GERMANY: A high-temperature warmth pump using small GWP refrigerant R1234ze is established to begin entire-time operation at the district heating, electricity and cooling centre in Berlin’s Potsdamer Platz.
The Qwark³ (Quartiers-Wärme-Kraft-Kälte-Kopplung or coupling of district heating, electrical power and cooling) venture, is envisioned to go into continual operation in November, generating about 55GWh of warmth a calendar year.
It is the consequence of a challenge involving Siemens Energy AG and German electricity company Vattenfall Wärme Berlin AG, with funding by Germany’s Federal Ministry of Economics and Climate Protection.
All around 30,000 homes will be supplied with sizzling drinking water in summer time and 3,000 households with warmth in winter season. “In whole, the technique will save about 6,500 tons of CO2 in the city’s heating process,” explained Vattenfall CEO Tanja Wielgoß. “That corresponds to 3.2 million m3 of natural gasoline.”
For Christian Bruch, CEO of Siemens Strength, the pilot job is an essential milestone: “High-functionality, substantial-temperature heat pumps will enjoy an significant function in the power changeover and the decarbonization of city heating. Together with Vattenfall, we are screening this sort of a alternative in this article in Berlin for the initially time below genuine situations.”
In the future, the superior-temperature heat pump will be aspect of Germany’s major district cooling community.
For 25 decades, the cooling centre at Potsdamer Platz has been giving all over 12,000 places of work, 1,000 residences and cultural services this sort of as the Philharmonie or the Kulturforum with regionally generated cooling.
Now, the cooling community supplies the linked buildings with cold drinking water at a temperature of 6ºC all calendar year round. It returns to the cooling centre at up to approximately 12ºC.
The new large-temperature heat pump, which the Cooling Publish thinks is employing the low GWP HFO refrigerant R1234ze, will use this waste heat from the cooling h2o and elevate its temperature to 120ºC.
“This also saves 120,000m3 of cooling water,” Bruch described. “We are giving just one of the world’s initially heat pumps for the refrigeration centre that can produce this kind of superior temperatures in the 8MW ability assortment. For this purpose, a new, environmentally-pleasant refrigerant is applied in the heat pump.”
