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 utility model, belongs to air-conditioning and sets
Standby technical 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 at the same time again in（It is low）Warm waste heat, some waste 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 waste heat of recoverable, realize refrigeration or
Heat purpose.Under normal circumstances, 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 10 DEG C maximum；If selecting two level that two level occurs 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 transfer efficiency is again too low.In how making（It is low）Warm remaining hot water cooling extent is big, can more recycle
（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, realize the mixed economy and social benefit of energy-saving and emission-reduction, become one of important topic studied at present.
The content of the invention
The purpose of this utility model is to provide during one kind makes（It is low）Warm remaining hot water cooling extent is big, the more recovery waste heats of energy
Hydro-thermal 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 utility model aim was realized in：A kind of hot water lithium bromide absorbing that solution series occur with single-action
Handpiece Water Chilling Units, including single-action generator, second-stage generator, condenser, evaporator, secondary absorber, first absorber, level-one hair
Raw device, level-one heat exchanger, two-stage heat exchanger, single-action heat exchanger, cryogenic fluid pump, two level generating pump, level-one generating pump, single-action
Generating 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
On type lithium bromide adsorption water chilling crew base, increased single-action generator is placed in the height of upper cylinder second-stage generator and condenser
Press in cavity, single-action generator sets independent liquid dish to be placed in above second-stage generator；Evaporator and secondary absorber exist
In same low pressure volumes, in same middle pressure chamber body, they are placed in lower cylinder for first-stage generator and first absorber.Driving heat
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
Enter first absorber after level absorber, finally enter condenser；Cold water enters evaporator.Unit internal solution circulation point two
Relatively independent circulation：Second-stage generator, first absorber and two-stage heat exchanger form the circulation of two level solution；Secondary absorber
Weak solution out is lifted by level-one generating pump
Intermediate solution, the intermediate solution that first-stage generator comes out is lifted by single-action generating pump enters single-action after the heating of single-action heat exchanger
It is concentrated solution that generator, which is heated concentration, and the concentrated solution that single-action generator comes out is by pressure difference and the power of potential difference successively through single-action heat
Enter secondary absorber spray after exchanger, the cooling of level-one heat exchanger and be changed into weak solution, this process forms 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 waste heat is driven in above scheme.Cooling water can also it is first in parallel into
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 utility model has the advantage of：
The utility model makes waste heat by the single-action generator and single-action heat exchanger newly established and above-mentioned brand-new flow
Water discharges low temperature in single-action generator release high-temperature region heat, in first-stage generator release middle warm area heat, in second-stage generator
Area's heat, reasonably make use of remaining hot water warm area, while single-action can make middle pressure chamber pressure is opposite to carry with primary liquor series circulation
Height, more reasonably chooses the temperature spot and concentration difference of each circulation, improves unit performance coefficient COP values, and single-action occurs
The concentrated solution of device concentration enters two level after single-action heat exchanger, the cooling of level-one heat exchanger successively by pressure difference and the power of potential difference
Spray in absorber, it is not necessary to increase kinetic pump, still using four canned motor pumps.The refrigeration performance system of single-action generator solution circulation
Number is essentially identical with hot water single-effect type unit, the coefficient of performance of refrigerating and two of the circulation of two level solution and the circulation of first-stage generator solution
Level hot-water type unit is essentially identical, both are compound to make the hot-water type unit of solution series occurs in more recovery waste heat hydro-thermals with single-action
Coefficient of performance value improves while amount.For example, when remaining hot water inlet temperature at 90 DEG C or so, produce with single-effect type unit and
The identical grade cold water of diarcs unit（8 DEG C or so of cold water outlet temperature）When, using the hot-water type that solution series occur with single-action
Lithium bromide adsorption water chilling unit, coefficient of performance of refrigerating COP up to 0.6 or so, waste heat water out at 55 DEG C or so, remaining hot water into
The temperature difference is exported up to 35 DEG C or so, it is seen then that although the unit performance coefficient COP is more slightly lower than single-effect type unit than diarcs machine
Group greatly improves, and hot water cooling extent increases, and more can fully recycle the heat of remaining hot water, realize the comprehensive of energy-saving and emission-reduction
Close economic and social benefit.
