To achieve this purpose, the present invention adopts the following technical scheme:
A kind of frequency conversion type electrical cabinet air-conditioning, including shell, the housing chamber indoor the is set to by thermal insulation board segmentation
One chamber and second chamber, the automatically controlled device being set in the first chamber and the system being set in the second chamber
Cooler part；The thermal insulation board offers ventilation opening, and being provided at the ventilation opening prevents condensed water in second chamber from flowing into the
The filter screen of one chamber；The first chamber and the second chamber pass through filter screen perforation connection；The refrigeration device
Including the evaporator being connected with compressor, and it is set up in second chamber for forming the wind of negative pressure in the second chamber
Fan；The first chamber is set as soak chamber, and the second chamber is provided with the drainpipe for condensed water elimination, the steaming
The second chamber wall of hair device side offers air intake.
It wherein, further include the compressor for being set to the first chamber and second chamber periphery.
Wherein, the filter screen is provided with waterproof ventilated membrane.
Wherein, the air-out direction of the fan is oppositely arranged with the ventilation opening.
Wherein, the automatically controlled device is set as control panel and power panel.
Beneficial effects of the present invention: the present invention provides a kind of frequency conversion type electrical cabinet air-conditioning, including shell, pass through thermal insulation board
Segmentation is set to the indoor first chamber of the housing chamber and second chamber, is set in the first chamber automatically controlled device,
And it is set to the refrigeration device in the second chamber；The thermal insulation board offers ventilation opening, is provided at the ventilation opening
Prevent the condensed water in second chamber from flowing into the filter screen of first chamber；The first chamber and the second chamber pass through described
Filter screen perforation connection；The refrigeration device includes the evaporator being connected with compressor, and is set up in second chamber and uses
In the fan for forming negative pressure in the second chamber；The first chamber is set as soak chamber, and the second chamber is provided with
For the drainpipe of condensed water elimination, the second chamber wall of the evaporator side offers air intake.With the design of this structure
Frequency conversion type electrical cabinet air-conditioning can be effectively reduced first by the exchange of first chamber and second chamber cold air and hot-air
The temperature of the indoor automatically controlled device of chamber, and preferable dust-proof effect can be played.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of frequency conversion type electrical cabinet air-conditioning in the present invention.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in connection with fig. 1, it present embodiments provides a kind of frequency conversion type electrical cabinet air-conditioning, including shell 1, passes through thermal insulation board 2
Divide and is set to the indoor first chamber 11 of 1 chamber of shell and second chamber 12, the electricity being set in the first chamber 11
Control device and the refrigeration device being set in the second chamber 12；The thermal insulation board 2 offers ventilation opening 21, described logical
The filter screen 3 for preventing the condensed water in second chamber 12 from flowing into first chamber 11 is provided at air port 21；The first chamber 11
Pass through the filter screen 3 perforation connection with the second chamber 12；The refrigeration device includes the evaporation being connected with compressor
Device 41, and be set up in second chamber for forming the fan 42 of negative pressure in the second chamber 12；The second chamber 12
It is provided with the drainpipe 5 for condensed water elimination, the second chamber wall of 41 side of evaporator offers air intake 13, into
One step further includes the compressor for being set to the first chamber and second chamber periphery, filter screen 3 described in the present embodiment
It is provided with waterproof ventilated membrane, filter screen is set to ventilation opening close to the side for being located at second chamber.
In addition, the generated temperature difference causes the first chamber between first chamber and second chamber in order to prevent in the present embodiment
Chamber interior walls generate condensed water, and the first chamber 11 in above-described embodiment is set as soak chamber.
The air-out direction of fan 42 described in the present embodiment is oppositely arranged with the ventilation opening 21, the automatically controlled device setting
For control panel 51 and power panel 52.
The frequency conversion type electrical cabinet air-conditioning designed using the above structure, when the hot-air in first chamber is flowed by filter screen 3
Enter to after second chamber, under the vortex effect generated between fan and thermal insulation board, so that generating certain bear in second chamber
Pressure, while but also sufficiently being exchanged between hot-air and cold air, generation condensed water is simultaneously discharged by drainpipe 5, while cold wind
Also it can be flowed into first chamber by filter screen, the control panel 51 and power panel 52 to its inside carry out effective temperature-reducing.
Full DC frequency conversion technology is used on electrical cabinet air-conditioning, energy-efficient, makes to run relatively reliable, DC frequency converting air-conditioner friendship
It is a relatively unstable process, reliability of operation, stability is poor, full DC frequency-changing electrical cabinet when flowing electric machine speed regulation
The direct current generator of air-conditioning uses blushless operation technology, can adjust revolving speed by changing voltage or electric current, run more reliable.Quan Zhi
Galvanic electricity machine has smooth and economical starting and speed adjusting performance, more accurate runing adjustment may be implemented, by full DC frequency-changing skill
Art is used on electrical cabinet air-conditioning, can be controlled compressor and inside and outside fan running simultaneously, is not up to 100% at full capacity
Operating.The control panel that frequency conversion can be achieved is developed, this technology is used for electrical cabinet air-conditioning, and operation is relatively reliable, and runing adjustment is more
Add precisely, by direct current compressor and variable ratio frequency changer control panel, under high temperature environment, implements the revolution for inhibiting compressor temperature to rise
Control, even if being also able to carry out cooling in the case where previous constant speed compressor will start defencive function, stop cooling hot environment
Highest energy conservation is operated up to 40%.And frequency conversion electrical cabinet air-conditioning internal core segment, in circuit control part, other frequency conversion drive
Big with system control part calorific value, general electrical cabinet air-conditioning use is high in temperature, the place more than dust, greasy dirt, in design internal junction
When structure, dust, greasy dirt can be solved the problems, such as by reinforcing leakproofness, and the high situation of temperature is not well solved, therefore
Through the design of above-mentioned frequency conversion type electrical cabinet Air Conditioning Scheme, while playing preferable cooling effect, additionally it is possible to play preferably
Dust-proof effect.
