A solar-powered system including a chamber that is bordered by an evaporation layer and a condensation layer; and a photothermal layer located over the evaporation layer so that sun rays incident on the photothermal layer are transformed into heat and the heat is supplied to the evaporation layer for evaporating water. The sun rays incident on the photothermal layer do not pass through the condensation layer prior to arriving at the photothermal layer.

Combined apparatus (1) for the synthesis of urea from ammonia and carbon dioxide, comprising an internal wall (3) which delimits two coaxial zones (4) inside the apparatus, operating respectively as reaction (4) and condensation (5) zones, and optionally also comprising a stripping zone and/or a scrubber integrated in the same apparatus.

A system for recovering water from air includes a skirt supported by legs and at least one interior wall suspended from the skirt. At least one exterior wall extends from an accumulator and is spaced apart from and substantially parallel to the at least one interior wall, thereby defining a flow channel between the at least one interior wall and the at least one exterior wall. At least one thermoelectric cooler (TEC) is connectable to an electrical power source for transferring heat from a cool side of the TEC to a warm side of the TEC, the cool side being positioned on the at least one interior wall, not in the flow channel, for cooling the at least one interior wall, the at least one interior wall defining a condensing surface proximate the at least one TEC.

A condenser system includes a collapsible container bag bounding a compartment and having an upper end and an opposing lower end, the container bag being formed of a polymeric film and being adapted to hold a fluid. A condenser bag is formed of a polymeric film and bounds a channel that extends between a first end and an opposing second end, the first end of the condenser bag being fluid coupled with the upper end of the container bag. A tubular transfer line has a first end coupled with the condenser bag at a first location so as to communicate with the channel and an opposing second end coupled with the condenser bag at a second location located between the container bag and the first location so as to communicate with the channel.

The present invention provides a heat exchange device featuring gas-liquid separation, comprising an evaporator unit and a condenser unit. The condenser unit comprises a central main guide tube, a plurality of condensation tubes connected to the two lateral sides of the central main guide tube, and a heat dissipation fin assembly provided on a periphery of each condensation tube. The central main guide tube comprises a gaseous-phase confluence chamber and a liquid-phase confluence chamber. The gaseous-phase confluence chamber is provided in an upper portion of the central main guide tube and communicates with the gas outlet through a gaseous-phase connection tube, and the liquid-phase confluence chamber is provided in a lower portion of the central main guide tube and communicates with the evaporation chamber through a liquid-phase connection tube. Each condensation tube comprises a first communicating section in communication with the gaseous-phase confluence chamber, a bent section bent downward from the first communicating section, and a second communicating section connecting the bent section to the liquid-phase confluence chamber.

A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.

An apparatus, system, and method for the extraction of water molecules from the air includes a combination of electrical mechanisms and materials engineering. With the help of hydrophobic and hydrophilic materials on an array of thermally conductive and electrically insulated materials, the extraction of water from the air is significantly increased. A combination of hydrophobic and hydrophilic materials and an electric field gradient moves the water molecules towards the collection system thus speeding up the water formation process. This also inhibits the re evaporation of the water droplets.

A condenser bag includes a body bounding a channel that extends between an inlet opening at a first end and an outlet opening at an opposing second end, the body being comprised of a polymeric film; an intake port bounding a port opening that extends therethrough, the intake port being directly physically secured to the first end of the body so that the port opening communicates with the channel of the body; and a tubular transfer line having a first end directly mechanically coupled with the body at a first location located between the inlet opening and the outlet opening so as to communicate with the channel and an opposing second end directly mechanically coupled to the intake port so as to communicate with the port opening thereof.
