Detailed introduction

Product overview

The HKCS series intelligent dehumidification device adopts a semiconductor refrigeration dehumidification method, which actively sucks the humid air in the confined space into the dehumidification air duct under the action of a fan. The water vapor in the air is condensed into water after passing through the semiconductor refrigeration mechanism, and then discharged through the water pipe. The cabinet body can achieve a good dehumidification effect. By reducing the water content in the air, the relative humidity and absolute humidity drop at the same time, almost no increase in temperature, no negative impact caused by temperature difference, fundamentally eliminate or reduce the occurrence of accidents, and will not accelerate the aging of components and cabinets in the cabinet due to high temperature. The intelligent dehumidification device changes the passive condensation prevention method to active condensation guidance, which effectively prevents potential safety hazards such as aging of equipment in the cabinet, reduction of insulation strength, breakdown of secondary terminals, material mildew and corrosion of steel structures, and ensures the safe operation of the power grid.

Working principle

HKCS series intelligent dehumidification device consists of power supply system, air supply system, semiconductor refrigerator, temperature and humidity detection control circuit, heating circuit, wireless module and drainage pipeline.

1. Dehumidification principle

When the humid air is sucked in by the fan, it flows through the specially designed air duct, first passes through the semiconductor refrigerator for cooling and condensation, and the condensation of the refrigerator drips into the water inlet under the action of gravity, and then flows out of the cabinet through the water guide pipe. After sufficient circulation dehumidification within the set starting value, the air humidity in the cabinet is reduced to below the dew point, and the whole moisture-proof condensation-inducing heating process is completed. At the same time, the signal acquisition sensor of the intelligent dehumidification device is external, which can accurately collect the real humidity in the cabinet in real time, and ensure that the intelligent dehumidification device starts dehumidification in advance when the condensation condition is about to be reached in the cabinet.

2. Low temperature heating function

When the box temperature is lower than the set starting value, the dehumidifying device starts the internal heater circuit (the heater is externally connected, and the power can be connected to 50~500W), until the box temperature rises to the set starting value plus 5 ° c, the heater circuit stops working.

3. RS485 communication function

When the dehumidification device with RS485 communication function receives the data from the upper computer, it will immediately reply the data to the upper computer after analyzing the data. One upper computer can be connected to a maximum of 200 units (the upper computer end is recommend a 120 ohm load resistor between A and B).
