Description
Technical field
The utility model relates to the field of refrigerating machine device, is specifically related to a kind of LNG vehicle-mounted cool-storage type chilled ceiling panel cold energy refrigerator.
Background technology
Clean as one, the efficient energy of natural gas, its utilization is significant to China's prevention and control of air pollution.In recent years, China's natural gas consumption figure increases fast, LNG (Liquefied Natural Gas) is as the liquid form of natural gas, natural gas through purified treatment, be cooled to below-162 DEG C time the liquid that formed, there is the flexibility adding natural gas accumulating and utilization in it, expands the range of application of natural gas.Nearly 2 years, LNG became the bright spot of Gas Industry development in the utilization of field of traffic.The efficient gas utilization project such as LNG automobile and marine fuel is clearly encouraged in country's natural gas development " 12 " planning, and gas-fueled vehicles are also classified as " first developing class " by October, 2012 new edition " gas utilization policy ".Under the support of national policy, bus, taxi " oil to gas " propose hard objectives are carried out in public transport field by multiple local government.LNG achieves fast development as vehicle fuel.
LNG advantages for development are in the automotive industry clearly: ignition point is low, combustion cleaning environmental protection, and without black smoke, without lime-ash and tar, almost can freely discharge, volume is little, and energy storage density is large, more than 2 times of continuous operating range normally CNG; Security performance is good, pressure store low (close to normal pressure), and density (0.45kg/m
3), than atmospheric density (0.55kg/m
3) low, leak in air and also to aerial diffusion, can not affect personal safety; Have good burning performance, anti-knock properties are strong.At present, China's LNG automobile industry is in the early stage of development, estimates that the quick growth of following China automobile pollution and the fast development of market for natural gas will drive the sustainable growth of LNG automobile industry, and LNG automobile developing prospect is bright.
LNG as vehicle fuel is the liquid form of natural gas, is stored in temperature more and is-162 DEG C, and pressure is in the low-temperature storage tank of about 0.1MPa.The favourable storage of LNG and transport, but the state gaseous state often when being finally utilized, therefore, LNG wanted first through overflash before being utilized.Facility and the power power consumption of producing 1 ton of liquefied natural gas are about 850kW.h, and in LNG receiving station, a large amount of cold of releasing during LNG vaporization, its value is about 830-860kJ/kg, and LNG vaporescence discharges with a large amount of cold energs.Reclaim this part cold energy, not only effectively make use of the energy, and decrease mechanically refrigerated a large amount of power consumption, there is considerable economic and social profit.And under normal circumstances, this part cold has been rejected usually in LNG vaporizer, cause the waste of mass energy, even also can cause environmental pollution.For this reason, LNG cold energy use causes the extensive concern of Chinese scholars.
At present, LNG cold energy use is generally divided into directly utilization and indirect utilization two kinds of modes.Wherein, direct utilization mainly concentrates on generating, air separation, manufacture dry ice, cold storage warehouse, desalinization, air conditioning for automobiles and the aspect such as cold temperature culture, cultivation.The mode of indirect utilization LNG cold energy mainly contains cryogenic pulverization, sewage disposal and desalinization etc.Indirect utilization mainly produces liquid nitrogen or liquid oxygen by LNG cold energy, and recycling liquid nitrogen, liquid oxygen carry out cryogenic pulverization, sewage disposal respectively.No matter being direct or the mode of indirect utilization LNG cold energy, is all recycled LNG cold energy by single channel, and from the angle analysis of thermodynamic analysis, single approach can not make full use of LNG cold energy, and loss is larger.Multiple way of recycling should fully utilize, to improve the utilization rate of LNG cold energy by a lot of expert's suggestion at present.Japan is one of country developing LNG cold energy use project the earliest, and in low-temperature electricity-generating, air liquefaction and frozen food etc., reach degree of being practical, economical, societal benefits are quite remarkable.However, current various countries LNG cold energy use rate is still not high, in areas such as Japan, Korea S and TaiWan, Chinas, only have the LNG cold of 20% to obtain utilization, and this technology of China is started late, and the example of application is little at present.
LNG cryogenic energy utilization is generally used for coach air conditioner and refrigerator car at automotive field, original mechanical refrigeration unit can be replaced like this, not only save investment, and eliminate electric energy and the noise pollution brought of compressor that mechanical refrigeration consumes, there is the double meaning of energy saving standard.But the application on heavy trucks the driver of LNG cold still belongs to blank.According to statistics, by the end of the year 2013, China LNG automobile pollution, more than 100,000, will be mainly bus and heavy truck.For heavy truck, driver hurries back and forth outside throughout the year, condition of work is arduous, diet is put up with, and usually wishes energy convenient diet in truck driver's long-distance transport, present circumstances, food is carried unrealistic with car, easily putrid and deteriorated, if car has the fresh-keeping foodstuff that can store 3-5 days magnitudes, will be a kind of behave be popular concerning truck driver.Meanwhile, heavily need to utilize extra heat in card power fuel LNG use procedure on the one hand LNG vaporization to safe combustion temperature, there is refrigeration demand again on the other hand, meanwhile, according to calculating, this cold can enough provide a small refrigerator to use.Therefore, the food storing refrigerator be equipped with in a long-distance transport way for heavy truck driver has significant realistic meaning and wide market prospects.
