Then, be specifically described operating in turn with reference to Fig. 4.In this example, under a part stops running, from the first ~ three air conditioner 10a ~ 10c, select an air conditioner 10 as the machine that stops, thus make a tableland from the first air conditioner 10a become the machine that stops successively.Under initial operation, the first ~ three air conditioner 10a ~ 10c is all selected as conveyer.
As due in t0, operation is started in turn to the operating portion 22 of remote controller 20, thus the first ~ three air conditioner 10a ~ 10c all becomes conveyer.Such as, the control part 23 of remote controller 20 all sends to the first ~ three air conditioner 10a ~ 10c releasing instruction of stopping.Thus, under initial operation, just by three air conditioner 10a ~ 10c, room air is regulated.
Then, when have passed through due in t1 after initial operation time T0, from the first ~ three air conditioner 10a ~ 10c becoming conveyer, the first air conditioner 10a is selected as the machine that stops.Such as, control part 23 sends to the first air conditioner 10a instruction of stopping.Thus, under in first time, a part stops running, just by two air conditioners 10b, 10c except the first air conditioner 10a, room air is regulated.
Then, when have passed through due in t2 after part stop time T1, the first air conditioner 10a having become the machine that stops just is selected as conveyer.Such as, control part 23 sends to the first air conditioner 10a releasing instruction of stopping.Thus, under first time transition operation, next the predetermined second air conditioner 10b that will become the machine that stops proceeds operation of air conditioner, and the first air conditioner 10a having become the machine that stops then starts to carry out operation of air conditioner again.3rd air conditioner 10c also proceeds operation of air conditioner.Therefore, by three air conditioner 10a ~ 10c, room air is regulated.
Then, when have passed through due in t3 after transition operation time T2, from the first ~ three air conditioner 10a ~ 10c becoming conveyer, the second air conditioner 10b is selected as the machine that stops.Thus, under a second time part stops running, just by two air conditioners 10a, 10c except the second air conditioner 10b, room air is regulated.
Then, when have passed through due in t4 after part stop time T1, the second air conditioner 10b having become the machine that stops just is selected as conveyer.Thus, under second time transition operation, next the predetermined 3rd air conditioner 10c that will become the machine that stops proceeds operation of air conditioner, and the second air conditioner 10b having become the machine that stops then starts to carry out operation of air conditioner again.First air conditioner 10a also proceeds operation of air conditioner.Therefore, by three air conditioner 10a ~ 10c, room air is regulated.
Then, when have passed through due in t5 after transition operation time T2, from the first ~ three air conditioner 10a ~ 10c becoming conveyer, the 3rd air conditioner 10c is selected as the machine that stops.Thus, under in third time, a part stops running, just by two air conditioners 10a, 10b except the 3rd air conditioner 10c, room air is regulated.
Then, when have passed through due in t6 after part stop time T1, the 3rd air conditioner 10c having become the machine that stops just is selected as conveyer.Thus, under third time transition operation, next the predetermined first air conditioner 10a that will become the machine that stops proceeds operation of air conditioner, and the 3rd air conditioner 10c having become the machine that stops then starts to carry out operation of air conditioner again.Second air conditioner 10b also proceeds operation of air conditioner.Therefore, by three air conditioner 10a ~ 10c, room air is regulated.
Then, when have passed through due in t7 after transition operation time T2, from the first ~ three air conditioner 10a ~ 10c becoming conveyer, the first air conditioner 10a is again selected as the machine that stops.Thus, under the 4th part stops running, just by two air conditioners 10b, 10c except the first air conditioner 10a, room air is regulated.
