Variable effect desorber-resorber absorption cycle

An absorption heat pump/refrigeration system having a single absorbent solution flowing therethrough comprising:

• a first generator means operating within a first temperature range for heating a weak absorbent solution to generate a vaporized refrigerant and a strong refrigerant solution;
• a second generator means operating at a second lower temperature range relative to said first generator means for heating a second weak absorbent solution to vaporize refrigerant;
• a condenser means cooperating with said first and second generator means for condensing the vaporized refrigerant generated therein;
• an evaporator means for receiving the condensed refrigerant from said condenser means, said condensed refrigerant in heat exchange relationship with a heat source means for vaporizing said condensed refrigerant within said evaporator means;
• an absorber means for receiving the vaporized condensed refrigerant from said evaporator means in combination with a strong absorbent solution to absorb the refrigerant in the absorbent for generating a weak solution;
• a desorber means for receiving said generated weak solution from said absorber means, and generating a refrigerant vapor therein;
• a resorber means for receiving said refrigerant vapor from said desorber means in combination with said strong refrigerant solution of said first generator means for generating a resorber solution;
• and
• means for controlling the flow of said refrigerant vapor from said desorber means to said resorber means to control the capacity of the absorption system.
