Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification equipment, and in particular to a cabinet dehumidification device and a dehumidification method. Background Art

[0002] As a key power transmission and distribution node, the stable operation of the power distribution cabinet is crucial to ensure the continuity and reliability of power supply. However, the unique coastal environment, high humidity, salt spray, sea breeze erosion and other harsh conditions pose a severe challenge to the electronic equipment inside the power distribution cabinet. In particular, the humidity problem, too high humidity will not only lead to the decline of equipment insulation performance, but also may cause short circuit, corrosion and other faults, seriously affecting the normal operation and service life of the power distribution cabinet.

[0003] Dehumidifiers, also known as dehumidifiers, dryers or dehumidifiers, are mainly divided into two categories: civil dehumidifiers and industrial dehumidifiers. Civil dehumidifiers are mainly used in home and office environments. They are small in size, low in power, and have relatively small dehumidification capacity; while industrial dehumidifiers are used in factories, warehouses and other places that require large-area dehumidification. They have large dehumidification capacity and durability. With the advancement of science and technology, the types and technologies of dehumidifiers are constantly updated, and there are many types of dehumidifiers, such as condensing dehumidifiers, adsorption dehumidifiers, and compression dehumidifiers. Each type of dehumidifier has its unique working principle and applicable scenarios.

[0004] The basic working principle of a cabinet dehumidifier is to prevent electronic components from getting damp by reducing the relative humidity of the air inside the cabinet. Usually, a cabinet dehumidifier uses a PTC (Positive Temperature Coefficient) refrigeration sheet. Through its moisture absorption and cooling functions, the water vapor in the air is condensed into water droplets, thereby achieving dehumidification. The condensed water is discharged out of the cabinet through the water pipe to ensure that the inside of the cabinet always remains dry. The cabinet dehumidification equipment in the prior art has some defects, such as a single air duct structure and high noise. The air duct design of traditional dehumidifiers is often relatively simple and lacks optimization for the high humidity environment at the seaside, resulting in low air circulation efficiency, limited dehumidification effect, insufficient air circulation inside the cabinet, and difficulty in quickly and effectively reducing the overall humidity.

[0005] In summary, in response to the dehumidification needs of coastal power distribution cabinets, the research and development of cabinet dehumidifiers with efficient air circulation and quietness has become an important direction in the current technical field. Summary of the invention

[0006] The object of the present invention is to provide a cabinet dehumidification device and method to solve the above-mentioned deficiencies in the technology.

[0026] Shutdown and standby: When the humidity inside the cabinet reaches or is lower than the target value, the dehumidifier automatically enters standby mode to reduce energy consumption; if dehumidification is not needed for a long time, it can be set to automatically shut down.

[0040] The top outer wall of the PTC refrigeration sheet 9 is fixed with a heat dissipation fin 10, and a fixing opening is opened on one side of the top of the fixed shell 3. Two heat dissipation fans 11 are fixed on the top outer wall of the heat dissipation fin 10. The heat dissipation fans 11 are silent fans.

[0042] Working principle of the present invention:

[0043] Refer to the instruction manual Figure 1-5 When in use, the present invention is installed inside the cabinet, and a water guide hose is used to connect the drain pipe joint 12 provided at the bottom of the water receiving box 1, and then a power line is used to connect the power connection module 13.

[0044] Embodiment 2 of the present invention discloses a dehumidification method for a cabinet dehumidification device, which specifically includes the following steps:

[0045] Step 1, initialization: After power-on, the dehumidifier performs system self-check (the target parameters come from the remote communication settings. If the current communication is lost, the parameters of the last operation are enabled);

[0046] Step 2, environmental detection: detect the current humidity and temperature inside the cabinet, and detect the humidity at the end of the air duct. Analyze the data to determine whether to start the dehumidification operation / whether to adjust the fan speed;

[0047] Step 3, wind speed control: Automatically select or adjust the fan speed based on the difference between the current humidity and the target humidity, and the preset humidity control strategy. If the humidity is much higher than the target value, high speed operation is selected; as the humidity approaches the target value, the wind speed is gradually reduced;

[0048] Step 4, dehumidification operation: Start the fan and energize the PTC to start the dehumidification operation. Monitor the humidity at the dehumidification outlet in real time, and keep the outlet humidity at a low level by adjusting the compressor working intensity or fan speed;

[0049] Step 5, intelligent control: dynamically adjust the working mode (such as continuous dehumidification, intermittent dehumidification, energy-saving mode, etc.) according to the dehumidification effect and environmental changes;

[0050] Step 6, Fault detection and alarm: Real-time monitoring of the operating status of each component. Once a fault is found (such as sensor failure, PTC overheating, etc.), the dehumidification operation is immediately stopped and an alarm is issued through communication. The fault information is recorded and sent to the cloud system;

[0051] Step 7, shutdown and standby: When the humidity inside the cabinet reaches or is lower than the target value, the dehumidifier automatically enters standby mode to reduce energy consumption. If dehumidification is not needed for a long time, the automatic shutdown function can be set.
