Experimental and Numerical Investigation of Novel Dew-point Evaporative Cooler with Shell and Tube Design

Implementing a neoteric practical design for dew-point evaporative cooler (DPEC) rather than
the widely utilized flat plate and corrugated plate has been challenging since the first invention.
Thus far, no study has been dedicated to design and experimentally implement a shell and tube
concept for DPEC with an innovative configuration that can contribute in mass production,
globalization, and effortless maintenance of such a high performance cooling machine.
Therefore, in this paper, the shell and tube concept has been employed as a core design for
DPEC that has been reinforced by a practical approaches. The practical approaches include a
dedicated novel design for the proposed system and utilizing super cheap materials for the
system’s construction. Both of the aforementioned approaches provide solutions for
overcoming the aforementioned issues. In the meanwhile, the superiority of the proposed
DPEC has been approved by comparing it to the flat plate DPEC. During the experimentations,
the prototype was able to reduce the ambient temperature by up to 34.1°C (from 53°C to
18.9°C), besides, it could achieve a dew-point effectiveness of 99.6% and wet-bulb
effectiveness of 135%.
