Fig. 1 is the overall flow figure of dust collection method according to an embodiment of the invention.
Step S100: the humidity value and the dust concentration at the air inlet place in sensor sensing air channel.
Humidity value is a rh value, is the absolute humidity of humid air and the ratio of the maximum absolute humidity that uniform temp possibly reach down, also can be in the humid air ratio of water saturation pressure under the steam partial pressure and uniform temp.Sensor is a relative humidity sensor, and this sensor is set at the air inlet place in air channel, the rh value of the air at sensing air inlet place, that is, and the rh value of the air in the sensing machine room.In the present embodiment, the rh value in the air ambient of the common sensing of relative humidity sensor server room.Sensor is the dust concentration sensor, and this sensor is arranged on the air inlet place in air channel, monitors the dust concentration in the air ambient.Dust concentration is also claimed dust content or air purity, and for example, the particle diameter of dust is more than or equal to the dust number of 0.5 μ m.In the present embodiment, the dust concentration in the air ambient of the common sensing of dust concentration sensor server room.
Step S102: when humidity value during more than or equal to the first humidity threshold value, control device starts dehydrating unit, so that dehumidification operation is carried out in the air channel.
In this step; Control device compares the rh value and the first humidity threshold value (being the first relative humidity threshold value) of relative humidity sensor institute sensing; For example; In this embodiment; The first humidity threshold value is 65%, and the user can be provided with the first humidity threshold value through control device before start; If be provided with in advance, then control device turns round according to the default value that supplier is provided with.In addition, can change the first humidity threshold value, for example, can the first humidity threshold value be set to, also can the first humidity threshold value be set to greater than 65% less than 65% according to user's demand.When relative humidity during more than or equal to the first humidity threshold value; Control device starts dehydrating unit; Dehumidifying blower fan in the dehydrating unit is sent into the air channel with wet gas by air inlet; In the air channel, humid air is dehumidified; Then through outside the air discharge machine of dehumidifying blower fan with drying; Air in the machine room circulates again and again, thereby has reduced indoor humidity.
Step S104: when humidity value was less than or equal to the second humidity threshold value, control device cut out dehydrating unit, to stop dehumidification operation.
In the dehumidification operation process; Control device compares the rh value and the second humidity threshold value (being the second relative humidity threshold value) of relative humidity sensor institute sensing; For example; In this embodiment, the second relative humidity threshold value is 50%, as stated; The user can be before start; Through control device the second humidity threshold value is set, if be provided with in advance, then control device turns round according to the default value that supplier is provided with.In addition, can change the second humidity threshold value, for example, can the second humidity threshold value be set to, also can the second humidity threshold value be set to greater than 50% less than 50% according to user's demand.And, during dehumidification operation, can reset the second humidity threshold value according to the requirement of user to the machine room air ambient.When the relative humidity of machine room air was less than or equal to the second humidity threshold value, control device cut out dehydrating unit, stops dehumidification operation.

In this step; Control device compares the dust concentration and the first dust concentration threshold value of dust concentration sensor institute sensing, for example, and in this embodiment; The first dust concentration threshold value is a dust particle diameter more than or equal to the dust number of 0.5 μ m is 1,8000/cm
3When dust concentration during more than or equal to this first dust concentration threshold value; Control device starts dust arrester; Dedusting fan in the dust arrester is sent into the air channel with dusty gas by air inlet; (low efficient filter filters the bigger dust of particle diameter by thick effect, inferior high efficiency filter; Inferior high efficiency filter filters the less dust of particle diameter) filter; Dust is delayed at filter surfaces; Purifying back gas is taken out by force by high pressure positive blower; Outside air outlet is expelled to the air channel; Directly enter indoor (but also air duct drains into outdoor); Wherein, efficient, inferior high efficiency filter has filter core respectively.In the present embodiment, filter core adopts filter screen, and high efficiency particulate air filter has coarse strainer, and inferior high efficiency filter has fie screen.Because having two kinds of filters filters, thereby can realize good dust removing effects.In other embodiments, can also adopt other filter cores, for example, wire-wound filter core, foldable filter element, activated carbon cartridge, resin filter element etc.
