Heat and Mass Exchanger Helps Coolerado Earn Top-10 Green Building Award

The Coolerado Cooler, a revolutionary air conditioning system which features Delphi Corporation's Heat and Mass Exchanger (HMX), has been named a "Top-10" green building product for 2006 by the editors of GreenSpec and Environmental Building News.

The publications' editors made the announcement at the 2006 GreenBuild International Conference & Expo in Denver last month. Honorees were recognized for introducing exceptionally innovative products to the market.

Delphi's HMX is the "engine" behind the Coolerado Cooler, which is a new residential series of water-fueled, high-efficiency air conditioners. Air conditioning systems using the Delphi HMX can cool homes, office buildings and industrial spaces across the globe for significantly less operating cost than traditional cooling systems without generating greenhouse gas emissions.

Delphi signed an agreement last year with Cooler Air Systems LLC (CAS) of Arvada, Colo., to be the world's exclusive manufacturer of heat and mass exchangers. The Coolerado series of residential products, marketed by CAS affiliate Coolerado Corporation, is the first product line developed around this groundbreaking technology.

"Whether it is health and safety, the natural environment, or the economy, the built environment significantly impacts our lives," said Joseph Dunlop, commercial manager, Delphi Thermal Energy Systems. "Delphi is honored to be recognized for its commitment to develop and promote energy-efficient technologies that support building green and reduce the negative impact of technology on the environment."

As an indirect evaporative cooling system, the Coolerado Cooler relies on the evaporation of water to cool a space without raising humidity. It can deliver as much as six tons of cooling with an electrical consumption of 1,200 watts, which is a tremendous improvement over traditional air conditioners.

HMX - How it works

Delphi's HMX system capitalizes on a thermodynamic cycle known as the Maisotsenko Cycle or M-Cycle. The M-Cycle harnesses the endless supply of atmospheric energy to drive sensible cooling with maximum efficiency. In the case of the HMX, cool air is produced via the water-fueled M-Cycle without adding a drop of moisture.

The hotter it gets outside, the better the Delphi HMX works. The cooling capacity and Energy Efficiency Ratio (EER) of an HMX application increase along with the temperature outside, a feature which dramatically reduces power consumption during peak demand when power costs the most.

The HMX is modular, which allows HMX applications to be sized to any cooling capacity requirement. Because it is an evaporative technology, the Delphi HMX is most effective when used in stand-alone cooling solutions in hot, dry climates - but it can also be used for turbine inlet cooling and in concert with direct expansion systems, energy recovery systems, dehumidification systems and more to yield applications of all shapes and sizes suited to any environment.
