Second class absorption heat pump

The utility model discloses a second class absorption heat pump, it includes generator, condenser, absorber, heat exchange assemblies and evaporimeter, be provided with first heat transfer pipeline and second heat transfer pipeline in the absorber, feed through respectively driving heat source and quiet heat exchange assemblies by heating medium, intensified through the cubic by heating medium inthis heat pump: it is exothermic to being heaied up by the heating medium heating for the liquefaction of condenser steam for the first time, the driving heat source who is for the second time being flowed out by the absorber intensifies to its heating, it heaies up to its heating to be for the third time the inside solution of absorber, promptly by heating medium's intensification energy source in the condenser steam heat of liquefaction can with concentrated solution in the absorber by the dilutent heat energy that releases, energy that heat pump set can retrieve steam liquefaction release in the condenser is for by
