How does it work?

Heat from several sources (exhaust gas, engine hot water or burner) heats a lithium bromide (LiBr) solution, which releases water vapour. This vapour is condensed by the cooling water, then the water flows into the evaporator, under high vacuum: there it evaporates and cools the chilled water. The vapour is then absorbed again by the solution, which goes back to be heated, and the cycle starts over. Cooling is thus produced with heat, without a compressor.
