may cause the indoor temperature to be too high.

[0057] It can also be understood that in the above embodiments, the judgment criterion is that adjacent devices are all discharging sewage. In actual application scenarios, the judgment criterion can be that a number of devices that is slightly less than the number of all adjacent devices are discharging sewage.

[0058] Figure 3 FIG. is a schematic flow chart of the sewage discharge control method in another embodiment of the present application. Please refer to Figure 3 , in some embodiments, before controlling the sewage in the water receiving tray to be discharged in a second sewage discharge manner, the sewage discharge control method further includes:

[0059] Step S140: Detect whether the compressor is turned on.

[0060] Step S150: If the compressor is not turned on, control the compressor to be turned on.

[0061] In some embodiments, in order to prevent the indoor air supply temperature of the device from being too high after the spray system stops operating, detect whether the compressor of the device is turned on before controlling the spray system to stop operating. If the compressor is not turned on, control the compressor to be turned on in advance, so that the compressor can quickly load after the spray system stops operating, respond to the change in the indoor air supply temperature of the device, and thus reduce the indoor air supply temperature.

[0062] In some embodiments, before discharging the sewage in the water receiving tray, the sewage discharge control method further includes:

[0063] Obtain the ion concentration of the sewage in the water receiving tray;

[0064] If the ion concentration is greater than or equal to a preset concentration, discharge the sewage in the water receiving tray.

[0065] An ion concentration detection module, such as an ion concentration detector, can be set 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, execute the steps of the sewage discharge control method in the above embodiments.

[0066] Second aspect: An embodiment of the present application further provides a sewage discharge control device, including a memory and a processor. The memory stores a computer program. When the computer program is executed by the processor, the processor performs the following steps: When the ambient temperature of the device with an evaporative cooling function is higher than the first preset temperature, control the sewage in the water receiving tray to be discharged in a first sewage discharge manner; when the ambient temperature of the device with an evaporative cooling function is lower than the first preset temperature, control the sewage in the water receiving tray to be discharged in a second sewage discharge manner according to preset conditions.

Please refer to Figure 4 , in some embodiments, the sewage discharge control device includes a processor, a memory, and a network interface connected through a system bus.
