Embodiment
LNG air-conditioning refrigeration system of vehicle of the present invention is described in further detail below by specific embodiment.
As shown in figure 1, LNG air-conditioning refrigeration system of vehicle, including LNG steel cylinders 1, temperature control equipment 2, A/C evaporator 3
And engine 4, connected between LNG steel cylinders 1 and temperature control equipment 2 by the first pipeline 5, temperature control equipment 2 and air-conditioning
Connected between evaporator 3 by the second pipeline 6, the temperature control equipment 2 includes heating blower fan and heating coil pipe, and heat up disk
The both ends of pipe are connected with the first pipeline 5, the second pipeline 6 respectively, and cryogenic liquid is heated using the blower fan that heats up in the present embodiment, when
So with hot water and electricity it is heated also can, due to being typically in summer when opening air-conditioning, therefore ambient temperature is remote
Higher than -3 ~ 5 DEG C required by A/C evaporator 3, so heating blower fan has good heating effect to cryogenic liquid blowing, from
And reach the purpose of control cryogenic liquid temperature.Connected between A/C evaporator 3 and engine 4 by the 3rd pipeline 7, first
Magnetic valve 9 is installed on pipeline 5, fluid reservoir 10 and flow control valve 11 are sequentially installed with along LNG flow direction on the second pipeline 6,
3rd pipeline 7 is provided with voltage-stablizer 18 and corresponding check valve 16, and heating coil outlet is provided with outlet temperature sensor
12, in-car is provided with vehicle interior temperature sensor 14, and the exit of A/C evaporator 3 is also equipped with evaporator outlet temperature sensor
13, the outlet temperature sensor 12, evaporator outlet temperature sensor 13, vehicle interior temperature sensor 14, magnetic valve 9, flow
Regulating valve 11 is controlled by electric control gear 15, and the 4th pipeline 8, the 4th pipeline are also associated between LNG steel cylinders 1 and voltage-stablizer 18
Vaporizer 17 is installed on 8 and corresponding check valve 16, vaporizer 17 are heated by engine thermal water pipe 19.
The air-conditioning refrigeration system also includes device for quickly elevating temperature 20, the device for quickly elevating temperature 20 respectively with the first pipeline 5
Connected with the second pipeline 6, device for quickly elevating temperature 20 includes boiler and the heat exchanger coil being arranged in boiler, the hot water
The water inlet of case connects with the hot-water line of engine 4, and heat exchanger coil both ends connect with the first pipeline 5 and the second pipeline 6 respectively
Logical, the device for quickly elevating temperature 20 has a corresponding Valve controlling, and valve, which omits, in figure is not drawn into.From function this, it is quick to rise
Warm device 20 and temperature control equipment 2 can be used or are used alone parallel, only the programming rate of device for quickly elevating temperature 20
More quick, therefore, device for quickly elevating temperature 20 is usually the first few minutes work opened in air-conditioning, and LNG steel cylinders 1 are flowed out
LNG is brought rapidly up -3 ~ 5 DEG C, thus can A/C evaporator just can rapid operation, so as to avoid air-conditioning open after it is longer
The embarrassment that time does not freeze also.And device for quickly elevating temperature 20 also will not necessarily be heated up using automobile engine hot water, also
There can be other modes, as electrical heating or electricity, comprehensive hot water use.
The flow of LNG air-conditioning refrigeration system of vehicle is as follows：When the air conditioning is turned on, magnetic valve 9 is controlled to open by electric control gear 15
Open, cryogenic liquid enters device for quickly elevating temperature 20 and is rapidly heated to meet the use of A/C evaporator 3, certainly, low temperature in advance
Liquid also enters the heating coil pipe of temperature control equipment 2, and heating blower fan carries out heat temperature raising to heating coil pipe, and heating coil pipe goes out
Outlet temperature sensor 12 at mouthful controls outlet temperature, it is ensured that outlet temperature, so can be by temperature control when between -3 ~ 5 DEG C
Device 2 processed plays main thermogenic action, and now, gas-liquid mixture of the temperature between -3 ~ 5 DEG C enters back into fluid reservoir 10 to ensure
The normal feed flow of A/C evaporator 3, flow control valve 11 is entered back into, the control of the flow of flow control valve 11 is with A/C evaporator
3 inlet temperatures constantly adjust：The temperature of evaporator outlet temperature sensor 13 reaches 10 DEG C, the enlargement discharge of flow control valve 11, makes
More liquid enter A/C evaporator 3 and absorb heat, as the evaporator outlet temperature sensor 13 of A/C evaporator 3 reaches -3
DEG C when, flow control valve 11 turns flow down, reduces liquid and enters A/C evaporator 3, the gas temperature of outflow A/C evaporator 3
It is higher, voltage-stablizer 18 is reached by check valve 16, pressure regulation is carried out, finally enters engine 4 and burn；When vehicle interior temperature passes
When the signal that sensor 14 receives reaches air-conditioning design temperature, control device control automatically cuts off magnetic valve 9 and temperature control equipment
Power supply, air-conditioning system still normally blows.
In addition, if when the liquid that temperature control equipment 2 exports can not meet the requirement of A/C evaporator 3, can also open
Device for quickly elevating temperature 20 is opened, cryogenic liquid is heated using the heat of engine thermal water pipe 19, is reached after requirement again by liquid
Body is delivered to fluid reservoir 10.
When A/C evaporator 3 does not work or when the natural gas of the outlet of A/C evaporator 3 output is not enough to provide engine
During fuel needed for 4, the check valve 16 on the 4th pipeline 8 is opened, and low temperature LNG liquid enters vaporizer 17 from LNG steel cylinders,
Gasify under the heating of engine thermal water pipe 19, the natural gas after gasification is entered in voltage-stablizer 18, after suitable pressure is arrived in regulation
Enter in engine 4 and burn.
The alternative compressor cooling of above-mentioned air-conditioning refrigeration system, cost is greatly reduced, and it is direct using LNG
Enter in A/C evaporator 3, in whole process of refrigerastion, and the temperature-rise period to LNG, and this temperature-rise period is by chance
It is the process of LNG supply engines burning, therefore, the refrigeration system makes energy reach optimal use, serves energy-saving ring
The effect of guarantor.
