Thermal Products

The Delphi Heat and Mass Exchanger (HMX) is a water-fueled air conditioning component that yields cooling, energy recovery, and ventilation systems with significantly improved efficiency and performance. A heating, ventilation, and air conditioning (HVAC) company incorporating the Delphi HMX into its products can produce an energy-efficient system that does not require a compressor or the use of chemical refrigerants. Such a system means fewer moving parts, no copper components, a reduced carbon footprint, and improved sustainability.

Delphi, under an exclusive license from Cooler Air Systems, LLC, manufactures a robust, high-quality supply of this indirect evaporative cooling component.

The editors of GreenSpec and Environmental Building News named the Coolerado Cooler, a revolutionary air conditioning system that features the Delphi HMX, a "Top-10" green building product in 2006. This award recognizes exceptionally innovative and eco-friendly products introduced to the market.

Benefits

• Reduced strain on power grid. In many fresh air applications, HMX-based systems can use as little as 25 percent of the power consumed by a traditional direct expansion system to do the same job—yielding savings of up to $75 USD on a $100 USD cooling bill.
• Exceptional performance under extreme conditions. The hotter it gets outside, the better the Delphi HMX works. That means the more extreme the outdoor heat, the greater the cooling capacity of the HMX and the higher the energy efficiency ratio (EER). EER is the ratio of the cooling capacity of the system to the power it consumes; traditional systems have an EER of 10 in these extreme conditions. With an EER rating of 40 and higher in extreme conditions, the Delphi HMX makes the most of its limited power consumption during periods of peak demand.
• Fresh air quality. The HMX consistently provides fresh, filtered outside air, in stark contrast to traditional air conditioning systems that rely on recirculated air and operate at lower efficiencies in extreme heat.
• Maximized comfort and minimized carbon footprint. The Delphi HMX outperforms other evaporative systems on the market by providing cooler and drier air. The HMX does not require the use of a compressor or any chlorofluorocarbon (CFC) refrigerants, which means fewer moving parts and improved sustainability.
• Modular system enhances versatility. The Delphi HMX is modular and units can be stacked as high and/or as wide as necessary to meet any cooling capacity requirement.
• Quiet operation. The Delphi HMX features quieter operation compared to comparable direct expansion systems.
• Includes Aegis Microbe Shield^® technology.

Operating Principle

Delphi's HMX operates by internally splitting the air into two streams:

• Working air incrementally pulls heat away from both itself and the product air before being discharged as exhaust.
• Product air is isolated in water-resistant channels throughout and exits the HMX as cool air with no additional moisture.

The HMX manages the heat load via an evaporative process through a thin plastic membrane between the product air and working air as it travels through the unique geometry of the HMX.

The thermodynamic principle behind the HMX is the Maisotsenko Cycle or M-Cycle, which harnesses a limitless supply of atmospheric energy to drive sensible cooling.

The Delphi Heat and Mass Exchanger is featured in the Cooleado Cooler™ series of residential and light commercial systems.

Typical Applications

The Delphi HMX can be used in homes as well as offices and is a natural fit for comfort cooling options, as evidenced by Coolerado's acclaimed lineup of residential and light commercial air conditioning units in the United States. Delphi is working with companies like Coolerado throughout the world to make HMX-driven systems readily available. These systems for homes and office buildings can be installed wherever it is convenient—attics or basements, outside, etc. Because it is an evaporative technology, stand-alone systems using the Delphi HMX are most effective when deployed in hot, dry climates. However, system designs capitalizing on the unique traits of the HMX can yield applications of all shapes and sizes suited to just about any environment or location.

HMX Suitability by Region

Dark Green—An HMX system for your home or business can provide all of the comfort of traditional air conditioning at dramatically lower operating cost. Reduce demand on the power grid during peak periods by capitalizing on the HMX’s unique ability to be most efficient when it is hottest outside. 

Medium Green—Depending on preference, an HMX system may be able to provide the benefits offered in the dark green regions of the map. The HMX is still indispensable in this zone for fresh air cooling and can be particularly effective for a kitchen, garage, office or workspace, etc.

Light Green—The HMX is useful in this zone for fresh air cooling for your home or office. It can be particularly effective for a kitchen, garage, office or workspace, etc. Custom systems in this zone can offer all of the benefits of the dark green region of the map.
