Technical field
The present invention relates to the refrigeration technology of automobile, relate in particular to a kind of environment protection type refrigerated truck.
Background technology
At present, it is several that refrigerator truck mainly contains mechanical type refrigerator truck, liquid nitrogen storage automobile, cold drawing formula refrigerator truck, dry ice refrigerator truck and (salt) ice-cold Tibetan automobile etc., wherein mechanically refrigerated lorry is equipped with the mechanical refrigeration device specially cold is provided, and is most widely used.But the refrigerator truck of this employing compression refrigeration unit, compressor is generally all driven by drive coupling by automotive engine, and it is very big that refrigerating capacity is influenced by the speed of a motor vehicle; In addition, because the vibrations of unit very easily damage refrigeration system, cause leakage of refrigerant, contaminated environment.And, above-mentioned refrigerator truck or need drive fridge equipment work, consumes energy by automobile; Need the special refrigerant of periodic replacement, increase cost.
Summary of the invention
The objective of the invention is to, a kind of environment protection type refrigerated truck is provided, it can utilize liquefied natural gas (Liquefied Natural Gas is called for short LNG) to freeze, and will fully discharge the fuel of the natural fuels of cold as automobile then.
In order to achieve the above object, the present invention adopts following technical scheme to be achieved:
A kind of environment protection type refrigerated truck comprises the fridge equipment that is arranged in the compartment, it is characterized in that, the fuel of refrigerator truck and the refrigerant of fridge equipment are liquefied natural gas, and the refrigerant pipe of fridge equipment is serially connected in the fuel canal front end of refrigerator truck.
The further improvement of the present invention scheme is as follows:
(1) described fridge equipment comprises LNG carburetter with multiple flow gangway and a plurality of phase change cold-storages unit that is arranged on the compartment roof, and described a plurality of phase change cold-storages unit is serially connected in the fuel canal front end of refrigerator truck by the LNG carburetter.
Described phase change cold-storage unit is the casing type heat exchanging structure, is filled with solid-liquid phase change working medium in the intermediate annular space.
(2) described fridge equipment comprises coil heat exchanger and the blower fan that is provided with near car body top, and described coil heat exchanger is serially connected in the fuel canal front end of refrigerator truck, and described blower fan carries out air-cooled to coil heat exchanger.
Because refrigerator truck of the present invention is with liquefied natural gas (Liquefied Natural Gas, be called for short LNG) as fuel, LNG is the low-temperature mixed thing after the natural gas liquefaction, the normal pressure saturation temperature is 111K, volume is about 1/625 of gaseous state volume, and LNG needs gasification heating before use, supplies with automotive engine after making it to be warming up to normal temperature, discharge a large amount of cold energy in its gasification, reclaiming this part cold is that refrigerator carriage is used.Simultaneously, adopting the refrigerator truck of LNG is a kind of environment protection type refrigerated truck of real green cleaning.Natural fuels at first will carry out purification process in liquefaction process, not sulfur-bearing and nitrogen among the LNG, and its main component is CH
4, stay in grade, it is easy to adjust to burn, no black smoke, burning no lime-ash in back and tar, main blowdown is H
2O and CO
2, can be rated as green fuel.In addition, adopt the refrigeration system of the refrigerator truck of LNG not use refrigerant, so there is not the problem of environmental pollution that brings owing to leakage of refrigerant, its refrigerating capacity from the LNG gasification cold that rewarming provided, does not need other consumes energy fully.Therefore, refrigerator truck of the present invention not only has high energy utilization rate, and green non-pollution, has a extensive future.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the cold storage environment protection type refrigerated truck structural front view that the present invention utilizes the phase change cold-storage technology;
Fig. 2 is the cold storage environment protection type refrigerated truck birds-eye view that the present invention utilizes the phase change cold-storage technology;
Fig. 3 is the direct-cooling type environment protection type refrigerated truck structural representation that the present invention directly utilizes the LNG cold.
The specific embodiment
With reference to Fig. 1, Fig. 2, one embodiment of the present of invention are to utilize a kind of cold storage environmental protection refrigerator truck of phase change cold-storage technical design, and it comprises: LNG storage tank 1, clack box 2, LNG carburetter 3, the first phase change cold-storage unit 4, the second phase change cold-storage unit 5, third phase become cold-storage unit 6, gas heater 7, automotive engine 8 and connecting tube etc.The phase change cold-storage unit is the casing type heat exchanging structure, is filled with solid-liquid phase change working medium in the intermediate annular space, as glycol water or ammonia chloride water solution etc.
The connection mode of above-mentioned parts is in proper order: the outlet of LNG storage tank 1, through pipeline C1, clack box 2, pipeline C2, first inlet that connects LNG carburetter 3 with multiple flow heat exchange function, first outlet of LNG carburetter 3 is connected with the inlet of the first phase change cold-storage unit 4 that is installed in refrigerator truck railway carriage or compartment inner roof wall by pipeline C3, and the outlet of the first phase change cold-storage unit 4 links to each other with second inlet of LNG carburetter 3 by pipeline C4 again; Second outlet of LNG carburetter 3 is connected with the inlet of the second phase change cold-storage unit 5 that is installed in refrigerator truck railway carriage or compartment inner roof wall by pipeline C5, and the outlet of the second phase change cold-storage unit 5 is connected with the 3rd inlet of carburetter 3 by pipeline C6; The 3rd outlet of carburetter 3 links to each other with the inlet that the third phase that is installed in the refrigerator carriage inner roof wall becomes cold-storage unit 6 by pipeline C7, and the outlet of third phase change cold-storage unit 6 is crossed clack box 2 through pipeline C8 and linked to each other with gas heater 7 cold fluids inlet.The outlet of gas heater 7 links to each other with driving engine (8) induction tract.
Liquefied natural gas from LNG storage tank 1 by clack box 2 dominant discharge after, in LNG carburetter 3, become cryogenic natural gas by backflow natural fuels heating and gasifying rewarming, enter the first phase change cold-storage unit, 4 released cold quantities that place top in the compartment again, enter 3 coolings of LNG carburetter after the intensification again, gasification simultaneously is the rewarming LNG next by LNG storage tank 1 also, enter then in the second phase change cold-storage unit 5 behind the released cold quantity, be back to cooling in the LNG carburetter 3 once more, after entering cold-storage unit 6 intensification released cold quantities at last, flow into natural gas flow control valve case 2, after gas heater 7 heating, enter driving engine 8 work by combustion.Air is cooled off by three cold-storage unit in the refrigerator truck railway carriage or compartment, forms the free convection circulation at box house.
