Lithium bromide absorbing refrigerator of membrane separation concentrating solution

Abstract

The invention discloses a lithium bromide absorbing refrigerator of a membrane separation concentrating solution, is to realize effects of saving energy, environmental protection, production cost reduction, daily operation expense reduction, easy maintaining and safety. The refrigerator includes an evaporator (1), an absorber (2), an air extractor (3), an evaporator pump (4), an absorbor reflux pump (5), a setting membrane separating and filtering device (6), the membrane separating and filtering device is provided with a liquid inlet, a liquid outlet and a water outlet which are connected with an absorbor dilute solution outlet, an absorbor concentrated solution inlet and an evaporator water inlet respectively. The invention is suitable for central air-condition systems in hotels, emporiums and office buildings.

Description

technical field [0001] The invention relates to a refrigeration machine, in particular to a lithium bromide absorption refrigerator. Background technique [0002] Lithium bromide absorption chillers have the advantages of not needing to consume a lot of electricity, and are widely used in central air-conditioning systems in hotels, shopping malls, and office buildings. But the weak point of existing lithium bromide absorption refrigerating machine is: what concentrated lithium bromide dilute solution used is distillation, and this will consume a large amount of heat energy, in order to obtain these heat energy, often will burn a large amount of coal or oil or gas; At the same time, it is necessary to install bulky generators and condensers, as well as expensive boiler equipment and boiler rooms or direct combustion devices with complex structures; due to the increase in cooling water, the capacity of cooling water pumps and cooling tower...
