Abstract

See full text

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.
