Describe the control device of compressor electric motor in the control method of compressor electric motor in the air-conditioner proposed according to the embodiment of the present invention, air-conditioner with reference to the accompanying drawings and there is the air-conditioner of this control device.
Fig. 1 is the flow chart of the control method of compressor electric motor in the air-conditioner according to the embodiment of the present invention.As shown in Figure 1, in this air-conditioner, the control method of compressor electric motor comprises the following steps:
S1, after compressor electric motor starts, starts timing, and detects outdoor environment temperature T4 in real time.
In an embodiment of the present invention, outdoor environment temperature T4 can be detected at the outdoor heat exchanger return air position set temperature detection module of air-conditioner.
Further, the air-conditioner in the embodiment of the present invention can be heat pump type air conditioner.
S2, when air-conditioner is in heating mode, judges whether air-conditioner performs defrost action.
S3, if so, then calculates the maximum reactive current of compressor electric motor, and controls to compressor electric motor the caloric value improving compressor electric motor according to the maximum reactive current of compressor electric motor according to the peak point current of compressor electric motor.
Further, according to one embodiment of present invention, when judging that air-conditioner performs defrost action, also timing time is reset.
Particularly, when calculating the maximum reactive current of compressor electric motor, first the load torque of compressor electric motor is obtained according to the outdoor environment temperature T4 detected in real time, because electromagnetic torque during air-conditioner stable operation is identical with load torque, therefore the watt current of compressor electric motor is calculated according to electromagnetic torque, then the peak point current of compressor electric motor is calculated according to the active power of compressor electric motor, the maximum reactive current of compressor electric motor is calculated again according to the peak point current of compressor electric motor, maximum reactive current finally by compressor electric motor controls compressor electric motor, when the reactive current of compressor electric motor strengthens, the coil heating amount of compressor electric motor strengthens, thus increase the output of heating capacity, the defrost time of air-conditioner can be shortened, improve the comfortableness of indoor environment.
S4, if not, then calculate the mean temperature T40 that compressor electric motor starts outdoor environment temperature in rear first Preset Time, and when judging that the running time of mean temperature T40 and compressor electric motor meets pre-conditioned, calculate the maximum reactive current of compressor electric motor according to the peak point current of compressor electric motor, and according to the maximum reactive current of compressor electric motor, the caloric value improving compressor electric motor is controlled to compressor electric motor.
Wherein, according to one embodiment of present invention, pre-conditionedly to comprise: (1) mean temperature T40 is more than or equal to the first preset temperature and is less than or equal to the second preset temperature and is more than or equal to the second Preset Time the running time of air-conditioner; Or (2) mean temperature T40 is less than the first preset temperature and is more than or equal to the 3rd Preset Time the running time of air-conditioner.
In addition, according to one embodiment of present invention, when meeting following arbitrary condition the running time of mean temperature T40 and compressor electric motor, controlling compressor electric motor and keeping current state operation the 4th Preset Time: (1) mean temperature T40 is more than or equal to the first preset temperature and is less than or equal to the second preset temperature and is less than the second Preset Time the running time of air-conditioner; Or (2) mean temperature T40 is less than the first preset temperature and is less than the 3rd Preset Time the running time of air-conditioner.
Further, when not meeting four kinds of above-mentioned conditions the running time of mean temperature T40 and air-conditioner, then control compressor electric motor and keep current state to run the 5th Preset Time.Such as, when mean temperature T40 is greater than the second preset temperature, because outdoor environment temperature is relatively high, now the heating capacity of air-conditioner generally can not be decayed, therefore the reactive current strengthening compressor electric motor is not needed, but control compressor electric motor maintenance current state operation the 5th Preset Time, after reaching the 5th Preset Time, again to judging the running time of mean temperature T40 and air-conditioner.
Preferably, the first Preset Time A can be 1-10 second, the second preset time t
s2can be 2-4 hour, the 3rd preset time t
s3can be 0.5-1 hour, the 4th Preset Time B can be 1-5 second, and the 5th Preset Time C can be 5-15 minute, the first preset temperature T4
s1can be 3-5 DEG C, the second preset temperature T4
s2can be 7-10 DEG C.
Particularly, after compressor electric motor starts, start timing, and detect outdoor environment temperature T4 in real time by the temperature detecting module of outdoor heat exchanger return air position, then judge whether air-conditioner is in heating mode, if air-conditioner is in heating mode, judge whether air-conditioner performs defrost action.If air-conditioner performs defrost action, then directly strengthen the reactive current of compressor electric motor, and timing time resets; If air-conditioner does not perform defrost action, then calculate compressor electric motor start after the first Preset Time A as the mean temperature T40 of outdoor environment temperature in 5 seconds, then mean temperature T40 and the first preset temperature T4s1, the second preset temperature T4s2 are compared, and t and the second preset time t s2 running time, the 3rd preset time t s3 of air-conditioner are compared.When the running time of air-conditioner does not meet the demands when outdoor environment temperature meets the demands, control compressor electric motor and keep current operating conditions to run the 4th Preset Time B as 2 seconds, rejudge; After all meeting the demands the running time of outdoor environment temperature, air-conditioner, strengthen the reactive current of compressor electric motor, and keep operation the 4th Preset Time B as 2 seconds, rejudge; All do not meet the demands when the running time of outdoor environment temperature, air-conditioner, keep operation the 5th Preset Time C as 10 minutes, rejudge, timing time resets.It should be noted that, when shutdown or the situation such as hang-up, defrost shutdown appear in air-conditioner in running, before all, record zeros data, and again count after air-conditioner resets.
