20130291573 | METHOD AND APPARATUS FOR DRYING COMPRESSED GASES - A method maintains, in a compressed gas dryer, working through condensation of moisture contained in the air and with dryer thermal load demands, an operation that keeps the temperature of the evaporator, near the outflow of the compressed air, in range between a value sufficiently high to avoid freezing the moisture in the compressed air and a value sufficiently low to avoid compromising the effect of moisture condensation generated by the decreased temperature. This objective is achieved with a compressor by-pass conduit on which is mounted a selectively controllable adjusting valve. The operation includes: measurement of the evaporation temperature (Tev), and verification the temperature is higher than a preset value (Set_Tev); starting the compressor; opening the valve for a preset time, and then closing it; verification that the temperature is higher than a preset value; if the time elapsed is longer than a predetermined time, then the valve is opened. | 11-07-2013 |
20130319021 | METHOD OF CONTROLLING AIRFLOW THROUGH A WATER RECOVERY DEVICE - A system and method recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. A foam media absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to dynamically control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection. | 12-05-2013 |
