Description

With the triple effect is the two-stage first class absorption heat pump of the first order
Technical field:
The invention belongs to low temperature exhaust heat utilization and absorption type heat pump.
Background technology:
Satisfy that to make the absorption heat pump/refrigeration unit that is adopted have high as far as possible performance index under the prerequisite of heated medium heat demand be the First Principles that follow.Because the variation of the parameter of the cooled medium of waste heat medium, heated medium and driving thermal medium, corresponding requirements has the heat pump flowsheet between the different operating parameter region, and the heat pump/refrigerating unit that promptly needs different thermodynamic parameters and thermodynamic property satisfies concrete demand.
In absorption heat pump, triple-effect first category absorption heat pump has the high advantage of performance index, but also has tangible deficiency can not have the interval and higher heating parameter of heat supply temperature of broad one by one.When the initial temperature of heated medium is suitable for adopting the triple-effect first category absorption heat pump flow process of two heat supply ends and the art section is heated temperature when having exceeded its heat capacity, in order to obtain higher performance index and to satisfy the heat demand of using of heated medium, will carry out such consideration in the heat pump flowsheet arrangement: starting stage of heated medium is adopted one or two heat supply end of triple-effect first category absorption heat pump of the two ends heat supply that adapts, and the latter half of heated medium is adopted higher and the heat pump flowsheet that the heat supply temperature interval is adjacent of heat supply temperature.A heat supply end in the employing triple-effect first category absorption heat pump is used to provide the initial segment heat demand of heated medium, utilize its another heat supply end to provide the low temperature thermic load to the higher heat pump flowsheet of heat supply temperature, the occasion of heated medium temperature range broad can be satisfied, and higher relatively performance index can be obtained.The concrete technical scheme that is adopted is exactly that the absorber of triple-effect first category absorption heat pump is used for low-temperature zone heat demand to heated medium, the refrigerant vapour that its low pressure generator discharges is used for providing refrigerant vapour to the absorber of second heat pump flowsheet, the absorber of second heat pump flowsheet and condenser provide the elevated temperature heat demand to heated medium, obtain thermodynamic parameter on triple effect, have part triple effect thermodynamic property, be the first order and two-stage first class absorption heat pump with the triple effect with three heat supply ends.
Similar therewith and distinguishing situation is, when the interval broad of the variations in temperature of heated medium and when changing, adopt the heat pump flowsheet of above-mentioned three heat supply ends to exist such problem again: when the heated medium temperature is hanged down, the heating demand of second heat pump flowsheet decreases, cause the refrigerant vapour amount in the whole heat pump flowsheet to reduce, the performance index of source pump is constant substantially; This moment, first heat pump flowsheet just can't be brought into play low and the advantage that performance index is high of its heat supply temperature.Increase by second condenser and solve this problem as second heat supply end of first order flow process, obtaining with the triple effect is the first order and the two-stage first class absorption heat pump with four heat supply ends.

At first, when needs were heated to maximum temperature with heated medium by initial temperature, such source pump was according to the highest heat supply temperature and oepration at full load.
Secondly, when the heated medium finishing temperature reduces, reduce the driving thermic load of the 4th generator 4 this moment, then make the refrigerant vapour amount that enters condenser 7 reduce on the one hand, the thermic load that condenser 7 offers heated medium reduces; The feasible on the other hand solution concentration reduction that enters second absorber 6 from the 4th generator 4, and then cause second absorber, 6 interior solution to absorb the formed temperature reduction of refrigerant vapour, the thermic load that second absorber 6 offers heated medium reduces, and has also reduced simultaneously the absorption from the refrigerant vapour of the 3rd generator 3.
The 3rd, reduction along with the external heating demand in the second level, such source pump also decreases the afterheat utilization amount, then the thermic load of first absorber 5 reduces, the temperature that heated medium enters second condenser 20 reduces, the temperature difference between thermal medium of second condenser 20 (mainly being the refrigerant vapour from the 3rd generator 3) and the cold medium (heated medium of second condenser 20 of flowing through) strengthens, the thermic load of second condenser 20 increases, and the refrigerant vapour that the 3rd generator 3 produces then can enter in second condenser 20 more; Though the refrigerant vapour amount that first absorber 5 absorbs is reducing, but the refrigerant vapour that absorbs is finally come out by the 3rd generator 3 and the 4th generator 4 and satisfies second condenser, 20 required ratios to increase again, promptly this moment is in the whole heat supply flow process of source pump, two heat supply ends of first order flow process load increases and the ratio of occupying whole thermic loads increases simultaneously, this makes source pump performance index under the highest non-heat supply temperature increase, thereby makes source pump have higher combination property index.Second condenser 20 is taked rationally to reach optimal design, then can make such source pump have higher combination property index.
By contrast, be the first order with the triple effect and have in the two-stage first class absorption heat pump of three heat supply ends that the refrigerant vapour amount that first absorber, 5 flash-pots 8 absorb is must be the 4th generator 4 in whole comes out and provide to condenser 7; Therefore, when the source pump heating demand reduced, the refrigerant vapour amount that first absorber 5 absorbs decreased, and the performance index of source pump only has small fluctuation.
