Five, the specific embodiment
In order more to be expressly understood the present invention, the present invention is described in further detail below in conjunction with accompanying drawing and principle.
Referring to Fig. 1, Fig. 1 is a principle schematic of the present invention; According to technical scheme of the present invention, utilize the motorcar air conditioner of cold energy of liquefied natural gas to comprise: liquefied natural gas cylinder 1, coil heat exchanger 2, double-tube heat exchanger 3, plate-fin heat exchanger 4, ethylene glycol cold-accumulating box 5, air cooling heat exchanger 6, liquid pump 7, filter 8 and relevant condenser 9,1 of automobile engine 0, coolant storage tank 11, Subzero valve 12, low pressure gasholder 13;
Coil heat exchanger 2 is arranged in the liquefied natural gas cylinder 1, and is communicated with double-tube heat exchanger 3 and plate-fin heat exchanger 4; Plate-fin heat exchanger 4 also is connected with ethylene glycol cold-accumulating box 5, liquid pump 7 respectively; Ethylene glycol cold-accumulating box 5 is communicated with air cooling heat exchanger 6 and is connected plate-fin heat exchanger 4 through liquid pump 7; Plate-fin heat exchanger 4 also is communicated with 1 of automobile engine 0 by condenser 9, low pressure gasholder 13;
The heat that 1 of automobile engine 0 produces cools off by cooling water expansion tank, to be cooling water expansion tank enter condenser 9 through coolant storage tank 11 carries out heat exchange with natural fuels, enters behind the drop in temperature in the 1 of automobile engine 0, and driving engine is cooled off, return coolant storage tank 11, so repeatedly circulation.
Liquefied natural gas cylinder 1 is the low temperature fluid reservoir of multi-layer vacuum shielding.
Plate-fin heat exchanger 4 is five plumes, nine channel heat exchangers.
Coil heat exchanger 2 is three coil heat exchangers that copper pipe turns to.
Principle of work of the present invention is that the coil heat exchanger of three copper pipe coilings of dress is connected for filled jar with LNG by cryogenic valve in the LNG Dewar.Plate-fin heat exchanger is five plumes, nine channel heat exchangers, wherein walks natural fuels (four passages) for four strands, and one walks ethylene glycol solution (five passages), and natural fuels and ethylene glycol passage are alternately.During automobile starting, LNG Dewar valve open, the saturated gaseous natural gas on Dewar top enters in the low temperature double-tube heat exchanger under the system pressure effect, the natural fuels higher with the temperature of adverse current carries out interchange of heat, the release portion cold, temperature build-up enters in the plate-fin heat exchanger then, carry out interchange of heat once more with the ethylene glycol solution of adverse current, temperature further rises to more than 0 ℃.The higher natural fuels of the temperature of coming out from plate-fin heat exchanger returns the LNG Dewar, carries out interchange of heat with the outer LNG of pipe in the low-temperature coil heat exchanger, and LNG is gasified, while self drop in temperature, become cryogenic gas, enter heat exchange in the plate-fin heat exchanger again, so carry out twice circulation.In circulation for the third time, natural fuels enters the low temperature double-tube heat exchanger after plate-fin heat exchanger comes out, be used for heating low temperature saturated natural gas from cooled cryostat, then get back to the LNG Dewar, further cooling in the low-temperature coil heat exchanger, enter once more in the plate-fin heat exchanger, carry out interchange of heat with the ethylene glycol solution of shunting.Like this, the low temperature saturated natural gas of coming out from the LNG Dewar by low pressure gasholder, enters the engine cold condenser again through repeatedly lowering the temperature and heating up, and through the further heating of cooling water expansion tank, then sends into the combustion chamber of driving engine.
Carry cold after ethylene glycol solution is cooled and enter cold-storage groove in plate-fin heat exchanger, the ethylene glycol solution that these temperature are lower enters in the air heat exchanger through the pump pressurization, cooling is from the return air in compartment, ethylene glycol solution behind the temperature build-up enters plate-fin heat exchanger once more through filter, carries out interchange of heat with cryogenic natural gas and obtains cold.In air heat exchanger by the return air after the cooling with send the compartment back to after newly wind mixes in proportion, reach the effect of air-conditioning.
In the car running process, according to the flow of air heat exchanger leaving air temp automatically regulating ethylene glycol, to satisfy the cooling load under the different rows turner condition.After avoiding long-time the parking, the air in a car compartment cooling rate is too slow, and the low temperature ethylene glycol solution that comes out from plate-fin heat exchanger can be without cold-storage groove and directly through being pumped into air heat exchanger.When system's cooling surpasses cooling load and requires, again the low temperature ethylene glycol solution is sent into cold-storage groove surplus will have been crossed storage, the air-conditioning cooling load when stopping to satisfy auto idle speed.
Characteristics of the present invention are:
(1) adopt secondary refrigerant indirect heat exchange mode, solved LNG direct quenching ambient air and frosting appears, heat exchanger stops up and the low excessively situation such as health that is unfavorable for of cold air temperature.
The selection of secondary refrigerant: ethylene glycol is a kind of non-toxic, environmental friendly secondary refrigerant, the solidfying point of ethylene glycol solution low (the glycol water solidfying point of variable concentrations is difference to some extent), and specific heat capacity is big, and human body is not had harm.Therefore, can select suitable solution concentration according to the design-calculated needs.Bigger specific heat capacity is for realizing that high efficient heat exchanging and storing of energy have important effect.
