Chiller Feature
Huge chillers with small footprint
DAIKIN APPLIED IN the United States is set to introduce its first chillers based on the low GWP HFO refrigerant R1233zd.
The WLP Aptitude low pressure oil-bearing centrifugal water-cooled chiller and its magnet- ic-bearing WMT Magnitude stablemate will be available later this year.
“BOTH CHILLERS BOAST THE SMALLEST FOOTPRINTS BASED ON COOLING CAPACITY.”
The new chillers were a feature of the compa- ny’s stand at the AHR Expo earlier this year.
Designed for easy installation and reliable operation, both chillers, although huge, are said to feature the smallest footprints in the indus- try compared to equipment with the same cool- ing capacity.
Chillers employing R1233zd refrigerant are not new. Trane, Carrier, Johnson Controls York and MHI have all previously introduced chillers using the low GWP, A1, refrigerant.
The Magnitude chiller builds on Daikin’s lat- est magnetic bearing technology, which elimi-
Daikin’s Aptitude chiller was on show at AHR Expo.
ENGIE REFRIGERATION GMBH has an- nounced plans to expand its heat pump division. The refrigeration and heating specialist said it will produce all the CO2 high- temperature heat pumps in its portfolio at its head office in Lindau
on Lake Constance.
ENGIE Refrigeration CEO, Jochen Hornung,
said that in the course of this process, the existing production site in Ottendorf-Okrilla near Dresden will be shut down. ENGIE Refrigeration acquired the site in July 2018 from the insolven-
cy assets of Hafner-Muschler Kälte- und Klimatechnik.
“We have been producing chillers
in Lindau for customers around the
world for many years. Our employ-
ees have extensive experience in the
production of machines with a high
performance range, and will now
apply this expertise to the produc-
tion of our CO2 high-temperature ENGIE Refrigeration heat pumps,’ Hornung said. CEO, Jochen Hornung.
nates oil, seals, gears and wear surfaces for longer machine life. This allows the equipment to run at peak levels, with efficiencies said to be 40% better than standard centrifugal chillers.
The Magnitude is said to be capable of per- forming at full load efficiencies as low as 0.49kW/tonne with part load values as low as
0.29kW/tonne. Its RapidRestore feature will ensure quick restart times, the company says. In addition, Daikin maintains that the high temperature of water leaving the evapo- rator makes the technology best suited for mission critical applications like data cen- tres and hospitals.
ENGIE Refrigeration expands heat pump division
ENGIE Refrigeration will now use its state- of-the-art plant and the logistics network es- tablished in Lindau to sell its heat pumps as well, thereby raising synergies and further in- creasing efficiency in its production and distri- bution processes.
“With this decision, ENGIE Refrigeration has clearly achieved its strategic objective of adapting the high production standards of its entire prod- uct portfolio to its CO2 high-temperature heat
munal and industrial heating networks. The heat pumps use the natural refrigerant CO2, which has the technical name R744. It is assigned to safety group A1 for its low toxicity and low level of flammability, which means that flames do not spread, and is inexpensive to procure. In addition, it has a GWP (global warming potential) value of just 1, and thus far lower effects on the earth’s atmosphere than
traditional refrigerants.
When used in heat pumps, it contributes to
the mission of ‘Zero Carbon Transition as a Ser- vice’, which the French ENGIE Group, the parent company of ENGIE Refrigeration, has set itself.
To this effect, ENGIE Refrigeration plans to further expand its heat pump division at its site in Lindau on Lake Constance over the coming years.
“We will overhaul the existing thermeco2 heat pumps over the course of 2020 and align them even further with current and future market re- quirements,” Hornung said. ✺
pumps and thereby offer customers the best possible refrigeration and heating solutions,” he said.
“The CO2 high-temperature heat pumps are an important component of the product and service portfolio at ENGIE Refrigeration.”
They can reach effective tempera- tures of up to 110 degrees Celsius, and are therefore used, for example, in the field of heating, in drying technology, and in the provision of heat in com-
