1. Strong solution of ammonia is formed in the absorber, dissolving fairly dry Ammonia Vapour in cold water.
The weak solution containing very little ammonia in sprayed is absorber, absorbs ammonia from the evaporator, lower the pressure in absorber & as a result more ammonia Vapour is drawn from the evaporator.
2. Pump.
3. Heat exchanger.
4. Heater/generator.
5. Oil separator.
6. Ammonia gas expelled from the strong solution in the generator & passes on the condenser.
7. Throttle Valve lowers the pressure.
