Carrier 16DF013-050 - Manual (Page 4)

The smaller shell above the evaporator/absorber assem-
bly contains the low-stage generator and condenser. In the
cooling cycle, about half of the diluted lithium bromide
solution is heated and reconcentrated in the low-stage
generator by high-temperature vapor from the high-stage gen-
erator. The water vapor released from the solution in this
process is condensed to liquid in the condenser section. This
vessel is not used in the heating cycle, although about half
of the diluted solution does flow through the generator.
This chiller also has: 2 solution heat exchangers to im-
prove operating economy; an external purge system to main-
tain machine vacuum by the continuous removal of noncon-
densables; 2 hermetic pumps to circulate the solution and
refrigerant; various operation, capacity, and safety devices
to provide automatic, reliable machine performance; and the
ability to manually switch between cooling and heating
operation.
