Lithium bromide absorption refrigerator

Abstract

The invention discloses a lithium bromide absorption refrigerator. The lithium bromide absorption refrigerator comprises an absorber, a generator, a condenser, a gas-liquid separator, a membrane separation filter and an evaporator, a dilute solution outlet of the absorber is connected with a liquid inlet of the membrane separation filter, a liquid outlet of the membrane separation filter is connected with a concentrated solution inlet of the absorber, a water outlet of the membrane separation filter is connected with the condenser, one outlet of the gas-liquid separator is a refrigerant steamoutlet, and is connected with the generator, the other outlet of the gas-liquid separator is a concentrated solution outlet, and is connected with a heat exchanger, an outlet of the generator is connected with the condenser, and a concentrated solution outlet of the heat exchanger is connected with the absorber, the condenser is connected with the evaporator through a throttling valve, and the evaporator is connected with the absorber. According to the lithium bromide absorption refrigerator, through the combination of the heat exchanger, the generator, the condenser and the like, the heat source utilization rate is further improved, the heat exchange efficiency is improved, the environment is not polluted, the energy-saving effect is good, the daily operation and maintenance cost is low,and good economic and social benefits are achieved.

Description

technical field [0001] The invention specifically relates to a lithium bromide absorption refrigerator. Background technique [0002] The lithium bromide absorption unit uses water as the refrigerant, lithium bromide solution as the absorbent, uses steam, hot water or fuel, gas direct combustion heat or other waste heat as the heat source, and uses the principle of evaporation and absorption to achieve refrigeration. The lithium bromide absorption refrigeration units currently used can be divided into single-effect, double-effect, triple-effect or multi-effect absorption refrigerators according to the working mode. According to the type of driving heat source, it can be divided into steam type, direct combustion type, hot water type, etc. Existing lithium bromide absorption refrigerating machine has the following deficiencies: the concentrated use of lithium bromide dilute solution is distillation, which will consume a large amount of heat energy. Inevitable pollution; In ...
