17 start mechanical compressor 102.When mechanical compressor 102 is unsatisfactory for the second entry condition, machinery
Compressor controller 17 does not start mechanical compressor 102.When signal processor 15 application runs electricity
Dynamic compressor 101 or application run mechanical compressor 102, i.e. signal processor 15 and judge electronic pressure
Contracting machine 101 is unsatisfactory for the first entry condition, judges that mechanical compressor 102 is unsatisfactory for second and opens afterwards
During dynamic condition, anti-closed-loop control device 18 arranges W=W+1, and signal processor 15 applies for fortune again
Row motor compressor 101 or application run mechanical compressor 102, and the value cumulative as W is more than or equal to
During preset value X (such as X=7), anti-closed-loop control device 18 judges that air conditioning system can not normal work
Making, the most anti-closed-loop control device 18 records air conditioning system failure cause, and exits air conditioning system.
The second situation, comparative result is that remaining capacity SOC is less than or equal to the second calibration value Bn；
Signal processor 15 first determines whether whether mechanical compressor 102 meets the second entry condition,
When mechanical compressor 102 meets the second entry condition, now mechanical compress machine controller 17 opens
Dynamic mechanical compressor 102.
When mechanical compressor 102 meets (b2), (b3) and (b4) of the second entry condition, and
When being unsatisfactory for (b1) of the second entry condition, valve positioner 14 controls valve 103 translation bit
Put, and make mechanical compressor 102 turn on air-conditioning duct 104, now mechanical compress machine controller
17 start mechanical compressor 102.
When mechanical compressor 102 meets (b1), (b3) and (b4) of the second entry condition, and
When being unsatisfactory for (b2) of the second entry condition, mechanical compress machine controller 17 does not start machinery pressure
Contracting machine 102, now signal processor 15 judges whether motor compressor 101 meets the first startup again
Condition, when motor compressor 101 meets the first entry condition, motor compressor controller 16
Start motor compressor 101.
When motor compressor 101 meets (a2), (a3) and (a4) of the first entry condition, and
When being unsatisfactory for (a1) of the first entry condition, valve positioner 14 controls valve 103 translation bit
Put, and make motor compressor 101 turn on air-conditioning duct 104, then motor compressor controller
16 start motor compressor 101.When signal processor 15 application run motor compressor 101 or
Application runs mechanical compressor 102, i.e. signal processor 15 and judges that motor compressor 101 is unsatisfactory for
First entry condition, judges when mechanical compressor 102 is unsatisfactory for the second entry condition afterwards, anti-dead
Cycle controller 18 arranges W=W+1, and signal processor 15 is applied for running motor compressor 101 again
Or application runs mechanical compressor 102, when value cumulative for W is more than or equal to preset value X (such as X=7)
Time, anti-closed-loop control device 18 judges air conditioning system cisco unity malfunction, the most anti-endless loop control
Device 18 processed records air conditioning system failure cause, and exits air conditioning system.
The third situation, comparative result is that remaining capacity SOC is less than the first calibration value An, and is more than
Second calibration value Bn；
Signal processor 15 judges whether motor compressor 101 meets the first entry condition or judgement
Whether mechanical compressor 102 meets the second entry condition, opens when motor compressor 101 meets first
During dynamic condition, motor compressor controller 16 starts motor compressor 101；Work as mechanical compressor
102 when meeting the second entry condition, and mechanical compress machine controller 17 starts mechanical compressor 102.
In the present embodiment, the operation principle of the conversion of valve 103 and anti-closed-loop control device 18 with
The content that the first situation above-mentioned is stated with the second situation is identical, and here is omitted.
It is noted that first run when each vehicle runs in view of motor compressor 101
Probability big, therefore after compressor shuts down, lubricating oil is actively assembled to motor compressor
101, run for motor compressor 101 next time and prepare, reduce the switching frequency of compressor.
For valve 103, after the pressure change rate in air-conditioning duct 104 is less than pro, valve
The position of controller 14 conversion valve 103, makes motor compressor 101 lead with air-conditioning duct 104
Logical, though P=1.
Hereinafter will control motor compressor 101 and mechanical compressor to using automotive air-conditioning system 10
102 automobile air-conditioner control method started are described further.Fig. 3 is the air conditioning for automobiles of the present invention
The schematic flow sheet of control method.Incorporated by reference to Fig. 1 and Fig. 3, automobile air-conditioner control method include as
Lower step.
First, air conditioning system starts, and signal processor 15 receives refrigeration requirement, signal processing
Device 15 detects the position of valve 103, and as P=1, signal processor 15 detects motor compressor
Whether 101 meet the first entry condition, when motor compressor 101 meets the first entry condition,
Motor compressor controller 16 starts motor compressor 101, and continues for some time, and makes condensing agent
Run in air-conditioning duct 104 with lubricating oil.As P=2, signal processor 15 detects machinery
Whether compressor 102 meets the second entry condition, when mechanical compressor 102 meets the second trip bar
During part, mechanical compress machine controller 17 starts mechanical compressor 102, and continues for some time, and makes
Condensing agent and lubricating oil run in air-conditioning duct 104.
Then, mode detector 12 detects the car load operational mode of automobile now, and produces one
Organizing the first calibration value An under this pattern and the second calibration value Bn, synchronous signal processor 15 obtains
One group of first calibration value An that the remaining capacity SOC of electrokinetic cell 11, mode detector 12 produce
With the second calibration value Bn compare remaining capacity SOC and the first calibration value An, the second calibration value Bn
Size, signal processor 15 is according to comparative result and the electronic pressure of compressor start condition application
Contracting machine 101 or mechanical compressor 102 start or close；
When remaining capacity SOC is more than or equal to the first calibration value An, signal processor 15 is first
Judge whether motor compressor 101 meets the first entry condition, when motor compressor 101 meets
During one entry condition, motor compressor controller 16 starts motor compressor 101；
When motor compressor 101 meets (a2), (a3) and (a4) of the first entry condition, and
When being unsatisfactory for (a1) of the first entry condition, valve positioner 14 controls valve 103 translation bit
Put, and make motor compressor 101 turn on air-conditioning duct 104, then motor compressor controller