Step S108: when dust concentration was less than or equal to the second dust concentration threshold value, control device cut out dust arrester, to stop dust removal operation.In this step; Control device compares the dust concentration and the second dust concentration threshold value of dust concentration sensor institute sensing, for example, and in this embodiment; The second dust concentration threshold value is a dust particle diameter more than or equal to the dust number of 0.5 μ m is 15,000/cm
3When dust concentration was less than or equal to this second dust concentration threshold value, control device cut out dust arrester, thereby stops dust removal operation.
Adopt above-mentioned dehumidifying dust collection method; Can be according to the user to the humidity of machine room working environment and the requirement of dust concentration; The first humidity threshold value, the first dust concentration threshold value, the second humidity threshold value and the second dust concentration threshold value are set flexibly, thereby in the scope that the humidity and the dust concentration of machine room working environment is controlled at customer requirements.The dehumidifying control device can be respectively controlled the startup of dehumidifying dust removal operation automatically and is stopped based on the first humidity threshold value and the second humidity threshold value and the first dust concentration threshold value and the second dust concentration threshold value; Wherein, When the relative humidity of air in the machine room and dust concentration during respectively greater than the first humidity threshold value and the first dust concentration threshold value; Dehumidify respectively and dust removal operation; In dehumidifying and dust removal operation process; If the relative humidity of the air in the machine room, in time stops to dehumidify and dust removal operation during respectively less than the second humidity threshold value and the second dust concentration threshold value with dust concentration.Thereby realized the automatic control of dehumidifying dust removal operation is helped energy savings, and improved the service life of dehumidifying dust pelletizing system.
In addition; With freestanding dust arrester and the dehydrating unit machine that becomes one; The humidity and the dust concentration that can satisfy the machine room air ambient require than higher demand simultaneously; And can be according to the needs of machine room air ambient; Can start dehydrating unit and dust arrester simultaneously; Perhaps start one of dehydrating unit and dust arrester, can utilize the energy to greatest extent, thereby avoided unnecessary energy ability expense.In addition, the dehumidifying dust removing integrated machine is compact, and the space that takies machine room reduces, and can save the useful space for machine room.
Fig. 2 is the flow chart of dust collection method of dehumidifying according to an embodiment of the invention.
Step S200: the humidity value and the dust concentration at the air inlet place in sensor sensing air channel.
Step S202: when humidity value during more than or equal to the first humidity threshold value, control device starts dehydrating unit, so that dehumidification operation is carried out in the air channel.
Dehydrating unit comprises: be arranged on the air channel air inlet and/or air outlet place the dehumidifying blower fan be arranged on the heat exchanger in the air channel.Heat exchanger is with the equipment of the part heat transferred cold fluid of hot fluid, claims heat exchanger again.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.Heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc. in Chemical Manufacture, uses more extensive.
In the present embodiment, heat exchanger is as condenser.In the present embodiment, control device starts dehydrating unit, when just starting the dehumidifying blower fan, opens the refrigerant control valve of heat exchanger.In dehumidification operation; Get into the humid air in air channel through the dehumidifying blower fan; Pass through heat exchanger; Steam in the humid air condenses into water when passing through heat exchanger; From air, separate; Therefore humid air becomes dry air, through the dehumidifying blower fan dry air is entered indoorly, and the continuous circulation through air realizes dehumidifying.
