Abstract: Absorbers for a lithium bromide absorption machine are described. These systems may include a storage tank; a plurality of sprinklers, situated inside the storage tank, and adapted to receive a hot and concentrated lithium bromide solution, and to project the hot and concentrated solution inside the storage tank where the hot and concentrated solution is diluted to produced a diluted solution; a feed pump adapted to export the diluted solution from the absorber; a heat exchanger, positioned outside the storage tank and configured to cool the diluted solution; and a recirculation pump, configured to cause the diluted solution to be communicated from the storage tank to the heat exchanger, and to be returned from the heat exchanger to the plurality of sprinklers in a continuous recirculation process.
