Description
The present invention relates to the quilt that is provided with indoor units (indoor set) is transferred the indoor air conditioner that carries out air conditioning.
Air conditioner (below be called " air conditioner ") be by will by through being arranged on the heat exchanger of being transferred indoor indoor set (indoor units) carried out thermoregulator air be blown out to transferred indoor, thereby transferred the indoor machine that carries out air conditioning.
For such air conditioner, by on the remote control switch of the operation that carries out thermoregulator, temperature sensor being set, the line space of going forward side by side regulation and control system is accomplished to make to be in and is transferred indoor people's temperature on every side to become design temperature so that make the temperature that is mainly detected by this temperature sensor (being arranged on the temperature sensor on the remotely monitored sensor) become design temperature.That is, remote control switch is transferred indoor people to operate by being in, and the temperature of this remote control switch is near being in the sendible temperature of being transferred indoor people.Therefore, by being set at design temperature by the temperature that remote control switch detected, making the people feel to be transferred indoor is comfortable air-conditioning state.
But the installation site of the indoor units of air conditioner preferably can thus, just can make indoor whole zone become comfortable air-conditioning state towards being transferred indoor Zone Full to blow out the position of air-conditioning wind.
In recent years, the area of being transferred the chamber that is carried out air conditioning by air conditioner enlarged, and in addition, was formed L word shape etc. by the chamber of accent, and its shape is variation also.On the other hand, the installation seated position of indoor units often needs to avoid window, door and room beam etc. to be restricted.Therefore, for indoor four corner being carried out air conditioning equably, need the strong thermoregulator of air-conditioning ability with 1 indoor set.
But,, the indoor gamut of being transferred of spaciousness is carried out that air-conditioning is unsatisfactory equably from energy-conservation viewpoint.That is, even transferred indoor spaciousness, often the residing space of people is limited, and the result transfers indoor four corner to carry out air-conditioning to the quilt of spaciousness and just makes nobody's space also spread all over the air that has carried out the temperature air-conditioning, correspondingly, produced the necessity that improves the air-conditioning ability.
Energy-conservation situation when considering such air conditioning wishes that emphasis carries out air-conditioning to the space that the people stopped.For this reason, indoor units is set to air-conditioning is carried out in the longest zone of people's time of staying.
But, indoor units is being installed when making in spaciousness indoor mainly that air conditioning is carried out in long zone to people's time of staying, indoor units be not in the position that can spread all over the indoor whole zone of spaciousness (for example middle body) but should be towards the long-time zone that stops of people (or often the zone that stops of someone) install.
On the other hand,, be necessary sometimes by indoor units (indoor set) that perhaps air conditioning is carried out in the zone beyond the zone that indoor units is faced to the whole indoor air conditioning of carrying out even under the situation that is provided with indoor units like this.At this moment, even with only the same operation of air conditioner that carries out of air conditioning is carried out in the zone that normally people stopped, since indoor units place skew is set, the zone beyond spaciousness whole indoor often can not make the zone of mainly being carried out air-conditioning by indoor units certainly becomes comfortable temperature.
That is, the indoor temperature during air conditioning has been used the temperature sensor that is arranged on indoor set or has been arranged on temperature sensor on the remote control switch.In addition, because indoor units is set at the long zone of time that the people stops, therefore, the air conditioning efficient height that this is regional, and owing to depart from this regional air-conditioner efficiency step-down, even, also be difficult to air conditioning is equably carried out in desirable zone so only use is carried out air conditioning with the temperature of the temperature sensor detection of remote control switch.
For this reason, people consider and are being transferred a plurality of temperature sensors of indoor configuration, according to the detected temperatures control air-conditioning ability of separately temperature sensor.
But, even in the temperature of measuring 2 different zones of air-conditioner efficiency, carry out air conditioning, if the air-conditioner efficiency difference also is difficult to make the air-conditioning state even, for example, owing to the place difference, often the zone because of chillout produces sticky feeling with the sufficient zone of heating when heating.
