All fins heat-exchanger combined lithium bromide absorption refrigerator

Abstract

The present invention relates to a lithium bromide absorption type refrigeration equipment formed from all plate fin type thermal mass exchange. It mainly includes absorber, generator, evaporator, condenser and solution exchanger, etc. It is characterized by that the above-mentioned every component is formed from reasonably remoulded plate fin type thermal mass exchanger, and very componnet liquid can be effectively cooled or heated, so that its heat transfer and mass transfer capacity can be greatly raised.

Description

Technical field [0001] The invention relates to a lithium bromide absorption refrigeration device composed of a full-plate-fin heat and mass exchanger, which belongs to the industrial field of refrigeration and air conditioning. Background technique [0002] At present, the parts of lithium bromide absorption refrigeration equipment in the refrigeration and air-conditioning industries generally use shell-and-tube heat exchangers. Equipment with this structure has problems such as heat transfer, low mass transfer coefficient, poor compactness, and the smaller the relative cost, resulting in lithium bromide. The whole absorption refrigeration device is large in size, heavy in weight, high in initial investment, and unfavorable for popularization and application. Take the two most critical components in the lithium bromide absorption refrigeration device-absorber and generator as an example. Conventional absorbers and more advanced generators are in the form of horizontal tube and s...
