Abstract

In certain embodiments an all vapor driven absorption heat pump is provided comprising a first heat pump generator comprising a falling film heat exchanger and configured to receive a high temperature vapor and a dilute working medium and to evaporate heat transport material from the dilute working medium; optionally, a second heat pump generator comprising a second falling film heat exchanger configured to receive concentrated working medium and output vapor produced in the first heat pump and to further evaporate the working medium and provide a mid-temperature vapor output and a concentrated working medium; and a heat pump absorber configured to receive a low temperature vapor and the concentrated working medium from the first heat pump generator when the second heat pump generator is absent and to receive said concentrated working medium from the second heat pump generator when the second heat pump generator is present.

Description

[0001] Related Application Cross Reference [0002] This application claims priority and benefit to USSN 61 / 609106, filed March 9, 2012, the entire contents of USSN 61 / 609106 being incorporated herein by reference in all respects. technical field [0003] The invention relates to absorption heat pumps, desalination processes and vapor recompression. In particular, in certain embodiments, novel high-efficiency steam-driven absorption heat pumps and absorption heat exchangers and applications thereof are provided. Background technique [0004] In heat engine applications a large amount of low temperature heat is generated and usually must be dissipated to the environment by wet cooling or dry cooling. Typically, heat engines utilize the expansion of high temperature and high pressure steam (eg, water vapour / steam) to generate power, so waste heat is typically provided in the form of low temperature steam containing latent heat. In a wet cooling process, the condenser utiliz...
