Abstract: 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 vapour 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 vapour to be removed from the stream of air.

Abstract: 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 utilising 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 utilising 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.

Abstract: The present invention relates to a solar energy collection apparatus and design method. In particular, the invention provides a solar energy collection apparatus incorporating one or more reflectors and a solar collector for receiving incoming solar radiation, including reflected radiation from the one or more reflectors, wherein the one or more reflectors and the collector are oriented according to a pre-calculated offset length and offset angle based at least on the latitude of the apparatus. The invention further provides a computer-implemented method of designing a solar collection apparatus including determining the optimal offset length and offset angle between the one or more reflectors and the collector for a given latitude and other inputs.
