Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of an anti-condensation method for a control cabinet according to an embodiment of the present invention, where the anti-condensation method includes:

step S11: acquiring a humidity value in a target control cabinet;

wherein, a heater and a water cooler are arranged in the target control cabinet;

step S12: if the humidity value in the cabinet is smaller than or equal to the preset humidity value, controlling the heater and the water cooler to be in a standby mode;

step S13: and if the humidity value in the cabinet is greater than the preset humidity value, acquiring a humidity difference value A between the humidity value in the cabinet and the preset humidity value, and regulating and controlling the working states of the heater and the water cooler according to the humidity difference value A so as to discharge condensed water generated on the outer wall of the water cooler to the outside of the target control cabinet, thereby reducing the humidity value in the cabinet to the preset humidity value or inhibiting the formation of the condensed water in the target control cabinet.

In this embodiment, a method for preventing condensation in a control cabinet is provided, by which condensed water in the control cabinet can be removed and the amount of power consumption required by the control cabinet can be reduced. In this condensation prevention method, a heater and a water cooler need to be added in advance in the target control cabinet.

After the heater and the water cooler are added in the target control cabinet, firstly, the humidity value in the target control cabinet is obtained, wherein the humidity value in the target control cabinet can be obtained through the sensor. And when the humidity value in the target control cabinet is obtained, comparing the humidity value in the target control cabinet with a preset humidity value.

It can be understood that whether the condensed water can be formed in the target control cabinet is closely related to the in-cabinet humidity value of the target control cabinet, so that whether the condensed water can be formed in the target control cabinet can be judged by comparing the in-cabinet humidity value of the target control cabinet with the preset humidity value.

Specifically, if the humidity value in the target control cabinet is smaller than or equal to the preset humidity value, it indicates that the target control cabinet is dry, and no condensed water is formed, and at this time, the heater and the water cooler in the target control cabinet can be controlled to be in the standby mode, so that the power consumption required by the target control cabinet is reduced. If the humidity value in the target control cabinet is larger than the preset humidity value, the fact that the target control cabinet is relatively humid is indicated, and condensate water can be generated.

Compared with the prior art that no condensed water is ensured to be in the control cabinet only when the heater in the control cabinet is in the running state all the time, the method provided by the embodiment can avoid the heater in the control cabinet from being in the running state all the time, so that the energy consumption required by the control cabinet can be obviously reduced by the method. In addition, because the method can avoid the generation of condensed water in the control cabinet, the safe and stable operation of the target control cabinet can be ensured by the method.

It can be seen that, in this embodiment, a heater and a water cooler are arranged in the target control cabinet in advance, and if the humidity value in the target control cabinet is less than or equal to the preset humidity value, the heater and the water cooler in the target control cabinet are both controlled to be in the standby mode; and if the humidity value in the target control cabinet is larger than the preset humidity value, acquiring a humidity difference value A between the humidity value in the target control cabinet and the preset humidity value, and regulating and controlling the working states of a heater and a water cooler in the target control cabinet according to the humidity difference value A so as to discharge condensed water generated by the outer wall of the water cooler to the outside of the target control cabinet, thereby reducing the humidity value in the target control cabinet to the preset humidity value or inhibiting the formation of the condensed water in the target control cabinet. Obviously, compared with the prior art that the heater in the control cabinet is always in the running state to ensure that no condensed water exists in the control cabinet, the arrangement mode can reduce the power consumption required by the control cabinet while removing the condensed water in the control cabinet.

Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, and as a preferred implementation, the preset humidity value is set according to the specification standard of the target control cabinet.

It can be understood that, because the standard of the target control cabinet is a criterion that can ensure the target control cabinet to safely operate, when the preset humidity value is set according to the standard of the target control cabinet, not only the accuracy of the preset humidity value can be ensured, but also the overall reliability of the target control cabinet in the operation process can be ensured.

In addition, in practical application, the preset humidity value can be adaptively adjusted according to the actual operation condition of the target control cabinet and the influence of external environmental factors, so that the set value of the preset humidity value better conforms to the actual operation condition of the target control cabinet, and specific details are not repeated here.

Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, please refer to fig. 2, and fig. 2 is a flowchart for regulating and controlling the working states of the heater and the water cooler in the target control cabinet according to the embodiment of the present invention. As a preferred embodiment, the above steps: the process of regulating and controlling the working states of the heater and the water cooler according to the humidity difference A comprises the following steps:

step S301: if the humidity value in the cabinet is greater than or equal to 110% of the preset humidity value, controlling the heater and the water cooler to be in a normal operation mode;

in this embodiment, an actual operation method for regulating and controlling the working states of the heater and the water cooler in the target control cabinet is provided. Specifically, when the humidity value in the target control cabinet is greater than or equal to 110% of the preset humidity value, it is indicated that the humidity value in the target control cabinet is high, and condensed water is generated in the target control cabinet, and under this condition, it is required to control both the heater and the water cooler in the target control cabinet to be in a normal operation mode to ensure that the condensed water does not appear in the target control cabinet. Namely, the condensed water of the target control cabinet is vaporized and evaporated through the normal operation of the heater, and when the condensed water is generated on the outer wall of the water cooler, the condensed water in the target control cabinet is discharged out of the target control cabinet by using the water cooler.

Step S302: if the humidity value in the cabinet is less than 110% of the preset humidity value, acquiring the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet;

step S303: if the temperature B in the cabinet is higher than the temperature C outside the cabinet, controlling the water cooler to work and the heater to stand by;

step S304: if the cabinet internal temperature B is less than or equal to the cabinet external temperature C, acquiring a temperature difference D between the cabinet internal temperature B and the cabinet external temperature C;

step S305: if the temperature difference D is smaller than or equal to the preset temperature difference M, controlling one of the water cooler and the heater to work, and enabling the other one to stand by;

step S306: and if the temperature difference D is larger than the preset temperature difference M, controlling the heater and the water cooler to be in a normal operation mode.

When the humidity value in the target control cabinet is less than 110% of the preset humidity value, it is determined that the humidity value in the target control cabinet exceeds the standard, and in this case, the operation states of the heater and the water cooler in the target control cabinet need to be regulated according to the temperature difference D between the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet.

Specifically, when the humidity value in the target control cabinet is less than 110% of the preset humidity value, the temperature B in the target control cabinet and the temperature C outside the target control cabinet can be obtained by using the sensors arranged inside and outside the target control cabinet. If the cabinet internal temperature B of the target control cabinet is higher than the cabinet external temperature C of the target control cabinet, the target control cabinet can transmit heat to the external environment, and condensate water can be generated in the target control cabinet.

If the cabinet internal temperature B of the target control cabinet is less than or equal to the cabinet external temperature C of the target control cabinet, it indicates that the external environment can transmit heat to the target control cabinet, and under the condition, the working states of the heater and the water cooler in the target control cabinet need to be specifically determined according to the temperature difference D between the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet.

Specifically, when the cabinet internal temperature B of the target control cabinet is less than or equal to the cabinet external temperature C of the target control cabinet, a temperature difference D between the cabinet internal temperature B of the target control cabinet and the cabinet external temperature C needs to be calculated, and if the temperature difference D is less than or equal to a preset temperature difference M, it indicates that no particularly significant heat transfer is performed between the target control cabinet and the external environment. In a preferred embodiment, the water cooler in the target control cabinet can be set to be in an operating state, and the heater of the target control cabinet can be set to be in a standby state.

If the temperature difference D between the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet is greater than the preset temperature difference M, the target control cabinet and the external environment can perform obvious heat transfer, in this case, condensed water can be generated in the target control cabinet, and at the moment, in order to ensure the safe and stable operation of the target control cabinet, a heater and a water cooler in the target control cabinet are required to be controlled to be in a normal operation mode to avoid the generation of the condensed water in the target control cabinet.

Obviously, the technical scheme provided by the embodiment can be used for more accurately regulating and controlling the target control cabinet.

In a preferred embodiment, the predetermined temperature difference M is 5 ℃.

Specifically, the preset temperature difference M can be set to 5 ℃, and since a large amount of experimental data show that when the temperature inside the target control cabinet is within 5 ℃ of the temperature outside the target control cabinet, no particularly significant heat transfer is performed between the target control cabinet and the external environment, and no condensed water is generated inside the target control cabinet, the accuracy in regulating and controlling the heater and the water cooler inside the target control cabinet can be further improved when the preset temperature difference M is set to 5 ℃.

That is, if the temperature difference D between the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet is within 5 ℃, it indicates that the heat transfer between the target control cabinet and the external environment is not obvious, and at this time, the heater and the water cooler in the target control cabinet can still select one to work normally, and the other is in a standby mode; if the temperature difference D between the cabinet internal temperature B and the cabinet external temperature C of the target control cabinet is more than 5 ℃, the target control cabinet can carry out stronger heat transfer with the external environment and can generate condensed water in the target control cabinet, and at the moment, in order to ensure the safe operation of the target control cabinet, a heater and a water cooler in the target control cabinet are required to be controlled to be in a normal operation state.

