Analyses and compares the efficiency, environmental pollution and economic accounting of Libr-absorption chillers, points out to use Libr-absorption chillers widely is impracticable.

In this paper, the way of providing cold energy and the existing Problem were discussed, the specification and annual operation cost of the single-action on liBr-Refrigeratory were thoroughly studied.

Based on the study of the characteristics of heat and mass transfer of absorption, a numerical model to simulate the process of absorption of LiBr solution is established.
