SUPER ABSORPTION

Heating cycle

In the absorption heating cycle (Figure 10), the unit is essentially acting as a	heat transfer tubes removes the sensible heat of the condensed refrigerant
boiler. Diluted solution is heated in the high temperature generator releasing	and transfers the heat to the hot water loop. The condensed refrigerant is
refrigerant vapor from the absorbent.	mixed with the intermediate solution creating diluted solution. The diluted
The refrigerant vapor flows to the absorber/evaporator and condenses on	solution is pumped back to the high temperature generator where the cycle
the heat transfer tubes of the evaporator. The water through the evaporator	is started again.
