Control part 110, according to the data inputted by remote controller 3 or input part 170, is set running and controls to make air regulator action, and exporting corresponding operating state by display part 180.The transmitting-receiving of control part 110 pairs of off-premises stations and indoor set data each other controls, and makes according to running set action, and according to operation mode, the power consumption controlling air regulator is no more than a reference value of regulation when being set as generator mode.
Especially, when being set as generator mode by remote controller 3 or input part 170, control part 110 is with the maximum power consumption value of air regulator for benchmark sets a reference value of power consumption in the scope of about 60% to 80%, and the power consumption controlling air regulator does not exceed a reference value of set power consumption.Now, a reference value can be changed according to the capacity of air regulator, maximum power consumption value.
In addition, control part 110, according to the characteristic of inputted power supply, automatically can identify generator power supply when being connected with generator, and be set as generator mode.Such as, can the waveform of analytical voltage, judge whether to be connected with generator according to total harmonic distortion (THD, TotalHarmonicDistortion).
Here, generator mode refers to, when the power supply being supplied to air regulator be low-voltage or variation in voltage large, or when generator capacity is low capacity, even air regulator to be set as the pattern that the input power of instability also can operate continuously.Such as, when air regulator is connected with the generator of low capacity, or when supplied power supply is low-voltage, generator mode can be set as.
If be set as generator mode, then control part 110 is based on the voltage inputted by voltage detection department 140, the performance number that air regulator consumes is calculated according to the capacity of air regulator, loading level, and by the performance number calculated compared with a reference value set, the power consumption controlling air regulator thus does not exceed a reference value of regulation.
If the power consumption calculated increases, then control part 110 controls drive division 130 increases to make the operating frequency step-down of compressor to limit power consumption, if power consumption reduces, then control part 110 makes the operating frequency of compressor uprise to improve cooling and warming performance.
The transport maximum frequency that namely control part 110 can be operated by the maximum of the operating frequency changing compressor, carrys out limit compression machine not with frequency run more than transport maximum frequency.Such as, when the transport maximum frequency of compressor is 100hz, 50hz is set as transport maximum frequency by control part 110, makes compressor not to exceed the frequency run of 50hz.Now, do not exceed in the operating frequency range of a reference value at the power consumption making to calculate, setting transport maximum frequency.
Fig. 4 shows the block diagram of the structure relevant with the action control of air regulator of the present invention.As shown in Figure 4, power supply unit 120 comprises power input part 121, rectification part 122, DC link section (DClink) 123.
The power supply of industrial power 20 or generator 10 is connected with air regulator, to power input part 121 supply power.Rectification part 122 carries out rectification to inputted power supply, and DC link section 123 is to the smoothing process of rectified power supply.Thus, the AC power inputted is converted to dc source.
Drive division 130 comprises the frequency converter 131 for making compressor 191 drive.In addition, the first fan driving section (not shown) for making outdoor fan 192 or indoor fan 193 drive and the second fan driving section (not shown) is also comprised.Now, compressor 191, outdoor fan 192, indoor fan 193 are for acting on the load of power supply.
Frequency converter 131 for the dc source after the rectification of power supply unit 120 and smoothing processing is converted to AC power and the motor being supplied to compressor 191 to make compressor action.
In addition, outdoor fan 192 is connected with drive division 130, when motor is by spinning movement thereupon during the first fan driving section action.Outdoor fan 192 is for being expelled to outside by the air in outdoor heat converter 194 heat exchange.In addition, indoor fan 193 at motor by spinning movement thereupon during the second fan driving section action, for the air in indoor heat converter 195 heat exchange is expelled to indoor.
The voltage of voltage detection department 140 pairs of DC link section 123 measures and inputs to control part 110 (202).
Because the voltage of DC link section 123 changes according to the load condition of power supply, so control part 110 controls drive division 130 based on the voltage of DC link section 123.
Control part 110, identifies (201) to set generator mode to generator power supply automatically, or sets generator mode according to the data 206 received from remote controller 3.
In addition, when being set as generator mode, control part 110 is according to the performance number calculated based on potentiometer, and the frequency converter 131 to drive division 130 applies control command (203) and controls compressor 191, and limiting power consumption thus increases.Drive division 130 changes the operating frequency of compressor 191 according to the control command of control part 110, makes compressor with the operating frequency action of setting.
