(the beginning condition of control)
At first, 25 pairs of room temperature monitoring controls that whether begin off-premises station 2 sides of outdoor control part are judged.
Begin room temperature monitoring control in the occasion that satisfies following 2 conditions.
(1) air conditioner 1 is in service in heating.
(2) air conditioner 1 is not in defrosting.
(startup of the room temperature supervision timer of each indoor set)
Below, as shown in Figure 4, for each indoor set 3a, 3b, 3c, 3d, various room temperature supervision timers are activated.Here, Tm2 (A) expression indoor set 3a room temperature monitoring permission timer that the time that is allowed to carry out the room temperature monitoring is carried out timing.In addition, for other indoor sets 3b, 3c, 3d, the mark of changing in the parantheses is represented.Such as, the monitoring permission timer of indoor set 3b is represented with Tm2 (B).Below, also use same mark for other timers.
Tm01 (B) expression indoor set 3b forbids timer for the first time.Forbid that for the first time timer is meant that outdoor control part 25 is from beginning to carry out the timer that room temperature monitoring control is carried out timing to the time of forbidding the room temperature monitoring for the first time.Timer Tm01 (A) aftermentioned of forbidding for the first time of indoor set 3a is set at zero like that, so not expression among Fig. 4.
The timer value of 25 pairs of each timers of outdoor control part carries out following setting.
At first, indoor set 3a, 3b, 3c, 3d will forbid room temperature monitoring respectively time as room temperature monitoring forbid that time T 1, indoor set 3a, 3b, 3c, 3d will allow the time of room temperature monitoring to monitor permitted hours T2 as room temperature respectively.For each indoor set 3a, 3b, 3c, 3d, the room temperature monitoring forbids that time T 1 equates with room temperature monitoring permitted hours T2.Therefore, the timer value of the monitoring of each indoor set 3a, 3b, 3c, 3d permission timer Tm2 (A), Tm2 (B), Tm2 (C), Tm2 (D) all is T2.In addition, the monitoring of each indoor set 3a, 3b, 3c, 3d forbids that timer Tm1 (A), Tm1 (B), Tm1 (C), Tm1 (D) all are T1.Here, monitoring forbids that timer is meant the timer that each indoor set 3a, 3b, 3c, 3d carry out timing to the time of forbidding the room temperature monitoring, the beginning room temperature has been controlled the 2nd later monitoring forbidden that the time carries out timing.
The timer value of forbidding timer for the first time to each indoor set 3a, 3b, 3c, 3d is set by following.
At first, the platform number of indoor set that will carry out room temperature monitoring is as N, and then the supervision interval Δ T of each indoor set 3a, 3b, 3c, 3d is tried to achieve by following formula.
ΔT＝(T1+T2)÷N-T2
The supervision interval of each indoor set is meant from the room temperature of a certain indoor set monitoring permission and finishes, the time till the room temperature monitoring permission beginning of next indoor set.
Carry out the room temperature monitoring by the order of indoor set 3a, indoor set 3b, indoor set 3c, indoor set 3d, then the timer value of forbidding timer for the first time of each indoor set is provided by following formula respectively.
Tm01(A)＝(ΔT+T2)×0
Tm01(B)＝(ΔT+T2)×1
Tm01(C)＝(ΔT+T2)×2
Tm01(D)＝(ΔT+T2)×3
When room temperature monitoring control beginning, the timer of forbidding for the first time of then outdoor control part 25 couples of each indoor set 3a, 3b, 3c, 3d starts.
Then, the timer timing of forbidding for the first time as each indoor set 3a, 3b, 3c, 3d finishes the monitoring permission timer of outdoor control part 25 startup each indoor set 3a, 3b, 3c, 3d.Then, during the beginning condition of room temperature monitoring is set up, each indoor set 3a, 3b, 3c, 3d are monitored circularly the startup of forbidding timer and monitoring permission timer.
Below, represent the concrete example of the timing of each timer.
Under this condition, supervision interval Δ T=0.This does not stay time interval ground not start the monitoring permission timer of other indoor sets immediately after being the monitoring permission timer timing end of a certain indoor set of expression.
Each indoor set 3a, 3b, 3c, 3d forbid that for the first time timer is as follows respectively.
Tm01(A)＝0s
Tm01(B)＝90s
Tm01(C)＝180s
Tm01(D)＝270s
Monitoring permission timer Tm2 (A), the Tm2 (B) of each indoor set 3a, 3b, 3c, 3d, Tm2 (C), Tm2 (D)=90s, timer Tm1 (A), Tm1 (B), Tm1 (C), Tm1 (D)=270s are forbidden in monitoring.
Relation between each timer as shown in Figure 5.
After beginning room temperature monitoring control, outdoor control part 25 starts timer Tm01 (A)=0s, Tm01 (B)=90s, Tm01 (C)=180s, Tm01 (the D)=270s that forbids for the first time of each indoor set 3a, 3b, 3c, 3d.
When the monitoring of indoor set 3b permission timer Tm2 (B) timing finishes, indoor set 3c forbid for the first time timer Tm01 (C) also timing finish.Then, start the monitoring permission timer Tm2 (C) of indoor set 3c.Below, also identical for indoor set 3d.
After the monitoring permission timer Tm2 (D) of indoor set 3d timing finished, the monitoring of indoor set 3a forbade that timer Tm1 (A) (not shown) timing finishes, and started the monitoring permission timer Tm2 (A) of indoor set 3a once more.Repeat this control later on.
No matter whether indoor set 3a, 3b, 3c, 3d be in the temperature controller off-state, for all indoor set 3a, 3b, 3c, 3d, outdoor control part sends the occasion of monitoring enabling signal, and during the timing of above-mentioned monitoring permission timer, outdoor control part 25 sends the monitoring enabling signal to the object indoor set.Thus, can stagger time ground to each indoor set 3a, 3b, 3c, 3d transmission monitoring enabling signal with easy control.
