Abstract
An absorption apparatus includes a generator with an integrated outlet box comprising a liquid sensing chamber and a solution outlet chamber. The sensing chamber has an opening into the generator, with the opening being sized according to the liquid surface area inside the sensing chamber. The outlet chamber has a larger opening into the generator to provide a more open flow path for solution to exit the generator through the outlet chamber. The more restricted opening in the sensing chamber allows a liquid level sensor therein to sense a relatively calm liquid level that tends to be at an average elevation of a boiling-disrupted liquid level in the generator. With the opening in the sensing chamber being appropriately sized, a variable speed pump, responsive to the liquid level sensor, controls the flow of solution into the generator to maintain a desired solution liquid level in the generator.
