An air purifying apparatus includes a humidity controller and an intake cooling separator including one or more shafts and an outer wall. The intake cooling separator generates airflow to obtain the humidity-controlled air. The intake cooling separator swirls the obtained air around a first shaft included in the one or more shafts, thereby generating a pressure difference between air included in the obtained air and around the first shaft and air included in the obtained air and around the outer wall, and the pressure difference cools at least a part of the obtained air, and the pressure difference cools at least a part of the obtained air. The intake cooling separator performs centrifugal separation of water droplets generated from the cooled air. The one or more shafts are rotated to generate the airflow, to cause the swirl, and to perform the centrifugal separation.

The device for evaporating volatile substances comprises a casing (1) provided with a housing for the placement of a refill (2) containing the volatile substances, and is characterised in that said casing (1) comprises a surface (3) provided with at least one coupling element (5) in order to couple an additional element (4), said additional element comprising a frame (7) and a releasable sheet (8).

It provides an evaporation device that can be easily customised.

Provided is an aerosol generating device which is capable of stopping aerosol generation at an appropriate timing. This aerosol generating device includes a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a circuitry which controls the power supplied from the power source on the basis of the measurement value. The circuitry controls to increase a power supply amount per unit time in response to a first condition that the measured value is equal to or larger than a first threshold being satisfied, and to decrease the power supply amount per unit time in response to a second condition that the measured value is less than a second threshold greater than the first threshold and a third condition which is different from the first condition and the second condition being satisfied.

A canister assembly for use in an exhaust gas aftertreatment device comprises a cylindrical shell defining a cylindrical axis, a radial direction, and a circumferential direction, a top end and a bottom end. A flow tube is inserted into the top end of the cylindrical shell and terminates short of the bottom end of the cylindrical shell, defining an exit of the flow tube. A mixing bowl member including a symmetrical annular shape about the cylindrical axis and defining a mixing bowl pocket is attached at the bottom end of the cylindrical shell.

Condensing apparatuses and their use in various heat and mass exchange systems are generally described. The condensing apparatuses, such as bubble column condensers, may employ a heat exchanger positioned external to the condensing vessel to remove heat from a bubble column condenser outlet stream to produce a heat exchanger outlet stream. In certain cases, the condensing apparatus may also include a cooling device positioned external to the vessel configured and positioned to remove heat from the heat exchanger outlet stream to produce a cooling device outlet stream. The condensing apparatus may be configured to include various internal features, such as a vapor distribution region and/or a plurality of liquid flow control weirs and/or chambers within the apparatus having an aspect ratio of at least 1.5. A condensing apparatus may be coupled with a humidifier to form part of a desalination system, in certain cases.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.