The present invention proposes in view of the above fact, it is a kind of when when being transferred a plurality of temperature sensor of indoor configuration that its purpose is to provide, and makes air conditioning respond well and make the zone that has disposed temperature sensor separately become the air conditioner of comfortable air-conditioning state.

In view of the above, owing to can use the temperature revised and any one room temperature control air-conditioning ability of two room temperatures, thereby can use well-known in the past control method.In addition, can control a side who wishes to make the gentle concubine temperature in main chamber makes the opposing party's room temperature lentamente near design temperature near design temperature the time.
Second aspect present invention is characterised in that it comprises the correction restraint device that the correction by the described design temperature that described correcting device produced is limited in specified scope.
According to the present invention, the correction when design temperature is revised in restriction.For example, if because the temperature height of the gentle concubine temperature in main chamber, and make the correction quantitative change of design temperature big, and then often not reaching design temperature a side, the opposing party surpasses design temperature widely, and the temperature difference strengthens all the more.
To this, by the correction of limit setting temperature, just can prevent between the gentle concubine temperature in main chamber, to produce the big temperature difference, simultaneously, for design temperature, a side who suppresses the gentle concubine temperature in main chamber becomes too high, or low excessively, makes high efficiency air-conditioning become possibility.
Third aspect present invention is characterised in that, it comprises the storage device of the variation resume of storing described concubine temperature, and according to the prediction unit of being predicted described concubine temperature by the variation resume of described memory device stores, described correcting device is revised described design temperature according to the concubine gentleness of being predicted by described prediction unit by main chamber's temperature that described main temperature checkout gear is detected.
According to the present invention, can store the resume of the concubine temperature that secondary temperature-detecting device detects, and after the variation of the resume prediction concubine temperature of being stored, revise design temperature.Usually, the timing that detects each temperature of a plurality of temperature-detecting devices is often different.If regularly different, the temperature difference will be different with the actual temperature difference.For this reason, the concubine temperature when predicting detection main chamber temperature by the resume of the concubine temperature from be stored in storage device just can prevent that the difference of the gentle concubine temperature in actual main chamber from having big difference, and suitably revise design temperature.

Sub remote controller 140 is switched on operation by power switch 160, carry out the people's of the mensuration of room temperature of temperature detection part 142 and people's probe portion 144 the detection that has or not, and in people's probe portion 144, survey in the people, the temperature of sending at a certain time interval to be measured is sent simultaneously by the position position signalling that switch 146 sets is set.
On the other hand, the position that the microcomputer 74 of indoor units 12 passes through from the set positions signal determining sub remote controller 140 of sub remote controller 140, swing left and right sides wind direction baffle plate 52 is so that produce by boasting from the air-conditioning wind of blow-off outlet 50 to this position.In addition, if stop just to stop the swing of this left and right sides wind direction baffle plate 52, and begin the swing of left and right sides wind direction baffle plate 52 once more by the signal that input has detected the people from the microcomputer 74 that sub remote controller 140 has detected people's signal indoor units 12.At this moment, when the body sense button 128 of having operated master remote controller 120 was sensing mode, microcomputer just used the temperature and the air quantity of the room temperature control air-conditioning wind of being sent by sub remote controller 140.
As shown in Figure 10, the indoor units 12 of air conditioner 10 is installed into usually to the main region 162A in the chamber 162 that transferred that carries out air-conditioning and blows out air-conditioning wind.That is, indoor units 12, positive towards being transferred indoor main region to be mounted, usually, being turned round makes this main region become comfortable air-conditioning state.
Sub remote controller 140 is installed in to be wanted transferred the position different with main region 162A in the chamber 162 to carry out the zone of air-conditioning (below be called subregion 162B)
As shown in Figure 9, air conditioner 10 makes the direction of the air-conditioning wind that is blown out by left and right sides wind direction baffle plate 52 make the front of indoor units 12 become original position (below be called original position C) usually, and left and right sides wind direction baffle plate 52 is being that the center is Q with this original position C
0(scope with 50 ° is for example swung) can be swung in the scope left side of angle.In addition, when the set positions switch 146 of sub remote controller 140 be set in " in " time, left and right sides wind direction baffle plate 52 is that swing at the center with this original position C equally.
