A conditioning apparatus for conditioning a treated fluid includes a conditioning chamber for containing a flow of a treated fluid and an exchange element disposed within said conditioning chamber having one or more fluid passages formed therein filled with a saline solution. The exchange element has a semi-permeable membrane that allows fluid transfer between said treated fluid and said saline solution through said semi-permeable membrane.
An object is to provide an air conditioner in which a desiccant air conditioner is combined with a refrigerating device to cool an indoor by a refrigeration cycle including a compressor and the like and in which a drop of energy efficiency is suppressed. An air conditioner 200 includes a desiccant air conditioner 220 and a refrigerating device 210 which cools the indoor by a usual refrigeration cycle, this refrigerating device 210 has an auxiliary heat exchanger 17 between an outlet side of a heater 12 and an inlet side of an expansion valve 14, and this auxiliary heat exchanger 17 is disposed externally from an exhaust air passage 4 and a supply air passage 3.
A cooling system which utilizes a movable frame positioned within a duct. The moveable frame has an evaporative pad and where a nozzle is positioned to spray water onto the evaporative pad such that the weight of the water causes the frame to move to a lower position, thereby shutting-off the water flowing to the nozzle. As the water in the evaporative pad evaporates, the frame shifts to an upper position where the water is again sent through the nozzle to the evaporative pad, and the cycle repeats itself.
