Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
This electric-controlled box low temperature dehumidification device, it comprises electric-controlled box 1, mainboard 2, temperature sensor 4, humidity sensor 5, exhaust blower 6 and air compressor 7, mainboard 2 is had at electric-controlled box 1 internal fixtion, temperature sensor 4 and humidity sensor 5, the sidewall of electric-controlled box 1 is provided with exhaust blower 6, air compressor 7 is provided with in the outside of electric-controlled box 1, the outlet side of air compressor 7 is connected with the supervisor 8 that gives vent to anger, the supervisor 8 that gives vent to anger is positioned at after electric-controlled box 1, be parallel with out gas branch pipe 9 giving vent to anger on supervisor 8, the stage casing going out gas branch pipe 9 is positioned at electric-controlled box 1, going out on gas branch pipe 9 outside electric-controlled box 1 is provided with check valve 10 and magnetic valve 11, check valve 10 is near the outlet side going out gas branch pipe 9, magnetic valve 11 is near the inlet end of gas branch pipe 9, and described temperature sensor 4, humidity sensor 5, exhaust blower 6, air compressor 7, magnetic valve 11 are all connected by circuit with mainboard 2.
In described electric-controlled box 1, be provided with electric heating sheets 3, electric heating sheets 3 is connected by circuit with mainboard 2.
Integrated Intelligent dehumidifying devices such as the present invention's magnetic valve 11, check valve 10, exhaust blower 6, air compressor 7, temperature sensor 4, humidity sensor 5 and mainboard 2.Reach dehumidifying condition, by the temperature and humidity data that temperature sensor 4, humidity sensor 5 gather, feed back on mainboard 2, Based Intelligent Control magnetic valve 11, exhaust blower 6 is opened, utilize air compressor 7 to work to give vent to anger the high temperature of supervisor 8 to reduce humidity in electric-controlled box, smoothly moisture is drained by exhaust blower 6, thus the moisture Yin Wendu low coagulation reduced in air becomes water droplet to be attached to component surface causes short circuit.
Check valve 10 is set, can ensures that cold-producing medium does not reflux.
The present invention detects temperature in electric-controlled box 1 and humidity condition by temperature sensor 4, humidity sensor 5, and has judged whether moisture requirement by mainboard 2: (be greater than 70% and have dehumidification, be less than 50% without dehumidification).
If there is dehumidification, and the temperature in electric-controlled box 1 is greater than or equal to 27 DEG C, directly opens exhaust blower 6, with outdoor ventilation, is drained by moisture, until electric-controlled box humidity is reduced to 50%, closes exhaust blower 6.
If the temperature in electric-controlled box 1 is less than 27 DEG C, then judge that air compressor 7 is opened or closed condition:
If a compressor cuts out, then open electric heating sheets 3 and heat, time delay opened exhaust blower 6 after 1 minute, with outdoor ventilation, was drained by moisture, until the humidity in electric-controlled box 1 is reduced to 50%, closed exhaust blower 6.
If b air compressor 7 is opened, then open magnetic valve 11, open exhaust blower 6, with outdoor ventilation, moisture is drained, until the humidity in electric-controlled box 1 is reduced to 50%, shut electromagnetic valve 11, time delay 30 seconds pass exhaust blowers 6.
If c is during dehumidifying, in electric heating sheets 3 and air compressor 7 handoff procedure, then exhaust blower 6 is held open state, only needs switching solenoid valve 11, and electric heating sheets 3 can not dehumidify with air compressor 7 simultaneously.