Can before dehumidification operation or in the dehumidification operation, the dehumidifying rotation speed of fan be set, when comprising two dehumidifying blower fans, start and stop two dehumidifying blower fans simultaneously, and the speed of dehumidifying blower fan is identical with other parameters.Through pulse width modulation (PWM) the dehumidifying blower fan is carried out speed governing, the rotating speed of dehumidifying blower fan be divided into n grade (that is, 0 grade, 1 grade, 2 grades, 3 grades ... (n-1) grade).For example, when the dehumidifying rotation speed of fan is divided into 16 grades and dehumidifying rotation speed of fan when being the 15th grade, the maximum air detergent power of dehydrating unit is 15 cubic metres/min.In order to handle dust in air effectively, can handle the air total amount according to dehydrating unit in a hour and approximate machine room space magnitude proportion, dispose the quantity and the rotating speed that the dehumidifying blower fan is set of dehumidifying blower fan.For example, when the machine room space is 800 cubic metres, the maximum processing capability of dehydrating unit be 900 cubic metres/per hour, then rotation speed of fan should be set to 14 grades or 15 grades.
Step 204: control device is presented at temperature value in the air channel in the scheduled time and humidity value on the display unit.
In dehumidification operation; In order to allow the user understand the variation tendency of air themperature and humidity simply, intuitively; According to the indication of control device, on screen, show temperature value and the humidity value in the scheduled time with video data and display unit of record statistical function.Fig. 3 is the diagrammatic sketch according to the duty of embodiments of the invention display unit displays temperature, humidity, dehydrating unit on screen and dehumidifying rotation speed of fan.For example, in the present embodiment, display unit is 4.3 cun a color LCD display unit.In addition, can select other sizes and type according to user's needs.Can select the length of the scheduled time arbitrarily, in the present embodiment, select 1 hour, that is, on display screen, show the change curve in temperature value and the humidity value 1 hour of air in the machine room.As shown in Figure 3, the duty and dehumidifying rotation speed of fan that also on display screen, show dehydrating unit.
In addition, when humidity in the given time changes and/or variations in temperature when unusual, control device shows that on display unit the equipment state in the machine room of living in space in air channel is unusual.When temperature in the given time remains unchanged and humidity continues to increase or reduce; Or humidity remains unchanged, and temperature is lasting to be changed rapidly; Promptly; Increase rapidly or reduce; And dehumidification operation is normally carried out and the lasting rising of temperature; Or the humiture rate of change is unusual; Apparatus of load variation abnormality in the environment then is described; And this dehydrating unit is used in the machine room working environment; So control device passes through to eject the form display device abnormal state of dialog box on the screen of display unit, thereby the prompting user checks server, machine room refrigeration plant, machine room controller switching equipment etc.For example; The operating temperature of machine room is 20 ℃～25 ℃; Rate of temperature change＜5 ℃/hour; When emitting great amount of heat when server operation operation irregularity; Cause the computer room temperature fast rise and surpass rate of temperature change or surpass 30 when spending; Temperature sensor just can sense this abnormal temperature value; And indication according to control device; To eject the form display device abnormal state of dialog box; Thereby prompting customer inspection server, machine room refrigeration plant, machine room controller switching equipment etc. guarantee these calculator room equipment security of operation.
Step S206: when humidity value was less than or equal to the second humidity threshold value, control device cut out dehydrating unit, to stop dehumidification operation.In addition, control device cuts out dehydrating unit, when just closing the dehumidifying blower fan, closes the refrigerant control valve of heat exchanger.
In this embodiment, the machine room working environment is carried out dehumidification operation,, control dehumidification operation automatically, ambient humidity is controlled in the humidity range of customer requirements through the first humidity threshold value and the second humidity threshold value are set.And can on the screen of display unit, show temperature value and the change curve of humidity value in the scheduled time, make the user can simple, intuitive ground understand the variation tendency of temperature and humidity of the air of machine room.In addition, the server working environment state in can monitoring room, thus good working environment is provided for the equipment such as server in the machine room.
Step S208: when dust concentration during more than or equal to the first dust concentration threshold value, control device starts dust arrester, so that dust removal operation is carried out in the air channel.
