SUPER ABSORPTION

Direct-fired chiller / heaters

F. Condenser section

The refrigerant vapor from the low temperature generator is condensed on the cooling water heat transfer tubes of the condenser (see Figure 7). The cooling water from the absorber flows through the condenser and removes the heat of condensation from the refrigerant vapor from the low temperature

G. Refrigerant path and flow

In the high temperature generator, the heat source separates the refrigerant from the lithium bromide solution.

The lithium bromide solution follows line D to E of Graph 10.

Line D to H of Graph 10 follows the refrigerant path and illustrates the change of refrigerant vapor to liquid as it passes through the low temperature gen- erator. The refrigerant then flows to the condenser (line H to I) where addi- tional heat is removed. In the low temperature generator additional refriger- ant is released from the lithium bromide solution (line F to G); this released refrigerant travels to the condenser (line F to I) where it is condensed into a

generator section and is rejected to the cooling tower.

The condensed (liquid) refrigerant then flows to the evaporator where the cycle starts again.

liquid. Point I represents the combination of liquid refrigerant from both the low temperature generator and the condenser. The liquid refrigerant flows into the evaporator where it mixes with evaporator refrigerant and is pumped to the evaporator's dispersion trays (line I to J). The refrigerant is dispersed on the evaporator heat transfer tubes and vaporizes; the vapor is absorbed by the concentrated solution in the absorber causing the bromide solution to become diluted (line J to B). The diluted solution flows to the low temperature heat exchanger (line B to C) where the cycle is repeated.
