Air conditioner 10 continues operation of air conditioner, and has turned into a part of air conditioner in the air conditioner 10 for the machine that stops or all empty
Tune machine then starts again at carry out operation of air conditioner.Specifically, control unit 23 is according to the sequence of operation predetermined, from more skies
Turn into the air conditioner 10 selected in the air conditioner 10 for the machine that stops as conveyer in tune machine 10.It has been selected as the air-conditioning of conveyer
Machine 10 starts again at carry out operation of air conditioner.
(step ST16)
Then, control unit 23 to from start transition operation when count whether have passed through the pre-set transition operation time
T2 is judged.Specifically, control unit 23 1 is selected in step ST15 begins to calculate as the air conditioner 10 of conveyer
Elapsed time, and whether transition operation time T2 has been reached to the elapsed time and has been judged.When have passed through transition operation
Between T2 when be put into step ST13.
By the way that above-mentioned processing is repeated so that a part of air conditioner in more air conditioners 10 stops successively.Moreover, work as
When end operation (to indicate to terminate the operation operated in turn) in turn has been carried out to the operating portion 22 of remote control 20, remote control 20
Control unit 23 more air conditioners 10 are all just elected to be conveyer, and terminate to perform the processing operated in turn.Such one
Come, operating in turn will terminate.
The specific example ＞ that ＜ is operated in turn
Then, reference picture 4 is specifically described to operating in turn.In this example, in the case where a part stops operating from the
An air conditioner 10 is selected in one~the 3rd air conditioner 10a~10c as the machine that stops, so that being opened from the first air conditioner 10a
A tableland begin successively as the machine that stops.Under initial operation, the first~the 3rd air conditioner 10a~10c is all selected as operating
Machine.
As due in t0, the operating portion 22 of remote control 20 is started to operate in turn, so as to which the first~the 3rd is empty
Tune machine 10a~10c all turns into conveyer.For example, the control unit 23 of remote control 20 is to the first~the 3rd air conditioner 10a~10c
All send releasing instruction of stopping.Thus, under initial operation, just room air is adjusted by three air conditioner 10a~10c
Section.
Then, as due in t1 after have passed through initial operation time T0, from as the first~the 3rd of conveyer the
The first air conditioner 10a is selected in air conditioner 10a~10c as the machine that stops.For example, control unit 23 is sent to the first air conditioner 10a
Stop instruction.Thus, in the case where a first time part stops operating, just by two air conditioners in addition to the first air conditioner 10a
Room air is adjusted by 10b, 10c.
Then, as due in t2 after have passed through a part of stop time T1, it has also become the first air conditioner of the machine that stops
10a is just selected as conveyer.For example, control unit 23 sends releasing instruction of stopping to the first air conditioner 10a.Thus, for the first time
Under transition operation, next predetermined the second air conditioner 10b that turn into the machine that stops continues operation of air conditioner, and turns into and stop
Only the first air conditioner 10a of machine then starts again at carry out operation of air conditioner.3rd air conditioner 10c also continues with operation of air conditioner.Cause
This, room air is adjusted by three air conditioner 10a~10c.
Then, as due in t3 after have passed through transition operation time T2, from as the first~the 3rd of conveyer the
The second air conditioner 10b is selected in air conditioner 10a~10c as the machine that stops.Thus, stop in second of part under operating, just
Room air is adjusted by two air conditioners 10a, 10c in addition to the second air conditioner 10b.
Then, as due in t4 after have passed through a part of stop time T1, it has also become the second air conditioner of the machine that stops
10b is just selected as conveyer.Thus, under second of transition operation, next make a reservation for turn into the 3rd air conditioner of the machine that stops
10c continues operation of air conditioner, and the second air conditioner 10b for having turned into the machine that stops then starts again at carry out operation of air conditioner.The
One air conditioner 10a also continues with operation of air conditioner.Therefore, room air is adjusted by three air conditioner 10a~10c.
Then, as due in t5 after have passed through transition operation time T2, from as the first~the 3rd of conveyer the
The 3rd air conditioner 10c is selected in air conditioner 10a~10c as the machine that stops.Thus, stop in a third time part under operating, just
Room air is adjusted by two air conditioners 10a, 10b in addition to the 3rd air conditioner 10c.
Then, as due in t6 after have passed through a part of stop time T1, it has also become the 3rd air conditioner of the machine that stops
10c is just selected as conveyer.Thus, under third time transition operation, next make a reservation for turn into the first air conditioner of the machine that stops
10a continues operation of air conditioner, and the 3rd air conditioner 10c for having turned into the machine that stops then starts again at carry out operation of air conditioner.The
Two air conditioner 10b also continue with operation of air conditioner.Therefore, room air is adjusted by three air conditioner 10a~10c.
