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, see Fig. 1, Fig. 2; Comprise 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 driving engine, the present invention is also provided with pure electric frequency-changeable compressor in car body, this pure electric frequency-changeable compressor connects via relay is corresponding with the storage battery (electric power supply source) in this automobile, this relay is also corresponding with air-conditioner controller to be electrically connected, and described pure electric frequency-changeable compressor is also corresponding with air-conditioner controller to be electrically connected; Further, also correspondence is provided with the tachogen for detecting this engine speed on the engine, and this tachogen is also corresponding with air-conditioner controller to be electrically connected; And described driving engine is electrically connected via Engine ECU is corresponding with air-conditioner controller; In the compartment of the present invention in car body, also correspondence is provided with the corresponding temperature sensor connected of multiple and described air-conditioner controller, to detect the temperature in compartment in real time.Simultaneously, the present invention also comprises interlocking electromagnetic valve one, interlocking electromagnetic valve two, shown in 2, the inlet end of described interlocking electromagnetic valve one and interlocking electromagnetic valve two respectively via correspondence refrigerant pipe respectively with pure electric frequency-changeable compressor, mechanical compressor is corresponding is communicated with, and interlock electromagnetic valve one and the outlet side interlocking electromagnetic valve two and be communicated with via the refrigerant pipe of correspondence is corresponding with the air ventilation passage in compartment.Meanwhile, described Engine ECU is also corresponding with the entire car controller (carrying in automobile) of this new-energy automobile connects; And be also provided with the Liquid Crystal Display that connect corresponding to described entire car controller at the gauge panel place of steering position to show the information such as temperature, refrigeration mode (pure electrician's operation mode or machine work pattern) in compartment.
Principle of work of the present invention is as follows:
Controlled by the air-conditioner controller of operator's compartment, power-on, meanwhile, interlocking electromagnetic valve one and interlocking electromagnetic valve two get involved work, when engine starting, air-conditioner controller receives the tach signal that Engine ECU sends, and when the rotating speed of driving engine reaches setting value, air-conditioner controller controls the power-transfer clutch adhesive of mechanical compressor, mechanical compressor works, realize refrigeration, now interlock electromagnetic valve two and open input cold air, interlocking electromagnetic valve one is closed; And now pure electric frequency-changeable compressor enters closed condition automatically, now interlock the coolant connecting tube road that electromagnetic valve one prevents 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.When temperature sensor detects that vehicle interior temperature reaches design temperature or when not needing to use motor-powered vehicle to advance, air-conditioner controller sends instruction after receiving this signal simultaneously, mechanical compressor is made to quit work (or engine stop work), interlocking electromagnetic valve two is closed, simultaneously, start pure frequency-changeable compressor to start working, maintain vehicle interior temperature supply by pure frequency-changeable compressor, realize the object of sustainable refrigeration.
When the idling start and stop of car amount, when low engine speed is rotated, (mechanical compressor is when the less input of power, its refrigeration is not good, even can not work), pure electric frequency-changeable compressor work can be switched to voluntarily according to the rotating speed of driving engine, to reduce the high-power output of driving engine, reach the object of fuel saving, avoid the high-performance output of driving engine to cause the waste of fuel.Meanwhile, in above-mentioned mode of operation, air-conditioner controller can according to the tach signal of driving engine, by the horsepower output of the real-time control driving engine of Engine ECU, avoids high-power output to cause waste.Simultaneously, the temperature signal that Engine ECU horsepower 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, being convenient to steerman can know corresponding state information in real time.
Although; what embodiments of the invention were announced is preferred embodiment; but be not limited thereto; 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 change; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