As mentioned above, by allowing a part of air conditioner in multiple stage air conditioner 10 stop successively, and can make realize equalization the duration of runs of multiple stage air conditioner 10.Also by carrying out initial operation between the elementary period operated in turn, and the air conditioning capacity of air-conditioning system 1 can be suppressed to decline between the elementary period operated in turn.And then, transition operation is carried out by stopping between running in a part under operating in turn, thus can at the air conditioner 10 becoming the machine that stops from after the machine that stops switches to conveyer, the more following predetermined air conditioner 10 that will become the machine that stops be switched to from conveyer the machine that stops.The air conditioning capacity of air-conditioning system 1 is suppressed to decline thereby, it is possible to brought by everything that air conditioner 10 is switched to conveyer from the machine that stops.
< human detection control >
Then, control to be described to human detection with reference to Fig. 5.When having carried out human detection to the operating portion 22 of remote controller 20 and having started to operate (operation starting human detection control in order to instruction), air-conditioning system 1 has just carried out following process.It should be noted that, following process is the process that each indoor set 12 carries out separately.That is, the room control unit 42 be arranged in the indoor set 12 of the first air conditioner 10a carries out the action of step ST21 ~ step ST23 according to the output of the first body detecting sensor 51a.Second air conditioner 10b and the 3rd air conditioner 10c is also same.
(step ST21)
First, the human body detection sensor 51 of room control unit 42 pairs of indoor sets 12 detects that people is indoor or detect that people does not judge in indoor.When human body detection sensor 51 detects people in indoor, just enter step ST22.On the other hand, when human body detection sensor 51 detects people not in indoor, then step ST23 is entered.
(step ST22)
When human body detection sensor 51 detects people in indoor, room control unit 42 just allows the air conditioner 10 being provided with this human body detection sensor 51 carry out operation of air conditioner.Thus, the air conditioner 10 having people around just carries out operation of air conditioner.It should be noted that, with regard to be selected as the air conditioner 10 of the machine that stops because operating in turn for, even if the human body detection sensor 51 of this air conditioner 10 detects that people is in indoor, this air conditioner 10 also can not be selected as conveyer.After this, again step ST21 is entered.
(step ST23)
On the other hand, when human body detection sensor 51 detects people not in indoor, room control unit 42 just perform not time action.That is, by being provided with, room control unit 42 detects that people is not elected to be at the air conditioner 10 of the human body detection sensor 51 of indoor the machine that stops.Thus, around the air conditioner 10 of nobody just keeps dormant state.After this, again step ST21 is entered.
By repeatedly carrying out process as described above, thus according to people whether in indoor, the operating condition of air conditioner 10 can be switched.Further, when having carried out human detection end operation (terminating the operation of human detection control in order to instruction) to the operating portion 22 of remote controller 20, human detection has controlled just can terminate.
The concrete example > that < human detection controls
Then, control to be specifically described to human detection with reference to Fig. 6 and Fig. 7.In this example, carrying out carrying out human detection control in the above-mentioned air-conditioning system 1 operated in turn.And, can perform and stop comprise not time action human detection control between switch.At this, after first the situation (with reference to Fig. 6) of executor's body detection control being described, then the situation stopping human detection controlling (with reference to Fig. 7) is described.
(when executor's body detection control)
As shown in Figure 6, as due in t0, just to the operating portion 22 of remote controller 20 start in turn operation and human detection start operation.So, just start above-mentionedly to operate in turn, pedestrian's body detection control of going forward side by side.That is, when human body detection sensor 51 detects people not in indoor, just become can perform not time action state.
During this section from moment t0 to moment t8, the first ~ three human body detection sensor 51a ~ 51c detects that people is in indoor, thus the first ~ three air conditioner 10a ~ 10c all can not because of perform not time action and be in dormant state.Therefore, during this section from moment t0 to moment t8, the operating condition of the first ~ three air conditioner 10a ~ 10c can be switched because operating in turn.
Then, such as, when have passed through due in t8 after the stipulated time, the 3rd human body detection sensor 51c detects people not in indoor.Now, under operating in turn, the 3rd air conditioner 10c is selected as conveyer.In contrast, at moment t8, the 3rd air conditioner 10c can because of perform not time action and operation of air conditioner is stopped.And at moment t8, under 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, the first air conditioner 10a in three air conditioner 10a ~ 10c is only utilized to regulate room air.
