Description
The utility model relates to a kind of air conditioner distributor, especially a kind of indoor apparatus of air conditioner air conditioner distributor of refrigeration in turn of controlling.
So far as is known, real one drag two compressor of air conditioner generally is two kinds of forms, and the first is with the inverter compressor of fuzzy logic control, and it two is with the high-power compressor that can organize two Room refrigeration simultaneously.The former is owing to be high-tech product and artificial blockade, and we also do not have import in enormous quantities at present, and cost an arm and a leg.If the latter when only freezing to single chamber, still need start with all strength, low load with strong power, and many power consumptions power, price are also too expensive, make general middle-income user be difficult to accept.The principle of distributor, popular theory is exactly according to certain rules, open the triple valve (it is made up of two magnetic valves) of cold-producing medium by turns, carry the eighteenth of the twenty in the fluorine by turns for respectively two indoor sets, make two indoor sets refrigeration in turn, can the equilibrium of two Room lower the temperature, freeze by turns because be, used refrigerant amount and one-to-one are very nearly the same, and the coupling of refrigeration system can be brought into play maximum refrigerating efficiency when this had just guaranteed running.And as the distributor of the gloomy production in Guangdong east, use two transformers in the existing product, but it one takes up an area of with the space greatly, and two become very high at the device cost.And three minutes delay circuits before the startup of the compressor of existing distributor mostly are the timing of RC circuit, though simple, error is bigger.And compressor need be shut down the back in startup when two machines are changed.Because because compressor is when starting, surge current be compressor electric current when running well 5-7 doubly, and the moment of torsion that compressor bore is also than big many of normal operation moment of torsion, frequent starting and power consumption are too much and the minimizing compressor life-span like this.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of air conditioner distributor is provided, and it can open the triple valve of cold-producing medium by turns, and makes indoor set refrigeration in turn.When conversion, compressor is not shut down.
The purpose of this utility model is achieved in that a kind of air conditioner distributor, it is made up of compressor timing circuit, drive circuit and power circuit, its compressor timing circuit joins by timing signal change-over circuit and power circuit, A chamber signaling conversion circuit and B chamber signaling conversion circuit are delivered to the compressor timing circuit with switching signal, and deliver to conversion and interlock circuit; A machine timing circuit and B machine timing circuit are attempted by between meter inlet signal change-over circuit and conversion and the interlock circuit, and conversion and interlock circuit connect dynamo-electric magnet valve of A and the dynamo-electric magnet valve of B respectively.
The compressor timing circuit is a divider circuit.
A machine timing circuit connects subtract counter by frequency divider to be formed, and advances circuit during the B machine and connects subtract counter by frequency divider and form.
Conversion and interlock circuit are flip and flop generator.
The utlity model has following advantage:
1. compressor is at every turn by the delay time that all has two minutes and 44 seconds before the stopped status conversion operation state, during this magnetic valve have at least one the tunnel be out to guarantee the system pressure balance.
2. as long as there is one road signal to exist, compressor just can not shut down, and in handoff procedure, does not have the time-delay counting, in the service life of having improved compressor, shortens conversion time.
3. have only A, B signal disconnected entirely, compressor is just understood stall, if restart, two minutes 44 seconds delay times must be arranged also, and adopts merit frequency meter number, and the time is accurate.
4. the user of original one-to-one need not discard former one-to-one system, only need a distributor of configuration and an indoor set to get final product, so market potential is very big.
5. this device can match with the single cold type air-conditioning of the disposable type of any producer, and does not change any structure of former air-conditioning indoor unit and outdoor unit.
6. remove or change distributor, original system still can be by the unit refrigeration work, and is easy to use, safe.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a formation block diagram of the present utility model;
Fig. 2 is the utility model circuit theory diagrams.
Referring to Fig. 1-2, electric four bulks that are divided into of the present utility model:
Low-tension supply: because what adopt is compressor halt mode not when switching; therefore; an independently compressor power that breaks away from outside A, the B machine just must be arranged; this power supply should provide the alternating current 220V electric current of the motor-driven commentaries on classics of compression; also to provide logic circuit work+the 8V DC current so that control system still can operate as normal when A, B machine switch.
Low-tension supply is made up of D3, D4, D5, D6, D14, R8,7808, C1, C2, C3, C4, transformer output～13V arrives～14V, rectifier bridge through D3, D4, D5, D6 composition, be input to 1 pin of three terminal regulator 7808, by 3 pin output+8V DC current voltages, for each power supply of integrated, reach the signal conversion usefulness of A, B machine, C1, C2, C3, C4 are that filtering is used.R8 is a current-limiting resistance, can prevent the too high voltages of bridge output, all falls on voltage-stablizer, causes the voltage-stablizer heating, in addition, about the voltage output+14V of bridge, uses as the conducting voltage of drive system relay.
