Below by specific embodiment to the present inventionLNG air-conditioning refrigeration system of vehicleIt is described in further detail.
Such as Fig. 1Shown in,LNG air-conditioning refrigeration system of vehicle, including LNG steel cylinder 1, temperature control equipment 2, A/C evaporator 3 and electromotor 4, connected by the first pipeline 5 between LNG steel cylinder 1 and temperature control equipment 2, connected by the second pipeline 6 between temperature control equipment 2 and A/C evaporator 3, described temperature control equipment 2 includes intensification blower fan and intensification coil pipe, the two ends of intensification coil pipe respectively with the first pipeline 5, second pipeline 6 connects, the present embodiment utilizes intensification blower fan heating cryogenic liquid, certainly it is heated also may be used to it with hot power and water, it is in summer owing to being typically all when opening air-conditioning, therefore ambient temperature far above required by A/C evaporator 3 DEG C, so intensification blower fan has good heats to cryogenic liquid blowing, thus reaching to control the purpose of cryogenic liquid temperature.nullConnected by the 3rd pipeline 7 between A/C evaporator 3 and electromotor 4，First pipeline 5 is provided with electromagnetic valve 9，Second pipeline 6 is sequentially installed with fluid reservoir 10 and flow control valve 11 along the flow direction of LNG，3rd pipeline 7 is provided with manostat 18 and corresponding check valve 16，Intensification coil outlet is provided with outlet temperature sensor 12，Vehicle interior temperature sensor 14 is installed in car，A/C evaporator 3 exit is also equipped with evaporator outlet temperature sensor 13，Described outlet temperature sensor 12、Evaporator outlet temperature sensor 13、Vehicle interior temperature sensor 14、Electromagnetic valve 9、Flow control valve 11 controls by electric control gear 15，The 4th pipeline 8 it is also associated with between LNG steel cylinder 1 and manostat 18，4th pipeline 8 is provided with carburator 17 and corresponding check valve 16，Carburator 17 is heated by engine thermal water pipe 19.
Described air-conditioning refrigeration system also includes device for quickly elevating temperature 20, this device for quickly elevating temperature 20 connects with the first pipeline 5 and the second pipeline 6 respectively, device for quickly elevating temperature 20 includes boiler and the heat exchanger coil being arranged in boiler, the water inlet of this boiler connects with the hot-water line of electromotor 4, heat exchanger coil two ends connect with the first pipeline 5 and the second pipeline 6 respectively, described device for quickly elevating temperature 20 has corresponding Valve controllingIn figureValve omits and is not drawn into.From function this, device for quickly elevating temperature 20 and temperature control equipment 2 can use parallel or be used alone, only the programming rate of device for quickly elevating temperature 20 is quicker, therefore, device for quickly elevating temperature 20 is usually the first few minutes work opened at air-conditioning, the LNG that LNG steel cylinder 1 flows out is brought rapidly up DEG C, thus can A/C evaporator just can rapid operation, thus avoiding the embarrassment that after air-conditioning is opened, the long period does not also freeze.And device for quickly elevating temperature 20 also not necessarily to utilize automobile engine hot water to heat up, it is also possible to there are other modes, such as electrical heating or electricity, comprehensive hot water use.
LNG air-conditioning refrigeration system of vehiclenullFlow process as follows: when the air conditioning is turned on，Controlled electromagnetic valve 9 by electric control gear 15 to open，Cryogenic liquid enters into device for quickly elevating temperature 20 in advance and is rapidly heated to meet the use of A/C evaporator 3，Certainly，Cryogenic liquid is also into the intensification coil pipe of temperature control equipment 2，Intensification coil pipe is heated heating up by intensification blower fan，The outlet temperature sensor 12 of intensification coil outlet controls outlet temperature，Guarantee outlet temperature DEG C between time，So can by temperature control equipment 2 main thermogenic action，Now，Temperature DEG C between gas-liquid mixture enter back into fluid reservoir 10 to guarantee the normal feed flow of A/C evaporator 3，Enter back into flow control valve 11，The control of flow control valve 11 flow constantly adjusts with A/C evaporator 3 inlet temperature: evaporator outlet temperature sensor 13 temperature reaches 10 DEG C，Flow control valve 11 enlargement discharge，Make more liquid enter A/C evaporator 3 and absorb heat，When reaching DEG C such as A/C evaporator 3 evaporator outlet temperature sensor 13，Flow turned down by flow control valve 11，Reduce liquid and enter A/C evaporator 3，The gas temperature flowing out A/C evaporator 3 is higher，Manostat 18 is arrived through check valve 16，Carry out pressure adjustment，Finally enter electromotor 4 to burn；When the signal that vehicle interior temperature sensor 14 accepts reaches air-conditioning design temperature, controlling device and control to automatically cut off the power supply of electromagnetic valve 9 and temperature control equipment, air conditioning system is still normally blown.
Additionally, if the liquid of temperature control equipment 2 outlet can not meet the requirement of A/C evaporator 3, device for quickly elevating temperature 20 can also be opened, utilize the heat of engine thermal water pipe 19 that cryogenic liquid is heated, liquid is delivered to after reaching requirement fluid reservoir 10 again.
When A/C evaporator 3 does not work or when the natural gas of A/C evaporator 3 outlet output is not enough to provide the fuel needed for electromotor 4, check valve 16 on 4th pipeline 8 is opened, low temperature LNG liquid enters carburator 17 from LNG steel cylinder, heating gasified at engine thermal water pipe 19, natural gas after gasification enters in manostat 18, enters into burning in electromotor 4 after being adjusted to suitable pressure.
The alternative compressor cooling of above-mentioned air-conditioning refrigeration system, greatly reduce cost, and utilize LNG to enter directly in A/C evaporator 3, in whole process of refrigerastion, also it is the temperature-rise period to LNG, and this temperature-rise period is by chance the process of LNG supply engine burning, therefore, this refrigeration system makes energy reach the use of optimum, serves the effect of energy-conserving and environment-protective.
