First regenerator G1 and Second reactivator G2 are via the first concentrated solution effuser 34 and the second concentrated solution effuser 38 connections, but when the operating of absorption heat pump 1, part (the first concentrated solution effuser 34 and the second concentrated solution effuser of connection 38) absorbed liquid S fluid-tight, thus the gas phase portion of the two is not connected to, the internal pressure of the two can obtain mutually different value.First is cold Condenser C1 is connect with the second condenser C2 via the first refrigerant liquid effuser 44 and second refrigerant liquid stream outlet pipe 48, but When absorption heat pump 1 operates, the part (the first refrigerant liquid effuser 44 and second refrigerant liquid stream outlet pipe 48) of connection By refrigerant liquid Vf fluid-tight, thus the gas phase portion of the two is not connected to, and the internal pressure of the two can obtain mutually different value.From above-mentioned Content is not connected to (independence) mutually with the gas phase portion of the second regeneration condensation tank body 40 it is found that the first regeneration condenses tank body 30, can Keep the internal pressure of the two different.

Next, illustrating the effect of absorption heat pump 1 referring to Fig. 2 together with Fig. 1.Fig. 2 is Du's timberline of absorption heat pump 1 Figure.In the Dühring's diagram of Fig. 2, the longitudinal axis is the dew-point temperature of refrigerant (being in the present embodiment water), and horizontal axis is absorbing liquid The temperature of (being in the present embodiment LiBr aqueous solution).Upper inclined line indicates the isoconcentrate of absorbing liquid to the right, more turns right Concentration is higher, lower more concentration of turning left.In addition, dew-point temperature shown in the longitudinal axis and saturation pressure are in corresponding relationship, thus The steam of refrigerant is in the absorption cycle of the present embodiment of saturated vapor, and the longitudinal axis, which can also be regarded as, indicates that capital equipment (is inhaled Receive device, evaporator, regenerator, condenser) internal pressure.

In the first condenser C1, receive the first regenerator refrigerant vapour Vg1 evaporated in the first regenerator G1, and benefit It is cooled down used in the cooling water Y of the first condensation heat transfer pipe 41 flowing and condenses it and become the first refrigerant liquid Vf1.? In two condenser C2, receive the Second reactivator refrigerant vapour Vg2 evaporated in Second reactivator G2, and using in the second condensation The cooling water Y that heat-transfer pipe 45 flows is cooled down and is condensed it and become second refrigerant liquid Vf2.Cooling water Y is cold first It after solidifying heat-transfer pipe 41 flows, flows via cooling water connecting pipe for water 74 in the second condensation heat transfer pipe 45, thus is passed in the first condensation Temperature when heat pipe 41 flows is lower than the temperature in the flowing of the second condensation heat transfer pipe 45, the internal pressure (TC1) of the first condenser C1 Internal pressure (TC2) than the second condenser C2 is low.The liquid level of the first refrigerant liquid Vf1 inside first condenser C1, it is colder than second The liquid level of second refrigerant liquid Vf2 in condenser C2 is higher by the interior amount forced down of its second condenser of inner pressure ratio C2.However, at this In embodiment, the first regeneration condensation tank body 30 inside forced down is configured at the top of the second regeneration condensation tank body 40, it is thus possible to The liquid level for suitably maintaining the first refrigerant liquid Vf1 in the first condenser C1 and the second refrigerant liquid in the second condenser C2 The liquid level of Vf2.Therefore being able to suppress the first condensation heat transfer pipe 41 submerges the first refrigerant liquid Vf1 and the second condensation heat transfer pipe 45 Submerge second refrigerant liquid Vf2.

In addition, the biggish feelings of difference of the internal pressure in the internal pressure and the second regeneration condensation tank body 40 of the first regeneration condensation tank body 30 Under condition (under the inlet temperature of cooling water Y and the biggish situation of the difference of outlet temperature), if in second refrigerant liquid Vf2 from internal pressure height The second condenser C2 outflow second refrigerant liquid stream outlet pipe 48 and the second concentrated solution Sa2 flowed out from Second reactivator G2 Second concentrated solution effuser 38, the pressure regulation devices such as setting throttle orifice, valve, come the second refrigeration reduced in the second condenser C2 In the difference and Second reactivator G2 of the liquid level of the first refrigerant liquid Vf1 in the liquid level of agent liquid Vf2 and the first condenser C1 The difference of the liquid level of the first concentrated solution Sa1 in the liquid level of second concentrated solution Sa2 and the first regenerator G1 can then reduce first again The difference of the setting height of the solidifying tank body 30 of raw food and the second regeneration condensation tank body 40.

