20110048920 | Adsorbent - Adsorbate Desalination Unit and Method - An adsorption-desalination unit utilizing a silica gel—water working pair adsorbent—adsorbate having an economizing heat exchanger to pre-heat the incoming source seawater to be desalinated in an evaporator from about 8° C. to about 1° C. above the ambient seawater temperature. The economizing heat exchanger employs heat captured during the adsorption cycle to pre-heat incoming source seawater, thereby increasing the efficient use of energy in the unit. The heating fluid utilized to drive the desorption cycle is further utilized to heat the evaporator. A mist eliminator positioned intermediate the evaporator and the adsorbent heat exchanger chambers prevents non-vaporized water from entering the adsorbent heat exchanger chambers. | 03-03-2011 |
20110056219 | Utilization of Exhaust of Low Pressure Condensing Steam Turbine as Heat Input to Silica Gel-Water Working Pair Adsorption Chiller - A device and method for utilizing waste heat from the exhaust of a low pressure condensing steam turbine. An adsorption chiller is driven by heat recovered from the exhaust steam by incorporating a heat exchanger between the low pressure condensing steam turbine and the condenser of the steam turbine. The heat exchanger provides heated fluid which is then utilized as the hot water for the adsorption chiller. The adsorption chiller outputs chilled water which may be beneficially used for many purposes in the power plant. | 03-10-2011 |
20110132550 | Single Chamber Adsorption Concentrator - A single chamber adsorption concentrator unit is described that utilizes low grade heat to drive an adsorbent/adsorbent working pair to separate a solvent from a solute/solvent mixture. One preferred application of the device of the present invention is separating water from the salt brine produced by the aluminum smelting industry. The brine solution is introduced into a single chamber shell proximate the concentrator evaporator where the water in the brine can freely evaporate and the resulting water vapor freely flow without inhibition to be either absorbed into the adsorbent modules or condensed by the condenser. The free flow of water vapor is facilitated by continuous operation of the condenser and by maintaining the brine solution at a higher temperature than the cooling fluid driving the condenser. A mist eliminator with a wash down feature located intermediate to the evaporator and the silica gel is provided to collect contaminants that may be carried from the evaporator by the vigorous boiling. | 06-09-2011 |
20110240281 | Liquid-Based Cooling System For Data Centers Having Proportional Flow Control Device - A liquid-based cooling system provides a method of supplying a heated coolant fluid at a relatively constant temperature and pressure to one or more heat driven engines, such as adsorption chillers or heat pumps, by utilizing a proportional flow control device in association with each of a plurality of heat-producing electronic components to optimize the output of a plurality of liquid-cooled cold plates operatively mounted on such plurality of heat-producing electronic components. The proportional flow control devices may be electro-mechanical or solid state proportional control valves for water flow control. The proportion flow control devices are operatively connected to be actuated based upon the electrical signals typically generated to control the variable cooling fans of the electronic components. | 10-06-2011 |
20120012299 | Proportional Micro-Valve With Thermal Feedback - A proportional micro-valve for regulating the temperature of an electronic component comprising a cooling subsystem associated with each thermal zone of the electronic component, a cooling circuit carries cooling fluid to a heat exchanger associated with each thermal zone, the flow of which is controlled by a valve element, which is in turn controlled by a sensing circuit which reacts to the temperature of the underlying thermal zone to proportionally increase or decrease the rate of cooling fluid flowing through the heat exchanger based upon the temperature of the thermal zone. Cooling fluid substantially continuously flows through the sensing circuit, regardless of whether the valve element is open or closed. The sensing circuit provides feedback to a temperature-responsive mechanical amplifier for opening and closing the valve element. | 01-19-2012 |
20120042688 | Heat Driven Concentrator With Alternate Condensers - A device and method for concentrating contaminants in a solution comprising contaminated sorbate and clean sorbate wherein the contaminated sorbate freezes at a higher temperature than the clean sorbate. By maintaining the solution at a temperature between the freezing point of the contaminated sorbate and the freezing point of the clean sorbate, the clean sorbate may be evaporated off for processing through a sorbent/sorbate working pair adsorption/desorption cycle. Sensors in the adsorption chamber monitors for the presence of contaminated sorbate vapor. Sensors in the evaporator chamber monitor the temperature of the solution and partial pressure within the evaporator chamber. If contaminated sorbate vapor is detected in the adsorption chamber, or the temperature of the solution rises above the freezing point of the contaminated sorbate, or the partial pressure of the evaporator chamber deviates from the acceptable range of partial pressures, then during desorption, the sorbate vapor is directed to a contaminated condenser for recycling back to the solution. If contaminated sorbate vapor is not detected in the adsorption chamber, and the temperature of the solution did not rise above the freezing point of the contaminated sorbate, and the partial pressure of the evaporator chamber did not deviate from the acceptable range of partial pressures, then during desorption, the sorbate vapor is directed to a clean condenser where it is condensed and removed from the concentrator. | 02-23-2012 |
