An atmospheric water generator (AWG) with a water cooling system is disclosed. In some embodiments, the AWG includes a cooling compartment defined by walls, designed to comprise a cooling medium and comprising a refrigerant coil. The storage tank for storing the water that are generated by the AWG shares at least a portion of a common wall with the cooling compartment. The refrigerant coil of the cooling compartment is in fluid communication with the refrigeration cycle and designed to be at least partially submerged in the cooling medium. In some embodiments, the stored water tank is submerged in the cooling compartment. Other embodiments are also disclosed.

A cold evaporation water purification system by through fractionated surfaces based on a physical phenomenon of liquids called adhesion principle. The liquid sticks to the contour of a solid surface, imitating its shape and thickness, this, by being rounded and thin, allows the thinning of the aqueous films, making them embrace the whole segment (contact surface) and in this way reducing enormously the energy used to carry out evaporation. The thin aqueous film will be efficiently distributed in 360 degrees of a fractionated system that is also in rotation, causing cold evaporation to be much more efficient with respect to commonly used methods. The cold evaporation water purification system by through fractionated surfaces comprises an evaporation mesh, a rotating element, a plastic tub, an air flow turbine and a condensing element.

A distillation and desalination system can include a refrigeration unit and a vacuum source positioned in the refrigeration unit. The vacuum source can include a first chamber defining a first chamber volume, a second chamber defining a second chamber volume, a flexible diaphragm dividing the first chamber and the second chamber; and a check valve permitting gas transport into and out of the first chamber, the check valve comprising an inlet and an outlet. The system can also include a distillation unit having a distillation chamber, a saline liquid in the distillation chamber, and a headspace above the saline liquid, the headspace comprising a gas. The inlet of the check valve can be fluidically coupled to the headspace of the distillation unit.

According to an embodiment, a multi-cooling type cold trap according to the present disclosure includes a main body unit in which an inflow space having a material to be condensed flown therein is formed, a circulation unit which is disposed in the inflow space of the main body unit and circulates cooling water for condensing the material to be condensed, and a supply unit which supplies the cooling water to the circulation unit after lowering temperature of the cooling water in stages.

Xenon and/or krypton is separated from a liquid oxygen stream comprising oxygen and xenon and/or krypton in a process comprising providing at least a portion of the liquid oxygen stream as a reflux liquid to the top of a rare gas recovery column operated at a pressure of between 5 to 25 bara, vaporizing a reboiler liquid in the reboiling zone in the bottom of the rare gas recovery column to produce a mixture of a rising vapor and a xenon and/or krypton-enriched liquid stream; and contacting the rising vapor with the reflux liquid in at least one distillation zone of the column to effect stripping xenon and/or krypton from the rising vapor to the reflux liquid. The process provides a recovery of xenon of greater than 90% and a krypton recovery of 15% to 90%.

Method for collecting water vapor from air as liquid water. The method includes a refrigerant compressor circulating refrigerant through a controlled dimensioned condenser into a tubing loop. A portion of the tubing loop functions as a condenser. This tube conveys the pressurized refrigerant through an expansion valve. The refrigerant pressure and temperature decreases. Ambient water vapor collects on the exterior surface of the cooled section of tube now functioning as an evaporator. The water drops from the tube surface into a reservoir for use. The tube loop extends through a multiport control valve. The method includes a control valve that cyclically and sequentially directs the refrigerant pumped from the compressor into alternate ends of the tubing loop. The cycles continually repeat. The cycles can be controlled by fluid temperature. The device can include a power supply and microprocessor controlling the generator and valves. The device may utilize a switch that detects water or ice deposits on the tube. The device can comprise a moveable frame supporting all above components.
