Referring to Fig. 2 and Fig. 3, the fast-refrigerating 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 cooling pattern；Fig. 3 is of the invention stays
The curve graph of vehicle air-conditioning raising frequency process of compressor under normal refrigeration mode.
As shown in Fig. 2, step S600 further comprises: working as T in a kind of possible embodiment1< Tao< T2、△T
< A and U >=UnWhen setting up simultaneously, control Air conditioner on car fortune states cooling pattern.Specifically, control compressor is in the first starting
Interior raising frequency is to the first initiation culture；Compressor is controlled from the first initiation culture with the first raising frequency speed raising frequency 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 the second raising frequency speed raising frequency to the
Two oil return frequencies；It controls compressor and the first oil return time was run with the second oil return frequency；Compressor is controlled with the second raising frequency speed
Raising frequency is to maximum operation frequency.
Referring to Fig. 2, for example, T1=28 DEG C, T2=40 DEG C, A=5, Un=20V, first starting the time be 5s, first
The oil return time is 30s, and the first initiation culture is 30Hz, and the first oil return frequency is 60Hz, and the second oil return frequency is 90Hz, compressor
Maximum operation frequency be 120Hz, the first raising frequency speed be 30Hz/s, the second raising frequency speed be 2Hz/s.Work as outdoor environment temperature
When between 28 DEG C -40 DEG C, it was demonstrated that outdoor temperature at this time is suitble to run cooling pattern and the quick raising frequency of compressor, Bu Huiyin
For the too low and unsuitable operation cooling pattern of temperature, compressor overcurrent will not be caused to run because outdoor temperature is too high.Together
Sample, as △ T < 5, 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 cooling pattern, at this time can be by the
One initiation culture, the first raising frequency speed and the second raising frequency speed are set as relatively high parameter value, and by the first oil return time
Shorter duration is set as with the second oil return time.As a result, when entering cooling pattern, control compressor first is quick in 5s
The initiation culture of raising frequency to 30Hz are run；Then from 30Hz with the quick raising frequency of the speed of 30Hz/s to 60Hz, and keep 60Hz's
Frequency runs 30s, to realize while quickly going out cold wind of air conditioner, guarantees the oil return effect of compressor；Next, again with
The raising frequency speed control compressor of 2Hz/s rises to the running frequency of 90Hz from 60Hz, and the frequency is then kept to run 30s, with
Guarantee oil return effect again；Finally, directly rising to maximum operation frequency 120Hz with the raising frequency speed of 2Hz/s, quickly cooling 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 raising frequency speed is set as 30Hz/s, far beyond raising frequency speed in the prior art, significantly reduces the raising frequency time, realizes
Within the very short time can blowing cold air, improve user experience.
Further, in a kind of possible embodiment, step S600 further include: work as T1< Tao< T2, △ T < A and U
≥UnWhen not setting up simultaneously, control Air conditioner on car runs normal refrigeration mode.Specifically, control compressor starts the time first
Interior raising frequency is to the second initiation culture；Compressor is controlled from the second initiation culture with the second raising frequency speed raising frequency to the first oil return frequency
Rate；It controls compressor and the second oil return time was run with the first oil return frequency；Compressor is controlled with third raising frequency speed raising frequency to the
Two oil return frequencies；It controls compressor and the second oil return time was run with the second oil return frequency；Compressor is controlled with third raising frequency speed
Raising frequency is to maximum operation frequency；Wherein, the second initiation culture is greater than the second raising frequency less than the first initiation culture, the first raising frequency speed
Speed, the second raising frequency speed are greater than third raising frequency speed, and the second oil return time was greater than for the first oil return time.
