rooms and bedrooms. Pedotherm GmbH was responsible for engineering the underfloor heating and the controlled room ventilation with integrated heat recovery.
One of the system's special features is the combination
of panel heating and quick-response air heating during changes of season. This is with an active cooling and
dehumidifying function in the living and sleeping areas
and controlled home ventilation in the form of an infloor system with heat recovery.
A refrigeration plant that expanded capabilities of
pharmaceutical manufacturer Biotest AG was selected in
the commercial refrigeration category. One of the customer's specifications was to only use natural refrigerants while delivering a total of 100 kW for frozen storage
and 30 kW for temperature control, hot air curtains and
precooling. All machines had to come with 100% redundancy. Operational safety, short downtimes and the
need to observe the latest requirements of Germany's

Energy Saving Ordinance (EnEV 2015), the Renewable
Energy Act, the Ecodesign Directive 2009/125/EC and
the F-Gas Regulation were all essential conditions. KKR
Kälte-Klima-Reinraumtechnik GmbH worked with system supplier compact Kältetechnik GmbH on an option
that uses four CO2 assemblies generating an ambient temperature of -35°C (-31°F) in the storage areas
through direct expansion. Cooling for the cascade stages
is provided using cooling brine at -8°C (17.6°F). Eight
cold-water sets using propane as a refrigerant produce
the brine. The eight machines and the resulting eight
individual circuits make small refrigerant fill volumes
possible for each circuit.
The Chillventa awards are expected to be an ongoing feature of the trade fair, allowing for progress and
implementation of successful solutions to be tracked.
The next Chillventa is scheduled for October 13 - 15,
2020, details at www.chillventa.de.

Adding an organic solvent to a water-based turbulent
heat exchange system creates bubbles, removing
heat.

Boosting Heat Exchanger Capacity
PROVIDENCE, R.I.-Researchers from

Brown University and Tsinghua University have devised a
way to dramatically speed up
turbulent heat exchange. The
new method works by adding an
organic solvent to a water-based
turbulent heat exchange system.
The researchers experimented
with the additive for three years
to maximize the speed of heat
transfer. The additive is non-corrosive, non-flammable and ozone
friendly.

CHICAGO-Rittal is partnering with ABB

and Hewlett Packard Enterprise to
provide a turnkey edge data center
solution for industry and telecommunications environments. The
resilient micro-modular data centers
will be purpose-built for rough
environments. The Secure Edge
Data Center allows customers to run
enterprise-grade IT near their operational technology environments,
machines and equipment to enable
low-latency, secure and reliable digital processes.

slaughterhouse in 1973 by FabricAir's
precursor, and the company made
its North American market penetration in 1989. Today, FabricAir
continues to innovate and expand,
including its new research and development AirLab.
