  • Patent number: 9243810
    Abstract: A desiccant air conditioning system treats an air stream entering a building space. The system includes a conditioner having multiple structures arranged in a substantially vertical orientation, each having at least one surface across which a liquid desiccant can flow. The air stream flows through or between the structures such that the liquid desiccant dehumidifies the air stream in a warm weather operation mode and humidifies the air stream in a cold weather operation mode. Each structure further includes a desiccant collector at a lower end of the at least one surface for collecting liquid desiccant that has flowed across the at least one surface of the structure. A regenerator receives liquid desiccant from the desiccant collectors in the conditioner and causes the liquid desiccant to desorb water in the warm weather operation mode and to absorb water in the cold weather operation mode.

  • Patent number: 8557029
    Abstract: Methods and systems for regenerating a purification bed take advantage of inert gas pressure, such as, for example, supplied by a pipeline. The inert gas (102) is provided at a first pressure and combined with a recycle composition (116) from the vessel (110, 110a) containing the material being regenerated. These streams form a regeneration fluid composition (114) at a second pressure less than the inert gas pressure, which is then routed to the vessel to regenerate the purification bed. A jet compressor (108) may be used for the combining of the inert gas and recycle streams. The recycled composition allows reduction in inert gas usage, while a portion is flared or otherwise disposed of.

  • Patent number: 8545609
    Abstract: The Microwave System and method of reactivation is designed to provide an indirect, safe and energy efficient source of heat and temperature rise required in the reactivation section of the desiccant unit for the release into atmosphere of the water vapors which are accumulated in the desiccant rotor. This microwave reactivation system and method is based on heat transfer produced from a heated fluid which is pumped through a closed loop coil assembly. This closed loop coil assembly is located and runs through both the isolated heating chamber of the microwave section and the reactivation / regeneration section in the dehumidification system. The airstream passing through the reactivation intake section comes in contact with the coil assembly and is heated to the desired temperature prior to reaching the desiccant rotor.

  • Patent number: 8500882
    Abstract: There is provided an air purifier having a dehumidification function, including: a body case having an inner space; a blower part installed in the inner space of the body case and drawing outside air from both sides of the body case through a single blower fan; an air purifying part purifying air drawn from one side of the body case; and a dehumidifying part removing moisture from air drawn from the other side of the body case by a dehumidifying rotor. Through the blower part drawing the air from both sides of the body case, the air purifier purifies the air drawn from one side of the body case and dehumidifies the air drawn from the other side of the body case. Accordingly, a drop in an airflow amount caused by concurrently performing the dehumidification and the purification may be alleviated, so improved dehumidification and purification effects are achieved.

  • Patent number: 8500886
    Abstract: Exhaust gas after coal or oil burning has moisture, which hinders carbon dioxide adsorption. It is necessary to completely remove this moisture with the minimum use of energy. The exhaust gas from the burning apparatus is first lowered of its temperature by passing through an total heat exchanger rotor, and the resultant gas which has low temperature and humidity is sent to a carbon dioxide adsorption rotor, thereby removing carbon dioxide from the gas, which is then sent through the total heat exchanger rotor with the resultant desorption of moisture adsorbed there and is exhausted to outside atmosphere, while the carbon dioxide adsorption rotor is desorbed of its carbon dioxide using water vapor, with the resultant very humid carbon dioxide to be sent to a processing system such as for underground burial.
