Referring to Fig. 2 to Fig. 4, the quick heat-production control method of the Air conditioner on car of the application is described in detail.Its
In, Fig. 2 is the curve graph of the Air conditioner on car of the invention raising frequency process of compressor under the first speed heat mode；Fig. 3 is the present invention
Air conditioner on car raising frequency process of compressor under the second speed heat mode curve graph；Fig. 4 is Air conditioner on car of the invention normal
The curve graph of the raising frequency process of compressor under regulation heat pattern.
As shown in Fig. 2, step S500 further comprises: working as T in a kind of possible embodimentd< T, T1< Tao< T2
With U >=UnWhen setting up simultaneously, control Air conditioner on car fortune states speed heat mode.Specifically, control compressor starts the time first
Interior frequency hopping is to the first initiation culture；The raising frequency speed raising frequency that sets from the first initiation culture of control compressor is to the first oil return frequency
Rate；It controls compressor and the first oil return time was run with the first oil return frequency；Compressor is controlled with raising frequency speed raising frequency to second time
Oily frequency；It controls compressor and the first oil return time was run with the second oil return frequency；Compressor is controlled with raising frequency speed raising frequency to most
Big working frequency.
Referring to Fig. 2, for example, T1=-5 DEG C, T2=18 DEG C, T=60 DEG C, Un=20V, the first starting time are 0.2s,
First oil return time was 30s, and the first initiation culture is 60Hz, and the first oil return frequency is 65Hz, and the second oil return frequency is 90Hz, pressure
The maximum operation frequency of contracting machine is 120Hz, and raising frequency speed is 1Hz/s.When outdoor environment temperature is between -5 DEG C -18 DEG C,
Prove that outdoor temperature at this time is suitble to run speed heat mode and the quick raising frequency of compressor, it will not be because of the too high and unsuitable fortune of temperature
Scanning frequency heat pattern will not cause in compressor that cooling machine oil viscosity is high and oil return is difficult because outdoor temperature is too low.Equally
T is worked as on grounddAt 60 DEG C of <, it was demonstrated that compressor internal temperature is moderate at this time, overcurrent will not be caused to transport because internal temperature is too high
Row.As voltage U >=20V of battery, it was demonstrated that accumulator electric-quantity is sufficient at this time, is not in that output voltage is too low and cause to press
The operation of contracting machine overcurrent.
Therefore, when above-mentioned decision condition is set up, it was demonstrated that conditions present is suitble to run speed heat mode, at this time can be by the
One initiation culture, raising frequency speed are set as relatively high parameter value, and start time, the first oil return time and second for first
The oil return time is set as shorter duration.As a result, when entering the first speed heat mode, control compressor first is quick in 0.2s
The initiation culture of frequency hopping to 60Hz are run；Then from 60Hz with the quick raising frequency of the speed of 1Hz/s to 65Hz, and the frequency of 65Hz is kept
Rate runs 30s, to realize while quickly going out hot wind of air conditioner, guarantees the oil return effect of compressor；Next, again with 1Hz/
The raising frequency speed control compressor of s rises to the running frequency of 90Hz from 65Hz, keeps the frequency to run 30s, then with again
Guarantee oil return effect；Finally, directly rising to maximum operation frequency 120Hz with the raising frequency speed of 1Hz/s, the first speed heat mould is realized
The complete operation of formula.
It through inventor's repetition test, observation, analyzes and compares, when using above-mentioned control parameter, it is sufficient to compressor be made to exist
Guarantee under the premise of oil return effect in a short period of time with the biggish quick raising frequency of raising frequency speed to maximum frequency, especially by the
One starting time was set as 0.2s, sets 60Hz for the first initiation culture, substantially reduces prior art center compressor
The starting time realizes the rapidly starting and frequency hopping of compressor, non-far beyond the initiation culture of compressor in the prior art
Hot wind can be blown out in the often short time, improve user experience.
In the case where the first speed heat mode, the maximum operation frequency of compressor can be determined based on following formula:
fmax=k × Tao+b (1)
In formula (1), fmaxFor maximum operation frequency；K is coefficient；TaoFor outdoor environment temperature；B is constant.Wherein k and b
It can be obtained based on fitting experimental data.Certainly, the determination of maximum operation frequency is also based on outdoor environment temperature and maximum
Other relationships of working frequency carry out, and are such as determined based on the fixed correspondence between outdoor environment temperature and maximum operation frequency
Deng.The relationship table between outdoor environment temperature and maximum operation frequency is such as determined based on test, and the table of comparisons is deposited
It is stored in Air conditioner on car, can determine the corresponding maximum operation frequency of outdoor environment temperature using the table of comparisons.
