A direct contact condensing heat-exchanger is provided with a water heat transfer medium in which combustion product gases are dispersed in finely divided bubble form against a relatively low hydrostatic pressure differential for efficient sensible heat and latent heat recovery purposes. In one actual application, a warm-air furnace system having a burner that produces combustion product gases as a heat source is provided with the novel direct contact condensing heat-exchanger as a seondary heat-exchanger that advantageously recovers both sensible heat and latent heat from the combustion product gases.

Dispersed bubble condensation

A absorption refrigeration system having cooling and heating modes of operation functions with a double-effect or 'split' refrigeration cycle having approximately the same refrigerant concentration span in each cycle loop. The system includes a novel direct expansion combined evaporator and absorber assembly with improved heat transfer characteristics and with interchangeable liquid flows accomplished through actuation of a conventional reversing valve. Also, the system is provided with improved recuperative heat exchangers to further increase system energy conversion efficiencies.
