Master controller includes data processing module, and the real time temperature Toe for receiving the condenser coil come is transferred at data Manage module, the corresponding table of different temperature ranges and condensation fan running frequency built in data processing module, master controller according to The real-time Toe values that monitoring comes select corresponding fan operation frequency, and transmit a signal to master controller, by master controller come pair The running frequency of condensation fan is regulated and controled.So that the operating of wind turbine is realized real-time monitoring, rather than be constantly in and run at high speed, drops Low operation noise, extends the service life of condensation fan.
Further to accurately control the running frequency of condensation fan, master controller receives real-time Toe values and is transferred to number After processing module, data comparison is carried out first, and judging newest real-time Toe values, whether the Toe values once monitored in original exist In corresponding table in residing temperature range, such as newest real-time Toe values maintain the operating frequency of condensation fan still in former section It is constant;When data it was found that, when Toe values rise or fall and are more than former temperature range, Toe values are rejudged in corresponding table Residing temperature range, it is cold to adjust in real time by frequency converter according to the new corresponding condensation fan running frequency of temperature range The running frequency of solidifying wind turbine.
There are two directions for the variation of Toe values:Rise or decline, therefore, in the present invention, prestores in data processing module There are two table, during the raising and lowering for corresponding to Toe values respectively, the operation frequency of the corresponding condensation fan in different temperatures section Rate selects different condensation fan running frequencies when condenser coil temperature is gradually increasing and declines process.
When the newest Toe values rising detected, and beyond the model of the temperature range residing for the last Toe values detected When enclosing, the running frequency of corresponding condensation fan is searched according to subordinate list 1.
Condensation fan running frequency is tabled look-up when 1 condenser coil temperature of table rises
As shown in Table 1, fan operation frequency is divided into n grades, correspondingly, being corresponding with the continuous humidity province of n condenser coil Between, each temperature range is arranged by the ascending order of temperature, and also the deduction of degree of liter arranges the running frequency of corresponding condensation fan, with condenser coil The rising of temperature, condensation fan running frequency increase, and improve the cooling-down effect to condenser.When the condenser coil detected begins It is less than Toe eventually1When (minimum temperature of master controller or the condenser tube of data processing module identification), condensation fan is not transported Turn, with the rising of temperature, when the real time temperature of condenser coil is in [Toe1,Toe2) when, condensation fan starts with f1Frequency Rate operates, and cools down for condenser, with the temperature rise of condenser coil, when the Toe values detected in real time constantly change, is more than Within the scope of primary residing temperature range, when different temperatures section in table 1, existed according to Toe values by data processing module Suitable fan operation frequency is selected in table 1, when condenser coil temperature is more than ToenAfter, it is main regardless of temperature rises Controller is given tacit consent to the highest frequency f of wind turbinenOperating.Each temperature range is continuous in table 1, can be through each temperature of lot of experiment validation Spend the specific temperature division in section and corresponding condensation fan running frequency.
The master controller of air-conditioner set receives starting-up signal, and compressor is first begin to work, drive refrigerant in pipeline and Operating in the refrigeration system for the closed loop that condenser, throttling set and evaporator are formed realizes refrigeration or heating, in air-conditioner set system In cold or heating operations, the temperature of condenser coil can constantly change, the temperature sensor being arranged on condenser coil 23 monitor the temperature change of condenser coil in real time, and temperature value is transferred to the master controller of air-conditioner set.With air-conditioner set For refrigeration, booting beginning, the temperature of condenser coil is essentially room temperature, and condensation fan is simultaneously inoperative, as air-conditioner set is opened The growth of run time after machine, the temperature of condenser coil constantly rise, and the real-time Toe values that temperature sensor detects are in table When in a certain temperature range in 1, according to corresponding wind turbine frequency values come by Frequency Converter Control condensation fan with this frequency run, Need to illustrate when because being divided in temperature range thinner, and condenser coil temperature rises very fast, and regulates and controls condensating wind every time Machine needs separated in time, and therefore, within this interval time, the temperature of condenser coil may rise to certain in table 1 One temperature range, condensation fan directly with the corresponding frequency run of the temperature range, do not represent the operating frequency one of condensation fan Surely it to be gradually risen from 0 through minimum operating frequency, it is possible to which the Toe values of last time detection are still less than Toe1, and examine next time The Toe values measured directly rise to [Toe4,Toe5) temperature range, then before the operating frequency of condensation fan is directly skipped Three operating frequencies, directly with [Toe4,Toe5) the corresponding operating frequency of temperature range start running.
When the newest Toe values decline detected, and less than the model of the temperature range residing for the last Toe values detected When enclosing, the running frequency of corresponding condensation fan is searched according to subordinate list 2.
Condensation fan running frequency is tabled look-up when being risen under 2 condenser coil temperature of table
As shown in table 2, during condenser coil temperature declines, n temperature range is equally set and n corresponding Condensation fan running frequency.Condenser coil temperature decline includes three kinds of situations:
1. ambient temperature declines;
2. air-conditioner set is shut down, refrigerant shuts down;
3. the operating frequency of compressor declines, especially frequency-changeable compressor, operating frequency with cooling time propulsion, Indoor (in compartment) temperature declines, and required refrigerating capacity declines, and compressor operation frequency reduces, and band condenser temperature declines.
