COMPACT ABSORPTION CHILLER AND SOLUTION FLOW SCHEME THEREFOR

摘要

The absorbing chiller 10 according to the present invention comprises an evaporator 20 having an upper portion and a lower portion, and an absorber 18 vertically split into the upper high temperature absorber 22A and the lower low temperature absorber 22B. A first shell 12, a second shell 14 having a condenser 30 and a low temperature generator 32, and a third shell having a direct heated high temperature generator 34. Dilute solution is pumped into both the high temperature generator 34 and the low temperature generator 32 which is disposed vertically above this high temperature generator 34 in parallel from the absorber 18. From the low temperature generator 32 to the low temperature absorber 22B, due to their altitude difference, the condensed solution flows, while from the high temperature generator 34 to the vertically elevated high temperature absorber 22A, the pressure difference between them Due to this, the condensed solution flows.