Further, after compressor electric motor starts, start timing, and detect outdoor environment temperature T4 in real time.Then judge whether air-conditioner is in heating mode, if air-conditioner is in heating mode, judge whether air-conditioner performs defrost action.
If air-conditioner performs defrost action, then enter defrost pattern, strengthen the reactive current of compressor electric motor, and according to the maximum reactive current of compressor electric motor, the caloric value improving compressor electric motor is controlled to compressor electric motor, shorten the defrost time of air-conditioner, the temperature that can reduce indoor heat exchanger in defrost process causes indoor environment temperature to fluctuate impact because of reduction, improves the comfortableness of indoor environment.Meanwhile, also timing time is reset.
If air-conditioner does not perform defrost action, calculate the mean temperature T40 that compressor electric motor starts outdoor environment temperature in rear first Preset Time A, then judge whether t running time of mean temperature T40 and compressor electric motor meets pre-conditioned.When mean temperature T40 is more than or equal to the first preset temperature T4
s1and be less than or equal to the second preset temperature T4
s2, and t running time of air-conditioner is more than or equal to the second preset time t
s2, or mean temperature T40 is less than the first preset temperature T4

s3time, namely work as T4
s1≤ T40≤T4
s2and t>=t
s2or T40<T4
s1and t>=t
s3time, similarly, strengthen the reactive current of compressor electric motor, and according to the maximum reactive current of compressor electric motor, the caloric value improving compressor electric motor is controlled to compressor electric motor, the heating effect of air-conditioner can be improved, improve the comfortableness of indoor environment.
In the process, when mean temperature T40 is more than or equal to the first preset temperature T4
s1and be less than or equal to the second preset temperature T4
s2, and t running time of air-conditioner is less than the second preset time t
s2, or mean temperature T40 is less than the first preset temperature T4
s1and t running time of air-conditioner is less than the 3rd preset time t
s3time, namely work as T4
s1≤ T40≤T4
s2and t < t
s2or T40<T4
s1and t < t
s3time, compressor electric motor keeps current state to run the 4th Preset Time B, when reaching the 4th Preset Time B, and reclocking, and the judgement starting a new round.
As the mean temperature T40 of compressor electric motor with when not meeting four kinds of above-mentioned conditions the running time of compressor electric motor, then controlling compressor electric motor keeps current state to run the 5th Preset Time C, when reaching the 5th Preset Time C, reclocking, and the judgement starting a new round.
In addition, when compressor electric motor is shut down, before all, the zeros data of record, comprises timing time t, outdoor environment temperature T4 etc.After compressor electric motor starts, start heavy new recorded data.

According to one embodiment of present invention, pre-conditionedly to comprise: (1) mean temperature T40 is more than or equal to the first preset temperature and is less than or equal to the second preset temperature and is more than or equal to the second Preset Time the running time of air-conditioner; Or (2) mean temperature T40 is less than the first preset temperature and is more than or equal to the 3rd Preset Time the running time of air-conditioner.
In addition, according to one embodiment of present invention, when meeting following arbitrary condition the running time of mean temperature T40 and compressor electric motor 40, control module 30 controls compressor electric motor 40 and keeps current state operation the 4th Preset Time: (1) mean temperature T40 is more than or equal to the first preset temperature and is less than or equal to the second preset temperature and is less than the second Preset Time the running time of air-conditioner; Or (2) mean temperature T40 is less than the first preset temperature and is less than the 3rd Preset Time the running time of air-conditioner.
Further, when not meeting four kinds of above-mentioned conditions the running time of mean temperature T40 and air-conditioner, then control compressor electric motor 40 and keep current state to run the 5th Preset Time.Such as, when mean temperature T40 is greater than the second preset temperature, because outdoor environment temperature is relatively high, now the heating capacity of air-conditioner generally can not be decayed, therefore the reactive current strengthening compressor electric motor 40 is not needed, but control compressor electric motor 40 keeps current state to run the 5th Preset Time, after reaching the 5th Preset Time, again to judging the running time of mean temperature T40 and air-conditioner.
Preferably, the first Preset Time is 1-10 second, and the second Preset Time is 2-4 hour, 3rd Preset Time is 0.5-1 hour, and the 4th Preset Time is 1-5 second, and the 5th Preset Time C can be 5-15 minute, first preset temperature is 3-5 DEG C, and the second preset temperature is 7-10 DEG C.
According to one embodiment of present invention, the timing time of timer 10, when judging that air-conditioner performs defrost action, also resets by control module 30.
