Background technology
During navigation, diesel main engine is the capital equipment that ship consumes the energy to modern ships, and its power consumption occupies whole
The 70%-90% of the total power consumption of individual ship.But main frame thermal efficiency is low, less than 50%.Other heats are by aerofluxuss, cooling and radiating
It is emitted in air or marine environment etc. approach, not only waste the energy and also pollute environment.Discarded temperature is 260 DEG C～400 DEG C,
The outlet temperature of jacket-cooling water is at 70 DEG C～90 DEG C.
Ship air conditioning equipment, mainly based on steam compression type refrigeration, leans on refrigeration system evaporator pair to air-treatment at present
Air carries out dehumidification by condensation and cooling, and this desiccant cartridge cooling coupling air-treatment mode shortcoming is refrigeration system evaporating temperature mistake
Low, and it is understood that evaporating temperature lower refrigeration system efficiency is also lower, and used by ship, electric energy all is from diesel-driven generator
Group, therefore must bring and increase ship load added burden.The vapor compression refrigeration system cold-producing medium R22 containing chlorine element used
Ecological environment can be destroyed with substantial amounts of fuel oil carbon emission greenhouse gases.
Due to the drastically decline of China coastal seas fishery resources and the official signature with surrounding countries fisheries agreements and implement,
The working space of China's sea fishery more come with little, China's fishery economic except development seawater fishery outer it is necessary to participate in developing
Long range fishing, tuna is the first-selected fingerling of development long range fishing, but the special trait of tuna requires tuna storage, adds
Work must assure that -50 DEG C to -60 DEG C of low temperature environment.And condensation temperature is at 40 DEG C, for this now golden rifle fishing boat equipped with list
Machine double-stage compressor.Distant water Tuna Fisheries operation ship deepfreeze, Freezing System typically adopt piston type list at present

The using method of the present invention：The marine vehicle cool house system of this absorption waste heat auxiliary cooling has three kinds of methods of operation, the
One kind is conventional operation, only runs compression refrigeration circuits, and compression refrigeration circuits carry out supercool running；I.e. absorption ammonia refrigeration system
System is in off position, and the two-stage compression refrigeration state that only low pressure compressor 1 is worked with high pressure compressor 2, is high/low temperature
Freezer provides cold.At this moment electromagnetic valve 4 is channel status, and cold-producing medium is pressed into fluorine condenser 3 by high pressure compressor 2, thus freezes
Agent is changed into saturation liquid, and subsequent cold-producing medium is divided into two before intercooler 6, the heat exchange disk of an inflow intercooler 6
Guan Zhong, another, through electromagnetic valve 4 and the first expansion valve 5, evaporates, thus exchanging the system in hot coil in intercooler 6
Cryogen carries out saturation makes it supercool, supercool after cold-producing medium branch pass through the 3rd expansion valve 7, the 4th expansion valve 9, and then bifurcate
Flow into high-temperature refrigeration device 10, cryogenic refrigerator 8, to realize the refrigerating operation of high and low temperature freezer.
In the first method of operation, flow through low pressure compressor 1, the refrigerant flow of high pressure compressor 2 is different, stream
Cross the flow of high pressure compressor 2 low pressure compressor 1 to be more than, and be really used for the stream only flowing through low pressure compressor 1 of refrigeration
Amount, the additional flow of high pressure compressor 2 is used for cooling down another branched-refrigerant in Liang Ge branch in intercooler 6,
Make it supercool.Thus on the one hand increase the refrigerating capacity of unit mass in refrigerator, be on the other hand used for cooling down low pressure compressor 1
Aerofluxuss, reduce the energy consumption of high pressure compressor 2.
Second is all run with sweat cooling loop for compression refrigeration circuits, but compression refrigeration circuits do not carry out supercool fortune
Make.Absorption ammonia refrigeration system and conventional two-stage compression system are all devoted oneself to work state, but at this moment electromagnetic valve 4 is in cut out shape
State.Rely on the water in diesel engine 12 and host cylinder cooling water and exhaust heat heating water tank 13 so as to be warming up to 80 DEG C～90
℃.Hot water heats dilute ammonia-water solution so that ammonia evaporates from aqueous solution in steam generator 14, then through rectifier 15
Ammonia is separated from water vapour, then is cooled to liquefied ammonia through ammonia condenser 16, be then passed through the second expansion valve 17 throttling action,
Evaporate in intercooler 6, for the cold-producing medium in saturation heat exchange coil so as to the big temperature difference supercool to increase semen donors, supercool
Cold-producing medium branch afterwards passes through the 3rd expansion valve 7, the 4th expansion valve 9, and then bifurcates inflow high-temperature refrigeration device 10, cryogenic refrigeration
Device 8, to realize the refrigerating operation of high and low temperature freezer.Again by water in another aspect ammonia inflow absorber 18 after evaporation gasification
Absorb, and its heat of solution taken away by sea water, ammonia-water solution by solution pump 19 blowback steam generator 14, therebetween through solution heat
Exchanger 20, by the hot water heating from steam generator 14.
During the second method of operation, the refrigerant quality that low pressure compressor 1 is flow through with high pressure compressor 2 is identical.With
Ammonia absorption refrigeration produces cold and replaces conventional operation mode, expands method for evaporation refrigerating by shunting in intercooler 6, from bavin
For oil machine 21 groups of waste heats of 12 electromotor, it is fully able to meet, thus can make the cold-producing medium degree of supercooling of refrigerator in freezer more
Greatly, thus improve the refrigerating capacity of cold-producing medium unit mass, same refrigerator can improve evaporating temperature, further improve refrigeration
The coefficient of performance is it is also possible to reduce compressor capacity.
The third is all run with sweat cooling loop for compression refrigeration circuits, and compression refrigeration circuits carry out supercool running.
I.e. absorption ammonia refrigeration system and conventional two-stage compression system are all devoted oneself to work state, and at this moment electromagnetic valve 4 is opening state.In conjunction with
First two operation, and cold produced by absorption ammonia refrigeration system is for making the cold-producing medium of entrance refrigerator be in depth
Supercooled state, to improve refrigeration system efficiency.
During the third method of operation, it is mainly used in, when absorption pattern generation cold is inadequate, supplementing a part from condenser
Cold-producing medium evaporation cooling out increased cold, for improving cycle efficieny.
