Background
At present, the problems of humidity, condensation and the like in an electric appliance box still exist in the field of air conditioning. The condensation is usually generated because most of traditional electrical boxes adopt air cooling to dissipate heat, the sealing effect of the shell is poor, and a large amount of water vapor is easily accumulated in the electrical boxes in a humid environment. Meanwhile, as the electric box is in a low-temperature environment, electric elements in the box continuously work to generate heat, and the temperature outside the shell is low, a large amount of water vapor in the electric box is condensed to form dew. The harm to the terminal box caused by the generation of condensation is mainly shown as follows: 1. devices with poor waterproof performance in the electrical box are easy to cause short circuit of a circuit due to condensation, and cannot work normally; 2. dew formed on some electrical equipment can corrode metal parts of the control equipment, affecting its useful life.

However, the water absorption effect is limited, the effect can be met only by periodic replacement, the maintenance cost is high, and the workload is large. For this reason, it is necessary to design a new solution to the problems of humidity and condensation of the electric cabinet.

Therefore, the refrigerating effect can be effectively ensured.
In order to further enhance the refrigerating effect, the condensation duct 1 of the present embodiment is in a shuttle shape; and the vertical direction of the fusiform condensation pipe can be bent at will, thereby increasing the condensation area and ensuring the refrigeration effect.
As another embodiment of the present utility model, unlike the above embodiment, the outer surface of the guide bracket 2 in this embodiment is provided with a water guide groove for guiding condensed water, and the water guide groove is connected to the condensation pipe 1 and is disposed at the bottom of the tank 1.

Namely, the refrigerating sheet used as a refrigerating source in the embodiment has a self-structure utilizing the peltier effect. The peltier effect refers to the phenomenon that when current passes through loops formed by different conductors, the joints of the different conductors can respectively absorb and release heat according to the current direction, and the heat absorption and release efficiency is in direct proportion to the current density passing through the conductors. Therefore, the heat absorption power of the refrigerating sheet can be controlled by controlling the magnitude of the current.

Therefore, the real-time monitoring of the temperature and humidity inside and outside the box body is realized, the control is convenient, and the condensation cannot occur inside the box body.
A control method of an anti-condensation device, comprising the steps of:
s1, acquiring temperature and humidity information;
the temperature and humidity information comprises an external temperature T1 of the box body, an internal temperature T2 of the box body, an internal humidity D2 of the box body, a device temperature T3 and the like.
Calculating a dew point temperature T0 when the temperature T2 in the box body is calculated according to the acquired humidity D2 in the box body; namely by the calculation formula: es= 6.112 ×exp ((17.67×t2)/(234.5+t2)), e= (es×d2)/100, t0= (243.5×log (E/6.112))/(17.67-log (E/6.112)), the dew point temperature T0 at the tank temperature T2 is calculated;
the dew point temperature: under the condition that the water vapor content in the air is constant and the air pressure is constant, the air reaches the temperature when the air is saturated.
S2, comparing the humidity in the box body;
s3, controlling the working state of the refrigeration assembly according to the comparison result.
Specifically, when the humidity in the box body is lower than a first humidity threshold value, condensation cannot be generated in the box body, and the refrigeration assembly stops working;
when the humidity in the box body is larger than or equal to a first humidity threshold value and smaller than a second humidity threshold value, selectively working of the refrigeration component is controlled according to the obtained device temperature T3;
when the humidity in the box body is greater than or equal to a second humidity threshold value, the refrigeration assembly is controlled to comprehensively work so as to enable the surface of the condensation assembly to generate condensed water.
The processor utilizes the data acquired in real time to generate a temperature and humidity curve through statistics, and makes a corresponding processing scheme according to comparison conditions according to the curve and threshold value in a certain time.
The scheme is as follows:
when the humidity inside the tank is lower than the first humidity threshold (D2 < K1). At this time, under normal conditions, no matter how the external temperature changes, the inside of the box body can not be condensed, and the refrigerating sheet stops working at this time.
When the internal humidity is greater than or equal to a first humidity threshold (D2 is greater than or equal to K1) and is less than a second humidity threshold (D2 is less than K2), the refrigerating sheet selectively works;
at this time, the system starts to collect the data in the box body, and the temperature required by condensation at this time can be known according to the data and the pre-stored enthalpy-humidity diagram, and the dew point temperature in the box body and the refrigerating power of the refrigerating sheets at this time are determined. Specifically, the device with the temperature close to the dew point temperature is found out by monitoring the temperature T3 of the device in the box body and comparing the dew point temperature, so that condensation is easy to generate, and the condensation sheet in the responsible area is controlled. The condensation collecting device is refrigerated, so that the temperature of the gas of the corresponding device accessory is reduced, the temperature is kept below T0, the temperature of the air in the box body can not reach the dew point temperature, and condensation can not be generated on the surface of the device.
When the humidity in the box body is larger than or equal to a second humidity threshold value (D2 is larger than or equal to K2), the temperature of the dew point in the box body and the refrigerating power of the refrigerating sheets are determined according to the collected data, and all the refrigerating sheets start to work, so that the air near the condensing device is far lower than the dew point temperature. Because the condensing assembly surface temperature is much lower than the device surface temperature, water vapor will preferentially condense into water at the condensing assembly. Thus, the condensation assembly surface begins to rapidly generate condensate water and the humidity within the tank rapidly decreases. After the water is led out through the water guide groove, the anti-condensation scheme is readjusted after the humidity inside the box body is detected in real time until the humidity is reduced to a second threshold value.
Note that: the first and second humidity thresholds are based on the local air temperature of the device, the first threshold is the condensation humidity generated by the box body when the air temperature is the lowest, and the second threshold is the condensation humidity generated by the box body when the air temperature is the highest.
An air conditioner comprises the anti-condensation device. According to the air conditioner disclosed by the utility model, the refrigerating assembly and the condensing assembly are combined with the electric box, the temperature of the inside and the outside of the box body, the temperature of the device and the humidity of the inside of the box body are monitored in real time, data are collected, the data are processed by the control assembly, and the temperature and the humidity of the inside of the box body are reduced in a specific control mode, so that the temperature of air in the box body cannot reach the dew point temperature, condensation is prevented, and the effects of dehumidification and condensation prevention are achieved.
