Below, utilize flow chart and voltage plot to be described in detail in and have the method for when having supplied with abnormal voltage in the air regulator structure like above-mentioned structure the driving of above-mentioned compressor (21) having been controlled.
Fig. 3 shows the circuit diagram of structure of the abnormal voltage test section of the embodiment of the invention.
With reference to Fig. 3, the abnormal voltage test section (131) of one embodiment of the invention is integrally formed on the control substrate of the inside that is installed on indoor set (10).That is, this abnormal voltage test section (131) adopts and is built in the inner structure of indoor set, rather than the external equipment of establishing in addition.
Say that at length above-mentioned abnormal voltage test section (131) detects abnormal voltage through utilizing the RMS voltage detecting of power transformer from the input power supply.That is the abnormal voltage that, is detected is the ac voltage that flows within doors.
Above-mentioned abnormal voltage test section (131) has: the power transformer (131a) that the alternating voltage of being imported is reduced pressure, voltage distribution portion (131d), the noise filter (131e) that will utilize alternating voltage that above-mentioned power transformer (131a) reduced pressure to convert rectification part (131b) and the partes glabra (131c) of DC voltage to, the voltage that converts direct current from interchange to is distributed.
Say that at length above-mentioned power transformer (131a) is connected with power input part (12), the high-tension AC power of power input part (12) input is reduced pressure and forms the AC power of low-voltage.
Above-mentioned rectification part (131b) is made up of a plurality of diodes, and its AC power to low-voltage is carried out full-wave rectification.The power supply of full-wave rectification becomes level and smooth at above-mentioned partes glabra (131c).At this moment, between rectification part (131b) and partes glabra (131c), be connected diode (D6) and capacitor (C1).
Above-mentioned voltage distribution portion (131d) is made up of a plurality of resistance, and its resistance according to a plurality of resistance recently distributes level and smooth power source voltage.Above-mentioned voltage distribution portion (131d) is connected with reference voltage via the diode (D16) that is positioned between first resistance (R1) and second resistance (R2).For example, above-mentioned voltage distribution portion (131d) can make the voltage that is applied to control part (11) reach below the 5V.Above-mentioned voltage distribution portion (131d) is made up of shunt resistance (Shunt Resistor).The size that can use first resistance (R1) to be about 10k ohm, second resistance (R2) is about the such resistance value of 2K ohm and differs the resistance about 5 times, so that voltage distribution becomes easy.For example, when input voltage is AC350V, can be designed to apply DC4.8V to control part (11).The power supply that distributes is applied to above-mentioned control part (11) through above-mentioned noise filter (131e).One end of above-mentioned noise filter (131e) is connected with first resistance (R1), second resistance (R2) and the diode (D16) of above-mentioned voltage distribution portion (131d), and the other end is connected with above-mentioned control part (11) one sides.
Above-mentioned noise filter (131e) is made up of the RC wave filter of the 3rd resistance (R3) and capacitor (C5), and its elimination is input to the noise in the voltage of above-mentioned control part (11), thereby can reduce the voltage detecting error that causes because of noise.
Control part (11) judges the RMS magnitude of voltage from the voltage signal of abnormal voltage test section (131) input, thereby judges whether the input power supply is unusual, and according to the power supply of this input part of cutting off the electricity supply (12).
Such abnormal voltage test section (131) is realized with circuit easily, and owing to be the insulated type design, so can therefore not detect the unusual of power supply easily because of surge (Surge) noise is burnt out, can be prevented that control part (11) is damaged because of surge noise.
Above-mentioned abnormal voltage test section (131) utilizes the input voltage of power input part (12), and predetermined big or small voltage signal is applied to control part (11).Then, control part (11) judges whether to be abnormal voltage, thereby optionally cuts off the electricity supply supply.
Specifically, according to the dc voltage value of measuring at the port of export of above-mentioned noise filter (131e), the ac voltage that will be input to above-mentioned power input part (12) tabulates (look-up table) and is stored in the storage part (19).For example, if the DC voltage of measuring at the port of export of noise filter (131e) is 4.8V, then to turn to the alternating voltage of being imported be that RMS voltage is equivalent to 350V to form.Therefore, can come the ac voltage of forecasting institute input, and the ac voltage of judging prediction is whether in the abnormal voltage scope according to the dc voltage value that detects at the port of export of above-mentioned noise filter (131e).
Fig. 4 shows the flow chart of control method of the air regulator of first embodiment of the invention, and Fig. 5 shows the control method of utilizing first embodiment of the invention is controlled the situation of driven compressor based on input voltage value chart.
With reference to Fig. 4; At start of run with input rated voltage as prerequisite, when the operating condition of user through above-mentioned input part (18) input indoor set, from above-mentioned control part (11) to the instruction of above-mentioned drive division (14) transmission driven compressor; Its result, the driving (S11) of beginning above-mentioned compressor (21).
Say at length from moment of driving of beginning above-mentioned compressor (21), whether above-mentioned abnormal voltage test section (131) detects in real time has the input of abnormal voltage (S12).The lower limit critical voltage (Vb) and the upper limit critical voltage (Vc) of the rated voltage that the voltage of importing through above-mentioned power input part (12) here, has the low-voltage (Va) and the high voltage (Vd) that are defined as abnormal voltage, be defined as stable state.