Then, as due in t7 after have passed through transition operation time T2, from as the first~the 3rd of conveyer the
The first air conditioner 10a is selected in air conditioner 10a~10c again as the machine that stops.Thus, stop operating in the 4th part
Under, just room air is adjusted by two air conditioners 10b, 10c in addition to the first air conditioner 10a.
As described above, by allowing a part of air conditioner in more air conditioners 10 to stop successively, and more air-conditionings can be made
The duration of runs of machine 10 realizes equalization.Also by carrying out initial operation during the beginning operated in turn, and it can suppress empty
The air conditioning capacity of adjusting system 1 declines during the beginning operated in turn.And then by stopping fortune in a part in the case where operating in turn
Turn between carry out transition operation, so as to by turn into stop machine air conditioner 10 from machine-cut of stopping change into conveyer it
Afterwards, then by the next predetermined air conditioner 10 that turn into the machine that stops the machine that stops is switched to from conveyer.Thereby, it is possible to by by sky
Everything air conditioning capacity for bringing suppression air-conditioning system 1 that tune machine 10 changes conveyer into from machine-cut of stopping declines.
＜ human testings control ＞
Then, reference picture 5 illustrates to human testing control.When the operating portion 22 to remote control 20 has carried out people's physical examination
When survey starts operation (to indicate to start the operation of human testing control), air-conditioning system 1 just carries out following processing.Need to illustrate
, following processing are the processing that each indoor set 12 is individually carried out.That is, it is arranged on the first air conditioner 10a interior
Room control unit 42 in machine 12 carries out the dynamic of step ST21~step ST23 according to the first human body detection sensor 51a output
Make.Second air conditioner 10b and the 3rd air conditioner 10c are also same.
(step ST21)
First, room control unit 42 is to detect people indoors or examine to the human body detection sensor 51 of indoor set 12
People is measured indoors not judged.When human body detection sensor 51 detects people indoors, step ST22 is put into.It is another
Aspect, when human body detection sensor 51 detects people not indoors, then into step ST23.
(step ST22)
When human body detection sensor 51 detects people indoors, room control unit 42, which just allows, is provided with human testing biography
The air conditioner 10 of sensor 51 carries out operation of air conditioner.Thus, the air conditioner 10 that someone around be present just carries out operation of air conditioner.Need
It is bright, for the air conditioner 10 for the machine that is selected as stopping because operating in turn, even if the human testing sensing of the air conditioner 10
Device 51 detects people indoors, and the air conditioner 10 will not also be selected as conveyer.Hereafter, it is again introduced into step ST21.
(step ST23)
On the other hand, when human body detection sensor 51 detects people not indoors, room control unit 42 is carried out not existing
When act.That is, room control unit 42 will be provided with the air-conditioning for detecting the human body detection sensor 51 of people not indoors
Machine 10 is elected to be the machine that stops.Thus, the air conditioner 10 of surrounding nobody is maintained for dormant state.Hereafter, it is again introduced into step ST21.
By the way that processing as described above is repeated, so as to according to people whether indoors, to switch air conditioner 10
Operating condition.Also, when the operating portion 22 to remote control 20 has carried out human testing end operation (to indicate to terminate people's physical examination
The operation of observing and controlling) when, human testing control will terminate.
The specific example ＞ of ＜ human testings control
Then, human testing control is specifically described by reference picture 6 and Fig. 7.In this example, above-mentioned wheel is being carried out
Flow and human testing control is carried out in the air-conditioning system 1 of operating.Moreover, can perform with stop comprising not when the human body that acts
Switched between detection control.Here, after first being illustrated to the situation (reference picture 6) of executor's physical examination observing and controlling, then it is right
The situation (reference picture 7) for stopping human testing control illustrates.
(when executor's physical examination observing and controlling)
As shown in fig. 6, as due in t0, operation and human body are just started in turn to the operating portion 22 of remote control 20
Detection starts to operate.Then, just start it is above-mentioned operate in turn, pedestrian's physical examination observing and controlling system of going forward side by side.That is, when human testing passes
When sensor 51 detects people not indoors, just turn into be able to carry out not when the state that acts.
During this section untill moment t0 to moment t8, first~third party body detecting sensor 51a~51c is examined
Measure people indoors, thus the first~the 3rd air conditioner 10a~10c all without because perform not when action and be in the shape that stops
State.Therefore, during this section untill moment t0 to moment t8, the first~the 3rd air conditioner 10a~10c operating condition meeting
Switched because being operated in turn.
Then, for example, as due in t8 after have passed through the stipulated time, third party's body detecting sensor 51c is detected
People is not indoors.Now, in the case where operating in turn, the 3rd air conditioner 10c has been selected as conveyer.In contrast, in moment t8,
Three air conditioner 10c can because perform not when action operation of air conditioner is stopped.Moreover, in moment t8, in the case where operating in turn, first
Air conditioner 10a is selected as conveyer, and the second air conditioner 10b is selected as the machine that stops.Therefore, merely with three air conditioner 10a~10c
In the first air conditioner 10a room air is adjusted.
