Fig. 2 is the flow chart that the main program of the processing after the service restoration of above-mentioned control device 6 is shown, and Fig. 3 is the flow chart of subprogram of computing of compressor start T time delay of the step S3 of Fig. 2.
Below, the work of above-mentioned control device 6 is described according to Fig. 2 and Fig. 3.
At first, in Fig. 2, behind the service restoration, handle at the beginning, just judge in step S1 whether the microcomputer of control device 6 is reset, be reset if be judged to be microcomputer, then proceed to step S2, on the other hand, be not reset, then finish this processing if be judged to be microcomputer.That is, the state before power failure is under the situation of operating condition, because microcomputer is reset, so proceed to the processing that later running is reset to step S2, on the other hand, the state before power failure is under the situation of halted state, microcomputer is not reset, and finishes this processing.
Then, under the situation that proceeds to step S2, from EEPROM 6 sense datas.That is, read the setting value (air quantity setting value) that is illustrated in owing to the operation information under the state before shutting down.
Secondly, proceed to step S3, carry out the computing of compressor 2 start delay time T.

Moreover, for the purpose of being easy to explanation, in the computing of time delay of Fig. 3, omitted the relevant specifically explanation of numerical operation, still, below specifically describe the one example.
For example, suppose that respectively the desirable value of each parameter is as follows:
The air quantity setting value: automatically=0, L switch=3, ML switch=4
M switch=5, HM switch=6, H switch=7
The count value of 1 second timer: 0~59
The count value of power supply synchrotimer: 0~99 (when supply frequency is 50Hz)
0~119 (when supply frequency is 60Hz).And, suppose that room temperature and indoor heat converter temperature are 18 ℃, if utilize microcomputer to carry out 8 computing, then at first obtain room temperature 12h (16 system number) and indoor heat converter temperature 12h (16 system number) sum, add 40h (16 system number), obtain timer setting value TN
TN=12h+12h+40h=64h
Moreover, when obtaining above-mentioned timer setting value, having added 40h, this is to make needed processing aspect the delay timer 6d work.And, after the count value of count value that has added 1 second timer and power supply synchrotimer, make high-order 2 bits become 0.Secondly, be under zero the situation at timer setting value TN, deciding timer setting value TN is 3h, at timer setting value TN be to remove with 3 to surplus under 1 the situation, sets value on the TN at timer to add 2, in addition, at timer setting value TN be except that surplusing under 2 the situation with 3, on timer setting value TN, add 1, thus, make timer setting value TN become 3 multiple.Then, on above-mentioned timer setting value TN, added 40h after, it is set delay timer 6d.Like this, the multiple that timer setting value TN that above-mentioned delay timer 6d is set has become, the least count value of delay timer 6d becomes 100ms, and thus, TN is set at every through the T time delay of 300ms the timer setting value.This 300ms is that the nonoverlapping minimum time of peak point current during compressor start is poor in this case the running of air regulator being reset.Thereby, to every under the delay timer through discrete T time delay that comes of 300ms.

External air temperature: 33 ℃
Indoor heat converter temperature: 26 ℃
Outdoor heat converter temperature: 36 ℃
Design temperature: 26 ℃
Then time delay, T was
T=3+5+29+33+26+36+26=158[second]
(at this moment, time delay T initial value be zero)
In above-mentioned example, according to the setting value of expression operation information and the temperature of expression operating condition, utilize time delay calculating part 6c to calculate T time delay, but, can be according to the either party of temperature of the setting value or the expression operating condition of expression operation information, utilize the time delay calculating part to calculate time delay.In addition, can be in advance each air regulator be set different time delay of T or set after being provided with, perhaps also can utilize random number to come the computing relay time.
In addition, in above-mentioned example, in advance T setting time delay refrigerant lines is all pressed 3 minutes stand-by times of usefulness, and various parameter additions, but, also 3 minutes standby timers can be set in addition, after power up and standby timer end in 3 minutes, make delay timer carry out timing.
In addition, in above-mentioned example, the air regulator that only cools off running has been described, still, the present invention also can be applied to cool off the air regulator that turns round and add heat run certainly.In addition, the air regulator when indoor set 10 and off-premises station 20 are the branch open form has been described, still, the air regulator that the present invention also can be applied to indoor unit and outdoor unit when being one-piece type.
