Heat and Mass Exchanger provides energy efficient cooling.

Press Release Summary:

Requiring no compressor or chemical refrigerants, HMX Heat and Mass Exchanger enables water-fueled air conditioners to cool homes, office buildings, and industrial spaces without generating greenhouse gas emissions. System capitalizes on thermodynamic M-Cycle, which harnesses endless supply of atmospheric energy to drive cooling. Cooling capacity and Energy Efficiency Ratio increase along with temperature outside, minimizing power consumption during peak demand.

Delphi Offers 'Green,' Cost-Effective Way to Cool with New Heat and Mass Exchangers

Technology enables water-fueled, high-efficiency residential, commercial and industrial air conditioners

"Green" benefit: System requires no compressor or chemical refrigerants

Cost benefit: System can save up to 75 percent of electricity compared to traditional A/C systems

TROY, Mich., Nov. 15 /-- Delphi Corporation has begun production of the Delphi Heat and Mass Exchanger (HMX) -- the "engine" behind new water-fueled, high-efficiency air conditioners that 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 officials made the announcement today at the 2006 GreenBuild International Conference & Expo in Denver.

"Before Delphi took over the manufacturing of the HMX, supply was unable to meet the rising demand for this revolutionary cooling component. Now, anyone who wants an environmentally-responsible cooling system that offers superb performance at a significantly lower cost can get one without delay," said Raymond Johnson, product business unit director, Delphi Thermal New Markets.

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.

The Coolerado Cooler was recognized in 2004 by R&D Magazine's 100 Awards program as one of the year's most technologically significant products introduced to the world.


The HMX 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 excellent 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.

"Because of this unique trait, these systems can always provide fresh, filtered outside air," said Rick Gillan, president, Coolerado Corp. "This stands in stark contrast to traditional A/C which relies on re-circulation of the air inside a home or building due to a diminished capacity to cool as the outdoor temperatures increases. A traditional system will therefore have a lower EER and draw more power when you need cooling 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 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.


Independent confirmation of the Delphi HMX's performance has come from the U.S. Department of Energy's National Renewable Energy Laboratories (NREL), Pacific Gas & Electric, and the Sacramento Municipal District.

"Systems that include the HMX do not require a compressor, which should dramatically reduce noise versus direct expansion systems," said Steve Slayzak, senior project manager, Center for Buildings and Thermal Systems, National Renewable Energy Laboratory, a U.S. Department of Energy research laboratory. "Taken together with the fact these systems use only a fraction of the electricity and no ozone-depleting chemical refrigerants, the benefits are as obvious as they are compelling."


The HMX is an air-conditioning component that is better for the environment and kinder to customers' wallets.

HMX applications require no compressor or chemical refrigerant and can have an energy-efficiency rating (EER) well in excess of 40.

In many applications, these systems use about four times less electricity than traditional air conditioners to do the same job -- which can mean a savings of $75 per month for someone spending $100 per month on electricity to run an existing direct expansion A/C system.

"Going 'green' has never been easier. This product is perfect for applications where there is an obligation to provide some percentage of outside air -- large retail spaces for instance -- regardless of geographic location," said Joseph Dunlop, commercial manager, Delphi Thermal Energy Systems.

Any homeowner or business can benefit from the affordable cooling offered by applications featuring the Delphi HMX, Johnson said.

"Even where A/C systems are already installed, our truly unique blend of value and comfort is undeniable. Delphi is committed to bringing this new product to as many customers as possible. It is the rare occasion where groundbreaking technology meets global responsibility."