The first refrigerant liquid effuser 44 is flowed out in the first refrigerant liquid Vf1 that the first condenser C1 is generated, second The second refrigerant liquid Vf2 that condenser C2 is generated flows out to second refrigerant liquid stream outlet pipe 48.In the first refrigerant liquid effuser First refrigerant liquid Vf1 of the 44 flowings and second refrigerant liquid Vf2 flowed in second refrigerant liquid stream outlet pipe 48, flows respectively Enter refrigerant liquid collecting fitting 54 and is mixed to refrigerant liquid Vf.Refrigerant liquid Vf in refrigerant liquid collecting fitting 54 is collaborated Refrigerant fluid pump 54p pressurized delivered, and branch to the first refrigerant liquid ingress pipe 23 and second refrigerant liquid ingress pipe 27.? The refrigerant liquid of one refrigerant liquid ingress pipe 23 flowing is dissipated from the first refrigerant liquid spreading nozzle 22 into the first evaporator E1 Cloth.On the other hand, the refrigerant liquid flowed in second refrigerant liquid ingress pipe 27, from second refrigerant liquid spreading nozzle 26 to the It is spread in two evaporator E2.

In the first evaporator E1, the refrigerant liquid Vf spread from the first refrigerant liquid spreading nozzle 22 is steamed first The heat source fluid H that hair heat-transfer pipe 21 flows is heated and is evaporated, and becomes the first evaporator refrigerant steam Ve1.In the first evaporator The first evaporator refrigerant steam Ve1 that E1 is generated is mobile to the first absorber A1 being connected to the first evaporator E1.Another party Face, in the second evaporator E2, the refrigerant liquid Vf spread from second refrigerant liquid spreading nozzle 26, by the second evaporation heat transfer The heat source fluid H that pipe 25 flows is heated and is evaporated, and becomes the second evaporator refrigerant steam Ve2.It is generated in the second evaporator E2 The second evaporator refrigerant steam Ve2, it is mobile to the second absorber A2 for being connected to the second evaporator E2.Heat source fluid H exists After the flowing of first evaporation heat transfer pipe 21, flowed via heat source evaporation connecting tube 72 in the second evaporation heat transfer pipe 25, thus first Temperature when evaporation heat transfer pipe 21 flows is higher than the temperature in the flowing of the second evaporation heat transfer pipe 25, the internal pressure of the first evaporator E1 (TE1) internal pressure (TE2) than the second evaporator E2 is high.

In the first absorber A1, the first concentrated solution Sa1 is spread from the first concentrated solution spreading nozzle 12, and the first of the distribution Concentrated solution Sa1 is absorbed from mobile the first next evaporator refrigerant steam Ve1 of the first evaporator E1.Absorb the first evaporator refrigeration The first concentrated solution Sa1 concentration after agent steam Ve1 reduces, and becomes the first weak solution Sw1 (A1a~A1b).In the first absorber A1 In, it is generated when the first concentrated solution Sa1 absorbs the first evaporator refrigerant steam Ve1 and absorbs heat.Using the absorption heat to One absorbs the heating target fluid W heating that heat-transfer pipe 11 flows.Absorb the first evaporator refrigerant steam Ve1 and dense molten from first The first weak solution Sw1 that liquid Sa1 concentration reduces is stored in the lower part of the first absorber A1.In the second absorber A2, second is dense Solution S a2 is spread from the second concentrated solution spreading nozzle 16, and the second concentrated solution Sa2 of the distribution absorbs mobile from the second evaporator E2 The the second evaporator refrigerant steam Ve2 come.The second concentrated solution Sa2 concentration after absorbing the second evaporator refrigerant steam Ve2 It reduces, becomes the second weak solution Sw2 (A2a~A2b).In the second absorber A2, the second evaporation is absorbed in the second concentrated solution Sa2 It is generated when device refrigerant vapour Ve2 and absorbs heat.The heating target stream that heat-transfer pipe 15 flows is absorbed to second using the absorption heat Body W heating.The the second weak solution Sw2 storage for absorbing the second evaporator refrigerant steam Ve2 and being reduced from the second concentrated solution Sa2 concentration It is stored in the second lower part absorber A2.

