Further; Said bypass refrigeration pipe comprises bypass evaporator and solenoid valve; One end of said bypass evaporator is communicated with the evaporator end of the compressor of refrigeration system; One end of said solenoid valve is communicated with the evaporator end of the heating power expansion valve of refrigeration system, and the other end of said bypass evaporator is communicated with the other end of solenoid valve, and said solenoid valve is electrically connected with robot control system(RCS) and is controlled by robot control system(RCS).Refrigeration system is told a branch road come the air in the electrical control cubicles is carried out cool-down dehumidification, realize moisture-proof role, simple and practical.
Further, said bypass evaporator is located at the cabinet bottom.Make the condensate water that generates on the bypass evaporator can not exert an influence to the electric elements in the electrical control cubicles.
Further, said bottom of cabinet bulk is provided with freeing port.Be convenient to get rid of condensate water.
Further, said freeing port is located under the bypass evaporator.The simple condensate water of directly discharging.
Further, said temperature elevation system comprises the electric heater that is located at the cabinet bottom, and said electric heater is electrically connected with robot control system(RCS) and is controlled by robot control system(RCS).Reduce relative humidity, be difficult for condensation and drip, thereby reach moisture-proof role.
Further, said ventilating system comprises the air inlet that is located at the cabinet bottom, is located at blower fan corresponding with air inlet in the cabinet and is located at the air outlet on cabinet top.
After adopting technique scheme, the present invention has following advantage: freezing and heating two kinds of systems cooperates the moisture-proof role of realizing all situations, and moisture effect is good; Relatively simple for structure, utilize the robot control system(RCS) of electrical control cubicles itself can realize low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
An embodiment of the present invention as shown in Figure 1; A kind of moistureproof electrical control cubicles; Comprise cabinet 1; Be provided with ventilating system in the said cabinet; Be provided with the robot control system(RCS) 2 of control ventilating system work in the said cabinet, be provided with in the said cabinet and be communicated with the outside refrigeration system 3 of cabinet and, be provided with by robot control system(RCS) control in the said cabinet and when refrigeration system is not worked, heat the temperature elevation system of protection against the tide by the bypass refrigeration pipe of robot control system(RCS) control; Be provided with the humidity sensor 4 that detects air humidity in the said cabinet, the moisture signal that said robot control system(RCS) is gathered humidity sensor is during greater than setting value and when refrigeration system move, be communicated with the bypass refrigeration pipe or startup temperature elevation system when refrigeration system is shut down.Said ventilating system comprises the air inlet 12 that is located at the cabinet bottom, be located at blower fan corresponding with air inlet in the cabinet 13 and be located at the air outlet 14 on cabinet top.
In the present embodiment; Said bypass refrigeration pipe comprises bypass evaporator 5 and solenoid valve 6; One end of said bypass evaporator is communicated with the evaporator end of the compressor 31 of refrigeration system; One end of said solenoid valve is communicated with the evaporator end of the heating power expansion valve 32 of refrigeration system, and the other end of said bypass evaporator is communicated with the other end of solenoid valve, and said solenoid valve is electrically connected with robot control system(RCS) and is controlled by robot control system(RCS).Preferably said bypass evaporator is located at the cabinet bottom, makes the condensate water that generates on the bypass evaporator can the electric elements in the electrical control cubicles not exerted an influence like this.For the ease of getting rid of condensate water, said bottom of cabinet bulk is provided with freeing port 11.And preferably said freeing port is located under the bypass evaporator, draining is directly simple more like this.Said temperature elevation system comprises the electric heater 7 that is located at the cabinet bottom, and said electric heater is electrically connected with robot control system(RCS) and is controlled by robot control system(RCS).
Principle of work of the present invention is specific as follows:
1, refrigeration system duty, robot control system(RCS) is in running order, opens blower fan this moment, and new wind is introduced from air inlet, discharges from air outlet, forms vent passages; Robot control system(RCS) is gathered the moisture signal of humidity sensor; When humidity during greater than setting value, robot control system(RCS) is opened solenoid valve is communicated in the pipeline of refrigeration system the bypass evaporator, utilizes the direct evaporative cooling dehumidifying of bypass evaporator; Realize moisture-proof role, condensate water is got rid of from freeing port.
2, refrigeration system stopped status, robot control system(RCS) is in holding state, and this moment, robot control system(RCS) was gathered the moisture signal of humidity sensor, when humidity during greater than setting value; Robot control system(RCS) is sent instruction and is started blower fan, starts electric heater, and this stylish wind is introduced from air inlet, because hot-air density is littler than cold air density; So new wind, helps the mobile last electrical control cubicles of discharging to the air outlet place through the electric heater heat temperature raising, according to the air-treatment principle; This is that an approximate water capacity is constant, and temperature raises, the process that relative humidity reduces; After relative humidity reduced, air ran in the electrical control cubicles electric components and is difficult for condensation and drips, and so just realizes moisture-proof role.
