Description
Technical field
The present invention relates to new-energy automobile field, be specifically related to a kind of new-energy automobile with Dual-energy source air-conditioning.
Background technology
Along with the scarcity of energy resources, new energy vehicle is assented and is given birth to, as oil and electricity hybrid vehicle, and gas-electricity power combined car etc., no matter how new-energy automobile develops, in car, use air-conditioning refrigeration system to be absolutely necessary, the especially city bus equipment that is more absolutely necessary, also belongs to one of standard configuration that vehicle manufactures. The current air-conditioning mating on integral new-energy passenger is mainly taking the machine driving air-conditioning that only arranges (adopting mechanical compressor refrigeration modes) as main, its major function is as follows: first, by the detection signal of temperature sensor, pass to air-conditioner controller, air-conditioner controller sends refrigeration signal again to entire car controller, with by the start and stop of vehicle control unit controls engine, realize the automatic control to compressor. In the time that vehicle interior temperature reaches the temperature of setting on air-conditioning panel, air-conditioner controller control mechanical compressor can quit work automatically; And in the time there is difference between vehicle interior temperature and design temperature, compressor carries out work (its essence is that air-conditioner controller is by controlling the clutch adhesive of compressor, realize and carry out power delivery with engine, realize refrigeration with this) again. The second, power ascension function while realizing engine idle. In the time that engine needs idling to start, air-conditioner controller can transmit signal to engine according to the requirement of engine output, promotes the power of engine, thereby meets the instructions for use that engine idle starts. In the time that idling starts, as in automobile when power shortage, need to use engine start, now, requirement when a power part for engine should meet automobile starting, also will meet the job requirement of mechanical compressor, this will improve the power output of engine greatly simultaneously, directly causes the cost of fuel to increase; The 3rd, when in vehicle operating, when power stage switches to pure electric drive by motor driven, cold air in compartment can only be worked by evaporation fan, to promote car internal cooling airflow moving, impel passenger to be unlikely to obviously (now, compressor is not worked) of temperature sensation from sense organ; The 4th, the temperature in car can have a greater change for a long time, as need reduce the temperature in car, also needs power stage to switch to motor driven (now must by engine start) by pure electric drive; After vehicle interior temperature gos up, feed back to entire car controller and air-conditioner controller by temperature sensor signal, entire car controller sends instruction, ato unit, and then realize refrigeration. The adhesive action that mechanical compressor clutch is reciprocal, immediate current and power consumption are all a kind of excessive wastings of resources.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment 1: a kind of new-energy automobile with Dual-energy source air-conditioning, referring to Fig. 1, Fig. 2; Comprise that car body, air-conditioner controller (carrying in automobile), correspondence are arranged in described car body, the mechanical compressor that be in transmission connection corresponding to engine, the present invention is also provided with pure electric frequency-changeable compressor in car body, this pure electric frequency-changeable compressor is via relay and the corresponding connection of battery (supply of electric power source) in this automobile, this relay is electrical connection corresponding to air-conditioner controller also, the also electrical connection corresponding to air-conditioner controller of described pure electric frequency-changeable compressor; Further, on engine, also correspondence is provided with the speed probe for detection of this engine speed, and this speed probe is electrical connection corresponding to air-conditioner controller also; And described engine is via Engine ECU electrical connection corresponding to air-conditioner controller; In the compartment of the present invention in car body, go back the corresponding temperature sensor that is provided with the corresponding connection of multiple and described air-conditioner controller, to detect in real time the temperature in compartment. Simultaneously, the present invention also comprises interlocking magnetic valve one, interlocking magnetic valve two, shown in 2, the inlet end of described interlocking magnetic valve one and interlocking magnetic valve two respectively via corresponding refrigerant pipe respectively with pure electric frequency-changeable compressor, corresponding connections of mechanical compressor, and interlocking magnetic valve one and the outlet side that interlocks magnetic valve two are via corresponding refrigerant pipe and the corresponding connection of gas communication passage in compartment. Meanwhile, described Engine ECU also with the corresponding connection of entire car controller (carrying in automobile) of this new-energy automobile; And the liquid crystal display that is also provided with connection corresponding to described entire car controller at the instrument board place of steering position is to show the information such as temperature, refrigeration mode (pure electrician's operation mode or machine work pattern) in compartment.
Operation principle of the present invention is as follows:
By the air-conditioner controller control of driver's cabin, power-on, meanwhile, interlocking magnetic valve one and the two intervention work of interlocking magnetic valve, in the time of engine start, air-conditioner controller receives the tach signal that Engine ECU sends, in the time that the rotating speed of engine reaches setting value, and the clutch adhesive of air-conditioner controller control mechanical compressor, mechanical compressor work, realize refrigeration, now interlock magnetic valve two and open input cold air, interlocking magnetic valve one cuts out; And now pure electric frequency-changeable compressor enters closed condition automatically, now interlock the coolant connecting tube road that magnetic valve one has stoped pure electric frequency-changeable compressor, make it pipeline refrigerant without pressure, realize mechanical compressor and the operation of the pipeline that communicates, realize refrigeration in car. In the time that temperature sensor detects that vehicle interior temperature reaches design temperature or while not needing to use motor-powered vehicle to advance, air-conditioner controller sends instruction after receiving this signal simultaneously, make mechanical compressor quit work (or engine stop work), interlocking magnetic valve two cuts out, simultaneously, start pure frequency-changeable compressor and start working, maintain vehicle interior temperature supply by pure frequency-changeable compressor, realize the object of sustainable refrigeration.
In the time of the start and stop of car amount idling, when low engine speed is rotated, (mechanical compressor is in the time of the less input of power, its refrigeration is not good, even can not work), can switch to voluntarily pure electric frequency-changeable compressor work according to the rotating speed of engine, to reduce the high-power output of engine, reach the object of fuel saving, avoid the powerful output of engine to cause the waste of fuel. Meanwhile, in above-mentioned duty, air-conditioner controller can, according to the tach signal of engine, by the power output of the real-time control engine of Engine ECU, avoid high-power output to cause waste. Simultaneously, the temperature signal that Engine ECU power output signal and air-conditioner controller receive and refrigeration mode information also can transfer to the entire car controller of this automobile, and and then transfer on instrument display and shown, be convenient to driver and can know in real time corresponding state information.
Although; what embodiments of the invention were announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily, according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
