Cool double-effect lithium bromide spray absorption type refrigeration cycle system

Abstract

The invention relates to a cool double-effect lithium bromide spray absorption type refrigeration cycle system. A refrigerant water passage of a condenser is divided into three paths; in the first path, the condenser is communicated with an evaporator; in the second path, one end of the second refrigerant water passage is communicated with the condenser, and the other end of the second refrigerant water passage passes through a first absorber to be communicated with a second absorber; in the third path, a liquid storage device is communicated with the condenser, one end of a second connecting pipe is communicated with the liquid storage device, the other end of the second connecting pipe is communicated with a boiler, one end of a first connecting pipe is communicated with a boiler, the other end of the first connecting pipe is communicated with the condenser, the other end of the connecting pipe is communicated with an ejector, one end of a first refrigerant water vapor pipeline is communicated with the ejector, the other end of the first refrigerant water vapor pipeline is communicated with a generator, the first absorber is communicated with an evaporator, one end of a medium concentration solution pipeline is communicated with the first absorber, the other end of the medium concentration solution pipeline is communicated with the second absorber, one end of a first dilute solution pipeline and one end of a first concentrated solution pipeline are both communicated with the second absorber, and the other ends of the first dilute solution pipeline and the first concentrated solution pipeline are both communicated with the generator. The system is used in an absorption type 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, ...
