When mode was moved the compressor 11 that originally stopped according to the variation of the method for operation as described above, existence will reach the problem that could start compressor 11 after the pressure balance.Fig. 9 for air conditioner when halted state begins to carry out first section operation the first compressor 11a and the pressure of the second compressor 11b change schematic diagram.Begin first section operation, then the outlet of the first compressor 11a and suction inlet sharply become high pressure and low-pressure state, and the suction inlet of the second compressor 11b that stops graduates into low pressure, reaches uniform pressure with the suction inlet of the first compressor 11a afterwards through the Ts time (a-quadrant).If first section in service because the conversion of the method for operation be need start the second compressor 11b time, starting the second compressor 11b after about elapsed time Ts after beginning to carry out first section operation could normally move.
But reach the pressure balanced time, has difference according to the configuration of each air conditioner or the state of compressor 11, therefore in the time of will starting the compressor 11 that stops, compressor 11 in can be earlier out of service carries out the operation of next stage through control after reaching the required certain time interval T s of pressure balance then.In addition, owing to when when reaching pressure balance, also not starting the compressor 11 that stops, therefore utilizing pressure sensor monitoring pressures such as (not shown) balance whether to carry out the operation of next stage through certain time interval T s.
The following air conditioner control method that each method of operation conversion process that is shown in Table 1 according to first embodiment of the invention is described with reference to Figure 10 to Figure 12 b.
At first, Figure 10 be illustrated in the 3rd section in service, the control method the when method of operation is transformed to first section or second section method of operation.When being selected the 3rd section operation by order button 31 or being caused reason such as cooling load amount increase to select the 3rd section operation because of the rising of indoor temperature by the user, microcomputer 30 each drive unit of control begin to carry out the 3rd section operation (S100); Thereupon, the first compressor 11a and the second compressor 11b bring into operation, the first outlet drive division 27a and the second outlet drive division 27b all open the first outlet 26a and the second outlet 26b, discharge cooling air (S110) by the first outlet 26a and the second outlet 26b.
The 3rd section in service, by the variation of user's selection or indoor load and when importing method of operation figure signal, microcomputer 30 judges whether the method for operation is transformed to second section (S120) by the 3rd section; If be transformed to second section method of operation, then stop the first compressor 11a (S130); Control the first outlet drive division 27a to close the first outlet 26a, move and conversion outlet (S140) according to second section with this; And, continue to drive the second compressor 11b and carry out second section operation (S150).
Be not transformed to second section operation as if being judged as, then judge whether to be transformed to first section operation (S160) from the 3rd section operation at step S120; If the method for operation is transformed to first section operation, then stop the second compressor 11b (S170); Control the second outlet drive division 27b and close the second outlet 26b, move and conversion outlet (S180) according to first section with this; And, continue to drive the first compressor 11a and carry out first section operation (S190).If be judged as at step S160 and do not select first section operation, then thinking does not have the conversion of the method for operation and keeps the 3rd section operation (S200).So, when being transformed to first section or second section operation, there is not special time delay and according to the method for operation operation of conversion by the 3rd section operation.
Control method when secondly, Figure 11 a and Figure 11 b are illustrated in first section method of operation in service and are transformed to second section or the 3rd section method of operation.When being selected the method for operation or being selected to carry out first section operation because of the reason of indoor load by the user, microcomputer 30 each drive unit of control begin to carry out first section operation (S210); Thereupon, the first compressor 11a begins to start, and controls the first outlet drive division 27a and opens the first outlet 26a (S220); The air that operates in evaporator cools by the first compressor 11a is discharged to indoor by the first outlet 26a.
If at first section in service input method of operation figure signal, then microcomputer 30 judges whether this signal is the 3rd section and moves figure signal (S230); If judge to be chosen as the 3rd section operation, then judge first section operation beginning after Cumulative Elapsed Time whether passed through scheduled time Ts (S240); If Cumulative Elapsed Time is less than Ts, the first compressor 11a (S250) in then out of service; And keep the required certain hour of pressure balance (three minutes) (S260); Afterwards, start the first compressor 11a and the second compressor 11b (S270).If judge that at step S240 first period operation accumulated running time is more than the Ts, then do not stop the first compressor 11a and directly start the second compressor 11b (S300).
If the first compressor 11a and the second compressor 11b begin to start, then the first outlet drive division 27a and the second outlet drive division 27b begin the 3rd section operation (S280, S290) after all opening the first outlet 26a and the second outlet 26b.
Not the 3rd section operation as if being judged as, then judge whether to be transformed to second section operation (S310) at step S230; If judge not to be transformed to second section, then keep first section operation (S320).On the contrary, if the method for operation is transformed to second section operation, judge then whether first section operation Cumulative Elapsed Time has passed through scheduled time Ts (S330); If Cumulative Elapsed Time is less than Ts, the first compressor 11a in then out of service, and wait for certain hour (three minutes) (S340, S350); Through after the certain hour, start the second compressor 11b (S360).If moving accumulated running time for first section in step S330 judgement is more than the Ts, then stop to start the second compressor 11b (S390, S360) after the first compressor 11a.
The microcomputer 30 control first outlet drive division 27a and the second outlet drive division 27b close the first outlet 26a and open the second outlet 26b, with this, according to second section operation conversion outlet (S370); Then, carry out second section operation (S380).So, first section in service, when the method for operation is transformed to second section or the 3rd section operation, keeps the compressor 11 that stops and reaching after pressure balance required waiting time, according to the method for operation operation of conversion.
Control method when Figure 12 a and Figure 12 b are illustrated in second section method of operation in service and are transformed to first section or the 3rd section method of operation.Because the method is similar to the method shown in Figure 11 a and Figure 11 b, below omit explanation.
Figure 13 is the air conditioner control method schematic diagram according to second embodiment of the invention. it is the fiducial time of Ts that second embodiment will reach the required time set of pressure balance unlike first embodiment, but on the first compressor 11a and the second compressor 11b, pressure sensor (not shown) is set, according to pressure sensor judge whether to reach pressure balance and can start after start compressor 11.
Below, enumerate the example that is transformed to second section method of operation first section method of operation in service and describe.At first begin first section operation and start the first compressor 11a, control the first outlet drive division 27a, discharge cooling air (S600, S610) by the first outlet 26a to open the first outlet 26a.
At first section second section method of operation figure signal of input in service (S620); And utilize the value that pressure sensor detected that is arranged on the second compressor 11b to judge whether the second compressor 11b reaches pressure balance (S630); Do not reach pressure balance if be judged as, stop to wait for certain hour (three minutes) (S640, S650) after the first compressor 11a; Through starting the second compressor 11b (S660) after the certain hour.If judge that at step S630 the second compressor 11b has reached pressure balance, then stop directly to start the second compressor 11b (S690, S660) after the first compressor 11a.
The first outlet drive division 27a closes the first outlet 26a after beginning to start the second compressor 11b, and the second outlet drive division 27b opens the second outlet 26b, discharges cooling air (S670) by the second outlet 26b; With this, according to carrying out second section operation (S680) after second section each drive division of operation control.
