Description
Technical field
The invention belongs to automobile adjustment technical field, relate to a kind of temperature control equipment and method that is used for automobile, be specifically related to a kind of LNG cold energy device and method that is used for the truck air conditioning system.
Background technology
Along with the raising day by day of Chinese national economy level and the develop rapidly of auto-industry, when automobile pollution sharply increased in recent years, people were also increasingly high to the requirement of car comfort.Air conditioning for automobiles not only is able to widespread use as an important symbol of car comfort on car and passenger vehicle, and fields such as own entering lorry, engineering truck, van cooler and trac., and the entrucking rate is in rapid rising.
Automotive air-conditioning system is made up of refrigeration system, heating system, supply air system and control system four parts.Its working process is: compressor at first is compressed to high-temperature high-pressure state with low-temp low-pressure gaseous state refrigerated medium; Circulating water heat exchange at condenser place and cooled engine becomes the high-temperature liquid state refrigerant then, becomes low pressure atomized through expansion valve behind the dry filter, in evaporator, absorbs heat at last and becomes gaseous state; The evaporator surface temperature descends thereupon; Through blowing engine cold wind is delivered in the compartment, gaseous refrigerant is compressed machine again and sucks, repeatedly circulation.Big, the Heavy Weight of these major part volumes of compressor, condenser, evaporator, air-supply arrangement and pipeline has wherein increased the weight of car load; Again since the power resources of compressor in automotive engine; Not only increased consumption of fuel; And strengthened discharge amount of exhaust gas, and cause that water tank is overheated, influence the tractive performance of vehicle; And cause refrigeration compressor used for automobile air conditioning can only adopt the structural shape of open-type, thereby brought the axle envelope to require problem high, that refrigerant leaks easily; And when automobile goes, is in idling mode at a slow speed or stops, because compressor leans on engine drive, thus be difficult to keep stable air conditioning condition, even can't normal operation.
Air conditioning for automobiles; Especially the running environment of the A/C of truck, engineering truck is abominable, and not only the environmental parameters fluctuation is big, and often follows concuss; And H Exch is prone to problems such as ash blocks up; Therefore, compare with the building air conditioning device, truck, engineering truck A/C often exist shortcomings such as efficient is low, service life short, maintenance workload is big, the working medium leakage is serious.At present, manned vehicles such as car, passenger vehicle have all been equipped A/C basically, and special vehicle popularity rates such as truck, special vehicle are very low.At present, China widely used with low and middle-grade time be that master's lorry, the conditioning unit equipment rate of special vehicle are merely about 5%, wherein quite a few still is that automobile dispatches from the factory and adds up afterwards, well below the air conditioning device rate of manned vehicles such as car, passenger vehicle.
(be called for short: main component LNG) is a methane to liquefied natural gas, and its colourless, tasteless, nontoxic and non-corrosiveness has characteristics such as calorific value is big, performance is high, pollute less, accumulating is convenient, is a kind of cleaning, efficient, convenient, the safe energy.LNG is used for automobile industry, and the maximum characteristics of this class natural gas automobile are " cleanings ", and especially the LNG heavy duty truck is considered to real zero emission vehicle.
The temperature of LNG is-162 ℃, and will in driving engine, use natural fuels, and its temperature is necessary for 20～50 ℃, if natural fuels and air are directly carried out the exchange of latent heat, sensible heat, heat transfer temperature difference will reach 182～210 ℃.So big heat transfer temperature difference is difficult to realize to air heat exchanger.
