Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an anti-condensation device and a control method thereof, and an air conditioner. Background Art

[0002] Currently, air conditioning still faces issues such as moisture and condensation inside electrical enclosures. This condensation is typically caused by the fact that most traditional electrical enclosures utilize air cooling, and the enclosure itself is poorly sealed. In humid environments, large amounts of water vapor easily accumulate inside the enclosure. Furthermore, because the enclosure is located in a relatively low temperature environment, the electrical components within the enclosure continuously operate, generating heat, while the external temperature of the enclosure is relatively low, causing large amounts of water vapor to condense and form dew. The main hazards of condensation to terminal boxes are: 1. Condensation can cause short circuits in poorly waterproof components within the enclosure, preventing them from functioning properly; 2. Dew formed on some electrical equipment can corrode the metal components of the control equipment, shortening its service life.

[0003] Currently, there are several common methods for addressing moisture and condensation. One approach involves using electric heaters to heat the electrical enclosure and equipment to prevent condensation. However, this method only temporarily prevents condensation inside the enclosure, and high humidity inside the enclosure can also affect components. Another approach involves using desiccants, which are absorbent materials added to the enclosure to absorb moisture and reduce humidity, thereby preventing condensation. However, these desiccants are only effective in absorbing moisture and require regular replacement to maintain adequate results, resulting in high maintenance costs and workload. Therefore, a new solution is needed to address moisture and condensation issues in electrical control boxes. Summary of the Invention

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] like Figure 1-Figure 3 As shown, the present invention provides an anti-condensation device, including a box body 100, on which a condensation component 200, a temperature and humidity monitoring component, and a control component are installed. A refrigeration component is installed on the condensation component 200, and the control component is electrically connected to the refrigeration component and the temperature and humidity monitoring component, and is used to control the working state of the refrigeration component according to the temperature and humidity information obtained by the temperature and humidity monitoring component, so that the air temperature inside the box cannot reach the dew point temperature, thereby preventing condensation and achieving the effect of dehumidification and anti-condensation.

[0038] In this embodiment, the condensing assembly 200 includes a condensing tube 1, a guide bracket 2 is mounted on the condensing tube 1, and a heat conducting plate 3 is mounted on the other end of the guide bracket 2. The condensing assembly 200 is fixedly connected to the housing 100 via the heat conducting plate 3. This facilitates cooling the air inside the housing.

[0039] As another embodiment of the present invention, different from the above embodiment, the condenser tube 1 and the flow guide bracket 2 in this embodiment are hollow, and the hollow condenser tube 1 and the flow guide bracket 2 are filled with condensate, thereby effectively ensuring the cooling effect.

[0040] In order to further enhance the cooling effect, the condenser tube 1 of this embodiment is in a spindle shape; and the vertical direction of the spindle-shaped condenser tube can be bent arbitrarily, thereby increasing the condensation area and ensuring the cooling effect.

[0041] As another embodiment of the present invention, different from the above embodiment, the outer surface of the diversion bracket 2 in this embodiment is provided with a water guide groove for guiding condensed water. The water guide groove is connected to the condenser pipe 1 and is arranged at the bottom of the housing 1. This facilitates the diversion of condensed water from the condenser pipe out of the housing, preventing short circuits in the components inside the housing.

[0042] As another embodiment of the present invention, different from the above embodiment, the heat conducting plate 3 in this embodiment is tightly attached to the refrigeration component via heat dissipation silicone grease. The heat conducting plate is a heat-conducting graphene sheet, which can enhance heat transfer between the refrigeration component and the condensing component.

[0043] As another embodiment of the present invention, different from the above embodiment, the refrigeration assembly in this embodiment includes a refrigeration fin 300, and a first fixed steel plate 401 and a second fixed steel plate 402 are provided on both sides of the refrigeration fin 300. The first fixed steel plate 401 is provided with a heat sink 6, and the second fixed steel plate 402 is connected to the heat conduction plate 3.

[0044] As another embodiment of the present invention, unlike the above embodiment, the cooling fin 300 in this embodiment includes a cooling plate 5, with a first copper plate 701 disposed at the lower end of the cooling plate 5. The lower ends of the first copper plate 701 are connected to a P-pole semiconductor 9 and an N-pole semiconductor 10. The lower end of the P-pole semiconductor 9 is connected to a second copper plate 702, and the lower end of the N-pole semiconductor 10 is connected to a third copper plate 703. The lower ends of the second and third copper plates 702 and 703 are connected to an insulating plate 8, which is made of insulating ceramic. The P-pole semiconductor 9 and the N-pole semiconductor 10 are arranged in parallel. Thus, the Peltier effect is utilized to control the heat absorption power of the cooling fin by controlling the magnitude of the current.

