Description

technical field [0001] The invention relates to an absorption refrigerating cycle system, in particular to a condensing and boosting lithium bromide spray absorption refrigerating cycle system. Background technique [0002] Traditional absorption refrigeration cycle systems such as figure 2 As shown, it is mainly composed of a generator 1, a condenser 2, an evaporator 3, an absorber 5, a solution heat exchanger 6, a solution pump 10, etc., and connected pipelines. Under the heating action of the first high-level heat source 25, the generator 1 condenses the lithium bromide solution in it to generate relatively high-temperature and high-pressure refrigerant water vapor and enters the condenser 2 through the first refrigerant water vapor pipeline 42 to condense, and the condensation process releases The heat is absorbed by the second cooling heat source 45, and the refrigerant water generated after condensation is throttled and depressurized by the expansion throttling device...