Then, as due in t9 after have passed through the stipulated time, third party's body detecting sensor 51c detects people again
Indoors.Then, just without not when act, the 3rd air conditioner 10c is just selected as conveyer again.Thus, the 3rd air-conditioning
Machine 10c carries out operation of air conditioner.Moreover, in moment t9, in the case where operating in turn, the first air conditioner 10a is selected as conveyer, and second is empty
Tune machine 10b is selected as the machine that stops.Therefore, using two air conditioners 10a, 10c in addition to the second air conditioner 10b to Interior Space
Gas is adjusted.
Here, during this section untill moment t1 to moment t2, the first air conditioner 10a is selected as in the case where operating in turn
Stop machine.On the other hand, the first air conditioner 10a the first human body detection sensor 51a detects people indoors in same period.
Under these conditions, the first air conditioner 10a makes operation of air conditioner stop in same period.That is, the first air conditioner 10a because
During operating and stopping in turn, when the first human body detection sensor 51a detects that people also keeps stopping this period indoors
Only state.This such as by during this section untill moment t3 to moment t4 the second air conditioner 10b be in dormant state, Yi Ji
During this section untill moment t5 to moment t6 the 3rd air conditioner 10c be in dormant state situation find out as to
One~the 3rd air conditioner 10a~10c is common.That is, each air conditioner 10a~10c stops because operating in turn
During only, when each human body detection sensor 51a~51c detects that people also keeps dormant state this period indoors.
Accordingly, because superfluous operating will not be carried out, so power consumption can be suppressed, while the long lifetime of air-conditioning system 1 can also be sought.
As shown in fig. 6, when the first~the 3rd air conditioner 10a~10c stops when stopping because operating in turn in a part
Between can all operating is stopped in T1.Particularly, during this section untill moment t8 to moment t9 because perform not when act
And the 3rd air conditioner 10c for making operating stop also can be thereafter this section untill moment t5 to moment t6 during, one
All operating is set to stop in part stop time T1.So, the first~the 3rd air conditioner 10a~10c stops because operating in turn
The length of stop time (here, being a part of stop time T1) only not because whether due to not when action the edge that has stopped
Therefore change.Accordingly, because although not necessarily in whether carried out not when action come change in turn operating under when stopping
Between, so the control under operating in turn can be made relatively simple.
＜ ＞ when stopping human testing control
Then, reference picture 7, with regard to stopping being said with the difference during executor's physical examination observing and controlling when human testing controls
It is bright.
As due in t0, the operating portion 22 of remote control 20 is started to operate in turn, but do not enter pedestrian to it
Physical examination, which is surveyed, to be started to operate.Then, just start it is above-mentioned operate in turn, on the other hand, controlled without human testing.That is,
When human body detection sensor 51 detects people not indoors, also turn into do not perform not when the state that acts.
Then, for example, as due in t8 after have passed through the stipulated time, third party's body detecting sensor 51c is detected
People is not indoors.Now, in the case where operating in turn, the 3rd air conditioner 10c has been selected as conveyer.Also, the because even third party
Body detecting sensor 51c detect people not indoors also without not when act, so the 3rd air conditioner 10c is still selected as transporting
Favourable turn.Therefore, the 3rd air conditioner 10c will not also stop during this section from moment t8 to moment t9 and can carry out air-conditioning fortune
Turn.In moment t8, in the case where operating in turn, the first air conditioner 10a is selected as conveyer, and the second air conditioner 10b is selected as the machine that stops.
Therefore, it will utilize two air conditioners 10a, 10c in addition to the second air conditioner 10b that room air is adjusted.
It is identical when other action situations are with executor's physical examination observing and controlling.It should be noted that in the figure 7, in order to indicate
Relation between the operating condition of nobody and air conditioner 10 and show the detection state of human body detection sensor 51, Bu Guoye
The detection function of human body detection sensor 51 can be made to stop with human testing control is stopped.
As described above, when making one physical examination observing and controlling stop and stopping, the operating condition of air conditioner 10 will not be because interior be either with or without people
And change.Even if this is for being also required to make the progress operation of air conditioner of air conditioner 10 of specified quantity to come to sky during indoor nobody
It is extremely useful for the purposes (for example, data center) that gas is adjusted.
- effect of embodiment-

Moreover, because can perform and stop comprising not when act human testing control between switch over, institute
That can judge whether according to either with or without people air conditioner 10 should be allowed between operating condition and dormant state to enter according to purposes
Row switching, so as to provide the air-conditioning system 1 for being suitable for various uses the most.
And then because each air conditioner 10 in turn operate under stop time length not because whether due to not when move
The reason made and stopped changes, thus although not necessarily in whether carried out not when action change each air conditioner
