Abstract: An evaporative cooler which includes a sealed loop of conduit with a first portion in a space to be cooled and a second portion in a space where heat is rejected, a volume of working fluid, and a fan inside the conduit loop. The fan forces air over the working fluid to accelerate its evaporation, which requires heat. Evaporation creates vapor-enriched air which carries heat and is forced by the fan to the second portion. Within the second portion, the vapor-enriched air rejects the absorbed heat before being forced back to the first portion. In certain cases, a portion of the working fluid in the vapor-enriched air condenses out and drains or is pumped back to the first portion. In certain uses, the cooler provides cooling to an area. In other uses, the cooler captures vaporized water, producing an impurity-free condensate for removal or use.

Abstract: A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.