Tables 1 and 2 is combined it is found that increasing Toe in table 20Endpoint value, and n temperature range is similarly, by temperature liter Sequence arranges, and corresponding condensation fan running frequency is from 0 to fnAscending order arranges, when detecting that condenser coil temperature Toe declines, The temperature range residing for instantaneous value using data processing module from table 2 according to Toe selects corresponding condensation fan operation frequency Rate.When detecting that real-time Toe values decline for the first time, and not in original temperature range, such as when dropping to its adjacent temperature When section, the running frequency of condensation fan is constant, when dropping to next temperature range, with low one grade of the fortune of former running frequency Line frequency operates.Condenser coil temperature reaches ToenAfter above, condensation fan is with fnHighest frequency continuous running, if occur Any one in three kinds of situations above-mentioned, causes condenser coil temperature to decline, and the Toe values detected in real time decline, if first The real-time Toe values of the secondary decline detected are less than ToenBut it is more than Toen-1When, into highest temperature range in table 2, at this point, The running frequency of condensation fan is constant, still with highest frequency fnOperating, drops to another temperature range [Toen-2,Toen-1) when, With fn-1Frequency operation (the temperature rise stage in this way, at this time the running frequency of condensation fan should be fN-2,Differ a frequency Value).Similarly, when temperature rise is to arbitrary temperature range, when detecting that temperature drops below this temperature range to adjacent temperature When spending section, the running frequency of condensation fan remains unchanged, and continues decline process, corresponding cold according to temperature range listed by table 2 Solidifying fan operation frequency is regulated and controled.Certainly, decline process is not declined by adjacent temperature range one by one, it is possible to work as interval After a certain period of time, the more previous temperature value of again/real-time Toe values for detecting for the first time declines several temperature ranges, is selected according to table 2 The running frequency of corresponding condensation fan.The decline of condenser coil temperature is dropped, and the running frequency of condensation fan is also corresponding It reduces, to reduce energy consumption, extends the service life of condensation fan, the compression ratio for maintaining refrigeration system certain, to ensure compressor Normal oil return extends the service life of air-conditioner set compressor.
To avoid frequently regulating and controlling fan operation frequency, the frequent fluctuation of condensation fan running frequency is effectively avoided, The fluctuation for reducing refrigeration system, and further increases the service life of wind turbine, according to the condenser coil temperature Toe detected into After the adjustment of row condensation fan running frequency, when needing to calculate after Ts, previously described method carries out condensation fan running frequency for another example Regulation and control next time.
Can be real-time after being spaced Ts it should be noted that being used to the Toe values of condensation fan running frequency every time Value, i.e., every TS seconds, temperature sensor collects the real time temperature of primary condenser coil pipe, and this temperature is sent out in the form of a signal Master board is given, and is compared temperature range and corresponding condensation fan residing for analysis, lookup in data processing module Running frequency, by the running frequency of Frequency Converter Control condensation fan, i.e. rotating speed.
But this method relative error is larger, therefore, in the embodiment of the present invention, to the method for condensation fan FREQUENCY CONTROL In further include data acquisition and filtering, i.e., regulate and control the running frequency of condensation fan by the way of temperature averages, I.e. in the Ts of each time interval, temperature sensor can repeatedly collect real-time temperature signal, and be filtered place to signal Reason, avoids data from interfering, and sends filtered temperature signal to master controller and data processing module, is delayed after Ts, data The multiple temperature signals being collected into are weighted processing module, the weighted average in Ts are obtained, according to weighted average Value carries out the regulation and control of the running frequency of condensation fan.Further, temperature averages are calculated using moving weighted average method, It is more balanced and accurate to calculate the temperature averages that get using moving weighted average method, especially the temperature of condenser coil compared with In the case of height, control mode is more accurate, and cooperation filtering, control data fluctuations effect is good, further increases control accuracy.
It should be noted that air-conditioner set provided by the invention and condensation fan running frequency control method, are not only fitted For air-conditioner set used for rail vehicle, it is equally applicable to domestic or commercial common air-conditioning unit, is not requiring air-conditioner set to make In the case of frequency-changeable compressor, the frequency conversion control of condensation fan running frequency is realized, meanwhile, this control method is same suitable For the frequency control of evaporator ventilation blower, frequency converter is set on ventilation blower, temperature sensing is set on evaporator coil Pair in evaporator coil temperature section and evaporator air mover cover running frequency is arranged in device in the data processing module of master controller Table is answered, using previously described condensation fan control method for frequency, evaporator air mover cover running frequency is regulated and controled.Certainly, In an air-conditioner set, can frequency converter be set on condensation fan and evaporator air mover cover simultaneously, respectively to condensation fan and Evaporator air mover cover carries out running frequency and is regulated and controled.
