Abstract: Disinfection device against viruses, bacteria and other microorganisms using ozone without contaminating the environment with ozone or users cross contamination. Disinfection is obtained by inserting an organ (e.g. hands) into a chamber containing a predetermined ozone concentration for a predetermined time. A suction duct surrounds the chamber. Ambient air mixed with overflow ozone from the chamber is fed through the suction duct into an ozone filter, then to an air outlet so the discharged air meets FDA regulation. The top of the chamber can be permanently open for inserting hands without ozone being discharged to the environment.

Abstract: A heat exchanger comprises a stack of sets of fins and tubes attached to or encompassed by embossed plates comprising a void. In some embodiments, the fins overlap the void having a peripheral margin of the fin attached to the peripheral margin around the void. In some embodiments, the fins comprise through fluid apertures allowing lateral fluid flow. In some embodiments, the plates comprise lateral peripheral protrusions enabling selective sealing of gaps between adjacent stacked plates by unselective application of heat or adhesive to a face of the heat exchanger. In some embodiments, the plates comprise uniformizing protrusions in a fluid inlet and/or outlet zone that reduce the amount of non-uniform fluid mass flow between different channel protrusions of heat exchanging zones of the set. Also disclosed are methods for assembly and selective sealing of the heat exchanger and an apparatus comprising the same.

Abstract: A system of managing water production in a vehicle. The system comprises a water conducting element set to receive and conduct water generated as a product of an operation of a vehicle air conditioner of the vehicle to a water container, a gauge that measures the amount of water in the water container, and a manager that receives the measurement and instructs the operation accordingly.

Abstract: A vehicle having an integrated air conditioning system and beverage cooling system comprising apparatus for compressing a refrigerant fluid, first apparatus for receiving and evaporating the compressed refrigerant fluid, apparatus associated with the air conditioning system for circulating air across the first apparatus for receiving and evaporating, and second apparatus in heat conductive engagement with a beverage container for receiving and evaporating the compressed refrigerant fluid.
