DOUBLE-EFFECT HEAT-RECOVERING ABSORBING-GENERATING SYSTEM AND HEAT-RECOVERING THIRD-TYPE ABSORPTION HEAT PUMP

摘要

A double-effect heat-recovering absorbing-generating system and a heat-recovering third-type absorption heat pump. The double-effect heat-recovering absorbing-generating system comprises a first generator (1), a second generator (2), a first absorber (3), a second absorber (4), a third absorber (5), a steam distributing chamber (6), a plurality of solution pumps (7, 8, and 9), and a plurality of solution heat exchangers (11, 12, and 13). The first generator (1) provides refrigerant steam for a condenser (15), the second generator (2) provides the refrigerant steam for the first absorber (3), the steam distributing chamber (6) provides the refrigerant steam for the third absorber (5), an evaporator (16) provides the refrigerant steam for the second absorber (4), the condenser (15) provides refrigerant liquid for the evaporator (16) through a throttle valve (17), the second absorber (4) and the condenser (15) provide heat to the external, the third absorber (5) or the third absorber (5) and the first absorber (3) send out low-temperature heat, so that the heat-recovering third-type absorption heat pump with a double-effect heat-recovering flow can be formed.
