COMPACT ABSORPTION CHILLER AND SOLUTION FLOW SCHEME THEREFOR

摘要

An absorption chiller (10) includes a first shell (12) containing anevaporator (20) having an upper portion and a lowerportion and an absorber (18) vertically split into an upper high temperatureabsorber (22A) and a lower low temperature absorber(22B), a second shell (14) containing a condenser (30) and a low temperaturegenerator (32), and a third shell (16) containing a directfires high temperature generator (34). Weak solution is pumped in parallelfrom the absorber (18) to both a high temperature generator(34) and a low temperature generator (32) which is disposed vertically abovethe high temperature generator (34). Concentratedsolution flows from the low temperature generator (32) to the low temperatureabsorber (22B) as a result of the elevation differencebetween them, while it flows from the high tempeature generator (34) to thevertically elevated high temperature absorber (22A) asa result of the pressure difference between them.