[0045] In other words, the cooling plate used as the cooling source in this embodiment utilizes the Peltier effect. The Peltier effect refers to the phenomenon that when current flows through a loop composed of different conductors, the joints of the conductors absorb and release heat depending on the direction of the current flow. The efficiency of heat absorption and release is proportional to the current density passing through the conductors. Therefore, the heat absorption power of the cooling plate can be controlled by controlling the current.

[0046] As another embodiment of the present invention, unlike the above embodiment, the temperature and humidity monitoring assembly in this embodiment includes one or more of an external ambient temperature sensor, a box temperature sensor, an indoor humidity sensor, a device temperature sensor, and an internal pressure sensor. This enables real-time monitoring of the temperature and humidity inside and outside the box, facilitating control to prevent condensation inside the box.

[0047] A method for controlling an anti-condensation device comprises the following steps:

[0048] S1. Obtain temperature and humidity information;

[0049] The temperature and humidity information includes the external temperature T1 of the box, the internal temperature T2 of the box, the internal humidity D2 of the box, the device temperature T3, etc.

[0050] Calculate the dew point temperature T0 when calculating the internal temperature T2 of the box based on the obtained internal humidity D2 of the box; that is, through 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)), calculate the dew point temperature T0 when the box temperature T2 is obtained;

[0051] This dew point temperature: Under the condition that the water vapor content in the air is certain and the air pressure is certain, the temperature when the air reaches saturation.

[0052] S2. Compare the internal humidity of the box;

[0053] S3. Control the working state of the refrigeration component according to the comparison result.

[0054] Specifically, when the internal humidity of the box is lower than the first humidity threshold, no condensation will occur inside the box, and the refrigeration component stops working;

[0055] When the internal humidity of the box is greater than or equal to the first humidity threshold and less than the second humidity threshold, control the refrigeration component to work selectively according to the obtained device temperature T3;

[0056] When the internal humidity of the box is greater than or equal to the second humidity threshold, control the refrigeration component to work comprehensively so that condensate water is generated on the surface of the condensation component.

[0057] That is, the processor uses the real-time collected data to statistically generate a temperature-humidity curve, and based on the comparison of the curve with the threshold within a certain period of time, make a corresponding processing plan according to the comparison situation.

[0058] The specific plan is as follows:

[0059] When the internal humidity of the box is lower than the first humidity threshold (D2 < K1). Under normal circumstances at this time, no matter how the external temperature changes, no condensation will occur inside the box, and the thermoelectric cooler stops working at this time.

[0060] When the internal humidity is greater than or equal to the first humidity threshold (D2 ≥ K1) and less than the second humidity threshold (D2 < K2), the thermoelectric cooler works selectively;

[0061] At this point, the system begins collecting data from inside the cabinet. By comparing this data with a pre-stored psychrometric chart, it determines the temperature required for condensation to occur, the dew point inside the cabinet, and the cooling power of the refrigeration plate. Specifically, by monitoring the temperature T3 of the components inside the cabinet and comparing it to the dew point, it identifies components with temperatures close to those that are prone to condensation and controls the condensation plates in their respective areas. By cooling the condensation collection device, the air around the corresponding components is cooled, keeping the temperature below T0. At this point, the air temperature inside the cabinet does not reach the dew point, and condensation cannot form on the component surfaces.

[0062] When the humidity inside the cabinet is greater than or equal to the second humidity threshold (D2 ≥ K2), the humidity inside the cabinet is relatively high. Based on the collected data, the dew point temperature inside the cabinet and the cooling power of the refrigeration plate are determined. All refrigeration plates start working, making the air near the condensing device much lower than the dew point temperature. Because the surface temperature of the condensing component is much lower than the surface temperature of the device, water vapor will preferentially condense into water in the condensing component. Therefore, condensed water begins to form rapidly on the surface of the condensing component, and the humidity inside the cabinet drops rapidly. After the water is drained out through the water guide groove, the humidity inside the cabinet is detected in real time until it drops to the second threshold, and then the anti-condensation plan is readjusted.

[0063] Note: The first and second humidity thresholds are based on the local temperature where the device is installed. The first threshold is the humidity at which condensation occurs in the cabinet at the lowest temperature, and the second threshold is the humidity at which condensation occurs in the cabinet at the highest temperature.

[0064] An air conditioner includes the aforementioned anti-condensation device. The air conditioner of the present invention combines a refrigeration component and a condensing component with an electrical box, and monitors the internal and external temperatures, device temperatures, and humidity of the cabinet in real time. The collected data is then processed by a control component, and the internal temperature and humidity of the cabinet are lowered through a specific control method, preventing the air temperature inside the cabinet from reaching the dew point, thereby preventing condensation and achieving both dehumidification and anti-condensation effects.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
