Helen, an vitality firm based mostly in Helsinki, has unveiled plans for a big district heating plant complicated. Germany’s MAN Energy Solutions equipped a 33 MW air-to-water warmth pump, the biggest used for a district heating plant, with ambient air and renewable electrical energy for heating.
The vitality firm Helen is constructing a big heating plant complicated in Patola, a neighborhood in Helsinki, Finland.
The web site options an industrial-scale warmth pump and two 50 MW electrical boilers. Once operational, it’s anticipated to cut back carbon emissions by 56,000 tons per 12 months. Construction will start later this 12 months, with a manufacturing begin date scheduled for the 2026-27 heating season.
“The air-to-water warmth pump plant to be constructed is the primary of its dimension on the earth, and certainly one of its key benefits is that it may be operated at exterior temperatures as little as -20 C,” stated Juhani Aaltonen, VP of inexperienced funding at Helen. “Furthermore, the plant is prone to create worth stability for patrons, as its manufacturing will be simply adjusted.”
German producer MAN Energy Solutions was commissioned to provide a 33 MW air-to-water warmth pump – the world’s largest utilized in a district heating plant. It operates at a capability from 20 MW to 33 MW, relying on the air temperature, offering warmth to round 30,000 properties in Helsinki.
The firm’s warmth pump answer makes use of ambient air as a supply of thermal vitality to extend water temperature and meet the wants of the district heating community. It says that toxicologically and environmentally protected carbon dioxide is used as a refrigerant for the system cycle, which permits it to ship warmth at temperatures as much as 90°C. The answer additionally permits speedy energy balancing within the electrical grid.
MAN Energy Solutions provides that the center of the system is an oil-free, hermetically-sealed HOFIM motor-compressor. “The compression unit makes use of a high-speed motor and energetic magnetic bearings, which permits it to function with out the necessity for a dry fuel seal system and the entire oil system,” stated the corporate.
Uwe Lauber, CEO of MAN Energy Solutions, stated that warmth pump know-how gives “an economically aggressive and environment friendly approach to make use of climate-neutral warmth from the ambient air… Urban district heating tasks utilizing climate-neutral applied sciences are important for advancing world efforts to cut back carbon emissions.
Finland’s Ministry of Economic Affairs and Employment supplied an vitality subsidy for the plant. The facility is predicted to help Helsinki’s purpose of changing into carbon-neutral by 2030.
