How does the absorption chiller operates by solar energy? detailed drawings and explanation of absorption chiller is dependent primarily on solar energy with the aid of electricity is necessary
As the refrigerant absorbs heat from the heat source evaporates in a volume which is discharged through a spray highly concentrated solution of a chemical that absorbs the refrigerant (A common combination is refrigerant water and lithium bromide absorbent); The absorbing solution becomes diluted and requires regeneration: it is pumped to a heat exchanger where it is summed up by leaving a solution closer to the liquid refrigerant and gaseous . absorbent must be cooled and condensed refrigerant: This is the part of the cycle heat sink. The solution is cooled and condensed refrigerant is then recycled into the absorption chamber.
Solar provides the heat can be used in the regeneration cycle.
Practical considerations include the fact that the chemical absorption can be expected to be highly exothermic and the heat absorption must be dissipated power is needed to run the pumps that move different fluids, chemical considerations such as LiBr * H20 is very corrosive all the ammonia is toxic, explosive, etc.
