    Abstract: An aircraft air conditioning system including a process air line having a first end connected to a process air source to allow a flow of process air therethrough. A ram air channel of the air conditioning system allows ambient air flow therethrough. A heat exchanger unit is disposed in the process air line and arranged within the ram air channel to thermally couple process air flowing through the process air line to ambient air flowing through the ram air channel. A water extractor disposed in the process air line downstream of the heat exchanger unit extracts water from the process air. A water supply system supplies extracted water into the ram air channel. The water supply system has a control arrangement to control a fluid connection between the water extractor and the ram air channel in dependence on an operating state of the aircraft air conditioning system.

  • Patent number: 8943844
    Abstract: An air conditioning system includes a dehumidifier, a regenerator, and a refrigeration system. The dehumidifier removes water from a first airflow using a liquid desiccant. The regenerator transfers water from the dilute desiccant into a second airflow. The refrigeration system can be selectively used to provide heat to the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. An external heat source can also be used to heat the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. The refrigeration system and the external heat source can each be used separately to heat the desiccant, or the desiccant can be heated by both heat sources simultaneously.

  • Patent number: 7685829
    Abstract: Process and device for generating a current of humid air having a defined relative humidity comprising the steps of generating a current of air in a tubing arrangement, generating hot water vapor, introducing the water vapor into the air current to generate flowing hot humid air, passing the hot humid air through a water separator while lowering the temperature of the humid air below the dew point temperature to generate saturated humid air having a defined temperature, heating the humid air coming from the water separator above the defined temperature to achieve a defined relative humidity, and discharging the humid air from the tubing arrangement as a current of humid air having a relative humidity of not less than 80%.

  • Patent number: 7654307
    Abstract: An automotive air conditioning system is disclosed comprising an evaporative cooler in series with the conventional vapor compression system. The evaporative cooler comprises an array of dry channels and a contiguous array of wet channels. The primary air stream to be conditioned by the evaporator of the conventional air conditioning system is preconditioned by the evaporative cooler by lowering its dry bulb temperature without changing its absolute humidity. An evaporator core is supported downstream of the evaporative cooler for receiving the primary air from the dry channels and thereby produces liquid condensate. The system is distinguished by conducting the liquid condensate from the evaporator core to the wicking tank for use in the wet channels of the evaporative cooler.

  • Publication number: 20090211298
    Abstract: The invention relates to an apparatus for creating an air-conditioned atmosphere in a transportation container (14), having a compressor (3) for generating compressed air, a cooling device (5) for cooling the compressed air and a gas-separation diaphragm (10), which is connected downstream of the compressor (3) and the cooling device (5), for producing a nitrogen-rich gas stream, and a wetting diaphragm (12), with the apparatus permitting controlled wetting of the nitrogen-rich gas stream. The invention also relates to a method for creating an air-conditioned atmosphere in a storage or transportation container, in which method compressed air is generated by means of a compressor, the compressed air is then cooled using a cooling device and a nitrogen-rich gas stream is produced from the compressed air for the purpose of conduction into the transportation container by means of a gas-separation diaphragm.

  • Patent number: 7155318
    Abstract: In a method of operating an air conditioning unit to reduce moisture varying operations, psychrometric chart data is accessed. In addition, a constraint is set on the relationship between the temperature of air supplied by the air conditioning unit and the relative humidity of the air supplied based upon information contained in the psychrometric chart data. The air conditioning unit is controlled based upon the constraint to thereby reduce moisture varying operations of the air conditioning unit.