At this point, the internal pressure (TE1) for the first absorber A1 being connected to the first evaporator E1 is connected to than with the second evaporator E2 The second absorber A2 internal pressure (TE2) it is high.In addition, heating target fluid W second absorb heat-transfer pipe 15 flow after, first Heat-transfer pipe 11 is absorbed to flow, thus in the temperature ratio of the heating target fluid W of the first absorber A1 flowing in the second absorber A2 The temperature of the heating target fluid W of flowing is high, and the temperature (A1b) of the first weak solution Sw1 compares the temperature of the second weak solution Sw2 (A2b) high.Here, be compared with the situation that evaporation tank body is one is absorbed, in the case where absorbing evaporation tank body is one, Absorber internal pressure close in the absorption heat pump 1 of present embodiment in the internal pressure (TE2) of the second absorber A2 forced down, from suction Receive the weak solution temperature of device outflow, the temperature of the first weak solution Sw1 high close to the temperature in the absorption heat pump 1 of present embodiment It spends (A1b).In the absorption heat pump 1 of present embodiment, the internal pressure (TE1) of the first absorber A1 is interior than the second absorber A2 In the case that pressure (TE2) is high, thus the concentration of the first weak solution Sw1 is one than absorption evaporation tank body, flowed out from absorber The amount that the low internal pressure of weak solution concentration is higher by.In addition, the second weak solution Sw2's is dense in the absorption heat pump 1 of present embodiment In the case that degree is one than absorbing evaporation tank body, the low absorbing liquid temperature of the weak solution concentration flowed out from absorber is reduced Amount.Therefore in the absorption heat pump 1 of present embodiment, the concentration of the first weak solution Sw1 and the second weak solution Sw2 can be made In the case where being one than absorption evaporation tank body, the weak solution concentration flowed out from absorber is low, can make output increase.In this way, If the sequence for the tank body for flowing supplying heat source fluid H makes from the first evaporator E1 to the second evaporator E2 for heating target Fluid W flowing tank body sequence it is reversed therewith, and according to from the second absorber A2 to the sequence of the first absorber A1 for heating Subject fluid W flowing then is suitable for reducing the concentration of the first weak solution Sw1 and the concentration of the second weak solution Sw2.

The liquid level of the second weak solution Sw2 inside second absorber A2 is than the first weak solution Sw1 in the first absorber A1 Liquid level be higher by its first absorber of inner pressure ratio A1 in the amount forced down.However, in the present embodiment, second inside forced down inhales Receive the top that evaporation tank body 20 is configured at the first absorption evaporation tank body 10, it is thus possible to suitably maintain in the second absorber A2 The liquid level of the liquid level of second weak solution Sw2 and the first weak solution Sw1 in the first absorber A1.Therefore it is able to suppress the first absorption Heat-transfer pipe 11 submerges the absorption heat-transfer pipe 15 of the first weak solution Sw1 and second and submerges the second weak solution Sw2.

In addition, the situation that the difference for the internal pressure that the internal pressure and second that absorb evaporation tank body 10 first absorb evaporation tank body 20 is big Under (in the case that the inlet temperature of heat source fluid H and the difference of outlet temperature are big), if for the first weak solution Sw1 it is high from internal pressure The pressure regulation devices such as throttle orifice, valve are arranged in first weak solution effuser 14 of the first absorber A1 outflow, to reduce the first suction The difference for receiving the liquid level of the second weak solution Sw2 in the liquid level and the second absorber A2 of the first weak solution Sw1 in device A1, then can Reduce the difference for the setting height that first absorbs evaporation tank body 10 and the second absorption evaporation tank body 20.

The first weak solution effuser 14 is flowed out in the first weak solution Sw1 that the first absorber A1 is generated, is absorbed second The second weak solution Sw2 that device A2 is generated flows out to the second weak solution effuser 18.The of the flowing of the first weak solution effuser 14 One weak solution Sw1 and the second weak solution effuser 18 flowing the second weak solution Sw2 separately flow into weak solution collecting fitting 51, And it is mixed to weak solution Sw (Ab).Weak solution collecting fitting 51 flow weak solution Sw solution heat exchanger 52 with it is dense molten Liquid Sa carries out heat exchange after temperature reduction, branches to the first weak solution ingress pipe 33 and the second weak solution ingress pipe 37.? The weak solution Sw of first weak solution ingress pipe 33 flowing is spread from the first weak solution spreading nozzle 32 into the first regenerator G1.Separately On the one hand, in the weak solution Sw of the second weak solution ingress pipe 37 flowing from the second weak solution spreading nozzle 36 to Second reactivator G2 Interior distribution.

At this point, then evaporating saturation temperature TE1 and condensing the difference of saturation temperature TC1 is 30 DEG C if common operating condition More than, thus the difference of the internal pressure of the first absorber A1 and the internal pressure of the first regenerator G1, become and is spread in the first regenerator G1 Sufficient pressure difference needed for weak solution Sw, so as to steadily spread weak solution Sw in the first regenerator G1.It is absorbing In formula heat pump 1, the direct circulation of absorbing liquid S is not present between the first regenerator G1 and Second reactivator G2, thus the The drop that the distribution pressure for obtaining absorbing liquid S is not needed between one regenerator G1 and Second reactivator G2, can reduce first Difference (the height of the first regeneration condensation tank body 30 and the second regeneration condensation tank body 40 of the height of regenerator G1 and Second reactivator G2 Difference).

