Abstract: What had been created are various new processes with the corresponding newly created devices that support or to handle the new processes in order to attained the desired outcome of the new processes. One desired outcome is to produce a low technology cooling system that can be easily made by the ordinary man for himself and this is answered by the creation of a misting tube having a plurality of water misting nozzles and a blower blows wind thru the water mist towards a place or into a house or into an office.

Abstract: An evaporative cooler including a cross-flow plate heat exchanger formed by a plurality of stacked, fluted plates. The evaporative cooler may be operated in an indirect evaporative cooling process, or in a combined direct and indirect mode.
