Daikin launches a
new generation of high efficiency air-cooled scroll chiller series with
refrigerant R-32.
The new Air-cooled
chiller range (EWAT~B) will be available for cooling only and heat recovery
applications from 80 kW up to 700 kW cooling capacity at nominal conditions.
Compared to the
previous R-410A range, seasonal energy efficiency ratio (SEER) is improved by
10%. The chiller range fully complies with the efficiency requirements imposed
by current European Legislation (Ecodesign Lot21).
Daikin is the first
in the market to introduce R-32 refrigerant in this sector.
The Global Warming
Potential is 675, which is only one third of the commonly used refrigerant
R-410A.
The selection of
R-32 (chemical name difluoromethane) minimises the global warming impact of
scroll compressor chillers thanks to the lower Global Warming Potential in
combination with high energy efficiency.
Daikin, involved in
both HVAC and refrigerant businesses, was the world’s first company to
introduce R-32 in split air conditioners in 2012, and has expanded the range in
the past years to include commercial air conditioners and heat pumps. As of
December 2017, Daikin had sold approximately 12 million R-32 units in more than
50 Countries.
Thanks to the lower
flammability classification (R-32 refrigerant falls into category class A2L in
ISO817), it can be safely used in many applications including chilled water
systems. As a single component refrigerant, R-32 is also easier to recycle and reuse,
another environmental plus in its favour.
The new Daikin
chiller series will be available with two efficiency versions (Silver and
Gold), combinable with three sound configurations (Standard, Low and Reduced)
and providing full customisation on project-specific requirements.
An extensive list of
options and accessories can be provided on request, such as the fully
integrated hydronic kit for fixed flow or variable flow operation, partial or
total heat recovery for sanitary hot water production and many other solutions.
The new series is
fully compatible with the Daikin on Site cloud-based platform, which offers a
number of advanced functionalities including remote monitoring, system
optimization and preventive maintenance.
More than that, the
new Daikin series comes with Master/Slave functionality as standard, allowing
the management of up to 4 units on the same system without the need for
external control devices.
For
more complex installations (e.g. higher number of units, peripherals’ control …
etc.. ), Daikin can offer the Intelligent Chiller Manager option, allowing
energy optimisation of the system and, when necessary, full customisation of
the control solutions to the specific installation’s needs.
