Double-effect regeneration absorption-generation system and regeneration third-class absorption heat pump

Abstract

The invention provides a double-effect regeneration absorption-generation system and a regeneration third-class absorption heat pump, and belongs to the technical field of heat pumps. The double-effect regeneration absorption-generation system consists of a first generator, a second generator, a first absorber, a second absorber, a third absorber, a steam bleeding chamber, a plurality of solution pumps and a plurality of solution heat exchangers, wherein the first generator provides refrigerant steam for a condenser; the second generator provides the refrigerant steam for the second absorber; the steam bleeding chamber provides the refrigerant steam for the third absorber; an evaporator provides the refrigerant steam for the first absorber; the condenser provides refrigerant liquid for the evaporator through a refrigerant liquid pump; the first absorber, the third absorber or the second absorber supplies heat to the outside; and the condenser releases low-temperature heat, so that the regeneration third-class absorption heat pump with the double-effect regeneration process is formed.

Description

Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization heat pumps. Background technique: [0002] In the third type of absorption heat pump process that uses high-temperature generators and high-temperature absorbers to realize the change of solution concentration, a heat recovery process is formed between the high-temperature generators and high-temperature absorbers, which can not only improve the performance of the third type of absorption heat pumps. The heating temperature can also make the third type of absorption heat pump have the advantages of adjustable heating parameters, continuous performance index and adaptable to variable working conditions. However, when the temperature difference between the high-temperature driving heating medium and the heated medium is large, if the high-grade heat load of the high-temperature driving heating medium only undergoes a reheating process, the temperature difference canno...
