Description
Technical field:
This utility model belongs to technical field of automatic control, especially relates to the intelligent variable frequency control system of a kind of ventilating system.
Background technology:
At present, in building, so that the air circulation of multiple rooms indoor and outdoor, installation ventilating system is generally used to realize；Concrete, common ventilating system is connected the single exhaust equipment in each room by outdoor convulsion unit by blast main, when after the fan starting on outdoor convulsion unit, indoor air is discharged into outdoor via exhaust outlet and blower fan, outdoor fresh air is just through being arranged on the entrance of the air intake vent above window frame or on wall indoor, so that indoor are added to ozone.But the state controlling the converter of fan starting at present uses Artificial Control, the Intelligence Feedback regulation of whole exhausting system can not be realized, the change of convulsion blast main internal pressure can be affected after one or more exhaust equipment indoor is turned on or off, after the negative pressure within blast main diminishes, it is unfavorable for that room air is arranged to outdoor, after the pressure within blast main becomes greatly, the blower fan on outdoor convulsion unit still keeps bigger convulsion power, then can cause the waste of the energy.
Invention
Content:
Technical problem to be solved in the utility model is: provide a kind of indoor convulsion unit by detecting each floor opening and closing situation, control frequency changer and select the intelligent ventilating system that is operated of different capacity.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: the intelligent variable frequency control system of a kind of ventilating system, including being arranged at the indoor exhaust equipment of each floor and being arranged on the outdoor convulsion unit at floor top, the indoor exhaust equipment of each floor is all connected with outdoor convulsion unit by blast main, described intelligent variable frequency control system also includes converter and processor, described outdoor convulsion unit is internally provided with frequency conversion motor, its opening/closing control switch of independent control it is provided with on each described indoor exhaust equipment, the control switch arranged on each described indoor exhaust equipment is all connected with processor individually by the first connecting line, described processor is connected with converter by the second connecting line, described converter is connected with frequency conversion motor by the 3rd connecting line.
As preferably, the frequency of described frequency conversion motor is 1HZ～50HZ.
As preferably, the wind speed within described blast main is maintained at 10m/s～12m/s.
As preferably, described first connecting line uses signal cable, and described second connecting line and the 3rd connecting line all use communication cable.
Compared with prior art, the opening and closing situation having the beneficial effect that processor is switched by the control on detection floor each indoor exhaust equipment internal of the present utility model, being analyzed frequency conversion motor uses great power to be reasonable power, then the data of analysis are delivered to converter, it is operated by Frequency Converter Control frequency conversion motor again, native system has the strongest timely feedback, the wind speed in blast main can be made to remain at 10m/s～12m/s, while guarantee room air smooth discharge to outdoor, do not result in again the waste of energy, and then realize the purpose of energy-saving and emission-reduction.
Accompanying drawing illustrates:
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, indoor exhaust equipment；2, outdoor convulsion unit；21, frequency conversion motor；3, total blower fan；4, converter；5, processor；6, the first connecting line；7, the second connecting line；8, the 3rd connecting line.
Detailed description of the invention:
Below in conjunction with the accompanying drawings and this utility model is described in detail by detailed description of the invention:
nullThe intelligent variable frequency control system of a kind of ventilating system as shown in Figure 1，Including being arranged at the indoor exhaust equipment 1 of each floor and being arranged on the outdoor convulsion unit 2 at floor top，The indoor exhaust equipment 1 of each floor is all connected with outdoor convulsion unit 2 by blast main 3，When one or more indoor exhaust equipment 1 works，Air pressure in blast main 3 is in barotropic state，It is unfavorable for that room air is evacuated to blast main 3 by indoor exhaust equipment 1，Now outdoor convulsion unit 2 opens work，Blast main 3 is internal is in negative pressure state，Reduce the convulsion power required for indoor exhaust equipment 1，Therefore indoor exhaust equipment 1 has only to the air that less power can be indoor and is evacuated to blast main 3，Avoid owing to indoor exhaust equipment 1 power is excessive and cause the excessive problem of indoor noise，Described intelligent variable frequency control system also includes converter 4 and processor 5，Described outdoor convulsion unit 2 is internally provided with frequency conversion motor 21，Its opening/closing control switch of independent control it is provided with on each described indoor exhaust equipment 1，The control switch arranged on each described indoor exhaust equipment 1 is all connected with processor 5 individually by the first connecting line 6，Described processor 5 is connected with converter 4 by the second connecting line 7，Described converter 4 is connected with frequency conversion motor 21 by the 3rd connecting line 8，Processor 5 can gather the opening and closing situation controlling switch on each indoor exhaust equipment 1，According to the difference controlling switch open quantity detected，Analyzing frequency conversion motor 21 uses great power to be reasonable power，Then the data of analysis are delivered to converter 4，Controlled frequency conversion motor 21 by converter 4 again to be operated，Each opening and closing situation controlling switch can be used for quickly detecting and process by processor 5，All the time control frequency conversion motor 21 and keep rational operating power.
The frequency of described frequency conversion motor 21 is 1HZ～50HZ, and frequency conversion motor 21 selects bigger variable frequency range, and no matter only one of which indoor exhaust equipment 1 works, or when indoor exhaust equipment 1 all works simultaneously, frequency conversion motor 21 all can reach rational rotating speed.
Wind speed within described blast main 3 is maintained at 10m/s～12m/s, and this wind speed, while extracting room air out outdoor, does not results in the waste of energy, has reached the purpose of energy-saving and emission-reduction.
For the ease of feedback and the transmission of signal of signal, described first connecting line 6 uses signal cable, described second connecting line 7 and the 3rd connecting line 8 all to use communication cable.
It is emphasized that: be the most only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, all still falls within the range of technical solutions of the utility model.
