Abstract
An absorption chiller includes a vertically split absorber section the upper portion of which is a high temperature absorber and the lower portion of which is a low temperature absorber. Weak solution is pumped in parallel from the absorber to both a low temperature generator and a high temperature generator. The low temperature generator is disposed vertically above the high temperature generator. Concentrated solution flows, in parallel, from the low temperature generator to the low temperature absorber and from the high temperature generator to the high temperature absorber. The flow of concentrated solution from the low temperature generator to the low temperature absorber is as a result of the elevation of the low temperature generator above the low temperature absorber while the flow of concentrated solution from the high temperature generator to the vertically elevated high temperature absorber is as a result of the pressure differential between the high temperature generator and the high temperature absorber.
