Fig. 3 is the regulator cubicle structural representation.
Among the figure: 1. refrigerator, 3. regulator cubicle, 5. room, 7. discharge pipe, 9. backwind tube, 11. air outlets, 13. air inlets, 15. air channels, 17. ceilings, 19. return air inlets, 21. Temperature Humidity Sensors, 23. fresh wind ports.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Refrigeration air-supply system of electric cabinet shown in Fig. 1-2, comprise refrigerator 1 and regulator cubicle 3, this refrigerator 1 is positioned at the outside in room 5, this regulator cubicle 3 is positioned at the room 5 of sealing, the both sides of refrigerator 1 are distributed with discharge pipe 7 and backwind tube 9, the upside of regulator cubicle 3 is provided with air outlet 11 and downside is provided with air inlet 13, offer underground air duct 15 in the room 5, this air channel 15 is connected with discharge pipe 7, air inlet 13 respectively, the ceiling 17 in room 5 is provided with return air inlet 19, and this return air inlet 19 is connected with backwind tube 9.Wherein, also be provided with Temperature Humidity Sensor 21 in the room 5, be used to detect the temperature and humidity in the room, in time the control device to refrigerator 1 provides data, so that refrigerator is in time adjusted temperature and humidity.Also offer fresh wind port 23 on the refrigerator 1, make outside new wind enter refrigerator 1, mix feeding discharge pipe 7 through filtration with the wind that has freezed.Refrigerator 1 motor adopts the frequency converter regulating frequency, by the output frequency of adjusting refrigerator 1 motor frequency conversion device, thereby makes air output reach balance.
As shown in Figure 3, the air inlet 13 of regulator cubicle 3 and the return air inlet 19 of refrigerator 1 are provided with screen pack, and air inlet 13 screen pack that adopts nonwoven cloth materials to make, be used to filter fine dust, and return air inlet 19 adopt metal filter screens.
The present invention realizes in the following way: at first, regulator cubicle 3 is installed in the room 5 that has underground air duct 15, simultaneously air channel 15 is connected with the air inlet 13 of regulator cubicle 3.Then refrigerator 1 is installed on 5 tops, room, wherein, the discharge pipe 7 of refrigerator 1 is connected with air channel 15, and the backwind tube 9 of refrigerator 1 is connected with return air inlet 19 on being installed on ceiling 17, then regulator cubicle 3 bottom sealing plates are being replaced with the nonwoven fabrics screen pack, so that refrigerator 1 cold wind from the nonwoven fabrics screen pack by sending, like this, the nonwoven fabrics screen pack is not only as regulator cubicle 3 bottom air inlet mouths 13 but also reach the effect of filtering cold wind.Open refrigerator 1 and make chilled water Inlet and outlet water pipe valve, start refrigerator by refrigerator 1 control cubicle, the intake of refrigerator 1 can be regulated by the air supply motor rotating speed (variable frequency control) that control cubicle is regulated refrigerator.Subsequently, after refrigerator 1 started, outside new wind entered fresh wind port 23, sent and arrived regulator cubicles 3 bottoms by underground air duct 15 from cold wind discharge pipe 7 through filtering with the freezing cold wind that becomes, and arrived regulator cubicle 3 inside by the nonwoven fabrics filter screen.Cold wind exchanges with element institute caloric value voluntarily in regulator cubicle 3 inside, becoming hot blast discharges from regulator cubicle 3 top air outlets 11, accumulate in sealing ceiling 17 tops after hot blast is discharged, and arrive backwind tube 9, return refrigerator 1 fresh wind port 23 and utilize again by ceiling 17 return air inlets 19.For electrical energy saving, and reach regulator cubicle 3 adapt circumstance requirements, in different seasons, can be by regulating the output frequency of air supply motor frequency converter in refrigerator 1 control cubicle, thus make air output reach balance, electrical energy saving is also taken away heat.
This regulator cubicle 3 cooling air-supply arrangements make full use of cross-ventilated principle, and cold wind is got back to the system bottom, and hot blast arrives the top, forms a cyclic process, and in the air-conditioning cyclic process, electric component institute caloric value is difficult for piling up, and element over-temperature is damaged; Cold air is sent into and is passed through twice filtration in the regulator cubicle, has guaranteed to be difficult in the regulator cubicle accumulating dust, and has prolonged the useful life of electric component; In the whole circulation process, no matter be that return air or new wind all cool off by chilled water, the cold wind of guaranteeing to enter in the regulator cubicle is relatively drier, reaches the humidity environment of regulator cubicle 3 operations, and dewfall does not form the globule, has avoided the generation of electric component fault.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
