Publication number: 20230406730Abstract: A desalination system and a method for operating the desalination system. An example desalination system includes a partitioned container, a membrane container housing a cross-flow semipermeable membrane, a feed pump for supplying saline water, a recirculation pump, a main valve, a bypass valve and a purge valve. The system operates in a first pressurisation stage where saline water is provided by the feed pump while the bypass valve is open, followed by a second pressurisation stage where an upstream compartment of the container is filled and a recharge stage where the main valve is closed and concentrated saline water is purged via the purge valve. An inlet valve may be provided, which is closed in the first pressurisation stage and open in the second pressurisation stage and recharge stage.Type: ApplicationFiled: November 5, 2021Publication date: December 21, 2023Inventors: Philip Davies, Timothy Naughton, Liam Burlace, Kiho Park

Patent number: 11431262Abstract: A system (10) for converting power comprising a plurality of modules (14) connected in series and having each at least one DC power source. Storage devices (18) are provided with each module (14) to store power from the power source and voltage control circuitry (19) in each module (14) connects the storage device between a maximum module voltage, a minimum module voltage to create a stepwise approximation of a mains signal. A compensator unit (20) is provided in series with the modules (14) including a storage device charged by the power sources. While each of the modules (14) is supplying either its maximum or minimum voltage to the system a control unit ramps up or down the voltage between the input and output of the compensator unit (20) to follow the desired AC signal.Type: GrantFiled: June 5, 2015Date of Patent: August 30, 2022Inventors: Kevin Stephen Davies, Alexander Philip Davies

Patent number: 10222087Abstract: The present invention relates to a system and method of cooling by latent energy transfer and, in particular, to cool a fluid by discharging unwanted low temperature thermal energy to a surrounding ambient environment utilizing a fluid evaporation process involving permitted or forced ventilation of air across a surface area of a heat transfer fluid. The invention further relates to an air treatment system utilizing the cooled heat transfer fluid for cooling air and for supplying ventilation air to the evaporation process. A body of liquid is cooled close to the prevailing wet bulb temperature, discharging unwanted thermal energy to the surroundings, rendering the liquid suitable as a cooling medium for removing unwanted thermal energy from a location or in a process.Type: GrantFiled: October 27, 2015Date of Patent: March 5, 2019Assignee: Intex Holdings Pty LtdInventor: Roger Philip Davies

Patent number: 10184675Abstract: The present invention relates to a dehumidification system and method and, in particular, to a system and method for controlling the humidity of air in a process or location using a desiccant-coated fluid-air heat exchanger. The desiccant material adsorbs water at or above ambient temperatures during an adsorption cycle, and the resultant air stream is of a reduced humidity compared with the humidity of the supply air. The desiccant material may then be dried during a regeneration cycle through addition of heating fluid through the heat exchanger, driving water back into the vapor state with addition of latent energy of vaporization. The desiccant material may be cooled, during the adsorption cycle, through addition of cooling fluid through the heat exchanger to maintain the temperature within a range sufficient for water vapor to be removed from the stream of air.Type: GrantFiled: October 27, 2015Date of Patent: January 22, 2019Assignee: Intex Holdings Pty LtdInventor: Roger Philip Davies

Patent number: 10135362Abstract: Described is a method for converting power including controlling operation of a plurality of series connected modules including a DC power sources and storage devices such that the total voltage across the series connected modules includes an AC signal. A storage parameter is defined based on a sum of a function of the voltages in the storage devices in the modules and one or more voltage control levels are defined for each of or a plurality of the storage devices. An average current drawn from the series connected modules over a time period is set such that the storage parameter approaches a target value. The target value is decreased for a subsequent time period in the event that none the voltage control levels are reached and increased in the event that one or more of the voltage control levels are reached.Type: GrantFiled: July 1, 2015Date of Patent: November 20, 2018Inventors: Alexander Philip Davies, Kevin Stephen Davies