On the other hand, if the set positions switch 146 of sub remote controller 140 is set at " left side " or " right side ", then the original position R of indoor units 12, L change over angle Q respectively
u, Q
1, and respectively about with angle Q
1The scope of (for example about 30 °) is swung.That is, the set positions switch 146 of the swing of left and right sides wind direction baffle plate 52 by sub remote controller 140 to the right or left avertence move.
In addition, when making 52 swings of left and right sides wind direction baffle plate by the signal from sub remote controller 140, the air quantity that increase blows out from blow-off outlet 50 etc. will make air-conditioning wind positively reach the subregion 162B shown in the sub remote controller 140.
On the other hand, if the body sense button 128 of master remote controller 120 is operated, be arranged on the microcomputer 74 in the indoor units 12, just, carry out being transferred the air conditioning in the chamber 162 according to the room temperature that detects by master remote controller 120 and by room temperature and design temperature control air-conditioning ability that sub remote controller 140 detects.In addition, the storage at room temperature that detects and send by sub remote controller 140 in not shown memory, when reading in the room temperature that detects by master remote controller 120, just predict the temperature around the sub remote controller 140 at every turn, according to the difference correction design temperature of the room temperature that is detected by master remote controller 120.
At this moment, for the correction quantitative change that prevents design temperature is big, the correction of design temperature is limited in setting, and (for example some degree are in 1 degree (1 ℃) as an example in this example.
The below effect of this example of explanation.
If the switching manipulation by master remote controller 120 in air conditioner 10 forms the running/shut-down operation that is set at any state such as cooling operation, dehumidifying running and the warm running of system, then begin the running of the drive manner that sets.
If running operation is formed and begins operation of air conditioner, air conditioner 10 is just measured design temperature and indoor temperature, and according to this measurement result, the operating frequency of setting compressor 26, air quantity (revolution of cross flow fan) etc. carry out the air conditioning running according to this setting result.
In addition, in outdoor unit 14, switch cross valve 24 according to the drive manner that sets.For example, if be set at refrigeration or dehumidification mode, then just be supplied to the heat exchanger 30 of outdoor unit 14 by compressor 26 refrigerant compressed.Therefore, owing to be liquefied by heat exchanger 30, this cold-producing medium that has liquefied is supplied to the heat exchanger 18 of indoor units 12 by compressor 26 refrigerant compressed.The cold-producing medium that is fed into the heat exchanger 18 of indoor units 12 is gasified by heat exchanger 18 time, makes the air cooling by heat exchanger 18.
On the other hand, when the warm running of system, switch cross valve 24 so that make the high-pressure refrigerant that is compressed by compressor 26 supply to the heat exchanger 18 of indoor units.Thus, when compressed high-pressure refrigerant was liquefied in heat exchanger 18 in compressor 26, heating was by the air of heat exchanger 18.By blowing out this heat exchanger 18 heated air and make indoor warm to indoor by system from blow-off outlet 50.
But, in air conditioner 10, usually, measure indoor temperature by the temperature sensor 84 of indoor units 12, if the body sense button 128 of operation master remote controller 120 is just to have used the room temperature of measuring with temperature sensor 84 to add that the body sensing mode of the room temperature of being measured by master remote controller 120 turns round.At this moment, be opened at sub remote controller 140, and when being received in the room temperature of measuring in the temperature detection part 142 of sub remote controller 140, will turn round with the many body sensing modes that carry out operation of air conditioner according to the room temperature that temperature sensor 84, master remote controller 120 and sub remote controller 140 are detected separately.In addition, may be performed during the automatic running of wind direction such as body sensing mode, dehumidifying warm and air quantity in automatic setting refrigeration, system.
In Figure 11, the summary action that shows sub remote controller 140 is in this sub remote controller 140, by making operation power switch 160, begin the room temperature around the sub remote controller 140 when carrying out instrumentation, is carried out people's the detection that has or not by people's acquisition sensor 152 by temperature detection part 142.
