Now, detect the as above operation in tandem of the method for the misconnection of the compressor of the variable capacitance air conditioner of configuration with explaining.
Fig. 4 A and 4B show the flow chart according to the method for the misconnection of the compressor of detection variable capacitance air conditioner of the present invention.
As explaining the pre-conditioned of operation of the present invention, suppose that the first and second compressor 12a and 12b are TANDOM controllers 150, therefore, the first compressor 12a has higher relatively capacity 60%, the second compressor 12b and has relatively low capacity 40%.
After variable capacitance air conditioner had been installed, in order to confirm whether normally to have connected a plurality of compressor 12a and 12b, when the system of electric power starting and air-conditioner resetted, controller 150 determined whether the control of the misconnection of compressor 12a and 12b finishes (S100).
If do not finish the control of misconnection, determine that then the first compressor 12a is in ON state (S110).If the first compressor 12a is in the ON state, controller 150 has determined whether to collect fully the decision-making data (S120) of the first compressor 12a.
If the collection of the decision-making data of the first compressor 12a is not finished, the continuous operating time of the controller 150 countings first compressor 12a (is determined the required minimum time of misconnection exactly to determine whether to have passed through the scheduled time; Approximate 30 minutes) (S130 is to S140).
If passed through the scheduled time, indoor temperature detecting unit 110 perception indoor temperatures, and indoor pipe temperature detecting unit 120 perception are according to the temperature of the pipe of first heat exchanger 52 of the operation variation of the first compressor 12a.First imports the temperature of the ingress pipe of the temperature detecting unit 130 perception first compressor 12a, that is, and and the first outdoor importing temperature T ca.The temperature value of perception is outputed to controller 150.
Thus, controller 150 is according to the sense temperature value from each temperature detecting unit 110,120 and 130 inputs, store the difference DELTA Ta between the first outdoor importing temperature T ca and indoor temperature and the indoor pipe temperature, then, finish the collection (S150) of the decision-making data of the first compressor 12a.
Simultaneously, if locate to determine that in step (S110) the first compressor 12a is not in the ON state, determine that the second compressor 12b is in ON state (S160).If the second compressor 12b is not in the ON state equally, make the counting invalid (S170) of the continuous operating time of each first and second compressors 12a and 12b, controller 150 returns S100.
Yet if the second compressor 12b is in the ON state, controller 150 has determined whether to collect fully the decision-making data (S180) of the second compressor 12b.If do not collect the decision-making data of the second compressor 12b fully, the continuous operating time (S190) of the controller 150 countings second compressor 12b.
Then, controller 150 determines whether the continuous operating time of the second compressor 12b has passed through the scheduled time (approximate 30 minutes) (S200).If passed through the scheduled time, indoor temperature detecting unit 110 perception indoor temperatures, and indoor pipe temperature detecting unit 120 perception are according to the temperature of the pipe of first heat exchanger 52 of the operation variation of the second compressor 12b.Second imports the temperature of the ingress pipe of the temperature detecting unit 140 perception second compressor 12b, that is, and and the second outdoor importing temperature T cb.The temperature value of perception is outputed to controller 150.
Thus, controller 150 is according to the sense temperature value from each temperature detecting unit 110,120 and 130 inputs, store the difference DELTA Tb between the second outdoor importing temperature T cb and indoor temperature and the indoor pipe temperature, then, finish the collection (S210) of the decision-making data of the second compressor 12b.
Under normal situation about connecting, because the first compressor 12a has larger capacity 60%, and the second compressor 12b has than low capacity 40%, the indoor pipe variations in temperature that the indoor pipe variations in temperature that is caused by the operation of the first compressor 12a causes greater than the operation by the second compressor 12b.As a result, difference DELTA Ta is greater than difference DELTA Tb, and the first outdoor importing temperature T ca is less than the second outdoor importing temperature T cb.Result by obtaining has calculated compressor 12a and the normal of 12b and has been connected.
If difference DELTA Ta is less than difference DELTA Tb, controller 150 is tentatively determined the misconnections of compressors.In order to determine the appearance of misconnection exactly, controller determines that whether the first outdoor importing temperature T ca is greater than the second outdoor importing temperature T cb (S240).
If the first outdoor importing temperature T ca is greater than the second outdoor importing temperature T cb, controller 150 is determined compressor 12a and the obvious misconnection of 12b, therefore switch its compressor control port one 52a and 152b, changing being connected of the first and second compressor 12a and 12b, and finish the control (S250) of misconnection.
In this manner, controller 150 has been proofreaied and correct the misconnection of compressor 12a and 12b, and need not manually to change being connected of compressor 12a and 12b, can have no the local variety of issue that is caused by misconnection that solves thus.
If controller 150 determines that in step (S240) the first outdoor importing temperature T ca is not more than the second outdoor importing temperature T cb, owing to can not determine misconnection exactly, controller 150 is postponed the decision-making of (defer) misconnection, and change the collection of the decision-making data of the first and second compressor 12a and 12b into be used for data the unfinished state (S260) that detects again, make the counting of continuous operating time of each first and second compressors 12a and 12b invalid simultaneously.
Simultaneously, if difference DELTA Ta is not more than difference DELTA Tb, controller 150 determines whether difference DELTA Ta equals difference DELTA Tb.If difference DELTA Ta and difference DELTA Tb are equal to each other, controller 150 is postponed the decision-making of misconnection, and change the collection of the decision-making data of the first and second compressor 12a and 12b into be used for data the unfinished state (S260) that detects again, make the counting of continuous operating time of each first and second compressors 12a and 12b invalid simultaneously.
If determine that in step (S235) difference DELTA Ta is not equal to difference DELTA Tb, controller 150 preliminary definite compressor 12a and the normal of 12b are connected.In order to determine normal the connection exactly, controller 150 determines that whether the first outdoor importing temperature T ca is less than the second outdoor importing temperature T cb (S270).
If the first outdoor importing temperature T ca is less than the second outdoor importing temperature T cb, controller 150 determines that compressor 12a obviously normally is connected with 12b, and finishes the control (S280) of misconnection.
Yet, if the first outdoor importing temperature T ca is not less than the second outdoor importing temperature T cb, owing to can not determine misconnection exactly, controller 150 is postponed the decision-making of misconnection, and change the collection of the decision-making data of the first and second compressor 12a and 12b into unfinished state, make the counting invalid (S260) of the continuous operating time of each first and second compressors 12a and 12b simultaneously.
Can total capacity be changed into three grades TANDOM compressor according to the number of separate compressors and explained the present invention although utilized, promptly, with two compressor 12a and 12b as an example, the present invention is not limited thereto and it is selected big or than the low capacity and the TS/ES compressor that can change according to the direction of rotation of motor to be applied to have.Certainly, this TS/ES compressor can be realized aspect and the effect identical with above-mentioned TANDOM compressor.
Therefore, provided above-mentioned explanation simply, as being used to realize according to the equipment of the misconnection of the compressor of detection variable capacitance air conditioner of the present invention and the exemplary embodiments of method, those skilled in the art can be understood that, under the prerequisite that does not break away from by the appended disclosed scope and spirit of the present invention of claim, can carry out various modifications, interpolation and replacement.
