Return air is drawn across the lower half of the Whalen riser heat-exchanger and blown across the upper half, thus duplicating, in effect, a four-row cooling coil. This design, combined with a comparatively large amount of both primary and secondary cooling surface in the finned riser coil, enables the system designer to utilize high delta-T and low GPM/ton where minimum pumping horsepower (and/or smaller piping) is the primary consideration. |