In the present embodiment, dust arrester comprises: be set at the air channel the air inlet place dedusting fan and/or be set at the dedusting fan at the air outlet place in air channel.Can before dust removal operation or in the dust removal operation, the dedusting fan rotating speed be set, when comprising two dedusting fans, start and stop two dedusting fans simultaneously, and the speed of dedusting fan be identical with other parameters.(PWM) carries out speed governing to dedusting fan through pulse width modulation, the rotating speed of dedusting fan be divided into n grade (that is, 0 grade, 1 grade, 2 grades, 3 grades ... (n-1) level).For example, when the dedusting fan rotating speed was divided into 16 grades and dedusting fan rotating speed and is the 15th grade, the maximum air detergent power of dust arrester was 15 cubic metres/min.In order to handle dust in air effectively, can handle the air total amount according to dust arrester in a hour and approximate machine room space magnitude proportion, dispose the quantity and the rotating speed that dedusting fan is set of dedusting fan.For example, when the machine room space is 800 cubic metres, the maximum processing capability of dust arrester be 900 cubic metres/per hour, then rotation speed of fan should be set to 14 grades or 15 grades.
The air channel is being carried out in the dust removal operation, for example, can draw two ventilation ducts that diameter is identical from the air inlet in air channel with air outlet respectively, have respectively in these two ventilation ducts air inlet surrounding air and air outlet carry out the air after the dust removal process.The air pressure of these two kinds of air is applied on the filter core replacing warning device.Those skilled in the art can expect and through other mode gas pressure changed warning device in filter core.When the filter open type is good; Carry out air draught head after the dust removal process less than threshold pressure differential (also can be described as the air pressure difference overload alarm threshold value of air inlet and air outlet) in the air inlet in surrounding air and the air outlet; Dust is too much on the filter surface; When stopping up filter screen; The filter permeability reduces, thereby there is big pressure differential in the air after the dust removal process in surrounding air in the air inlet and the air outlet.
Step S210: when the difference of second air pressure at first air pressure at air inlet place and air outlet place during greater than threshold pressure differential, filter core is changed warning device and is sent filter core to control device and change and report to the police.

Before dust removal operation or in the dust removal operation, after speed had been set, threshold pressure differential can be provided with through control device.The curve map of Fig. 4 for concerning between the rotating speed of dedusting fan according to an embodiment of the invention and the threshold pressure differential.In Fig. 4, the rotating speed and the threshold pressure differential of dedusting fan are approximated to ratio.Rotating speed according to dedusting fan is provided with threshold pressure differential.For example, can threshold pressure differential be provided with between the 100Pa to 400Pa according to the rotating speed of 0 to 15 grade.For example, when the rotating speed grade was 1 grade, threshold pressure differential was set to 100Pa, and when speed class was 13, threshold pressure differential was set to 340Pa.In addition, can be according to the requirement of user to dust removing effects, threshold pressure differential is set to littler.
In this embodiment, through the speed class of dedusting fan is set in advance, realize the intake adjusting.Change the alarm threshold value of warning device through filter core is set in advance, monitor filter screen permeability state, the prompting user is renew cartridge more in time.When the user has relatively high expectations to air purity, can alarm threshold value be set to lowlyer, realize when the filter screen permeability reduces, can in time reporting to the police, point out the user more renew cartridge.Thereby present embodiment can be realized the comparatively ideal dust removing effects of customer requirements according to user's demands of different.
In addition; Can be under the control of control device, with (for example, 12 grades of the rotating speeds of change curve, blower fan in the humiture parameter of the duty (open and close) of dust arrester, gas one hour; 13 grades, perhaps 15 grades) and filter core change the information of reporting to the police and be presented on the display unit.For example; When threshold pressure differential was set to 200Pa, if the pressure reduction of air inlet and air outlet during greater than 200Pa, filter core was changed warning device and is triggered and sends filter core to control device and change and report to the police; And display unit shows the filter core fault according to the indication of control device on the screen.
Step 212: when dust concentration was less than or equal to the second dust concentration threshold value, control device cut out dust arrester, to stop dust removal operation.
In this embodiment, the machine room working environment is carried out dust removal operation,, control dust removal operation automatically, the dust concentration of environment is controlled in the dust concentration scope of customer requirements through the first dust concentration threshold value and the second dust concentration threshold value are set.
