Further, since heat pump air conditioner circulation loop is utilized from engine and is discharged in crew module's heating for fuel vehicle Exhaust gas heat so that heating operations realize while being utilized atmospheric heat and the heat of engine exhaust is heated, To greatly accelerate heating speed, heating effect is improved.
In addition, it is necessary to which explanation, is to be applied to the present invention to appoint by the automotive thermal tube reason method provided in this present embodiment It anticipates automotive thermal tube reason system, thus the not technical detail of detailed description in the present embodiment, reference can be made to the present invention is arbitrarily implemented Automotive thermal tube provided by example manages system, and details are not described herein again.
Further, as shown in fig. 6, propose automotive thermal tube reason method of the present invention based on first embodiment second implements Example, in the present embodiment, has carried out specific refinement to made operation in step S30 according to the coolant temperature of engine, in detail See step S30' adjusted.
In order to make it easy to understand, being specifically described below referring to Fig. 6:
Step S30', when the coolant temperature of the engine is not more than preset temperature threshold, first heat pump is empty It adjusts circulation loop to absorb heat from outside air and waste gas residual heat recycling water route, is crew module and the engine of the fuel vehicle Cooling system heating;When the coolant temperature of the engine is greater than preset temperature threshold, the second heat pump air conditioner circulation Circuit absorbs heat from outside air and waste gas residual heat recycling water route, is that the crew module of the fuel vehicle heats.
Specifically, the concrete structure schematic diagram of the automotive thermal tube reason system provided by Fig. 3 is it can be found that described first Most of components in heat pump air conditioner circulation loop and the second heat pump air conditioner circulation loop are to be overlapped, i.e., same zero Component is the composition for taking part in the first heat pump air conditioner circulation loop, has also assisted in the second heat pump air conditioner circulation loop It constitutes.Thus, it is not more than preset temperature threshold in the coolant temperature of the engine, such as at 80 DEG C, it is described in order to guarantee First heat pump air conditioner circulation loop can work normally, and need to be arranged described first in the first heat pump air conditioner circulation loop Electrically-controlled valve, second electrically-controlled valve and the 5th electrically-controlled valve are opened, the third electrically-controlled valve, the 4th electrically-controlled valve and described 6th electrically-controlled valve is closed, and the wind deflector is closed upwards, so that the first heat pump air conditioner circulation loop can be from the external world The recycling of air and waste gas waste heat absorbs heat in water route, is crew module and the engine-cooling system heating of the fuel vehicle.
Correspondingly, when the coolant temperature of the engine is greater than preset temperature threshold, in order to guarantee second heat Pump Air-conditioning Cycle circuit can work normally, and need to be arranged described first automatically controlled in the second heat pump air conditioner circulation loop Valve, second electrically-controlled valve and the 5th electrically-controlled valve are opened, the third electrically-controlled valve, the 4th electrically-controlled valve and the described 6th Electrically-controlled valve is closed, and the wind deflector is closed upwards, so that the second heat pump air conditioner circulation loop is from outside air and gives up The recycling of gas waste heat absorbs heat in water route, is that the crew module of the fuel vehicle heats.
In addition, it is noted that the automobile heat has been changed system and has also been wrapped due in order to accelerate to heat speed as far as possible Include engine water route circulation loop.
And the major function of engine water route circulation loop is the coolant temperature in the engine greater than default When stable threshold, cooperate the second heat pump air conditioner circulation loop, is heated for the fuel vehicle, to promote multiplying for the fuel vehicle The effect of member cabin heating.
Further, in order to control the water of the first water pump and the second water pump in the automotive thermal tube reason system, Yi Jisuo The air pressure in the second plate heat exchanger and the third plate heat exchanger is stated, the automotive thermal tube reason system provided in the present embodiment is also Including degasification water pipe.
Specifically, the degasification water pipe substantially needs to include expansion kettle, water pipe and degasification pipeline.
Correspondingly, in practical applications, the expansion kettle needs to connect with the water pipe and the degasification pipeline respectively It connects, to control the water of first water pump and second water pump by the water pipe, passes through the degasification pipeline Control the air pressure in second plate heat exchanger and third heat exchanger.
It should be noted that for ease of description, the above-mentioned operating process provided is specifically with fuel vehicle in driving process In, when the instruction of the air-conditioner controller output in fuel vehicle is heating mode, the coolant temperature difference of the engine of fuel vehicle When being greater than preset temperature threshold and being not more than preset temperature threshold, the operating mode of the automotive thermal tube reason system.
Further, since in practical applications, in a heating mode, air-conditioner controller is also possible to output demisting instruction, thus In order to make the automotive thermal tube provided in the present embodiment reason system can be realized defrosting function, demisting is received in a heating mode and is referred to When enabling, first electrically-controlled valve, third electrically-controlled valve, the 4th electrically-controlled valve, the 6th electrically-controlled valve and the first water pump are specifically set and opened, institute It states the second electrically-controlled valve and the 5th electrically-controlled valve is closed, the wind deflector is closed upwards, so that by electric expansion valve section Low temperature and low pressure liquid refrigerant after stream has been split a part of flow to the First Heat Exchanger, and then by the First Heat Exchanger The temperature for flowing into air is reduced, so that the part vapor in air is condensed, so that having reached reduces air absolute humidity Effect, and then realize defogging effect.
