Description
Technical field
A kind of hot water type lithium bromide absorption cooling water dispenser group that solution series occur with single-action of the present invention, belongs to air-conditioning equipment skill
Art field.
Background technology
, it is necessary to be freezed or heated using air-conditioning in production technology or life, and these need to consume certain energy
It could realize.Exist largely in production technology simultaneously again in（It is low）Warm used heat, some used heat are arranged due to that can not utilize
Put, cause to waste.For energy-saving and emission-reduction, now using lithium bromide refrigeration technique, this part used heat of recoverable, realize refrigeration or
Heat purpose.Generally, when remaining hot water inlet temperature at 90 DEG C or so, it is necessary to when freezing, preferred product is hot water single-action
Type lithium bromide adsorption water chilling unit（Flow chart is shown in Fig. 1）, because its coefficient of performance of refrigerating COP is up to 0.75 or so, remaining hot water
Minimum 80 DEG C of outlet temperature, the waste heat water entrance temperature difference are maximum 10 DEG C；If two level, which occurs, from two level absorbs hot water lithium bromide
Absorption chiller（Flow chart is shown in Fig. 2）, the cold water of same quality is produced, the waste heat water entrance temperature difference can be made to be increased to 30 DEG C
Left and right, hot water outlet temperature drop to 60 DEG C, just more, but its coefficient of performance of the remaining hot water heat recovery of same flow
Only 0.4 or so, it is clear that conversion efficiency is again too low.In how making（It is low）Warm remaining hot water cooling extent is big, can more reclaim
（It is low）Warm remaining hot water heat, coefficient of performance value again it is higher in the case of, the cold water for producing same quality meets production technology or life
It is living to use, the mixed economy and social benefit of energy-saving and emission-reduction are realized, turns into one of important topic studied at present.
The content of the invention
In making it is an object of the invention to provide one kind（It is low）Warm remaining hot water cooling extent is big, the more recovery waste heat hydro-thermals of energy
Amount, coefficient of performance value and the higher hot water type lithium bromide absorption cooling water dispenser group that solution series occur with single-action.
What the object of the invention was realized in：A kind of hot water type lithium bromide absorption cooling water that solution series occur with single-action
Unit, including single-action generator, second-stage generator, condenser, evaporator, secondary absorber, first absorber, one-level occur
Device, one-level heat exchanger, two-stage heat exchanger, single-action heat exchanger, cryogenic fluid pump, two level generating pump, one-level generating pump, single-action hair
Raw pump, the pipeline of control system and connecting components, valve etc..It is characterized in that：It is that two level occurs in two level to absorb hot-water type
On lithium bromide adsorption water chilling crew base, increased single-action generator is placed in the high pressure of upper cylinder second-stage generator and condenser
In cavity, single-action generator sets independent liquid dish to be placed in above second-stage generator；Evaporator and secondary absorber are same
In one low pressure volumes, in same middle pressure chamber body, they are placed in lower cylinder for first-stage generator and first absorber.Drive hot water
Series connection enters first-stage generator after being introduced into single-action generator, finally enters second-stage generator；Cooling water series connection is introduced into two level
Enter first absorber after absorber, finally enter condenser；Cold water enters evaporator.Unit internal solution two phases of circulation point
To independent circulation：Second-stage generator, first absorber and two-stage heat exchanger form the circulation of two level solution；Secondary absorber goes out
During the weak solution come is into heated concentration in first-stage generator after the heating of one-level heat exchanger by the lifting of one-level generating pump
Between solution, first-stage generator come out intermediate solution by single-action generating pump lifted through single-action heat exchanger heating after enter single-action send out
It is concentrated solution that raw device, which is heated concentration, and the power of the pressured difference of the concentrated solution that single-action generator comes out and potential difference is handed over through single-action heat successively
Parallel operation, one-level heat exchanger cooling after enter secondary absorber spray is changed into weak solution, this process formed another single-action with
Primary liquor series circulation.
Single-action generator, second-stage generator and condenser are in same high-pressure chamber, are placed in the top of unit, single-action hair
Raw device can also be arranged side by side with second-stage generator, set independent liquid dish, set liquid barrier between them.
It can be spent hot water, conduction oil or other media that used heat is driven in above scheme.Cooling water can also first parallel connection enter
Enter to merge together after secondary absorber, first absorber and enter back into condenser.Cooling water can enter two level with parallel connection and absorb
Device, first absorber and condenser.
Compared with prior art, the advantage of the invention is that：
The present invention makes remaining hot water in single-action by the single-action generator and single-action heat exchanger newly established and above-mentioned brand-new flow
Generator release high-temperature region heat, first-stage generator release in warm area heat, second-stage generator discharge low-temperature space heat, close
Reason make use of remaining hot water warm area, while single-action can make middle pressure chamber pressure is relative to improve with primary liquor series circulation, more adduction
The temperature spot and concentration difference of each circulation of selection of reason, improve unit performance coefficient COP values, and the concentration of single-action generator is dense
The power of the pressured difference of solution and potential difference enters in secondary absorber after single-action heat exchanger, the cooling of one-level heat exchanger successively to be sprayed
Leaching, it is not necessary to increase kinetic pump, still using four canned motor pumps.The coefficient of performance of refrigerating and hot water list of single-action generator solution circulation
Acting type unit is essentially identical, the coefficient of performance of refrigerating and two level hot-water type machine of the circulation of two level solution and the circulation of first-stage generator solution
Group is essentially identical, and both are compound to make the hot-water type unit of solution series occurs in more recovery waste heat hydro-thermal amount while property with single-action
Can the raising of coefficient COP values.For example, working as remaining hot water inlet temperature at 90 DEG C or so, produce and single-effect type unit and diarcs unit
Identical grade cold water（8 DEG C or so of cold water outlet temperature）When, absorbed using the hot water lithium bromide that solution series occur with single-action
Formula handpiece Water Chilling Units, coefficient of performance of refrigerating COP is up to 0.6 or so, and for waste heat water out at 55 DEG C or so, the waste heat water entrance temperature difference can
Up to 35 DEG C or so, it is seen then that greatly improved although the unit performance coefficient COP is more slightly lower than single-effect type unit than diarcs unit,
And hot water cooling extent increases, the heat of remaining hot water more can be fully recycled, realizes mixed economy and the society of energy-saving and emission-reduction
Can benefit.
