  • Patent number: 11179669
    Abstract: A dehumidification air conditioner reduces carbon dioxide levels in a low humidity workroom. Cooling dehumidification is performed on outdoor air in a pre-air-cooler to produce pre-cooled air, which is branched such that a first part passes through a processing zone of an adsorption rotor which can remove carbon dioxide and humidity simultaneously, and a second part passes through a purge zone of the adsorption rotor. Air which passed through the processing zone is supplied to a low humidity workroom. Air which passed though the purge zone of the adsorption rotor is mixed with outdoor air and then heated with a reproduction heater to produce heated air. The heated air is sent to a reproduction zone of the adsorption rotor, to simultaneously remove carbon dioxide and humidity from the adsorption rotor and produce an exhaust stream which exhausted out of the device.

  • 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: 10201776
    Abstract: An absorption type carbon dioxide removal/concentration apparatus has a honeycomb rotor which holds an amine support solid absorbent. The honeycomb rotor is divided into at least a processing zone and a reproduction zone. An enthalpy (temperature and humidity) adjustment device is provided for the air for reproduction and/or the air to be processed. The apparatus can control the carbon dioxide absorbing performance and the concentration performance by passing processing and reproduction air through the corresponding zones. The absorption type carbon dioxide removal/concentration apparatus can remove or condense carbon dioxide, can secure high recovery efficiency and can prevent a thermal deterioration of the amine absorbent to extend the life-span of the apparatus.

  • Patent number: 9908083
    Abstract: An absorption-type carbon dioxide removal/condensing apparatus is removes or condenses carbon dioxide so that the apparatus secures high recovery efficiency. The apparatus has a honeycomb rotor holding a carbon dioxide absorbent, which is divided into at least a processing zone and a reproduction zone. After anyone of reproduction air for heating and a processing air is humidified by a humidifying device, both airs are ventilated into the zones, respectively. Thereby, the apparatus can improve absorption performance and density performance. If the honeycomb rotor is further divided into at least first and second processing zones, an air to be processed is humidified by a humidifier to ventilate into the first processing zone, and then a portion or all of the processing air which passed through the first procession zone is passed through the second procession zone (second pass).
