A heat exchanger assembly, an indirect evaporative heat exchanger including the heat exchanger, and methods of operating the same. The heat exchanger assembly includes at least one tube, a plurality of sections, and a plurality of nozzles. The at least one tube is configured to (i) have a process fluid flow therethrough in a first direction and (ii) have a scavenger cooling medium flow over the outer surface of the tube in a second direction. The second direction intersects the first direction. The plurality of sections is aligned in the first direction. The plurality of nozzles are located above the at least one tube. At least one nozzle of the plurality of nozzles is (i) located in each of the plurality of sections and (ii) configured to selectively discharge coolant onto the portion of the tube in that section of the heat exchanger.

Disclosed herein are fiber reinforced cement composite materials incorporating a fiber blend that includes cellulose pulp and synthetic fibers in a ratio selected to provide the composite material with improved water absorption characteristics and the same or improved mechanical properties as compared to equivalent composite materials reinforced with predominantly or all cellulose fibers. Also disclosed herein are fiber blends comprised of a combination of cellulose fibers and polypropylene fibers adapted to reinforce cementitious composite articles manufactured by the Hatschek process and autoclave cured.

A direct evaporative air handler for providing supply air to humidify and cool an enclosed space such as a data center. The air handler includes an evaporative cooler and a return air port that is positioned upstream of the evaporative cooler to allow recirculated air from the enclosed space to pass through the evaporative cooler. The air handler includes an additional return air port that is positioned downstream of the evaporative cooler to allow recirculated air from the enclosed space to bypass the evaporative cooler. The air handler includes an outdoor air port that is positioned upstream of the evaporative cooler to allow outdoor air to pass through the evaporative cooler and further includes an outdoor air bypass port that allows outdoor air to enter the air handler without passing through the evaporative cooler. The temperature and humidity of the supply air can be controlled under various ambient conditions by controlling the amount of air that enters the air handler through each port.
