Abstract
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.

An atmospheric water generator (AWG) that includes:
- a cold coil for extraction of atmospheric water from air;
- 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;
- a source of water that is connected to an water chiller evaporator with a water chilling flow path on a first side of the water chiller evaporator that is isolated from and in thermal communication with a second side of the water chiller evaporator;
- a binary liquid-vapour mixture supply line from the bubble reactor connected through an evaporator pump to the second side of the water chiller evaporator for evaporation of the binary liquid-vapour mixture and thermal energy extraction from the water in the water chilling flow path;
- the water chilling flow path connected from the water chiller evaporator to the cold coil;
- and a binary liquid-vapour mixture return line from the second side of the water chiller evaporator connected to an absorber with a binary liquid-vapour mixture outlet connected back into the bubble reactor.
