Delphi ’Greens’ Stationary Air Conditioning Market; Strengthens Micro Channel Heat Exchanger Portfolio with New Products, Updated Technology

Company displays MCHX® evaporator and MCHX® condenser at Chillventa 2010 show


NUREMBERG, Germany — With industry, government and the general public looking for ways to make homes and buildings more energy efficient, Delphi’s family of MCHX® heat exchangers using micro channel technology can help green homes, offices and schools without compromising comfort. The innovative technology is on display at the Chillventa 2010 International Trade Fair for Refrigeration, Air Conditioning, Ventilation and Heat Pumps Oct. 13-15 at the Nuremberg exhibition center. (Delphi’s booth: Hall 2, Stand 2-603).

Delphi’s MCHX® heat exchanger technology uses a compact design that is more efficient than traditional tube-and-fin heat exchangers. The system joins three key components — the flat micro-channel tube, the fins and two refrigerant manifolds — brazed together in a single coil. The optimized coil design provides a high rate of heat transfer while maintaining low air-side pressure drop. This compact design and optimized coil makes it highly-efficient without cutting any performance.

Delphi MCHX® Heat Exchanger Benefits

Delphi’s MCHX® heat exchanger technologies help OEMs meet higher Seasonal Energy Efficiency Ratio (SEER) requirements in a smaller package. Delphi can help OEMs meet the required minimum 13 SEER while maintaining the same size package as a 10 or 12 SEER unit.

“Meeting 13 SEER with the same size package as a 10 or 12 SEER unit means greater energy efficiency, increased heat transfer, smaller, lighter packaging and reduced refrigerant usage compared to traditional tube and fin designs,” said Charlie Clevenger, product line director, Residential and Commercial Heat Exchangers, Delphi Thermal Systems.

Because Delphi’s MCHX® heat exchangers are at least 30 percent smaller than other residential heat exchangers, customers will also realize the additional benefits of less storage space, easier installation and greater aesthetics for their end consumers.

“Additionally, all Delphi micro channel products use up to 40 percent less refrigerant, which helps OEMs cut costs while still helping protect the environment from harmful emissions,” said Clevenger. “And since the micro channel products are 100 percent aluminum and easy to recycle, they provide a more environmentally-friendly solution to address today’s environmental concerns.”

Delphi has been at the forefront of micro channel technology developments since the debut of its micro channel condenser in 2003. The company has now added an indoor evaporator and second-generation condenser to its portfolio.

Micro Channel Evaporator

Delphi’s MCHX® evaporator is a specially-designed heat exchanger capable of performing in both condensing (heating) and evaporating (cooling) modes. It cuts 40 percent of the mass of a competitive product while achieving SEER requirements. Like all Delphi micro channel technologies, it reduces the amount of refrigerant needed in the system. With its all aluminum construction, Delphi’s MCHX® evaporator also eliminates formicary corrosion, as seen with traditional copper tube evaporator coils.

“Given the success of our micro channel condenser technology in the HVAC market, our customers can also now benefit from this new introduction into Delphi’s micro channel family,” said Shri Joshi, chief engineer, Residential and Commercial Heat Exchangers, Delphi Thermal Systems. “Because of our 25 years of micro channel heat exchanger experience, we’re quickly able to meet the demands of this market with energy-efficient, high-tech product offerings.”

Second-Generation Micro Channel Condenser

Earlier this year, Delphi launched the second generation of its successful MCHX® condenser. First introduced in 2003, the original condenser utilized Delphi’s unique micro channel design, making it a compact but efficient heating and cooling option for OEMs.

Building on this success, Delphi introduced an updated condenser with several enhancements that still provide top-notch performance while increasing product robustness and cutting installation complexities.

Currently available to OEMs, the new condenser utilizes an optimized alloy that is more corrosion resistant for outdoor applications.

“Delphi’s second generation condenser has the same performance and efficiency benefits, but now is more robust and easier for OEMs to install in their systems,” said Chris Day, global sales manager, Residential and Commercial Heat Exchangers, Delphi Thermal Systems. “It allows our product engineers to look toward further enhancements that will take the MCHX® condenser to the next level.”

Building on Automotive Success

Delphi produces more than 37 million heat exchangers at its global facilities every year for vehicle manufacturers and a number of residential and commercial HVAC manufacturers. With more than 100 years of experience in automotive cooling, Delphi led the automotive industry in the transition from tube and fin systems to heat exchangers. The company leverages 25 years of experience developing micro channel heat exchangers for automotive air conditioning systems for its work with residential and commercial HVAC manufacturers.
