20090095012 | Double-effect adsorption refrigeration device - The present invention relates to an adsorption chiller using double-effect cycle utilizing middle driving heat source of 100-150 degree centigrade. The cycle consists of two cycles such as high temperature cycle (HTC) and low temperature cycle (LTC). Zeolite-water system and silica gel-water system are used as adsorbent-adsorbate pairs of HTC and LTC respectively. Waste heat of zeolite generated at during adsorption period of the zeolite is re-used for pre-heating and desorbing the silica gel. | 04-16-2009 |
20100258426 | APPARATUS AND METHOD FOR DESALINATION - A water desalination system includes an evaporator for evaporating saline water to produce water vapor and an adsorption means in selective vapor communication with the evaporator for reversibly adsorbing the water vapor from the evaporator. The adsorption means is in selective vapor communication with a condenser, and desorbing means for desorbing the adsorbed water vapor from the adsorption means for collection by the condenser. The condenser is adapted to condense the water vapor to desalinated water. | 10-14-2010 |

20150159923 | ADSORPTION REFRIGERATOR - Provided is an adsorption refrigerator that achieves high cooling capacity while reducing the volume the device as a whole occupies. The adsorption refrigerator according to the present embodiment has a configuration in which only one adsorption reactor is positioned directly above a first lower-layer adsorption reactor and a second lower-layer adsorption reactor. In addition, the adsorption refrigerator according to the present embodiment performs sequence control in which one of the first lower-layer adsorption reactor and the second lower-layer adsorption reactor keeps performing an adsorption process, whereas the other one changes processes of preheating, desorption, precooling, and adsorption. | 06-11-2015 |