In more detail, above-mentioned input voltage has the relation of Va＜Vb＜Vc＜Vd.In addition; With the section definition between above-mentioned low-voltage (Va) and the lower limit critical voltage (Vb) is that the lower end lags behind interval (bottomhysteresis area) (C), is that the upper end lags behind interval (upper hysteresis area) (B) with the section definition between above-mentioned upper limit critical voltage (Vc) and the high voltage (Vd).In addition, the section definition between above-mentioned lower limit critical voltage (Vb) and the upper limit critical voltage (Vc) for can stably driving the stable region (A) of above-mentioned compressor (21), can be defined as the allowable voltage interval.In addition, above-mentioned low-voltage (Va) and high voltage are to be used to cut off the cut-out voltage (tripping voltage) that voltage is supplied with, and can be 182V and 281V respectively.In addition, above-mentioned upper limit critical voltage (Vc) can be 270V, and lower limit critical voltage (Vb) can be 190V.In addition, as above-mentioned, (Va～Vd) is the alternating voltage of predicting according to the dc voltage value that the port of export at the abnormal voltage test section detects (RMS voltage) to above-mentioned input voltage.
In addition, (B, under situation C), the operating condition of compressor (21) is constant to be positioned at above-mentioned hysteresis interval at input voltage value.In other words, under the driven state of compressor (21), (B, in the time of C), the driving of compressor (21) does not stop in above-mentioned hysteresis interval when input voltage value.On the contrary, under the state that compressor (21) has stopped, when above-mentioned input voltage value above-mentioned hysteresis interval (B, in the time of C), Driven Compressor (21) not.Of the back, the delay time that is used under the state that compressor stops, making its entry into service is from reaching the moment calculating of above-mentioned upper limit critical voltage (Vc) and lower limit critical voltage (Vb).
On the other hand,, then continue to keep driven compressor state (S13),, then judge from detected moment whether keep setting-up time (T1) (S14) if detect abnormal voltage if above-mentioned abnormal voltage test section (131) do not detect abnormal voltage.In addition,, then do not get into the abnormal voltage supply condition if do not pass through setting-up time (T1), and the state before continuing to keep.That is, keep driven compressor state (S13).In addition, if keep setting-up time (T1), stop Driven Compressor (S15).Here, above-mentioned setting-up time (T1) can be 1 second.
In order to drive again, from moment that compressor stops to drive need be through setting-up time (T2) at least.
At length say; Above-mentioned control part (11) judges from the moment that compressor stops to drive whether passed through setting-up time (T2) (S16), if process not then makes compressor continue to keep halted state (S17); If process judges then whether input voltage reaches the voltage in the stable region.Here, above-mentioned setting-up time (T2) can be 3 minutes.
Then, judge whether in setting-up time (T3), to keep and supply with (S18),, then make compressor keep halted state (S19) if do not keep setting-up time (T3) with the input voltage in the stable region.On the contrary, if be judged as and passed through setting-up time (T3), then be only limited to promptly not to be only limited under the situation of not sending the air regulator halt instruction and return to the step that compressor drives again under the situation of deenergization (20).Here, above-mentioned setting-up time (T3) can be 30 seconds.
On the other hand, above-mentioned setting-up time (T3) is variable, thereby guarantees the reliability of control algolithm.This is because according to the area that air regulator is set or national, the stability of the voltage of being supplied with has difference.Therefore, supply with unsettled area, above-mentioned setting-up time (T3) value is set at bigger, supply with stable area, can be set to less at voltage at voltage.
According to the chart of Fig. 5, following situation (a) has taken place: at the moment process setting-up time (T2) that stops to drive from compressor before, input voltage has been kept setting-up time (T3) at stable region.But, since after compressor stops through the setting-up time (T2) in delay time of being equivalent to be used for driving again, therefore ignore.This be because, under the state that compressor (21) stops Driven Compressor (21) again, must be through the after-applied power supply of preset time (T2), just can prevent that like this compressor is impaired.Therefore, after the moment that compressor (21) stops, with must through above-mentioned setting-up time (T2) as precondition, thereby can prevent that compressor is impaired.
Fig. 6 shows the flow chart of control method of the air regulator of second embodiment of the invention, and Fig. 7 shows the control method of utilizing second embodiment of the invention is controlled the situation of driven compressor based on input voltage value chart.
With reference to Fig. 6, present embodiment is characterised in that, stops the moment that drives for the first time at compressor; For the stable of compressor must be through the delay time (T2); And after stable region must pass through setting-up time (T3), compressor is driven again, when compressor stops afterwards; As long as satisfy in the condition of stable region, compressor driven again through setting-up time (T3).
At length say, when air regulator running instruction is transfused to, at first will be used for the accumulation variable (n) that number of times counts that stops of compressor is made as 0 (S21), and beginning Driven Compressor (S22).With above-mentioned first embodiment likewise, in the present embodiment also start of run with the input stable region alternating voltage as prerequisite.
Then, above-mentioned control part (11) judges whether to have supplied with abnormal voltage (S23) through power input part (12), according to its result, keeps the running (S24) of compressor or gets into the step of appending that is used to judge abnormal voltage.That is,, then judge whether in setting-up time (T1), to keep and supply with abnormal voltage (S25), thereby keep the running of compressor or stop driven compressor (S26) if detect abnormal voltage.
On the other hand, stop the condition of driven compressor and stopped driven compressor, then make the value of above-mentioned accumulation variable (n) increase by 1 (S27) if satisfy.Then, judge whether the value of accumulating variable (n) is 1 (S28).In other words, judge whether to stop for the first time Driven Compressor.Then, stop Driven Compressor (n=1) for the first time, then judge from compressor to stop constantly whether having passed through setting-up time (T2) (S29) if be judged as.In addition,, then keep the halted state (S30) of compressor,, then judge whether in setting-up time (T3), to have supplied with the voltage (S31) of stable region if passed through setting-up time (T2) if do not pass through setting-up time (T2).
At length say, if in setting-up time (T3), keep the supply burning voltage, judge whether that then air regulator running halt instruction is the input of power supply open command, if the input of the halt instruction of not turning round, Driven Compressor again then.On the contrary, if do not pass through setting-up time (T3), then continue to keep driven compressor halted state (S32).
