As shown in Fig. 1, a single lithium bromide absorption refrigeration unit has a rectangular parallelepiped structure and is internally provided with heat exchange components such as a regenerator, an evaporator, an absorber, and a condenser. The basic working principle is: using lithium bromide solution + pure water as the working medium pair, pure water as the refrigerant water, lithium bromide solution as the absorption liquid, relying on pure water to evaporate and absorb heat in a high vacuum environment to achieve refrigeration. The refrigerant absorbs heat and evaporates into a vapor. The refrigerant vapor no longer has a phase change endothermic capacity and, therefore, is absorbed by the lithium bromide solution and then regenerated by heating with the lithium bromide solution. The refrigerant water is evaporated to heat and becomes a refrigerant vapor. The refrigerant vapor is condensed and returned to the liquid state, and again absorbs heat and evaporates. The refrigerant water absorbs heat and absorbs - absorption - regeneration - condensation - and then absorbs heat and evaporates, so that the source continuously performs the refrigeration cycle. The refrigeration unit uses cold water, cooling water and cold water piping systems to circulate and exchange cold water, hot water and cooling water between the evaporator, regenerator, absorber and condenser components to complete the refrigeration process and realize the The outside world gains energy, releases heat to the outside world, and supplies cold to the outside world.
