Delphi Introduces MCHX Outdoor Heat Pump Coil; Industry First, Ends Compromise

  Delphi Introduces MCHX Outdoor Heat Pump Coil; Industry First, Ends

Business Wire

DALLAS -- January 29, 2013

Outdoor heat pump coils with copper tubes and fins have been used in
residential and commercial heating and cooling systems for decades. These
coils are inefficient, heavy and cost more to manufacture than “cooling only”

This has pushed today’s cost-cautious, green-focused industry to ask: Is there
something better?

Delphi thinks there is.

Following its success with the MCHX® condenser and evaporator, Delphi is now
launching the first of its kind Delphi MCHX Outdoor Heat Pump Coil. The coil
operates outdoors in an air-sourced heat pump system, and functions as a
traditional condenser in cooling mode and as an evaporator in heating mode.

It is up to 50 percent lighter, 30 percent smaller in volume, 100 percent
recyclable, provides up to 40 percent less refrigerant usage and uses a unique
and efficient defrost process.

Additionally, in the past, using an indoor micro channel coil with an outdoor
copper tube and fin coil caused a significant charge imbalance, which required
more refrigerant usage and loss of efficiency. Now OEMs can end the compromise
in performance by using Delphi’s micro channel technology both inside and
outside so the charge imbalance is eliminated and the system performs
optimally with a lower refrigerant charge.

“It’s the first time manufacturers are receiving the highest level of system
performance from micro channel technology,” said James A. Bertrand, president,
Delphi Thermal Systems. “In fact, we are already seeing efficiency results
today for SEER and HSPF near Department of Energy (DOE) 2015 ratings, based on
current system integration testing.”

How does Delphi do all this?

“Delphi’s innovative approach virtually eliminates the traditional
inefficiencies of the heat pump coil just by applying its micro channel
technology and its 100-plus years of automotive cooling system engineering
know-how,” Bertrand said.

The Delphi MCHX^® family uses brazed aluminum construction and is based on the
micro channel technology, which consists of three components: a flat micro
channel tube, fins and two refrigerant manifolds joined together in a single
coil. The “channels” provide more fluidity, cohesion and efficiency than round

“Think about standing on a bridge with water flowing underneath. When water
goes over the pylons the flow is disrupted, but if the pylons were long and
flat—like channels—water would move over the surface with more contact and
fluidity,” said Bertrand.

This unique construction makes all of Delphi’s MCHX products up to 50 percent
lighter and 30 percent less bulky than those with traditional copper tubes and
fins. They are easier to install and help manufacturers receive an LEED credit
due to increased energy efficiency, reduced mass and use of 40 percent less
refrigerant. And with proper maintenance the micro channel units keep the
system running at near peak efficiency much longer without the degradation.

Delphi’s MCHX products will be on display at the AHR Expo being held Jan.
28-30 at the Dallas Convention Center at Delphi’s booth located in Hall F,
booth No. 3419.