Then, when have passed through due in t9 after the stipulated time, the 3rd human body detection sensor 51c detects that people is in indoor again.So, with regard to do not carry out not time action, the 3rd air conditioner 10c is just selected as conveyer again.Thus, the 3rd air conditioner 10c carries out operation of air conditioner.And at moment t9, under 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, two air conditioners 10a, 10c except the second air conditioner 10b are utilized to regulate room air.
At this, during this section from moment t1 to moment t2, the first air conditioner 10a is selected as the machine that stops under operating in turn.On the other hand, in same period, the first body detecting sensor 51a of the first air conditioner 10a detects that people is in indoor.Under these conditions, the first air conditioner 10a makes operation of air conditioner stop in same period.That is, the first air conditioner 10a during stopping because operating in turn, when the first body detecting sensor 51a detects that people also keeps dormant state during this period of time in indoor.This as by be in from this period of period second air conditioner 10b moment t3 to moment t4 dormant state and this period of period the 3rd air conditioner 10c from moment t5 to moment t6 be in the situation of dormant state found out be all common to the first ~ three air conditioner 10a ~ 10c.That is, each air conditioner 10a ~ 10c during stopping because operating in turn, when each human body detection sensor 51a ~ 51c detects that people also keeps dormant state during this period of time in indoor.Thus, because surplus running can not be carried out, so power consumption can be suppressed, the long lifetime of air-conditioning system 1 can also be sought simultaneously.
As shown in Figure 6, the first ~ three air conditioner 10a ~ 10c can make running stop when stopping because operating in turn in part stop time T1.Particularly, during this section from moment t8 to moment t9 because of perform not time action and running has been stopped the 3rd air conditioner 10c also can after this from during this section moment t5 to moment t6, in part stop time T1, all make running stop.So, the length of stop time that the first ~ three air conditioner 10a ~ 10c stops because operating in turn (at this, being part stop time T1) not because of whether due to not time action and the cause of having stopped changes.Thus, because there is no need according to whether carry out not time action change stop time under running in turn, so the control under can making to operate in turn is comparatively simple.
< is > when stopping human detection controlling
Then, with reference to Fig. 7, when just stopping human detection control and executor's body detection control time difference be described.
As due in t0, to the operating portion 22 of remote controller 20 start in turn operation, but not to its carry out human detection start operation.So, just start above-mentionedly to operate in turn, on the other hand, do not carry out human detection control.That is, even if when human body detection sensor 51 detects people not in indoor, also become do not perform not time action state.
Then, such as, when have passed through due in t8 after the stipulated time, the 3rd human body detection sensor 51c detects people not in indoor.Now, under operating in turn, the 3rd air conditioner 10c is selected as conveyer.Further, even if because the 3rd human body detection sensor 51c detect people do not carry out in indoor yet not time action, so the 3rd air conditioner 10c is still selected as conveyer.Therefore, the 3rd air conditioner 10c also can not stop and can carry out operation of air conditioner during this section from moment t8 to moment t9.At moment t8, under 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, two air conditioners 10a, 10c except the second air conditioner 10b just can be utilized to regulate room air.
Identical when other action situation and executor's body detection control.It should be noted that, in the figure 7, in order to indicate nobody and air conditioner 10 operating condition between relation and show the detected state of human body detection sensor 51, but the measuring ability of human body detection sensor 51 also can be made to control along with stopping human detection and stop.
As mentioned above, when controlling when making human detection to stop, the operating condition of air conditioner 10 can not change because indoor have nobody.Even if this is for also needing the air conditioner 10 making specified quantity to carry out during indoor nobody, purposes (such as, data center) that operation of air conditioner regulated air is extremely useful.
