The invention relates to an atmospheric water generator that includes an absorption heat transformer (AHT) designed as a heat pump that is able to extract heat even from waste heat sources at or below ambient temperatures, with an evaporator working at a favourable design temperature (preferably between 2° C. and 15° C.) for chilled water supply to a cold coil that extracts atmospheric water from ambient air. The AHT employs a pseudo-isobaric temperature glide bubble reactor that contains a suitable binary liquid-vapour mixture in a density separation distillation environment, powered by a vapour absorption process.