In addition, in practical applications, during enforcement, the air-conditioner controller is also possible to export and change the fuel vehicle Gas mode instruction.
Correspondingly, in such a mode, the exhaust Electrocontrolled tee valve needs to open left side gas outlet, closes right side outlet Mouthful, i.e., opening catalyst converter to silencer direct channel so that engine exclude exhaust gas without the first plate heat exchanger, and It is to be expelled directly out outside fuel vehicle.
In addition, in such a mode, the clutch of the compressor needs to disconnect, first water pump needs to close, described Wind deflector needs to close downwards, so that outside air is directly entered car.
In addition, in practical applications, during enforcement, the air-conditioner controller is also possible to that system can be exported the fuel vehicle Cold mode instruction.
Correspondingly, in such a mode, the circulation loop of the automotive thermal tube reason system work specifically: the compressor -> The commutator -> second heat exchanger -> electric expansion valve -> First Heat Exchanger -> commutator -> described Gas-liquid separator -> the compressor, the specific linking relationship about each components in the circulation loop can know in conjunction with Fig. 3, Details are not described herein again.
However, it should be understood that in order to guarantee that above-mentioned circulation loop can work normally, in practical applications, specifically It needs to be arranged first electrically-controlled valve, the third electrically-controlled valve, the 4th electrically-controlled valve and the 6th electrically-controlled valve to close, it is described Wind deflector is closed downwards, and second electrically-controlled valve and the 5th electrically-controlled valve are opened.
Correspondingly, in such a mode, first water pump needs to close, and the vent pads triple valve is also required to open left side Gas outlet, close right side gas outlet, i.e., opening catalyst converter to silencer direct channel so that engine exclude exhaust gas without The first plate heat exchanger is crossed, but is expelled directly out outside fuel vehicle.
In addition, in practical applications, during enforcement, the air-conditioner controller may also will not export the fuel vehicle The instruction of any one of the above operating mode.
Therefore in this case, first electrically-controlled valve to the 6th electrically-controlled valve is both needed to close, first water pump It needs to close, the vent pads triple valve needs unlatching left side gas outlet, closes right side gas outlet, i.e. opening catalyst converter is extremely eliminated the noise The direct channel of device, so that the exhaust gas that engine excludes but is expelled directly out outside fuel vehicle without the first plate heat exchanger.
It should be understood that being given above several operating modes, and the automotive thermal tube under relevant work mode The working condition of reason system is that the angle being in driving process from the fuel vehicle is illustrated.
But in practical applications, the fuel vehicle is when being in starting state, but not exercising state, in order to realize to combustion The interior automatic heating of oil (the present embodiment is mainly the heat of the exhaust gas excluded using engine to heat for fuel vehicle), equally It can first judge whether the coolant temperature of engine is greater than preset temperature threshold, if being not more than preset temperature threshold, The then circulation loop of the automotive thermal tube reason system work specifically: the compressor -> commutator -> third is board-like Heat exchanger -> the electric expansion valve -> second heat exchanger and second plate heat exchanger -> commutator -> described Gas-liquid separator -> the compressor.
However, it should be understood that in order to guarantee that above-mentioned circulation loop can work normally, in practical applications, specifically Need to be arranged first electrically-controlled valve, the 4th electrically-controlled valve and the 5th electrically-controlled valve are opened, second electrically-controlled valve, described Third electrically-controlled valve and the 6th electrically-controlled valve are closed.
By above-mentioned circulation loop, low-temp low-pressure gaseous coolant can be made to become high temperature and pressure gas after the compressor State carries out heat exchange with the engine low temperature coolant liquid in the 3rd plate heat exchanger after the commutator, makes coolant liquid It is heated, and then becomes cryogenic high pressure liquid, then after the electric expansion valve, refrigerant becomes low-temp low-pressure liquid, point It Jin Ru not second heat exchanger and second plate heat exchanger.Come at this point, the refrigerant in second heat exchanger can absorb From the heat that can absorb the exhaust gas excluded from engine in the refrigerant in the energy of outdoor air, second plate heat exchanger The energy of amount.After above-mentioned transformation, refrigerant will become low-temp low-pressure gaseous state at this time, finally by described in commutator arrival Gas-liquid separator returns to the compressor, completes circulation.
In addition, in such a mode, first water pump needs to open, the exhaust Electrocontrolled tee valve needs to open right side and goes out Port closes left side gas outlet, i.e. opening catalyst converter to the first plate heat exchanger, then to the channel of silencer, so that engine The exhaust gas of exclusion passes through the first plate heat exchanger, the load of acceleration motor in this way, so that the coolant liquid of engine It can be rapidly heated.
Correspondingly, after being heated by the coolant liquid that the circulation loop is the engine, if the engine Coolant temperature has reached preset temperature threshold, then closes above-mentioned circulation loop.Meanwhile first water pump is closed, control institute It states exhaust Electrocontrolled tee valve and opens left side gas outlet, close right side gas outlet, the i.e. direct channel of opening catalyst converter to silencer, So that the exhaust gas that engine excludes but is expelled directly out outside fuel vehicle without the first plate heat exchanger.
