A refrigerator includes a storage compartment having a front opening and an air sanitation device mounted on a top wall of the storage compartment. The air sanitation device includes: a housing, an air channel located in the housing, a fan, and an air detection device and/or an air purification device located in the air channel. The housing includes a front wall facing the front opening, a rear wall, an upper wall, a lower wall, and a pair of side walls. The air channel includes an air inlet and an air outlet. The fan is configured to force air to enter the air channel from the air inlet, and then be discharged out from the air outlet. The air inlet is located on at least one of the side walls, and the air outlet is located on the rear wall.

A system, apparatus, and method are provided for extracting water from ambient air. An inlet is provided to receive ambient air into the system, a cooling chamber where extraction of water occurs, and a reservoir for collecting extracted water. The apparatus extracts water by pre-cooling ambient air and then further reducing the temperature of the air in the cooling chamber until water particles condense on surfaces in the cooling chamber. The extracted water is then transferred to the reservoir where it can be collected until a distribution module removes the water from the system. The system may further comprise means for sanitizing the collected water, rendering it safe for human use along with a controlling module and insulated and conductive components configured to reduce energy loss, optimize water recovery, and increase water yield.

A sensor cooling and cleaning system for a vehicle includes an inlet that is coupled to an air intake of a vehicle body and positioned to receive ram air when the vehicle is in forward motion. The system includes a passive air conditioning device that is configured to remove moisture from the ram air received through the inlet to produce conditioned air. The system also includes an outlet that is positioned adjacent to and upstream of sensor to direct the conditioned air from the passive air conditioning device toward a stagnation point that is located upstream of the sensor, during the forward motion of the vehicle.

A system for dehydrating raw produce without introducing excess heat to the produce, including a first chamber for holding warm, moist air, a second chamber connected in fluidic communication with the first chamber for cooling and drying warm, moist air received from the first chamber, and a filter operationally connected between the first and second chambers for removing suspended particulates from warm, moist air flowing therethrough with a drain operationally connected to the second chamber for removing water therefrom. A third chamber is connected in fluidic communication with the second chamber for receiving cool, dry air therefrom and for receiving raw produce for drying, and a wind current generator operationally connected to the second chamber to urge cool, dry air therefrom and into the third chamber.

An air drying unit for compressed air systems is provided. The air drying unit has a precooler/reheater, a main cooler and a moisture separator. Incoming air is cooled to cause moisture within the compressed air to condense, which is then separated to dry the compressed air. The precooler/reheater, main cooler and moisture separator are designed as an integral unit that does not require pipes to connect the components together. Instead, compressed air flows through the sealed unit through passages therein between the precooler/reheater, main cooler and moisture separator.

A system of generating an aerosol, by: (a) placing a liquid into a liquid chamber in an ultrasonic nebulization system having a cylindrical aerosol production chamber received within a cylindrical master chamber, and having top and bottom ultrasonic transducers; (b) passing air up through the aerosol production chamber; and (c) producing acoustic standing waves above the surface of the liquid with the top and bottom ultrasonic transducers, thereby generating an aerosol of the liquid by action of the standing waves.

An automated system for the separation of vapor and liquid from a gas and liquid combination entering a separation vessel. A programmable logic control unit module controls a valve and is programmed for periodic release of separated liquid collected within the vessel upon achieving various conditions within the vessel or upon expiration of a pre-established time interval, with separated liquid delivered via an outlet port through a valve controlled by the programmable logic control unit to a storage tank.

Various methods and systems are provided for removing liquid from a sample containing both liquid component and gaseous component. In particular, the liquid component may be separated from the sample by flowing the gaseous component of the sample from a lower chamber to an upper chamber through a membrane. The liquid portion of the sample may be drain from the lower chamber via a drainage channel within the bottom wall of the lower chamber. The liquid portion of the sample flows horizontally outward in the drainage channel through capillary action induced by a capillary part positioned within the drainage channel.