The signal conversion is respectively timing signal and A, B indoor set refrigeration require signal.D8, D13, R24, IC13, R23, C5 and D9, D12, R25, IC14 are two photoelectrical couplers among Fig. 2, in case this circuit incoming call, then light emitting diode is controlled phototriode in the coupler, E, the C that makes triode be extremely full to close conducting, low-voltage DC is exported from E pin (4 pin) through the C pin, pass through capacitor filtering again, promptly can be used as the substitution signal of A, B machine～220V signal, participate in logic control.
Timing and logic control are the cores of allotter circuit, are overlapped by timing and control logic two parts, combine.
Timing: this device has two times to need timing: protection in three minutes and 15 minutes refrigeration.Timer is made up of frequency divider 4060 sum counters 4510 respectively.4060 can directly receive rising or the milder impulse wave of the trailing edge ratio of slope, and it has 2
4～21
4Between ten kinds of frequency divisions, be output as each cycle elder generation's output low level of 1: 1 square wave, back output high level.Therefore, in timing in three minutes, be set at 2
14=16384 frequency divisions; cycle is 60 seconds ≈ of (16384HZ ÷ 50HZ) ÷ 5.46 minutes; get the preceding half period; it is low level; then immediately with analog switch 4066 close input and make it no longer count to being upgraded to high level later half Monday, and like this, output just forever keeps high level control compressor operating; the time of this half cycle is that 5.46 ÷ 2=2 divided 44 seconds, that is to say that the guard time of setting compressor is 2 minutes and 44 seconds.And 15 minutes refrigeration: owing to need the overall pulse number too many, only depend on 4060 to be difficult to a frequency division and to put in place, therefore adopt the frequency division mode that combines with counting, setting 4060 is 2
13=8192 frequency divisions, and 4510, set the subtraction form for, give installing and be decided to be 6, because 4510 be that rising edge works, so it becomes 5 o'clock actual just half square waves (low level stage) by 6, so 4510 reduce to zero by 6, middle shared 5.5 square waves of 4060 outputs, its time is 60 seconds ≈ of (8192HZ * 5.5) ÷ 50HZ ÷ 15 minutes and 1 second.
Control logic circuit should be achieved as follows logic function.Wherein low level is represented with " 0 ".High level is represented with " 1 ".Suppose A machine signal first now, the B machine is signal afterwards.This device " powers on ", but A, B machine all do not start: a=0 b=0, C=1 then, be the clear terminal of three minutes delayers of IC24060: 12 pin=1 is in cleared condition, so d=0 l=1 is (though it makes the count pulse input, so but export still d=0 owing to be in zero clearing), then cause f=0.As a result, compressor relay " N1 " disconnects, and compressor stops, again because of f=0, thus g=1, r=1.Solenoid relay valve N2, N3 connect, but because of two magnetic valves by A, B～power supply of 220V holding wire, A, B no signal now, promptly A, B do not have electricity, so yet closure all of A, B magnetic valve.On the other hand, a=0, b=0, g=1 then, h=1, two-way 4510 is in cleared condition, i=0, l=0, k=1, n=1 make 4060 frequency divider IC7, IC8 also be in cleared condition, not output, and simultaneously j=1, m=1 make 4510 constantly to be in and to prepare to put number state again, and master slave system was in SBR in 15 minutes.Compressor does not turn round, and A, B magnetic valve are all closed.
A B machine successively all comes signal, (establishing a-signal earlier) a=1, and c=0 then, the IC2 zero clearing finishes to enter three minutes time-delay states.But owing to export preceding half cycle--the low level of square wave earlier, thus d=0, l=1 (guaranteeing that pulse continues by analog switch IC3), so f=0 ends 9013 of N1, compressor does not start.While g=1, r=1, because a-signal has come, so A valve N2 opens, air-conditioning enters the pressure balance stage, the B valve does not arrive because of signal, still closes.Because a=1, so g=0, A road counter 4510IC11 enters the count enable state; but because d=0 then C, the D double switch of IC3 all close, so 4510 still do not count i=1 just in the protection in three minutes; j=0 (put count up to complete), since b=0, l=0; n=1, so k=0, then K=0 has blocked 1 of B road; even 1 comes signal again, remain n=1, and k=0; n=1 finishes the IC7 zero clearing of A road, and the frequency divider IC8 on B road still is in zero clearing.Subsequent s=0, P=1.If the B signal arrives subsequently, B=1 then, but it does not have influence to C, unless a=0 in during 2 minutes and 44 seconds, at this moment b can make C still equal 0, makes timing in three minutes unaffected, after the B signal arrives, b=1, h=0,4510 zero clearings on B road finish, l=1, M=0 gives putting to count also and finishes, but, sealed the path on B road, so n=1 still because of K=0,4510 countless counting make the frequency divider on B road still locate the zero clearing stage, so can only be in wait state.Unique variation is that the B signal has come, and the B magnetic valve is opened, and has accelerated the process of system pressure balance.
At three minutes guard periods, compressor did not change, and magnetic valve is opened, and A, B all do not have timing in 15 minutes, but the path of controlling oneself has been opened on the A road, and the B road is in wait state.