Such as: if the outside temperature of the target control cabinet is 30 ℃ and the inside temperature of the target control cabinet is 30-35 ℃, the heater in the target control cabinet only needs to be kept in a standby mode, and the water cooler is in a normal working state, so that no condensed water exists in the target control cabinet; if the outside temperature of the target control cabinet is 30 ℃ and the inside temperature of the target control cabinet is above 35 ℃, the heater and the water cooler in the target control cabinet are controlled to be in a normal operation mode to ensure that no condensed water is generated in the target control cabinet and ensure the safe and stable operation of the target control cabinet.

As a preferred embodiment, the above-mentioned condensation preventing method further comprises:

the heater and the water cooler work normally at the same time, so that when the humidity value in the cabinet is reduced to a preset humidity value, the heater is controlled to stop running firstly, and then the water cooler is controlled to stop running after a preset time.

In the regulation and control process of the heater and the water cooler in the target control cabinet, when the heater and the water cooler in the target control cabinet are in a normal operation state at the same time, after a period of operation time of the heater and the water cooler, the humidity value in the target control cabinet is reduced to a preset humidity value.

In this case, in order to discharge more condensed water in the target control cabinet to the outside of the target control cabinet, the heater may be controlled to stop operating, and then the water cooler may be controlled to stop operating after a preset time. Therefore, the humidity in the target control cabinet can be continuously reduced by utilizing the waste heat generated after the operation of the heater in the target control cabinet is stopped. Obviously, through the arrangement mode, more condensed water in the target control cabinet can be discharged out of the target control cabinet, and the aim of cooling the target control cabinet can be achieved. Specifically, in practical application, the preset time may be set to 1 min.

Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, and as a preferred implementation, the water cooler is disposed at the top of the target control cabinet.

Specifically, in this embodiment, set up the top at the target control cabinet with the water cooler, because when producing the comdenstion water in the target control cabinet, the comdenstion water is mostly formed by the vapor condensation in the target control cabinet, and vapor can be diffused to the top of target control cabinet at the in-process of evaporation, so, when setting up the water cooler at the top of target control cabinet, just can be comparatively fast with the vapor condensation in the target control cabinet for the comdenstion water to discharge the comdenstion water outside the target control cabinet.

Obviously, the technical scheme provided by the embodiment can relatively improve the condensation speed and efficiency of the condensed water.

As a preferred embodiment, the bottom of the water cooler is provided with a water collecting tank and a water outlet pipe for collecting condensed water, a water inlet of the water outlet pipe is communicated with the water collecting tank, a water outlet of the water outlet pipe is communicated with the outside of the target control cabinet, and the height of the water inlet of the water outlet pipe is higher than that of the water outlet pipe.

In this embodiment, in order to discharge the condensed water in the target control cabinet out of the target control cabinet more quickly, a water collecting tank and a water outlet pipe for collecting the condensed water are arranged at the bottom of the water cooler, wherein a water inlet of the water outlet pipe is communicated with the water collecting tank, a water outlet of the water outlet pipe is communicated with the outside of the target control cabinet, and a water inlet of the water outlet pipe is higher than a water outlet of the water outlet pipe. Obviously, by adopting the arrangement mode, the condensed water can be smoothly discharged out of the target control cabinet by utilizing the self-gravity of the condensed water.

As a preferred embodiment, the outlet pipe is embodied as a PPR pipe.

Specifically, in practical application, can set up the outlet pipe into PPR pipe, because PPR pipe not only has the characteristics of the health nonhazardous, moreover, PPR pipe still has high pressure resistant and high temperature resistant advantage, so, when setting up the outlet pipe into PPR pipe, just can prolong the life of outlet pipe relatively.

and the second controller 23 is configured to, if the humidity value in the cabinet is greater than the preset humidity value, obtain a humidity difference a between the humidity value in the cabinet and the preset humidity value, and regulate and control the operating states of the heater and the water cooler according to the humidity difference a, so that condensed water generated on the outer wall of the water cooler is discharged outside the target control cabinet, thereby reducing the humidity value in the cabinet to the preset humidity value, or suppressing formation of condensed water in the target control cabinet.

The anti-condensation device of the control cabinet has the beneficial effects of the anti-condensation method of the control cabinet.
