With new heat pump technology and R-32
refrigerant, Rebel® and Rebel
Applied® deliver industry-leading heating
capacity, simplified installation and enhanced efficiency
MINNEAPOLIS, July 9, 2024
/PRNewswire/ -- Daikin Applied today announced the addition of
air-source heat pumps to its award-winning lineup of
Rebel® and Rebel Applied® packaged rooftop
systems. With electricity-powered heat pumps, low-GWP R-32
refrigerant and ultra-efficient inverter compressors, the new Rebel
Applied and Rebel units will help building owners optimize comfort
and cost while decarbonizing their facilities. The units also
include features that increase performance, especially in cold
climates, and simplify installation for both new construction and
retrofits.
"We're not just making heat pumps available, we're also making
them practical for a wide range of applications," said Jim Macosko, vice president of product and
sustainability solutions at Daikin Applied. "Buildings account for
40% of global energy use and 33% of greenhouse gas emissions, which
is why they're central to mitigating climate change. By addressing
the historic limitations of heat pumps, we're making it easier for
customers to use this technology, electrify their HVAC systems, and
decarbonize in a way that benefits the environment and bottom
line."
Low Ambient Operation
Heat pumps face a capacity challenge — the colder the temperature,
the less efficient and effective a heat pump traditionally gets.
However, with inverter compressors and the unique operating
envelope of R-32, Rebel Applied and Rebel rooftop units are
proficient in lower ambient temperatures. With Rebel Applied, this
is accomplished with additional outdoor coil surface and a
supplemental compressor that kicks in when temperatures drop. In
Rebel, compressors have a boost function that ramps speeds up in
cold conditions to increase heating capacity.
Similarly, when used in a dedicated outdoor air system, the
performance of conventional heat pumps decreases significantly when
ambient air temperatures fall below 45 degrees Fahrenheit. To
address this limitation, the new Rebel Applied units have optional
features such as energy recovery wheels to pre-heat air before it
passes through the heating coil, extending the heat pump's capacity
once again.
Simplified Configuration
Switching from natural gas to electricity as an energy source is
not just about the equipment; it often requires changes to a
building's electrical infrastructure as well, which can increase
installation costs, especially in retrofit applications. Daikin is
making the transition easier and more cost effective, however.
By using configurable circuitry, and isolating new loads to
smaller and separate circuits, Rebel Applied and Rebel heat pumps
eliminate or minimize electrical infrastructure modifications,
trimming installation time and associated expenses. Further, the
rooftop systems offer auxiliary electric heat limits and emergency
backup controls that reduce the unit's peak design electrical
load.
Real-World Efficiency
Designed with R-32, the rooftop units are up to 20% more efficient
than predecessors with R-410A refrigerant. These new solutions are
ideal for schools and commercial office spaces where there are
common needs for comfort and space conditioning. The new heat pump
technology is just one part of Daikin's larger movement toward
solutions that are redefining sustainable heating and cooling.