Particularly, after compressor electric motor 40 starts, start timing, and detect outdoor environment temperature T4 in real time by the temperature detecting module 20 of outdoor heat exchanger return air position, then judge whether air-conditioner is in heating mode, if air-conditioner is in heating mode, judge whether air-conditioner performs defrost action.
If air-conditioner performs defrost action, then directly strengthen the reactive current of compressor electric motor 40.Specifically, it is exactly the load torque first obtaining compressor electric motor according to the outdoor environment temperature T4 of temperature detecting module 20 detection in real time, because electromagnetic torque during air-conditioner stable operation is identical with load torque, therefore the watt current of compressor electric motor 40 is calculated according to electromagnetic torque, then the peak point current of compressor electric motor 40 is calculated according to the active power of compressor electric motor 40, the maximum reactive current of compressor electric motor 40 is calculated again according to the peak point current of compressor electric motor 40, maximum reactive current finally by compressor electric motor 40 controls compressor electric motor, when the reactive current of compressor electric motor 40 strengthens, the coil heating amount of compressor electric motor 40 strengthens, thus increase the output of heating capacity, the defrost time of air-conditioner can be shortened, improve the comfortableness of indoor environment.In addition, if air-conditioner performs defrost action, also the timing time of timer 10 is reset.
If air-conditioner does not perform defrost action, then calculate compressor electric motor 40 start after the first Preset Time A as the mean temperature T40 of outdoor environment temperature in 5 seconds, then mean temperature T40 and the first preset temperature T4s1, the second preset temperature T4s2 are compared, and t and the second preset time t s2 running time, the 3rd preset time t s3 of air-conditioner are compared.When the running time of air-conditioner does not meet the demands when outdoor environment temperature meets the demands, control compressor electric motor 40 and keep current operating conditions to run the 4th Preset Time B as 2 seconds, rejudge; After all meeting the demands the running time of outdoor environment temperature, air-conditioner, strengthen the reactive current of compressor electric motor 40, and keep operation the 4th Preset Time B as 2 seconds, rejudge; All do not meet the demands when the running time of outdoor environment temperature, air-conditioner, keep operation the 5th Preset Time C as 10 minutes, rejudge, timing time resets.It should be noted that, when shutdown or the situation such as hang-up, defrost shutdown appear in air-conditioner in running, before all, record zeros data, and again count after air-conditioner resets.
Further, as shown in Figure 2, after compressor electric motor 40 starts, start timing, and detect outdoor environment temperature T4 in real time by temperature detecting module 20.Then control module 30 judges whether air-conditioner is in heating mode, if air-conditioner is in heating mode, control module 30 judges whether air-conditioner performs defrost action.
If air-conditioner performs defrost action, then enter defrost pattern, strengthen the reactive current of compressor electric motor 40, and according to the maximum reactive current of compressor electric motor 40, the caloric value improving compressor electric motor 40 is controlled to compressor electric motor 40, shorten the defrost time of air-conditioner, the temperature that can reduce indoor heat exchanger in defrost process causes indoor environment temperature to fluctuate impact because of reduction, improves the comfortableness of indoor environment.Meanwhile, also the timing time of timer 10 is reset.
If air-conditioner does not perform defrost action, calculate the mean temperature T40 that compressor electric motor 40 starts outdoor environment temperature in rear first Preset Time A, then judge whether t running time of mean temperature T40 and compressor electric motor 40 meets pre-conditioned.When mean temperature T40 is more than or equal to the first preset temperature T4
s1and be less than or equal to the second preset temperature T4
s2, and t running time of air-conditioner is more than or equal to the second preset time t
s2, or mean temperature T40 is less than the first preset temperature T4
s1and t running time of air-conditioner is more than or equal to the 3rd preset time t
s3time, namely work as T4
s1≤ T40≤T4
s2and t>=t
s2or T40<T4
s1and t>=t
s3time, similarly, strengthen the reactive current of compressor electric motor 40, and according to the maximum reactive current of compressor electric motor 40, the caloric value improving compressor electric motor 40 is controlled to compressor electric motor 40, the heating effect of air-conditioner can be improved, improve the comfortableness of indoor environment.
In the process, when mean temperature T40 is more than or equal to the first preset temperature T4
s1and be less than or equal to the second preset temperature T4
s2, and t running time of air-conditioner is less than the second preset time t
s2, or mean temperature T40 is less than the first preset temperature T4
s1and t running time of air-conditioner is less than the 3rd preset time t
s3time, namely work as T4
s1≤ T40≤T4
s2and t < t
s2or T40<T4
s1and t < t
s3time, compressor electric motor 40 keeps current state to run the 4th Preset Time B, when reaching the 4th Preset Time B, and reclocking, and the judgement starting a new round.
As the mean temperature T40 of compressor electric motor 40 with when not meeting four kinds of above-mentioned conditions the running time of compressor electric motor 40, then controlling compressor electric motor 40 keeps current state to run the 5th Preset Time C, when reaching the 5th Preset Time C, reclocking, and the judgement starting a new round.
In addition, when compressor electric motor 40 is shut down, before all, the zeros data of record, comprises the timing time t of timer 10, outdoor environment temperature T4 etc.After compressor electric motor 40 starts, start heavy new recorded data.
