High-Efficiency Radiant Cooling


Latest News > Case Studies

From the February 2009 issue of HPAC Engineering
by Greg Cunniff, P.E.

Injection pumping can reduce power demand of radiant-cooling systems

Radiant-cooling systems have progressed in the last few decades, garnering attention as a comfortable and energy- and material-efficient option.1 Compared with air systems, radiant-cooling hydronic systems use approximately half the horsepower and materials to move heating and cooling energy within a building. Although radiant-cooling systems have been used in Europe for years, they are starting to be examined—and installed—in the United States.

Low-flow injection-pumping systems can help make radiant-cooling systems even more efficient. Injection-pumping systems deliver heating and cooling energy to a variety of terminal units, including chilled ceiling panels, chilled beams, fan coils, and heat pumps, in the same piping-distribution system, even if each unit requires a different temperature....MORE
