A dehumidification device and a dehumidification method

Abstract

A dehumidification device comprises a shell body, a dehumidification radiator, a control device and a threshold value correcting device, wherein the radiator comprises cooling fins used for dissipating heat and condensing fins used for dehumidification and is used for refrigeration of the condensation fins and transmitting heat of the condensation fins to the cooling fins; the control device is used for detecting temperatures and humidity inside and outside of a box and the temperature of the cooling fins and is used for receiving detection signals of a detection device and carrying out corresponding data processing and control output; the threshold value correcting device is used for correcting a starting or stopping threshold value according to an inside and outside environment difference value. The dehumidification device is used for dehumidification operation inside a box body of an electric distribution box, semiconductor refrigeration dehumidification and full-electronic control are adopted, the starting threshold value can be automatically corrected according to the real working environment, dehumidification and heat dissipation effects can be reliable, and pollution does not exist. The invention further discloses a dehumidification method.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a dehumidification device used for dehumidification and drying inside an electric distribution box cabinet. Background technique [0002] The humidity in the air is as ubiquitous as the temperature. If the humidity in the room is too high, people will feel hot and uncomfortable. At the same time, when the relative humidity of the environment is greater than 60%, mold can grow. At the same time, equipment damage caused by moisture and mold to metal oxidation can occur unconsciously at any time. With the advancement of science and technology and the continuous improvement of product technology, its new production process and high requirements for environmental temperature, humidity and cleanliness in the production process, industrial dehumidifiers have begun to be widely used in large computer rooms, industrial workshop warehouses, file management , underground engineering and other impo...

AI Technical Summary

Problems solved by technology

[0003] Existing industrial dehumidifiers mostly adopt the principle of fluorine refrigeration, which is bulky and inconvenient to install in distribution cabinets; therefore, most of the existing dehumidification in distribution cabinets adopts the method of humidity controller + heater. Molecules are discharged out of the box, only to increase the temperature inside the box, so that the water vapor does not condense into dewdrops; because the air moisture in the box is in an unsaturated state, when the box is not well sealed, the water vapor outside the box will enter the box, resulting in dew in the box. When the absolute humidity rises, the dehumidification effect cannot be achieved when the temperature changes rapidly

[0004] When the working environment is relatively harsh, when the temperature and humidity inside the box is higher than the temperature and humidity of the external environment, the system will sense deviations and automatically stop the dehumidification and heat dissipation work, making the dehumidification device useless and unable to achieve the function of dehumidification and heat dissipation
