Above-mentioned new digital formula dehumidifier, energy Real-time and Dynamic Detection and display environment relative humidity, include automatic control logic, when reaching the startup setup parameter, relative humidity starts dehumidifying, when the semiconductor refrigerating assembly passes through certain DC current, because paltie effect, one end (cold junction) temperature reduces and the absorption heat, the other end (hot junction) temperature raises and emits heat, the whole cooling of cold junction and dehumidification heat exchange is also lowered the temperature when hot and humid gas is flowed through the dehumidification heat exchange internal pipeline, causes moisture content wherein to condense into water droplet, be discharged into the casing outside by conduit then, thereby reach the purpose of dehumidifying; When dropping to, relative humidity stops dehumidifying when stopping setup parameter.

Further, above-mentioned new digital formula dehumidifier can be realized manual original state selection, presses manipulated key and enters the hand-operated forced wet condition that removes, and presses manipulated key once more, then withdraws from the hand-operated forced wet condition that removes, and gets back to automatic dehumidifying monitor state.

Further, above-mentioned new digital formula dehumidifier can carry out self-operating monitoring and protection, when environment temperature that sensor fault, fan inside fault and Temperature Humidity Sensor collect occurring and be higher than situations such as setting value, send sound and light alarm, the action of warning contact, output alarm signal; And the situation that can be squeezed or tilt install this new digital formula dehumidifier, send sound and light alarm, stop dehumidifying, effectively protect the internal circuit of this new digital formula dehumidifier.

The utility model is compared with traditional hot type dehydrating unit, has the following advantages:

● simple in structure, heat evenly, but without any need for the cold-producing medium continuous operation;

● cost is low, the life-span is long, course of work friction, low noise, easy to use;

● can set operating parameter values according to actual needs flexibly;

● effect on moisture extraction is fast, only needs tens of seconds can separate out water droplet at high humidity environment;

● the dehumidification rate height, when reducing absolute humidity, utilize the circuit temperature rise further to reduce relative humidity;

● low energy consumption, environmental protection, 30W power is equivalent to the above heating and dehumidification device of 300W;

● totally digitilized high speed acquisition in-cabinet temperature and humidity, and show and control;

● do not produce overheated surface temperature, the traditional heating dehydrating unit is because surface temperature is too high, and is sometimes that the electric elements or the cable of periphery is roasting bad, and the employing of this device is condensation technology, the hot end surface temperature is lower than 50 degrees centigrade, can not have a negative impact to peripheral electric elements and cable.

The utility model is fully integrated integrated design; adopting cryogenic refrigeration sheet condensation technology, is hard core control control with the single-chip microcomputer intelligence control circuit, can fundamentally effectively reduce relative humidity; solve the hidden danger that the condensation phenomenon is brought, equipment and circuit in the cabinet of protection power distribution cabinet, switch cubicle etc.
