Square T and by T compared with Tac, to judge whether to need the movement that is dusted.It realizes locating for different type of machines, the type
Under the influence of the factors such as area, weather, the best opportunity of the dedusting of each unit is determined, meet hommization and industrialization is set
Meter.
Detailed description of the invention
It to describe the technical solutions in the embodiments of the present invention more clearly, below will be to embodiment or description of the prior art
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only of the invention some
Embodiment for those of ordinary skill in the art without any creative labor, can also be according to these
Attached drawing obtains other attached drawings.
Fig. 1 is the flowage structure schematic diagram of dust removal method provided in an embodiment of the present invention.
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
Also referring to Fig. 1, now dust removal method provided in an embodiment of the present invention is illustrated.The dust removal method, packet
Include following steps: according to the default blower frequency threshold A for starting detection blower fan load torque of different types of type, dedusting standard
Load torque threshold value Tac, the accumulation of different dusts correspond to different Tac, the load torque of blower under same running frequency
It can increase with the accumulation of dust, and the blower of different frequency is corresponding negative in the case where identical dust accretions amount
Set torque is also to be not quite similar.After above-mentioned parameter is preset, when the running frequency of blower reaches A, detect in reality
Load torque T corresponding to A, T and Tac are compared when use, if T > Tac, are demonstrated the need for and are carried out dust removal operation, instead
It does not need then to be dusted operation, and unit continues to operate normally.
Dust removal method provided by the invention, compared with prior art, according to environmental selection locating for different types, type
Preset parameter threshold required for type, parameter include the fan operation frequency threshold A for starting detection blower fan load torque, dedusting
Standard termination torque Tac.Real-time detection blower frequency be A when actual loading torque T and by T with Tac compared with, thus judge be
The no movement for needing to be dusted.Under the influence of realizing the factors such as the area locating for different type of machines, type, weather, determine
The best opportunity of the dedusting of each unit meets hommization and industrialization design.
Further, referring to Fig. 1, if T > Tac, main control module issues control instruction, and control instruction order unit enters
Continuous alert status simultaneously starts the practical stand-by time of timing, and the preset time of continuous standby is the preset time of continuous alert status
Threshold value is t, and the time of the practical standby mode of unit is t1, compare t and t1Size, if t1> t then starts blower, main control module
It controls the blower reversion and executes dedusting movement, dedusting can also be realized by way of self-cleaning, otherwise will continue waiting for machine
Group is standby, and control blower waits for t1Start blower when > t and executes cleanup action.Equally, different types is in different regions or gas
It waits in use, the preset time of continuous alert status is also to be not quite similar.It should be noted that blower is executing dedusting movement
When, the state that compressor remains shut off guarantees blower not by other so that main control module can obtain the control of blower completely
The influence of factor.
Preferably, after blower exits dedusting mode, the signal that dedusting terminates is issued to main control module, to stop wind in time
The reversion of machine.
Preferably as a kind of specific embodiment of dust removal method provided by the invention, through lot of experiment validation and branch
It holds, t is preferably 5min.The value or value range of default t can be selected according to the actual conditions of type, area or weather.
Preferably as a kind of specific embodiment of dust removal method provided by the invention, according to where type and type
Particular geographic location, the geographical location weather or climate condition selection blower reversing time threshold value t2.Because different
Torque of the type blower in reversion it is different, efficiency of the torque difference in dedusting is also different, it is therefore desirable to be selected according to type
Select threshold value t2Preset value；Similar, locating geographical location is different, and weather and weather reversion to blower and can equally remove
The efficiency tool of dirt has a certain impact.
Further, referring to Fig. 1, timing actual dedusting time t when initially entering dedusting mode3, real-time detection wind
The practical reversion duration t of machine3If t3>t2, blower, which inverts, to be stopped, and scale removal process terminates；It is carried out conversely, blower continues reversion
Dedusting movement, cleanup action continues until t3>t2。
Preferably as a kind of specific embodiment of dust removal method provided by the invention, through lot of experiment validation, t2It is excellent
It is selected as 5min.Default t can be selected according to the actual conditions of type, area or weather2Value or value range.