Now, when air regulator operates, frequency converter 131 controls compressor 191 with the action of initial operation frequency, and along with the increase of load, the operating frequency of compressor 191 is also uprised.When being set as generator mode, even if the load of air regulator increases, the operating frequency of compressor 191, also according to the control command of control part 110, controls as being no more than prescribed level by frequency converter 131.
The operating frequency that control part 110 controls compressor 191 changes according to the performance number calculated, if performance number is within the scope of setting, then in the mode maintaining the operating frequency of compressor, control command is applied to drive division 130.
In addition, control part 110 controls power consumption on one side as described above and does not exceed a reference value, while judge the load condition of power supply 10 or power supply 20 according to the voltage 202 of DC link section 123, control thus to act on the compressor 191 of power supply, outdoor fan 192 or indoor fan 193 (204,205) as load, carry out regulating action in the load of power supply.
Fig. 5 is the figure that the operating frequency adopted the power consumption control in order to air regulator of the present invention controls to be described time institute's reference.
With reference to Fig. 5, when being set as generator mode, control part 110 is with a reference value of the maximum power consumption of air regulator for benchmark setting power consumption.Such as, if the air regulator of 1KW, then 600W can be set as a reference value (TG1) by control part 110.
The a reference value of setting and the performance number calculated compare by control part 110, and control performance number does not exceed the 600W as a reference value.Now, the mode that control part 110 does not exceed a reference value with performance number also sets the second a reference value (TG2) in addition.When a reference value as above (hereinafter, referred to first reference value (TG1)) is for 600W, the second a reference value (TG2) can be set as about 500W.
When the power consumption calculated belongs to the following first area A of the second a reference value (TG2), control part 110 can not make the operating frequency of compressor 191 uprise by other restrictions.If the operating frequency of compressor 191 uprises, then the power consumption of air regulator also correspondingly increases (S11).
Control part 110 calculates power consumption based on the voltage measured, if the power consumption calculated reaches the second a reference value (TG2), then control command is applied to drive division 130 to control compressor 191.Now, drive division 130 is according to the control command of control part 110, and the operating frequency of limit compression machine 191 uprises further.
When power consumption belongs to the second area B between first reference value (TG1) and the second a reference value (TG2), drive division 130 maintains the operating frequency of compressor 191.
On the other hand, when power consumption is first reference value (TG1), control part 110 makes consumed power consumption reduce (S12) by making the operating frequency step-down of compressor 191.Now, control part 110 controls power consumption and does not exceed first reference value (TG1), if beyond first reference value (TG1), then controls the operating frequency step-down of compressor 191.
When by making the operating frequency step-down of compressor 191 make power consumption reduce, cooling and warming performance also can reduce, so when power consumption belongs to first area A, the operating frequency that control part 110 can control compressor 191 uprises again.
Now, the transport maximum frequency that namely control part 110 changes the operating frequency of compressor 191 maximum according to power consumption can operate, limit compression machine 191 can not with frequency run more than transport maximum frequency thus.Thus, control part 110 can make the power consumption of air regulator not exceed a reference value.
Fig. 6 A and Fig. 6 B shows the ideograph of the change of the power consumption based on pattern setting of air regulator of the present invention.
Fig. 6 A shows the figure of the change of power consumption when air regulator is connected with generator and usually operates, and Fig. 6 B shows the figure of the change of power consumption when being set as generator mode.
As shown in Figure 6A; when the air regulator be connected with generator starts running; because generator capacity is limited, so uprise along with the power consumption of air regulator and make generator be in overload condition, protection circuit is made to start to make air regulator stop action.
Air regulator is according to restarting running after the protection circuit logic standby stipulated time, but generator capacity is still limited, thus repeatedly start after stop and again restarting.Such phenomenon can make user feel uneasy, also can become the reason of generator failure, and air conditioner can be made to be damaged.
On the other hand, as shown in Figure 6B, when the air regulator be connected with generator is set as generator mode, control part 110 limits power consumption at the operating frequency of the time control compressor 191 that starts running, so the power consumption of air regulator increases setting according to a reference value of setting, then maintain the value (S2) of about 60% of maximum power consumption.
