Title: Open absorption cycle for combined dehumidification, water heating, and evaporative cooling

Abstract

An absorption cycle system, which permits water heating, dehumidifying, and/or evaporative cooling, includes a desorber, absorber, heat exchanger, and, optionally, an evaporator, is constructed to heat a process water that is plumbed through the absorber, heat exchanger, and condenser. In the absence or isolation of the evaporator, the system can dehumidify ambient air to the absorber. The water vapor released by evaporative cooling at the evaporator can be provided to the absorber in a controlled manner to simultaneously maintain a desired humidity while cooling the air ambient by the evaporator. The absorption cycle system can be housed within a single unit or can be compartmentalized.
