Description
Technical field
The present invention relates to the air-conditioning technical field of automobile, more particularly to a kind of automobile double air-conditioner control system and method.
Background technology
Automotive air-conditioning system, which is used for realization, to freeze air in a car compartment, is heated, being taken a breath and air purification, it can be
Passenger provides comfortably environment by bus, therefore people are higher and higher to the performance requirement of air-conditioning system.
Light passenger train's class vehicle at present, two evaporators and the organization plan of a condenser that the double air-conditioning systems in part use,
That is " double steaming Dan Leng " systems.
In double air-conditioning systems, in order to realize the independent control of forward and backward evaporator, two solenoid valves, Ke Huke are configured with
To control two solenoid valves respectively as needed, to achieve the purpose that to control forward and backward evaporator respectively, specific air-conditioning system is followed
Ring figure can refer to shown in Fig. 1.
In double air-conditioning systems, air-conditioning after client is used alone and the situation of air-conditioning is very rare therefore double before being not turned on
Do not add solenoid valve in air-conditioning system in the refrigerating circuit of preceding air-conditioning mostly, and individually added in the refrigerating circuit of rear air-conditioning
Solenoid valve, for realizing the independent control to rear air-conditioning, the circulation figure of specific air-conditioning system can refer to shown in Fig. 2.

Air-conditioning switching, the adjusting of changes in temperature air quantity, interior circulation barrier foul atmosphere or outer circulation supplement fresh air afterwards.
It should be noted that display screen is additionally provided with console, the working status for air-conditioning before and after real-time display.
Specifically, A/C buttons, REAR buttons, MODE buttons, OFF buttons, the rotation with F marks are additionally provided with console
Button, the knob with R marks, the control to forward and backward air-conditioning can be realized by the above-mentioned button on operating console and knob.
Further, A/C buttons realize the control to compressor；Knob with F marks can be realized total to preceding air-conditioner host
The adjusting of Cheng Zhongqian blower air quantities；Knob with R marks can be realized to rear air blower in rear air conditioner top evaporator assembly
The adjusting of air quantity；OFF buttons are used for realization the closing to forward and backward air-conditioning；MODE buttons can realize forward and backward air-conditioning work pattern
Switching, the operating mode ratio is if any refrigeration, heating, air-supply, dehumidifier etc..
It is to the adjusting of preceding blower air quantity in preceding air-conditioner host assembly or the steaming of rear air conditioner top that REAR buttons, which are used to identify,
Whether the adjusting of blower air quantity is effective after sending out in device assembly, such as, when REAR buttons are lighted, rear air conditioner top evaporator assembly
In after blower air quantity adjusting it is effective；When REAR buttons are non-lit up, the adjusting of preceding blower air quantity in preceding air-conditioner host assembly
Effectively.
With reference to the control unit on console, the concrete operations of automobile double air-conditioner control system of the embodiment of the present invention are as follows：
When the knob identified with F is not located at 0, start A/C, preceding air-conditioning is started to work, if the knob position at this time with R marks
When 0, the second speed adjusting module gives air-conditioner controller one feedback signal, after air-conditioner controller receives the feedback signal, control
The fast module output 6.7V voltage signals of system second, so that rear air blower starts, with minimum air quantity mode of operation, to control at this time
Blower air quantity illustrates after the display screen of platform can accordingly show " REAR " character and a lattice.Air blower is minimum after needing to exit
During air quantity operating mode, following any operation can be carried out and realized：1. operating A/C buttons, close compressor；2. pass through band R
Blower air quantity size after the knob of mark is adjusted, air blower works according to actual air volume size requirement afterwards at this time.
In conclusion double air-conditioner control systems provided in an embodiment of the present invention, can using the arrangement of " double steamings are double cold "
Effectively to improve the demand of the big refrigerating capacity of system；The present invention only passes through the logic journey to air-conditioner controller without solenoid valve control
Sequence is set, specifically, when the rear air blower of current air-conditioning unlatching, compressor operating and rear air-conditioning is not opened, after control