Now, if air regulator is connected with common industrial power, so, if air regulator starts running, then compressor 191 carrys out action according to running setting, and power consumption increases in time.When compressor 191 operates with highest level, as shown in the figure, air regulator maintains maximum power consumption (S1).
In the present invention, with the maximum power consumption under the common operational situation of such air regulator for benchmark sets generator mode, the power consumption of air regulator is restricted to maximum power consumption 60 to 80% operate.
Fig. 7 shows the power consumption based on pattern setting and the curve map of operating frequency of air regulator of the present invention.Fig. 7 shows the operating frequency that is set as the compressor of generator mode when operating on the generator that air regulator is connected to separately 1KWVA and power consumption over time.
As shown in Figure 7, if air regulator is connected with generator and starts running, then the operating frequency (S21) of compressor 191 uprises.The power consumption (S22) of air regulator also uprises thereupon.
When setting generator mode, control part 110 sets a reference value (first reference value, S23) of power consumption.Now, with the maximum power consumption of air regulator for benchmark, a reference value can be set in the scope of 60 to 80%.
Now, control part 110 sets generator mode according to the data of remote controller 3 or input part 170.According to different situations, the power supply that control part 110 also can judge to be supplied to air regulator by other detecting unit is generator power supply or industrial power.When supply generator power supply, control part 110 according to the detection signal of detecting unit, can be automatically made generator mode.
Control part 110 calculates the power consumption of air regulator according to the voltage measured in operation process, and the power consumption controlled correspondingly as calculating does not exceed a reference value.
As mentioned above, control part 110 sets second a reference value less than a reference value, if the power consumption calculated exceeds the second a reference value, dislikes and applies control command to control the operating frequency of compressor 191 to drive division 130.
If power consumption is more than the second a reference value and be less than a reference value (S23, first reference value), then belong to second area B, so drive division 130 maintains the operating frequency of current compressor 191 in Fig. 5 as above.But when being judged as that power supply is in overload condition, control part 110 does not exceed in the scope of a reference value at power consumption, controls the operating frequency of compressor 191.
Thus, the operating frequency of compressor 191 maintains setting, though some variation because of the variation of input voltage or load of the value of power consumption, can not exceed a reference value of setting.And, inputted power supply and the overload condition of generator power supply can be removed.
Therefore, air regulator can not shut down ground long time running, and can maintain the cooling and warming performance of regulation.
Fig. 8 shows the figure of the remote controller of air regulator of the present invention.
As shown in Figure 8, the remote controller 3 of air regulator has multiple key 220, also has display part 210.The data inputted by multiple key 220 transfer to indoor set 1 from remote controller 3, and indoor set sets according to the running of received data to air regulator.
At the display part 210 of remote controller 3, show the setting of present air adjuster, also show and input corresponding data or menu with key.
If have selected generator mode key 221 in multiple key 220, then indoor set 1 receives corresponding data to set generator mode, and sets a reference value of power consumption as described above.Thus, the running of off-premises station 2 pairs of compressors controls.
Fig. 9 shows the flow chart of the control method of air regulator of the present invention.
As shown in Figure 9, air regulator is connected with power supply (S310), and the operation mode of setting air adjuster (S320).Now, air regulator accepts the supply of power supply from generator.
The running setting of input air adjuster, sets pattern and the generator mode (S320) of the power supply be connected with air regulator.

On the other hand, if power consumption is more than the second a reference value, then power consumption and first reference value compare (S390) by control part 110.
If power consumption is more than the second a reference value and is less than first reference value, then control part 110 applies control command to drive division 130 and maintains currency (S410) to make the operating frequency of compressor 191.
In addition, if power consumption reaches first reference value, then control command is applied to drive division 130 to make the operating frequency step-down (S400) of compressor by control part 110.Now, the power consumption that control part 110 controls air regulator does not exceed first reference value figure, if but according to circumstances beyond first reference value, then make the operating frequency step-down of compressor immediately, thus make power consumption reduce.
Until receive the order that shuts down (S420), control part 110 from voltage detection department 140 periodically receiver voltage calculate power consumption, control the operating frequency (S350 to S410) of compressor 191 thus.
If receive the order that shuts down, then control part 110 makes running stop (S430).
Thus, air regulator controls power consumption and does not exceed set a reference value and operate, so connected power supply and generator can be prevented to be in overload condition, thus can realize continuous running.