D=1 after 2 minutes 44 seconds, l=0 (closes analog switch, count pulse must not be entered, stop counting, but still be in low level because of 12 pin, it is non-cleared condition, so d=1 promptly equals " 1 " forever at press run duration d), so f=1 makes 9013 saturation conductions on N1 road, then N1 is logical, compressor start.Simultaneously, because f=1, P=1 is r=0 then, and then the B valve cuts out, so simultaneously because of S=0 q=1, the A valve is still opened.In addition, because the d=1 C of IC3 then, the D way switch is opened, the 4060 beginning frequency divisions on A road, and the B route is in cleared condition in 4060, so not-time.
Compress motor-driven commentaries on classics, the A opening of valves, the B valve cuts out, and the A road begins kind timing in 15 fens, and system gives A chamber refrigeration.Because the subtracter 4510 (IC11) on A road is reduced to " 0 " then extremely short undersuing of 7 pin output, it makes j generation moment positive pulse, finished 4510 give again and put several work and partly enter the wait count status, main is that this negative pulse makes k=1, decontroled blockade, two kinds of situations, first have been arranged this moment: if the B signal is established shutoff the B road, still waiting for, be l=1, then n=0 is returned to i=1 even blocked A road i conversely, also can't make K equal " 0 ", then form k=1, the stable state of n=0, K=1 makes 4060 zero clearings on A road, n=0 makes the 4060 beginning frequency divisions on B road, makes the B road enter 15 minutes time status.The A road is in the wait state that is blocked, while s=1, and g=0, end on 9013 of A road, and the A valve cuts out.Because b=1, k=1, thus p=0, r=1 then, 9013 conductings on B road, the B opening of valves, then system begins to freeze to the B chamber.Second: if the A road is at 15 minutes 01 seconds constantly, the B opening of valves, B does not open on the road, or the then l=0 that shut down, though this moment k=1, n=1 controls oneself and has blocked the B road, still n=1, so just can't block the A road, then the negative pulse as i finishes, when becoming high potential i=1, still k=1, n=1, s=0, p=1, q=1, r=0 promptly remains the A valve and opens, and the B valve closes, still give A chamber refrigeration, just, put to give for 4510 of A again and put number, begun 15 minutes 01 seconds timing of a new round because the moment positive pulse appears in j.Even send a telegram here immediately in the B road, have to wait until that also the switching machine at 15 fen 01 second a moment has been understood next time.
If all there is the refrigeration requirement two Room, then elder generation gives the refrigeration earlier of signal, and switching instant must be waited until to signal in the back, if do not freeze and require signal in another chamber, but A chamber separate refrigeration was then searched for the other side once in per 15 minutes 01 seconds, there is requirement just to switch in the past as the other side, as the other side's no requirement (NR), then still from refrigeration.Because A, B signal have an existence at least in 15 fens switching processes, so the output of timing in three minutes is high potential forever, promptly compressor is not shut down in the handoff procedure.If the A machine is on-stream, a-signal break suddenly (shutdown or A chamber have reached to give and have put temperature) at this moment two kinds of situations are arranged:
The B signal is in wait state, and a=0, but b=1, c=0 then, IC2R12 pin still can not zero clearings, so d=1, l=0, the f=1 press does not stop, and a=0 g=1 then makes 9 pin on A road 4510 equal " 1 " in addition, then this 4510 zero clearing, l=0 is k=1 then, so because l=1 is n=0, then be directed at s=1.Because f=1 event q=0, the A valve cuts out.K=1 b=0 is p=0 then, r=1 then, and the B opening of valves changes B chamber refrigeration immediately over to, even subsequently because of temperature recovery, make a=1, i=1 will wait for that also switch 15 fens 01 second that times of L again.
If the B signal also breaks, and (the B machine shut down or the B chamber also reached to give put temperature).A=0, b=0, c=1,12 pin of IC2 equal " 1 ", and 4060 are in cleared condition, d-0, l=1, f=0, compressor stall q=1, r=1, so but all open because of no A, B signal A, B valve, entire circuit has been got back to " though distributor powers on A, B machine all not starting state " just might A, if the B machine all is in shape that startup reaches temperature really after this because of any reason starts, owing to three minutes timers zero clearing, all again after the timing in three minutes, compressor could start.
A, B chamber signal all do not have, and then press then stall, and closed electromagnetic valve restarts again, the time-delay of three fens kinds also must be arranged after, compressor could start.
Drive and executive circuit: mainly by three 9013 switch triodes, three relays, and corresponding resistance, diode is formed, simple on-off circuit, by+13V～+ 14V low-tension supply driving relay, connection～220V circuit, the power supply of off-premises station is supplied with by the distributor power supply, can't help indoor set to supply with, indoor set～the 220V signal is only as signal source and solenoid valve, it has avoided common one drag two off-premises station to be powered by two indoor sets, but because in case fire, zero line intersection wrong, and cause risk of short-circuits, this danger disorderly connects the slotting box of power supply for the user who is ignorant of electricity and is easy to occur, this distributor mode of connection then can allow the user arbitrarily arrange the fire of power pack, zero line position, or random power supply inserting plug do not have risk of short-circuits extremely, the security of system and user's Personal Safety have been increased.