About people's the detection that has or not, if people's acquisition sensor 152 is not connected in exceed schedule time (for example 15 minutes), just be set at nobody, even interrupted, detect the people continuously with interior people's acquisition sensor 152 at the appointed time, also be set at the people.
On the other hand, such shown in the flow chart of Figure 11, by connecting the operation of power switch 160, sub remote controller 140 is sent the room temperature of being measured in temperature detection part 142 in the set condition of sending set positions switch 146 in initial step 200.Meanwhile, the instrumentation that in next procedure 202, resets/start is used to send the timer in the time interval of signal.
In next step 204, whether affirmation reaches the stipulated time by the time of timer instrumentation, when having reached the stipulated time, (in step 204, be judgement certainly) and just transfer to step 206, and people's probe portion 144 confirms whether to be judged to be people's (being set at the people).
If be judged to be man-hour, transfer to step 200 after the judgement of then in step 206, answering affirmatively herein.Thus, at each official hour (time t for example at interval
2Be about 10 minutes) in, by sub remote controller 140 send it around room temperature.
In addition, when being set at nobody (in step 206 judgement of answering in the negative answer), people's probe portion 144 is before the people who surveys around the sub remote controller 140, be in holding state, since detected the people, the judgement of in step 200, answering affirmatively, and restart to carry out this flow chart.
On the other hand, by the signal that is shifted to body sensing mode by master remote controller 120 inputs, air conditioner 10 is carried out the body sensing mode (many body sensing modes) that has used the room temperature that is detected by master remote controller 120 and sub remote controller 140.At this moment,, revise design temperature, carried out air conditioning according to the design temperature of being revised to transferring in the chamber 162 again according to by the room temperature of master remote controller 120 detections and the room temperature that detects by sub remote controller 140.In addition, by from sub remote controller 140 input position setting signals (signal of the mode of operation of correspondence position configuration switch 146), the initial position that indoor units 12 is set left and right sides wind direction baffle plates 52 carries out the swing corresponding to this initial position.Moreover, when body sensing mode finishes, when perhaps the action of sub remote controller 140 stops (having stopped sending of temperature signal etc.), will turn back to the initial position of left and right sides wind direction baffle plate 52, and carry out the air conditioning of main region 162A.
Master remote controller 120 accomplish to send by sub remote controller 140 and in the time interval detected room temperature, the microcomputer of indoor units 12 is stored the room temperature of sending from sub remote controller 140 successively, whenever reads in the room temperature T that sends from master remote controller 120
Rtp, just predict current room temperature T from the room temperature of storage
Rts
In addition, suppose that it is time t that sub remote controller 140 is sent the time interval of room temperature
2(for example about 10 minutes a little bit poorer), the time interval that master remote controller 120 is sent room temperature is time t
1(for example 5 minutes more).In addition, the sending of the room temperature by stopping sub remote controller 140, correction that will the end setup temperature.At this moment, just turn back to the initial position of left and right sides wind direction baffle plate 52, and blow out air-conditioning wind to main region 162A.
In Figure 12, the correction overview of design temperature is shown according to the room temperature that is detected by master remote controller 120 and sub remote controller 140.This flow chart is by being set at body sensing mode, and sends out from the room temperature of master remote controller 120 and sub remote controller 140 and be performed.

Rtp
Meanwhile, in step 214, the room temperature that prediction is detected by sub remote controller 140.
One example of the prediction of the room temperature that detects by sub remote controller 140 shown in Figure 13.Send the room temperature signal from sub remote controller 140 at every turn, just read in the room temperature T that sends from sub remote controller 140
Rts, store 2 times nearest room temperature T
Rts1, T
Rts2, the current room temperature T of the prediction of the elapsed time when reading in room temperature at last
Rtt
In the initial step 220 of this flow chart, confirm whether to have received the room temperature signal of sending from sub remote controller 140, when judging certainly, read in T under the room temperature that is sent after transferring to step 222
RtsAfterwards, to room temperature T
Rts1, T
