The weak solution Sw for being delivered to regenerator 30 is supplied to from weak solution feedway 33, by what is flowed in heat source tube 32 High temperature fluid FH and heated, the evaporation of refrigerant in the weak solution Sw supplied and as concentrated solution Sa, and be accumulated in regeneration The lower part of device 30.At this point, high temperature fluid FH by weak solution Sw capture heat and temperature reduce.In the high temperature fluid that heat source tube 32 flows FH is the fluid after the heat source tube 22 for having passed through evaporator 20.The refrigerant V evaporated from weak solution Sw is as regenerator refrigerant Steam Vg and moved to condenser 40.The concentrated solution Sa of the lower part of regenerator 30 is accumulated in via concentrated solution pipe 35 and by solution pump 35p pressurized delivereds to absorber 10 concentrated solution feedway 13.Pass through solution heat in the concentrated solution Sa that concentrated solution pipe 35 flows Exchanger 38 and weak solution Sw carry out heat exchange and after temperature rise, inflow absorber 10, and from 13 quilt of concentrated solution feedway Supply, is repeated same cycle below.
Concrete example is enumerated, the height during carrying out sorption type heat pump cycle as described above to absorbing liquid S and refrigerant V The variation of the temperature of warm fluid FH and cryogen FL illustrates.With the height of 95 DEG C of heat source tubes for being flowed into evaporator 20 22 Warm fluid FH captures heat by refrigerant liquid Vf and temperature is reduced to 90 DEG C.The high temperature fluid FH flowed out from evaporator 20 is in high-temperature stream After body connecting tube 25 flows, with the heat source tube 32 of 90 DEG C of inflow regenerators 30.The high temperature fluid FH for flowing into heat source tube 32 is dilute Solution S w captures heat and temperature is reduced to 85 DEG C.High temperature fluid FH after the reduction of 30 temperature of regenerator is with 85 DEG C of outflow regenerators 30, and flowed in high temperature fluid discharge pipe 39 and flow into the first heat exchange department 81.
On the other hand, it with the cryogen FL of 32 DEG C of heat conducting pipes for being flowed into condenser 40 42, obtains freezing in regenerator The condensation heat that releases when agent steam Vg is condensed and temperature rise are to 57 DEG C.The cryogen FL flowed out from condenser 40 is in low temperature Fluid connecting line 15 flows and flows into the first heat exchange department 81.In the first heat exchange department 81, flowed in high temperature fluid discharge pipe 39 Heat exchange, 85 DEG C of high-temperature stream are carried out between dynamic high temperature fluid FH and the cryogen FL flowed in cryogen connecting tube 15 Body FH temperature is reduced to 80 DEG C, and 57 DEG C of cryogen FL temperature rises are to 82 DEG C.Temperature is reduced to 80 DEG C of high temperature fluid FH Continuation is flowed, and discharged from absorption type heat exchange system 1 in high temperature fluid discharge pipe 39.The cryogen of temperature rise to 82 DEG C The heat conducting pipe 12 of FL inflow absorbers 10.The cryogen FL for being flowed into heat conducting pipe 12 obtains absorbing evaporator system in concentrated solution Sa Generated during refrigerant vapor Ve absorption heat and temperature rise to 107 DEG C.Cryogen FL after 10 temperature rise of absorber, with 107 DEG C of outflow absorbers 10 are simultaneously supplied to field of employment.