Referring to Fig. 3, for example, T1=28 DEG C, T2=40 DEG C, A=5, Un=20V, first starting the time be 5s, second
The oil return time is 60s, and the second initiation culture is 15Hz, and the first oil return frequency is 60Hz, and the second oil return frequency is 90Hz, compressor
Maximum operation frequency be 120Hz, the second raising frequency speed be 2Hz/s, third raising frequency speed be 1Hz/s.Work as outdoor environment temperature
Less than 28 DEG C or when being greater than 40 DEG C, it was demonstrated that or can be because of the too low and unsuitable operation cooling pattern of temperature or meeting because of room
Outer temperature is too high and compressor overcurrent is caused to run.Similarly, as △ T > 5, it was demonstrated that compressor internal temperature is higher at this time,
Overcurrent operation can be easily caused.As the voltage U < 20V of battery, it was demonstrated that accumulator electric-quantity is short of at this time, if with this voltage
Starting compressor will appear output voltage it is too low and cause compressor overcurrent run.
Therefore, when in above-mentioned decision condition, at least one is invalid, it was demonstrated that conditions present is not suitable for operation cooling pattern, this
When can set the first initiation culture, the first raising frequency speed and the second raising frequency speed to relatively low parameter value, and by
One oil return time and the second oil return time are set as longer duration.As a result, when entering normal refrigeration mode, control is pressed first
Contracting machine initiation culture of quick raising frequency to 15Hz in 5s is run；Then it from 15Hz with the speed raising frequency of 2Hz/s to 60Hz, and protects
The frequency operation 60s of 60Hz is held, to guarantee the oil return effect of compressor；Next, being compressed again with the raising frequency speed control of 1Hz/s
Machine rises to the running frequency of 90Hz from 60Hz, keeps the frequency to run 60s, then to guarantee oil return effect again；Finally, with
The raising frequency speed of 1Hz/s directly rises to maximum operation frequency 120Hz, realizes the complete operation of normal refrigeration mode.
Normal refrigeration mode is run by using above-mentioned control parameter control Air conditioner on car, so that being not suitable for operation quickly cooling
When mode can effective protection Air conditioner on car and compressor, avoid forced service cooling pattern break down.
In alternatively possible embodiment, 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.
Referring to Fig. 4, a kind of possible control process of the application is described.Wherein, Fig. 4 is parking of the invention
The logic chart of the fast-refrigerating control method of air-conditioning.
As shown in figure 4, the driver of haulage truck starts parking under flameout state in a kind of possible implementation process
Air-conditioning detects outdoor environment temperature T at this timeao, compressor delivery temperature TdWith the output voltage U of battery, and exhaust is calculated
Temperature TdWith outdoor environment temperature TaoDifference △ T, be then respectively compared TaoWith T1And T2Between size, the size of △ T and A
And U and UnSize, finally based on judging result control Air conditioner on car run cooling pattern.Specific judgement and control process are such as

60Hz, and the frequency of 60Hz is kept to run 30s, to realize while quickly going out cold wind of air conditioner, guarantee the oil return of compressor
Effect；Next, rising to the running frequency of 90Hz from 60Hz with the raising frequency speed control compressor of 2Hz/s again, then keep
The frequency runs 30s, to guarantee oil return effect again；Finally, the raising frequency speed with 2Hz/s directly rises to maximum operation frequency
120Hz realizes the complete operation of cooling pattern.
2) work as T1< Tao< T2, △ T < A and U >=UnWhen not setting up simultaneously, control Air conditioner on car runs normal refrigeration mode,
That is control compressor initiation culture of quick raising frequency to 15Hz in 5s is run；Then from 15Hz with the speed raising frequency of 2Hz/s to
60Hz, and the frequency of 60Hz is kept to run 60s, to guarantee the oil return effect of compressor；Next, again with the raising frequency speed of 1Hz/s
Degree control compressor rises to the running frequency of 90Hz from 60Hz, and the frequency is then kept to run 60s, to guarantee that oil return is imitated again
Fruit；Finally, the raising frequency speed with 1Hz/s directly rises to maximum operation frequency 120Hz, the complete fortune of normal refrigeration mode is realized
