    摘要: A device is disclosed for extracting water from a fluid medium. The water extracting device comprises a primary channel and a quantity of a light-activated, stimulus responsive polymer (SRP) supported on a carrier within the primary channel. The SRP is capable of absorbing a quantity of water from the medium in a first state and releasing the water in a second state and vice versa. An illumination arrangement allows selective exposure of the SRP within the primary channel to electromagnetic radiation to switch the SRP between the first state and the second state whereby water absorbed by the SRP is released. Also disclosed is a method and device for conducting heat from the primary channel to a secondary channel, adjacent to and in heat conducting relation with the primary channel.

    摘要: A two stage evaporative cooling device has a central chamber, divided into an upper chamber and a lower chamber by a divider. one or more heat exchange units surrounding the central chamber; an upper fan arranged above the upper chamber and a lower fan arranged below the lower chamber; and a water circuit; wherein each heat exchange unit comprises an evaporative cooling element and an air to water pre-cooler, the pre-cooler being placed ahead of a lower portion of the cooling element and the water circuit is arranged to irrigate the cooling element and collect the irrigated water below the cooling element for delivery to the pre-cooler whereby pre-cooled air may be drawn inwardly through the pre-cooler and the lower part of the cooling element by the lower fan and ambient air may be drawn inwardly through the upper part of the cooling element by the upper fan.
