Abstract

A cold double-effect lithium bromide jet absorption refrigeration cycle system, the refrigerant water path of the condenser is divided into three paths, one path: the condenser communicates with the evaporator, and the second path: one end of the second refrigerant water path communicates with the condenser, The other end passes through the first absorber and communicates with the second absorber, three-way: the liquid storage device communicates with the condenser, one end of the second connecting pipe communicates with the liquid storage device, and the other end communicates with the boiler, and one end of the first connecting pipe communicates with the The boiler is connected, the other end is connected with the ejector, one end of the third connecting pipe is connected with the condenser, and the other end is connected with the ejector, one end of the first refrigerant water vapor pipeline is connected with the ejector, and the other end is connected with the generator. One absorber communicates with the evaporator, one end of the intermediate concentration solution pipeline communicates with the first absorber, the other end communicates with the second absorber, one end of the first dilute solution pipeline and the first concentrated solution pipeline connect with the second absorber Connected to the generator, and the other end is connected to the generator. The invention is used in an absorption water source heat pump system.

Description

technical field [0001] The invention relates to an absorption refrigeration cycle system, in particular to a cold double-effect lithium bromide injection absorption refrigeration cycle system. Background technique [0002] Traditional absorption refrigeration cycle systems such as Figure 12 As shown, it is mainly composed of a generator 1, a condenser 2, an evaporator 3, a second absorber 5, a solution heat exchanger 6, a first solution pump 10 and connected pipelines. Under the action of an external heat source, the generator 1 concentrates the lithium bromide solution in it to generate high-temperature and high-pressure refrigerant water vapor, which enters the condenser 2 through the first refrigerant water vapor pipeline 11 to condense, and the condensed low-temperature The refrigerant water enters the evaporator 3 through the first refrigerant water channel 12 after throttling and depressurizing through the first throttling expansion device 8, and in the evaporator 3, ...