In the first regenerator G1, the weak solution Sw spread from the first weak solution spreading nozzle 32 is passed in the first regeneration The heat source fluid H heating that heat pipe 31 flows, so that the refrigerant in the weak solution Sw spread evaporates and becomes the first concentrated solution Sa1 (G1a~G1b), and it is stored in the lower part of the first regenerator G1.The refrigerant evaporated from weak solution Sw is as the first regenerator system Refrigerant vapor Vg1 is mobile to the first condenser C1.On the other hand, in Second reactivator G2, from the second weak solution spreading nozzle The 36 weak solution Sw spread are heated by the heat source fluid H flowed in the second regeneration heat-transfer pipe 35, thus in the weak solution Sw spread Refrigerant evaporation and become the second concentrated solution Sa2 (G2a~G2b), and be stored in the lower part of Second reactivator G2.From weak solution The refrigerant of Sw evaporation is mobile to the second condenser C2 as Second reactivator refrigerant vapour Vg2.As described above, the first regeneration The internal pressure (TC1) for condensing tank body 30 is lower than the internal pressure (TC2) of the second regeneration condensation tank body 40.In addition, heat source fluid H second again After raw heat-transfer pipe 35 flows, flowed in the first regeneration heat-transfer pipe 31, thus the temperature of the heat source fluid H in Second reactivator G2 flowing The temperature for spending the heat source fluid H than flowing in the first regenerator G1 is high, and the temperature (G2b) of the second concentrated solution Sa2 is denseer than first molten The temperature (G1b) of liquid Sa1 is high.Here, the situation for being one with regeneration condensation tank body is compared, it is one in regeneration condensation tank body In the case where a, regenerator internal pressure is close in the high Second reactivator G2 of the internal pressure in the absorption heat pump 1 of present embodiment It presses (TC2), from the concentrated solution temperature that regenerator flows out close to low first dense of the temperature in the absorption heat pump 1 of present embodiment The temperature (G1b) of solution S a1.In the absorption heat pump 1 of present embodiment, internal pressure (TC1) ratio second of the first regenerator G1 In the case that the internal pressure (TC2) of regenerator G2 is low, thus the concentration of the first concentrated solution Sa1 is one than regeneration condensation tank body, from The strong solution concentration of regenerator outflow is higher by the interior amount forced down.In addition, second is dense in the absorption heat pump 1 of present embodiment In the case that the concentration of solution S a2 is one than regeneration condensation tank body, the strong solution concentration flowed out from regenerator is higher by absorbing liquid The high amount of temperature.Therefore, the concentration of the first concentrated solution Sa1 and the second concentrated solution Sa2 can be made than regeneration condensation tank body one In the case where a, the strong solution concentration flowed out from regenerator is high, and output can be made to increase.In this way, if flowing Cooling Water Y The sequence of tank body be from the first condenser C1 to the second condenser C2, and make supplying heat source fluid H flow tank body sequence therewith It reversely and according to the sequence supplying heat source fluid H from Second reactivator G2 to the first regenerator G1 flows, is then suitable for improving first dense The concentration of the concentration of solution S a1 and the second concentrated solution Sa2.

First concentrated solution effuser 34 is flowed out to by the first concentrated solution Sa1 that the first regenerator G1 is generated, by the second regeneration The second concentrated solution Sa2 that device G2 is generated flows out to the second concentrated solution effuser 38.The of the flowing of the first concentrated solution effuser 34 One concentrated solution Sa1 and the second concentrated solution Sa2 flowed in the second concentrated solution effuser 38, separately flows into concentrated solution collecting fitting 53 And it is mixed to concentrated solution Sa (Gb).Concentrated solution Sa in concentrated solution collecting fitting 53 pumps 53p pressurized delivered by interflow concentrated solution, And flowed towards the first absorber A1 and the second absorber A2, carry out heat exchange in solution heat exchanger 52 and weak solution Sw and After temperature rises, the first concentrated solution ingress pipe 13 and the second concentrated solution ingress pipe 17 are branched to.In the first concentrated solution ingress pipe The concentrated solution Sa of 13 flowings is spread from the first concentrated solution spreading nozzle 12 into the first absorber A1, repeats above-mentioned circulation later. On the other hand, it in the concentrated solution Sa of the second concentrated solution ingress pipe 17 flowing, is absorbed from the second concentrated solution spreading nozzle 16 to second It is spread in device A2, repeats above-mentioned circulation later.In absorption heat pump 1, between the first absorber A1 and the second absorber A2 There is no the direct circulations of absorbing liquid S, thus do not need between the first absorber A1 and the second absorber A2 for obtaining The drop of the distribution pressure of absorbing liquid S can reduce difference (the first absorption steaming of the height of the first absorber A1 and the second absorber A2 It sends out tank body 10 and second and absorbs the difference for evaporating the height of tank body 20).