(only the indoor set that is in the temperature controller off-state being sent the control of the occasion of monitoring enabling signal)
Only the indoor set of the temperature controller off-state that is in heating operation is sent the occasion of monitoring enabling signal, except above-mentioned control, also carry out following control.
After a certain indoor set that is in the temperature controller on-state was originally disconnected by temperature controller, the temperature controller of this indoor set disconnects forbade that for the first time timer is activated.It is that time T 1 is forbidden in the room temperature monitoring that temperature controller disconnects the timer value of forbidding timer for the first time.Below, as shown in Figure 6, in the monitoring of indoor set 3a permission timer Tm2 (A) timing, indoor set 3d disconnects as temperature controller and describing.
In this control, monitoring permission flag symbol f (D) is made the following judgment.
(3) temperature controller disconnects and forbids that for the first time timer Tm3 (D) timing finishes.
(4) monitoring permission timer Tm2 (D) is not in timing.
All satisfy the occasion of the condition of above (3) and (4), make monitoring permission flag symbol f (D)=1.In addition,
(5) temperature controller disconnects and forbids that for the first time timer Tm3 (D) is in timing.
(6) monitoring permission timer Tm2 (D) is not in timing.
All satisfy the occasion of the condition of above (5) and (6), make monitoring permission flag symbol f (D)=0.
The monitoring permission flag symbol of each indoor set is zero when monitoring control beginning.
Below, all satisfied following (7) occasion to the condition of (10), send the monitoring enabling signal to indoor set 3d.
(7) temperature controller of indoor set 3d disconnects and forbids that for the first time timer Tm3 (D) is not in timing.
(8) indoor set 3d is in heating as dissengaged positions.
(9) monitoring of indoor set 3d permission timer Tm2 (D) is in timing.
(10) the monitoring permission flag of indoor set 3d symbol f (D)=1.
But, the temperature controller of each indoor set 3a, 3b, 3c, 3d disconnects and forbid that for the first time timer Tm3 (A), Tm3 (B), Tm3 (C), Tm3 (D) are eliminated when beginning room temperature monitoring control.
By above control, can be only at the indoor set of temperature controller off-state, the platform number of the indoor set that carries out the room temperature monitoring is simultaneously limited.Therefore, compare with the occasion that sends room temperature monitoring enabling signal to all indoor set 3a, 3b, 3c, 3d, the quantity of the indoor set that is restricted is few.That is,, can prolong the time that sends the monitoring enabling signal for per 1 indoor set.Therefore, in this air conditioner 1, the probability of chance that indoor set loses monitoring is little.
(feature of this air conditioner)
In this air conditioner 1, indoor control part 34a, 34b, 34c, 34d receive room temperature monitoring enabling signal, and when satisfying the beginning condition of room temperature monitoring, carry out the room temperature monitoring.Therefore, a certain indoor control part even be to satisfy the occasion of the beginning condition of room temperature monitoring from the condition judgment of its indoor set inside, did not carry out the room temperature monitoring yet before outdoor control part 25 allows the room temperatures monitoring.Therefore, outdoor control part 25 can not send the monitoring enabling signal to the indoor set more than 2 simultaneously, and the time ground that staggers sends the monitoring enabling signal to each indoor control part 3a, 3b, 3c, 3d.Therefore, the indoor set that does not have more than 2 carries out the room temperature monitoring simultaneously.Therefore, the indoor fan of the indoor set more than 2 is driven, can not apply rapid influence cold-producing medium.Thus, this air conditioner 1 can suppress the rapid decline that blows out temperature in the operation room.In room temperature when monitoring,, the internal fan 32a of drive chamber, 32b, 32c, 32d suck the inside of indoor set 3a, 3b, 3c, 3d with room air, so in this air conditioner, even also can correctly carry out the detection of indoor temperature in the indoor set of temperature controller off-state.
And the monitoring permission timer of each indoor set 3a, 3b, 3c, 3d forbids that with monitoring the timer value of timer is identical.That is, outdoor control part 25 will be monitored enabling signal to each indoor control part 34a, 34b, 34c, 34d transmission with the time interval of equalization.Therefore, with identical circulation room temperature is monitored enabling signal sends to each indoor set 3a, 3b, 3c, 3d with staggering the time.Therefore, can will carry out the room temperature monitoring give each indoor set 3a, 3b, 3c, 3d with having equal opportunities.The room temperature monitoring number of times generation deviation that can suppress thus, each indoor set 3a, 3b, 3c, 3d.
(other examples)
The platform number of the indoor set that is connected with off-premises station 2 is not limited to described number of above-mentioned example, also more than 2 or 3 or 5.
In addition, in the above-mentioned example, not can with the time at the indoor set more than 2, monitoring permission timer carries out timing, but the occasion little to the influence of cold-producing medium also can make the timing of monitoring permission timer simultaneously to each 2 or more indoor set.
In the above-mentioned example, send the monitoring enabling signals, when the monitoring beginning condition of indoor set 3a, 3b, 3c, 3d is met, and receive the occasion of monitoring enabling signal, carry out the room temperature monitoring from outdoor control part 25.But the signal that outdoor control part 25 sends is not limited to monitor enabling signal, also can send the monitoring inhibit signal.This occasion when the monitoring beginning condition of indoor set 3a, 3b, 3c, 3d is met and does not receive the occasion of monitoring inhibit signal, is carried out the room temperature monitoring.
The possibility of utilizing on the industry
As utilize air conditioner of the present invention, just can suppress the rapid decline that blows out temperature in the operation room, Simultaneously, also can correctly carry out indoor temperature in the indoor set of temperature controller off-state detects.
