The invention provides the first-type absorption heat pump with multi-terminal heat supply which belongs to the area of low-temperature waste heat utilization and refrigeration technique. It mainly comprises a generator, the first absorber, the second absorber, an absorption-evaporator, a condenser, a evaporator, a throttle, a solution pump or the second throttle, the first solution pump, the second solution pump, the first solution heat exchanger and the second solution heat exchanger. The second absorber provides solution for generator. The generator provides solution for the first absorber. The first absorber provides solution for the absorption-evaporator. The absorption-evaporator provides solution for the second absorber. The generator provides the refrigerant vapor for condenser. The condenser provides the refrigerant liquid for evaporator. The evaporator provides respectively the refrigerant vapor for the first absorber and the absorption-evaporator. The evaporator provides the refrigerant liquid for the absorption-evaporator and then absorbs heat and becomes refrigerant vapor providing for the second absorber. The first absorber, the condenser and the second absorber provide heat. The first-type absorption heat pump with multi-terminal heat supply is thereby formed. |