Determining of refrigerant state parameter: air-conditioning is about 5 ℃ to the suitable wind pushing temperature of human body, considers the solidfying point parameter of the heat transfer temperature difference and the ethylene glycol of forced air cooler, and the minimum temperature of getting ethylene glycol is between-10 ℃～-5 ℃.
(2) adopt repeatedly the cold extraction method that the gasification latent heat of LNG is converted into gas sensible heat, avoided the frozen problem of secondary refrigerant
Repeatedly the advantage of cold extraction method is: the gasification of LNG is finished in the LNG Dewar fully, promptly phase-change heat-exchanger is placed in the cooled cryostat, what come out from Dewar then is gaseous natural gas fully.Gaseous natural gas can be controlled at higher temperature, avoids freezing ethylene glycol solution in main heat exchanger, causes constricted flow.
(3) adopting based on low temperature multiple flow plate type finned heat exchanger, coil tube type and double pipe heat exchanger is the composite heat-exchange system of assisting, and has solved the uneven problem of heat transfer temperature difference.
The effect of low temperature multiple flow plate type finned heat exchanger is that the cold of LNG is passed to the secondary refrigerant ethylene glycol by gaseous natural gas, realizes the purpose of air-conditioning by the glycol-cooled air.The plate type finned heat exchanger specific floor area is big, volume is little, high-efficiency compact, and a plurality of fluids heat exchange simultaneously, and the heat transfer temperature difference of each passage fluid reaches and optimizes the effect of conducting heat by reasonably design.Realized the fluid heat exchange of five-way road here, heat exchange between four strands of natural fuelses and one ethylene glycol solution.
Tube exchanger is a phase-change heat-exchanger, reaches the purpose of gasification by the natural gas in gaseous state heating liquid.Tube exchanger is placed in the LNG Dewar, does not increase additional space, does not also observe from the outside.Here three mini disk tubular heat exchangers have been arranged.
Double pipe heat exchanger here mainly effect be by the high-temperature gas heating that refluxes LNG saturated vapor from Dewar, promote the inlet temperature that enters the main heat exchanger cold air, avoid freezing of ethylene glycol.Double pipe heat exchanger is very compact, does not occupy additional space, and also has the effect of cold insulation.
(3) utilize secondary refrigerant as agent for storage of coldness, its reserves of rational Match and flow, the adjusting and the deposit of realization cold are to satisfy the demand of cold under the different rows turner condition.
In general, it is many more that driving engine consumes gas fuel, and the cold that LNG provided is also big more.And under different seasons and the different driving operating mode, the demand to air-conditioning cold flow in the car hold does not change because of consume fuel is different.The raising of cold and demand are not necessarily in full accord, may produce contradiction sometimes.The thought of cold-storage is exactly a kind of means that solve the cold imbalance between supply and demand, and cold accumulation system is temporarily laid in the cold of surplus, discharges when the big cold of needs.The invention provides one is the cold-accumulating box of agent for storage of coldness with the ethylene glycol, realizes cold-storage by specific heat capacity and a certain amount of ethylene glycol solution that ethylene glycol is big.The selection of ethylene glycol solution amount has influence on the cold-storage ability, also has influence on the refrigeration cool-down speed when starting.Solution amount is big more, and the cold-storage ability is strong more, and it is slow more to start cooling rate.The present invention adopts the flow bypass under the automatic guidance to coordinate this contradiction.
Adopting the present invention is the miniature car of 1.8L for free air capacity, presses the consumption of the LNG of 20L/100km (about 30L/h) and calculates, and LNG can provide cold 3kW.Consider that the cold loss caused by heat inleak and the re-heat of system not exclusively lose, the cold of recovery can be used for the air-conditioning of miniature car.
Referring to Fig. 2,3; Fig. 2, the 3rd, experimental system scheme drawing of the present invention and photo; 25-30 ℃ of measuring ambient temperature, open the low temperature aie escape valve of LNG tank top after, the temperature that the each point temperature reaches refrigerant ethylene glycol in the chilling air conditioning system over time in the low-temperature heat exchange system in 30 minutes is tested over time; Simultaneously, air heat exchanger cold wind temperature out, the back refrigerant that stops in 5 minutes are also tested over time with air heat exchanger cold wind temperature out, with simulated automotive start, mapping during parking.In addition, outlet of air heat exchanger cold wind and agent for storage of coldness ethylene glycol turnover plate-fin heat exchanger temperature are tested over time during also to systematic steady state, and also under the varying environment temperature, the cold of system recoveries is tested simultaneously.Laboratory test results shows that cold energy of liquefied natural gas reclaims automotive air-conditioning system and has mapping and steady-state behaviour preferably.Under the transient condition, the air heat exchanger leaving air temp just can reach the wind pushing temperature (below 15 ℃) of air-conditioning in a few minutes.During steady state condition, the percent recovery of total system cold remains on more than 80%, and actual cold recovery can satisfy the cooling load demand of miniature car about 2.5kW.It is stable that the cold-storage effect also keeps, and when the LNG stop supplies, cold accumulation system continued cooling after 10 minutes, and the agent for storage of coldness temperature only raises about 2 ℃.Therefore, the LNG motorcar air conditioner has good cold balancing and regulatory function.
