SHANGHAI, November 30, 2009 -- Carrier
Corp., a world leader in the heating,
ventilation, air-conditioning and
refrigeration (HVACR) industry, introduced
to the China market the Aquaforce® 30XW
water-cooled screw chiller, with capacities
ranging from 133 to 500 refrigeration tons
(RT) and increased energy efficiency.
Carrier is a business unit of United
Technologies Corp. (NYSE:UTX).
In 2006, with the original launch of the
Aquaforce air-cooled chillers, Carrier
created a new category of
energy-efficient chillers in China. Now
Carrier expands this concept into the
water-cooled chiller market. “Carrier
has been introducing world leading
products and technologies to the China
market for many years,” commented Ross
Shuster, president, Carrier Asia HVAC.
“The new AquaForce 30XW chiller is no
exception. Its innovative design uses
Carrier’s latest screw compression
technology, employing the
environmentally sound refrigerant,
non-ozone depleting, HFC-134a.”
Achieving Grades One and Two under
China’s National Energy Efficiency
Standard, the Aquaforce chiller is more
affordable to operate, reduces building
energy consumption and is up to 20
percent more efficient than its
predecessors. The chiller performs at
the COP of 5.7 under full load condition
and NPLV of 7.1 under part load
condition.
Integrating innovative technologies, the
AquaForce® 30XW provides exceptional
energy performance. The high efficiency
06T dual screw compressor, which is
specifically designed to utilize
non-ozone depleting HFC-134a
refrigerant, applies Carrier’s patented
design for screw rotors. Electronic
expansion valves accurately control
refrigerant flow and adjust the
temperature of evaporator exit to
maintain higher efficiency of cooling
circulation, and the advanced
microcomputer control system helps
achieve efficient operation
automatically.
“As green building designs demand ever
more efficient HVAC systems, Aquaforce
chillers are an ideal option, providing
a high performance sustainable solution
that reflects Carrier’s innovation in
HVAC systems design,” commented Victor
Xiao, director, product marketing,
Carrier Asia HVAC.
With its high efficiency design,
Aquaforce chillers adapt to a wide range
of applications and customer
requirements, while satisfying the
different needs of each market segment –
heating, air conditioning, and
industrial. The Aquaforce 30XW offers
flexible, energy-efficient solutions for
commercial building owners.
The 30XW chiller is an ideal choice for
ice storage systems installed in large
commercial and public facilities and can
be incorporated into Leadership in
Energy and Environmental Design (LEED®)
Green Building Rating System™ projects.
Its unique dual-duty function uses
advanced touch screen control, ensuring
automatic switch between air
conditioning and icing, while the dual
screw compressor ensures stable and
highly efficient operations under both
conditions.
The Aquaforce® 30XW can also offer hot
water as high as 63°C for air
conditioning, heating and domestic hot
water supply. For water source heat pump
applications, the chiller leverages
various recyclable low-temperature heat
sources, including ground source,
underground water, or surface water (for
example, lake or river water). Through
these methods, the chiller reaches
heating COP of 5.0, dramatically
reducing expenses as compared to
boilers.
The chiller’s compact footprint is up to
30 percent smaller than other chillers,
allowing for less mechanical room floor
space. The smaller footprint also allows
for easier installation in building
retrofits.
The Aquaforce® 30XW’s dual independent
refrigerant circuits provide reliable
cooling, increased part load operation,
and redundancy. The chiller employs
industrial-type screw compressors with
oversized bearings. All the compressor
components are easily accessible on site
for minimal down-time.
“The introduction of the new Aquaforce®
30XW water-cooled screw chiller is yet
another example of Carrier’s leadership
in offering global products while still
providing customized features to meet
the requirements of commercial building
owners in the China market,” added Eric
Wei, managing director, Carrier China
Distribution and Aftermarket.