Further, in a kind of possible embodiment, step S500 further include: work as Td< T, Tao≥T2With U >=UnTogether
When Shi Chengli, control Air conditioner on car runs the second speed heat mode.Specifically, control compressor raising frequency within the second starting time
To the second initiation culture；Compressor is controlled with the direct raising frequency of raising frequency speed to the second oil return frequency；Compressor is controlled with second time
Oily frequency ran for the second oil return time；Compressor is controlled with raising frequency speed raising frequency to maximum operation frequency；Wherein, the second starting frequency
Rate was greater than for the first oil return time less than the first initiation culture, the second oil return time.
Referring to Fig. 3, for example, T1=-5 DEG C, T2=18 DEG C, T=60 DEG C, Un=20V, the first starting time are 5s, the
Two oil return times were 60s, and the second initiation culture is 40Hz, and the second oil return frequency is 90Hz, and the maximum operation frequency of compressor is
120Hz, raising frequency speed are 1Hz/s.When outdoor environment temperature is greater than between 18 DEG C, it was demonstrated that outdoor temperature at this time is higher, and
And the viscosity of the cooling machine oil inside compressor is also smaller, therefore is suitble to operation speed heat mode and the quick raising frequency of compressor.Equally
T is worked as on grounddAt 60 DEG C of <, it was demonstrated that compressor internal temperature is moderate at this time, overcurrent will not be caused to transport because internal temperature is too high
Row.As voltage U >=20V of battery, it was demonstrated that accumulator electric-quantity is sufficient at this time, is not in that output voltage is too low and cause to press
The operation of contracting machine overcurrent.
Therefore, when above-mentioned decision condition is set up, it was demonstrated that conditions present is suitble to run speed heat mode, at this time can be direct
Cancel the first oil return frequency, but after compressor start, directly by the second initiation culture raising frequency to the second oil return frequency.By
This, when entering the second speed heat mode, control compressor initiation culture of quick raising frequency to 40Hz in 5s first is run；Then
The first direct raising frequency of oil return frequency is skipped to 90Hz from 40Hz with the speed of 1Hz/s, and the frequency is kept to run 60s, to realize
While quickly going out hot wind of air conditioner, guarantees the oil return effect of compressor；Finally, with the raising frequency speed raising frequency of 1Hz/s to most
Big working frequency 120Hz, realizes the complete operation of the second speed heat mode.
It through inventor's repetition test, observation, analyzes and compares, when using above-mentioned control parameter, it is sufficient to compressor be made to exist
In a short period of time with the biggish quick raising frequency of raising frequency speed to maximum frequency under the premise of guarantee oil return effect, especially cancel
Compressor substantially reduces starting and the raising frequency time of prior art center compressor after the stop of the first oil return frequency, real
The rapidly starting of existing compressor, can blow out hot wind within the very short time, improve user experience.
In the case where the second speed heat mode, since outdoor environment temperature is higher at this time, the maximum functional of compressor
Frequency can be determined based on following formula:
fmax=(k × Tao+b)×(T2/Tao) (2)
In formula (2), fmaxFor maximum operation frequency；K is coefficient；TaoFor outdoor environment temperature；B is constant；T2It is second
Temperature threshold；TaoFor outdoor environment temperature.Wherein k and b can be obtained based on fitting experimental data.Certainly, maximum operation frequency
Determination be also based on other relationships of outdoor environment temperature and maximum operation frequency and carry out, such as based on outdoor environment temperature with
Fixed correspondence determination between maximum operation frequency etc..Outdoor environment temperature and maximum functional frequency are such as determined based on test
Relationship table between rate, and the table of comparisons is stored in Air conditioner on car, outdoor ring can be determined using the table of comparisons
The corresponding maximum operation frequency of border temperature.
Further, in a kind of possible embodiment, step S500 further include: when above-mentioned two situations are different
When establishment, control Air conditioner on car runs conventional heating mode.Specifically, control compressor within the second starting time raising frequency to the
Three initiation cultures；Compressor is controlled from third initiation culture with raising frequency speed raising frequency to third oil return frequency；Control compressor with
Third oil return frequency ran for the second oil return time；Compressor is controlled with raising frequency speed raising frequency to the second oil return frequency；Control compression
Machine ran for the second oil return time with the second oil return frequency；Compressor is controlled with raising frequency speed raising frequency to maximum operation frequency；Wherein,
Third initiation culture is less than the second initiation culture, and third oil return frequency is less than the first oil return frequency.
Referring to Fig. 4, for example, T1=-5 DEG C, T2=18 DEG C, T=60 DEG C, Un=20V, the first starting time are 5s, the
