  • Patent number: 10730008
    Abstract: A device for the dehumidification of air in a processing space of a dishwasher is connected in an air-conducting manner to the processing space of the electric appliance. The device includes carbon-based fibres, which are designed as a fibre unit. The fibre unit is arranged between the processing space or an air duct connected thereto and at least one dehumidification chamber of the device. The carbon-based fibres absorb moisture from the air of the processing space, which they then release again in the dehumidification chamber. During this process, the carbon-based fibres are moved backwards and forwards between the processing space or air duct and the dehumidification chamber, preferably by slow rotation on a support.

  • Patent number: 10702825
    Abstract: Outside air is cooled and dehumidified by a pre-cooler to pass through an adsorption zone of a carbon dioxide adsorbing rotor, producing air having a low carbon dioxide concentration which is cooled by an intercooler. The air that has passed through the intercooler is passed through an adsorption zone of a moisture adsorption rotor and then supplied to a low humidity working chamber. Return air from the low humidity working chamber may be mixed with the air leaving the pre-cooler. A part of the air which passed through the intercooler is branched to pass through a purge zone of the moisture adsorption rotor before being sent to a regeneration zone of the humidity adsorption rotor. Air that passed through the regeneration zone of the humidity adsorption rotor is mixed with outside air and then passed through a regeneration zone of the carbon dioxide adsorption rotor before being exhausted.

  • Patent number: 10695711
    Abstract: Adsorbers have many purposes in chemical, gas-processing, and petrochemical plants. Adsorbers may be used to remove components from gas streams. Adsorbers may be subjected to various issues, including but not limited to moisture breakthrough, spent catalyst, too high or too low pressure drop, over or under heating, over or under cooling, too high or too low flow rates, which can affect their performance or result in a shutdown of the adsorbers. Monitoring the adsorbers and the processes using adsorbers may be performed to determine if the adsorbent bed is reaching saturation, other problems are occurring, or if equipment failures are imminent. Monitoring also helps to predict behavior or problems in different adsorbers used in the same plant or in other plants and/or processes.
